Overview
The GA201 is a silicon-controlled rectifier (SCR) manufactured by Microchip Technology, designed for robust power switching applications. It features a rated repetitive off-state voltage of 100 V and an RMS on-state current capacity of 200 mA. The device operates within a junction temperature range of -65°C to +150°C and utilizes a TO-18-3 through-hole package. Key electrical characteristics include a forward voltage of 1.1 V, a gate trigger voltage of 600 mV, and a holding current maximum of 5 mA. It supports non-repetitive on-state currents up to 100 A and maintains a low off-state leakage current of 100 nA at the rated voltage.
Feature Summary
- High thermal stability with an extended operating temperature range suitable for demanding environments
- Robust surge handling capability with high non-repetitive on-state current rating
- Low gate sensitivity requiring minimal trigger current for reliable activation
Applications
- Overvoltage protection circuits in power supplies
- Crowbar protection mechanisms for sensitive electronic loads
- Phase control applications in AC power regulation
Procurement Notes
Verify the specific suffix and packaging configuration against the manufacturer's latest datasheet before ordering. Confirm that the TO-18-3 lead frame compatibility matches your assembly requirements. Ensure that the procurement channel provides traceability documentation consistent with Microchip Technology standards for quality assurance purposes.
Selection Notes
Select this component when a compact hermetic or semi-hermetic SCR is required for low-current switching tasks. Evaluate the 100 V voltage rating against peak circuit transients to ensure adequate safety margins. Consider the 200 mA RMS current limit for continuous load conditions and verify that the gate trigger specifications align with the driving circuit capabilities.
Part Context
The GA201 belongs to Microchip Technology's discrete thyristor portfolio, specifically engineered for reliable semiconductor switching. It complements other SCRs like the GA301 series but offers distinct thermal and electrical parameters tailored for specific industrial and commercial applications requiring compact form factors.
Replacement Considerations
Consult official Microchip substitution guides for direct equivalents. Verify pinout compatibility and thermal resistance values when considering alternative manufacturers. Ensure that any substitute device meets the same voltage and current ratings without compromising circuit safety.
