1N4697-TP

Overview

The 1N4697-TP is a silicon Zener diode from the 1N4678 through 1N4717 series manufactured by Micro Commercial Components. It provides a nominal Zener voltage of 10 V with a standard tolerance of ±5%. The device operates in a DO-35 axial leaded glass package and dissipates up to 500 mW at ambient temperatures below 75°C. Key electrical characteristics include a maximum reverse leakage current of 1 µA, a forward voltage of 1.5 V at 100 mA, and a junction temperature rating of 200°C.

Feature Summary

• Features a very sharp reverse characteristic for precise voltage regulation
• Constructed with a double slug type hermetically sealed glass case
• Includes an internal metallurgical bond for high reliability

Applications

• Voltage regulation circuits
• Reference voltage sources
• Overvoltage protection

Procurement Notes

Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors to avoid counterfeit parts. Confirm that the -TP suffix indicates tape and reel packaging containing 10,000 pieces per reel. Ensure compliance with RoHS standards and check for specific handling requirements regarding moisture sensitivity level 1.

Selection Notes

Select this component when a 10 V reference with ±5% tolerance is required in a through-hole configuration. Consider the 500 mW power dissipation limit and ensure adequate thermal management if operating near the maximum junction temperature. Verify that the DO-35 package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the 1N4678 through 1N4717 series of 500 mW silicon Zener diodes. The series covers a wide voltage range from 1.8 V to 43 V, all utilizing the same DO-35 glass package. The 1N4697 specifically targets the 10 V segment within this standardized lineup.

Replacement Considerations

Direct substitutes within the same series include other 1N46xx variants with similar power ratings. Cross-referencing with JEDEC registered equivalents is recommended for pin-compatible replacements in existing designs.
