Product details
Overview
SK520C V7G from Taiwan Semiconductor is a 5A, 200V Schottky barrier surface-mount rectifier in DO-214AB (SMC) package, optimized for high-efficiency switching power supplies with low forward voltage (0.95V at 5A, 25°C), high surge capability (120A IFSM), and junction temperature up to 150°C. It serves as the primary output rectifier in AC/DC adapters and DC/DC converters.
For engineers reviewing the SK520C V7G datasheet, SK520C V7G pinout, SK520C V7G application, or SK520C V7G equivalent, key selection criteria include its 200V reverse voltage rating, 0.95V forward drop at full load, 13°C/W junction-to-lead thermal resistance, moisture sensitivity level 1 compliance, and cathode-band polarity marking for reliable automated assembly.
Technical Context
The SK520C V7G implements a single-die Schottky barrier structure with guard ring overvoltage protection, enabling stable operation under repetitive transient stress. Its 10,000 V/µs critical dV/dt rating supports fast-switching topologies without spurious turn-on.
Thermal performance is characterized on a 16 mm × 16 mm PCB copper pad: RθJA = 53°C/W, RθJC = 16°C/W, and RθJL = 13°C/W - confirming suitability for thermally constrained SMT layouts where lead conduction dominates heat removal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum non-repetitive reverse blocking voltage; defines safe operating margin in 170–200 VDC output rails. |
| IF | 5 A continuous - Rated average forward current at case temperature ≤ 110°C; supports sustained 60W+ converter outputs. |
| VF | 0.95 V @ 5 A, 25°C - Low conduction loss enables >92% efficiency in 12–48 V output stages. |
| IFSM | 120 A @ 8.3 ms - Withstands inrush and fault currents without bond-wire fusing. |
| TJ max | 150°C - Enables operation in sealed enclosures or high-ambient industrial environments. |
| RθJL | 13°C/W - High thermal conductivity via leads allows effective heat transfer to PCB ground/power planes. |
| IR | 0.3 mA @ 200 V, 25°C - Low leakage preserves light-load efficiency and reduces standby power. |

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-50WQ03FNTR-M3 | 30 V VRRM, 5 A, 0.41 V VF; TO-220AC package, higher thermal mass but through-hole only. | Not suitable for 200 V systems; limited to low-voltage DC/DC outputs. | Select only when lower VF and higher thermal inertia outweigh SMT compatibility needs. |
| ON Semiconductor SB5200-E3/54 | 200 V VRRM, 5 A, 0.92 V VF; same DO-214AB package, but 150°C TJ max and 0.5 mA IR @ 200 V. | Higher leakage may impact ultra-low-power standby; otherwise functionally aligned. | Valid alternative where tighter VF tolerance or alternate qualification history is required. |
Compared with SK520C V7G, the VS-50WQ03FNTR-M3 offers lower forward drop but lacks voltage rating and mounting compatibility, while SB5200-E3/54 matches voltage and package but exhibits slightly higher reverse leakage - making SK520C V7G preferable for high-temperature, low-leakage 200 V rectification.

FAQ
What is the maximum junction temperature rating for SK520C V7G?
The SK520C V7G has a maximum junction temperature (TJ) of 150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet revision S2311. This rating allows continuous operation in enclosed or high-ambient environments when thermal design respects RθJA = 53°C/W on standard test board conditions. Derating curves in Figure 1 confirm usable current down to 125°C case temperature.
Does SK520C V7G have RoHS and halogen-free compliance?
Yes, SK520C V7G is RoHS compliant and halogen-free, as explicitly stated in the "Features" section of the Taiwan Semiconductor datasheet (Version S2311). The molding compound meets UL 94V-0 flammability rating, and all materials comply with JEDEC J-STD-020 moisture sensitivity level 1 - eliminating bake requirements prior to reflow.
What is the forward voltage of SK520C V7G at rated current and temperature?
The forward voltage (VF) of SK520C V7G is 0.95 V at IF = 5 A and TJ = 25°C, measured under pulse test conditions (PW = 0.3 ms). At elevated junction temperatures (e.g., 125°C), VF decreases slightly due to Schottky barrier physics, remaining below 0.88 V per typical characteristics curve Fig.10 in the SK52C–SK520C datasheet.
Is SK520C V7G suitable for use in automotive applications?
No, SK520C V7G is not qualified for automotive applications. Taiwan Semiconductor's notice on page 7 of the S2311 datasheet explicitly states: "The products shown herein are not designed for use in medical, life-saving, or life-sustaining applications." It carries no AEC-Q101 qualification, and its temperature range (-55°C to +150°C) lacks automotive-grade screening or PPAP documentation.
What packaging and reel quantity is offered for SK520C V7G?
SK520C V7G is supplied in DO-214AB (SMC) package on tape-and-reel format, with 3,000 units per reel, as confirmed in the "Ordering Information" section of the Taiwan Semiconductor datasheet (Version S2311). The marking code "SK520C" appears on the device body, with "V7G" denoting a specific date/lot traceability variant per internal TSC coding convention.
