JAN1N963CUR-1

Single Zener Diodes Overview

The JAN1N963CUR-1 is a silicon Zener diode in a DO-213AA MELF package, qualified to MIL-PRF-19500/117. It features a nominal voltage of 12V with a ±2% tolerance and a test current of 10.5mA. The device has a maximum impedance of 11.5 Ohms and operates from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass MELF construction with internal metallurgical bond
• Qualified to MIL-PRF-19500/117 for JAN level reliability
• Inherently radiation hard design

Single Zener Diodes Applications

• Voltage regulation over broad operating ranges
• High density surface mount mounting
• Radiation-hardened circuit protection

Single Zener Diodes Procurement Notes

Verify the specific suffix 'C' indicates the required ±2% voltage tolerance. Confirm RoHS status as commercial versions differ from military specifications. Ensure the ordering part number matches the exact JEDEC series requirements for your application.

Single Zener Diodes Selection Notes

Select this component when a 12V reference with tight tolerance is needed in a small surface-mount footprint. Consider the thermal resistance values for power dissipation limits at elevated temperatures. Verify compatibility with the target PCB material expansion coefficients.

Single Zener Diodes Part Context

This part belongs to the 1N957BUR-1 through 1N992BUR-1 series of 0.5W Zener regulators. The JAN prefix denotes military qualification levels including JAN, JANTX, and JANTXV. The CUR-1 suffix specifies the surface mount MELF package configuration.

Single Zener Diodes Replacement Considerations

Compatible substitutes include JAN1N962CUR-1 and JAN1N964CUR-1 within the same series. Verify that replacement parts maintain the required voltage tolerance and package dimensions for direct board integration.
