Product details
Overview
SK215AH from Taiwan Semiconductor is a 2 A, 150 V Schottky barrier surface-mount rectifier in DO-214AC (SMA) package, featuring 0.95 V forward voltage at 2 A and 0.1 mA reverse current at rated VR, optimized for high-frequency DC/DC converters and reverse battery protection in automotive lighting systems.
For engineers reviewing the SK215AH datasheet, SK215AH pinout, SK215AH application, or SK215AH equivalent, key selection criteria include its AEC-Q101 qualification, 150 V repetitive peak reverse voltage, 50 A surge capability, 150 °C maximum junction temperature, and low VF/IR trade-off at high blocking voltage.
Technical Context
The SK215AH employs a single-die Schottky junction with guard ring structure for over-voltage robustness and meets JESD201 Class 2 whisker resistance. Its thermal design supports 150 °C continuous operation with RθJA = 88 °C/W in standard PCB layout.
Electrical behavior is characterized by low conduction loss (VF = 0.95 V @ 2 A, 25 °C) and tight leakage control (IR ≤ 0.1 mA @ 150 V, 25 °C), enabling efficient freewheeling and polarity protection in 12–48 V automotive subsystems.

| IF | 2 A - Continuous forward current rating; supports sustained load in compact DC/DC output stages |
| IFSM | 50 A - Non-repetitive surge current (8.3 ms); handles inrush and fault transients without failure |
| VF | 0.95 V @ 2 A, 25 °C - Low forward drop reduces conduction loss and thermal stress in high-duty-cycle apps |
| IR | 0.1 mA @ 150 V, 25 °C - Ultra-low leakage enables reliable reverse-battery protection in always-on modules |
| TJ max | 150 °C - Extended junction temperature rating allows operation in under-hood environments |
| RθJA | 88 °C/W - Thermal resistance enables 2 A operation on standard 1 oz copper without forced cooling |

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-2EY15-M3/54 | Same DO-214AC package; 2 A / 150 V; VF = 0.89 V @ 2 A but IR = 0.5 mA @ 150 V | Higher leakage may impact reverse-battery protection hold time in always-on modules | Prefer SK215AH where ultra-low IR is critical; choose VS-2EY15-M3/54 where lower VF dominates efficiency budget |
| ON Semiconductor SB2150-T | DO-214AA (SMB) package; 2 A / 150 V; VF = 0.93 V @ 2 A; IR = 0.2 mA @ 150 V; RθJA = 70 °C/W | Larger footprint and higher thermal resistance limit use in space-constrained layouts | Choose SB2150-T only if SMB pad compatibility exists; SK215AH offers superior thermal performance in SMA-limited designs |

FAQ
What is the maximum junction temperature rating for the SK215AH?
The SK215AH has a maximum junction temperature (TJ) rating of +150 °C, verified per absolute maximum ratings table in the official datasheet. This allows continuous operation in high-ambient environments such as under-hood automotive applications or enclosed industrial enclosures. The SK215AH maintains specified electrical parameters up to this temperature when derated per the forward current derating curve.
Is the SK215AH suitable for reverse battery protection in 24 V automotive systems?
Yes, the SK215AH is well-suited for reverse battery protection in 24 V systems due to its 150 V VRRM, 0.1 mA reverse current at rated voltage, and AEC-Q101 qualification. Its low leakage ensures minimal standby current draw, and the guard ring structure enhances robustness against load dump transients. The SK215AH is explicitly cited in TSC's application guidance for car lighting and reverse protection circuits.
Does the SK215AH have a halogen-free and RoHS-compliant construction?
Yes, the SK215AH uses halogen-free molding compound and complies with RoHS Directive 2011/65/EU, as confirmed in the "Features" section of the official datasheet. Lead finish is matte tin, solderable per J-STD-002, and moisture sensitivity level is rated at Level 1-eliminating bake requirements prior to reflow. These attributes are standardized across the SK2xAH series, including the SK215AH.
What is the forward voltage drop of the SK215AH at 2 A and 25 °C?
The forward voltage (VF) of the SK215AH is 0.95 V at 2 A and 25 °C, as specified in the Electrical Specifications table under "Forward voltage(1)" for the SK215AH row. This value is measured using a 0.3 ms pulse test and reflects typical conduction loss in DC/DC output stages. At elevated temperatures (e.g., 125 °C), VF decreases slightly, improving efficiency under thermal stress.
Which package does the SK215AH use, and what are its key mechanical features?
The SK215AH uses the DO-214AC (SMA) surface-mount package, with dimensions conforming to JEDEC DO-214AC Issue D. Key features include matte tin-plated leads, UL 94V-0 flammability-rated molding compound, cathode band polarity marking, and JESD201 Class 2 whisker resistance. The package weighs approximately 0.070 g and supports automated placement per the manufacturer's mechanical data sheet for SK215AH.
