SMBJ5369B-TP

Single Zener Diodes Overview

The SMBJ5369B-TP is a 5.0 W surface-mount silicon Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 51 V with a ±5% tolerance, housed in the low-profile DO-214AA (SMB) package. The device operates within a junction temperature range of -55°C to +150°C and exhibits a maximum dynamic impedance of 27 Ω at the test current of 25 mA. It includes a maximum reverse leakage current of 0.5 µA at 38.8 V and supports a maximum steady-state surge current of 0.9 A.

Single Zener Diodes Procurement Notes

Verify authenticity through authorized MCC distributors or direct purchase from Micro Commercial Components Corp. to avoid counterfeit parts. Ensure compliance with RoHS directives and confirm the specific tape and reel packaging quantity of 3000 pieces per reel matches project requirements before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 51 V reference or clamp is required in a compact surface-mount layout. The DO-214AA package accommodates space-constrained designs while providing robust thermal dissipation up to 5.0 W. Verify that the 27 Ω dynamic impedance meets the circuit's noise and stability specifications under expected operating currents.

Single Zener Diodes Part Context

This part belongs to the SMBJ5338B through SMBJ5388B series of 5.0 W Zener diodes. The series covers a wide voltage range from 5.1 V to 200 V, all sharing identical physical dimensions and thermal characteristics. The "TP" suffix indicates the standard tape and reel packaging format used for automated assembly processes.

Single Zener Diodes FAQ

What is the marking code on the SMBJ5369B-TP device?

The device marking is "369B," which corresponds to the last three digits of the part number.

How is the maximum Zener current calculated for this device?

The maximum Zener current (IZM) is derived using the formula IZM = P / VZM, where P is the rated power and VZM is the Zener voltage at the high end of the specified tolerance.
