Equivalent & Substitute Parts for UFS520JE3/TR13

Part Overview

The Microchip Technology UFS520JE3/TR13 is a general-purpose diode in the Diodes, Rectifiers category. It is specified for 200 V DC reverse voltage, 5 A average rectified current, and comes in a DO-214AB (SMC) surface-mount package. This device features fast recovery characteristics with a reverse recovery time (trr) of 30 ns and a maximum forward voltage (Vf) of 950 mV at 5 A. The product is currently active and compliant with RoHS3 and REACH. When engineering designs require fulfillment, qualification, or second sourcing—such as in cases of procurement risk, supply chain shortages, or product lifecycle changes—it is necessary to identify alternative models with matching electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitutes for UFS520JE3/TR13 are determined strictly based on the following allowed parameters: category (Diodes, Rectifiers), technology (Standard), voltage - DC reverse (Vr) rating, current - average rectified (Io), maximum forward voltage (Vf) at specified current, speed (recovery type and reverse recovery time), reverse leakage current at rated voltage, mounting type (Surface Mount), package/case (DO-214AB, SMC), and compliance status. Only those parts matching these electrical and mechanical parameters are considered valid alternatives.

Engineering Selection Recommendations

When selecting substitute rectifier diodes in the DO-214AB (SMC) package, only parts with active product status, ROHS3 compliance, MSL 1, and REACH unaffected designation as specified are eligible per the provided information. Main differences, such as product status "Not For New Designs," should be considered according to the allowed usage in the intended application.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for selecting an equivalent or substitute for UFS520JE3/TR13?
A1: Key criteria include identical or higher voltage rating (Vr), current rating (Io), similar or better forward voltage (Vf) at the target current, speed (recovery time trr and type), equivalent or lower reverse leakage, identical mounting type and package, as well as the same RoHS3 and REACH compliance.

Q2: Do substitute parts need to match the physical package?
A2: Yes. All substitute parts listed share the DO-214AB (SMC) package and are surface-mount devices, ensuring mechanical compatibility.

Q3: Are all listed parts suitable for use in new designs?
A3: Not all substitutes have "Active" product status. Parts marked as "Not For New Designs" are generally used for maintenance or legacy design continuity per product lifecycle considerations.

Q4: How important is recovery time and speed in substitution?
A4: The main part features fast recovery (≤500 ns), and only substitutes with matching type (fast or standard) and closely related recovery times are considered.

Q5: Does compliance matter when substituting?
A5: Yes. Only parts that are explicitly ROHS3 compliant, MSL 1, and REACH unaffected are listed, ensuring compliance with regulatory and environmental requirements.
