Product details
Overview
SK56C R7G 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, J-STD-020 Level 1 moisture sensitivity, and RoHS/halogen-free compliance.
For engineers reviewing the SK56C R7G datasheet, SK56C R7G pinout, SK56C R7G application, or SK56C R7G equivalent, key selection factors include its 60 V VRRM rating, 0.75 V VF at rated current, 10 mA IR at 100°C, 13°C/W RθJL thermal resistance, and suitability for compact, thermally constrained SMPS and DC-DC converter designs.
Technical Context
The SK56C R7G is a single-die, unidirectional Schottky rectifier designed for freewheeling and output rectification in high-frequency switching topologies. Its 60 V repetitive peak reverse voltage and 10,000 V/µs dV/dt rating support stable operation in fast-switching converters up to several hundred kHz.
Thermal performance is defined by junction-to-lead resistance of 13°C/W on standard PCB mounting (16 mm × 16 mm Cu pad), enabling reliable 5 A continuous conduction without forced cooling. The device operates across –55°C to +150°C junction temperature range and meets JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum reverse blocking voltage; sets upper limit for output rectification in 48 V input or 24 V output SMPS stages |
| IF | 5 A - Continuous forward current rating; defines steady-state power handling in TO-220–class replacement applications |
| VF @ 5 A, 25°C | 0.75 V - Low conduction loss; reduces power dissipation to ≤3.75 W at full load, easing thermal design |
| IFSM (8.3 ms) | 120 A - Peak non-repetitive surge rating; withstands startup inrush and transient overload without failure |
| IR @ 60 V, 100°C | 10 mA - Reverse leakage at elevated temperature; impacts standby efficiency and thermal runaway margin |
| RθJL | 13 °C/W - Junction-to-lead thermal resistance; enables direct heat transfer to PCB copper, supporting compact layout |
| TJ Range | –55°C to +150°C - Wide operating junction temperature; supports industrial and automotive under-hood environments |

| 10,000 V/µs dV/dt rating | Ensures stable turn-off behavior in hard-switched converters with steep voltage edges, preventing false turn-on |
| Halogen-free & RoHS | Meets global environmental compliance requirements for consumer, industrial, and telecom end equipment |
Applications
| AC-DC Adapters | DC-DC Converters |

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-50SQ060NTRP | Same 60 V VRRM, 5 A IF, but VF = 0.67 V (typ) at 5 A; slightly lower RθJA (45°C/W vs. 53°C/W) | Better efficiency at light loads due to lower VF; requires identical DO-214AB footprint | Preferred where <0.1% efficiency gain justifies minor cost premium and sourcing diversification |
| ON Semiconductor SB560-E3/54 | 60 V VRRM, 5 A IF, VF = 0.72 V (max) at 5 A; IR = 0.5 mA @ 25°C (lower leakage than SK56C R7G's 0.5 mA typ) | Lower room-temp leakage improves standby power in energy-sensitive applications (e.g., IoT gateways) | Recommended when ultra-low IR at 25°C is prioritized over high-temperature IR performance |
Compared with VS-50SQ060NTRP and SB560-E3/54, the SK56C R7G offers superior high-temperature reverse leakage control (10 mA @ 100°C vs. unspecified for alternatives) and integrated guard ring protection-critical for robustness in unregulated industrial environments.

FAQ
What is the maximum junction temperature rating for SK56C R7G?
The SK56C R7G has a maximum junction temperature (TJ MAX) of +150°C, allowing continuous operation in high-ambient environments such as enclosed industrial power supplies or LED driver housings. This rating is validated per absolute maximum ratings table and supported by thermal derating curves showing 5 A operation down to 100°C ambient on standard PCB mounting.
Does SK56C R7G have a specified reverse recovery time (trr)?
No-SK56C R7G is a Schottky barrier rectifier and exhibits no minority-carrier storage; therefore, it has no defined reverse recovery time (trr). Its switching is inherently soft and fast, with only junction capacitance (typically ~150 pF at 4 V) limiting high-frequency performance-making it ideal for >100 kHz SMPS designs without snubber circuits.
What does the "R7G" suffix indicate in SK56C R7G?
The "R7G" suffix in SK56C R7G denotes tape-and-reel packaging (R7 = 3,000 pcs/reel per TSC ordering guide) and green (halogen-free) compound (G), confirming compliance with RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity Level 1. It does not affect electrical specifications.
Can SK56C R7G replace SK54C in an existing design?
Yes-SK56C R7G is pin-compatible and footprint-identical to SK54C (40 V VRRM), but offers higher 60 V reverse blocking. Substitution is safe if system peak reverse voltage remains ≤60 V; however, VF increases slightly (0.75 V vs. 0.55 V for SK54C), raising conduction loss by ~0.35 W at 5 A-verify thermal margin in the target layout.
Is SK56C R7G suitable for automotive applications?
The SK56C R7G is not AEC-Q101 qualified and is not recommended for safety-critical automotive applications (e.g., ADAS, powertrain). However, it is used in non-safety automotive subsystems such as infotainment power supplies or cabin lighting drivers where industrial-grade reliability suffices and ambient temperatures remain within –40°C to +105°C case limits.
