Product details
Overview
SK36AHR3G from Taiwan Semiconductor is a 3 A, 60 V Schottky barrier rectifier in DO-214AC (SMA) package, qualified to AEC-Q101, with 0.72 V forward voltage at 3 A and 25 °C, 200 µA reverse current at rated VR and 25 °C, and 70 A surge capability - used in automotive DC/DC converters and reverse battery protection circuits.
For engineers reviewing the SK36AHR3G datasheet, SK36AHR3G pinout, SK36AHR3G application, or SK36AHR3G equivalent, this page delivers verified electrical parameters, thermal resistance values, junction temperature limits, polarity marking details, and AEC-Q101 qualification status for automotive-grade power design validation.
Technical Context
The SK36AHR3G implements a single-die Schottky junction optimized for low VF and fast switching in high-frequency power conversion. Its 60 V VRRM rating and 10,000 V/µs dV/dt support robust operation in noisy automotive environments.
Thermally, it features 25 °C/W junction-to-lead (RθJL) and 66 °C/W junction-to-ambient (RθJA) resistance, enabling reliable 3 A continuous conduction at ≤150 °C junction temperature with appropriate PCB copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - maximum repetitive reverse voltage before breakdown; defines safe operating range in 12 V/24 V automotive systems with transient spikes. |
| IF | 3 A - continuous forward current rating at TA = 25 °C; derates linearly above 25 °C per published curve. |
| VF @ 3 A, 25 °C | 0.72 V - forward voltage drop determining conduction loss (2.16 W max at 3 A); enables >90% efficiency in compact DC/DC stages. |
| IR @ 60 V, 25 °C | 200 µA - leakage current defining standby power loss in reverse-biased configurations like reverse battery protection. |
| IFSM | 70 A - non-repetitive surge current (8.3 ms half-sine); withstands load dump transients without failure. |
| TJ max | +150 °C - maximum junction temperature; supports under-hood deployment with proper thermal management. |
| RθJL | 25 °C/W - thermal resistance from junction to lead; enables direct heatsinking via PCB copper pour or metal-core substrate. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS36H (ON Semiconductor) | Same 60 V VRRM, 3 A IF, DO-214AC package; VF = 0.7 V typical at 3 A, 25 °C; no AEC-Q101 claim in public datasheet. | Not certified for automotive use; suitable for industrial/commercial DC/DC where qualification is not mandated. | Select SS36H only if AEC-Q101 is not required and cost optimization is prioritized. |
| SB360-TB (Diodes Inc.) | 60 V VRRM, 3 A IF, DO-214AC; VF = 0.72 V max at 3 A, 25 °C; AEC-Q101 qualified; IR = 200 µA max at 25 °C. | Functionally aligned with SK36AHR3G for automotive reverse protection and DC/DC; identical parametric envelope. | SB360-TB is a direct functional alternative with matching qualification and performance; verify tape-and-reel packaging compatibility. |
Compared with SS36H and SB360-TB, the SK36AHR3G provides guaranteed AEC-Q101 compliance and documented 200 µA IR at 25 °C - critical for low-leakage reverse protection in always-on automotive modules where quiescent current budgets are sub-100 µA.

FAQ
What is the maximum junction temperature rating for SK36AHR3G?
The SK36AHR3G has a maximum junction temperature (TJ) of +150 °C, validated per absolute maximum ratings in the official TSC datasheet. This rating enables operation in under-hood automotive environments when mounted on PCBs with adequate copper area or thermal vias. Derating curves confirm usable current capacity down to 0 A at 150 °C ambient with no heatsink.
Is SK36AHR3G AEC-Q101 qualified?
Yes, SK36AHR3G is explicitly AEC-Q101 qualified as stated in the "Features" section of the Taiwan Semiconductor datasheet (Version B2304). This qualification covers stress tests including HTGB, HTRB, TCT, and ESD, confirming suitability for automotive power applications such as body control modules and lighting drivers.
What is the forward voltage of SK36AHR3G at 3 A and 100 °C junction temperature?
The SK36AHR3G forward voltage increases with temperature: while VF is 0.72 V max at 3 A and 25 °C, the datasheet does not specify a maximum VF at 100 °C. However, typical VF curves show ~0.62 V at 3 A and 100 °C - a reduction due to Schottky's negative temperature coefficient, confirmed in Figure 4 of the TSC document.
Does SK36AHR3G have a halogen-free and RoHS-compliant construction?
Yes, SK36AHR3G is both halogen-free and RoHS compliant, as confirmed in the "Features" list of the official Taiwan Semiconductor datasheet. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated - satisfying automotive OEM environmental and assembly requirements.
What is the marking code and packaging format for SK36AHR3G?
The SK36AHR3G is marked "SK36A" on the device body and supplied in DO-214AC (SMA) package. It ships in 7,500-piece tape-and-reel format per the ordering information table - compatible with standard high-speed pick-and-place equipment used in automotive electronics manufacturing.
