BTA204W-800E,135

Triacs Overview

The BTA204W-800E,135 is a planar passivated three-quadrant triac manufactured by WeEn Semiconductors. It operates with an RMS on-state current of 1 A and supports a non-repetitive peak on-state current of 10 A. The device features a rated repetitive off-state voltage (VDRM) of 800 V and maintains a maximum junction temperature of +125 °C. Gate sensitivity is optimized for low-power drivers, with a maximum gate trigger current of 10 mA across quadrants Q1, Q2, and Q3. It is housed in a SOT223 surface-mount package and supplied in a Reel 11¼" LargePack configuration.

Triacs Feature Summary

• Planar passivated construction ensures high commutation reliability in three-quadrant operation.
• Balanced design optimizes the trade-off between commutation performance and gate sensitivity.
• Surface-mountable SOT223 plastic package facilitates automated assembly processes.

Triacs Applications

• Motor control circuits
• Highly inductive load switching
• Interfaces with low power drivers and microcontrollers

Triacs Selection Notes

Select this component when a surface-mount solution is required for low-current AC switching applications. The SOT223 package suits space-constrained designs. Ensure the driving circuit can supply the specified 10 mA gate trigger current to guarantee reliable turn-on across all operating quadrants at maximum temperatures.

Triacs Part Context

This part belongs to the BTA204W series of planar passivated triacs from WeEn Semiconductors. The series is engineered for industrial applications requiring robust commutation characteristics. The 'W' designation indicates the SOT223 surface-mount package variant, distinguishing it from through-hole options like the TO-220AB or TO-220F packages found in other series members.

Triacs Replacement Considerations

Direct pin-compatible replacements within the same manufacturer family include the BTA204W-600C,135 for lower voltage requirements. Cross-manufacturer equivalents should be evaluated based on matching the 1 A RMS current, 800 V blocking voltage, and SOT223 footprint constraints.
