BTA203-800ETQP

Triacs Overview

The BTA203-800ETQP is a bidirectional triac manufactured by WeEn Semiconductors, designed for general-purpose AC power control applications. It features an RMS on-state current of 3 A and a non-repetitive peak on-state current of 60 A. The device supports a rated repetitive off-state voltage (VDRM) of 800 V with a maximum on-state voltage of 1.3 V. Gate trigger parameters include a maximum holding current of 50 mA and a gate trigger current of 10 mA. It operates within a junction temperature range of -40°C to +150°C and utilizes a TO-92-3 through-hole package.

Triacs Feature Summary

• Snubberless design capability for simplified circuit implementation
• High commutation performance suitable for inductive loads
• Planar passivated construction for enhanced reliability

Triacs Applications

• Lighting dimmers
• Motor speed controls
• General purpose AC switching

Triacs Procurement Notes

Verify the specific suffix 'Q' indicates tape and reel packaging when sourcing from distributors. Confirm RoHS compliance status directly with the manufacturer or authorized suppliers prior to finalizing procurement orders. Ensure the selected distributor provides valid traceability documentation for the component batch.

Triacs Selection Notes

Select this component for low-power AC regulation tasks requiring robust dv/dt immunity. The TO-92-3 package limits thermal dissipation compared to larger packages; ensure adequate heatsinking or derating is applied if operating near the 3 A RMS limit. Verify that the 800 V blocking voltage meets the peak line voltage requirements of the target application circuit.

Triacs Part Context

This part belongs to the BTA series of high-commutation triacs from WeEn Semiconductors. It shares architectural similarities with other planar passivated devices in the lineup but distinguishes itself through its compact TO-92-3 form factor. The series is engineered to provide reliable switching in consumer electronics and industrial control environments where space constraints are significant.

Triacs Replacement Considerations

Direct substitutes may include the BTA203-800ET variant, though packaging differences exist. Cross-reference electrical parameters such as VDRM, IT(RMS), and package dimensions with alternative manufacturers like STMicroelectronics or ON Semiconductor before integration.
