BTA202W-800ETF

Triacs Overview

The BTA202W-800ETF is a planar passivated three-quadrant triac manufactured by WeEn Semiconductors. It is housed in a SOT223 surface-mountable plastic package designed for motor control circuits and highly inductive loads. The device balances commutation performance with gate sensitivity, making it suitable for low-power drivers including microcontrollers. Key electrical parameters include an 800 V repetitive peak off-state voltage (VRRM/VDRM), a 2 A RMS on-state current (IT(RMS)), and a 25 A non-repetitive peak on-state surge current (ITSM). The maximum gate trigger current is 10 mA across quadrants Q1, Q2, and Q3, with a dV/dt rating of 500 V/µs and a maximum junction temperature of 150°C.

Triacs Feature Summary

• Planar passivated construction ensures voltage ruggedness and reliability
• Three-quadrant guaranteed commutation capability
• Optimized balance between commutation performance and gate sensitivity
• Surface mountable SOT223 plastic package design

Triacs Applications

• Motor control circuits
• Highly inductive load switching
• Interfacing with low power drivers
• Microcontroller-based logic IC applications

Triacs Procurement Notes

Verify the specific suffix 'F' against the manufacturer's official documentation to confirm reel packaging specifications and marking standards. Ensure compatibility with SOT223 footprint requirements during PCB layout. Confirm industrial qualification status and RoHS compliance through the latest datasheet revision before finalizing procurement orders.

Triacs Selection Notes

Select this component when a surface-mount solution is required for inductive loads. The three-quadrant operation simplifies gate drive circuitry compared to four-quadrant devices. Verify that the 2 A RMS current rating meets the application's continuous load requirements. Check that the 800 V blocking voltage exceeds the peak line voltage plus transients.

Triacs Part Context

This part belongs to the BTA202W series of high-voltage triacs from WeEn Semiconductors. It shares the same core die and electrical characteristics as the BTA202W-800ET but utilizes the 'F' suffix to denote specific tape-and-reel packaging for automated surface-mount assembly processes within the SOT223 form factor.

Triacs Replacement Considerations

Direct pin-compatible replacements within the same package must maintain the 800 V rating and 2 A current capacity. Verify that any substitute also offers three-quadrant commutation if the original gate drive circuit relies on this characteristic. Cross-reference thermal resistance values to ensure adequate heat dissipation in the SOT223 package.
