Product details
Overview
SS1H10LS from Taiwan Semiconductor is a 1A, 100V Schottky barrier surface-mount rectifier in SOD-123HE package, featuring 0.80V forward voltage at 1A/25°C, ≤1.0µA reverse leakage at 25°C, and 30A peak surge current-designed for high-efficiency DC/DC converters in compact power adapters.
For engineers reviewing the SS1H10LS datasheet, SS1H10LS pinout, SS1H10LS application, or SS1H10LS equivalent, key selection criteria include its 100V VRRM, ultra-low profile (<0.85mm), JESD201 Class 2 whisker resistance, and moisture sensitivity level 1 compliance for automated SMT assembly.
Technical Context
This Schottky rectifier uses a single-die construction with matte tin-plated leads solderable per J-STD-002, enabling low-loss unidirectional conduction in high-frequency switching topologies. Its thermal design supports 150°C maximum junction temperature and 20°C/W junction-to-lead resistance for reliable power dissipation in space-constrained layouts.
The device operates across –55°C to +150°C storage and junction temperature ranges, with reverse current limited to 0.2mA at 125°C and rated VR-critical for stable performance in thermally demanding SMPS secondary-side rectification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-1EQH01-M3/84A | Same SOD-123HE package; 100V VRRM, 0.79V VF @ 1A, but 0.5mA IR @ 125°C (vs. 0.2mA for SS1H10LS) | Higher leakage reduces suitability for extended high-temp automotive sleep modes | Preferred where lowest VF dominates over leakage in commercial-grade adapters |
| ON Semiconductor SB1100-TB | SOD-123 package (not HE variant); 100V VRRM, 0.82V VF, 0.2mA IR @ 125°C-but 0.95mm height vs. SS1H10LS's <0.85mm | 0.1mm taller profile may violate Z-height constraints in ultra-slim designs | Select when legacy SOD-123 footprint compatibility is required over minimal profile |
Compared with VS-1EQH01-M3/84A and SB1100-TB, SS1H10LS delivers the tightest combination of ultra-low profile, industry-leading 125°C leakage (0.2mA), and MSL Level 1 handling-making it optimal for next-gen space- and thermal-constrained power stages.

FAQ
What is the maximum junction temperature rating for SS1H10LS?
The SS1H10LS has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet Version C2208. This allows continuous operation in enclosed industrial power modules where board temperatures reach 85°C and power dissipation induces additional junction rise. Derating curves confirm usable current capacity down to 0.6A at 125°C ambient.
Does SS1H10LS have a halogen-free and RoHS-compliant construction?
Yes, SS1H10LS is halogen-free per IEC 61249-2-21 and RoHS compliant, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. The molding compound, lead finish, and internal die attach materials meet both environmental standards without exemptions, supporting compliance documentation for CE, UKCA, and China RoHS submissions.
What is the forward voltage specification for SS1H10LS at 1A and 25°C?
The forward voltage (VF) for SS1H10LS is specified as a maximum of 0.80 V at IF = 1 A and TJ = 25°C, per the ELECTRICAL SPECIFICATIONS table in the official datasheet. This value is measured under pulse conditions (PW = 0.3 ms) and represents worst-case conduction loss for thermal and efficiency modeling in DC/DC output stage design.
Is SS1H10LS suitable for automated SMT placement?
Yes, SS1H10LS is explicitly designed for automated placement, as confirmed in the FEATURES section. Its SOD-123HE package meets J-STD-020 moisture sensitivity level 1, requires no pre-bake, and features matte tin-plated leads compliant with J-STD-002 solderability-ensuring high first-pass yield in high-speed pick-and-place and reflow processes.
What is the reverse leakage current of SS1H10LS at 125°C?
At TJ = 125°C and rated reverse voltage (100 V), the SS1H10LS exhibits a maximum reverse leakage current (IR) of 0.2 mA, as documented in the ELECTRICAL SPECIFICATIONS table. This value is critical for standby power budgeting in always-on applications such as smart home hubs and industrial sensors operating continuously at elevated ambient temperatures.
