Scrs datasheet and documents for TS820-600B
Scrs Overview
The TS820-600B is a sensitive gate silicon controlled rectifier (SCR) manufactured by STMicroelectronics. It features an 8 A on-state RMS current and a 600 V repetitive peak off-state voltage. The device requires a maximum gate trigger current of 0.2 mA and a maximum gate trigger voltage of 0.8 V. It operates within a junction temperature range of -40°C to 125°C and is housed in a TO-252 (DPAK) surface-mount package.
Scrs Feature Summary
- Sensitive gate triggering capability for low-power control applications
- High thermal stability with operation up to 125°C junction temperature
- Robust surge current handling for transient protection scenarios
Scrs Applications
- Overvoltage crowbar protection circuits
- Motor control in power tools and kitchen appliances
- Inrush current limiting circuits
- Capacitive discharge ignition systems
Scrs Procurement Notes
Verify the specific ordering suffix to confirm the exact packaging configuration, as standard distribution may vary between tubes or reels. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer's latest product change notifications to confirm material consistency and manufacturing origin before finalizing procurement contracts.
Scrs Selection Notes
Select this component when a low gate drive current is required to interface directly with microcontrollers or logic gates. The 600V rating suits single-phase AC mains applications. Consider the TO-252 package for space-constrained PCB layouts requiring surface-mount assembly. Verify that the 8A RMS current meets the continuous load requirements of the specific circuit design.
Scrs Part Context
This SCR belongs to the TS820 series, which provides optimized performance in limited spaces for various control modes. The series includes variants with different voltage ratings and gate sensitivities. The TS820-600B specifically targets applications needing reliable switching at 600V with minimal gate power consumption, fitting into ST's broader portfolio of power control devices for consumer and industrial electronics.
Scrs Replacement Considerations
Direct replacements include other 8A, 600V sensitive gate SCRs from STMicroelectronics such as the TS820-800B for higher voltage tolerance. Cross-brand equivalents must match the 0.2mA gate trigger sensitivity and TO-252 package dimensions to ensure pin compatibility and thermal performance without redesigning the PCB layout.
