SS110LH Equivalent & Substitute Parts Reference

Part Overview

The Taiwan Semiconductor Corporation SS110LH is a Schottky rectifier diode rated for 1A average rectified current and a maximum reverse voltage of 100V. Packaged as a surface-mount Sub SMA (SOD-123), the SS110LH is classified as “Not For New Designs,” indicating that ongoing production support is limited or discontinued. Identifying compatible substitute parts is required for maintaining procurement, ensuring form/fit/function continuity, and adhering to production qualification standards.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are determined based on strict matching or exceeding of the following electrical and mechanical parameters: Schottky technology, DC reverse voltage rating (100 V), average rectified current (1A), maximum forward voltage at the specified current (800 mV @ 1A), switching speed (Fast Recovery), reverse leakage current at rated voltage, surface-mount package, operating junction temperature range (-55°C ~ 150°C), RoHS and REACH compliance, and qualification level. Package compatibility and product status are included in substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

SS110LWH is the MFR recommended substitute for SS110LH. Both comply with RoHS3 and REACH, and feature identical core electrical parameters (100 V, 1A, Schottky, fast recovery). The package differs (SOD-123 vs. SOD-123W), requiring assessment for footprint compatibility. SS110LH is “Not For New Designs,” while SS110LWH is “Active,” aligning with lifecycle and compliance criteria specified.

Frequently Asked Questions (FAQ)

Q1: What are the primary substitution criteria for SS110LH?
A1: Substitution requires matching or exceeding voltage rating, current rating, maximum forward voltage at the stated current, diode technology, operating temperature range, and compliance with RoHS and REACH.

Q2: How does the package difference between SOD-123 and SOD-123W affect substitution?
A2: SOD-123 and SOD-123W are both surface-mount packages but have different mechanical outlines. Review PCB land pattern and mechanical fit when substituting between these packages.

Q3: What is the significance of automotive qualification (AEC-Q101)?
A3: SS110LH is rated for automotive (AEC-Q101). Verify automotive qualification if this grade is required for the application.

Q4: Is the reverse leakage current specification comparable between SS110LH and SS110LWH?
A4: SS110LWH has a lower maximum reverse leakage current (10 µA @ 100 V) compared to SS110LH (50 µA @ 100 V).

Q5: Is SS110LWH suitable as a replacement for new designs?
A5: SS110LWH is an “Active” part with matching electrical parameters and compliance. Package and qualification requirements should be considered based only on the specifications provided above.
