BT137B-800G,118

Triacs Overview

The BT137B-800G,118 is a four-quadrant logic level triac manufactured by WeEn Semiconductors. It features an RMS on-state current rating of 8 A and a repetitive peak off-state voltage (VDRM) of 800 V. The device supports a non-repetitive peak on-state current of 71 A with a maximum on-state voltage of 1.3 V. Gate triggering requirements include a maximum gate trigger voltage (VGT) of 700 mV and a maximum gate trigger current (IGT) of 30 mA. The component operates within a temperature range of -40°C to +125°C and utilizes a D2PAK-3 surface-mount package.

Triacs Feature Summary

• Four-quadrant sensitivity enables reliable triggering across all gate polarities and main terminal voltages.
• Logic-level gate drive characteristics allow direct interfacing with standard digital logic circuits.
• High thermal stability supports continuous operation at junction temperatures up to 125°C.

Triacs Applications

• Lighting control systems requiring high-voltage AC switching
• Solid-state relays for industrial load management
• Motor speed control applications in household appliances

Triacs Procurement Notes

Verify the complete part number including the suffix to ensure correct packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for specific REACH SVHC declarations if required by regional regulations. Ensure storage conditions align with moisture sensitivity level specifications to prevent package damage during assembly.

Triacs Selection Notes

Select this component when an 8 A RMS current capacity and 800 V blocking voltage are required in a surface-mount format. The low gate trigger current facilitates interface with microcontrollers or logic gates without additional driver circuitry. Consider the D2PAK-3 package dimensions for PCB layout constraints and thermal dissipation requirements relative to the expected load current.

Triacs Part Context

This triac belongs to the BT137 series of four-quadrant devices designed for general-purpose AC power control. The series offers various voltage ratings and package options to suit different application needs. The BT137B variant specifically denotes the 800 V rating, while the G suffix typically indicates lead-free composition compliant with environmental directives.

Triacs Replacement Considerations

Compatible substitutes include the BT137B-600 for lower voltage applications or the BT137S-800 for alternative surface-mount packaging. Verify that any replacement maintains the 8 A RMS current rating and compatible gate trigger parameters to ensure circuit functionality remains unchanged.
