Product details
Overview
SF23GHB0G from Taiwan Semiconductor is a 150 V, 2 A 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 high-frequency switching power supplies.
For engineers reviewing the SF23GHB0G datasheet, SF23GHB0G pinout, SF23GHB0G application, or SF23GHB0G equivalent, key selection criteria include peak repetitive reverse voltage (VRRM = 150 V), surge current capability (IFSM = 50 A), thermal resistance (RθJA = 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 DC/DC conversion. Its 35 ns trr and low VF enable reduced switching losses in 100–500 kHz SMPS topologies.
The DO-204AC package provides mechanical robustness and thermal performance with RθJC = 16 °C/W, supporting continuous 2 A conduction at up to 150 °C junction temperature under proper PCB copper area design.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R015 | VRRM = 150 V, VF = 0.95 V, trr = 30 ns, same DO-15 package but not AEC-Q101 qualified | Suitable for industrial/commercial SMPS but not automotive qualified systems | Select when AEC-Q101 is not required and slightly faster trr is prioritized |
| ON Semi MUR220 | VRRM = 200 V, VF = 0.93 V, trr = 35 ns, DO-15, no AEC-Q101 certification | Higher VRRM margin supports 24 V input systems with line transients; lacks automotive qualification | Choose for 24 V nominal systems needing headroom above 150 V, with no automotive compliance mandate |
Compared with STTH2R015 and MUR220, the SF23GHB0G uniquely combines AEC-Q101 qualification, 150 V rating, and 35 ns trr in DO-15-making it the only option among the three validated for automotive power conversion where reliability under thermal cycling and vibration is mandatory.

FAQ
What is the peak repetitive reverse voltage rating for SF23GHB0G?
The SF23GHB0G has a peak repetitive reverse voltage (VRRM) rating of 150 V, verified per Taiwan Semiconductor's H2105 datasheet. This value defines the maximum reverse-biased voltage the device can block repeatedly without avalanche breakdown. It is critical for selecting appropriate derating margins in 12 V or 24 V automotive and industrial power systems where line transients may exceed nominal bus voltage.
Is SF23GHB0G suitable for automotive applications?
Yes, SF23GHB0G is AEC-Q101 qualified, as confirmed by its "H" suffix in the ordering code and explicit listing in Taiwan Semiconductor's qualification documentation. This means SF23GHB0G has passed stress tests including HTSL, TC, UHAST, and mechanical shock-making it suitable for under-hood and chassis-mounted automotive power modules where reliability under thermal cycling and vibration is mandatory.
What is the forward voltage drop of SF23GHB0G at 2 A and 25 °C?
The forward voltage (VF) of SF23GHB0G is 0.95 V at IF = 2 A and TJ = 25 °C, per the Electrical Specifications table in the H2105 datasheet. This value is measured under pulsed conditions (PW = 0.3 ms) to minimize self-heating. At elevated junction temperatures (e.g., 125 °C), VF decreases slightly due to semiconductor physics, but system-level thermal design must ensure TJ remains ≤150 °C.
Does SF23GHB0G have a defined reverse recovery time?
Yes, SF23GHB0G has a maximum reverse recovery time (trr) of 35 ns, tested at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is critical for minimizing switching losses in high-frequency converters (≥100 kHz). The 35 ns trr enables efficient operation in quasi-resonant and active-clamp flyback topologies where fast diode turn-off reduces voltage spikes and EMI generation.
What package type does SF23GHB0G use and what are its key mechanical features?
SF23GHB0G uses the DO-204AC (DO-15) axial-leaded package. Key mechanical features include glass passivation for junction protection, pure tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 molding compound, and cathode polarity marked by a visible band. Its weight is approximately 0.400 g, and it meets JESD 201 Class 2 whisker resistance for long-term interconnect reliability.
