Cracked plastic may be caused by thermal shock as well as overtemperature so cooling rate should also be checked. The guardring datasneet operates like a zener to absorb overvoltage transients.
Motorola products are not designed, intended, or autho- rized for use as components in systems intended for surgical implant into the body, or other applications intended to support or sustain life, orfor any otherapplicationinwhichthefailureofthe Motorola product could create a situation where personal injury or death datasbeet occur. It can be seen from this equation that if satasheet Vqd voltage is low compared to the breakdown voltage of the device, the amount of energy contributed by the supply during breakdown is small and the total energy can be assumed to be nearly equal to the energy stored in the coil during the time when Si was closed, Equation 2.
These fluxes range from a mild rosin to a strong acid; e.

Typical Forward Voltage Figure 3. First is the chip, which has an interface metal between the platinum-barrier metal and nickel-gold ohmic-contact metal to eliminate any possible interaction with the barrier.
This confirms that the avalanche current is vertical and not only a surface or passivation related phe- nomenon. Typical Reverse Current Figure 5. The part adtasheet listed in this Cross Reference are in computer sort. Average forward power dissipation Average reverse power dissipation Junction-to-ambient thermal resistance Figures 1, 2 and 3 permit easier use of equation 1 by taking reverse power dissipation and thermal runaway into consideration. Typical reverse current- for lower voltage selections can be estimated from: Duty Cycle sg 2.
Power dissipation for a surface mount device is determined by Tj max. For R0JL t values at pulse widths less than 0. Washing is mandatory if an acid flux is used because of its ionic and corrosive nature.
State-of-the-art geometry features chrome adtasheet metal, epitaxial construction with oxide passivation and metal overlap contact.

Lever Pull lbs max fatasheet lbs max Note: These stencils are typically 0. The data was used in Equation 1 to obtain points for Figure 9. Finally, when the punchthrough reaches considerable dimen- sions, the device looks very similar to a low value resistor.
The guardring also operates like a zener to absorb over-voltage transients. Power dissipation for a surface mount device is determined by Tj maxthe maximum rated junction temperature of the die, Rqja, the thermal resistance from the device datssheet to ambient, and the operating temperature, Ta- Byyw80 the values provided on the data sheet, Pq can be calculated as follows: Using a board material such as Thermal Clad, an aluminum core board, the power dissipation can be doubled using the same footprint.
Screw or Clip Mounting Position Figure 4. Power Dissipation Mounting method 3 per note 1. The device is tested before assembly in “sandwich” form, with the chip between the moly disks. Ideally suited for use in low voltage, high frequency switching power supplies, free wheeling diodes, and polarity protection diodes. Also note the minimum lot size is one full reel for each line item, and orders are required to be in increments of the single reel quantity.
Satisfactory circuit analysis work may be performed by using a model consisting of an ideal diode in parallel with a variable capacitance. Strain Relief Terminal for Button Rectifier This stress relief to the button should also be chosen for maxi- mum contact area to afford the best heat transfer — but not at the expense of flexibility.

Rectification efficiency measurements showthat operation will be satisfactory up to several megahertz. Button holding fixtures for use during soldering may be of various materials.
Typical reverse current – for lower voltage selections can be estimated fromr these curves if Vr is sufficiently below rated Vr. Dayasheet Forward Voltage 4.
Rectification efficiency measurements show that oper- ation will be satisfactory up to several megahertz. A proper character- ization should present the maximum power capability versus time. The temperature must be adjusted until the proper solder fillet is obtained within the maximum temperature limits. The standard characterization method consists in increas- ing the peak current in the inductor until the device fails. Any rejects can be reworked as required.
The two profiles are based on a high density and a low density board. The data was used in Equation 1 to obtain points for Figure Full text of ” motorola:: For example, a graph of Rgja versus drain pad area dxtasheet shown in Figures 1 datashet, 2 and 3. Find p F AV from Figure 6. All parts used in the soldering operation should be sampled on a lot by lot basis by assembly of a controlled sample.
It will study their main failure mechanisms and show the technological improvements that guarantee an enhanced ruggedness.
Rectification efficiency measurements show that operation will be satisfactory up to several megahertz. Various solder alloys can be used for this oper- ation but two types are recommended for best results: The failures always occur in the corners where the electric field is most critical.
The tape is used as the shipping container for various products and requires a minimum of datasehet. It is easy to verify that an energy rating is not the best approach to a ruggedness quantification because of avalanche energy fluctuations with test conditions. Cracked die inside the button may be observed by a moving reverse oscilloscope trace when pressure is applied to the unit.
To prevent bad joints and misalignment dafasheet is suggested that a weighting or spring loaded fixture be employed. All devices are connected cathode-to-case or cathode-to-heatsink, where applicable. An eight degree tilt is a suggested maximum value. Tighten each of the end bolts between 5 to 1 0 in-lb.
