Product details
Overview
SF63GHR0G from Taiwan Semiconductor is a 150 V, 6 A super fast recovery rectifier diode in DO-201AD package, featuring 35 ns reverse recovery time, 0.975 V forward voltage at 6 A/25°C, and 150 A surge capability - deployed in DC-DC converters and switching-mode inverters for high-efficiency power conversion.
For engineers reviewing the SF63GHR0G datasheet, SF63GHR0G pinout, SF63GHR0G application, or SF63GHR0G equivalent, key selection criteria include repetitive peak reverse voltage (150 V), thermal resistance (5 °C/W junction-to-lead), junction capacitance (100 pF), AEC-Q101 qualification status, and DO-201AD mechanical compatibility with standard through-hole reflow or wave soldering processes.
Technical Context
This super fast rectifier uses a single-die silicon PN junction optimized for low conduction loss and rapid carrier recombination. Its 35 ns trr enables operation in high-frequency switching topologies up to several hundred kHz without excessive switching loss or voltage overshoot.
The device operates across –55°C to +150°C junction temperature range, with 5 °C/W RθJL enabling direct heat transfer to PCB copper or heatsink via lead frame, and supports 8.3 ms half-sine surge current up to 150 A - critical for handling inrush and transient overloads in industrial SMPS designs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH6L06D | 6 A / 600 V, 50 ns trr, TO-220AC package, higher VF (1.15 V) | Higher voltage rating but slower recovery and larger footprint; requires heatsink above 3 A | Prefer when >300 V blocking is required and board space permits TO-220 mounting |
| ES1J-E3/57T | 1 A / 600 V, 35 ns trr, DO-214AA (SMA), lower IF and IFSM | Not suitable for 6 A continuous use; limited to <2 A average current in same thermal environment | Select only for low-power auxiliary rails where 6 A rating is unnecessary and surface-mount is mandatory |
Compared with STTH6L06D and ES1J-E3/57T, SF63GHR0G uniquely balances 6 A current, 150 V rating, 35 ns speed, and DO-201AD through-hole compatibility - making it optimal for cost-sensitive, medium-power industrial and automotive DC-DC stages where thermal and layout constraints exclude TO-220 or SMA solutions.

FAQ
What is the peak repetitive reverse voltage rating of SF63GHR0G?
The SF63GHR0G has a repetitive peak reverse voltage (VRRM) rating of 150 V. This value is specified per the official Taiwan Semiconductor datasheet Version G2105 and defines the maximum allowable reverse-biased voltage the device can block repeatedly without breakdown. It ensures reliable operation in 48 V nominal systems with 2× safety margin against transient overvoltage events.
Is SF63GHR0G AEC-Q101 qualified?
Yes, SF63GHR0G is AEC-Q101 qualified. The "HR0G" suffix explicitly denotes AEC-Q101 stress-tested and automotive-grade reliability validation, including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge testing. This makes SF63GHR0G suitable for automotive body electronics, ADAS power supplies, and other under-hood applications requiring certified reliability.
What is the forward voltage drop of SF63GHR0G at rated current?
The forward voltage (VF) of SF63GHR0G is 0.975 V at 6 A and 25°C junction temperature, as measured under pulsed conditions (PW = 0.3 ms). This low VF directly reduces conduction losses in power stages - for example, yielding ~0.6 W less dissipation than a 1.1 V alternative at full load - improving thermal performance and overall system efficiency.
What package type does SF63GHR0G use, and what are its key mechanical features?
SF63GHR0G uses the DO-201AD axial-leaded package: 9.5 mm body length, 3.6 mm diameter, 0.76 mm lead diameter, with cathode polarity indicated by a band. Its molding compound meets UL 94V-0 flammability, leads are pure tin-plated per J-STD-002, and it passes JESD201 Class 2 whisker testing - ensuring robust solderability and long-term mechanical reliability in industrial and automotive assemblies.
How does the 35 ns reverse recovery time of SF63GHR0G impact circuit performance?
The 35 ns reverse recovery time (trr) of SF63GHR0G minimizes reverse recovery charge (Qrr) and associated switching losses in hard-switched topologies. In practice, this enables stable operation up to ~300 kHz in DC-DC converters without snubbers, reduces voltage overshoot across switching FETs, and lowers EMI generation - especially critical in compact, high-density power supplies where thermal and filtering margins are constrained.
