Overview
The GA301A is a Silicon Controlled Rectifier (SCR) manufactured by Microchip Technology, designed for through-hole mounting in the TO-18-3 package. It features a rated repetitive off-state voltage of 100 V and a maximum holding current of 5 mA. The device operates within a temperature range of 0°C to +125°C. Key electrical characteristics include a gate trigger voltage of 500 mV, a gate trigger current of 10 µA, and a maximum gate peak reverse voltage of 5 V. The component exhibits a low off-state leakage current of 1 µA at the rated voltage.
Feature Summary
- High surge current capability with a non-repetitive on-state current rating of 100 A
- Low gate sensitivity requiring minimal trigger current for reliable activation
- Robust thermal performance suitable for high-temperature industrial environments
Applications
- Phase control circuits for AC power regulation
- Solid-state relay implementations
- Overvoltage protection systems utilizing crowbar configurations
Procurement Notes
Verify the specific suffix designation against official Microchip documentation to ensure correct pinout and electrical ratings. Confirm RoHS compliance status via the manufacturer's datasheet before integration. Validate that the TO-18-3 package dimensions align with the target PCB footprint requirements.
Selection Notes
Select this component when a hermetically sealed glass-passivated SCR is required for high-reliability applications. Ensure the circuit design accommodates the 100 V blocking voltage and the 5 mA holding current threshold. Consider the 100 A surge capacity for transient load conditions during normal operation.
Part Context
This device belongs to the Microchip thyristor product line, specifically categorized under SCRs. It serves as a discrete switching element within the broader portfolio of power control components offered by the manufacturer for industrial and commercial electronic systems.
Replacement Considerations
Consult the official Microchip replacement guide for direct equivalents. Verify compatibility regarding package style, voltage ratings, and trigger characteristics before substituting with other manufacturers' TO-18-3 SCRs.
