Overview
The Microchip Technology JAN1N5819-1 is a military-grade Schottky barrier rectifier designed for high-frequency applications. It features a maximum DC reverse voltage of 45 V and an average forward current rating of 1 A in the DO-41 axial through-hole package. The device exhibits a typical forward voltage drop of 490 mV at 1 A and a reverse leakage current of 50 µA at 45 V. Operating junction temperature ranges from -65°C to 150°C, ensuring reliability in demanding environments.
Feature Summary
- Military-grade qualification compliant with MIL-PRF-19500/586 standards
- Schottky technology enables extremely fast switching with negligible recovery time
- Low forward voltage drop minimizes conduction losses during operation
Applications
- Switch mode power supplies
- High frequency DC to DC converters
- Polarity protection circuits
- Free wheeling diodes in low voltage inverters
Procurement Notes
Verify that the specific JAN1N5819-1 designation confirms military grade compliance rather than commercial variants. Confirm RoHS status as non-compliant due to lead content requirements inherent to the military specification. Ensure the DO-41 axial package matches the intended PCB footprint and mounting constraints for the target assembly.
Selection Notes
Select this component when military reliability and wide operating temperature ranges are required. The 45 V reverse voltage rating provides sufficient margin for 24 V systems. Consider the DO-41 package size for space-constrained through-hole designs requiring robust mechanical leads.
Part Context
This part belongs to the standard 1N5819 series of Schottky rectifiers but carries the JAN prefix indicating it meets strict military performance and screening criteria. It serves as a ruggedized alternative to commercial equivalents, offering enhanced thermal stability and consistent electrical parameters across extreme environmental conditions.
