| MR2535 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 Mechanical Characteristics http://onsemi.com * Case: Epoxy, Molded * Weight: 2.5 Grams (Approximately) * Finish: All External Surfaces Corrosion Resistant and Terminal * Maximum Lead Temperature for Soldering Purposes: * * 350C 3/8 from Case for 10 Seconds at 5 lbs.
