Product details
Overview
SK510CHR7G from Taiwan Semiconductor is a 5A, 100V Schottky barrier surface-mount rectifier in DO-214AB (SMC) package, qualified to AEC-Q101, with 0.85V forward voltage at 5A and 0.3mA reverse leakage at 25°C, designed for automotive-grade freewheeling and reverse battery protection circuits.
For engineers reviewing the SK510CHR7G datasheet, SK510CHR7G pinout, SK510CHR7G application, or SK510CHR7G equivalent, key selection factors include its 100V VRRM, 120A IFSM, AEC-Q101 qualification, low VF for high-efficiency DC/DC conversion, and DO-214AB thermal performance (RθJL = 13°C/W).
Technical Context
This Schottky rectifier uses a single-die construction with guard ring overvoltage protection and matte tin-plated leads compliant with J-STD-002 solderability. Its junction temperature range of –55°C to +150°C and moisture sensitivity level 1 support reflow-compatible automated assembly in harsh environments.
The device delivers high surge current capability (120A, 8.3ms half-sine) and fast switching with dV/dt rating of 10,000 V/µs. Thermal resistance values - RθJA = 53°C/W, RθJC = 16°C/W - are measured on a 16mm × 16mm Cu pad PCB per JEDEC test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive peak reverse voltage; defines safe blocking capability in 12–48V automotive systems. |
| IF | 5 A - Continuous forward current rating; supports sustained operation in compact DC/DC converters without forced cooling. |
| VF @ 5A, 25°C | 0.85 V - Low forward drop reduces conduction loss and improves system efficiency in high-current paths. |
| IR @ 100V, 25°C | 0.3 mA - Ultra-low reverse leakage enables reliable reverse-battery protection and low standby power loss. |
| IFSM | 120 A - Peak non-repetitive surge current; withstands load dump transients and motor commutation spikes. |
| TJ max | +150 °C - Extended junction temperature rating allows operation in under-hood automotive environments. |
| RθJL | 13 °C/W - Low junction-to-lead thermal resistance enables effective heat transfer to PCB copper pour or heatsink tab. |

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-50WQ10FNTR-M3 | Same 100V VRRM, 5A IF, but TO-220AC package (not SMC); higher RθJA (65°C/W) and no AEC-Q101 rating. | Requires heatsink mounting; unsuitable for space-constrained automotive PCBs. | Select only if through-hole assembly or legacy thermal management infrastructure exists. |
| ON Semiconductor SB5100-E3/54 | DO-214AA (SMB) package, 100V, 5A, but 0.92V VF and 0.5mA IR; not AEC-Q101 qualified. | Larger footprint than DO-214AB; higher conduction loss and leakage reduce efficiency in battery-sensitive designs. | Acceptable for cost-sensitive industrial supplies where AEC-Q101 and ultra-low leakage are not required. |
Compared with VS-50WQ10FNTR-M3 and SB5100-E3/54, SK510CHR7G uniquely combines AEC-Q101 qualification, DO-214AB footprint, 0.85V forward voltage, and 0.3mA reverse leakage - making it the preferred choice for automotive front-end power stages requiring reliability, compactness, and low-loss operation.

FAQ
What is the maximum junction temperature rating for SK510CHR7G?
The SK510CHR7G 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 and high-ambient industrial enclosures. The device maintains specified electrical parameters up to this limit when thermal design adheres to RθJL = 13°C/W on a 16 mm × 16 mm copper pad.
Is SK510CHR7G suitable for use in AEC-Q101-compliant automotive designs?
Yes, SK510CHR7G is explicitly qualified to AEC-Q101 Rev D for stress testing including HTGB, HTRB, TCT, and ESD. The qualification applies to the exact SK510CHR7G marking and DO-214AB package configuration. This makes SK510CHR7G appropriate for safety-critical automotive subsystems such as body control modules, lighting drivers, and infotainment power supplies.
What is the forward voltage of SK510CHR7G at rated current and temperature?
The forward voltage (VF) of SK510CHR7G is 0.85 V at IF = 5 A and TJ = 25°C, as confirmed in the Electrical Specifications table of the Taiwan Semiconductor datasheet. At 125°C junction temperature, VF decreases slightly due to Schottky physics, remaining below 0.78 V - supporting stable performance across automotive thermal profiles.
Does SK510CHR7G have a defined moisture sensitivity level (MSL)?
Yes, SK510CHR7G is rated MSL Level 1 per J-STD-020, meaning it can be stored indefinitely at ≤30°C/85% RH and subjected to standard lead-free reflow profiles (peak 260°C) without baking. This eliminates pre-reflow dry storage requirements and simplifies SMT line integration for high-volume automotive manufacturing.
What packaging and reel quantity is offered for SK510CHR7G?
SK510CHR7G is supplied in DO-214AB (SMC) package on tape-and-reel format, with 3,000 units per reel. The reel complies with EIA-481-D standards and includes green compound molding and standard cathode-band polarity marking. Reel dimensions and orientation follow Taiwan Semiconductor's ordering code SK510CHR7G specification.
