Overview
The Microchip Technology 1N6332 is a 22 V Zener diode with a maximum power dissipation of 500 mW. It features a nominal voltage tolerance of ±5% and a dynamic impedance of 20 Ohms at the test current of 5.6 mA. The device operates within a junction temperature range of -65 °C to +175 °C and utilizes a DO-204AH (DO-35) axial leaded package.
Feature Summary
- Hermetically sealed voidless glass construction with internal metallurgical bonds for high reliability
- Military qualification per MIL-PRF-19500/533 across JAN, JANTX, JANTXV, and JANS levels
- Inherently radiation hard design suitable for demanding environments
Applications
- High-reliability voltage regulation circuits
- Radiation-hardened electronic systems
- Military-grade power management modules
Procurement Notes
Verify the specific reliability level suffix (JAN, JANTX, JANTXV, or JANS) required for your application, as these denote different qualification standards under MIL-PRF-19500/533. Confirm RoHS compliance status if applicable, noting that commercial versions may differ from military qualified parts. Ensure the package type matches the DO-35 axial lead specification.
Selection Notes
Select this component when a robust, hermetically sealed Zener regulator is needed for critical applications. The 22 V breakdown voltage and 500 mW rating suit moderate current regulation tasks. Consider tighter tolerance variants (1% or 2%) if standard 5% accuracy is insufficient for the circuit requirements.
Part Context
This part belongs to the 1N6309 through 1N6355D series of 500 mW glass Zener diodes. The series offers a wide voltage selection from 2.4 V to 200 V. These devices are industry-recognized for their voidless-glass construction and internal metallurgical bonding, providing superior durability compared to standard commercial equivalents.
Replacement Considerations
Equivalent parts include JAN1N6332C, JAN1N6332D, JANS1N6332C, and JANTX1N6332C. Verify that substitute components meet the same MIL-PRF-19500/533 qualification levels and package specifications.
