TM2541B-L

Overview

The TM2541B-L is a TO-3PF package TRIAC manufactured by Sanken Electric USA Inc. It features a maximum repetitive peak off-state voltage of 400 V and an RMS on-state current rating of 25 A. The device has a maximum gate trigger voltage of 2 V and supports non-repetitive surge currents at 50 Hz and 60 Hz frequencies.

Feature Summary

• High current handling capability with 25 A RMS on-state rating
• Robust voltage blocking performance up to 400 V in the off state
• Standardized TO-3PF through-hole packaging for thermal management

Applications

• Industrial motor control systems
• Resistive load switching applications
• Power regulation circuits requiring high current capacity

Procurement Notes

Verify the specific datasheet revision and manufacturer documentation to confirm electrical characteristics match design requirements. Ensure the TO-3PF mounting configuration aligns with the target PCB or heatsink interface. Cross-reference the part number with official Sanken Electric catalogs to validate availability and authenticity before finalizing supply chain agreements.

Selection Notes

Select this component when circuit designs require a 400 V rated TRIAC capable of sustaining 25 A continuous current. The TO-3PF package is suitable for applications needing robust mechanical stability and efficient heat dissipation. Evaluate gate trigger parameters against the driving circuit capabilities to ensure reliable turn-on under all operating conditions.

Part Context

This TRIAC belongs to Sanken's discrete power semiconductor lineup, designed for industrial and commercial power electronics. The TO-3PF form factor distinguishes it from smaller surface-mount alternatives, offering higher thermal mass. It serves as a core switching element in AC power control architectures where durability and high current throughput are critical operational priorities.

Replacement Considerations

Consult official substitution guides for equivalent TRIACs with matching 400 V ratings and 25 A current capacities. Verify pinout compatibility and thermal resistance specifications to ensure seamless integration without redesigning the cooling infrastructure or PCB layout.
