JAN1N968CUR-1

Single Zener Diodes Overview

The JAN1N968CUR-1 is a silicon Zener voltage regulator diode manufactured by Microchip Technology. It operates within the 1N957BUR-1 to 1N992BUR-1 series and provides a nominal Zener voltage of 20 V with a ±2% tolerance. The device features a maximum Zener impedance of 25 Ohms and a test current of 6.2 mA. It is housed in a hermetically sealed DO-213AA (MELF) surface-mount package. The component supports a steady-state power dissipation of 0.5 W at an end cap temperature of +125°C, with an operating and storage temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass MELF package with internal metallurgical bond
• Qualified per MIL-PRF-19500/117 for JAN reliability levels
• Inherently radiation hard design
• Non-sensitive to electrostatic discharge

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• High density surface mount mounting applications
• Radiation-hardened electronic systems

Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required military qualification level and tolerance suffix. Confirm RoHS compliance status if applicable, as commercial versions differ from military qualified units. Ensure the ordering suffix aligns with the desired packaging format, such as bulk or tape and reel options available through the manufacturer.

Single Zener Diodes Selection Notes

Select this component when a precise 20 V reference is required in a compact surface-mount form factor. The DO-213AA package facilitates automated placement while maintaining high thermal performance. Consider the low leakage current and tight voltage tolerance for sensitive analog circuits requiring stable regulation under varying thermal conditions.

Single Zener Diodes Part Context

This device belongs to the 1N957BUR-1 through 1N992BUR-1 series of 0.5 watt Zener diodes. The series offers a wide selection of voltages from 6.8 to 200 volts. Military qualified versions are specifically available for the 1N962BUR-1 through 1N992BUR-1 range, ensuring suitability for demanding environments requiring strict reliability standards.

Single Zener Diodes Replacement Considerations

Compatible substitutes include JANTX1N968BUR-1 and JANTXV1N968BUR-1, which share the same electrical characteristics but offer different military reliability levels. Commercial equivalents like 1N968CUR-1 may be used if military qualification is not required.
