BTA316B-800E,118

Triacs Overview

The BTA316B-800E,118 is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It operates in a TO263 (D2PAK) surface-mount package with an RMS on-state current of 16 A and a non-repetitive peak on-state current of 140 A. The device supports a rated repetitive peak off-state voltage of 800 V and features a maximum junction temperature of 125°C. Gate trigger currents are limited to 10 mA across all quadrants, while the dV/dt rating reaches 60 V/µs.

Triacs Feature Summary

• High commutation capability allows full RMS current commutation at maximum rated junction temperature without snubber circuits.
• Sensitive gate design facilitates direct interfacing with low-power drivers and microcontrollers.
• Planar passivation technology ensures robust performance under high static and dynamic dV/dt conditions.

Triacs Applications

• Industrial motor control systems
• Solid-state relays
• Lighting dimmers

Triacs Procurement Notes

Verify the specific suffix '118' corresponds to the reel packing configuration on Q1/T1 as documented in official manufacturer ordering lists. Confirm RoHS compliance status and lead-free plating specifications against the latest chemical content reports provided by WeEn Semiconductors for this exact part number.

Triacs Selection Notes

Select this component when high commutation performance is required alongside sensitive gate drive compatibility. Ensure the application environment remains within the 125°C maximum junction temperature limit. Verify that the 800 V blocking voltage and 16 A RMS current ratings adequately cover the circuit's operational peaks and steady-state requirements.

Triacs Part Context

This device belongs to the BTA316 series of high commutation triacs from WeEn Semiconductors. The 'Series E' designation indicates a balance between commutation performance and gate sensitivity. It serves as a surface-mount alternative to through-hole variants like the BTA316-800ET, offering similar electrical characteristics in a D2PAK form factor.

Triacs Replacement Considerations

Direct functional substitutes include other Series E triacs from the same family, such as the BTA312B-800E,118, which shares identical packaging and gate sensitivity but offers a lower 12 A RMS current rating. Cross-brand replacements require matching the 800 V voltage class, 16 A current capacity, and TO263 package dimensions.
