The HRP2540 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.
The HRP2540 is a high forward current, high reverse energy controlled avalanche power rectifier designed for automotive alternator systems. It provides load dump suppression and transient protection for accessories. The device features a low forward voltage drop (1.1V max at 100A) and controlled maximum avalanche voltage (40V max at 40A). It is packaged in a JEDEC TO-220AB case and includes electrical specifications, performance curves, and mounting hardware suggestions.
| Forward Voltage Drop | 1.1V Max at 100A |
|---|---|
| Reverse Current at 20V | 1 mA |
| Breakdown Voltage | 24 to 32 V |
| Thermal Resistance | 1.25 °C/W |
The maximum forward voltage drop is 1.1V at 100A.
The controlled maximum avalanche voltage is 40V max at 40A.
The package type is JEDEC TO-220AB.
