Overview
The Microchip Technology 1N3012A is a high-reliability Zener diode designed for demanding environments. It features a nominal Zener voltage of 140 V with a 5% tolerance and operates within an extended temperature range from -65°C to +175°C. The device utilizes a Stud Mount installation style in a DO-213AA-2 package, supporting a power dissipation of 10 W. Key electrical characteristics include a maximum reverse leakage current of 10 uA at test conditions, a Zener impedance of 125 Ohms, and a forward voltage of 1.5 V. Qualified per MIL-PRF-19500/308 standards, it ensures robust performance in critical applications.
Feature Summary
- Qualified per MIL-PRF-19500/308 for high reliability
- Extended operating temperature range up to +175°C
- Stud Mount configuration for efficient thermal management
Applications
- Military aerospace systems
- High-reliability industrial power supplies
- Harsh environment protection circuits
Procurement Notes
Verify the specific revision level and lot traceability documentation upon order confirmation. Ensure that the procurement channel provides valid military qualification certificates consistent with MIL-PRF-19500/308 requirements. Confirm mechanical mounting dimensions match the DO-213AA-2 specification before integration into the final assembly design.
Selection Notes
Select this component when high voltage regulation stability is required under extreme thermal conditions. The stud mount package facilitates direct heat sinking to chassis or cold plates. Verify that the system's peak reverse voltage does not exceed the rated breakdown voltage to maintain safe operation margins during transient events.
Part Context
This part belongs to Microchip's family of high-reliability semiconductor devices intended for defense and space applications. It shares the same qualification standard as other components in the MIL-PRF-19500/308 series, ensuring compatibility with established ruggedized electronic designs requiring long-term operational stability.
Replacement Considerations
Direct substitutes must meet identical MIL-PRF-19500/308 qualifications. Verify pinout compatibility and thermal resistance values. Cross-reference with other manufacturers offering equivalent stud-mount Zener diodes only if they provide full military compliance documentation.
