Discrete Semiconductor Products

Schottky rectifierDual diodeCommon cathode30 VD2PAK40 A

A 30 V dual common-cathode Schottky rectifier in D2PAK, designed for low forward drop and up to 20 A average current per leg.

Best for

  • Low-voltage switching power supply rectification
  • Freewheeling paths
  • Reverse-battery protection

Avoid if

  • Reverse voltage can exceed 30 V including transients
  • High-temperature leakage is unacceptable
  • Thermal path from D2PAK is insufficient

Check before use

  • Per-leg average and peak current
  • Reverse-voltage transient margin
  • Junction temperature and heatsinking
  • Common-cathode pinout and tab connection
