SMBG5370AE3/TR13

Single Zener Diodes Overview

The SMBG5370AE3/TR13 is a surface mount silicon Zener diode from the SMBG5333B-5388B series, manufactured by Microchip Technology. It provides a nominal Zener voltage of 56 V with a tolerance of ±10%. The device operates in a DO-215AA (SMBG) gull-wing package and offers a maximum power dissipation of 5.0 W at a lead temperature below 25°C. It features a maximum dynamic impedance of 35 Ohms and withstands a maximum surge current of 280 Amps.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges.
• Features high surge current capability to withstand transient stress events.
• Designed for high-density and low-profile mounting applications.
• Moisture classification Level 1 requires no dry pack storage.

Single Zener Diodes Applications

• Voltage regulation in electronic circuits
• High-density PCB mounting designs
• Low-profile component integration

Single Zener Diodes Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm electrical characteristics and compliance status. Ensure that the ordering suffixes match the required RoHS compliance and packaging specifications. Confirm availability and lifecycle status through authorized distribution channels prior to procurement.

Single Zener Diodes Selection Notes

Select this component when a 56 V Zener reference with ±10% tolerance is required in a surface mount configuration. Consider the 5.0 W power rating and thermal resistance values for heat sinking requirements. Verify compatibility with JEDEC registered equivalents if transitioning from axial-leaded designs.

Single Zener Diodes Part Context

This component belongs to the SMBG5333B through SMBG5388B series of surface mount 5.0 watt Zener diodes. The series is electrically equivalent to the JEDEC registered 1N5333 through 1N5388 series. The SMBG designation indicates a gull-wing lead frame design within the DO-215AA package, distinct from the J-bend SMBJ variants.

Single Zener Diodes Replacement Considerations

The SMBG5370A is functionally equivalent to the JEDEC registered 1N5370B. Other series members such as SMBG5369A or SMBG5371A may serve as alternatives if different voltage ratings are acceptable.
