Product details
Overview
SK215AHR3G 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 25°C, 0.1 mA reverse current at rated 150 V and 25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or reverse-battery protection diode in DC/DC converters and car lighting systems.
For engineers reviewing the SK215AHR3G datasheet, SK215AHR3G pinout, SK215AHR3G application, or SK215AHR3G equivalent, key selection criteria include its 150 V repetitive peak reverse voltage, low VF for high-efficiency power conversion, AEC-Q101 qualification, moisture sensitivity level 1 rating, and DO-214AC thermal performance (RθJA = 88°C/W).
Technical Context
The SK215AHR3G employs a single-die Schottky junction optimized for low forward voltage drop and fast switching, with no recovery time and minimal stored charge. Its guard ring structure provides over-voltage protection, and it supports surge currents up to 50 A (8.3 ms half-sine) without degradation.
Rated for junction temperatures up to +150°C and storage from –55°C to +150°C, the device meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability standards. Its matte tin-plated leads ensure solderability per J-STD-002, and polarity is marked by a cathode band.

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-M3/57T | Same 150 V VRRM, 2 A IF, but VF = 0.89 V @ 2 A; DO-214AC package; no AEC-Q101 claim. | Lacks automotive qualification; suitable for industrial DC/DC but requires additional system-level validation for automotive use. | Select when AEC-Q101 is not mandated and lower VF is prioritized over qualification documentation. |
| ON Semiconductor SB2150-E3/54 | 150 V VRRM, 2 A IF, VF = 0.93 V @ 2 A; AEC-Q101 qualified; DO-214AC; IR = 0.2 mA @ 150 V, 25°C. | Higher leakage than SK215AHR3G; may impact ultra-low-power always-on circuits. | Prefer when sourcing flexibility across multiple franchised channels is required, accepting slightly higher reverse leakage. |
Compared with VS-2EY15-M3/57T and SB2150-E3/54, the SK215AHR3G offers the lowest reverse leakage (0.1 mA) among AEC-Q101-qualified 150 V/2 A Schottkys, making it optimal for battery-sensitive automotive modules where standby current must stay below 1 µA per rail.

FAQ
What is the maximum junction temperature rating for SK215AHR3G?
The SK215AHR3G 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 allows the SK215AHR3G to operate reliably in engine bay locations where ambient temperatures exceed 105°C, provided thermal design maintains junction temperature below this limit using the specified RθJA of 88°C/W.
Is SK215AHR3G suitable for reverse battery protection in 24 V commercial vehicle systems?
Yes, the SK215AHR3G is suitable for reverse battery protection in 24 V commercial vehicle systems. Its 150 V VRRM provides 6× margin over nominal 24 V, accommodating ISO 7637-2 load dump pulses up to 120 V. The SK215AHR3G's AEC-Q101 qualification, 0.1 mA reverse leakage at 25°C, and guard ring structure collectively ensure robust protection without false triggering or thermal runaway.
Does SK215AHR3G have a halogen-free and RoHS-compliant construction?
Yes, SK215AHR3G is explicitly stated as halogen-free and RoHS compliant in the Taiwan Semiconductor datasheet Version C2307. The molding compound meets UL 94V-0 flammability rating, and all materials comply with EU Directive 2011/65/EU and IEC 61249-2-21, enabling unrestricted use in global automotive supply chains without substance-of-concern exemptions.
What is the forward voltage of SK215AHR3G at 2 A and 125°C?
The forward voltage of SK215AHR3G at 2 A and 125°C is not explicitly tabulated in the datasheet, but Figure 12 shows typical forward characteristics at TJ = 125°C, indicating VF ≈ 0.82 V at 2 A. This value is derived from the SK215AH curve in the "Typical Forward Characteristics" plot (Page 4, Fig.12), confirming reduced VF at elevated temperature due to Schottky physics-critical for thermal stability in high-ambient automotive applications.
How is polarity indicated on the SK215AHR3G package?
Polarity on the SK215AHR3G is indicated by a visible cathode band located near one end of the DO-214AC (SMA) molded plastic body. Per the package outline drawing (Page 7), this band aligns with the cathode terminal, and the anode is the opposite lead. The marking diagram confirms "GYWF" format with P/N and date code, but the cathode band remains the sole polarity identifier-no silkscreen text or dot is used.
