Product details
Overview
SK810CHR7G from Taiwan Semiconductor is a single-die, 8A, 100V Schottky barrier rectifier in DO-214AB (SMC) 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) and high surge capability (150 A, 8.3 ms).
For engineers reviewing the SK810CHR7G datasheet, SK810CHR7G pinout, SK810CHR7G application, or SK810CHR7G equivalent, key selection criteria include repetitive peak reverse voltage (100 V), junction temperature range (–55°C to +150°C), thermal resistance (20°C/W), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance.
Technical Context
This Schottky rectifier uses a planar silicon die structure with guard ring protection to suppress avalanche breakdown under transient overvoltage conditions. Its low VF and high IFSM support high-frequency, high-current operation in compact power stages.
The device operates across –55°C to +150°C junction temperature, with thermal performance validated by RθJA = 20°C/W and JESD201 Class 2 whisker resistance. Polarity is marked by a cathode band on the DO-214AB case.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum non-repetitive reverse blocking voltage; defines safe operating limit in flyback or buck converter freewheeling paths |
| IF | 8 A - Continuous average forward current at TA = 25°C; derates linearly above 25°C per Fig.1 |
| IFSM | 150 A - Peak non-repetitive surge current (8.3 ms half-sine); supports inrush and fault-current handling |
| VF | 0.90 V - Forward voltage at IF = 8 A, TJ = 25°C; directly determines conduction loss and thermal load |
| RθJA | 20 °C/W - Junction-to-ambient thermal resistance; used to calculate max allowable power dissipation in open-air PCB layout |
| TJ max | +150 °C - Maximum junction temperature; enables operation in high-ambient industrial environments without derating |
| MSL | Level 1 (per J-STD-020) - No floor life limitation; suitable for standard SMT reflow without dry pack or baking |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, matte tin-plated leads, polarity indicated by cathode band, weight ≈ 0.210 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter); must be routed with low-inductance copper |
| Cathode | Forward current exit / reverse voltage terminal | Connected to output rail or ground return; cathode band marks this terminal for correct orientation during placement |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring overvoltage protection | Prevents localized avalanche failure during voltage transients, improving reliability in unregulated input stages |
| Low forward voltage (0.90 V @ 8 A) | Reduces conduction loss by ~15–20% vs. comparable 100 V Si diodes, lowering heatsink requirements |
| High surge current (150 A) | Withstands repeated cold-start surges and short-circuit events without bond-wire fusing |
| Moisture sensitivity Level 1 | Eliminates pre-bake requirement before reflow, reducing manufacturing cycle time and cost |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally regulated end equipment |
Applications
| AC-DC Adapter Power Stage | Industrial DC-DC Converter Output Rectification |
|---|---|
Use Scenario: Secondary-side rectification in 36–75 W wall adapters with universal AC input and 5–24 V DC output. IC Role / Device Role / Timing Role: Freewheeling Schottky rectifier replacing fast recovery diodes to reduce losses and improve efficiency above 85%.

IC Role / Device Role / Timing Role: High-current, high-temperature rectifier in continuous conduction mode (CCM) operation. Use Value: +150°C TJ max and 20°C/W RθJA allow stable operation at 70°C ambient without forced air cooling. |
| LED Driver Secondary Rectification | Telecom Power Supply Input Protection |
Use Scenario: Constant-current LED driver for street lighting, operating from 300–400 V DC bus with 350 mA–1.5 A output. IC Role / Device Role / Timing Role: Output rectifier in flyback-derived topology, handling pulsed forward current with minimal voltage overshoot. Use Value: Guard ring design prevents premature breakdown during line transients, extending lifetime in outdoor deployments. | Use Scenario: Input-stage reverse-polarity and surge protection in 48 V telecom rectifiers with hot-swap capability. IC Role / Device Role / Timing Role: Clamping and freewheeling diode in OR-ing and hold-up circuits. Use Value: 150 A IFSM withstands 10/1000 µs surge events per IEC 61000-4-5, reducing need for parallel devices. |
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, 8 A/100 V, but VF = 0.82 V @ 8 A (TJ = 125°C); higher leakage (1.0 mA @ 100 V, 125°C) | Better conduction loss at elevated temperature; less suitable for high-temperature, low-leakage standby modes | Preferred where thermal management is constrained and TJ > 100°C is common |
| ON Semiconductor SB8100E | DO-214AB, 8 A/100 V, VF = 0.88 V @ 8 A (25°C); RθJA = 22°C/W; MSL Level 1 confirmed | Nearly identical electrical specs; slightly higher thermal resistance limits power density in dense layouts | Drop-in alternative if board space and solder profile match; verify cathode marking orientation |
Compared with VS-8EWH10FN-M3/45 and SB8100E, the SK810CHR7G offers superior high-temperature reverse leakage (10 mA @ 100 V, 100°C vs. 1.0 mA @ 125°C for Vishay), tighter VF consistency across production lots, and documented halogen-free compliance per IEC 61249-2-21.

FAQ
What is the maximum junction temperature rating for SK810CHR7G?
The SK810CHR7G has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings table. This allows uninterrupted operation in enclosed industrial enclosures up to 70°C ambient when mounted on a 1-in² 2-oz copper pad. The SK810CHR7G maintains rated IF up to 110°C case temperature before linear derating begins.
Does SK810CHR7G meet RoHS and halogen-free requirements?
Yes, the SK810CHR7G is RoHS compliant per EU Directive 2011/65/EU 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. Certificate of Compliance is available upon request for SK810CHR7G.
What is the forward voltage of SK810CHR7G at 8 A and 100°C junction temperature?
The SK810CHR7G forward voltage increases with temperature: typical VF is 0.90 V at 25°C, rising to approximately 0.78 V at 100°C (based on Fig.4 characteristic curve interpolation). This negative temperature coefficient improves current sharing in parallel configurations and reduces thermal runaway risk in SK810CHR7G designs.
Is SK810CHR7G suitable for automated SMT assembly without baking?
Yes, SK810CHR7G is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30°C/60% RH and requires no dry-pack or pre-reflow baking. It is fully compatible with standard lead-free reflow profiles (peak 260°C, 60 s above 217°C), making SK810CHR7G ideal for high-throughput automated placement lines.
What does the "R7G" suffix indicate in SK810CHR7G?
The "R7G" suffix in SK810CHR7G denotes tape-and-reel packaging (R7 = 3,000 pcs/reel) and green compound (G), confirming halogen-free epoxy and RoHS compliance. This ordering code aligns with Taiwan Semiconductor's standard DO-214AB packing specification and is distinct from bulk or ammo-pack variants of the SK810C family.
