Rectifier Device Data
Advance Information
Overvoltage
Transient Suppressors
. . . 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
Case: Epoxy, Molded
Weight: 2.5 grams (approximately)
Finish: All External Surfaces Corrosion Resistant and Terminal Leads are
Readily Solderable
Lead Temperature for Soldering Purposes: 260
C Max. for 10 Seconds
Polarity: cathode polarity band
MR2535L shipped 1000 units per plastic bag. Available Tape and Reeled,
800 units per reel by adding a "RL" suffix to the part number.
MR2535S shipped pocket tape and reeled, 500 per 13
reel
