1N4101UR/TR

Single Zener Diodes Overview

The Microchip Technology 1N4101UR/TR is a glass surface mount Zener voltage regulator with a nominal breakdown voltage of 8.2 V and a standard tolerance of ±5%. It operates within a power dissipation range of 0.5 W at an end-cap temperature below 100°C or ambient temperature below 25°C. The device features a maximum Zener impedance of 200 Ohms, a reverse leakage current of 1 µA at 6.24 V, and a typical temperature coefficient of 0.048 %/°C. It utilizes a hermetically sealed DO-213AA (SOD80) package and supports tape-and-reel packaging.

Single Zener Diodes Feature Summary

• Hermetically sealed glass DO-213AA MELF-style surface mount package
• Internal metallurgical bond construction for enhanced reliability
• Inherently radiation hard design suitable for harsh environments
• ESD non-sensitive per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation in broad operating current ranges
• Reference voltage sources in precision circuits
• Protection against overvoltage transients
• Radiation-hardened electronic systems

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix to confirm the presence of the tape-and-reel configuration. Ensure that the required voltage tolerance aligns with the standard ±5% specification unless tighter tolerances are explicitly requested via alternative suffixes. Confirm RoHS compliance status based on the final part number designation before procurement.

Single Zener Diodes Selection Notes

Select this component when a compact surface mount solution is required for stable voltage regulation. The DO-213AA package offers a direct footprint equivalent to traditional axial leads while providing hermetic sealing. Consider the thermal resistance characteristics and derating curves when designing for high ambient temperatures or limited board space.

Single Zener Diodes Part Context

This device belongs to the 1N4099UR through 1N4135UR series of 0.5-watt glass Zener diodes manufactured by Microsemi (now Microchip Technology). The series provides a wide selection of voltages from 1.8 V to 100 V in a standardized surface mount form factor compatible with JEDEC registered equivalents.

Single Zener Diodes Replacement Considerations

Direct replacements include other manufacturers' DO-213AA Zener diodes with matching 8.2 V ratings and 0.5 W power dissipation. Verify that substitute components meet the same hermetic sealing requirements and radiation hardness specifications if used in critical applications.

Single Zener Diodes FAQ

What is the maximum steady-state power dissipation?

The maximum steady-state power dissipation is 0.5 watts, provided the end-cap temperature remains below 100°C or the ambient temperature is below 25°C.

Is the device sensitive to electrostatic discharge?

No, the device is not sensitive to ESD, as verified by MIL-STD-750 Method 1020 testing.
