1N4692UR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N4692UR-1/TR is a surface mount Zener diode with a nominal voltage of 6.8 V and a standard tolerance of ±5%. It operates within a junction temperature range of -65°C to +175°C and features a maximum steady-state power dissipation of 0.5 W. The device utilizes a hermetically sealed glass DO-213AA (MELF) package with end-cap terminals. Electrical characteristics include a Zener test current of 50 µA, a maximum reverse leakage current of 10.0 µA at the specified voltage, and a maximum DC Zener current of 70 mA.

Single Zener Diodes Feature Summary

• Hermetically sealed glass MELF package for environmental protection
• Internal metallurgical bond between metal slugs and silicon die
• High reliability construction suitable for demanding environments
• Tape and reel packaging option available

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• ESD protection circuits
• Radiation-hardened electronic systems

Single Zener Diodes Procurement Notes

Verify that the specific part number includes the TR suffix to confirm tape and reel packaging configuration. Ensure compatibility with MIL-PRF-19500 screening requirements if high-reliability standards are mandated. Confirm RoHS compliance status based on the commercial grade designation, as this affects terminal plating options.

Single Zener Diodes Selection Notes

Select this component when a 6.8 V reference is required in a surface mount form factor. Consider the 50 µA test current for low-power applications. Evaluate the thermal resistance values against the expected ambient conditions to ensure the 0.5 W power rating remains within safe operating limits during continuous operation.

Single Zener Diodes Part Context

This device belongs to the 1N4678UR-1 through 1N4717UR-1 series of 0.5 watt glass surface mount Zener voltage regulators. The series provides voltage selections from 1.8 to 43 volts. The 1N4692UR-1 specifically corresponds to the 6.8 V variant within this standardized JEDEC registered lineup.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N4692UR-1 without the TR suffix for bulk packaging or the 1N4692CUR-1 for tighter voltage tolerances.
