Product details
Overview
SK510CHM6G from Taiwan Semiconductor is a 5A, 100V AEC-Q101-qualified Schottky barrier rectifier in DO-214AB (SMC) package, featuring 0.85V forward voltage at 5A and 0.3mA reverse leakage at 25°C, optimized for automotive DC/DC converters and reverse battery protection circuits.
For engineers reviewing the SK510CHM6G datasheet, SK510CHM6G pinout, SK510CHM6G application, or SK510CHM6G equivalent, key selection criteria include its 100V repetitive peak reverse voltage, 120A surge capability, junction-to-lead thermal resistance of 13°C/W, and moisture sensitivity level 1 compliance for high-reliability automotive assembly.
Technical Context
This discrete Schottky diode uses a single-die construction with guard ring overvoltage protection and matte tin-plated leads compliant with J-STD-002 solderability. Its 150°C maximum junction temperature and -55°C to +150°C storage range support under-hood automotive environments.
The device delivers low power loss via 0.85V forward voltage at rated 5A current and maintains stable reverse blocking up to 100V VRRM, with 5mA reverse leakage at 125°C - critical for thermally constrained freewheeling and clamping applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; defines safe operating limit in reverse-biased clamping or freewheeling roles. |
| IF | 5 A - Continuous forward current rating; determines steady-state power handling in DC/DC output rectification. |
| VF @ 5A, 25°C | 0.85 V - Low conduction loss enabling high-efficiency operation in 12V–48V automotive power stages. |
| IR @ 100V, 25°C | 0.3 mA - Minimal leakage ensures low standby power in reverse-battery protection and always-on systems. |
| IFSM | 120 A - Peak non-repetitive surge current capacity; withstands load dump transients in automotive electrical systems. |
| RθJL | 13 °C/W - Junction-to-lead thermal resistance; enables direct PCB copper pad heat sinking without additional heatsinks. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive-grade reliability including temperature cycling and HTRB. |
Pinout & Package
Package: DO-214AB (SMC), surface-mount plastic case with cathode band polarity marking, 0.210g mass, UL 94V-0 molding compound, and JESD201 Class 2 whisker-resistant matte tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., ground or switch node) in freewheeling or reverse protection configurations. |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; connects to higher-potential rail (e.g., battery input) in reverse-battery protection or DC/DC output. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood use including temperature cycling, HTRB, and ESD testing per JEDEC standards. |
| Guard ring structure | Enhances ruggedness against transient overvoltage events such as load dump without external snubbers. |
| Moisture sensitivity level 1 | Eliminates bake requirements prior to reflow; supports standard SMT assembly without special handling. |
| Halogen-free & RoHS compliant | Meets automotive environmental regulations and end-of-life material restrictions for global vehicle programs. |

Applications
| Automotive DC/DC Converters | Reverse Battery Protection |
|---|---|
Use Scenario: Step-down conversion from 12V/48V battery to 3.3V/5V rails in ADAS ECUs and infotainment modules.

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-50WQ10FN-M3/45 | Same 100V VRRM, 5A IF, but TO-220AC package (not SMC); 0.72V VF at 5A; no AEC-Q101 claim. | Requires through-hole mounting and heatsink; unsuitable for space-constrained automotive SMT designs. | Select only if board layout allows TO-220 footprint and AEC-Q101 is not required. |
| ON Semiconductor SB5100-E3/54 | DO-214AA (SMB) package; 100V VRRM, 5A IF; 0.85V VF; AEC-Q101 qualified; 1.2A lower IFSM (110A). | Smaller footprint but lower surge margin; may require derating in high-transient environments. | Acceptable where board area is critical and load dump energy is moderate. |
Compared with VS-50WQ10FN-M3/45 and SB5100-E3/54, SK510CHM6G uniquely combines AEC-Q101 qualification, DO-214AB SMC packaging, and 120A surge rating - making it optimal for compact, high-reliability automotive power nodes where thermal performance and transient immunity are jointly critical.

FAQ
What is the maximum junction temperature rating for SK510CHM6G?
The SK510CHM6G has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating enables reliable operation in under-hood automotive environments where ambient temperatures exceed 105°C. The device's RθJL of 13°C/W further supports thermal management when mounted on adequate copper pads. SK510CHM6G must be operated within this limit to maintain AEC-Q101 qualification integrity.
Is SK510CHM6G suitable for reverse battery protection in 24V commercial vehicles?
Yes, SK510CHM6G is suitable for reverse battery protection in 24V commercial vehicles due to its 100V VRRM, which exceeds the worst-case reverse voltage (±36V during jump-start or load dump). Its 0.3mA reverse leakage at 25°C and 5mA at 125°C ensures minimal standby current draw. SK510CHM6G's AEC-Q101 qualification and DO-214AB package also meet mechanical and reliability requirements for heavy-duty vehicle electronics.
Does SK510CHM6G have halogen-free and RoHS compliance documentation?
Yes, SK510CHM6G is explicitly documented as halogen-free and RoHS compliant in Taiwan Semiconductor's official datasheet (Version C2311). The molding compound meets UL 94V-0, and terminal plating satisfies J-STD-002 solderability requirements. These certifications are confirmed in the "Features" section and ordering information table. SK510CHM6G carries the "G" suffix per TSC's marking convention for green-compliant devices.
What is the surge current rating of SK510CHM6G and how is it tested?
The SK510CHM6G has a peak non-repetitive forward surge current (IFSM) rating of 120A, tested using an 8.3ms single half-sine wave superimposed on rated load per JEDEC standards. This value is specified in the Absolute Maximum Ratings table and validated across temperature ranges. SK510CHM6G's guard ring design enhances ruggedness during such surges, making it suitable for automotive load dump scenarios without external protection.
How does the forward voltage of SK510CHM6G compare to other 100V Schottky rectifiers in the same family?
SK510CHM6G has a typical forward voltage (VF) of 0.85V at 5A and 25°C - identical to SK59CH and positioned between SK56CH (0.75V) and SK515CH (0.95V) in the SK5xCH family. This reflects the trade-off between reverse voltage rating and conduction loss. SK510CHM6G's VF is confirmed in the Electrical Specifications table and remains stable across its operating temperature range, supporting predictable thermal design in SK510CHM6G-based power stages.
