BTA208S-800F,118

Triacs Overview

The BTA208S-800F,118 is a planar passivated high commutation three quadrant triac manufactured by WeEn Semiconductors. It is housed in a SOT428 (DPAK) surface mountable plastic package, specifically TO252. The device features an RMS current rating of 8 A and a non-repetitive peak on-state current of 65 A. It supports a rated repetitive peak off-state voltage of 800 V with a maximum junction temperature of 125 °C. Gate trigger current is limited to 25 mA across quadrants Q1, Q2, and Q3. The component exhibits a static dV/dt rating of 70 V/µs and is qualified for industrial applications.

Triacs Feature Summary

• Balances commutation performance and gate sensitivity for interfacing with low power drivers and logic ICs including microcontrollers in higher noise environments.

Triacs Applications

• Interfacing with low power drivers
• Logic IC connections
• Microcontroller circuits in higher noise environments

Triacs Procurement Notes

Verify the complete orderable part number includes the suffix ,118 to ensure correct reel packaging configuration. Confirm RoHS compliance and lead-free plating status through official chemical content documentation. Check for recent product change notifications regarding manufacturing updates or material substitutions before finalizing procurement specifications.

Triacs Selection Notes

Select this component when high commutation capability is required alongside moderate gate sensitivity for noise immunity. Ensure the application environment does not exceed the 125 °C maximum junction temperature limit. Verify that the circuit design accommodates the 70 V/µs dV/dt rating without additional snubber networks if operating near maximum ratings.

Triacs Part Context

This triac belongs to the BTA208S series from WeEn Semiconductors, designed for surface mount applications. The 'Series F' designation indicates specific gate sensitivity characteristics optimized for balancing commutation performance with noise immunity in industrial settings.

Triacs Replacement Considerations

Direct substitutes within the same family include BTA208S-800B,118 for higher dV/dt tolerance, or BTA208S-600BT,118 for lower voltage requirements. Cross-package replacements require verifying pinout compatibility and thermal management differences between DPAK and alternative packages.

Triacs FAQ

What is the maximum gate trigger current for the BTA208S-800F?

The maximum gate trigger current is 25 mA for all quadrants (Q1, Q2, and Q3).

Does the BTA208S-800F require a snubber network for commutation?

The datasheet description highlights its high commutation performance but does not explicitly state it operates without a snubber at full RMS current like Series B; verification against the specific electrical characteristics table is recommended for critical designs.

What is the static dV/dt rating for this component?

The static dV/dt rating is 70 V/µs.
