Product details
Overview
SFF2006G from Taiwan Semiconductor is a 400 V, 20 A super fast rectifier diode in ITO-220AB package with dual-die configuration, 1.300 V forward voltage at 10 A/25°C, 35 ns reverse recovery time, and 150 A surge capability - used in high-efficiency DC-DC converters and switching inverters.
For engineers reviewing the SFF2006G datasheet, SFF2006G pinout, SFF2006G application, or SFF2006G equivalent, key selection criteria include rated VRRM (400 V), thermal resistance RθJC (2.5 °C/W), junction temperature limit (150 °C), and AEC-Q101 qualification status (SFF2006GH variant only).
Technical Context
The SFF2006G implements a super fast recovery silicon PN junction optimized for high-frequency switching power supplies. Its 35 ns trr and low 1.300 V VF at 10 A reduce conduction and switching losses in hard-switched topologies.
Rated for 400 V repetitive peak reverse voltage and 150 A non-repetitive surge current (8.3 ms half-sine), it supports robust operation in automotive-grade DC-DC modules when specified as SFF2006GH, meeting AEC-Q101 Class 2 whisker testing and UL 94V-0 molding compound requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum blocking voltage in reverse bias; defines usable input voltage range in buck/boost converters |
| IF | 20 A continuous - average forward current rating at case temperature ≤ 75°C; determines heatsink sizing |
| IFSM | 150 A (8.3 ms) - peak surge withstand capability; critical for inrush and fault transient handling |
| VF | 1.300 V @ 10 A, 25°C - forward conduction loss per diode; directly impacts efficiency and thermal design |
| trr | 35 ns - reverse recovery time; enables operation up to ~3 MHz switching frequency with minimal switching loss |
| RθJC | 2.5 °C/W - junction-to-case thermal resistance; enables direct mounting to heatsink without thermal interface material |
| Junction Temp | −55°C to +150°C - operating 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 |
|---|---|---|---|
| STTH2004D | 400 V VRRM, 20 A IF, 30 ns trr, TO-220AC package (non-isolated tab) | Non-isolated tab requires thermal pad; lower trr suits higher-frequency designs | Select when tab isolation is unnecessary and 30 ns recovery provides measurable efficiency gain |
| VS-20EWH04FN-M3 | 400 V VRRM, 20 A IF, 35 ns trr, TO-247AC package, AEC-Q101 qualified | Larger TO-247 footprint; higher RθJC (3.0 °C/W); same isolation not guaranteed | Choose for legacy TO-247 layouts or where higher surge margin (200 A IFSM) is required |
Compared with STTH2004D and VS-20EWH04FN-M3, the SFF2006G offers electrically isolated tab in compact ITO-220AB, enabling simplified heatsinking in space-constrained automotive and industrial modules without sacrificing 35 ns recovery performance.

FAQ
What is the maximum junction temperature rating for the SFF2006G?
The SFF2006G has a maximum junction temperature (TJ) of +150°C, verified across its full operating range from −55°C to +150°C. This rating supports deployment in under-hood automotive environments and high-ambient industrial enclosures. Derating curves in the datasheet define allowable IF versus case temperature, ensuring safe operation within this thermal limit for the SFF2006G.
Is the SFF2006G pin-compatible with other devices in the SFF200xG series?
Yes, all SFF2001G through SFF2008G share identical ITO-220AB package dimensions, pinout, and thermal/mechanical specifications. Only VRRM (50–600 V), VF, and IR vary across the series. The SFF2006G maintains full mechanical and layout compatibility with SFF2001G–SFF2008G, enabling voltage-scaling without PCB redesign.
Does the SFF2006G have AEC-Q101 qualification?
The base SFF2006G is not AEC-Q101 qualified; however, the SFF2006GH variant is fully AEC-Q101 qualified and shares identical electrical and thermal specs. The "H" suffix denotes qualification per AEC-Q101 Rev D, including stress tests for temperature cycling, humidity, and whisker resistance. Always specify SFF2006GH for automotive applications requiring AEC compliance.
What is the reverse recovery time (trr) specification for the SFF2006G?
The SFF2006G 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 under standardized pulse conditions and enables reliable operation in switching power supplies up to 1 MHz. The trr remains stable across temperature, supporting consistent performance in the SFF2006G across its full operating range.
How does the ITO-220AB package of the SFF2006G differ from standard TO-220AB?
The ITO-220AB package features an electrically isolated metal tab, unlike standard TO-220AB where the tab connects to the cathode. This isolation allows direct mounting to grounded heatsinks without insulation hardware. The SFF2006G leverages this to simplify thermal design while maintaining 2.5 °C/W RθJC - a key differentiator for compact, high-power-density applications using the SFF2006G.
