Overvoltage Transient Suppressor Designed for applications requiring a low voltage rectifier with reverse avalanche characteristics for use as reverse power transient suppressors.

1 Overvoltage Transient Suppressor 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. High Power Capability Economical Increased Capacity by Parallel Operation Mechanical Characteristics Case: Epoxy, Molded Weight: 2.
