Product details

Overview

SK810CHM6G from Taiwan Semiconductor is a single-die, 100 V repetitive peak reverse voltage, 8 A average forward current Schottky barrier rectifier in DO-214AB (SMC) surface-mount package, optimized for high-efficiency switching mode power supplies and DC-DC converters with low forward voltage drop (0.90 V at 8 A, 25°C).

For engineers reviewing the SK810CHM6G datasheet, SK810CHM6G pinout, SK810CHM6G application, or SK810CHM6G equivalent, key selection considerations include its 100 V V_RRM, 150 A non-repetitive surge capability, 10,000 V/µs dV/dt rating, 125–150°C junction temperature range, and RoHS/halogen-free compliance for industrial and adapter designs.

Technical Context

This Schottky rectifier uses a planar metal-silicon junction structure to achieve low conduction loss and fast recovery without minority-carrier storage delay. Its guard ring design enhances ruggedness against transient overvoltage events, and the matte tin-plated leads meet J-STD-002 solderability requirements.

The device operates across –55°C to +150°C storage and junction temperature ranges, with thermal resistance R_θJA of 20°C/W under standard PCB mounting conditions. Reverse leakage remains ≤10 mA at 100°C and rated reverse voltage, supporting stable performance in thermally constrained layouts.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - Maximum repetitive reverse blocking voltage; defines upper limit for DC bus or output rail voltage in SMPS designs
I_F	8 A - Continuous average forward current at T_A = 25°C; derates linearly above 25°C per published curve
V_F	0.90 V @ 8 A, 25°C - Low conduction loss enables >92% efficiency in 12 V–48 V output converters
I_FSM	150 A - Peak non-repetitive surge current (8.3 ms half-sine); supports cold-start and fault-current handling
dV/dt	10,000 V/µs - High critical rate-of-rise immunity prevents false turn-on in high-dV/dt switching nodes
T_J max	150°C - Extended junction temperature rating allows operation in compact, sealed enclosures without forced air
R_θJA	20°C/W - Thermal resistance enables 4.5 W dissipation with ≤90°C rise above ambient on standard 2-layer PCB

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-8EWH10FN-M3/45	Same DO-214AB package, 100 V V_RRM, but 8 A I_F rated at T_A = 115°C (not 25°C); V_F = 0.82 V @ 8 A	Higher thermal rating enables higher ambient operation but requires different derating curve interpretation	Select when board-level ambient exceeds 70°C and thermal management is limited
ON Semiconductor SB8100E	DO-214AB, 100 V, 8 A, but V_F = 0.87 V @ 8 A and I_FSM = 120 A (vs. 150 A)	Lower surge rating reduces margin in high-inrush applications like motor-driven adapters	Select when cost is primary constraint and surge events are infrequent or clamped externally

Compared with VS-8EWH10FN-M3/45 and SB8100E, SK810CHM6G offers superior surge robustness (150 A) and guaranteed 125–150°C junction operation, making it preferred for industrial-grade power supplies where long-term reliability under transient stress is critical.

FAQ

What is the maximum junction temperature rating for SK810CHM6G?

The SK810CHM6G has a maximum junction temperature (T_J) rating of 150°C, with operational range from –55°C to +150°C. This extended rating allows reliable use in enclosed industrial environments where ambient temperatures exceed 85°C. The device's thermal resistance (R_θJA = 20°C/W) ensures predictable derating up to this limit when mounted on standard FR-4 PCBs with recommended copper area.

Is SK810CHM6G RoHS and halogen-free compliant?

Yes, SK810CHM6G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm. This compliance supports export to EU, Japan, and other regulated markets without requiring special exemptions or declarations beyond standard documentation.

What does the "HM6G" suffix indicate in SK810CHM6G?

The "HM6G" suffix in SK810CHM6G denotes Taiwan Semiconductor's tape-and-reel packaging variant: "H" = halogen-free, "M" = moisture sensitivity level 1 (MSL-1), "6" = 3,000 units per reel, and "G" = green compound (RoHS-compliant molding). This matches the ordering code specification in the official datasheet and confirms full compliance with J-STD-020 and JEDEC standards.

How does the guard ring feature improve reliability in SK810CHM6G?

The guard ring in SK810CHM6G is a diffused p-type region surrounding the active Schottky junction, which distributes electric field stress away from the junction periphery. This prevents premature edge breakdown during voltage transients, enabling stable operation at 100 V V_RRM with 10,000 V/µs dV/dt immunity. It directly contributes to the device's ability to withstand repeated surge events without parameter drift.

Can SK810CHM6G replace SK86C in an existing design?

No - SK810CHM6G (100 V V_RRM) is not a direct replacement for SK86C (60 V V_RRM) without circuit review. While both share DO-214AB packaging and 8 A I_F, the higher reverse voltage rating increases junction capacitance and slightly raises forward voltage (0.90 V vs. ~0.75 V for SK86C). Substitution may cause excessive conduction loss or reduced efficiency if the original design operates near the 60 V limit.
