Product details
Overview
SK56C M6G from Taiwan Semiconductor is a 5A, 60V Schottky barrier surface-mount rectifier in DO-214AB (SMC) package, featuring 0.75V forward voltage at 5A/25°C, 120A surge current capability, and guard ring overvoltage protection. It is used in high-efficiency switching mode power supplies and DC-DC converters where low conduction loss and fast recovery are critical.
For engineers reviewing the SK56C M6G datasheet, SK56C M6G pinout, SK56C M6G application, or SK56C M6G equivalent, key selection criteria include its 60V repetitive peak reverse voltage, 150°C maximum junction temperature, moisture sensitivity level 1 rating, RoHS/halogen-free compliance, and suitability for automated SMT placement on industrial and consumer power boards.
Technical Context
The SK56C M6G is a single-die, unidirectional Schottky rectifier optimized for high-frequency switching applications. Its low VF (0.75V typ. @ 5A, 25°C) and high IFSM (120A) enable efficient operation in compact SMPS designs with minimal thermal overhead.
It exhibits 0.5mA max reverse leakage at 60V/25°C and 10mA at 60V/100°C, with dV/dt rating of 10,000 V/µs and thermal resistance RθJL = 13°C/W. The device uses matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS56 (ON Semiconductor) | Same 60V VRRM, 5A IF, but VF = 0.72V typ. @ 5A; slightly lower RθJA (45°C/W vs. 53°C/W) | Identical DO-214AB footprint; preferred where marginally lower VF or tighter thermal budget is required | Select SS56 when optimizing for lowest possible conduction loss in space-constrained layouts with limited copper area |
| SB560 (Diodes Inc.) | 60V VRRM, 5A IF, VF = 0.72V typ.; higher IR = 1.0mA @ 60V/25°C vs. SK56C M6G's 0.5mA | Same package; higher leakage may impact light-load efficiency in battery-powered systems | Choose SB560 only if sourcing flexibility is prioritized and reverse leakage is not critical to standby power budget |
Compared with SS56 and SB560, the SK56C M6G offers the lowest reverse leakage at 60V/25°C (0.5mA), superior surge robustness (120A IFSM), and integrated guard ring-making it optimal for industrial and automotive-grade power supplies requiring long-term reliability under transient stress.

FAQ
What is the maximum junction temperature rating for the SK56C M6G?
The SK56C M6G has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet (Version S2311). This rating enables reliable operation in enclosed industrial power supplies and automotive auxiliary converters where ambient temperatures exceed 70°C. Thermal design must ensure RθJL = 13°C/W path to PCB copper is maintained.
Does the SK56C M6G have a guard ring structure?
Yes, the SK56C M6G incorporates a guard ring for overvoltage protection, explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet (Version S2311). This structure enhances edge termination robustness and improves resistance to transient voltage breakdown-particularly beneficial in flyback and forward converter topologies subject to ringing or load dump events.
What is the forward voltage of the SK56C M6G at 5A and 25°C?
The forward voltage (VF) of the SK56C M6G is 0.75 V (maximum) at IF = 5A and TJ = 25°C, per ELECTRICAL SPECIFICATIONS table in the official datasheet. This value is measured under pulse conditions (PW = 0.3ms) and reflects typical conduction loss in high-frequency switching applications such as SMPS secondary-side rectification.
Is the SK56C M6G RoHS and halogen-free compliant?
Yes, the SK56C M6G is both RoHS compliant and halogen-free, as confirmed in the FEATURES section of the Taiwan Semiconductor datasheet (Version S2311). These compliance attributes meet IPC-1752A reporting standards and support environmental requirements for commercial, industrial, and medical equipment sold in EU, US, and Asia-Pacific markets.
What is the moisture sensitivity level (MSL) of the SK56C M6G?
The SK56C M6G has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it can be stored indefinitely at ≤30°C/60% RH and subjected to standard reflow profiles (e.g., JEDEC J-STD-020 Rev E) without pre-baking. This eliminates handling complexity in high-volume SMT lines and reduces risk of popcorning during assembly.
