Product details
Overview
SS210ALH from Taiwan Semiconductor is a 2 A, 100 V Schottky barrier surface-mount rectifier in Thin SMA package, featuring low forward voltage (0.76 V max at 2 A, 25°C), high surge capability (50 A IFSM), AEC-Q101 qualification, and junction temperature rating up to +150°C. It serves as an output rectifier in automotive-grade DC/DC converters and industrial SMPS.
For engineers reviewing the SS210ALH datasheet, SS210ALH pinout, SS210ALH application, or SS210ALH equivalent, key selection criteria include reverse voltage margin (100 V VRRM), thermal resistance (RθJL = 21 °C/W), moisture sensitivity level (MSL 1), and RoHS/halogen-free compliance for high-reliability power conversion designs.
Technical Context
The SS210ALH uses a single-die Schottky structure optimized for low conduction loss and fast switching in continuous forward-biased operation. Its 100 V peak reverse voltage supports 48 V–60 V bus-derived DC/DC stages while maintaining <0.85 V forward drop at full rated current and 25°C.
Thermal performance is defined for PCB mounting on 5 mm × 5 mm copper pads, with RθJA = 78 °C/W and RθJC = 20 °C/W. Reverse leakage remains ≤10 µA at 25°C and ≤5 mA at 125°C, enabling stable operation in thermally constrained automotive under-hood environments.

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 | Same 100 V VRRM, 2 A IF, but SMA package (not Thin SMA); RθJA = 85 °C/W vs. 78 °C/W | Slightly higher thermal resistance may require larger copper area for equivalent junction temperature | Preferred where standard SMA footprint compatibility is required over ultra-thin profile |
| ON Semiconductor SB2100 | 100 V VRRM, 2 A IF, but VF = 0.85 V max @ 2 A - 0.09 V higher than SS210ALH | Higher conduction loss increases thermal load in sealed or high-ambient environments | Selected when legacy SMA-2 footprint reuse is mandatory and efficiency margin is acceptable |
Compared with VS-2EY10-M3 and SB2100, the SS210ALH delivers lower forward voltage and superior thermal resistance in a thinner package, making it optimal for space- and thermally constrained automotive and industrial DC/DC modules where board height and thermal headroom are critical.

FAQ
What is the maximum junction temperature rating for SS210ALH?
The SS210ALH has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table. This allows the device to operate reliably in under-hood automotive environments or sealed industrial enclosures where ambient temperatures reach +105°C. Derating curves confirm usable current capacity down to 1.2 A at 125°C case temperature. The SS210ALH must be mounted on a PCB with adequate copper area to maintain TJ within limit under full load.
Is SS210ALH compatible with lead-free reflow processes?
Yes, the SS210ALH features matte tin-plated leads compliant with J-STD-002 solderability standards and is qualified for standard lead-free reflow profiles (peak temperature up to 260°C). Its MSL Level 1 rating means no dry-pack or pre-bake is required before assembly. The Thin SMA package maintains mechanical integrity across multiple reflow cycles, and the UL 94V-0 molding compound resists thermal degradation during soldering. SS210ALH is fully compatible with IPC-J-STD-020-compliant manufacturing.
How does the forward voltage of SS210ALH compare at elevated temperature?
At 2 A and 125°C, the SS210ALH exhibits a maximum forward voltage of 0.76 V - lower than its 25°C value of 0.85 V - due to the negative temperature coefficient of Schottky diodes. This behavior improves system efficiency at high operating temperatures. Measured typ values show 0.62 V at 2 A and 125°C, confirming stable conduction loss under thermal stress. The SS210ALH datasheet specifies this performance across the full -55°C to +150°C junction range.
What is the reverse leakage current of SS210ALH at 125°C?
The SS210ALH exhibits a maximum reverse leakage current (IR) of 5 mA at rated VRRM = 100 V and TJ = 125°C, as specified in the electrical characteristics table. At 25°C, leakage is limited to 10 µA - three orders of magnitude lower. This low high-temperature leakage ensures minimal standby power loss in always-on automotive modules and contributes to predictable thermal behavior in high-density power designs using SS210ALH.
Does SS210ALH have automotive qualification documentation available?
Yes, the SS210ALH is explicitly AEC-Q101 qualified, as stated in the features section and confirmed in the product summary. Taiwan Semiconductor provides full AEC-Q101 test reports covering HTOL, temperature cycling, HAST, and mechanical shock. Qualification applies to the exact SS210ALH part number in Thin SMA packaging. Customers can request the AEC-Q101 certificate and test summary directly from TSC or via Aetrix Electronics' technical support for SS210ALH design-in validation.
