Overvoltage
Transient Suppressors
Medium Current
Designed for applications requiring a low voltage rectifier with
reverse avalanche characteristics for use as reverse power transient
suppressors. Developed to suppress transients in the automotive
system, these devices operate in the forward mode as standard
rectifiers or reverse mode as power avalanche rectifier and will protect
electronic equipment from overvoltage conditions.
• Avalanche Voltage 24 to 32 Volts
• High Power Capability
• Economical
• Increased Capacity by Parallel Operation
