L401E6RP

Triacs Overview

The Littelfuse L401E6RP is a bidirectional triac from the TECCOR Lx01Ex series, designed for sensitive gate triggering applications. It features a 400 V rated repetitive off-state voltage (VDRM) and conducts an RMS on-state current (It RMS) of 1 A. The device operates within a temperature range of -65 °C to +110 °C and utilizes a TO-92 through-hole package. Key electrical parameters include a maximum holding current of 10 mA, a gate trigger voltage of 2 V, and a gate trigger current of 5 mA. The RP suffix indicates the component is supplied in a tape and reel packaging format.

Triacs Feature Summary

• Sensitive gate architecture requiring low gate trigger current for efficient control
• Bidirectional conduction capability suitable for AC power switching applications
• Robust thermal performance with a wide operating temperature range

Triacs Applications

• Lighting dimmer circuits
• Solid-state relays
• Motor speed control systems

Triacs Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm the tape and reel configuration. Ensure the selected variant matches the required package type and packing option for automated assembly processes. Cross-reference the part number with official Littelfuse catalogs to validate availability and compliance specifications before finalizing procurement orders.

Triacs Selection Notes

Select this component when a low-power triac with sensitive gate characteristics is required for AC load control. The 1 A current rating suits small appliances and lighting loads. Verify that the circuit design accommodates the 5 mA gate trigger requirement and that the TO-92 package fits the available PCB space. Consider the 400 V voltage rating relative to the peak line voltage of the application.

Triacs Part Context

This part belongs to the Littelfuse TECCOR Lx01Ex family of sensitive gate triacs. These devices are engineered for general-purpose AC switching where minimal gate drive power is necessary. The L401E6RP specifically denotes the 400 V, 1 A variant packaged in a tape and reel format for surface mount or automated insertion manufacturing lines.

Triacs Replacement Considerations

Compatible substitutes include other 400 V, 1 A sensitive gate triacs in TO-92 packages such as the BT136 series or equivalent generic alternatives. Verify that replacement parts match the gate trigger current and voltage specifications to ensure proper circuit operation without modification.
