Abstract
A protection device for a Schottky diode is described. The protection device has a cascade circuit with at least two Si-PIN diodes provided parallel to the Schottky diode. The protection device protects against momentary over-current pulses reliably and without a high outlay in terms of cost and necessary materials for forming the protection device.
Claims10
A configuration having protection against momentary over-current pulses, comprising:
- a Schottky diode;
- and
- a series circuit containing at least two diodes, selected from the group consisting of Si-PIN diodes and Si-PN diodes, disposed in parallel with said Schottky diode, said Schottky diode being produced from a semiconductor material having a band gap greater than a band gap of silicon.
