1N4697

Overview

The Motorola 1N4697 is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 10 V with a tolerance of 5%. The device operates in the DO-35 axial leaded package, suitable for through-hole mounting. It supports a maximum steady-state power dissipation of 500 mW at ambient temperatures up to 75°C, with derating required above this threshold. The component maintains an operating temperature range from -65°C to +200°C and exhibits a maximum reverse leakage current of 1 µA.

Feature Summary

• Utilizes double slug type construction for robust performance
• Features metallurgically bonded construction for reliability
• Provides hermetically sealed glass encapsulation

Applications

• Voltage regulation circuits
• Reference voltage sources
• Overvoltage protection

Procurement Notes

Verify manufacturer origin as historical Motorola documentation may be licensed or transferred. Confirm specific lot markings and revision levels against current datasheets. Ensure compliance with environmental directives if required by the end application. Check availability status as legacy components may have limited supply chains.

Selection Notes

Select based on the 10 V nominal voltage requirement and 5% tolerance accuracy. Ensure the circuit design accommodates the 500 mW power dissipation limit and appropriate thermal management. Verify that the DO-35 package dimensions fit the PCB layout constraints. Consider the wide operating temperature range for extreme environment suitability.

Part Context

This component belongs to the standard Zener diode family used for precise voltage control. It represents a legacy semiconductor product originally manufactured by Motorola, now potentially managed by other entities holding the rights. The DO-35 package is a standard industry form factor for low-power axial diodes.

Replacement Considerations

Cross-reference with equivalent part numbers from other manufacturers offering 10 V, 500 mW Zener diodes in DO-35 packages. Verify pinout compatibility and electrical parameter equivalence before substitution.
