1N4714 (DO35)

Overview

The Microsemi 1N4714 is a silicon Zener diode housed in the DO-35 (DO-204AH) glass axial-leaded package. It features a nominal Zener voltage of 5.6 V with a standard tolerance of ±5%. The device is rated for a maximum DC power dissipation of 500 mW at +50°C, with a derating factor of 4 mW/°C above this temperature. It operates within a junction temperature range of -65°C to +175°C and includes a maximum reverse leakage current specification of 10 µA at 25°C.

Feature Summary

• Provides stable voltage regulation via Zener breakdown characteristics
• Constructed with hermetically sealed glass body for environmental protection
• Capable of operation across extended industrial and military temperature ranges

Applications

• General-purpose voltage reference circuits
• Overvoltage protection stages
• Biasing networks in analog signal processing

Procurement Notes

Verify the specific suffix codes on the component marking to confirm exact tolerance grades and qualification levels. Standard commercial versions differ from military-qualified variants such as JAN or JANTX. Confirm RoHS compliance status if required by assembly specifications. Cross-reference datasheet revisions to ensure parameter consistency with design requirements.

Selection Notes

Select the 1N4714 when a precise 5.6 V reference is needed in a compact axial package. Consider the 500 mW power limit and thermal derating curves for high-temperature environments. Evaluate dynamic impedance specifications if low noise or tight regulation under varying load currents is critical for the application stability.

Part Context

This component belongs to the JEDEC registered 1N47xx series of 500 mW Zener diodes. These devices are widely used in discrete semiconductor applications requiring reliable voltage clamping. The DO-35 package offers a balance of performance and ease of through-hole mounting for various electronic assemblies.

Replacement Considerations

Equivalent parts include other manufacturers' 1N4714 variants. Surface mount equivalents exist in MELF packages such as MLL4714. Ensure replacement devices match the 5.6 V nominal voltage and 500 mW power rating.
