Product details
Overview
SFAF1604GH from Taiwan Semiconductor is a 16A, 200V repetitive peak reverse voltage (VRRM) super fast rectifier diode in ITO-220AC package, featuring 35ns reverse recovery time (trr), 0.975V forward voltage at 16A/25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in high-frequency DC-DC converters.
For engineers reviewing the SFAF1604GH datasheet, SFAF1604GH pinout, SFAF1604GH application, or SFAF1604GH equivalent, key selection criteria include VRRM=200V, trr=35ns, VF=0.975V @16A, junction-to-case thermal resistance of 1.3°C/W, and AEC-Q101 qualification status.
Technical Context
The SFAF1604GH employs a glass-passivated single-die silicon junction optimized for switching-mode power supplies. Its 35ns reverse recovery time enables operation at frequencies up to several hundred kHz without excessive switching loss.
With a rated average forward current of 16A and 200A non-repetitive surge capability (8.3ms half-sine), it supports high-pulse-load applications such as freewheeling in motor drives and inverters while maintaining TJ ≤150°C under proper heatsinking.
Key Specifications

| VRRM | 200 V - Maximum repetitive reverse blocking voltage; defines usable input/output voltage range in DC-DC stages |
| IF | 16 A - Continuous average forward current rating at case temperature ≤75°C with adequate heatsink |
| trr | 35 ns - Reverse recovery time at IF=0.5A, IR=1.0A, Irr=0.25A; enables efficient high-frequency switching |
| VF | 0.975 V @16A, 25°C - Low conduction loss improves system efficiency and reduces thermal stress |
| RθJC | 1.3 °C/W - Junction-to-case thermal resistance; determines minimum heatsink requirement for thermal management |
| IFSM | 200 A - Peak non-repetitive surge current handling for startup or fault transients |
| Junction Temp | –55°C to +150°C - Operating temperature range compatible with under-hood automotive environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1602D | VRRM=200V, trr=35ns, VF=0.95V @16A, but not AEC-Q101 qualified | Lacks automotive qualification; suitable for industrial/commercial SMPS only | Select when AEC-Q101 is not required and lowest VF is prioritized |
| IXYS MUR1620CT | Dual common-cathode configuration (2×8A), VRRM=200V, trr=35ns, VF=0.92V @8A per die | Requires PCB layout change due to dual-diode footprint and different pinout | Choose for space-constrained dual-output designs where shared cathode simplifies routing |
Compared with STTH1602D and IXYS MUR1620CT, the SFAF1604GH uniquely combines AEC-Q101 qualification, single-diode ITO-220AC form factor, and verified 200V/16A/35ns performance-making it optimal for automotive DC-DC and inverter freewheeling where qualification and mechanical compatibility are mandatory.

FAQ
What is the maximum junction temperature rating for the SFAF1604GH?
The SFAF1604GH has a maximum junction temperature (TJ) rating of +150°C, with operational storage temperature ranging from –55°C to +150°C. This rating allows deployment in under-hood automotive environments and high-ambient industrial enclosures when mounted on a heatsink providing ≤1.3°C/W thermal resistance from junction to case.
Is the SFAF1604GH pin-compatible with standard TO-220AC rectifiers?
Yes, the SFAF1604GH uses the ITO-220AC package, which shares identical mechanical dimensions and lead spacing with TO-220AC but features an electrically isolated metal tab. This allows direct mechanical replacement in existing TO-220AC footprints without PCB redesign, though electrical isolation must be verified in the target circuit layout.
Does the SFAF1604GH meet RoHS and halogen-free requirements?
Yes, the SFAF1604GH is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound meets UL 94V-0 flammability rating, and all plating and materials comply with automotive and industrial environmental directives without requiring exemptions.
What is the reverse recovery time test condition for the SFAF1604GH?
The SFAF1604GH reverse recovery time (trr) of 35ns is measured under the condition: IF = 0.5A, IR = 1.0A, Irr = 0.25A, with specified pulse waveforms. This standardized test reflects real-world behavior in high-frequency switching circuits such as 200–500kHz DC-DC converters.
How does the "H" suffix in SFAF1604GH affect its specifications?
The "H" suffix in SFAF1604GH denotes full AEC-Q101 qualification, including stress testing for temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge. Electrical and thermal specs remain identical to the non-H version (SFAF1604G), but the "H" variant carries certified test reports and lot-level traceability required for automotive production.
