BT138X-600,127

Triacs Overview

The BT138X-600,127 is a glass passivated bidirectional triac manufactured by WeEn Semiconductors. It features an RMS on-state current of 12 A and a non-repetitive peak on-state current of 105 A. The device supports a rated repetitive off-state voltage (VDRM) of 600 V with a maximum leakage current of 100 uA at VDRM. Key electrical parameters include a maximum on-state voltage of 1.4 V, a holding current maximum of 30 mA, a gate trigger voltage of 700 mV, and a gate trigger current of 22 mA. It operates within a temperature range of -40 C to +125 C and is housed in a TO-220FP-3 through-hole package.

Triacs Procurement Notes

Verify the manufacturer part number BT138X-600,127 against official WeEn Semiconductors documentation to confirm specifications. Ensure compliance with RoHS and REACH requirements as specified in the datasheet. Check for any product change notifications that may affect pinout or electrical characteristics before integration into production designs.

Triacs Selection Notes

Select this component when a 12 A RMS current rating and 600 V blocking voltage are required in a TO-220FP-3 package. Consider the 1.4 V on-state voltage for thermal management calculations. Verify that the gate trigger current of 22 mA matches the driving circuit capabilities. Ensure the operating temperature range up to 125 C aligns with the system's thermal environment.

Triacs Part Context
