Description

Product Overview

The SSC54-E3 from Vishay is a 5A, 40V Schottky rectifier diode in an SMC (DO-214AB) package. With a low forward voltage drop of 0.55V at 5A and 150A surge current rating, it is designed for high-frequency rectification and freewheeling in switching power supplies.

Operating Temperature -65°C to +150°C
Package SMC (DO-214AB)

Features

  • Low 0.55V forward voltage for high rectification efficiency
  • 5A continuous current rating with 150A surge capability
  • SMC (DO-214AB) surface-mount package for automated assembly
  • Guard-ring structure for ruggedness and ESD protection
  • Low junction capacitance (200pF) for high-frequency operation
  • Halogen-free and RoHS compliant

Applications

  • DC-DC converter output rectification
  • Freewheeling diode in motor drive circuits
  • Reverse polarity protection in power supplies
  • Battery charging and OR-ing diode circuits

The SSC54-E3 from Vishay is a 5A, 40V Schottky rectifier diode in a surface-mount SMC (DO-214AB) package. Its low 0.55V forward voltage drop at rated current minimizes power dissipation in rectification and freewheeling applications. The 150A non-repetitive surge current rating provides robustness against transient overloads, while the guard-ring structure enhances reliability under harsh electrical conditions. The 200pF junction capacitance supports efficient high-frequency operation in switching power supply output stages.

The SSC54-E3 is a metal-silicon Schottky junction rectifier. Unlike conventional PN junction diodes, the Schottky barrier is formed by the contact between a metal (typically molybdenum or chromium) and N-type silicon. This structure eliminates minority carrier storage, resulting in negligible reverse recovery time and low forward voltage drop (0.55V vs. 0.7-1.0V for silicon PN diodes). When forward-biased, majority carriers (electrons) flow from the semiconductor into the metal with minimal energy loss. The guard-ring structure around the main junction prevents edge breakdown and enhances ESD tolerance. The low junction capacitance (200pF) ensures minimal charge storage at high switching frequencies.
