Product details
Overview
SFF1001G from Taiwan Semiconductor is a 10A, 50V super fast rectifier diode in ITO-220AB package, featuring 0.975V forward voltage at 5A/25°C, 125A surge capability, and 35ns reverse recovery time-designed for high-efficiency DC-DC converters and freewheeling paths in automotive-grade power supplies.
For engineers reviewing the SFF1001G datasheet, SFF1001G pinout, SFF1001G application, or SFF1001G equivalent, key selection criteria include its 50V VRRM, dual-die configuration, AEC-Q101 qualification option (SFF1001GH), UL recognition (E-326243), and thermal resistance of 2°C/W-critical for thermally constrained switching power stages.
Technical Context
The SFF1001G is a single-phase, dual-die super fast recovery rectifier optimized for high-frequency switching applications. Its 35ns trr and low 0.975V VF at 5A enable reduced conduction and switching losses in SMPS topologies operating up to several hundred kHz.
Rated for 150°C junction temperature and housed in ITO-220AB with matte tin-plated leads, it supports high-reliability mounting per J-STD-002 and meets JESD201 Class 2 whisker resistance-making it suitable for under-hood automotive power modules where thermal cycling and vibration endurance are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 12–24V input DC-DC stages |
| IF | 10 A - Continuous forward current rating; supports sustained output currents in 100–300W converters |
| IFSM | 125 A - Non-repetitive surge current (8.3ms half-sine); handles startup inrush and transient overloads |
| VF @ 5A, 25°C | 0.975 V - Low conduction loss; reduces power dissipation to ~4.9W at full rated DC current |
| trr | 35 ns - Fast reverse recovery; minimizes switching loss and EMI in hard-switched topologies |
| RθJC | 2 °C/W - Junction-to-case thermal resistance; enables direct heatsink mounting for efficient thermal management |
| CJ @ 1MHz, 4V | 70 pF - Low junction capacitance; preserves high-frequency efficiency and reduces capacitive turn-on loss |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH10R06DJF | 600V VRRM, 35ns trr, 1.05V VF @ 5A - higher voltage rating but same speed and slightly higher VF | Targeted at 400V+ PFC and boost stages; less optimal for 50V systems due to higher stored charge | Select SFF1001G for 12–24V input DC-DC where lower VRRM improves softness and reduces leakage |
| VS-10EQ050-M3 | 50V VRRM, 30ns trr, 0.92V VF @ 5A - marginally faster and lower VF, but no AEC-Q101 option | Used in consumer-grade computing PSUs; lacks automotive qualification and UL file | Choose SFF1001G when AEC-Q101 compliance or UL recognition is required for certified designs |
Compared with STTH10R06DJF and VS-10EQ050-M3, the SFF1001G uniquely balances 50V optimization, AEC-Q101 availability, UL recognition, and 2°C/W thermal resistance-making it the preferred choice for thermally dense, automotive-qualified 12–24V power conversion.

FAQ
What is the maximum junction temperature rating for the SFF1001G?
The SFF1001G has a maximum junction temperature (TJ) rating of +150°C, with operational storage temperature ranging from –55°C to +150°C. This rating supports use in under-hood automotive environments and high-ambient industrial enclosures when mounted to an appropriate heatsink with ≤0.56 N·m torque.
Does the SFF1001G have AEC-Q101 qualification?
The base SFF1001G is not AEC-Q101 qualified, but the variant SFF1001GH is explicitly listed as AEC-Q101 qualified in the ordering information. The "H" suffix denotes qualification per AEC-Q101 stress test requirements, including HTGB, HTRB, and temperature cycling.
What is the reverse recovery time (trr) specification for the SFF1001G?
The SFF1001G 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 in the Electrical Specifications table and applies across the full operating temperature range.
Is the ITO-220AB package of the SFF1001G electrically isolated?
Yes, the ITO-220AB package used for the SFF1001G features an electrically isolated metal tab. The tab serves solely as a thermal interface and is not connected to either anode or cathode-enabling safe mounting to grounded heatsinks without short-circuit risk.
What is the UL recognition status of the SFF1001G?
The SFF1001G is UL Recognized under File #E-326243. This certification covers the device's flammability rating (UL 94V-0), terminal plating (matte tin per J-STD-002), and overall construction-supporting end-equipment safety approvals in industrial and automotive power supplies.
