Product details
Overview
SS110FSH from Taiwan Semiconductor is a 1A, 100V Schottky barrier surface-mount rectifier in SOD-128 package, featuring low forward voltage (0.75 V at 1.0 A, 25°C), low reverse leakage (10 µA at 25°C), and high surge capability (30 A IFSM). It serves as a primary output rectifier in compact DC/DC converters for automotive infotainment systems.
For engineers reviewing the SS110FSH datasheet, SS110FSH pinout, SS110FSH application, or SS110FSH equivalent, key selection criteria include its 100V VRRM rating, thermal resistance (RθJA = 75°C/W on 5mm × 5mm Cu pad), AEC-Q101 qualification, and SOD-128 footprint compatibility with automated placement processes.
Technical Context
The SS110FSH operates as a single-die, unidirectional Schottky rectifier optimized for high-frequency switching applications. Its junction capacitance of 36 pF at 1 MHz and 4.0 V reverse bias supports fast recovery in SMPS topologies, while its 150°C maximum junction temperature enables operation in thermally constrained automotive environments.
Thermal performance is defined by RθJL = 20°C/W and RθJC = 18°C/W, measured on standard PCB test board (5 mm × 5 mm Cu pad). The device uses matte tin-plated leads compliant with J-STD-002 solderability and meets JESD201 Class 2 whisker resistance.

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-1EWH01-M3/5AT | Same 100 V VRRM, 1 A IF, but SOD-123FL package; RθJA = 125°C/W (higher thermal resistance) | Less suitable for high-power-density designs due to inferior thermal dissipation | Prefer SS110FSH where board space permits SOD-128 and thermal margin is critical |
| ON Semiconductor SB1100-TB | 100 V VRRM, 1 A IF, SOD-123 package; VF = 0.82 V (max) at 1 A, 25°C - higher conduction loss | Higher VF increases heat generation in continuous 1 A operation | SS110FSH offers 7 mV lower typical VF and AEC-Q101 qualification not present in SB1100-TB |
Compared with VS-1EWH01-M3/5AT and SB1100-TB, the SS110FSH delivers superior thermal performance (RθJA = 75°C/W vs. ≥125°C/W), lower forward voltage, and automotive-grade qualification-making it optimal for thermally demanding, safety-conscious designs where reliability and efficiency are co-prioritized.

FAQ
What is the maximum junction temperature rating for SS110FSH?
The SS110FSH has a maximum junction temperature (TJ MAX) of +150°C, validated per AEC-Q101 stress testing. This rating allows reliable operation in under-hood automotive environments and enclosed industrial enclosures when mounted on a 5 mm × 5 mm copper pad. Derating curves in the SS110FSH datasheet confirm 1 A continuous current is sustainable up to 125°C ambient with appropriate PCB thermal design.
Is SS110FSH suitable for use in automotive applications?
Yes, the SS110FSH is AEC-Q101 qualified and explicitly rated for automotive use. Its qualification includes temperature cycling, high-temperature reverse bias (HTRB), and mechanical shock testing per the AEC standard. The device is deployed in automotive infotainment power supplies and body control modules where 100 V blocking and 1 A output capability are required.
What is the forward voltage of SS110FSH at 1 A and 125°C?
The SS110FSH exhibits a forward voltage of 0.60 V (typical) and 0.67 V (maximum) at 1.0 A and TJ = 125°C. This reduced VF versus room-temperature operation reflects the negative temperature coefficient of Schottky diodes and supports stable performance in thermally elevated operating conditions such as engine bay-mounted power supplies.
Does SS110FSH have halogen-free and RoHS-compliant construction?
Yes, the SS110FSH is both RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, eliminating corrosive decomposition products during reflow soldering or long-term field operation-critical for high-reliability automotive and industrial deployments.
What is the moisture sensitivity level (MSL) of SS110FSH?
The SS110FSH has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it has unlimited floor life and does not require dry-packaging or baking prior to surface-mount reflow. This simplifies manufacturing logistics and eliminates risk of popcorning during standard lead-free reflow profiles.
