Product details
Overview
SK510C M6G from Taiwan Semiconductor is a 5A, 100V Schottky barrier surface-mount rectifier in DO-214AB (SMC) package, optimized for high-efficiency switching power supplies with low forward voltage (0.85 V at 5 A, 25°C), high surge capability (120 A), and junction temperature up to 150°C. It serves as the output rectifier in AC/DC adapters and DC/DC converters.
For engineers reviewing the SK510C M6G datasheet, SK510C M6G pinout, SK510C M6G application, or SK510C M6G equivalent, key selection criteria include its 100 V repetitive peak reverse voltage, 0.85 V forward drop at rated current, 0.3 mA reverse leakage at 25°C, thermal resistance (RθJL = 13°C/W), and DO-214AB mechanical compatibility with automated SMT placement.
Technical Context
The SK510C M6G implements a single-die Schottky junction structure with guard ring overvoltage protection, enabling robust operation under transient voltage stress. Its low forward voltage and high IFSM rating support high-frequency, high-efficiency topologies such as synchronous flyback and active clamp forward converters.
Thermal performance is characterized on a 16 mm × 16 mm copper pad PCB: RθJA = 53°C/W and RθJC = 16°C/W confirm suitability for thermally constrained industrial and lighting applications. Moisture sensitivity level is J-STD-020 Level 1 - no bake required prior to reflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum non-repetitive reverse blocking voltage; defines safe operating margin in 48 V output SMPS designs |
| IF | 5 A continuous - rated average forward current at 150°C junction temperature; supports sustained load in compact adapters |
| VF | 0.85 V @ 5 A, 25°C - low conduction loss improves efficiency and reduces heatsink requirements |
| IFSM | 120 A @ 8.3 ms half-sine - withstands inrush and fault currents without failure in converter primary-side rectification |
| RθJL | 13 °C/W - low junction-to-lead thermal resistance enables direct PCB copper pour heat spreading without external heatsinks |
| IR | 0.3 mA @ 100 V, 25°C - low leakage preserves efficiency in standby mode and high-impedance feedback paths |

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-50WQ10FNTR-M3 | Same 100 V VRRM, 5 A IF, but VF = 0.72 V @ 5 A (lower loss); DO-214AB package; higher IFSM = 150 A | Better efficiency in high-duty-cycle applications; tighter thermal budget in enclosed adapters | Select when optimizing for lowest conduction loss and highest surge margin; verify layout clearance for slightly larger body dimensions |
| ON Semiconductor SB5100-E3/54 | 100 V VRRM, 5 A IF, VF = 0.82 V @ 5 A; DO-214AA (SMB) package - smaller footprint but higher RθJA = 65°C/W | Space-constrained designs where board area is critical; lower thermal performance limits max ambient | Choose for compact portable chargers where size outweighs thermal headroom; derate IF above 60°C ambient |
Compared with SK510C M6G, VS-50WQ10FNTR-M3 offers superior surge and conduction performance at minor cost premium, while SB5100-E3/54 trades thermal capability for footprint reduction - both require validation of PCB thermal relief and solder mask defined pads.

FAQ
What is the maximum junction temperature rating for SK510C M6G?
The SK510C M6G has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings in the official TSC datasheet revision S2311. This rating enables reliable operation in enclosed power supplies and high-ambient industrial environments when mounted on a 16 mm × 16 mm Cu pad. Thermal design must ensure steady-state TJ remains below this limit under worst-case load and ambient conditions. The SK510C M6G datasheet provides derating curves confirming usable current down to 0 A at 150°C ambient with proper PCB copper area.
Does SK510C M6G have a halogen-free and RoHS-compliant construction?
Yes, the SK510C M6G is explicitly certified halogen-free and RoHS-compliant per the TSC product documentation (Version S2311). The molding compound contains no brominated flame retardants, chlorine, or fluorine above threshold limits, and lead content complies with EU Directive 2011/65/EU. This makes SK510C M6G suitable for export to EU, China, and other regulated markets requiring full substance declarations. The SK510C M6G marking code includes "G" to denote green compound per TSC internal coding convention.
What is the reverse leakage current specification for SK510C M6G at elevated temperature?
The SK510C M6G exhibits ≤5 mA reverse leakage current (IR) at rated VRRM = 100 V and TJ = 125°C, per electrical specifications table in the TSC datasheet. At 25°C, IR is ≤0.3 mA - critical for light-load efficiency in burst-mode SMPS. These values were measured using 30 ms pulse test conditions to avoid self-heating artifacts. Designers should reference the reverse characteristics curves (Fig. 7–10) in the SK510C M6G datasheet for temperature-dependent leakage modeling across the full -55°C to +125°C operating range.
Is SK510C M6G compatible with lead-free reflow profiles?
Yes, SK510C M6G is qualified for standard lead-free reflow per J-STD-020, with peak temperature tolerance up to 260°C for 30 seconds. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the device carries J-STD-020 Level 1 moisture sensitivity - meaning it can be placed directly from dry pack without baking. The SK510C M6G package outline and thermal performance data assume JEDEC-standard reflow profile with ramp rates and soak times aligned to IPC/JEDEC J-STD-020D. No special flux or nitrogen atmosphere is required.
What does the "M6G" suffix indicate in SK510C M6G?
The "M6G" suffix in SK510C M6G denotes Taiwan Semiconductor's internal packaging and environmental coding: "M6" specifies tape-and-reel packaging with 3,000 units per reel, and "G" indicates halogen-free green compound per TSC's material designation system. This matches the ordering information table in the SK510C M6G datasheet (Version S2311), where "SK5xC" is the base part number and suffixes define packing method and environmental compliance. The SK510C M6G marking on the device body includes "SK510C" and date/factory codes - no functional difference from SK510C without suffix.
