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.
Features
* Low Forward Voltage Drop (1.1V Max at 100A) * High Reverse Energy Capability * Controlled Maximum Avalanche Voltage (40V Max at 40A)
Applications
* Alternator Rectification * Accessory Load Dump Protector * High Current Forward Voltage Clamp
