1N4133UR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N4133UR-1/TR is a glass surface mount Zener voltage regulator with a nominal breakdown voltage of 87 V. It operates within the 1N4099UR through 1N4135UR series and utilizes a hermetically sealed DO-213AA package. The device provides a steady-state power dissipation of 0.5 watts at an end cap temperature below 100°C or ambient temperature below 25°C. Electrical characteristics include a maximum reverse current of 1 µA, a zener impedance of 1000 Ohms, and a typical voltage temperature coefficient of 0.095 %/°C.

Single Zener Diodes Procurement Notes

Verify that the part number suffix indicates the internal metallurgical bond option (-1) and tape-and-reel packaging (TR). Confirm the manufacturer designation as Microchip Technology or Microsemi. Ensure compliance with MIL-PRF-19500/435 standards if military qualification is required. Cross-reference the specific tolerance requirements against the datasheet electrical characteristics table.

Single Zener Diodes Selection Notes

Select this component when a surface mount equivalent to the axial-leaded 1N4133 is required. The -1 suffix denotes the internal metallurgical bond necessary for high-reliability environments. Verify that the 87 V nominal voltage aligns with circuit design specifications. Consider the 0.5 W power rating and thermal resistance values for proper heat dissipation on FR4 printed circuit boards.

Single Zener Diodes Part Context

This device belongs to the 1N4099UR through 1N4135UR series of 0.5 watt glass surface mount Zener diodes. These components serve as surface mount equivalents to JEDEC registered axial-leaded parts. The series offers voltages from 1.8 to 100 V with standard 5% tolerances. The -1 suffix specifically identifies versions with internal metallurgical bonds suitable for JAN, JANTX, and JANTXV qualifications.
