BT138-600-0TQ

Triacs Overview

The BT138-600-0TQ is a four-quadrant TRIAC manufactured by WeEn Semiconductors, designed for AC power control applications. It features a peak repetitive off-state voltage of 600 V and an RMS on-state current rating of 12 A. The device supports non-repetitive surge currents up to 95 A and maintains a maximum holding current of 30 mA. Gate triggering requirements include a voltage of 700 mV and a current of 22 mA. Operating within a temperature range of -40 °C to +125 °C, it utilizes a TO-220AB-3 through-hole package with a typical on-state voltage of 1.4 V.

Triacs Feature Summary

• Four-quadrant gate sensitivity ensures reliable triggering across all combinations of main terminal polarity and gate signal phase.
• Planar passivated construction provides robust protection against mechanical stress and environmental factors.
• High thermal stability allows sustained operation at elevated junction temperatures up to 125 °C.

Triacs Applications

• Industrial motor speed control systems
• Solid-state relays for high-power switching
• Lighting dimmers for commercial fixtures

Triacs Procurement Notes

Verify the specific suffix '0TQ' to confirm the tape-and-reel packaging configuration intended for automated assembly processes. Ensure that the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity and traceability. Confirm compliance with RoHS directives and check for any recent Product Change Notifications (PCN) regarding manufacturing site transfers or material updates before finalizing orders.

Triacs Selection Notes

Select this component when a 600 V blocking capability and 12 A continuous current handling are required in a standard through-hole footprint. The TO-220AB-3 package offers effective heat dissipation for moderate power levels without requiring complex thermal management solutions. Consider the 22 mA gate trigger current when designing drive circuits to ensure sufficient power delivery from the control logic under varying temperature conditions.

Triacs Part Context

This part belongs to the BT138 series of four-quadrant TRIACs, which are widely used in general-purpose AC switching applications. The series is characterized by its planar passivation technology, offering improved reliability compared to older generation devices. The BT138-600 variant specifically targets applications requiring medium voltage isolation and moderate current capacity in industrial and consumer electronics.

Triacs Replacement Considerations

Cross-reference with BT138-600E,127 for equivalent electrical performance in a similar TO-220AB-3 package. Verify pinout compatibility and thermal resistance characteristics when substituting to ensure circuit integrity and proper mounting constraints are maintained.
