产品信息

The internal short of a high voltage power semiconductor can cause the misconnection of the rail voltage to the driver circuit resulting in catastrophic damage to the driver circuit. Caddock's ultra-fast Fault Current Fusing Resistor technology reacts to the sudden fault quickly interrupting the high current, high voltage fault.

Caddock's ultra-fast Fault Current Fusing Resistors include:

• Ultra-fast fusing of sudden fault events, typically less that 20µsec.
• Voltage rating of 200 volts dc (higher voltage capability is available)
• Resistive fuse element of 1 ohm up to 30 ohm
• Normal continuous operating current of up to 1 amp

Caddock's ultra-fast Fault Current Fusing Resistor technology is intended to provide a quick opening (fusing action) to sudden fault current events that suddenly cause at least the fault voltage to appear across the device while not exceeding the maximum fault voltage. Other fusing devices or protection consideration must be provided by the circuit designer for electrical faults other than the specific sudden fault current protection that this device provides.

Patents pending

Please contact Caddock applications engineering to evaluate the use of Caddock's ultra-fast Fault Current Fusing Resistor technology in your power driver circuits.
