Product details
Overview
SFAF1608GHC0G from Taiwan Semiconductor is a 16A, 600V super fast rectifier diode in ITO-220AC package, featuring 1.700V forward voltage at 16A/25°C, 35ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in high-frequency DC-DC converters requiring low conduction loss and fast switching.
For engineers reviewing the SFAF1608GHC0G datasheet, SFAF1608GHC0G pinout, SFAF1608GHC0G application, or SFAF1608GHC0G equivalent, key selection factors include its 600V VRRM, 200A IFSM, junction-to-case thermal resistance of 1.3°C/W, AEC-Q101 qualification status, and ITO-220AC mechanical compatibility with standard heatsink mounting.
Technical Context
This super fast rectifier uses a glass-passivated silicon junction to achieve high surge current capability (200A, 8.3ms half-sine) and stable operation up to 150°C junction temperature. Its 35ns reverse recovery time and low junction capacitance (100pF at 4V) support efficient operation in 100–500kHz switching topologies.
The device implements a single-die configuration in ITO-220AC housing with matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. Polarity is marked on the case, and the molding compound meets UL 94V-0 flammability rating.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1606D | 600V VRRM, 1.75V VF @ 16A, 50ns trr, TO-220AC package | Higher VF and slower trr increase conduction and switching loss in >150kHz designs | Acceptable where thermal headroom exists and switching frequency ≤100kHz |
| IXYS MUR1660CT | 600V VRRM, dual common-cathode configuration, 1.85V VF, 60ns trr, TO-220AB | Dual-diode layout requires PCB redesign; higher VF and trr reduce efficiency vs. SFAF1608GHC0G | Only suitable when dual-diode topology is required; not a drop-in replacement |
Compared with STTH1606D and IXYS MUR1660CT, the SFAF1608GHC0G delivers superior high-frequency efficiency due to its 35ns trr and lower VF, while maintaining AEC-Q101 qualification-critical for automotive and high-reliability industrial use cases where thermal and transient robustness are prioritized.

FAQ
What is the maximum junction temperature rating for SFAF1608GHC0G?
The SFAF1608GHC0G has a maximum junction temperature (TJ) rating of +150°C, with a storage temperature range of −55°C to +150°C. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial settings. Thermal design must maintain junction temperature below this limit using the specified 1.3°C/W junction-to-case resistance and appropriate heatsinking. The SFAF1608GHC0G datasheet confirms derating curves down to zero current at 150°C case temperature.
Is SFAF1608GHC0G pin-compatible with standard ITO-220AC rectifiers?
Yes, the SFAF1608GHC0G uses the industry-standard ITO-220AC package with Anode, Cathode, and isolated Tab terminals in identical mechanical footprint and lead pitch. Mounting torque must not exceed 0.56 N·m, and polarity is marked on the case per standard orientation. The SFAF1608GHC0G maintains full mechanical compatibility with existing ITO-220AC heatsink fixtures and PCB footprints.
Does SFAF1608GHC0G meet automotive qualification standards?
Yes, the 'H' suffix in SFAF1608GHC0G denotes AEC-Q101 qualification, verified per stress tests including high-temperature operating life, temperature cycling, and highly accelerated stress testing. This makes the SFAF1608GHC0G suitable for automotive powertrain and chassis applications where reliability under thermal and vibration stress is mandatory. The SFAF1608GHC0G UL Recognition File #E-326243 further supports safety compliance.
What is the reverse recovery time (trr) specification for SFAF1608GHC0G?
The SFAF1608GHC0G has a maximum reverse recovery time (trr) of 35 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed across the full operating temperature range and supports high-frequency switching up to 500 kHz with minimal commutation loss. The SFAF1608GHC0G achieves this performance via optimized carrier lifetime control in its super fast silicon structure.
How does the forward voltage of SFAF1608GHC0G compare across temperature?
The SFAF1608GHC0G exhibits a positive temperature coefficient for forward voltage: VF decreases slightly as junction temperature rises, from 1.700 V at 25°C to approximately 1.55 V at 125°C (per typical curve Fig.4). This behavior improves thermal stability in parallel configurations. The SFAF1608GHC0G datasheet specifies VF only at 25°C and 100°C, with no maximum limit at elevated temperatures-consistent with silicon super fast rectifier characteristics.
