Overview
The Microchip Technology 1N3041B-1 is a unidirectional voltage regulator diode constructed from silicon. It features a nominal Zener voltage of 74.5 V and a DC power dissipation rating of 1 watt at a lead temperature of +95°C. The device utilizes a DO-13 axial leaded package with metallurgical bonding. It supports an operating and storage temperature range from -65°C to +175°C, complying with MIL-PRF-19500/115 standards for JAN, JANTX, and JANTXV grades.
Feature Summary
- Metallurgically bonded construction for enhanced thermal stability
- Compliance with MIL-PRF-19500/115 military specifications
- Wide operating temperature range suitable for extreme environments
Applications
- Military aerospace electronic systems
- High-reliability voltage regulation circuits
- Extreme temperature industrial control applications
Procurement Notes
Verify the specific quality grade (JAN, JANTX, or JANTXV) required for your application, as these designations indicate different reliability levels under MIL-PRF-19500/115. Confirm that the DO-13 package dimensions match your board layout constraints. Ensure the supplier provides traceability documentation consistent with military procurement standards.
Selection Notes
Select this component when a precise 74.5 V reference is needed in high-temperature environments. The 1W power rating allows for significant current handling compared to lower-power variants. Consider the axial lead form factor for through-hole mounting requirements where surface mount options are unsuitable for mechanical stress reasons.
Part Context
This part belongs to the 1N3016B-1 through 1N3045B-1 series of 1-watt Zener diodes manufactured by CDI-DIODE and distributed by Microchip Technology. The series covers a wide voltage range, with the 1N3041B-1 positioned near the higher end at 74.5 V. These components are designed for ruggedized applications requiring strict adherence to military performance standards.
Replacement Considerations
Direct substitutes must match the 74.5 V Zener voltage, 1W power rating, and DO-13 package. Verify compatibility with MIL-PRF-19500/115 if military qualification is mandatory. Generic commercial equivalents may lack the required temperature range or reliability metrics.
