Product details
Overview
SF23G R0G from Taiwan Semiconductor is a 2 A, 150 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 50 A surge current capability. It serves as a freewheeling or output rectifier in high-frequency DC-DC converters and switching inverters.
For engineers reviewing the SF23G R0G datasheet, SF23G R0G pinout, SF23G R0G application, or SF23G R0G equivalent, key selection criteria include repetitive peak reverse voltage (150 V), junction-to-ambient thermal resistance (65 °C/W), reverse recovery time (35 ns), forward voltage (0.95 V), and AEC-Q101 qualification status.
Technical Context
The SF23G R0G employs a glass-passivated silicon junction optimized for fast switching in high-efficiency power conversion topologies. Its 35 ns trr and low VF enable reduced switching losses in 100–500 kHz SMPS designs.
Rated for TJ = –55 °C to +150 °C and qualified per AEC-Q101, it supports automotive-grade reliability in thermally demanding environments. The DO-204AC package provides 16 °C/W junction-to-case thermal resistance and meets UL 94V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse blocking voltage; defines safe operating range in flyback or boost output stages |
| IF | 2 A - Continuous average forward current; sets steady-state power handling without derating below 75 °C ambient |
| IFSM | 50 A - Non-repetitive surge rating; withstands inrush or fault currents in 8.3 ms half-sine events |
| trr | 35 ns - Reverse recovery time; enables efficient operation up to ~500 kHz with minimal switching loss |
| VF @ 2 A | 0.95 V - Forward voltage drop at rated current; determines conduction loss (1.9 W at 2 A) |
| CJ @ 4 V | 40 pF - Junction capacitance at 4 V reverse bias; impacts high-frequency EMI and snubber design |
| RθJA | 65 °C/W - Thermal resistance from junction to ambient; requires ≥1.2 cm² copper pad for full 2 A rating at 75 °C |
Pinout & Package
DO-204AC (DO-15) axial-leaded package with cathode band marking. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.

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 | Same VRRM (150 V), IF (2 A), but trr = 25 ns; VF = 0.92 V; TO-220AC package | Higher thermal mass enables higher continuous current in heatsinked designs; not axial-leaded | Select when board space allows TO-220 and higher thermal margin is needed |
| ON Semi MUR220 | VRRM = 200 V, IF = 2 A, trr = 35 ns, VF = 0.93 V; same DO-204AC package | Higher voltage rating suits 24 V systems with elevated transients; identical footprint | Choose for designs requiring >150 V margin without layout change |
Compared with STTH2R015 and MUR220, the SF23G R0G offers optimal balance of axial-leaded manufacturability, AEC-Q101 readiness, and 150 V/2 A/35 ns performance-making it preferred for cost-sensitive, high-volume automotive and industrial through-hole power supplies where leaded assembly and qualification are mandatory.

FAQ
What is the maximum junction temperature rating for SF23G R0G?
The SF23G R0G has a maximum junction temperature (TJ MAX) of +150 °C, validated over the full operating range from –55 °C to +150 °C. This rating enables reliable operation in under-hood automotive environments and enclosed industrial enclosures. Derating begins above 75 °C ambient per the forward current derating curve in the datasheet. The SF23G R0G must be mounted on adequate copper area to maintain junction temperature within limit at full 2 A load.
Is SF23G R0G AEC-Q101 qualified?
The base SF23G R0G part is not AEC-Q101 qualified; however, the AEC-Q101 variant is designated SF23GH (with 'H' suffix). The R0G suffix indicates green compound and standard industrial qualification. For automotive applications requiring AEC-Q101 compliance, SF23GH must be specified. Both share identical electrical parameters and DO-204AC packaging, but only SF23GH undergoes the full stress test sequence per AEC-Q101 Rev D.
What is the reverse recovery time (trr) of SF23G R0G and how is it measured?
The SF23G R0G has a maximum reverse recovery time (trr) of 35 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A using the test circuit defined in Figure 6 of the datasheet. This value reflects the time required for minority carriers to clear after forward conduction ceases, directly impacting switching loss in high-frequency topologies. The SF23G R0G achieves this performance via optimized doping and lifetime control in its glass-passivated silicon die.
What does the 'R0G' suffix mean in SF23G R0G?
The 'R0G' suffix in SF23G R0G denotes Taiwan Semiconductor's internal packaging and environmental coding: 'R0' specifies tape-and-reel packaging with 3,500 units per reel, and 'G' indicates halogen-free, RoHS-compliant green molding compound meeting IEC 61249-2-21. It is not a functional variant-electrical and thermal specs match the base SF23G. The SF23G R0G is functionally identical to SF23G but supplied in standardized reel format for SMT-compatible through-hole placement.
Can SF23G R0G replace SF22G or SF24G in an existing design?
Yes, the SF23G R0G can directly replace SF22G (100 V) or SF24G (200 V) in most cases, provided the system's peak reverse voltage remains within 150 V. All SFxG devices share identical IF (2 A), IFSM (50 A), trr (35 ns), VF (0.95 V), and DO-204AC packaging. The only difference is VRRM: SF22G = 100 V, SF23G R0G = 150 V, SF24G = 200 V. Substituting SF23G R0G for SF24G reduces voltage margin; substituting for SF22G improves it. No PCB or layout changes are needed.
