JANTX1N3019C-1/TR

Single Zener Diodes Overview

The JANTX1N3019C-1/TR is a silicon unidirectional voltage regulator diode manufactured by Microchip Technology. It operates within a temperature range of -65°C to +175°C and features a maximum power dissipation of 1 W. The device provides a nominal reference voltage of 9.1 V with a knee impedance of up to 700 Ω. It utilizes a DO-13 metal package with a round, long-form shape and cathode-connected case. This component is designed for high-reliability applications requiring stable voltage regulation under extreme thermal conditions.

Single Zener Diodes Procurement Notes

Verify the specific suffix C-1 against official Microchip documentation to confirm exact tolerance and testing parameters. Ensure the reel packaging matches system requirements. Confirm RoHS status as non-compliant for this qualified level. Validate that the DO-13 package dimensions fit the designated footprint on the printed circuit board assembly before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 9.1 V zener voltage is required in a through-hole metal package. Consider the 1 W power rating for thermal management capabilities. Evaluate the 700 Ω knee impedance for low-current regulation needs. Compare against other series members like the 1N3016B-1 or 1N3025C-1 if different voltage levels are needed while maintaining the same qualification standard.

Single Zener Diodes Part Context

This part belongs to the established 1N3016B-1 through 1N3045B-1 series of 1 Watt Zener diodes. These devices are JEDEC registered and available in various military qualifications. The series offers a wide voltage range from 6.8 V to 110 V in a glass DO-41 package, though this specific variant uses a DO-13 metal case. The series is well-suited for applications demanding high reliability and hermetic sealing.

Single Zener Diodes Replacement Considerations

Direct substitutes include other JANTX qualified zener diodes with identical 9.1 V ratings and 1 W power dissipation. Verify package compatibility between DO-13 and DO-41 forms if physical space allows. Check manufacturer datasheets for equivalent parts from Microsemi or NXP families sharing the same MIL-PRF-19500/115 qualification.
