SMBG5374C/TR13

Single Zener Diodes Overview

The SMBG5374C/TR13 is a surface mount silicon Zener diode from the SMBG5333B through SMBG5388B series, manufactured by Microchip Technology. It features a gull-wing lead frame in the DO-215AA package and provides a nominal Zener voltage of 75 V with a tight tolerance of ±2%. The device is rated for a maximum power dissipation of 5.0 W at a lead temperature below 25°C and operates within a junction and storage temperature range of -65°C to +150°C. It includes a tape and reel option indicated by the TR suffix.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a ±2% breakdown voltage tolerance.
• Features a gull-wing design allowing for visible solder connections.
• Offers high surge current withstand capability.
• Moisture classification is Level 1, requiring no dry pack.

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges.
• High-density and low-profile mounting applications.
• Protection against high surge stresses.

Single Zener Diodes Procurement Notes

Verify component authenticity and datasheet alignment before procurement. Confirm that the specific C suffix corresponds to the required ±2% tolerance. Check RoHS compliance status as versions are available with either matte-tin or tin-lead plating. Ensure thermal management meets the specified power derating requirements for the intended mounting footprint.

Single Zener Diodes Selection Notes

Select this component when a 75 V reference requires tighter than standard tolerance. Verify that the PCB layout accommodates the DO-215AA gull-wing footprint. Consider thermal resistance values for heat sinking if operating near maximum power limits. Compare dynamic impedance specifications against circuit sensitivity requirements.

Single Zener Diodes Part Context

This part belongs to the SMBG5333B through SMBG5388B series of 5.0 watt surface mount Zener diodes. It serves as a surface mount equivalent to the JEDEC registered 1N5374 axial-leaded diode. The series covers a wide selection of voltages from 3.3 V to 200 V with various tolerance options identified by suffix letters.
