Product details
Overview
SFAF2008GHC0G from Taiwan Semiconductor is a 20 A, 600 V super fast rectifier diode in ITO-220AC package, featuring 1.700 V forward voltage at 20 A and 25 °C, 35 ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability in freewheeling and DC-DC converter applications.
For engineers reviewing the SFAF2008GHC0G datasheet, SFAF2008GHC0G pinout, SFAF2008GHC0G application, or SFAF2008GHC0G equivalent, key selection criteria include peak reverse voltage (600 V), surge current capability (200 A), junction-to-case thermal resistance (3 °C/W), and AEC-Q101 qualification status for harsh-environment deployment.
Technical Context
This super fast rectifier uses a glass-passivated single-die silicon junction optimized for high-efficiency switching power supplies. Its 35 ns trr and low Qrr support high-frequency operation up to several hundred kHz while minimizing switching losses in flyback and forward converters.
The device operates across -55 °C to +150 °C junction temperature range with 3 °C/W junction-to-case thermal resistance, enabling direct heatsink mounting without isolation washers in space-constrained industrial and automotive power stages.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2006D | 600 V VRRM, 1.85 V VF @ 20 A, 50 ns trr, TO-220AC package | Higher VF increases conduction loss; slower trr limits max switching frequency | Acceptable where thermal headroom exists and switching frequency ≤150 kHz |

FAQ
What is the peak repetitive reverse voltage rating of the SFAF2008GHC0G?
The SFAF2008GHC0G has a peak repetitive reverse voltage (VRRM) rating of 600 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version J2105), and defines the maximum reverse-biased voltage the device can block continuously without breakdown. It supports use in 400 VAC rectification and 300–400 V DC-link applications with adequate safety margin.
Is the SFAF2008GHC0G qualified to AEC-Q101 standards?
Yes, the SFAF2008GHC0G is AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. This qualification covers stress tests including HTGB, HTRB, TCT, and ESD, confirming suitability for automotive under-hood power modules and ADAS subsystems.
What is the forward voltage drop of the SFAF2008GHC0G at rated current?
The SFAF2008GHC0G exhibits a maximum forward voltage (VF) of 1.700 V at 20 A and 25 °C, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents worst-case conduction loss at room temperature; VF increases with junction temperature and must be derated accordingly in thermal design.
Does the SFAF2008GHC0G have an electrically isolated package?
Yes, the SFAF2008GHC0G uses the ITO-220AC package, where the metal tab is electrically isolated from both anode and cathode terminals. This isolation enables direct heatsink mounting without insulating pads or hardware, simplifying thermal design while maintaining creepage/clearance compliance in high-voltage applications.
What is the reverse recovery time specification for the SFAF2008GHC0G?
The reverse recovery time (trr) of the SFAF2008GHC0G is specified as 35 ns maximum, tested at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This fast recovery characteristic minimizes switching losses and EMI generation in high-frequency SMPS topologies such as active clamp flyback and LLC resonant converters.
