Product details
Overview
SF2003G from Taiwan Semiconductor is a 150V, 20A 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 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 for enhanced current handling and thermal performance. Its super fast recovery (trr ≤ 35ns) minimizes switching losses in high-frequency SMPS topologies operating up to several hundred kHz.
Designed with low VF (0.975V @ 10A, 25°C) and low junction capacitance (CJ = 80pF @ 4V), the SF2003G supports efficient energy transfer in flyback and forward converter freewheeling legs while maintaining stable reverse leakage (<5µA @ 25°C, <400µA @ 125°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 150V-rated DC bus or clamp circuits. |
| IF | 20 A - Continuous average forward current; supports sustained conduction in high-power secondary-side rectification. |
| trr | 35 ns - Reverse recovery time; enables operation in >200 kHz switching converters with minimal commutation loss. |
| VF | 0.975 V @ 10A, 25°C - Low forward drop reduces conduction loss and improves system efficiency at rated load. |
| RθJC | 2.5 °C/W - Junction-to-case thermal resistance; allows direct heatsink mounting for thermal management in industrial power supplies. |
| IFSM | 150 A - Non-repetitive surge current (8.3ms half-sine); withstands inrush and fault transients without failure. |
Pinout & Package
TO-220AB package: 3-terminal through-hole outline with isolated tab (cathode-connected tab), matte tin-plated leads, UL 94V-0 molding compound, and 1.82g mass. Mounting torque ≤ 0.56 N·m.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input current entry | Connected to transformer secondary or switch node; carries full forward current during conduction phase. |
| Cathode (Lead 2) | Output current exit | Connected to output capacitor or load return; electrically tied to metal tab for thermal and electrical path. |
| Tab (Cathode) | Thermal & electrical cathode node | Provides primary heat dissipation path to heatsink; must be electrically isolated if circuit requires floating cathode. |
Key Features
| Feature | Design Value |
|---|---|
| Super fast recovery | trr = 35 ns - Reduces switching loss and EMI in high-frequency SMPS designs. |
| Low forward voltage | VF = 0.975 V @ 10A - Lowers conduction loss and thermal stress under continuous load. |
| Dual-die configuration | Single-package 20A rating - Enables compact layout vs. parallel discrete diodes; improves current sharing reliability. |
| AEC-Q101 qualified option | SF2003GH variant available - Meets automotive-grade reliability requirements for under-hood power modules. |

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 = 300V, trr = 30ns, VF = 1.05V @ 10A - higher voltage rating, slightly faster recovery, marginally higher VF | Preferred in 300V bus systems where derating headroom is required; not drop-in due to different marking and thermal pad design | Select when VRRM margin > 2× operating voltage is mandated; verify heatsink interface compatibility. |
| ON Semi MUR2030CT | Dual common-cathode configuration, VRRM = 300V, trr = 35ns, VF = 1.1V @ 10A - same recovery speed but higher VF and asymmetric voltage rating per die | Used in dual-output supplies requiring independent cathode routing; TO-220AC package lacks isolated tab | Choose only when dual-cathode topology is required; note tab is not electrically isolated - requires insulating hardware. |
Compared with STTH2003D and MUR2030CT, the SF2003G offers optimal balance of 150V rating, 0.975V VF, and isolated-tab TO-220AB packaging - making it ideal for cost-sensitive, thermally constrained 150V industrial DC-DC and inverter freewheeling where AEC-Q101 qualification may be added via SF2003GH.

FAQ
What is the maximum junction temperature rating for SF2003G?
The SF2003G has a maximum junction temperature (TJ) of +150°C, with operational range from –55°C to +150°C. This rating supports reliable operation in enclosed industrial power supplies and automotive under-hood environments when mounted on an appropriately sized heatsink with thermal resistance ≤ 2.5°C/W to ambient.
Is SF2003G pin-compatible with other devices in the SF200xG family?
Yes, all SF200xG devices - including SF2001G through SF2008G - share identical TO-220AB mechanical outline, pin assignment, and terminal configuration. Only VRRM, VF, and trr vary by part number; PCB layout and mounting hardware remain unchanged across the family.
Does SF2003G have an automotive-qualified version?
Yes, the SF2003GH variant is AEC-Q101 qualified and marked with "H" suffix. It undergoes additional stress testing for temperature cycling, humidity bias, and mechanical shock - meeting automotive requirements for on-board chargers, DC-DC converters, and body control modules.
What is the reverse leakage current specification for SF2003G at elevated temperature?
At 125°C junction temperature and rated VR, the SF2003G exhibits maximum reverse leakage current (IR) of 400 µA per diode. At 25°C, IR is limited to 5 µA - critical for minimizing standby power loss in always-on power rails.
How does the dual-die structure of SF2003G affect its thermal performance?
The SF2003G integrates two matched dies in one TO-220AB package to achieve 20A rating while maintaining low RθJC of 2.5°C/W. This architecture avoids thermal imbalance issues seen in paralleled discrete diodes and provides uniform current sharing without external balancing components.
