Overview
The GA301E3 is a Silicon Controlled Rectifier (SCR) manufactured by Microchip Technology. It features a TO-18-3 through-hole package and operates within a temperature range of 0°C to +125°C. Key electrical specifications include a rated repetitive off-state voltage (VDRM) of 100 V, a maximum holding current (Ih) of 5 mA, and a gate trigger voltage (Vgt) of 500 mV. The device exhibits a maximum gate peak reverse voltage of 5 V and a gate trigger current (Igt) of 10 uA. Leakage current at VDRM is limited to 1 uA, while the non-repetitive on-state current capability reaches 100 A.
Feature Summary
- High surge current handling with 100 A non-repetitive on-state current rating
- Low gate sensitivity requiring only 10 uA trigger current for activation
- Robust thermal performance supporting operation up to +125°C junction temperature
Applications
- Industrial control circuits requiring reliable switching
- Power regulation systems utilizing thyristor-based topologies
- Protection circuits leveraging high surge current capacity
Procurement Notes
Verify the specific suffix 'E3' against the manufacturer's official datasheet to confirm lead-free compliance and packaging details. Ensure the TO-18-3 through-hole form factor matches the target PCB footprint. Confirm that the 100 V voltage rating and 100 A surge capability align with the circuit's operational requirements before finalizing procurement.
Selection Notes
Select this component when a low-cost, high-surge SCR is required for moderate voltage applications up to 100 V. The TO-18-3 package suits prototyping or applications where through-hole mounting is preferred. Verify that the 500 mV gate trigger voltage is compatible with the driving logic levels in the design.
Part Context
The GA301E3 belongs to Microchip's discrete thyristor portfolio, specifically designed for general-purpose switching applications. As part of the GA series, it offers a balance of high surge capability and low gate drive requirements. The E3 suffix typically denotes environmental compliance, distinguishing it from standard commercial variants.
Replacement Considerations
Consult Microchip's official cross-reference documentation for direct replacements. Generic SCRs with identical 100 V VDRM, TO-18-3 packaging, and similar Igt/Ih ratings may serve as functional substitutes if pinout compatibility is verified.
