BTA201-800ER,116

Triacs Overview

The BTA201-800ER,116 is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in an SOT54 (TO-92) plastic package and designed for interface with low-power drivers such as microcontrollers and logic ICs. The device features a rated repetitive off-state voltage of 800 V and an on-state RMS current of 2 A. Key electrical parameters include a non-repetitive peak on-state current of 25 A, a maximum holding current of 50 mA, and a gate trigger current of 10 mA. It operates within a junction temperature range up to +150 °C.

Triacs Feature Summary

• High commutation capability ensures reliable switching in circuits subject to high static and dynamic dv/dt and di/dt conditions.
• Optimized gate sensitivity allows direct interfacing with low-power logic ICs and microcontrollers without additional drive circuitry.
• Planar passivation technology provides enhanced robustness against mechanical stress and environmental factors.

Triacs Applications

• Motor control circuits
• Inductive load switching
• Solid state relays

Triacs Procurement Notes

Verify the specific suffix '116' against the manufacturer's official documentation to confirm packaging details and compliance status. Ensure the component matches the required pinout configuration, as this series utilizes an inverted pin arrangement compared to standard TO-92 triacs. Confirm availability through authorized channels to guarantee authenticity.

Triacs Selection Notes

Select this component when a compact TO-92 package is required for applications demanding high commutation performance and compatibility with low-power digital drivers. The 800 V rating suits general-purpose AC switching, while the 2 A RMS current capacity defines its power handling limits. Consider the inverted pinout during PCB layout design to prevent connection errors.

Triacs Part Context

This part belongs to the BTA201 ER series from WeEn Semiconductors, which focuses on balancing commutation performance with gate sensitivity. The 'ER' designation typically indicates specific characteristics tailored for integration with modern low-power control electronics, distinguishing it from standard high-current industrial triacs.

Triacs Replacement Considerations

Direct substitutes must match the 800 V / 2 A specification, TO-92 package, and three-quadrant operation. Verify that any replacement also features the inverted pinout configuration to ensure physical compatibility without redesigning the footprint.

Triacs FAQ

How does the pinout of the BTA201-800ER differ from standard TO-92 triacs?

The BTA201-800ER features an inverted pin arrangement relative to the standard TO-92 triac pinout. Designers must consult the datasheet diagram to correctly identify Gate, Anode 1, and Anode 2 terminals.

What is the maximum operating junction temperature for this device?

The maximum operating junction temperature (Tj max) for the BTA201-800ER is +150 °C.

Is this triac suitable for driving highly inductive loads?

Yes, the BTA201-800ER is explicitly intended for use in motor control circuits and with other highly inductive loads due to its high commutation capabilities.
