SANREX SEMI-PAK – SBAU-33C – SUM11P055 – IGBT Power Transistor – Reclaimed Part

SanRex Semi-PAK — SBAU-33C (SUM11P055) Thyristor Power Module • Industrial Phase-Control Semiconductor Module • Heatsink-Mounted Package

What it is

The SanRex Semi-PAK SBAU-33C, associated with drawing or assembly reference SUM11P055, is a legacy industrial thyristor power module designed for high-power switching and phase-control applications. This style of SanRex semiconductor module was used in rectifier, AC power-control, motor-control, heater-control and other industrial power-conversion equipment.

The module uses a compact heatsink-mounted power-semiconductor package intended for service in high-current industrial assemblies. Because SBAU-33C / SUM11P055 documentation is limited, electrical ratings should be verified against the original equipment documentation or module markings before replacement or substitution.
