Product details
Overview
SK210AH from Taiwan Semiconductor is a 2A, 100V Schottky barrier rectifier in DO-214AC (SMA) package, designed for high-frequency DC/DC conversion and reverse battery protection. It delivers 0.85V forward voltage at 2A and 25°C, supports 50A non-repetitive surge current, and operates up to 150°C junction temperature.
For engineers reviewing the SK210AH datasheet, SK210AH pinout, SK210AH application, or SK210AH equivalent, key selection criteria include its 100V VRRM, low 0.85V VF at rated current, AEC-Q101 qualification, moisture sensitivity level 1 rating, and DO-214AC surface-mount compatibility for automotive and industrial power systems.
Technical Context
The SK210AH employs a single-die Schottky structure optimized for low conduction loss and fast switching in low-voltage, high-frequency power supplies. Its guard ring design enhances over-voltage robustness, while the matte tin-plated leads ensure reliable solderability per J-STD-002.
With a junction-to-ambient thermal resistance of 88°C/W and rated for operation from –55°C to +150°C, the SK210AH maintains stable performance under transient thermal loads and meets JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; defines safe operating range in 12–48V automotive and industrial bus applications. |
| IF | 2 A - Continuous forward current rating; supports sustained power delivery in compact DC/DC converters without derating below 100°C. |
| VF @ 2A, 25°C | 0.85 V - Low forward drop reduces conduction loss and improves system efficiency by ~1.7W vs. silicon diodes at 2A. |
| IR @ 100V, 25°C | 0.1 mA - Ultra-low reverse leakage minimizes standby power loss in battery-critical systems like car lighting and ECU modules. |
| IFSM | 50 A - Peak surge capability withstands 8.3ms half-sine transients, enabling robust freewheeling in motor drive and load dump scenarios. |
| TJ max | +150 °C - Extended junction temperature rating allows operation in under-hood environments without forced cooling. |
| RθJA | 88 °C/W - Thermal resistance enables PCB-level heatsinking with standard copper pour; no external heatsink required at ≤1W dissipation. |
Pinout & Package
Package: DO-214AC (SMA), surface-mount plastic case with cathode band polarity indicator, 0.070g weight, UL 94V-0 molding compound, and JESD201 Class 2 whisker-resistant matte tin leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to lower-potential side (e.g., ground or switch node); requires adequate copper area for thermal management. |
| Cathode | Current exit point during forward conduction; marked by band | Connected to higher-potential rail (e.g., input bus or inductor output); band orientation must align with PCB silkscreen. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing-enables use in engine control and ADAS subsystems. |
| Guard ring structure | Improves edge termination robustness against localized over-voltage stress, increasing long-term reliability in noisy 12V/24V vehicle electrical systems. |
| Moisture sensitivity level 1 | No floor life limitation or baking requirement before reflow; simplifies SMT line integration and reduces manufacturing overhead. |
| Halogen-free & RoHS compliant | Meets EU Directive 2011/65/EU and IEC 61249-2-21; supports green manufacturing and end-of-life recycling compliance. |

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 100V VRRM, 2A IF, but 0.82V VF at 2A and 25°C; slightly lower IR (0.05mA @ 100V, 25°C). | Identical DO-214AC package; validated for industrial power supplies but not AEC-Q101 qualified. | Select when automotive qualification is unnecessary and sub-30mV VF reduction justifies sourcing from alternate vendor. |
| ON Semiconductor SB2100-E3/54 | 100V VRRM, 2A IF, 0.88V VF @ 2A/25°C; 0.2mA IR @ 100V/25°C; same 150°C TJ max. | DO-214AC package; AEC-Q101 qualified but with higher VF and leakage than SK210AH. | Choose when dual-sourcing across Taiwan Semiconductor and ON Semi is required for BOM resilience, accepting minor efficiency trade-off. |
Compared with VS-2EY10-M3/5BT and SB2100-E3/54, the SK210AH offers the best balance of AEC-Q101 compliance, 0.85V forward voltage, and 0.1mA reverse leakage-making it optimal for thermally constrained automotive modules where both reliability and efficiency are critical.

FAQ
What is the maximum junction temperature rating for the SK210AH?
The SK210AH has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet Version C2307. This enables operation in under-hood automotive environments and high-ambient industrial enclosures without thermal derating below 125°C ambient. The SK210AH maintains specified electrical performance up to this limit when mounted on a standard 1-inch² 2-oz copper pad.
Is the SK210AH AEC-Q101 qualified?
Yes, the SK210AH is explicitly AEC-Q101 qualified, as confirmed in the FEATURES section of the Taiwan Semiconductor datasheet Version C2307. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and electrostatic discharge (ESD), making the SK210AH suitable for automotive powertrain, body electronics, and ADAS applications where component reliability is mission-critical.
What is the forward voltage of the SK210AH at 2A and 25°C?
The forward voltage (VF) of the SK210AH is 0.85 V at 2A forward current and 25°C junction temperature, per the ELECTRICAL SPECIFICATIONS table in the Taiwan Semiconductor datasheet Version C2307. This value is measured under pulse test conditions (PW = 0.3ms), ensuring repeatability and minimizing self-heating effects during characterization. The SK210AH maintains this low VF across its full operating temperature range.
Does the SK210AH have a moisture sensitivity level (MSL) rating?
Yes, the SK210AH carries a moisture sensitivity level (MSL) rating of Level 1 per J-STD-020, as stated in the FEATURES section of the Taiwan Semiconductor datasheet Version C2307. This means the device has unlimited floor life and does not require dry pack storage or baking prior to reflow soldering-simplifying handling and reducing manufacturing risk in high-volume SMT assembly lines.
What package type does the SK210AH use?
The SK210AH uses the DO-214AC (SMA) surface-mount package, confirmed in the MECHANICAL DATA and ORDERING INFORMATION sections of the Taiwan Semiconductor datasheet Version C2307. It features a molded plastic body meeting UL 94V-0 flammability rating, matte tin-plated leads compliant with J-STD-002, and a cathode band for polarity identification. The SK210AH's footprint matches JEDEC DO-214AC standard dimensions.
