Product details
Overview
SFF2004GHC0G from Taiwan Semiconductor is a 20A, 200V super fast rectifier diode in ITO-220AB package with dual-die configuration, VF = 0.975V at IF = 10A and TJ = 25°C, trr = 35ns, and RθJC = 2.5°C/W - used in DC-DC converters and switching-mode inverters for high-efficiency freewheeling.
For engineers reviewing the SFF2004GHC0G datasheet, SFF2004GHC0G pinout, SFF2004GHC0G application, or SFF2004GHC0G equivalent, key selection criteria include peak reverse voltage (200V), surge current rating (150A), junction temperature range (–55°C to +150°C), AEC-Q101 qualification, and thermal resistance for thermal design validation.
Technical Context
This super fast rectifier employs optimized epitaxial structure and diffusion process to achieve low forward voltage and ultra-fast recovery time. Its dual-die configuration enables symmetrical thermal distribution and supports parallel operation in high-current designs.
The device operates across –55°C to +150°C junction temperature range with 2.5°C/W junction-to-case thermal resistance, enabling direct heatsink mounting without isolation washers in industrial power supplies. Reverse leakage remains ≤10µA at 25°C and ≤400µA at 125°C under rated VR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum repetitive reverse blocking voltage; defines safe operating limit in flyback/freewheeling paths |
| IF | 20 A - average forward current; determines continuous conduction capability in DC-DC output stages |
| IFSM | 150 A - non-repetitive surge current (8.3ms half-sine); withstands startup/inrush transients |
| VF @ 10A, 25°C | 0.975 V - forward voltage drop per diode; directly impacts conduction loss and thermal rise |
| trr | 35 ns - reverse recovery time; enables high-frequency switching (>100 kHz) with minimal switching loss |
| RθJC | 2.5 °C/W - thermal resistance from junction to case; enables accurate heatsink sizing for 20A operation |
| TJ max | +150 °C - maximum junction temperature; sets upper thermal boundary for reliability margining |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2002CW | 20A, 200V, VF = 1.05V @ 10A, trr = 30ns, TO-247AC package | Higher VF increases conduction loss; TO-247 requires insulating hardware for heatsink mounting | Prefer when faster trr is prioritized over thermal resistance or automotive qualification |
| ON Semi MUR2020CT | 20A, 200V, VF = 1.1V @ 10A, trr = 35ns, TO-220AB package, no AEC-Q101 | Same package footprint but lacks AEC-Q101 and has higher VF; RθJC = 3.0°C/W | Acceptable for industrial-only use where qualification and 0.125V lower VF justify cost premium |
Compared with STTH2002CW and MUR2020CT, the SFF2004GHC0G delivers the lowest VF in its class, AEC-Q101 qualification, and best thermal resistance - making it optimal for thermally constrained, automotive-grade, or high-efficiency DC-DC designs.

FAQ
What is the peak repetitive reverse voltage rating of the SFF2004GHC0G?
The SFF2004GHC0G has a peak repetitive reverse voltage (VRRM) rating of 200 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version I2105), where SFF2004G is explicitly listed under the 200 V column. It defines the maximum reverse-biased voltage the device can block continuously without breakdown.
Is the SFF2004GHC0G AEC-Q101 qualified?
Yes, the SFF2004GHC0G is AEC-Q101 qualified. The "H" suffix in the ordering code denotes AEC-Q101 qualification, and this is explicitly stated in the FEATURES section and Ordering Information notes of the Taiwan Semiconductor datasheet. The device meets stress test requirements for automotive power electronics applications.
What is the forward voltage drop of the SFF2004GHC0G at 10A and 25°C?
The forward voltage drop (VF) of the SFF2004GHC0G is 0.975 V at IF = 10 A and TJ = 25°C. This value is specified in the Electrical Specifications table under "Forward voltage per diode" for the SFF2004G variant and is measured using a 0.3 ms pulse test per note (1) in the datasheet.
Does the SFF2004GHC0G have a common-cathode configuration?
Yes, the SFF2004GHC0G uses a common-cathode dual-die configuration. The datasheet's marking diagram and mechanical outline confirm a single cathode terminal shared between both diodes, with separate anodes - enabling two independent input paths feeding one output rail, ideal for interleaved or dual-phase rectification.
What is the junction-to-case thermal resistance of the SFF2004GHC0G?
The junction-to-case thermal resistance (RθJC) of the SFF2004GHC0G is 2.5°C/W. This value is published in the Thermal Performance section of the datasheet and applies to the ITO-220AB package with proper mounting torque (≤0.56 N·m). It enables precise heatsink thermal modeling for 20A continuous operation.
