Product details
Overview
SS16LW from Taiwan Semiconductor is a 1A, 60V Schottky barrier surface-mount rectifier in SOD-123W package, featuring 0.70V forward voltage at 1A and 30A surge current capability. It operates up to +150°C junction temperature and delivers low power loss for high-efficiency DC/DC conversion in compact power supplies.
For engineers reviewing the SS16LW datasheet, SS16LW pinout, SS16LW application, or SS16LW equivalent, key selection criteria include its 60V VRRM, 0.70V VF at 1A, 30A IFSM, thermal resistance of 25°C/W (junction-to-lead), and SOD-123W footprint compatibility with automated placement.
Technical Context
The SS16LW implements a single-die Schottky barrier structure optimized for low forward voltage and fast switching in unidirectional rectification. Its guard ring design provides overvoltage protection, while matte tin-plated leads ensure solderability per J-STD-002.
Rated for operation from –55°C to +150°C, it achieves 100µA maximum reverse leakage at rated VR and 25°C, with junction-to-lead thermal resistance of 25°C/W enabling reliable thermal dissipation in space-constrained layouts.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS16HE3/5BT | Same 1A/60V rating but TO-277 package; RθJA = 75°C/W vs. SS16LW's 80°C/W. | Requires larger board area; unsuitable for ultra-thin adapters where SOD-123W height <1.1mm is critical. | Select SS16HE3/5BT only when higher thermal mass or alternate mounting method is needed. |
| SB160-TB | 1A/60V, but VF = 0.75V at 1A; SOD-123 package (not SOD-123W); no guard ring. | Lacks overvoltage ruggedness; may require external clamping in noisy industrial environments. | Choose SB160-TB only if cost is primary constraint and system-level transients are well-controlled. |
Compared with SS16HE3/5BT and SB160-TB, the SS16LW uniquely combines SOD-123W's low-profile footprint, guard ring protection, and 0.70V VF-making it optimal for space-limited, high-reliability 60V rectification where thermal and surge margins must coexist.

FAQ
What is the maximum junction temperature rating for the SS16LW?
The SS16LW has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet. This allows sustained operation in thermally constrained enclosures such as slim TV power boards or sealed industrial DC/DC modules. Derating begins above this limit, and the device must not exceed +150°C under any steady-state or transient condition. The SS16LW maintains specified electrical performance within this range.
Does the SS16LW have a guard ring, and what function does it serve?
Yes, the SS16LW incorporates a guard ring structure explicitly cited in its features list. This design element enhances edge termination robustness, improving resistance to voltage-induced avalanche breakdown during transient overvoltage events-such as line surges or inductive kickback. It eliminates the need for external snubber networks in many 60V-class SMPS designs, directly contributing to bill-of-materials reduction and improved long-term reliability of the SS16LW in real-world applications.
What is the forward voltage specification of the SS16LW at 1A and 25°C?
The SS16LW has a maximum forward voltage (VF) of 0.70 V at 1A and 25°C, as confirmed in the Electrical Specifications table of the Taiwan Semiconductor datasheet. This value is measured under pulsed conditions (PW = 0.3ms) to minimize self-heating effects. At elevated temperatures (e.g., 125°C), VF decreases slightly due to Schottky diode physics, but the 0.70V spec remains the design reference for worst-case conduction loss calculation in the SS16LW.
Is the SS16LW compatible with lead-free reflow soldering processes?
Yes, the SS16LW uses matte tin-plated leads that are fully solderable per J-STD-002 and rated for standard lead-free reflow profiles (peak temperature ≤ 260°C). Its moisture sensitivity level is rated at MSL-1 per J-STD-020, meaning it can be stored indefinitely at ambient conditions without baking prior to assembly. This makes the SS16LW compatible with high-volume automated SMT lines without special handling, ensuring consistent manufacturability of the SS16LW across production runs.
What packaging format is used for the SS16LW, and how many units are supplied per reel?
The SS16LW is supplied in tape-and-reel packaging per the Ordering Information section: 10,000 units per reel. The physical package is SOD-123W, a compact surface-mount outline with standardized sprocket holes and cover tape. This format supports high-speed pick-and-place machines and ensures consistent feeding accuracy. The SS16LW reel meets EIA-481 standards, and the part marking "16LW" is laser-etched on the cathode end for automated optical inspection compatibility.
