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 for-
ward voltage clamping and reverse voltage bypassing. This
will protect the accessory from L-C inductive spikes and/or
field decay transients.
