Product details
Overview
SK210AHR3G from Taiwan Semiconductor is a 2 A, 100 V Schottky barrier surface-mount rectifier in DO-214AC (SMA) package, qualified to AEC-Q101, with VF = 0.85 V at 2 A and TJ = 25°C, IR = 0.1 mA at VR = 100 V and TJ = 25°C, and IFSM = 50 A. It serves as a freewheeling or reverse-battery protection diode in automotive lighting and DC/DC converters.
For engineers reviewing the SK210AHR3G datasheet, SK210AHR3G pinout, SK210AHR3G application, or SK210AHR3G equivalent, key selection criteria include its 100 V VRRM rating, low 0.85 V forward voltage at rated current, AEC-Q101 qualification for automotive use, moisture sensitivity level 1 compliance, and DO-214AC thermal performance (RθJA = 88°C/W).
Technical Context
This Schottky rectifier uses a single-die construction with guard ring over-voltage protection and matte tin-plated leads solderable per J-STD-002. Its junction temperature range spans –55°C to +150°C, supporting operation in under-hood automotive environments.
The device exhibits dV/dt capability of 10,000 V/µs and non-repetitive avalanche energy ERSM = 20 mJ (L = 40 mH), enabling robust switching transient handling in high-frequency power conversion topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; defines safe operating reverse bias in battery protection or flyback clamp circuits. |
| IF | 2 A - Continuous forward current rating; supports sustained conduction in 12 V/24 V automotive DC/DC stages. |
| VF @ 2 A, 25°C | 0.85 V - Low forward drop reduces conduction loss and improves system efficiency vs. standard PN diodes. |
| IR @ 100 V, 25°C | 0.1 mA - Low leakage enables stable reverse blocking in low-power standby modes. |
| IFSM | 50 A - Peak surge current tolerance allows survival during load dump or cold-crank transients. |
| RθJA | 88 °C/W - Thermal resistance from junction to ambient; determines heatsinking requirements in sealed enclosures. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in high-ambient under-hood locations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS210H from Diodes Inc. | VRRM = 100 V, VF = 0.85 V @ 2 A, RθJA = 90°C/W, AEC-Q101 qualified, same DO-214AC package. | Identical automotive-grade performance; slightly higher thermal resistance limits power density in compact layouts. | Drop-in alternative where board space and qualification match; verify layout thermal relief matches SS210H's pad recommendations. |
| SB210 from ON Semiconductor | VRRM = 100 V, VF = 0.87 V @ 2 A, IFSM = 50 A, RθJA = 85°C/W, AEC-Q101 qualified, DO-214AC package. | Marginally higher VF increases conduction loss; lower RθJA improves thermal headroom in high-ambient designs. | Preferred when thermal margin is constrained; confirm cathode marking alignment matches SK210AHR3G footprint. |
Compared with SK210AHR3G, SS210H offers identical electrical specs but slightly reduced thermal performance, while SB210 trades 0.02 V higher VF for better junction-to-ambient cooling-making SB210 suitable for thermally dense automotive modules and SS210H ideal for cost-optimized, space-constrained lighting drivers.

FAQ
What is the maximum junction temperature rating for SK210AHR3G?
The SK210AHR3G has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating enables reliable operation in high-ambient automotive environments such as engine compartments. The SK210AHR3G must be mounted on appropriate copper area to maintain junction temperature within this limit under full load.
Is SK210AHR3G suitable for reverse-battery protection in 24 V commercial vehicles?
Yes, SK210AHR3G is suitable for reverse-battery protection in 24 V commercial vehicles. Its 100 V VRRM rating provides sufficient margin above typical 24 V system transients (up to ±36 V), and its AEC-Q101 qualification confirms automotive-grade reliability. The SK210AHR3G's 0.1 mA reverse leakage at 100 V and 25°C ensures minimal standby power loss in always-on modules.
Does SK210AHR3G have moisture sensitivity level (MSL) restrictions for reflow assembly?
No, SK210AHR3G has moisture sensitivity level 1 per J-STD-020, meaning it may be stored indefinitely at ambient conditions without baking prior to reflow soldering. This eliminates pre-assembly bake steps and reduces process complexity in high-volume automotive manufacturing. The SK210AHR3G's MSL-1 rating is confirmed in the mechanical data section of the official datasheet.
What is the forward voltage of SK210AHR3G at 2 A and 100°C junction temperature?
The forward voltage of SK210AHR3G at 2 A and 100°C junction temperature is not explicitly specified in the published datasheet; only VF = 0.85 V is guaranteed at 2 A and 25°C. However, typical forward voltage curves (Fig.10–Fig.12) show VF increases to approximately 0.75–0.78 V at 100°C for SK29–SK210AH variants. Designers should apply derating and verify with actual thermal modeling for the SK210AHR3G in their specific layout.
How does the guard ring feature in SK210AHR3G improve circuit robustness?
The guard ring in SK210AHR3G enhances over-voltage ruggedness by controlling electric field distribution at the die edge, preventing premature avalanche breakdown during transient surges. This design allows the SK210AHR3G to withstand 10,000 V/µs dV/dt and 20 mJ non-repetitive avalanche energy (L = 40 mH), reducing need for external clamping components in DC/DC converter flyback paths.
