BTA316-800B,127

Triacs Overview

The BTA316-800B,127 is a planar passivated high commutation three quadrant triac manufactured by WeEn Semiconductors. It is housed in a TO-220 plastic package and designed for circuits experiencing high static and dynamic dV/dt and high dI/dt. The device supports an RMS current of 16 A with a peak non-repetitive on-state current of 140 A. It features a rated repetitive off-state voltage of 800 V and a maximum junction temperature of 125°C. Key electrical parameters include a gate trigger voltage of 800 mV, a holding current of 15 mA, and an on-state voltage of 1.3 V.

Triacs Feature Summary

• Planar passivated construction ensures robust performance under high commutation conditions.
• Three quadrant operation provides reliable switching capabilities across multiple operating modes.
• High dV/dt immunity reduces the risk of false triggering in noisy environments.

Triacs Applications

• Industrial motor control systems requiring high commutation reliability
• Solid state relays operating under high dv/dt stress
• General purpose AC power switching applications

Triacs Procurement Notes

Verify the specific ordering suffix to confirm the package type and packing configuration. The BTA316-800B,127 designation corresponds to the TO-220 package variant. Confirm RoHS compliance and lead-free status through official manufacturer documentation before procurement. Ensure the selected part matches the required thermal and electrical specifications for the target application.

Triacs Selection Notes

Select this component when a TO-220 packaged triac with 800 V blocking capability and 16 A RMS current rating is required. Consider the 125°C maximum junction temperature limit for thermal management design. Evaluate the need for snubberless operation at maximum temperatures, as specified for this series. Compare against other packages like D2PAK if surface mount solutions are preferred.

Triacs Part Context

This component belongs to the BTA316 series of high commutation triacs from WeEn Semiconductors. The series includes variants with different voltage ratings and packaging options. The BTA316-800B specifically denotes the 800 V version in the 'Series B' configuration, which offers improved commutation characteristics compared to standard devices.

Triacs Replacement Considerations

Direct substitutes within the same family include BTA316-800ET,127 and BTA316-800B0,127. Verify pinout compatibility and thermal resistance differences when replacing components. Cross-reference datasheets to ensure equivalent electrical parameters and package dimensions for seamless integration.
