Product details
Overview
SF22GHB0G from Taiwan Semiconductor is a 2 A, 100 V super fast recovery rectifier diode in DO-204AC (DO-15) package, featuring 35 ns reverse recovery time, 0.95 V forward voltage at 2 A, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or output rectifier in DC-DC converters and switching-mode power supplies.
For engineers reviewing the SF22GHB0G datasheet, SF22GHB0G pinout, SF22GHB0G application, or SF22GHB0G equivalent, key selection criteria include repetitive peak reverse voltage (100 V), surge current capability (50 A), thermal resistance (65 °C/W), junction temperature range (–55 to +150 °C), and RoHS/halogen-free compliance.
Technical Context
This device is a single-die, glass-passivated silicon PN junction rectifier optimized for high-efficiency switching applications. Its 35 ns trr and low VF enable reduced switching losses in high-frequency converters operating up to several hundred kHz.
The DO-204AC package provides mechanical robustness and thermal performance with RθJA = 65 °C/W and RθJC = 16 °C/W. Cathode polarity is marked by a band; terminals are pure tin-plated for J-STD-002 solderability.
Key Specifications

| VRRM | 100 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in flyback or buck output stages |
| IF | 2 A - Continuous average forward current; sets steady-state power delivery capacity |
| IFSM | 50 A - Non-repetitive surge rating; supports inrush and transient overload without failure |
| trr | 35 ns - Reverse recovery time; enables efficient operation in 100–500 kHz SMPS topologies |
| VF | 0.95 V @ 2 A, 25°C - Low conduction loss; reduces heat generation and improves system efficiency |
| RθJA | 65 °C/W - Junction-to-ambient thermal resistance; determines required heatsinking for ambient temperatures up to 75°C |
| Junction Temp | –55 to +150°C - Extended operating range suitable for under-hood automotive environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R010DJF | 100 V, 2 A, 30 ns trr, TO-277A flatpack; slightly faster but higher VF (1.05 V) | Surface-mount alternative requiring PCB rework; better for ultra-high-frequency designs (>300 kHz) | Select when board space is constrained and SMT assembly is preferred over axial leads. |
| ON Semiconductor MUR210E | 100 V, 2 A, 50 ns trr, DO-41; slower recovery, same package footprint but lower surge rating (30 A) | Lower-cost option for <200 kHz applications where efficiency margin is less critical | Choose for cost-sensitive consumer power supplies where 35 ns trr advantage is not required. |
Compared with STTH2R010DJF and MUR210E, SF22GHB0G delivers optimal balance of speed (35 ns), conduction loss (0.95 V), and automotive qualification in a standard through-hole package-making it ideal for medium-frequency, reliability-critical designs where layout change is not feasible.

FAQ
What is the maximum junction temperature rating for SF22GHB0G?
The SF22GHB0G has a maximum junction temperature (TJ) of +150°C, validated across its full operating range from –55°C to +150°C. This rating supports deployment in under-hood automotive environments and sealed industrial enclosures. Thermal derating begins above 25°C ambient, with full 2 A current rated up to 75°C ambient when mounted on standard FR-4 PCB with 1-inch² copper pour.
Is SF22GHB0G pin-compatible with other DO-204AC rectifiers like 1N4007?
No-SF22GHB0G is not functionally or electrically interchangeable with general-purpose rectifiers such as 1N4007. While both use DO-204AC (DO-15) packaging, SF22GHB0G is a super fast rectifier (35 ns trr, 100 V VRRM, 0.95 V VF), whereas 1N4007 is a slow general-purpose device (30 µs trr, 1000 V VRRM, 1.1 V VF). Substitution requires circuit-level validation.
Does SF22GHB0G meet automotive qualification standards?
Yes-SF22GHB0G is explicitly AEC-Q101 qualified, as confirmed by the "H" suffix in its ordering code and documentation in Taiwan Semiconductor's SF2xG datasheet (Version H2105). This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and high-temperature reverse bias-ensuring suitability for automotive power electronics.
What does the "B0G" suffix indicate in SF22GHB0G?
The "B0G" suffix in SF22GHB0G denotes tape-and-reel packaging: "B" indicates green compound (halogen-free), "0" is a placeholder, and "G" confirms RoHS-compliant plating. The base part SF22GH already signals AEC-Q101 qualification ("H"), and "B0G" specifies the DO-204AC package supplied in 3,500-unit reels per the ordering table.
How does SF22GHB0G's thermal resistance affect PCB layout?
SF22GHB0G has RθJA = 65 °C/W and RθJC = 16 °C/W. To maintain TJ ≤ 125°C at 2 A continuous load, ambient must stay ≤ 65°C with standard FR-4 and ≥ 0.5-inch² copper pour on both sides. Increasing copper area or adding thermal vias under the cathode/anode pads directly lowers effective RθJA; no external heatsink is needed below 1.5 A in typical layouts.
