1N4697/TR

Overview

The Microchip Technology 1N4697/TR is a single 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-7 (DO-204AA) through-hole package and dissipates up to 500 mW of power. Key electrical parameters include a maximum reverse leakage current of 1 uA, a test current of 50 uA, and a Zener current of 24.8 mA. It supports an operating temperature range from -65°C to +200°C.

Feature Summary

• Provides stable voltage regulation at a nominal 10 V level
• Capable of handling 500 mW power dissipation in through-hole packages
• Maintains low reverse leakage current for efficient operation

Applications

• Voltage reference circuits requiring precise 10 V levels
• Overvoltage protection in electronic systems
• General-purpose voltage regulation tasks

Procurement Notes

Verify the specific manufacturer source, as onsemi and Central Semiconductor also produce this part number. Confirm RoHS compliance status, as some variants are marked non-compliant. Ensure the tape-and-reel packaging matches assembly requirements. Check for obsolescence notices, particularly regarding onsemi production status. Validate that the DO-7 package dimensions fit the target PCB layout.

Selection Notes

Select this component when a standard 10 V Zener voltage is required with high-temperature capability up to 200°C. The DO-7 package suits through-hole mounting needs. Consider the ±5% tolerance for general regulation rather than precision references. Evaluate the 500 mW power rating against circuit load conditions. Compare leakage current specifications if low-power standby modes are critical.
