Scrs datasheet and documents for 2N2329A
Scrs Overview
The 2N2329A is a silicon-controlled rectifier (SCR) manufactured by Microchip Technology, designed for military applications under the MIL-PRF-19500/276 qualification standard. It features a sensitive gate structure housed in a TO-5 metal can package with through-hole mounting. The device supports an operating temperature range from -65°C to +125°C and provides a maximum repetitive peak off-state voltage of 200 V. Key electrical characteristics include a maximum average on-state current of 220 mA, a maximum gate trigger voltage of 600 mV, and a maximum gate trigger current of 20 µA.
Scrs Feature Summary
- Qualified for military specifications under MIL-PRF-19500/276 standards
- Sensitive gate architecture enabling low-power triggering
- Robust TO-5 metal can construction for harsh environments
Scrs Applications
- Military-grade power control systems
- High-reliability switching circuits
- Harsh environment electronic protection
Scrs Procurement Notes
Verify procurement channels carefully as this component is part of a specialized military series. Confirm that the specific lot meets the required MIL-PRF-19500/276 qualification standards. Check for any recent manufacturing changes or obsolescence notices from Microchip Technology before finalizing acquisition plans.
Scrs Selection Notes
Select the 2N2329A when military reliability and radiation hardness are required. Ensure the circuit design accommodates the 200 V blocking capability and 220 mA load current. Verify that the sensitive gate requirements align with the available drive signal strength and noise immunity needs of the application.
Scrs Part Context
This SCR belongs to the 2N2323–2N2329A family of devices produced by Microchip Technology. These components share similar structural characteristics but differ in voltage ratings and specific military qualifications within the MIL-PRF-19500/276 specification line.
Scrs Replacement Considerations
Direct replacements must meet the same MIL-PRF-19500/276 military qualification. Consider other parts within the 2N2323–2N2329A series if voltage or current ratings differ slightly. Verify pinout compatibility with the TO-5 package before substitution.
