1N4107UR/TR

Single Zener Diodes Overview

The Microchip Technology 1N4107UR/TR is a glass surface mount Zener voltage regulator with a nominal breakdown voltage of 13 V. It operates within a power dissipation rating of 0.5 W and maintains a standard tolerance of ±5%. The device features a maximum reverse leakage current of 40 nA at the test voltage, a typical impedance of 200 Ohms, and a temperature coefficient of 0.065 %/°C. Packaged in a hermetically sealed DO-213AA (SOD80) MELF style case, it supports an operating temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass DO-213AA MELF package
• Internal metallurgical bond option available via suffix
• Minimal capacitance for high-frequency stability
• Radiation hard design per Microsemi MicroNote 050

Single Zener Diodes Applications

• Voltage regulation in broad operating current ranges
• Temperature-compensated reference diodes
• Protection against electrostatic discharge events

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix to confirm the presence of the tape and reel packaging configuration. Ensure the required voltage tolerance aligns with the standard ±5% specification unless tighter tolerances are explicitly requested. Confirm that the RoHS compliant status matches project requirements by checking for the appropriate material designation suffix on the final part number.

Single Zener Diodes Selection Notes

Select this component when a surface mount equivalent to the JEDEC registered 1N4107 axial leaded series is required. The DO-213AA package provides a compact footprint suitable for automated assembly processes. Consider the radiation hardness characteristics if the application involves environments susceptible to ionizing radiation exposure.

Single Zener Diodes Part Context

This device belongs to the 1N4099UR through 1N4135UR series of 0.5 watt glass surface mount Zener regulators. It serves as the surface mount counterpart to the traditional DO-7 or DO-35 axial-leaded components, offering identical electrical performance in a smaller form factor designed for modern PCB layouts.

Single Zener Diodes FAQ

How is the cathode polarity indicated on the 1N4107UR/TR?

The cathode is indicated by a band on the glass body. For Zener regulation operation, the banded end must be connected positive with respect to the opposite end.

What is the thermal resistance specification for this device?

The thermal resistance is 150 °C/W junction to end cap and 300 °C/W junction to ambient when mounted on an FR4 PC board with a recommended footprint.
