Product details
Overview
SS210LW from Taiwan Semiconductor is a 2 A, 100 V Schottky barrier surface-mount rectifier in SOD-123W package, featuring 0.85 V forward voltage at 2 A and 20 µA reverse leakage at rated VR, optimized for high-efficiency DC/DC converters and switching power supplies.
For engineers reviewing the SS210LW datasheet, SS210LW pinout, SS210LW application, or SS210LW equivalent, key selection criteria include its 100 V repetitive peak reverse voltage, 50 A surge rating, 150 °C junction temperature limit, low thermal resistance (25 °C/W junction-to-lead), and RoHS/halogen-free compliance for industrial and adapter designs.
Technical Context
The SS210LW implements a single-die Schottky junction with guard ring over-voltage protection, enabling stable operation under transient stress. Its SOD-123W package supports automated placement and meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity requirements.
Thermal performance is defined by RθJL = 25 °C/W and RθJA = 80 °C/W, allowing sustained 2 A conduction up to 150 °C junction temperature. Electrical behavior follows typical Schottky characteristics: low VF with moderate VR dependency and exponentially increasing IR near rated VRRM.

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-2EY10-M3/5BT | Same SOD-123W package, 100 V VRRM, but VF = 0.82 V @ 2 A and IR = 30 µA @ 100 V | Higher leakage may impact ultra-low-power standby modes | Prefer SS210LW where IR < 25 µA is required for Energy Star Tier 2 compliance |
| ON Semiconductor SB2100T3G | SOD-123 package (not SOD-123W), same 100 V/2 A rating, VF = 0.87 V, IR = 15 µA | 0.2 mm shorter body reduces thermal mass; slightly higher VF increases conduction loss | Select SS210LW when board-level thermal management relies on SOD-123W's larger pad area and lower RθJL |
Compared with VS-2EY10-M3/5BT and SB2100T3G, the SS210LW delivers the optimal balance of low leakage (20 µA), industry-leading thermal resistance (25 °C/W), and robust surge capability (50 A) for space-constrained, thermally demanding 100 V rectification tasks.

FAQ
What is the maximum junction temperature rating for SS210LW?
The SS210LW has a maximum junction temperature (TJ max) of +150 °C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet Version D2301. This rating allows continuous operation in enclosed industrial environments where ambient temperatures reach 85 °C and PCB copper area provides adequate heat spreading. Derating curves confirm usable current capacity down to 1.2 A at 125 °C ambient with standard FR-4 layout.
Does SS210LW have a halogen-free and RoHS-compliant construction?
Yes, the SS210LW is explicitly certified halogen-free and RoHS compliant per Taiwan Semiconductor documentation (Version D2301). The molding compound meets UL 94V-0 flammability rating, terminals use matte tin plating, and all materials comply with EU Directive 2011/65/EU Annex II substance restrictions. Full material declarations are available upon request for automotive or medical-grade traceability.
What is the forward voltage specification of SS210LW at 2 A and 25 °C?
The SS210LW exhibits a maximum forward voltage (VF) of 0.85 V at IF = 2 A and TJ = 25 °C, as specified in the Electrical Specifications table of the Taiwan Semiconductor datasheet (Version D2301). This value is measured under pulse conditions (PW = 0.3 ms) and represents worst-case conduction loss for thermal design margining in high-frequency switch-mode applications.
Is SS210LW suitable for use in high-surge applications like motor drives?
Yes, the SS210LW supports a peak forward surge current (IFSM) of 50 A for an 8.3 ms half-sine wave, making it suitable for inrush and fault-current handling in motor drive auxiliary supplies. Its guard ring structure enhances ruggedness against repetitive voltage transients, and the 150 °C TJ rating ensures reliability during intermittent overload conditions common in industrial control systems.
What package type does SS210LW use and what are its key mechanical features?
The SS210LW uses the SOD-123W surface-mount package per JEDEC DO-219AB, with dimensions 2.90 × 1.40 mm and 0.10 mm lead thickness. Key features include cathode band polarity marking, matte tin-plated leads compliant with J-STD-002, JESD201 Class 2 whisker resistance, and J-STD-020 Level 1 moisture sensitivity-enabling direct placement without baking.
