Product details
Overview
SK36BHR5G from Taiwan Semiconductor is a 60 V, 3 A surface-mount Schottky barrier rectifier in DO-214AA (SMB) package, featuring low forward voltage (0.85 V at 3 A, 25°C), high surge current capability (70 A), and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or reverse-battery protection diode in DC/DC converters and car lighting systems.
For engineers reviewing the SK36BHR5G datasheet, SK36BHR5G pinout, SK36BHR5G application, or SK36BHR5G equivalent, key selection criteria include its 60 V repetitive peak reverse voltage, 0.85 V forward drop at rated current, 2 mA reverse leakage at 125°C, junction-to-lead thermal resistance of 23°C/W, and DO-214AA mechanical compatibility with automated SMT assembly.
Technical Context
The SK36BHR5G implements a single-die Schottky junction optimized for low-loss unidirectional conduction in medium-voltage power conversion stages. Its guard ring structure enhances overvoltage robustness, while the matte tin-plated leads ensure solderability per J-STD-002 and whisker resistance per JESD 201 Class 2.
Designed for operation up to 150°C junction temperature, it delivers stable performance under transient surge conditions (8.3 ms half-sine, 70 A) and maintains low dV/dt sensitivity (10,000 V/μs), supporting reliable switching in high-frequency DC/DC topologies without parasitic turn-on.

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-3EYH06-M3/54 | Same 60 V VRRM, 3 A IF, but VF = 0.72 V typ at 3 A; DO-214AC (SMA) package, smaller footprint and higher RθJA. | Better efficiency at light loads; unsuitable for high-temperature ambient due to 125°C TJ max and higher thermal resistance. | Select when board space is constrained and ambient temperature remains below 85°C. |
| ON Semiconductor SB360-E3/54 | 60 V VRRM, 3 A IF, VF = 0.74 V typ; DO-214AA package; not AEC-Q101 qualified; IR = 500 µA at 25°C (vs. SK36BHR5G's 100 µA). | Lacks automotive qualification; higher room-temp leakage may impact battery-drain-sensitive designs. | Select for cost-sensitive industrial or consumer applications where AEC-Q101 is not mandated. |
Compared with VS-3EYH06-M3/54 and SB360-E3/54, the SK36BHR5G offers superior high-temperature leakage control (2 mA at 125°C), extended 150°C junction rating, and AEC-Q101 validation-making it the preferred choice for under-hood automotive and thermally demanding industrial power rails.

FAQ
What is the maximum junction temperature rating for the SK36BHR5G?
The SK36BHR5G has a maximum junction temperature (TJ) rating of +150°C, verified per AEC-Q101 stress testing. This allows uninterrupted operation in under-hood automotive environments and enclosed industrial power supplies where ambient temperatures reach 105°C, provided thermal design meets the 23°C/W junction-to-lead resistance specification. The SK36BHR5G maintains stable forward voltage and leakage characteristics across this full range.
Is the SK36BHR5G suitable for reverse battery protection in 12 V automotive systems?
Yes, the SK36BHR5G is specifically designed for reverse battery protection in 12 V automotive systems. Its 60 V VRRM provides ample margin against load-dump transients (up to ISO 7637-2 Pulse 5a), and its AEC-Q101 qualification confirms reliability under automotive thermal cycling, vibration, and humidity stress. The cathode band clearly indicates polarity, and the 0.85 V forward drop minimizes voltage loss in the protection path.
What packaging and reel quantity does the SK36BHR5G ship in?
The SK36BHR5G ships in DO-214AA (SMB) package on 3,000-piece tape-and-reel format, compatible with standard SMT pick-and-place equipment. The reel complies with EIA-481-D standards, and the device marking "SK36B" is laser-etched on the cathode end per TSC's ordering code convention. Moisture sensitivity level is rated at Level 1 (J-STD-020), eliminating bake requirements prior to reflow.
How does the SK36BHR5G's forward voltage compare to similar 60 V Schottky rectifiers?
The SK36BHR5G specifies a maximum forward voltage of 0.85 V at 3 A and 25°C - competitive with industry-standard 60 V Schottky rectifiers such as SB360-E3/54 (0.74 V typ) and slightly higher than VS-3EYH06-M3/54 (0.72 V typ). However, its 0.85 V value is measured under standardized pulse conditions (PW = 0.3 ms), and its real-world conduction loss remains low due to stable VF temperature coefficient and low RθJL enabling efficient heat transfer.
Does the SK36BHR5G have halogen-free and RoHS-compliant construction?
Yes, the SK36BHR5G uses halogen-free molding compound per IEC 61249-2-21 and is fully RoHS compliant (2011/65/EU). All plating, die attach, and encapsulation materials meet strict environmental regulations for global electronics manufacturing. The "G" suffix in SK36BHR5G explicitly denotes green compound compliance, and material declarations are available upon request for OEM documentation and audit purposes.
