Overview
The T405-600B-TR is a four-quadrant sensitive gate triac manufactured by STMicroelectronics, designed for general-purpose AC inductive load control. It features a 600 V repetitive peak off-state voltage and an RMS on-state current rating of 4 A. The device supports non-repetitive surge currents up to 31 A at 50 Hz. Key electrical parameters include a maximum holding current of 10 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 5 mA. It operates within a junction temperature range of -40°C to +125°C and is housed in a surface-mount DPAK (TO-252) package.
Feature Summary
- Logic-level technology enabling direct microcontroller gate drive without additional buffer components
- High commutation performance suitable for demanding AC inductive loads
- Four-quadrant triggering capability for versatile circuit integration
Applications
- Motor driving and control systems
- Electro valves and solenoid actuators
- Kitchen appliances and domestic power tools
- Dishwashers and similar household equipment
Procurement Notes
Verify the specific suffix 'TR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the DPAK thermal pad soldering meets the manufacturer's recommended reflow profile specifications to ensure reliable long-term operation under thermal stress conditions.
Selection Notes
Select this component when a compact surface-mount solution is required for low-power AC switching applications. Ensure the circuit design accommodates the 4 A RMS current limit and verify that the 600 V blocking voltage provides adequate margin for the specific line voltage environment.
Part Context
This part belongs to the T4 series of thyristors from STMicroelectronics, which utilizes Snubberless and logic-level technologies. The series is engineered to provide high commutation performance while minimizing external component requirements for standard AC switching tasks.
Replacement Considerations
The T405Q-600B-TR serves as a verified alternative within the same product family, offering identical electrical ratings and pinout compatibility for direct substitution in existing designs.
