Rectifier Device Data
. . . 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.
