Product details
Overview
SK510C V7G from Taiwan Semiconductor is a 5A, 100V Schottky barrier surface-mount rectifier in DO-214AB (SMC) package, featuring 0.85V forward voltage at 5A/25°C, 120A surge capability, and 0.3mA reverse leakage at rated VR and 25°C. It serves as a high-efficiency output rectifier in DC-DC converters and offline SMPS.
For engineers reviewing the SK510C V7G datasheet, SK510C V7G pinout, SK510C V7G application, or SK510C V7G equivalent, key selection criteria include its 100V VRRM rating, low VF for thermal efficiency, DO-214AB mechanical compatibility, and JESD201 Class 2 whisker resistance for automated assembly reliability.
Technical Context
The SK510C V7G implements a single-die Schottky junction optimized for fast switching and minimal conduction loss in high-frequency power conversion. Its 100V repetitive peak reverse voltage and 120A non-repetitive surge current support robust operation under transient load conditions.
Thermal performance is defined by RθJL = 13°C/W and RθJA = 53°C/W on a 16mm × 16mm Cu pad PCB, enabling stable 5A continuous operation up to +150°C junction temperature with appropriate board layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum blocking voltage before avalanche; sets upper limit for output rectification in 48V–72V bus systems. |
| IF | 5 A - Continuous forward current rating; defines steady-state power delivery capacity without derating at 25°C ambient. |
| VF @ 5A, 25°C | 0.85 V - Low conduction loss enables >92% efficiency in 12V-output SMPS at full load. |
| IR @ 100V, 25°C | 0.3 mA - Minimal leakage preserves standby power budget in energy-sensitive adapters and lighting drivers. |
| IFSM | 120 A - Withstands 8.3ms half-sine surges; supports hot-plug and inrush events in industrial power modules. |
| TJ max | +150 °C - Enables operation in sealed enclosures or high-ambient environments without forced cooling. |
| RθJL | 13 °C/W - Low junction-to-lead resistance allows direct heat transfer to PCB copper, simplifying thermal design. |

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-50WQ10FN-M3/45 | Same 100V VRRM, 5A IF, but VF = 0.72V @ 5A; TO-220AC package (through-hole) | Requires PCB through-hole mounting and larger heatsink area; unsuitable for high-density SMT designs. | Select when legacy through-hole assembly is mandated or higher surge margin (150A IFSM) is required. |
| ON Semiconductor SB5100-E3/54 | 100V VRRM, 5A IF, VF = 0.87V @ 5A; same DO-214AB package and MSL-1 rating | Identical footprint and reflow profile; minor VF difference has negligible impact on efficiency below 50W. | Drop-in replacement if Taiwan Semiconductor supply is constrained; verify marking and lot traceability per OEM quality plan. |
Compared with VS-50WQ10FN-M3/45 and SB5100-E3/54, the SK510C V7G offers optimal balance of low VF, SMT compatibility, and industrial-grade reliability-making it preferred for space-constrained, high-volume power adapter and converter designs where thermal management and assembly yield are critical.

FAQ
What is the maximum junction temperature rating for the SK510C V7G?
The SK510C V7G has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings in the official TSC datasheet revision S2311. This rating allows continuous 5A operation in sealed enclosures or high-ambient environments when mounted on a 16mm × 16mm Cu pad PCB with proper airflow or heatsinking. Thermal derating begins above 25°C ambient per the forward current derating curve in Figure 1.
Does the SK510C V7G have RoHS and halogen-free compliance?
Yes, the SK510C V7G is RoHS compliant and halogen-free, as explicitly stated in the "Features" section of the TSC datasheet (S2311). The molding compound meets UL 94V-0, and terminals are matte tin plated per J-STD-002. These certifications are confirmed for the DO-214AB (SMC) package variant shipped under ordering code SK510C V7G.
What is the reverse leakage current specification for SK510C V7G at elevated temperature?
At 100V reverse bias and +125°C junction temperature, the SK510C V7G exhibits ≤5mA reverse leakage current (IR), per the Electrical Specifications table in the TSC datasheet. At +25°C, IR is limited to 0.3mA - a value critical for minimizing standby power loss in energy-efficient adapters and lighting drivers.
Is the SK510C V7G suitable for use in automotive applications?
The SK510C V7G is not qualified to AEC-Q101 and is not recommended for automotive powertrain or safety-critical systems. However, it is widely used in automotive infotainment power supplies and body electronics where industrial-grade reliability suffices. TSC explicitly states these devices are "not designed for use in medical, life-saving, or life-sustaining applications," and automotive qualification requires separate validation.
What does the 'V7G' suffix indicate in SK510C V7G?
The 'V7G' suffix in SK510C V7G denotes Taiwan Semiconductor's internal packaging and environmental coding: 'V' indicates tape-and-reel packaging (3,000 units per reel), '7' specifies green compound (halogen-free), and 'G' confirms RoHS compliance. This matches the ordering information table in the S2311 datasheet and distinguishes it from non-RoHS or bulk-packaged variants.
