1N4892

Single Zener Diodes Overview

The 1N4892 is a silicon voltage reference diode manufactured by Microsemi Corporation. It features a nominal Zener voltage of 6.35 V and is housed in a DO-7 (DO-204AA) glass axial leaded package. The device is hermetically sealed, ensuring environmental stability. It is designed as an ultra-stable temperature-compensated Zener reference, suitable for precision applications requiring consistent voltage regulation over varying thermal conditions.

• Silicon Zener diode technology for stable regulation

Single Zener Diodes Applications

• Precision voltage reference circuits
• Temperature-compensated regulator designs
• Calibration equipment standards

Single Zener Diodes Procurement Notes

Verify the manufacturer designation, specifically Microsemi or its successors such as Microchip, as corporate acquisitions may affect part sourcing. Confirm the package style matches the required DO-7 form factor. Ensure the component meets specific military or industrial grade requirements if hermetic sealing is critical for the intended environment. Cross-reference datasheets to confirm tolerance specifications before integration.

Single Zener Diodes Selection Notes

Select this component when a stable 6.35 V reference is required with minimal temperature drift. The DO-7 package is suitable for through-hole mounting in standard PCB layouts. Consider the power dissipation limits inherent to the axial leaded glass package when designing the thermal management strategy for the circuit.

Single Zener Diodes Part Context

This component belongs to the family of ultra-stable temperature-compensated Zener reference diodes. These devices are engineered to provide highly accurate voltage references that remain consistent across a wide operating temperature range, distinguishing them from standard Zener diodes used for general clipping or protection.

Single Zener Diodes Replacement Considerations

Check for direct equivalents from Microchip Technology following the acquisition of Microsemi's discrete product line. Verify pinout compatibility and electrical tolerances against other 6.35 V Zener references in the DO-7 package before substitution.
