Product details
Overview
SK56CHR7G from Taiwan Semiconductor is a 5A, 60V Schottky barrier surface-mount rectifier in DO-214AB (SMC) package, AEC-Q101 qualified for automotive use, with 0.75V forward voltage at 5A and 0.5mA reverse current at 25°C. It serves as a freewheeling or reverse-battery protection diode in high-frequency DC/DC converters.
For engineers reviewing the SK56CHR7G datasheet, SK56CHR7G pinout, SK56CHR7G application, or SK56CHR7G equivalent, key selection criteria include its 60V VRRM, 120A IFSM surge rating, 13°C/W junction-to-lead thermal resistance, and DO-214AB mechanical compatibility with automated SMT placement.
Technical Context
The SK56CHR7G employs a single-die Schottky structure optimized for low forward voltage drop and fast switching, enabling high-efficiency operation in low-voltage, high-frequency power conversion stages. Its guard ring design enhances overvoltage robustness, and moisture sensitivity level 1 ensures reliability in standard reflow processes.
Thermal performance is characterized by RθJL = 13°C/W and RθJA = 53°C/W on a 16mm × 16mm Cu pad PCB, supporting continuous 5A conduction up to 150°C junction temperature. The device meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements.

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-50SQ060NTRP | Same 60V VRRM, 5A IF, but TO-277 package (smaller footprint); VF = 0.72V @ 5A. | Higher power density; less PCB copper area required, but lower IFSM (80A vs. 120A). | Prefer for space-constrained modules where surge margin is secondary to board area. |
| ON Semiconductor SB560-E3/54 | DO-214AA (SMB) package; same 60V/5A rating, but VF = 0.78V @ 5A and IR = 0.6mA @ 25°C. | Lower thermal mass and RθJA = 65°C/W; suitable for lower-power or intermittent-duty use. | Choose when cost sensitivity outweighs thermal performance needs in consumer-grade 48V systems. |
Compared with SK56CHR7G, the VS-50SQ060NTRP offers tighter VF and smaller footprint but reduced surge capability, while the SB560-E3/54 trades thermal robustness for lower cost and SMB compatibility-neither is pin-compatible, requiring layout revision.

FAQ
What is the maximum junction temperature rating for SK56CHR7G?
The SK56CHR7G has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This allows uninterrupted 5A operation in under-hood automotive environments when mounted on a 16mm × 16mm copper pad, and supports thermal design margins up to 150°C without derating. The SK56CHR7G's RθJL of 13°C/W further enables efficient heat transfer to the PCB.
Is SK56CHR7G suitable for reverse battery protection in 12V automotive systems?
Yes, SK56CHR7G is explicitly validated for reverse battery protection in 12V automotive systems. Its 60V VRRM provides 2× margin over nominal 12V bus, 0.5mA IR at 25°C minimizes standby current draw, and AEC-Q101 qualification confirms reliability under automotive temperature cycling and vibration. The SK56CHR7G's cathode band marking ensures correct orientation during automated assembly.
Does SK56CHR7G have halogen-free and RoHS-compliant construction?
Yes, SK56CHR7G is both halogen-free and RoHS compliant, as confirmed in the "Features" section of the Taiwan Semiconductor datasheet (Version C2311). The molding compound meets UL 94V-0, and terminals are matte tin-plated per J-STD-002. These attributes satisfy IPC-1752A material declarations and EU Directive 2011/65/EU requirements for environmentally conscious electronics manufacturing using SK56CHR7G.
What is the surge current rating of SK56CHR7G and how is it tested?
The SK56CHR7G has a peak non-repetitive forward surge current (IFSM) rating of 120A, tested per JEDEC standards using an 8.3ms single half-sine waveform superimposed on rated load. This rating is validated across the full operating temperature range and enables the SK56CHR7G to survive load dump transients and motor startup surges common in automotive and industrial 48V systems without degradation.
What package type does SK56CHR7G use and what are its key mechanical features?
SK56CHR7G uses the DO-214AB (SMC) surface-mount package, with dimensions per JEDEC DO-214 Variation AB. Key mechanical features include a 0.210g weight, matte tin-plated leads solderable per J-STD-002, polarity indicated by cathode band, and UL 94V-0 flammability-rated molding compound. The SK56CHR7G's pad layout recommendation supports reliable reflow attachment on standard PCBs.
