Triacs datasheet and documents for BTA25-600B
Triacs Overview
The BTA25-600B is a 25 A, 600 V bidirectional thyristor (Triac) manufactured by STMicroelectronics. It utilizes the Snubberless™ technology for high commutation capability in four-quadrant triggering modes. The device is housed in an RD-91 panel-mount package with three terminals. Key electrical parameters include a maximum on-state voltage of 1.55 V, a peak non-repetitive surge current rating of 260 A, and a maximum holding current of 80 mA. It operates within a junction temperature range of -40°C to +125°C.
Triacs Feature Summary
- Snubberless design enabling direct control of inductive loads without external RC snubber networks
- High commutation capability supporting reliable switching across all four quadrants of gate triggering
- Low thermal resistance construction utilizing clip bonding for efficient heat dissipation
Triacs Applications
- General purpose mains power AC switching circuits
- Solid state relays and industrial motor controls
- Lighting dimmers and heating element regulation
Triacs Procurement Notes
Verify the specific suffix against official STMicroelectronics documentation to confirm exact electrical tolerances and packaging variations. Confirm RoHS compliance status and UL certification file references prior to integration into safety-critical designs.
Triacs Selection Notes
Select this component for applications requiring robust handling of inductive load currents and high surge tolerance. Ensure the RD-91 panel mount form factor aligns with available heatsinking infrastructure and enclosure constraints.
Triacs Part Context
This Triac belongs to the BTA series designed for general-purpose AC power control. It shares core Snubberless architecture with siblings like the BTA24 and BTA26, differentiated primarily by package type and specific current ratings.
Triacs Replacement Considerations
Direct functional substitutes within the same family include BTA25-600BW or BTA25-800B. Verify pinout compatibility and thermal characteristics when replacing with equivalent devices from other manufacturers.
