SMAJ5919CE3/TR13

Single Zener Diodes Overview

The SMAJ5919CE3/TR13 is a single Zener diode manufactured by Microchip Technology, designed for surface-mount applications. It features a nominal Zener voltage of 5.6 V with a tight tolerance of ±2%. The device is rated for a maximum power dissipation of 3 W and utilizes the DO-214AC (SMA) package. Key electrical characteristics include a maximum reverse leakage current of 5 µA at the rated voltage and a Zener impedance of 2 Ω. It operates within a temperature range of -65 °C to +175 °C and is supplied in a reel packaging format.

Single Zener Diodes Feature Summary

• Surface-mount design compatible with high-density mounting requirements
• Tight voltage tolerance of ±2% for precise regulation
• High thermal stability supporting operation up to 175 °C

Single Zener Diodes Applications

• Voltage reference circuits requiring stable 5.6 V levels
• Overvoltage protection in compact electronic assemblies
• Clamping applications in signal conditioning paths

Single Zener Diodes Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified agents. Confirm the specific suffix CE3 indicates lead-free compliance and TR13 denotes tape-and-reel packaging. Request official datasheets and certificates of conformity prior to purchase to ensure alignment with project specifications and regulatory standards.

Single Zener Diodes Selection Notes

Select this component when a 5.6 V Zener diode with ±2% tolerance and 3 W power rating is required in an SMA package. Ensure the application environment supports the specified operating temperature range. Verify that the circuit current limits do not exceed the device's maximum ratings to maintain reliability and performance under steady-state conditions.

Single Zener Diodes Part Context

This part belongs to Microchip's SMAJ series of Zener diodes, which are surface-mount equivalents to the traditional 1N5913 through 1N5956B axial leaded devices. The series offers various voltage options from 3.3 V to 200 V, providing designers with standardized solutions for voltage regulation and protection in modern PCB layouts.

Single Zener Diodes Replacement Considerations

Direct replacements include the SMAJ5919E3/TR13 variant. Designers should verify pinout compatibility and thermal characteristics when substituting with other manufacturers' SMA-package Zener diodes offering identical 5.6 V and 3 W ratings.
