MR2835SK Overvoltage Transient Suppressor The overvoltage transient suppressor is designed for applications requiring a diode with reverse avalanche characteristics for use as reverse power transient suppressor. Developed to suppress transients in the automotive system, this device operates in reverse mode as power zener diode and will protect expensive modules such as ignition, injection and autoblocking systems from overvoltage conditions. http://onsemi.com MARKING DIAGRAM Cathode Features • High Power Capability • Economical • This is a Pb−Free Device TOP CAN BUTTON CASE 460 LLA MR2835S Y WW G Mechanical Characteristics • • • • Finish: All External Surfaces are Corrosion Resistant Polarity: Cathode to Terminal Weight: 1.78 Grams (Approximately) Maximum Temperature for Soldering Purposes: 260°C for 10 s using a Belt Furnace MAXIMUM RATINGS Symbol Value Unit VR 23 V Peak Repetitive Reverse Surge Current (Time Constant = 10 ms, TC = 25°C) IRSM 62 A Non−Repetitive Peak Surge Current (Half−wave, Single Phase, 50 Hz) IFSM 400 A Storage Temperature Range Tstg −40 to +150 °C Operating Junction Temperature Range TJ −40 to +150 °C Characteristic Symbol Value Unit Thermal Resistance, Junction−to−Case RqJC 1.0 °C/W DC Blocking Voltage = Lot Number = Specific Device Code = Year = Work Week = Pb−Free Package ORDERING INFORMATION Device Rating LLA MR2835S YWWG Package Shipping† MR2835SK Top Can Button* 500/Tape & Reel MR2835SKG Top Can Button* 500/Tape & Reel †For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D. *This package is inherently Pb−Free.
