Toshiba — S5977 Power Semiconductor Module • Industrial Power Electronics • Heatsink-Mount Package • Reclaimed Component
What it is

The Toshiba S5977 is a legacy high-power semiconductor module designed for industrial power-electronics equipment. The module uses a heavy-duty insulated package with large power terminals, separate control connections and a metal mounting base designed for direct installation to a heatsink.

This reclaimed S5977 is intended primarily for maintenance and repair of legacy equipment originally designed around this Toshiba module. Because detailed factory specifications for the S5977 are not readily available, electrical ratings and internal semiconductor configuration should be verified against the original equipment documentation before installation or substitution.

At-a-Glance
  • Manufacturer: Toshiba
  • Part Number: S5977
  • Component Class: High-power semiconductor module
  • Construction: Heavy-duty industrial power-module package
