SMBJ5935A/TR13 Equivalent & Substitute Zener Diode Parts Reference

Part Overview

The SMBJ5935A/TR13, manufactured by Microchip Technology, is a surface-mount Zener diode designed for voltage regulation and surge protection applications. It provides a Zener nominal voltage of 27 V with ±10% tolerance, a maximum power dissipation of 2 W, and is packaged in a DO-214AA (SMBJ) form factor. The product is classified as active, but alternative part identification is often necessary due to factors such as RoHS compliance requirements, inventory management, or supply chain continuity. This reference page identifies and compares alternative parts within the same product and package category for engineering use.

Substitute Part Grouping Explanation

Substitute parts are selected strictly based on matching electrical and mechanical parameters: Zener voltage (27 V), case/package (DO-214AA, SMB), maximum impedance (23 Ohms), reverse leakage (1 µA @ 20.6 V), and operating temperature (-65°C ~ 150°C). Tolerance, maximum power dissipation, mounting type, and RoHS/REACH compliance status are also considered. Only parts explicitly matching these parameters in the provided data are listed as substitutes.
