Product details
Overview
SK56C R6 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). It serves as an output rectifier in AC/DC adapters and DC/DC converters where low conduction loss and thermal robustness are critical.
For engineers reviewing the SK56C R6 datasheet, SK56C R6 pinout, SK56C R6 application, or SK56C R6 equivalent, key selection criteria include its 60 V repetitive peak reverse voltage, 13 °C/W junction-to-lead thermal resistance, cathode-band polarity marking, and RoHS/halogen-free compliance for industrial and lighting power designs.
Technical Context
The SK56C R6 is a single-die Schottky rectifier designed for unidirectional current flow in high-frequency switching topologies. Its guard ring structure provides overvoltage protection, while its JESD201 Class 2 whisker-resistant matte tin plating ensures reliable solderability on automated assembly lines.
Operating across –55°C to +150°C junction temperature range, it delivers stable performance under transient load conditions-evidenced by 120 A non-repetitive surge rating (8.3 ms half-sine) and 10,000 V/µs critical dV/dt rating-making it suitable for compact, thermally constrained SMPS layouts.
Key Specifications

| IF | 5 A - Continuous forward current rating; determines minimum trace width and heatsinking in PCB layout |
| VF | 0.75 V @ 5 A, 25°C - Low conduction loss reduces power dissipation and improves system efficiency |
| IFSM | 120 A - Peak surge current handling enables robust startup and fault tolerance without derating |
| RθJL | 13 °C/W - Junction-to-lead thermal resistance supports direct copper pad mounting for effective heat transfer |

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-50WQ06FNTR-M3 | Same 60 V VRRM, 5 A IF, but TO-220AC package (not SMC); VF = 0.62 V @ 5 A | Requires through-hole mounting and larger board area; better thermal dissipation via heatsink | Select when higher thermal margin is needed and surface-mount constraint is relaxed |
| ON Semiconductor SB560-E3/54 | DO-201AD package (larger than SMC); 60 V VRRM, 5 A IF, VF = 0.72 V @ 5 A | Lower power density; less suitable for ultra-thin adapters due to height and footprint | Choose if legacy DO-201AD footprint compatibility is required in redesigns |
Compared with VS-50WQ06FNTR-M3 and SB560-E3/54, the SK56C R6 offers superior board-space efficiency in DO-214AB (SMC), tighter thermal coupling to PCB copper, and automated placement readiness-critical for high-volume, space-constrained power adapter production.

FAQ
What is the maximum junction temperature rating for the SK56C R6?
The SK56C R6 has a maximum junction temperature (TJ) of +150°C, enabling reliable operation in enclosed power supplies and high-ambient-temperature environments such as LED luminaires and industrial control cabinets. This rating is validated per JEDEC test conditions and supports continuous 5 A conduction when properly mounted on a 16 mm × 16 mm copper pad.
Does the SK56C R6 have a specified moisture sensitivity level (MSL)?
Yes, the SK56C R6 is rated MSL Level 1 per J-STD-020, meaning it can be stored indefinitely at ≤30°C/85% RH and does not require baking prior to reflow soldering. This simplifies manufacturing logistics and eliminates yield risk from moisture-induced popcorning during assembly.
What is the forward voltage drop of the SK56C R6 at rated current?
The SK56C R6 exhibits a typical forward voltage (VF) of 0.75 V at 5 A and 25°C junction temperature, measured under pulsed conditions (0.3 ms pulse width). This low VF directly reduces conduction losses and improves overall system efficiency in high-current output stages.
Is the SK56C R6 RoHS and halogen-free compliant?
Yes, the SK56C R6 meets RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21, with no brominated flame retardants or chlorine-based compounds in its molding compound or terminations-ensuring compliance for export to EU, China, and other regulated markets.
How is polarity indicated on the SK56C R6 package?
Polarity is clearly marked on the SK56C R6 via a molded cathode band on the DO-214AB (SMC) case. The banded end corresponds to the cathode terminal, and the opposite end is the anode-this visual indicator aligns with IPC-7351 standards and supports automated optical inspection (AOI) during SMT placement.
