Description

Product Overview

The Vishay SS24-E3/57T is a 2A, 20V Schottky rectifier diode in SMA (DO-214AC) package. With a low 0.5V forward voltage drop at 2A, it is designed for low-voltage high-efficiency rectification, freewheeling, and reverse protection in battery-powered devices and DC-DC converters.

Key Specifications

Type Schottky Rectifier
Reverse Voltage 20V
Average Forward Current 2A
Forward Voltage 0.5V @ 2A (typical)
Reverse Current 2uA @ 20V (typical)
Peak Forward Surge 50A (8.3ms)
Operating Temperature -65°C to +150°C (Tj)
Package SMA (DO-214AC)

Features

  • Low 0.5V forward voltage for high efficiency
  • 20V for single-cell Li-ion systems
  • 2A in compact SMA package
  • Zero reverse recovery time
  • Guard ring for overvoltage protection
  • RoHS compliant

Applications

  • Single-cell Li-ion DC-DC freewheeling
  • Reverse battery protection
  • 5V power supply OR-ing
  • Low-voltage rectification
  • Portable device power routing

The Vishay SS24-E3/57T is a 2A 20V Schottky rectifier in SMA package with 0.5V typical forward voltage at 2A. The 20V rating is optimized for single-cell Li-ion (3.0-4.2V) and 5V systems. The low forward voltage drop significantly reduces power dissipation in DC-DC converter freewheeling and reverse protection applications, improving overall system efficiency.

The SS24-E3/57T uses a metal-silicon Schottky barrier junction providing low forward voltage (0.5V) and zero reverse recovery time. The 20V rating is the lowest in the SS2x series, providing the lowest forward voltage for single-cell battery applications where voltage margin is limited. The Schottky barrier eliminates minority carrier storage, enabling very fast switching with no reverse recovery current spike.
