Power supply voltage transients, or device output short circuits,

may be caused by faulty connectors, crimped wiring harnesses, or

service errors. To prevent catastrophic failure, internal protection

against overvoltage, reverse voltage, output overloads, and thermal

stress have been incorporated to meet the automotive 12 volt system

protection requirements of ISO DP7637/1 and DIN 40839-1. A series-

blocking diode or current-limiting resistor is required in order to

survive pulse number six.
