JANTX1N962C-1/TR

Single Zener Diodes Overview

The JANTX1N962C-1/TR is a hermetically sealed silicon Zener diode manufactured by Microchip Technology. It features an 11 V nominal Zener voltage with a tight ±2% tolerance, designated by the 'C' suffix. The device operates in a DO-35 axial glass package and dissipates up to 500 mW of power. Key electrical parameters include a maximum reverse leakage current of 1 µA, a Zener impedance of 9.5 Ω at a test current of 11.5 mA, and a forward voltage of 1.1 V at 200 mA. It supports a wide operating temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Hermetically sealed construction in a glass DO-35 axial leaded package for environmental protection
• High precision voltage regulation with ±2% tolerance for critical reference applications
• Extended thermal stability enabling operation in extreme temperatures from -65°C to +175°C

Single Zener Diodes Applications

• Military aerospace voltage regulation circuits
• Precision reference voltage sources in harsh environments
• Overvoltage protection in defense electronics

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against the purchase order, as variations such as JAN, JANTX, or JANTXV denote different quality levels and testing standards per MIL-PRF-19500/117. Confirm that the reel packaging matches the automated assembly requirements. Ensure the component meets the required radiation hardness or reliability specifications if intended for space-grade missions.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is required under extreme thermal conditions. The ±2% tolerance makes it suitable for high-accuracy analog circuits where standard commercial diodes would introduce unacceptable error. The hermetic seal is essential for applications exposed to moisture, vibration, or vacuum environments typical in military and aerospace systems.

Single Zener Diodes Part Context

This part belongs to the 1N957B through 1N986B series of silicon Zener diodes produced under the MIL-PRF-19500/117 specification. The JANTX designation indicates enhanced screening compared to standard JAN parts, ensuring higher reliability for military applications. The series covers a wide range of voltages, with the 1N962 variant specifically providing an 11 V reference point.

Single Zener Diodes Replacement Considerations

Direct equivalents include JANTX1N962B-1 for 5% tolerance or JANTXV1N962C for higher reliability grades. Cross-brand replacements must match the 11 V Zener voltage, 500 mW power rating, DO-35 package, and hermetic sealing requirements.
