1N5534

Overview

The Microchip Technology 1N5534 is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 14 V with a tolerance of 5%. The device operates within a power dissipation rating of 500 mW and maintains a maximum reverse leakage current of 10 nA at the specified test current of 1 mA. It utilizes a DO-35-2 axial through-hole package, supporting an operating temperature range from -65 °C to +175 °C.

Feature Summary

• Provides stable voltage regulation using avalanche breakdown characteristics in a compact glass-encapsulated form factor.

Applications

• Voltage reference circuits
• Overvoltage protection stages
• Biasing networks

Procurement Notes

Verify the specific suffix (e.g., B, D, A) against project requirements as these denote distinct voltage tolerances or testing criteria. Confirm package availability and environmental compliance status directly with the manufacturer or authorized distributors prior to ordering.

Selection Notes

Select this component when a precise 14 V reference is required with low leakage characteristics. Ensure the thermal environment supports the specified wide operating temperature range and that the 500 mW power dissipation limit accommodates the circuit's steady-state conditions.

Part Context

This part belongs to the standard 1N55xx series of Zener diodes manufactured by Microchip Technology. These components are widely utilized in discrete semiconductor designs requiring reliable voltage clamping or referencing capabilities in industrial and commercial electronic systems.

Replacement Considerations

Cross-reference with other manufacturers' 1N5534 equivalents ensuring identical 14 V Zener voltage, 500 mW power rating, and DO-35 package compatibility to maintain electrical performance and mechanical fit.
