Product details
Overview
SF2004GHC0G from Taiwan Semiconductor is a 20A, 200V super fast rectifier diode in TO-220AB package, featuring 35ns reverse recovery time, 0.975V forward voltage at 10A/25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or output rectifier in high-frequency DC-DC converters.
For engineers reviewing the SF2004GHC0G datasheet, SF2004GHC0G pinout, SF2004GHC0G application, or SF2004GHC0G equivalent, key selection criteria include VRRM = 200V, IF = 20A, trr = 35ns, VF = 0.975V @ 10A, and AEC-Q101 qualification status - all critical for switching power supply design and automotive under-hood deployment.
Technical Context
This device is a single-die, unidirectional super fast recovery rectifier optimized for high-efficiency, high-frequency operation. Its 35ns reverse recovery time and low 0.975V forward voltage minimize conduction and switching losses in hard-switched topologies.
The TO-220AB package provides 2.5°C/W junction-to-case thermal resistance and supports direct heatsink mounting with ≤0.56 N·m torque. It is rated for continuous operation from –55°C to +150°C junction temperature and meets JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage; defines safe blocking capability in 200V-rated DC-DC outputs |
| IF | 20 A - Average forward current rating; supports continuous 20A output rectification at TC ≤ 85°C |
| trr | 35 ns - Reverse recovery time; enables stable operation up to ~500 kHz switching frequencies |
| VF | 0.975 V @ 10A, 25°C - Low conduction loss; reduces power dissipation by ~2W vs. standard FRDs at same current |
| RθJC | 2.5 °C/W - Thermal resistance; allows ~8W power dissipation with 20°C case-to-ambient rise using standard heatsink |
| IFSM | 150 A - Non-repetitive surge rating; withstands inrush and fault currents in SMPS startup or overload |
| AEC-Q101 | Qualified - Validated for automotive applications including engine control, ADAS power rails, and infotainment DC-DC stages |
Pinout & Package
TO-220AB package with 3-terminal configuration: Anode (Pin 1), Cathode (Pin 2), and Case (Pin 3, electrically connected to cathode). Mounting tab is cathode-side, enabling direct heatsink connection without isolation hardware.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Lead) | Anode | Input terminal for forward conduction; connects to switching node or transformer secondary |
| Pin 2 (Lead) | Cathode | Output terminal; ties to output capacitor and load; also electrically bonded to metal tab |
| Tab (Case) | Cathode | Thermal and electrical path to heatsink; requires no insulating washer when heatsink is referenced to cathode potential |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2002CT | 2x10A dual common-cathode configuration; VF = 0.95V @ 10A; trr = 30ns; TO-220AC package (isolated tab) | Requires insulated mounting hardware; better suited for dual-output or interleaved designs | Select when dual-diode layout or lower trr is prioritized over single-diode simplicity and AEC-Q101 compliance |
| ON Semi MUR2020CTG | Dual common-cathode; VF = 1.1V @ 10A; trr = 60ns; TO-220AB; no AEC-Q101 qualification | Lacks automotive qualification; higher conduction loss and slower recovery than SF2004GHC0G | Acceptable for cost-sensitive industrial supplies where AEC-Q101 and <40ns trr are not required |
Compared with STTH2002CT and MUR2020CTG, SF2004GHC0G offers AEC-Q101 validation, single-diode simplicity with cathode-tab integration, and optimal balance of 0.975V VF and 35ns trr - making it preferred for space-constrained, automotive-grade 200V rectification where thermal and reliability margins are critical.

FAQ
What is the maximum junction temperature rating for SF2004GHC0G?
The SF2004GHC0G has a maximum junction temperature (TJ) of +150°C and a minimum of –55°C. This wide operating range supports use in under-hood automotive locations and industrial enclosures without active cooling. The device maintains full 20A current capability up to TC = 85°C, with linear derating beyond that point per the forward current derating curve in the SF2001G–SF2008G datasheet.
Is SF2004GHC0G pin-compatible with other devices in the SF200xG family?
Yes, SF2004GHC0G shares identical TO-220AB package dimensions, pinout (anode–cathode–tab), and mounting interface with all SF2001G–SF2008G variants. Voltage ratings differ across the family (50V–600V), but mechanical and thermal interfaces remain consistent - enabling drop-in replacement during design iteration or BOM optimization when VRRM margin allows.
Does SF2004GHC0G require a thermal pad or insulator when mounted to a heatsink?
No, SF2004GHC0G does not require an insulating pad because its metal tab is electrically connected to the cathode (Pin 2). When the heatsink is referenced to the cathode net - typical in most buck or forward converter layouts - direct mounting is safe and thermally optimal. If cathode isolation is needed, a mica or ceramic insulator must be used, and thermal resistance will increase by ~0.5–1.0°C/W.
What is the reverse recovery charge (Qrr) specification for SF2004GHC0G?
The SF2004GHC0G datasheet does not specify Qrr directly; only trr = 35ns is provided under IF = 0.5A, IR = 1.0A, Irr = 0.25A test conditions. For precise Qrr-based loss modeling, engineers should refer to the reverse recovery waveform in Figure 6 of the SF2001G–SF2008G datasheet or characterize the device in-circuit using a double-pulse test setup calibrated to those conditions.
How does the "H" and "C0G" suffix in SF2004GHC0G affect its specifications?
The "H" denotes AEC-Q101 qualification, confirming automotive-grade stress testing and reliability validation. "C0G" indicates green compound (halogen-free per IEC 61249-2-21) and date code format (YWW). These suffixes do not alter electrical parameters - SF2004GHC0G retains identical VRRM, IF, trr, and VF as SF2004G, but adds automotive qualification and environmental compliance.
