BTA25H-800CW3G

Triacs Overview

The BTA25H-800CW3G is a high-power Triac manufactured by Littelfuse, designed for robust AC power control applications. It features an RMS on-state current (It RMS) of 25 A and a non-repetitive peak on-state current of 250 A. The device supports a rated repetitive peak off-state voltage (VDRM) of 800 V with a maximum off-state leakage current of 5 uA at VDRM. Key electrical parameters include an on-state voltage of 1.55 V, a maximum holding current (Ih) of 50 mA, a gate trigger voltage (Vgt) of 1.7 V, and a gate trigger current (Igt) of 50 mA. It operates within a temperature range of -40°C to +150°C and utilizes a TO-220-3 package for through-hole mounting.

Triacs Feature Summary

• High thermal stability with a maximum junction temperature rating of 150°C
• Robust surge handling capability with a 250 A non-repetitive peak current rating
• Low leakage current ensures reliable blocking performance in the off-state

Triacs Applications

• Industrial motor speed control systems
• Solid-state relays for high-power switching
• AC power regulation circuits

Triacs Procurement Notes

Verify the specific part number suffix against official Littelfuse documentation to confirm the exact voltage rating and packaging configuration. Ensure that the procurement channel provides valid traceability and authenticity certificates for semiconductor components. Cross-reference the manufacturer's latest datasheet to confirm compliance with current RoHS and REACH standards before finalizing orders.

Triacs Selection Notes

Select this component when an application requires a 25 A RMS current capacity with an 800 V blocking voltage. Verify that the gate drive circuit can supply the specified 50 mA trigger current. Confirm that the thermal management design accommodates the 1.55 V on-state voltage drop at full load. Ensure the operating environment remains within the specified -40°C to +150°C temperature range.

Triacs Part Context

This Triac belongs to the BTA25H series from Littelfuse, which is engineered for demanding industrial power control tasks. The H-series typically denotes enhanced ruggedness and thermal performance compared to standard variants. The CW3G suffix indicates specific lead-free and halogen-free compliance attributes defined by the manufacturer.

Triacs Replacement Considerations

Direct replacements must match the 25 A RMS current, 800 V voltage rating, and TO-220-3 package. Verify equivalent gate trigger characteristics and thermal resistance values. Consult Littelfuse or authorized distributors for validated cross-reference data.
