Product details
Overview
SS16LH from Taiwan Semiconductor is a 1 A, 60 V Schottky barrier surface-mount rectifier in Sub SMA package, featuring low forward voltage (0.580 V at 0.5 A, 25°C), high surge current capability (30 A), and AEC-Q101 qualification for automotive use in reverse battery protection and DC/DC converters.
For engineers reviewing the SS16LH datasheet, SS16LH pinout, SS16LH application, or SS16LH equivalent, key selection criteria include its 60 V repetitive peak reverse voltage, 125°C max junction temperature, guard ring–enhanced overvoltage protection, and moisture sensitivity level 1 compliance for reliable SMT assembly.
Technical Context
The SS16LH operates as a single-die Schottky rectifier with unidirectional conduction, optimized for low-loss power conversion in high-frequency switching topologies. Its 45°C/W junction-to-lead thermal resistance and 100°C/W junction-to-ambient rating support thermally constrained PCB layouts.
It delivers 0.700 V max forward voltage at 1.0 A and 25°C, with reverse leakage limited to 400 µA at 60 V and 25°C, enabling efficient freewheeling and clamping in automotive lighting and inverter circuits where fast recovery and minimal conduction loss are critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB160-E3/52 | 60 V VRRM, 1 A IF, SMA package, VF = 0.75 V max at 1 A - higher forward drop than SS16LH | Less suitable for thermally constrained 12 V systems due to +150 mV VF penalty | Prefer SS16LH where board space and thermal margin are limited |
| SS16HE3_A/H | 60 V VRRM, 1 A IF, SMA package, AEC-Q101 qualified, VF = 0.65 V max at 1 A - wider VF distribution | Acceptable for non-critical automotive modules but lacks SS16LH's tighter VF spec | SS16LH offers better consistency in low-VF-sensitive designs like LED drivers |
Compared with SB160-E3/52 and SS16HE3_A/H, the SS16LH provides the lowest guaranteed forward voltage (0.580 V at 0.5 A) and superior thermal resistance (45°C/W), making it optimal for space-constrained, high-efficiency automotive power rails requiring long-term reliability under thermal cycling.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the SS16LH?
The SS16LH has a VRRM rating of 60 V, meaning it can reliably block up to 60 V of reverse voltage in continuous operation. This value is confirmed in the Absolute Maximum Ratings table of the official TSC datasheet (Version A2103), and aligns with the "16" in the part number denoting 60 V (SS1xLH → x=6 → 60 V). Exceeding this voltage risks avalanche breakdown.
Is the SS16LH suitable for automotive applications?
Yes, the SS16LH is AEC-Q101 qualified and explicitly designed for automotive use. It meets stress tests including high-temperature reverse bias, temperature cycling, and mechanical shock. Its 125°C max junction temperature, guard ring structure, and moisture sensitivity level 1 make it appropriate for under-hood and body-control module applications where reliability under thermal and environmental stress is critical.
What is the forward voltage (VF) specification for SS16LH at 1 A and 25°C?
The SS16LH has a maximum forward voltage of 0.700 V at 1 A and 25°C, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and reflects worst-case conduction loss. At 0.5 A and 25°C, VF is capped at 0.580 V - a key differentiator for efficiency-sensitive designs like LED drivers and low-drop power rails.
Does the SS16LH have a defined polarity marking, and how is it identified?
Yes, the SS16LH uses a cathode band to indicate polarity - a visible stripe near one end of the Sub SMA package. Per the Mechanical Data section, this band identifies the cathode terminal, which must be connected toward the higher-potential side (e.g., battery positive) in reverse-battery protection configurations. The anode is the unmarked end, and correct orientation is essential to ensure proper blocking function.
What packaging and reel quantity is offered for SS16LH?
The SS16LH is supplied in Sub SMA package on tape-and-reel format, with 10,000 units per reel, as stated in the Ordering Information section of the TSC datasheet. This standard packaging supports high-speed automated placement and is compatible with industry-standard pick-and-place equipment used in automotive electronics manufacturing.
