SMBG5344BE3/TR13

Single Zener Diodes Overview

The SMBG5344BE3/TR13 is a surface mount silicon Zener diode with a nominal breakdown voltage of 8.2 V and a maximum power dissipation of 5 W at lead temperatures below 25 °C. It features a ±5% voltage tolerance, a maximum dynamic impedance of 1.5 Ohms, and a reverse leakage current of 10 µA at 5.9 V. The device operates within a junction temperature range of -65 °C to +150 °C and utilizes a DO-215AA gull-wing package.

Single Zener Diodes Feature Summary

• Surface mount design equivalent to JEDEC registered 1N5333 through 1N5388 series for high-density mounting.
• RoHS compliant matte-tin finish available on gull-wing leads.
• Moisture classification Level 1 requiring no dry pack storage.

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges.
• Protection against high surge stresses in electronic circuits.
• ESD protection applications non-sensitive per MIL-STD-750 method 1020.

Single Zener Diodes Procurement Notes

Verify the specific suffix 'B' indicates a ±5% tolerance and 'e3' confirms RoHS compliance before procurement. Confirm the 'TR13' designation corresponds to tape and reel packaging standards. Check for discontinuance notifications as Microsemi products may have limited availability or end-of-life status.

Single Zener Diodes Selection Notes

Select this component when a 5 W surface mount Zener diode with an 8.2 V breakdown voltage is required. Ensure the application supports the specified thermal resistance values and operates within the -65 °C to +150 °C temperature range. Verify that the ±5% tolerance meets the circuit's precision requirements.

Single Zener Diodes Part Context

This part belongs to the SMBG5333B through SMBG5388B series of 5.0 watt Zener diodes manufactured by Microchip Technology (formerly Microsemi). The series offers a wide selection of voltages from 3.3 V to 200 V with various tolerance options, providing a robust alternative to traditional axial-leaded packages in surface mount designs.

Single Zener Diodes Replacement Considerations

Direct equivalents include the SMBJ5344B series in the J-bend package and the 1N5344B in the T-18 axial package, provided electrical characteristics match the application requirements.
