BT131-800,116

Overview

The BT131-800,116 is a standard four-layer bidirectional triac manufactured by WeEn Semiconductors. It features an RMS on-state current of 1 A and a non-repetitive peak on-state current of 13.8 A. The device supports a rated repetitive peak off-state voltage (VDRM) of 800 V with a maximum off-state leakage current of 100 uA at VDRM. Key gate parameters include a maximum holding current of 5 mA, a gate trigger voltage of 700 mV, and a gate trigger current of 3.8 mA. The component operates within a temperature range of -40°C to +125°C and utilizes a through-hole TO-92-3 package.

Feature Summary

• Standard four-layer bidirectional triac structure for AC switching applications
• High thermal stability supporting operation up to +125°C junction temperature
• Robust gate triggering characteristics with defined voltage and current thresholds

Applications

• Lighting control systems requiring low-power AC regulation
• Solid-state relays for general-purpose switching
• Motor speed control circuits for small appliances

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and compliance status. Ensure that the requested part number matches the exact electrical ratings required for the target circuit design. Cross-reference the manufacturer's latest datasheet to confirm availability and any potential product change notifications affecting the component specifications.

Selection Notes

Select this component when a 1 A RMS current rating and 800 V blocking voltage are sufficient for the application. Consider the TO-92-3 package constraints regarding thermal dissipation and mounting requirements. Evaluate the gate trigger current of 3.8 mA to ensure compatibility with the driving circuitry capabilities without exceeding maximum ratings.

Part Context

This component belongs to the BT131 series of standard triacs from WeEn Semiconductors. The series offers various voltage ratings, with the 800 variant providing higher blocking capability compared to lower voltage options like the 600 V version. The '116' suffix typically denotes a specific tape-and-reel packaging configuration used in high-volume manufacturing environments.

Replacement Considerations

Compatible substitutes include other 1 A, 800 V standard triacs in TO-92 packages such as the BT131-800E/L01EP. Verify pinout compatibility and thermal characteristics before substitution.
