Product details
Overview
SF2003G from Taiwan Semiconductor is a 20A, 150V super fast recovery rectifier diode in TO-220AB package, featuring 35ns reverse recovery time, 0.975V forward voltage at 10A/25°C, and 150A surge current capability; used in freewheeling paths of DC-DC converters and switching inverters.
For engineers reviewing the SF2003G datasheet, SF2003G pinout, SF2003G application, or SF2003G equivalent, key selection criteria include VRRM = 150V, IF = 20A, trr = 35ns, thermal resistance RθJC = 2.5°C/W, and AEC-Q101 qualification availability (SF2003GH variant).
Technical Context
The SF2003G employs dual-die construction in a single TO-220AB case, enabling high-current handling with low conduction loss. Its super fast recovery (trr ≤ 35ns) minimizes switching losses in high-frequency SMPS topologies operating up to several hundred kHz.
Thermal performance is defined by RθJC = 2.5°C/W, supporting continuous 20A operation with proper heatsinking. The device operates across -55°C to +150°C junction temperature range and meets JESD201 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 |
|---|---|---|---|
| STTH2003D | VRRM = 150V, trr = 30ns, VF = 0.95V @ 10A - Slightly faster but same voltage/current ratings | Optimized for ultra-high-frequency PFC stages; lower leakage (IR = 2µA @ 25°C) | Preferred where <30ns trr is critical and lower leakage reduces standby loss |
| ON Semi MUR2015CT | Dual common-cathode TO-220 package, VRRM = 150V, trr = 35ns, VF = 0.98V @ 10A - Identical recovery and forward specs, but dual common-cathode pinout | Requires PCB layout change due to different terminal assignment (anode-anode-cathode vs. anode-cathode-tab) | Select when dual common-cathode topology is required; verify pin compatibility before layout reuse |
Compared with STTH2003D and MUR2015CT, the SF2003G offers identical 150V/20A/35ns performance in a standard anode-cathode-tab configuration, with optional AEC-Q101 qualification and broader industrial temperature support (–55°C to +150°C).

FAQ
What is the maximum junction temperature rating for SF2003G?
The SF2003G has a maximum junction temperature (TJMAX) of +150°C, with a full operating range from –55°C to +150°C. This rating allows reliable operation in thermally demanding environments such as enclosed power supplies and motor drive modules. Derating curves in the datasheet specify allowable forward current versus case temperature, and thermal design must maintain TJ ≤ 150°C under worst-case load and ambient conditions. The SF2003G achieves this with RθJC = 2.5°C/W.
Is SF2003G pin-compatible with other TO-220AB rectifiers like MUR2015CT?
No, SF2003G is not pin-compatible with MUR2015CT. While both use TO-220AB packages, SF2003G uses anode–cathode–tab (isolated cathode tab) pinout, whereas MUR2015CT uses dual-anode common-cathode configuration. Interchanging them requires PCB layout revision. Always verify terminal assignment using the official marking diagram and mechanical drawings before substitution. The SF2003G datasheet confirms its pinout as Lead 1 = Anode, Lead 2 = Cathode, Tab = Cathode.
Does SF2003G meet automotive reliability standards?
The base SF2003G is not AEC-Q101 qualified, but the variant SF2003GH is explicitly qualified to AEC-Q101. The GH suffix indicates automotive-grade screening, including stress testing for temperature cycling, humidity, and mechanical shock. For automotive applications such as on-board chargers or DC-DC converters in ADAS subsystems, SF2003GH must be specified. The SF2003G remains suitable for industrial and computing applications where AEC-Q101 is not mandated.
What is the reverse recovery time (trr) test condition for SF2003G?
The SF2003G reverse recovery time is measured at IF = 0.5A, IR = 1.0A, and Irr = 0.25A, per JEDEC standard test methodology. The typical value is 35ns, with no maximum specified in the datasheet. This condition reflects light-load switching behavior relevant to gate-drive and snubber circuits. For heavy-load evaluation, designers should consult the reverse recovery charge (Qrr) curve in the characteristics section, though Qrr is not explicitly tabulated for SF2003G.
How does the dual-die structure of SF2003G impact its use in circuit design?
The SF2003G integrates two independent rectifier dies in one TO-220AB package, sharing only the cathode connection via the metal tab. This enables flexible implementation: either as a single 20A rectifier (using one die), or as two 10A parallel paths (with external current balancing). It is not a dual-common-cathode or dual-common-anode device. Designers must ensure thermal coupling between dies is accounted for in heatsink design, as both contribute to total power dissipation. The SF2003G datasheet confirms "dual dies" under KEY PARAMETERS.
