SMBG5358B/TR13

Single Zener Diodes Overview

The SMBG5358B/TR13 is a surface mount silicon 5.0 watt Zener diode from the SMBG5333B through SMBG5388B series, manufactured by Microchip Technology. It provides a nominal Zener voltage of 22 V with a ±5% tolerance, indicated by the 'B' suffix. The device operates within a junction and storage temperature range of -65°C to +150°C and features a maximum dynamic impedance of 3.5 Ohms at a test current of 50 mA. It 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 axial-leaded series
• Ideal for high-density and low-profile mounting applications
• Non-sensitive to electrostatic discharge per MIL-STD-750 method 1020
• Moisture classification Level 1 requiring no dry pack

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• High surge stress withstand scenarios
• General purpose voltage reference circuits

Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin, as Microchip acquired Microsemi which originally produced this series. Confirm RoHS compliance status, as the datasheet indicates both tin-lead and matte-tin finishes are available depending on the ordering suffix. Ensure the TR suffix corresponds to the required tape and reel quantity specifications.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power rating and 22-volt regulation are required in a surface mount form factor. The ±5% tolerance suits standard precision applications. Consider the thermal resistance values for heat sinking requirements if operating near maximum power dissipation limits.

Single Zener Diodes Part Context

This part belongs to the SMBG5333B-SMBG5388B family of 5-watt Zener diodes. These devices serve as surface mount equivalents to the traditional 1N5333-1N5388B axial-leaded series, offering identical electrical characteristics while enabling automated assembly processes through their gull-wing lead frame design.

Single Zener Diodes Replacement Considerations

SMBG5358A (±10% tolerance), SMBG5358C (±2% tolerance). Equivalent axial parts include 1N5358B.
