Power Recti鏗乪r/Power Surge Suppressor
The HRP2540 (TA9673) is a high forward current, high
reverse energy controlled avalanche power recti鏗乪r. It uses
an ion-implanted planar epitaxial construction. This device
was designed for use as the output recti鏗乪r in the three
phase six diode bridge assembly of an automotive alternator
system. It provides 鈥淟oad Dump鈥?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
鏗乪ld decay transients.
Features
鈥?Low Forward Voltage Drop (1.1V Max at 100A)
鈥?High Reverse Energy Capability
鈥?Controlled Maximum Avalanche Voltage (40V Max at 40A)
Applications
鈥?Alternator Recti鏗乧ation
鈥?Accessory Load Dump Protector
鈥?High Current Forward Voltage Clamp
