SMBJ5350AE3/TR13

Single Zener Diodes Overview

The SMBJ5350AE3/TR13 is a surface mount silicon 5.0 watt Zener diode manufactured by Microchip Technology. It provides a nominal breakdown voltage of 13 V with a tolerance of +/- 5%. The device operates within a junction and storage temperature range of -65 °C to +150 °C. It features a maximum dynamic impedance of 2.5 Ohms at a test current of 100 mA, with a maximum reverse current of 1.0 µA tested at 9.4 V. The component utilizes a DO-215AA gull-wing package and is supplied in tape and reel packaging.

Single Zener Diodes Feature Summary

• Surface mount equivalent to JEDEC registered 1N5333 thru 1N5388 series
• Ideal for high-density and low-profile mounting
• Non-sensitive to ESD per MIL-STD-750 method 1020
• Withstands high surge stresses

Single Zener Diodes Applications

• Regulates voltage over broad operating current and temperature ranges
• Provides wide selection from 3.3 to 200 V
• Minimal changes of voltage versus current

Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin, as the SMBG series datasheet originates from Microsemi Corporation, which has undergone corporate restructuring. Confirm that the 'e3' suffix denotes RoHS compliance and matte-tin plating finish. Ensure the 'TR' suffix matches the required tape and reel packaging format. Validate the part number against current Microchip Technology catalogs to confirm availability status and any potential obsolescence notifications.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power rating is required for voltage regulation applications. The DO-215AA gull-wing package allows for visible solder connections, facilitating inspection. Choose the '+/- 5%' tolerance variant (suffix 'B') if tighter voltage accuracy is needed compared to the standard 10% option. Ensure adequate heat sinking is provided to maintain operation within the specified thermal resistance limits.

Single Zener Diodes Part Context

This component belongs to the SMBG5333B through SMBG5388B series of surface mount 5.0 watt Zener diodes. It serves as the surface mount equivalent to the JEDEC registered 1N5333 through 1N5388 axial-leaded series, sharing identical electrical characteristics. The series offers a voltage selection from 3.3 V to 200 V with various tolerance options including 10%, 5%, and 2%.

Single Zener Diodes Replacement Considerations

Direct substitutes include the non-surface mount equivalent 1N5350BE3 or other SMBJ5350 variants from different manufacturers. Verify pinout compatibility and thermal performance before substitution.
