HRP2540

HRP2540 April 1995 File Number 2942.1 Power Rectifier/Power Surge Suppressor The HRP2540 (TA9673) is a high forward current, high reverse energy controlled avalanche power rectifier. It uses an ion-implanted planar epitaxial construction. This device was designed for use as the output rectifier in the three phase six diode bridge assembly of an automotive alternator system. It provides “Load Dump” suppression by virtue of its precisely controlled reverse avalanche breakdown voltage. When used singly it can also serve as a transient suppressor for an automotive accessory. This device can provide forward voltage clamping and reverse voltage bypassing. This will protect the accessory from L-C inductive spikes and/or field decay transients.
