BTA04-600SRG

Triacs Overview

The BTA04-600SRG is a sensitive gate triac manufactured by STMicroelectronics, designed for general-purpose phase control and static switching applications. It features a glass passivated PNPN structure housed in a TO-220AB through-hole package with three pins. The device supports an RMS on-state current of 4 A and withstands repetitive peak off-state voltages up to 600 V. Key electrical parameters include a maximum gate trigger current (Igt) of 10 mA, a maximum holding current (Ih) of 15 mA, and a peak on-state voltage of 1.65 V. It operates within a junction temperature range of -40°C to +110°C.

Triacs Feature Summary

• Sensitive gate design enabling reliable triggering with low gate drive currents.
• Glass passivation provides enhanced protection against moisture and chemical contamination.
• High insulation voltage rating suitable for demanding industrial environments.

Triacs Applications

• Phase control circuits for AC power regulation.
• Static switching applications requiring high sensitivity.
• General purpose AC motor speed control systems.

Triacs Procurement Notes

Verify the specific suffix 'SRG' against official STMicroelectronics documentation to confirm RoHS compliance and packaging details. Ensure the component matches the TO-220AB form factor and that the manufacturer identification aligns with STMicroelectronics rather than third-party distributors hosting the datasheet.

Triacs Selection Notes

Select this component when a 4 A RMS current rating and 600 V blocking voltage are required. The sensitive gate characteristic makes it suitable for applications where minimal gate drive power is available. Confirm that the TO-220AB package fits the thermal and mechanical constraints of the target PCB or heatsink assembly.

Triacs Part Context

This part belongs to the BTA/BTB04 triac family from STMicroelectronics. These devices are characterized by high performance and reliability in sensitive gate applications. The family is widely used in consumer and industrial electronics for controlling AC loads where compact size and robust operation are necessary.

Triacs Replacement Considerations

Compatible substitutes include the BTA04-600T and BTA04-600TRG. Verify that alternative parts maintain the same 4 A current rating, 600 V voltage rating, and TO-220 package to ensure direct compatibility without circuit redesign.
