JANTX1N4100CUR-1

Single Zener Diodes Overview

The JANTX1N4100CUR-1 is a single Zener diode manufactured by Microchip Technology, designed for surface-mount applications in the DO-213AA package. It provides a nominal Zener voltage of 7.5 V with a tight tolerance of ±2%. The device features a maximum power dissipation of 500 mW and operates within an extended temperature range of -65°C to 175°C. Key electrical characteristics include a maximum reverse leakage current of 1 µA at 5.7 V and a maximum Zener impedance of 200 Ohms. The forward voltage is specified as 1.1 V at 200 mA. This component meets the MIL-PRF-19500/435 qualification standard.

Single Zener Diodes Procurement Notes

Verify that the specific part number includes the CUR-1 suffix to confirm the surface-mount DO-213AA configuration and reel packaging. Ensure compliance with MIL-PRF-19500/435 requirements is documented for procurement. Confirm the manufacturer source is authorized to guarantee authenticity and traceability for qualified components.

Single Zener Diodes Selection Notes

Select this component when a precise 7.5 V reference is required in a surface-mount form factor. The ±2% tolerance offers higher precision than standard commercial variants. Consider the DO-213AA footprint constraints and the need for high-temperature operation up to 175°C during design integration.

Single Zener Diodes Part Context

This part belongs to the JANTX series of Zener diodes from Microchip, which are derived from the 1N4100 family but optimized for ruggedized applications. The 'JANTX' designation indicates a specific quality level within the military qualification spectrum, distinct from standard commercial or basic military grades.

Single Zener Diodes Replacement Considerations

Direct substitutes include other JANTX1N4100 variants from different manufacturers if they meet the same MIL-PRF-19500/435 specification. Verify pinout compatibility and thermal performance before substitution.
