Product details
Overview
SK83CHM6G from Taiwan Semiconductor is a 30V, 8A surface-mount Schottky barrier rectifier in DO-214AB (SMC) package, featuring low forward voltage (0.55 V at 8 A, 25°C), high surge current capability (150 A), and junction temperature rating up to +150°C. It serves as a primary output rectifier in high-efficiency AC/DC adapters and DC/DC converters.
For engineers reviewing the SK83CHM6G datasheet, SK83CHM6G pinout, SK83CHM6G application, or SK83CHM6G equivalent, key selection criteria include repetitive peak reverse voltage (30 V), forward voltage drop at rated current, thermal resistance (20 °C/W), surge robustness, and RoHS/halogen-free compliance for industrial power supplies.
Technical Context
This Schottky rectifier uses a single-die construction with guard ring protection to enhance overvoltage ruggedness. Its low VF and high IFSM support high-frequency switching topologies where conduction loss and transient reliability are critical.
The device operates across -55°C to +150°C junction temperature range and meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity requirements-enabling compatibility with standard reflow profiles without baking.
Key Specifications

| VF @ 8A, 25°C | 0.55 V - Low conduction loss reduces heat generation and improves system efficiency above 90% |
| IFSM | 150 A - Non-repetitive surge rating enables reliable startup and fault tolerance in SMPS with high input capacitance |
| RθJA | 20 °C/W - Thermal resistance from junction to ambient; determines heatsink-free operation up to ~3.2 W dissipation at TA = 70°C |
| IR @ 30V, 100°C | 15 mA - Reverse leakage at elevated temperature; impacts standby power in energy-efficient designs |
| TJ max | +150°C - Extended junction temperature rating allows use in thermally constrained enclosures or high-ambient environments |

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-8EWH03FN-M3/45 | Same DO-214AB package, 30 V VRRM, but VF = 0.49 V @ 8 A (25°C); slightly lower RθJA (18 °C/W) | Better efficiency at light loads; tighter VF distribution supports parallel operation | Preferred when optimizing for ultra-low standby loss or multi-phase paralleling |
| ON Semiconductor SB830 | DO-214AB, 30 V, VF = 0.57 V @ 8 A (25°C); TJ max = +125°C (not +150°C) | Limited high-temperature margin; not rated for continuous operation above 125°C junction | Suitable for cost-sensitive consumer adapters with derated thermal design |
Compared with VS-8EWH03FN-M3/45 and SB830, SK83CHM6G offers balanced performance: superior thermal rating (+150°C) versus SB830 and tighter process control than generic alternatives-making it optimal for industrial-grade 8 A rectification where reliability and temperature margin are prioritized over marginal VF reduction.

FAQ
What is the maximum junction temperature rating for SK83CHM6G?
The SK83CHM6G has a maximum junction temperature (TJ max) of +150°C, verified per TSC's L2102 datasheet revision. This extended rating allows reliable operation in high-ambient environments such as enclosed LED drivers or industrial DC/DC modules. The +150°C specification applies across the full rated current range and is validated with thermal testing under JEDEC JESD51-1 conditions. SK83CHM6G maintains stable electrical parameters up to this limit, unlike variants such as SK82C that are rated only to +125°C.
Does SK83CHM6G meet RoHS and halogen-free requirements?
Yes, SK83CHM6G is RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the official Taiwan Semiconductor datasheet (Version L2102). The molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm. These certifications are documented in TSC's material declarations and supported by third-party test reports available upon request for SK83CHM6G.
What is the forward voltage of SK83CHM6G at 8 A and 100°C junction temperature?
The forward voltage (VF) of SK83CHM6G is not specified at 8 A and 100°C in the datasheet; only VF at 25°C (0.55 V) and reverse leakage (IR) at 100°C are provided. However, typical VF increases ~2.2 mV/°C for Schottky diodes-projecting ~0.71 V at 100°C. For precise thermal modeling, engineers should refer to Figure 4 (Typical Forward Characteristics) in the SK82C–SK810C datasheet, which shows VF curves across temperature for SK83C. SK83CHM6G shares identical die characteristics.
Is SK83CHM6G pin-compatible with other SK8xC family members?
Yes, SK83CHM6G is mechanically and electrically pin-compatible with all SK8xC variants (e.g., SK82CHM6G, SK84CHM6G) because they share the same DO-214AB (SMC) package, anode/cathode terminal layout, and polarity marking (cathode band). Voltage rating differences (20–100 V) do not affect pinout or solder footprint. Designers may substitute SK83CHM6G into existing layouts intended for SK8xC parts without PCB changes-provided reverse voltage stress remains ≤30 V.
What packaging format is supplied for SK83CHM6G?
SK83CHM6G is supplied in tape-and-reel format: 3,000 units per reel, compatible with standard SMT pick-and-place equipment. The reel meets EIA-481-D standards, and the carrier tape features embossed pockets with cover tape sealing. Each reel includes traceable lot code and date code (YW format) per the marking diagram in the SK82C–SK810C datasheet. No bulk or ammo-pack options are offered for SK83CHM6G.
