Product details
Overview
SS220LWH from Taiwan Semiconductor is a 2 A, 200 V Schottky barrier surface-mount rectifier in SOD-123W package, featuring 0.95 V forward voltage at 2 A and 10 µA reverse leakage at rated VR, qualified to AEC-Q101 for automotive-grade reliability, and used in reverse battery protection and DC/DC converters.
For engineers reviewing the SS220LWH datasheet, SS220LWH pinout, SS220LWH application, or SS220LWH equivalent, key selection factors include its 200 V repetitive peak reverse voltage, 50 A surge capability, 150 °C max junction temperature, guard ring over-voltage protection, and SOD-123W thermal performance (RθJA = 80 °C/W).
Technical Context
The SS220LWH implements a single-die Schottky barrier structure optimized for low forward voltage drop and fast switching in high-frequency power conversion. Its 200 V VRRM rating enables use in higher-voltage automotive and industrial DC/DC topologies where lower-voltage variants (e.g., SS24LWH) are insufficient.
Thermally, it delivers RθJL = 25 °C/W and RθJA = 80 °C/W in the SOD-123W package, supporting continuous 2 A operation up to 125 °C ambient with appropriate PCB copper area. The cathode band polarity marking and matte tin-plated leads ensure compatibility with J-STD-002 soldering and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - supports input rails up to 140 V DC in automotive systems with safety margin |
| IF | 2 A continuous - sustains steady-state load current without derating below 125 °C ambient |
| VF @ 2 A | 0.95 V max - reduces conduction loss to ≤1.9 W per device at full load |
| IR @ VR | 10 µA max - ensures minimal leakage in reverse-battery protection circuits |
| IFSM | 50 A - withstands 8.3 ms half-sine surge events common in load dump transients |
| TJ max | 150 °C - enables operation in under-hood environments with elevated ambient temperatures |
| RθJA | 80 °C/W - requires ≥25 mm² of 1 oz copper pad for thermal compliance at full current |

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-2EY20-M3/57T | 2 A, 200 V, VF = 0.85 V typ at 2 A; SOD-123 package (not SOD-123W); RθJA = 100 °C/W | Higher thermal resistance limits continuous current in compact layouts; no AEC-Q101 qualification | Select when cost sensitivity outweighs automotive qualification or thermal constraints |
| ON Semiconductor SB220 | 2 A, 200 V, VF = 0.92 V max at 2 A; SMC (DO-214AB) package; IFSM = 60 A | Larger footprint (6.2 × 4.6 mm) but superior surge handling; not AEC-Q101 qualified | Select when board space permits larger package and higher surge margin is prioritized over qualification |
Compared with VS-2EY20-M3/57T and SB220, the SS220LWH uniquely combines AEC-Q101 qualification, SOD-123W's compact thermal profile (RθJA = 80 °C/W), and automotive-compliant moisture sensitivity-making it the only option qualified for under-hood deployment in space-constrained modules.

FAQ
What is the maximum junction temperature rating for the SS220LWH?
The SS220LWH has a maximum junction temperature (TJ) of +150 °C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet revision B2301. This allows operation in under-hood automotive environments where ambient temperatures reach 125 °C, provided thermal design meets RθJA = 80 °C/W with adequate PCB copper. The SS220LWH must not exceed this limit to maintain reliability and AEC-Q101 compliance.
Is the SS220LWH pin-compatible with other parts in the SS2xLWH series?
Yes, all SS2xLWH parts-including SS24LWH, SS26LWH, SS210LWH, SS215LWH, and SS220LWH-share identical SOD-123W package dimensions, pinout, and terminal configuration. The only differences are VRRM (40–200 V) and corresponding forward/reverse electrical parameters. This allows voltage-scaling design reuse without layout changes, as confirmed in the "MECHANICAL DATA" and "ABSOLUTE MAXIMUM RATINGS" sections of the SS220LWH datasheet.
Does the SS220LWH have AEC-Q101 qualification documentation available?
Yes, the SS220LWH is explicitly stated as AEC-Q101 qualified in the "FEATURES" section of Taiwan Semiconductor's official SS24LWH–SS220LWH datasheet (Version B2301). Full qualification test reports-including temperature cycling, humidity bias HAST, and ESD testing-are available upon request from TSC's automotive support team and referenced in the product's PPAP documentation package.
What is the forward voltage specification for SS220LWH at 2 A and 25 °C?
The SS220LWH has a maximum forward voltage (VF) of 0.95 V at IF = 2 A and TJ = 25 °C, as specified in the "ELECTRICAL SPECIFICATIONS" table of the B2301 datasheet. This value is measured under pulse conditions (PW = 0.3 ms) and represents worst-case conduction loss-critical for calculating thermal rise and efficiency in DC/DC converter outputs and reverse battery protection paths.
How is polarity indicated on the SS220LWH package?
Polarity on the SS220LWH is indicated by a cathode band printed on the molded plastic body, consistent with JEDEC DO-219 AB standards and shown in the "PACKAGE OUTLINE DIMENSIONS" diagram (Page 5, Version B2301). The banded end is the cathode terminal; the opposite end is the anode. This marking is visible under standard optical inspection and aligns with automated optical recognition (AOI) systems used in SMT assembly lines.
