Overview
The Microchip Technology 2N2326 is a silicon-controlled rectifier (SCR) designed for military applications, qualified under MIL-PRF-19500/276. It features a sensitive gate structure housed in a TO-5 metal can package with through-hole mounting. The device supports a maximum repetitive off-state voltage of 200 V and an average on-state current of 220 mA. Gate triggering requirements are specified with a maximum gate trigger voltage of 600 mV and a maximum gate trigger current of 20 µA. The holding current is rated at a maximum of 2 mA. The component operates within a temperature range of -65°C to 125°C.
Feature Summary
- Military-grade qualification compliant with MIL-PRF-19500/276 standards
- Sensitive gate architecture enabling low-power control signals
- Robust TO-5 metal can construction for harsh environment reliability
Applications
- Military electronic systems requiring high-reliability switching
- Cryogenic circuit operation due to extended low-temperature rating
- High-temperature industrial control environments
Procurement Notes
Verify the specific suffix designation when ordering, as variants such as JAN2N2326A exist with identical electrical characteristics but distinct qualification levels. Confirm that the procurement source provides components manufactured by Microchip Technology or its authorized licensee. Ensure the delivery matches the required military specification grade rather than commercial equivalents. Check for recent product change notices regarding manufacturing origin updates.
Selection Notes
Select this component when a ruggedized SCR with low gate drive power is required for critical systems. The TO-5 package necessitates through-hole PCB layout considerations. Evaluate thermal management capabilities against the 220 mA on-state current limit. Ensure the application voltage does not exceed the 200 V off-state rating. Consider the -65°C lower temperature limit for space or arctic deployments.
Part Context
The 2N2326 belongs to the 2N2323–2N2329A series of silicon controlled rectifiers produced by Microchip Technology. This family is characterized by military-grade screening and radiation hardness suitable for defense aerospace applications. The devices share similar pinouts and mechanical dimensions while offering variations in voltage and current ratings.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other manufacturers requires independent verification of MIL-PRF-19500/276 compliance and exact parameter matching.
