Additional Details

The BT137S-800G is housed in a surface mount SOT428 (DPAK) package. The '800' in the part number refers to the 800V blocking voltage, which is the maximum voltage the triac can withstand in the off state. The 'G' indicates that it is a sensitive gate triac. The '118' is a packing code.

Key Specifications:

• Repetitive peak off-state voltage: 800 V
• On-state RMS current: 8 A
• Gate trigger current: 5 mA
