Product details
Overview
SK59C V6G from Taiwan Semiconductor is a 5A, 90V 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 a primary output rectifier in AC/DC adapters and DC/DC converters.
For engineers reviewing the SK59C V6G datasheet, SK59C V6G pinout, SK59C V6G application, or SK59C V6G equivalent, key selection criteria include its 90 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 SK59C V6G implements a single-die Schottky junction with guard ring overvoltage protection and matte tin-plated leads compliant with J-STD-002 solderability. Its 120 A non-repetitive surge rating supports transient load conditions in SMPS outputs.
Thermal performance is characterized on a 16 mm × 16 mm copper pad PCB: RθJA = 53°C/W, RθJC = 16°C/W, enabling reliable operation at full 5 A DC current within -55°C to +150°C junction range without derating below 100°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 90 V - Maximum repetitive reverse blocking voltage; defines safe operating margin in 48 V-output SMPS designs |
| IF | 5 A - Continuous forward current rating; supports typical 60–75 W adapter output stages |
| VF | 0.85 V @ 5 A, 25°C - Low conduction loss improves efficiency vs. standard PN diodes (typically >0.95 V) |
| IR | 0.3 mA @ 90 V, 25°C - Low leakage preserves standby power in energy-efficient adapters |
| IFSM | 120 A @ 8.3 ms - Withstands inrush and short-circuit surges without failure |
| TJ max | +150°C - Enables high-density layout with minimal heatsinking in enclosed enclosures |
| RθJL | 13°C/W - Low junction-to-lead resistance allows direct thermal transfer to PCB copper pour |

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-50SQ030NTRP | 30 V VRRM, 5 A, 0.42 V VF - lower voltage rating, lower forward drop | Not suitable for 48 V+ output rails; limited to ≤24 V systems | Select only when VRRM margin < 2× system voltage and ultra-low VF is critical |
| ON Semiconductor SB590-E3/54 | 90 V VRRM, 5 A, 0.87 V VF, same DO-214AB package - near-identical electrical specs | Compatible in same PCB footprint; slightly higher VF increases conduction loss by 0.01 W | Drop-in alternative with identical mounting and thermal interface; verify IR spec (0.5 mA max vs. SK59C's 0.3 mA) |
Compared with VS-50SQ030NTRP and SB590-E3/54, the SK59C V6G delivers tighter reverse leakage (0.3 mA), better thermal resistance (RθJL = 13°C/W), and guard ring protection - making it preferred for 48–60 V output SMPS where reliability under voltage transients is critical.

FAQ
What is the maximum junction temperature rating for SK59C V6G?
The SK59C V6G has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings table in the official TSC datasheet Version S2311. This rating enables operation in thermally constrained environments such as sealed power adapters or industrial modules without active cooling. The SK59C V6G maintains specified electrical performance across the full -55°C to +150°C junction range.
Does SK59C V6G have a specified reverse recovery time (trr)?
No - the SK59C V6G is a Schottky barrier rectifier and exhibits no minority-carrier storage; therefore, reverse recovery time is effectively zero and not specified in the datasheet. This eliminates switching losses and EMI associated with PN diode recovery, making the SK59C V6G ideal for high-frequency SMPS designs above 100 kHz. The SK59C V6G relies on majority-carrier conduction only.
Is SK59C V6G halogen-free and RoHS-compliant?
Yes - the SK59C V6G meets both RoHS Directive 2011/65/EU and halogen-free requirements per JEDEC JS709B, as confirmed in the "Features" section of the TSC datasheet. The molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm. This compliance applies to the SK59C V6G as shipped and certified by Taiwan Semiconductor.
What is the cathode marking method on SK59C V6G?
The cathode of the SK59C V6G is indicated by a molded band on the DO-214AB (SMC) package body, consistent with industry-standard polarity identification. The band aligns with the cathode terminal, which is electrically connected to the larger metallized area on the internal die. This marking is visible under standard AOI inspection and matches the polarity diagram in the TSC package outline drawing (HQ2SD07-DO214SMC-036 REV A).
What is the moisture sensitivity level (MSL) for SK59C V6G?
The SK59C V6G has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH without baking prior to reflow. This eliminates floor-life constraints and simplifies SMT line logistics. The MSL rating is confirmed in the "Features" section of the TSC SK52C–SK520C datasheet and applies to all variants including SK59C V6G.
