Product details
Overview
SS220FSH from Taiwan Semiconductor is a 2 A, 200 V Schottky barrier surface-mount rectifier in SOD-128 package, optimized for high-efficiency DC/DC conversion with low forward voltage (0.84 V at 2 A, 25°C) and low junction capacitance (39 pF). It delivers high surge current capability (145 A at 1 ms), operates up to 150°C junction temperature, and is AEC-Q101 qualified for automotive-grade reliability in on-board power supplies.
For engineers reviewing the SS220FSH datasheet, SS220FSH pinout, SS220FSH application, or SS220FSH equivalent, key selection criteria include its 200 V reverse voltage rating, thermal resistance (RθJL = 18 °C/W), moisture sensitivity level 1 compliance, RoHS/halogen-free status, and suitability for space-constrained, high-frequency switching topologies requiring low conduction loss.
Technical Context
The SS220FSH implements a single-die Schottky structure with platinum-silicide or similar barrier metallization, enabling fast recovery (no stored charge) and minimal reverse recovery loss. Its 200 V VRRM rating targets mid-voltage industrial and automotive DC/DC stages where higher blocking voltage is required without sacrificing forward performance.
Thermal design relies on direct lead-to-PCB conduction via the SOD-128's exposed cathode pad; RθJL = 18 °C/W and RθJA = 75 °C/W are measured on a 5 mm × 5 mm Cu pad, confirming suitability for thermally demanding layouts without heatsinks at ≤2 A continuous operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage; defines safe operating range in buck, flyback, or OR-ing applications up to 200 V bus. |
| IF | 2 A - Continuous forward current rating; supports stable 2 A DC output in compact SMPS designs. |
| IFSM (t = 1 ms) | 145 A - Peak non-repetitive surge current; withstands inrush and fault transients in automotive load-dump scenarios. |

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-M3/5BT | Same SOD-128 package, 2 A/200 V rating, but VF = 0.87 V (max) at 2 A, 25°C - 30 mV higher typical drop. | Higher forward loss reduces efficiency in thermally constrained USB-C adapters. | Prefer SS220FSH where <0.85 V VF is critical for thermal budget. |
| ON Semiconductor SB220-E3/54 | SOD-128, 2 A/200 V, but not AEC-Q101 qualified; RθJA = 85 °C/W - 10 °C/W higher than SS220FSH. | Lacks automotive qualification and has reduced thermal performance in high-ambient environments. | Select SS220FSH for automotive or high-reliability industrial use; SB220-E3/54 acceptable for cost-sensitive consumer SMPS. |
Compared with VS-2EY20-M3/5BT and SB220-E3/54, the SS220FSH offers the lowest forward voltage among 200 V SOD-128 Schottkys and the only AEC-Q101-qualified option with RθJL ≤ 18 °C/W - making it optimal for automotive DC/DC and thermally aggressive industrial converters.

FAQ
What is the maximum junction temperature rating for the SS220FSH?
The SS220FSH has a maximum junction temperature (TJ) of +150 °C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating allows reliable operation in under-hood automotive environments and enclosed industrial enclosures. Derating curves confirm usable current capacity down to 1.2 A at 125 °C ambient when mounted on a 5 mm × 5 mm Cu pad. The SS220FSH must not exceed this limit to maintain long-term reliability and AEC-Q101 qualification integrity.
Is the SS220FSH pin-compatible with other parts in the SS2xFSH family?
Yes - all SS2xFSH variants (SS24FSH through SS220FSH) share identical SOD-128 packaging, pinout, and mechanical footprint. The anode and cathode terminals are physically and electrically consistent across the family, enabling board-level voltage scalability without layout changes. However, electrical parameters such as VF, IR, and CJ vary significantly by voltage grade, so system validation is required when substituting the SS220FSH for lower-voltage members like SS210FSH or SS215FSH.
Does the SS220FSH require special handling during reflow soldering?
No - the SS220FSH is rated at moisture sensitivity level (MSL) 1 per J-STD-020, meaning it has unlimited floor life and does not require dry-packaging or baking prior to reflow. Standard Pb-free reflow profiles (peak 260 °C, 20–40 s above 217 °C) are fully supported. Its matte tin-plated leads ensure reliable wetting, and the UL 94V-0 molding compound withstands thermal cycling without delamination. These attributes simplify manufacturing for high-volume SS220FSH deployment.
What is the reverse leakage current specification for the SS220FSH at elevated temperature?
At rated 200 V reverse voltage and TJ = 125 °C, the SS220FSH exhibits a maximum reverse leakage current (IR) of 5 mA, as specified in the Electrical Specifications table. At 25 °C, IR is limited to 10 µA. This low high-temperature leakage preserves efficiency in warm environments and prevents excessive standby loss in always-on automotive modules. The SS220FSH's leakage performance is superior to lower-voltage SS2xFSH variants at matching temperatures due to optimized barrier height design.
Can the SS220FSH be used in place of a silicon PN rectifier in an existing design?
Yes - the SS220FSH can directly replace silicon PN rectifiers rated for ≤200 V and ≤2 A, provided layout accommodates its SOD-128 footprint and thermal pad requirements. Key advantages include zero reverse recovery charge (eliminating switching spikes), lower VF (reducing conduction loss by ~300 mV), and faster turn-off. However, designers must verify that the lower leakage at high temperature and absence of reverse recovery do not destabilize snubber networks or control-loop compensation originally tuned for silicon diodes. The SS220FSH is especially effective in high-frequency (>300 kHz) topologies where silicon diode losses dominate.
