Product details
Overview
SS16LSH from Taiwan Semiconductor is a 1A, 60V Schottky barrier surface-mount rectifier in SOD-123HE package, featuring 0.70V forward voltage at 1.0A/25°C, 48pF junction capacitance at 1MHz/4V, and 30A peak surge current capability. It serves as a low-loss freewheeling or reverse-battery protection diode in automotive lighting and DC/DC converters.
For engineers reviewing the SS16LSH datasheet, SS16LSH pinout, SS16LSH application, or SS16LSH equivalent, key selection criteria include its AEC-Q101 qualification, 0.85mm profile, moisture sensitivity level 1, and thermal resistance (RθJA = 70°C/W), critical for high-density automotive and industrial power designs.
Technical Context
The SS16LSH uses a single-die Schottky structure optimized for low forward voltage and fast switching, with no minority-carrier storage delay. Its 60V VRRM rating and 0.58V typical VF at 0.5A/25°C enable efficient operation in 12V–48V automotive subsystems.
Thermally, it supports continuous operation up to +150°C junction temperature and delivers 30A non-repetitive surge current under 8.3ms half-sine conditions. The SOD-123HE package provides UL 94V-0 flammability compliance and matte tin-plated leads per J-STD-002 solderability standards.

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-M3/45 | Same 60V VRRM, 1A IF, but SOD-123FL package (0.95mm height); VF = 0.72V max @ 1A | Higher profile may limit use in ultra-low-height assemblies; identical AEC-Q101 qualification | Prefer SS16LSH where board clearance <0.85mm is required |
| ON Semiconductor SB160T3G | 60V VRRM, 1A IF, SOD-123 package (1.0mm height); VF = 0.75V max @ 1A; not AEC-Q101 qualified | Lacks automotive qualification; suitable only for commercial/industrial environments | Choose SS16LSH for automotive or extended-temperature deployments requiring validated reliability |
Compared with VS-1EQH06-M3/45 and SB160T3G, the SS16LSH offers the lowest profile (0.85mm), tightest VF spec (0.70V max), and full AEC-Q101 compliance-making it the optimal choice for space-constrained, automotive-grade 60V Schottky rectification.

FAQ
What is the maximum junction temperature rating for the SS16LSH?
The SS16LSH has a maximum junction temperature (TJ) rating of +150°C, verified per the manufacturer's absolute maximum ratings table. This allows uninterrupted operation in under-hood automotive environments and sealed industrial enclosures. The SS16LSH maintains full 1A current capability up to this temperature when thermal design accounts for its 70°C/W junction-to-ambient resistance.
Is the SS16LSH suitable for reverse battery protection in 24V systems?
Yes, the SS16LSH is well-suited for reverse battery protection in 24V systems due to its 60V VRRM, 1A continuous forward current, and 30A peak surge rating. Its 0.70V forward voltage at 1A minimizes power loss during normal operation, and AEC-Q101 qualification ensures robustness against automotive transients like load dump and jump-start events. The SS16LSH is routinely deployed in telematics and ADAS power inputs.
Does the SS16LSH require moisture preconditioning before reflow soldering?
No, the SS16LSH has a moisture sensitivity level (MSL) of 1 per J-STD-020, meaning it can be stored indefinitely at ≤30°C/60% RH and placed directly into reflow without baking or dry-pack requirements. This simplifies manufacturing logistics and eliminates risk of popcorning during lead-free reflow profiles. The SS16LSH's MSL-1 rating is confirmed in the mechanical data section of its official datasheet.
What is the typical junction capacitance of the SS16LSH and why does it matter?
The SS16LSH exhibits a typical junction capacitance (CJ) of 48 pF at 1 MHz and 4.0 V reverse bias. This low value reduces displacement current and switching losses in high-frequency DC/DC converters (>300 kHz), improving efficiency and easing EMI filter design. In buck converter freewheeling applications, the SS16LSH's 48 pF CJ helps minimize ringing and voltage overshoot compared to higher-capacitance alternatives.
How does the forward voltage of the SS16LSH compare to other 60V Schottky rectifiers in the same family?
At 1.0 A and 25°C, the SS16LSH has a maximum forward voltage of 0.70 V-lower than the SS110LSH (0.80 V) and SS115LSH (0.90 V) but higher than the SS14LSH (0.55 V). This reflects the trade-off between reverse voltage rating and VF: among 60V-rated variants, the SS16LSH delivers the best balance of low conduction loss and sufficient margin for 48V nominal systems. Its VF performance is confirmed in the electrical specifications table of the SS12LSH–SS115LSH datasheet.
