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.

Features

•Avalanche Voltage 24 to 32 V

•High Power Capability

•Economical

•Increased Capacity by Parallel Operation

•Pb−Free Packages are Available*

Mechanical Characteristics:

•Case: Epoxy, Molded

•Weight: 2.5 Grams (Approximately)

•Finish: All External Surfaces Corrosion Resistant and Terminal

Leads are Readily Solderable

•Maximum Lead Temperature for Soldering Purposes:

350°C 3/8″ from Case for 10 Seconds at 5 lbs. Tension

•Polarity: Indicated by Diode Symbol or Cathode Band
