BTA316X-800B/L02Q

Triacs Overview

The BTA316X-800B/L02Q is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in a TO-220F-3 (SOT-78) through-hole package. The device features an RMS on-state current of 16 A and a non-repetitive peak on-state current of 140 A. It supports a rated repetitive off-state voltage of 800 V with a maximum junction temperature of +150°C. Key electrical parameters include a gate trigger voltage of 800 mV, gate trigger current of 10 mA, and holding current of 15 mA.

Triacs Feature Summary

• High commutation capability designed for circuits experiencing high static and dynamic dV/dt and dI/dt conditions.
• Capable of commutating full RMS current at the maximum rated junction temperature without requiring external snubber circuits.
• Three-quadrant triggering functionality ensures reliable operation across various gate signal polarities.

Triacs Applications

• Industrial motor control systems
• Solid-state relays
• Lighting dimmer applications

Triacs Procurement Notes

Verify the specific suffix /L02Q against official manufacturer documentation to confirm exact packaging and tape-and-reel specifications. Confirm RoHS compliance status and lead-free conversion dates directly from the datasheet before procurement. Ensure the ordering part number matches the required thermal and mechanical characteristics for the target application.

Triacs Selection Notes

Select this component when high dV/dt immunity and snubberless operation are required in high-power AC switching environments. Compare the 16 A RMS rating and 800 V blocking voltage against circuit load requirements. Verify that the TO-220F-3 package provides adequate thermal dissipation for the intended duty cycle and ambient temperature conditions.

Triacs Part Context

This triac belongs to the BTA316 series, which includes variants such as BTA316-800ET and BTA316-800C. These devices share similar core electrical ratings but differ in packaging styles and specific commercial suffixes. The BTA316X variant specifically denotes the TO-220F-3 form factor within the broader product family.

Triacs Replacement Considerations

Potential substitutes include the BTA316-800ET,127 or BTA316-800C/L03Q. Verify pinout compatibility and thermal resistance values before substitution. Ensure the alternative part meets the same 800 V and 16 A specifications.
