WeEn Semiconductors Co., Ltd TRIAC Surface Mount TO-252 Package 600 V 8A BT137S-600,118

WeEn Semiconductors Co., Ltd BT137S-600,118 is a surface mount TRIAC semiconductor device designed with a TO-252 (SOT428/DPAK) package. This device supports a repetitive peak reverse voltage of 600 Volts and an average on-state current (Irms) of 8 Amperes, making it suitable for power management and control applications in industrial and consumer electronics.

The TRIAC features planar passivated technology providing ruggedness and high reliability across a wide temperature range from -40°C to 125°C. Its gate requires a minimal trigger voltage of 1.5 Volts and trigger current of 70 mA, with a holding current of 20 mA, enabling efficient and noise-immune operation. The device supports bidirectional control and phase angle triggering in all four quadrants.

This model’s compact TO-252 surface package eases PCB mounting for automated assembly in power switching, light dimming, motor control, and heater control circuits typically found in industrial, commercial, and residential devices.

The peak on-state voltage drop reaches 1.65 Volts, with a surge current capability rated at 71 Amperes to tolerate temporary overloads. Repetitive peak off-state current is 0.5 mA, reducing leakage during blocking states.

The device is RoHS compliant, ensuring environmentally friendly manufacturing practices. Made in China, it represents a reliable component choice for discrete semiconductor applications requiring stable performance and longevity.

Rated average on-state current of 8 Amperes allows robust power switching. Repetitive peak reverse voltage of 600 Volts enables use in moderate voltage AC and DC circuits. Low gate trigger requirements minimize control power consumption.
