Product details
Overview
SFAF1608G 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 100pF junction capacitance - deployed in high-frequency DC-DC converters requiring low-loss freewheeling paths.
For engineers reviewing the SFAF1608G datasheet, SFAF1608G pinout, SFAF1608G application, or SFAF1608G equivalent, key selection criteria include VRRM = 600V, IF = 16A, trr = 35ns, RθJC = 1.3°C/W, and AEC-Q101 qualification availability (SFAF1608GH variant).
Technical Context
This super fast rectifier uses glass-passivated silicon die to achieve low conduction loss and rapid carrier recombination. Its 35ns reverse recovery time enables operation in switching-mode power supplies above 100kHz while maintaining low EMI and minimal switching loss.
The ITO-220AC package provides direct heatsink mounting with 1.3°C/W junction-to-case thermal resistance. Polarity is marked on the device body, and terminals are matte tin-plated per J-STD-002 for reliable solderability.

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 | VRRM = 600V, trr = 35ns, VF = 1.75V @ 16A - slightly higher VF, same package | Qualified to AEC-Q101 Grade 0; identical thermal performance but higher forward loss | Preferred where automotive qualification is mandatory and 50mV VF penalty is acceptable |
| IXYS MUR1660CT | Dual common-cathode configuration (16A ×2), trr = 35ns, VF = 1.7V - requires layout change for single-diode use | Designed for dual-output or interleaved designs; not drop-in for single-diode footprints | Select when dual-channel rectification is needed or board space permits repartitioning |
Compared with STTH1606D and IXYS MUR1660CT, the SFAF1608G offers lower forward voltage than STTH1606D and simpler single-diode integration than MUR1660CT - making it optimal for cost-sensitive, space-constrained 600V single-channel SMPS designs.

FAQ
What is the maximum junction temperature rating for the SFAF1608G?
The SFAF1608G has a maximum junction temperature (TJ) of +150°C, with storage temperature ranging from –55°C to +150°C. This rating allows operation in high-ambient environments such as enclosed industrial enclosures or under-hood automotive locations when properly heatsinked.
Is the SFAF1608G pin-compatible with other devices in the SFAF16xxG series?
Yes, all SFAF16xxG variants - including SFAF1608G - share identical ITO-220AC packaging, pinout, and mechanical dimensions. Only VRRM, VF, and CJ differ across the series; no PCB redesign is required when upgrading voltage rating within the family.
Does the SFAF1608G meet automotive reliability standards?
The base SFAF1608G is not AEC-Q101 qualified, but the SFAF1608GH variant is fully AEC-Q101 qualified and tested per stress test conditions for automotive under-hood applications. Always specify the "H" suffix for automotive-grade ordering.
What is the reverse leakage current specification for the SFAF1608G at elevated temperature?
At TJ = 100°C and rated VR, the SFAF1608G exhibits a maximum reverse leakage current (IR) of 400 µA. At 25°C, IR is limited to 10 µA - supporting low standby power in energy-efficient power supplies.
How is thermal performance characterized for the SFAF1608G?
The SFAF1608G has a junction-to-case thermal resistance (RθJC) of 1.3°C/W, measured under standard mounting conditions. This value assumes direct metal-to-metal contact between the ITO-220AC case and a heatsink with appropriate torque (≤0.56 N·m) and thermal interface material.
