Q201E3

Triacs Overview

The Q201E3 is a logic-sensitive gate TRIAC manufactured by Littelfuse Inc., designed for AC switching and phase control applications. It features a bidirectional solid-state switch configuration with a rated repetitive off-state voltage of 200 V and an on-state current rating of 1 A. The device is housed in a TO-92 through-hole package. Key electrical specifications include an off-state leakage current of 20 uA at VDRM, an on-state voltage of 1.6 V, and a maximum holding current of 15 mA. This component is part of the Teccor Electronics gated TRIAC line, intended for motor speed and temperature modulation tasks.

Triacs Feature Summary

• Logic-sensitive gate design for efficient triggering
• Bidirectional AC switching capability
• Through-hole TO-92 packaging

Triacs Applications

• Motor speed control
• Temperature modulation systems
• AC phase control circuits

Triacs Procurement Notes

Verify availability status as the Q201E3 is listed as obsolete and no longer manufactured by Littelfuse Inc. Check official distributor channels for remaining stock or confirm end-of-life notifications. Ensure compliance with RoHS3 standards if required for specific projects. Consult manufacturer documentation for final disposition details regarding this discontinued part number before initiating procurement processes.

Triacs Selection Notes

Consider the Q401E3 as a potential upgrade substitute within the same product family. Evaluate whether the 200 V voltage rating and 1 A current capacity meet the specific circuit requirements. Assess the logic-sensitive gate trigger characteristics against available drive signals. Review thermal management needs for the TO-92 package in the target application environment.

Triacs Part Context

The Q201E3 belongs to the broad line of bidirectional semiconductors from Teccor Electronics, now under Littelfuse. This series includes devices ranging from 0.8 A to 35 A current ratings. The Q201E3 specifically addresses low-power AC switching needs with its 1 A rating. It represents a legacy component in the company's TRIAC portfolio, previously widely used in consumer electronics and industrial control modules.

Triacs Replacement Considerations

The Q401E3 is identified as an available substitute part number. Verify pinout compatibility and electrical parameter alignment between the Q201E3 and Q401E3 before implementation. Confirm that the replacement meets all original design specifications for voltage, current, and package type.
