Product details
Overview
SS110LWH from Taiwan Semiconductor is a 1A, 100V Schottky barrier surface-mount rectifier in SOD-123W package, featuring 0.80V forward voltage at 1A and 10µA reverse leakage at rated VR, designed for DC/DC converters and reverse battery protection in automotive lighting systems.
For engineers reviewing the SS110LWH datasheet, SS110LWH pinout, SS110LWH application, or SS110LWH equivalent, key selection criteria include its AEC-Q101 qualification, 100V repetitive peak reverse voltage, 30A surge capability, and thermal resistance of 25°C/W junction-to-lead - critical for high-reliability 12V/24V automotive power rails.
Technical Context
The SS110LWH implements a single-die Schottky structure with guard ring overvoltage protection and matte tin-plated leads compliant with J-STD-002 solderability. Its junction temperature rating extends to +150°C, enabling operation in under-hood environments without derating below 1A continuous current.
Thermal performance is defined by RθJL = 25°C/W and RθJA = 80°C/W, supporting conduction-limited designs where lead-frame heat sinking dominates over PCB copper area. Reverse leakage remains ≤10µA up to 100V at 25°C, ensuring low standby loss in always-on vehicle modules.

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-M3/5AT | 1A, 100V, VF = 0.72V @ 1A, IR = 100µA @ 100V, SOD-123 package | Higher leakage limits use in ultra-low-power always-on circuits | Select when lower forward drop is prioritized over leakage; verify layout compatibility with SOD-123 (vs. SOD-123W) |
| ON Semiconductor SB1100-TB | 1A, 100V, VF = 0.85V @ 1A, IR = 50µA @ 100V, SOD-123 package | Non-AEC-Q101; suitable for industrial but not automotive qualification-critical designs | Select for cost-sensitive industrial DC/DC where AEC-Q101 is not mandated |
Compared with VS-1EQH01-M3/5AT and SB1100-TB, the SS110LWH delivers lower leakage (10µA vs. ≥50µA) and automotive qualification - making it preferred for reverse-battery protection and always-on modules where leakage-induced battery drain or qualification gaps are unacceptable.

FAQ
What is the maximum junction temperature rating for the SS110LWH?
The SS110LWH has a maximum junction temperature (TJ) rating of +150°C, validated per AEC-Q101 stress test conditions. This allows uninterrupted 1A operation in under-hood environments where ambient temperatures exceed 105°C, provided thermal design maintains junction temperature within this limit. The SS110LWH achieves this via its 25°C/W junction-to-lead thermal resistance and SOD-123W package construction.
Is the SS110LWH suitable for reverse battery protection in automotive applications?
Yes, the SS110LWH is explicitly qualified for reverse battery protection in automotive systems. Its 100V VRRM, 10µA reverse leakage at rated voltage, AEC-Q101 qualification, and guard ring overvoltage protection make it suitable for safeguarding 12V and 24V ECUs against accidental reverse polarity connection. The SS110LWH is used in production automotive lighting and infotainment modules for this purpose.
What is the forward voltage of the SS110LWH at 1A and 25°C?
The SS110LWH exhibits a maximum forward voltage (VF) of 0.80 V at 1A forward current and 25°C junction temperature, measured under pulsed conditions (PW = 0.3ms). This value is confirmed in the official Taiwan Semiconductor datasheet revision B2305 and directly impacts conduction loss in DC/DC output stages - for example, resulting in 0.8W dissipation at 1A versus >1.2W for standard silicon diodes.
Does the SS110LWH have a halogen-free and RoHS-compliant construction?
Yes, the SS110LWH is both halogen-free and RoHS compliant, as stated in the Taiwan Semiconductor product documentation. The molding compound, lead finish (matte tin), and internal die materials meet EU Directive 2011/65/EU and IEC 61249-2-21 standards. This compliance is verified through material declarations and third-party testing, supporting automotive OEM sustainability requirements and end-of-life recycling protocols.
What packaging format is available for the SS110LWH?
The SS110LWH is supplied in tape-and-reel packaging, with 10,000 units per reel, compatible with automated SMT placement equipment. The SOD-123W package features J-STD-020 Level 1 moisture sensitivity, eliminating the need for pre-reflow baking. The marking code "10LW" is laser-etched on the device body, and polarity is indicated by a cathode band aligned with JEDEC DO-219AB mechanical specifications.
