JANTXV1N5537C-1/TR

Single Zener Diodes Overview

The JANTXV1N5537C-1/TR is a hermetically sealed silicon Zener diode manufactured by Microchip Technology. It features a 17 V nominal Zener voltage with a tight tolerance of 2%. The device operates in the DO-35 glass axial leaded package and supports surface mount or through-hole installation styles depending on the specific variant configuration. It provides a maximum power dissipation of 0.5 W and maintains low reverse leakage characteristics. The component is qualified for extended temperature ranges, functioning reliably from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Hermetically sealed construction utilizing metallurgically bonded double plug design for environmental stability
• Low noise and low reverse leakage characteristics suitable for precision regulation applications
• Extended thermal performance capability supporting operation in extreme high and low temperature environments

Single Zener Diodes Applications

• Military aerospace voltage reference circuits
• Radiation-hardened power supply regulation systems
• High-reliability industrial control protection stages

Single Zener Diodes Procurement Notes

Verify the exact suffix designation against the manufacturer datasheet to confirm package type and tolerance specifications. Ensure procurement channels provide valid traceability documentation required for JAN class components. Confirm that the received units match the specified hermetic sealing standards and do not contain unauthorized modifications or non-compliant packaging materials.

Single Zener Diodes Selection Notes

Select this component when strict hermetic sealing and radiation hardness are mandatory requirements. The 2% voltage tolerance distinguishes it from standard commercial variants. Evaluate the thermal management needs carefully given the 0.5 W power dissipation limit within the small glass package. Consider the extended temperature range benefits for harsh environment deployments where standard diodes would fail prematurely.

Single Zener Diodes Part Context

This part belongs to the MIL-PRF-19500/437 qualified series produced by Microsemi, now part of Microchip Technology. The JAN prefix indicates military-grade quality assurance. The C-1 suffix typically denotes specific voltage binning and tolerance levels within the broader 1N5537 family line. These devices are engineered for critical defense and space applications requiring long-term reliability.

Single Zener Diodes Replacement Considerations

Direct substitutes include JANTX1N5537C-1 for lower qualification tiers and JANTXV1N5537CUR-1 for surface mount equivalents. Verify pin compatibility and hermetic seal integrity before substitution. Standard commercial 1N5537 variants lack the necessary radiation hardness and temperature range.
