Product details
Overview
SK56C V7G from Taiwan Semiconductor is a 5A, 60V Schottky barrier surface-mount rectifier in DO-214AB (SMC) package, optimized for high-efficiency switching power supplies with low forward voltage (0.75 V at 5 A, 25°C) and high surge capability (120 A IFSM). It features guard ring overvoltage protection, moisture sensitivity level 1, and RoHS/halogen-free compliance.
For engineers reviewing the SK56C V7G datasheet, SK56C V7G pinout, SK56C V7G application, or SK56C V7G equivalent, key selection criteria include its 60 V repetitive peak reverse voltage, 0.75 V forward drop at rated current, 13 °C/W junction-to-lead thermal resistance, and suitability for compact, thermally constrained SMPS and adapter designs.
Technical Context
The SK56C V7G implements a single-die Schottky junction with metal-semiconductor contact enabling fast recovery (no minority carrier storage) and zero reverse recovery charge. Its 60 V VRRM rating targets mid-voltage DC-DC conversion stages where efficiency and thermal management are critical.
Thermal performance is defined by RθJL = 13 °C/W on a 16 mm × 16 mm Cu pad PCB, supporting continuous 5 A conduction without forced cooling. The cathode band polarity marking and matte tin-plated leads ensure reliable automated assembly per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage; defines safe operating range in buck/boost output rectification |
| IF | 5 A - Continuous forward current rating; supports typical 60–100 W SMPS output stages |
| VF @ 5 A, 25°C | 0.75 V - Low conduction loss enables >92% efficiency in 12 V output converters |
| IFSM | 120 A - Peak non-repetitive surge current handling for line transient immunity |
| RθJL | 13 °C/W - Enables direct thermal path to PCB copper; limits junction rise to ~65°C at 5 A ambient |
| IR @ 60 V, 25°C | 0.5 mA - Low leakage preserves light-load efficiency and reduces standby power |
| TJ max | 150 °C - Allows operation in sealed enclosures up to 85°C ambient with margin |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS56HE3/5BT | Same 60 V VRRM, 5 A IF, but VF = 0.72 V (typ); DO-214AC (SMA) package, smaller footprint | Lower thermal mass; less suitable for sustained 5 A loads without enhanced copper | Select when board space is constrained and average current < 3.5 A |
| MBR560FCT | 60 V VRRM, 5 A IF, VF = 0.74 V (typ); TO-277 package, no leaded option | Higher RθJA (65 °C/W); requires larger thermal pad or airflow | Select when lead-free SMT-only assembly is required and thermal design accommodates higher rise |
Compared with SS56HE3/5BT and MBR560FCT, the SK56C V7G offers superior thermal coupling via DO-214AB's larger copper interface (RθJL = 13 °C/W), making it preferred for continuous 5 A operation in compact, convection-cooled industrial and adapter designs.

FAQ
What is the maximum junction temperature rating for SK56C V7G?
The SK56C V7G has a maximum junction temperature (TJ max) of 150 °C, allowing reliable operation in sealed or high-ambient environments such as enclosed LED drivers and industrial power modules. This rating is validated under specified thermal conditions using a 16 mm × 16 mm PCB copper pad, and must be respected in layout design to avoid derating or premature failure of the SK56C V7G.
Does SK56C V7G have a specified reverse recovery time (trr)?
No-SK56C V7G is a Schottky barrier rectifier and exhibits no minority-carrier storage, so it has effectively zero reverse recovery time (trr) and no reverse recovery charge (QRR). This eliminates switching losses and EMI associated with conventional PN-junction diodes, making the SK56C V7G ideal for high-frequency SMPS designs above 100 kHz where trr would otherwise degrade efficiency.
What does the "V7G" suffix indicate in SK56C V7G?
The "V7G" suffix in SK56C V7G denotes Taiwan Semiconductor's internal revision and environmental compliance code: "V7" indicates version level S2311 per the official datasheet, and "G" confirms halogen-free and RoHS-compliant construction. This marking aligns with TSC's standardized ordering nomenclature and is verified on device top-side laser marking per the DO-214AB package outline.
Can SK56C V7G replace a 1N5822 in an existing design?
SK56C V7G is not a direct replacement for the through-hole 1N5822 due to different package (DO-214AB vs. DO-201AD), thermal profile, and mounting method. While both are 3 A/40 V Schottky rectifiers, the SK56C V7G is rated for 5 A/60 V and requires SMT reflow. Substitution demands PCB redesign, thermal validation, and solder process review-not just electrical equivalence-before implementing SK56C V7G.
Is SK56C V7G suitable for automotive applications?
The SK56C V7G is not qualified to AEC-Q101 or automotive-grade reliability standards and is not recommended for under-hood or safety-critical automotive systems. Taiwan Semiconductor positions this device for industrial, consumer, and lighting applications. For automotive use, designers should select AEC-Q101-certified alternatives; the SK56C V7G remains appropriate only for non-safety, non-automotive contexts such as aftermarket accessories or infotainment power supplies.
