Equivalent & Substitute Parts Reference for SS25LH

Part Overview

The SS25LH is a Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, categorized as a surface-mount rectifier (Diodes, Rectifiers category). It features a maximum reverse voltage of 50 V, an average rectified current of 2A, and a fast recovery time, making it suitable for high-speed rectification applications. It is supplied in the SOD-123 (Sub SMA) package for tape & reel mounting. The SS25LH is designated as “Not For New Designs,” making it necessary to identify and utilize alternative models for continued support in new product development or ongoing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts must match or exceed the electrical specifications and maintain package compatibility for direct replacement in existing designs. The key parameters for substitution are: Schottky technology, equal or higher maximum reverse voltage (Vr), equal or greater average rectified current (Io), equal or lower maximum forward voltage (Vf) at the rated current, similar or better speed, equal or lower reverse leakage at maximum reverse voltage, identical or compatible mounting type, compatible package/case, and the same or wider operating temperature range. All compliance statuses must align with industry requirements.

Parameter Comparison

Engineering Selection Recommendations

The SS25LH is classified as “Not For New Designs.” The SS26LWH maintains an active product status and shares compliance certifications, including ROHS3 and REACH unaffected designations. Substitute part selection should be based on product status and compliance alignment. No additional selection criteria are introduced beyond those provided.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to select a substitute for SS25LH?
A1: Substitutes must match or exceed the main electrical parameters, including Schottky technology, maximum reverse voltage, current rating, forward voltage at the specified current, switching speed, reverse leakage, mounting type, package compatibility, and compliance certifications.

Q2: Is the package SOD-123W used by SS26LWH compatible with SOD-123 and Sub SMA?
A2: Both SOD-123 and SOD-123W are surface-mount packages with similar form factors but may vary in footprint specifics. Package compatibility should be evaluated strictly based on the provided package type.

Q3: Do both SS25LH and its substitute SS26LWH meet environmental compliance requirements?
A3: Both parts are ROHS3 compliant and REACH unaffected.

Q4: Can the higher reverse voltage rating of SS26LWH (60 V) be used in place of SS25LH (50 V)?
A4: Substitution is allowed when the reverse voltage of the substitute is greater than or equal to the main part.

Q5: What is the impact of ‘Not For New Designs’ status for SS25LH?
A5: This status indicates that SS25LH should not be used in new designs, and only substitute parts with active status and matching compliance should be used for new or ongoing projects.
