SMBJ5914A/TR13

Single Zener Diodes Overview

The SMBJ5914A/TR13 is a surface mount 2.0 W Zener diode from the SMBJ59 family, equivalent to JEDEC registered 1N5918–1N5924 series components. It features a DO-214AA (SMB) J-bend package for high-density mounting and operates within a junction temperature range of -65 °C to +150 °C. The device provides a nominal Zener voltage of 7.5 V with a ±5% tolerance (range 7.13 V to 7.88 V). Key electrical parameters include a maximum dynamic impedance of 50.0 Ω at IZT = 6.0 mA, a maximum knee impedance of 400 Ω at IZK = 0.5 mA, and a maximum reverse leakage current of 0.5 µA at VR = 5.0 V. The maximum regulator current (IZM) is rated at 266 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features low thermal resistance design allowing operation at high DC currents with adequate heat sinking
• Non-sensitive to electrostatic discharge per MIL-STD-750 method 1020
• Moisture classification Level 1 requiring no dry pack storage

Single Zener Diodes Applications

• Voltage regulation in circuits requiring robust surge stress withstand capability
• High-density PCB mounting applications utilizing the low-profile SMB package
• General purpose voltage reference or protection where minimal voltage change versus current is required

Single Zener Diodes Procurement Notes

Verify that the specific part number suffix matches the required plating option, as the datasheet indicates availability with either SnPb plated or RoHS compliant matte-tin plating options. Confirm the 'TR' suffix corresponds to the tape and reel packaging format specified in the mechanical packaging section. Ensure procurement documentation aligns with the manufacturer's current revision history DS00005783A.

Single Zener Diodes Selection Notes

Select this component when a 2.0 W power rating is necessary for surface mount applications, offering a 30% higher rating compared to axial equivalents. Choose the A suffix variant specifically for the ±5% voltage tolerance requirement. Consider the DO-214AA package dimensions for footprint compatibility and verify thermal management requirements against the junction-to-ambient thermal resistance specifications provided in the maximum ratings table.

Single Zener Diodes Part Context

This component belongs to the SMBJ59 family of silicon 2.0 Watt Zener diodes manufactured by Microchip Technology. The family covers Zener voltages from 5.1 V to 9.1 V and serves as a surface mount alternative to the older SMS package and axial 1N5918–1N5924 series. The SMBJ5914A represents the 7.5 V nominal voltage variant within this specific product line.
