T1M5F600AL

Overview

The T1M5F600AL is a silicon bidirectional thyristor (Triac) manufactured by Lite-On Semiconductor Corporation, distributed by Diodes Incorporated. It features a one-piece injection-molded package in the TO-92 (TO-226AA) configuration. The device supports a peak repetitive off-state voltage of 600 Volts and an on-state RMS current of 1.0 Ampere at a case temperature of 50°C. It offers high surge current capability of 12.0 Amps for non-repetitive full-cycle sine waves at 60 Hz. The component operates within a junction temperature range of -40 to +110°C and includes sensitive gate triggering across four quadrants.

Feature Summary

• Sensitive gate triggering designed for all possible combinations of trigger sources, particularly circuits that source gate drives.
• All diffused and glassivated junctions ensure maximum uniformity of parameters and reliability.
• Injection-molded package construction provides improved noise immunity with a minimum dv/dt rating.

Applications

• Lighting control systems requiring low-power triac switching
• Solid-state relay applications utilizing sensitive gate inputs
• General-purpose AC power control circuits

Procurement Notes

Verify the manufacturer designation as Lite-On Semiconductor Corporation when sourcing this part, despite the distributor listing. Confirm the specific ordering suffix 'AL' corresponds to the Pb-free package variant documented in the datasheet revision dated July 2013. Ensure the TO-92 pinout matches Main Terminal 1, Main Terminal 2, and Gate assignments for your PCB layout requirements.

Selection Notes

Select this component for applications requiring a 600V blocking voltage and 1A RMS current handling in a compact through-hole package. Consider the sensitive gate characteristics if the driving circuit has limited current output capability. Evaluate the thermal resistance values against the expected ambient temperature conditions to ensure the junction temperature remains within the specified operating range during continuous operation.

Part Context

This Triac belongs to the family of silicon bidirectional thyristors designed for general AC switching. It utilizes a TO-92 package suitable for low-power density designs. The device distinguishes itself through sensitive gate triggering modes and robust junction technology aimed at maintaining parameter uniformity across production batches.

Replacement Considerations

Direct substitutes must match the 600V VDRM/VRRM rating, 1.0A IT(RMS) current capacity, and TO-92 package outline. Verify that replacement parts also support sensitive gate triggering if the original design relies on low gate drive currents. Check thermal resistance specifications to ensure equivalent heat dissipation performance.
