Product details
Overview
SS1H6LS from Taiwan Semiconductor is a 1A, 60V Schottky barrier surface-mount rectifier in SOD-123HE package, featuring 0.70V max forward voltage at 1A and 1.0µA max reverse leakage at 25°C, optimized for high-efficiency DC/DC converters and AC/DC adapters.
For engineers reviewing the SS1H6LS datasheet, SS1H6LS pinout, SS1H6LS application, or SS1H6LS equivalent, key selection criteria include its 60V VRRM, 30A IFSM, 20°C/W RθJL, ultra-low leakage, and compact SOD-123HE footprint with cathode band polarity marking.
Technical Context
The SS1H6LS employs a single-die Schottky junction structure enabling low forward voltage drop and fast switching with no minority-carrier recovery. Its thermal design supports 150°C maximum junction temperature and 72°C/W junction-to-ambient resistance under standard PCB mounting.
Rated for repetitive peak reverse voltage of 60V and RMS reverse voltage of 42V, it delivers stable performance across -55°C to +150°C operating and storage ranges while meeting JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity requirements.

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-1EQH06-M3/5AT | Same 60V VRRM, 1A IF, but SOD-123 package (not HE); RθJA = 100°C/W vs. 72°C/W | Lower thermal performance limits power density in high-ambient designs | Prefer SS1H6LS where board space and thermal headroom are constrained |

FAQ
What is the maximum junction temperature rating for SS1H6LS?
The SS1H6LS has a maximum junction temperature (TJ) rating of +150°C, allowing reliable operation in thermally demanding environments such as enclosed power supplies or high-ambient industrial settings. This rating is supported by its 20°C/W junction-to-lead thermal resistance and SOD-123HE package construction. Derating curves confirm usable current capacity down to -55°C ambient.
Does SS1H6LS have a halogen-free and RoHS-compliant construction?
Yes, the SS1H6LS is both halogen-free per IEC 61249-2-21 and RoHS compliant. Its molding compound meets UL 94V-0 flammability standards, and its matte tin-plated leads satisfy J-STD-002 solderability requirements. These attributes make SS1H6LS suitable for environmentally regulated end equipment including consumer electronics and industrial controls.
What is the forward voltage specification of SS1H6LS at rated current?
The SS1H6LS exhibits a maximum forward voltage (VF) of 0.70 V at 1A forward current and 25°C junction temperature, measured under pulse conditions (PW = 0.3ms). This low VF directly reduces conduction losses in high-frequency switching applications, contributing to improved system efficiency and reduced thermal stress compared to higher-VF alternatives.
How is polarity marked on the SS1H6LS device?
Polarity on the SS1H6LS is indicated by a cathode band printed on the body of the SOD-123HE package. The banded end corresponds to the cathode terminal, while the opposite end is the anode. This marking aligns with industry-standard diode polarity conventions and supports automated optical inspection during SMT assembly.
What packaging and reel quantity is offered for SS1H6LS?
The SS1H6LS is supplied in tape-and-reel format with 10,000 units per reel, compatible with standard SMT pick-and-place equipment. The SOD-123HE package dimensions and lead finish (matte tin) meet J-STD-002 requirements, ensuring reliable solder joint formation. Moisture sensitivity level is rated at Level 1 per J-STD-020, eliminating pre-bake requirements prior to reflow.
