TRA2532
Overvoltage
Transient Suppressor
24 V–32 V
Designed for applications requiring a diode with reverse avalanche
characteristics for use as reverse power transient suppressor.
Developed to suppress transients in automotive system, this device
operates in the forward mode as standard rectifier or reverse mode as
power zener diode and will protect expensive modules such as
ignition, injection, antiblocking system . . . from overvoltage conditions.
