A standard thermal calculation shows that: These failures are essentially function of the thermal characteristics of the device when conducting avalanche currents. Power Dissipation Mounting method datsaheet per note 1. An analysis of the standard UIS test circuit has shown the limits of a charac- terization based on energy ratings.

The non-preferred devices will continue to be offered, but customers are encouraged to begin designing using the preferred types. Profiling must be performed on a scheduled basis to minimize poor soldering. However, in contrast to ordinary junction diodes, the loss in waveform efficiency is not indicate of power loss; it is simply a result of reverse current flow through the diode capacitance, which lowers the dc out- put voltage.

Find p F AV from Figure byww80. These can vary from the minimum pad size for soldering to a pad size given for maximum power dissipation. For example, rel- ative waveform rectification efficiency is approximatley 70 per- cent at 2 MHz, e.

Table 1 indicates suggested factors for an equivalent dc voltage to use for conservative design, that is: Find VR equ j V. For a given total lead length, lowest values occur when one side of the rectifier is brought as close as possible to the heatsink. Thermal Clad is a trademark of the Bergquist Company. The necessity for avalanche rugged power semiconduc- tors has clearly been perceived by many semiconductor manufacturers who have come up with avalanche-energy rated devices.


Typical reverse current Lever Pull lbs max 50 lbs max Note: The top copper lead has a stress relief feature which protects the die during assembly. For heat conduction through bjw80 leads Use of the above model permits junction to lead thermal re- sistance for any mounting configuration to be found.

Using a board material such as Thermal Clad, an aluminum core board, the power dissipation can be doubled using the same footprint. Daatasheet products can be acceptable for new designs but the preferred types are considered better alternatives for long term usage.

These rectifiers have very low breakdown voltages and therefore very thin epitaxy layers. Aq, Bq, and Kg are determined by component size. Although it is not recommended to design for this condition, the new “E” 510 provides added protec- tion against those unforeseen transient viruses that can produce unexplained random failures in unfriendly environments.

The Safe Avalanching Area is generated by taking a safety margin from the failure points. There are other alternatives to achieving higher power dissipation bwy80 the surface mount packages. To avoid unnecessary breakdown voltage guardbands, new generations of semiconductors are now avalanche rugged and characterized in avalanche energy.


While analyzing different constant current test circuits, it appeared that devices used in a floating configuration can have very poor avalanche capabilities. There are handling problems because of slow cooling. 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 bar- rier.

Different test circuits datasyeet to figure 9 have been pro- posed by Gauen 1 and Pshaenich 2. The failure analysis proves that the main cause of degradation is the in- datasjeet to handle an excessive power avalanche current Ir multiplied by breakdown voltage BVr.

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 may occur.

Throughout a discussion of the main failure mechanisms, a new thermal approach has been proposed to help designers set safety levels in their de- signs.

Solder flow and positioning can be cor- rected during soldering since the assembly is exposed. Preferred devices are Motorola recommended choices for future use and best overall value.
