SMBG5337AE3/TR13

Single Zener Diodes Overview

The SMBG5337AE3/TR13 is a surface mount silicon Zener diode from the SMBG5333B-5388B series, manufactured by Microsemi Corporation. It provides a nominal Zener voltage of 4.7 V with a ±10% tolerance and a maximum power dissipation of 5.0 W at 25 °C. The device utilizes a DO-215AA gull-wing package for visible solder connections and operates within a junction temperature range of -65 °C to +150 °C. It features a maximum reverse current of 10 µA at 1.0 V and a dynamic impedance of 2.0 Ω.

Single Zener Diodes Procurement Notes

Verify component authenticity by checking for the specific suffix 'e3' indicating RoHS compliance and 'TR13' denoting tape and reel packaging. Confirm that the part number matches the official Microsemi nomenclature structure. Ensure the supplier provides documentation verifying the gull-wing lead frame configuration in the DO-215AA package. Cross-reference the manufacturer's discontinuance notifications if applicable.

Single Zener Diodes Selection Notes

Select this component when a 5-watt surface mount Zener diode is required for applications needing robust surge handling and wide temperature operation. The gull-wing design facilitates visual inspection of solder joints compared to J-bend alternatives. Consider the ±10% voltage tolerance and specific test currents when designing circuits that demand precise regulation characteristics under varying thermal conditions.

Single Zener Diodes Part Context

This device belongs to the SMBG5333B through SMBG5388B series of 5.0 watt surface mount Zener diodes. It serves as a plastic encapsulated alternative to traditional axial-leaded components while maintaining identical electrical characteristics. The series offers a selection of voltages from 3.3 V to 200 V, catering to diverse voltage regulation needs in compact electronic designs.

Single Zener Diodes Replacement Considerations

Equivalent parts include the non-RoHS SMBG5337A and the J-bend variant SMBJ5337A. For axial-leaded requirements, the 1N5337B is electrically equivalent. Verify package compatibility and lead configuration before substituting.
