Product details
Overview
SFF2004G from Taiwan Semiconductor is a 20A, 200V super fast rectifier diode in ITO-220AB package with dual-die configuration, 35ns reverse recovery time, 0.975V forward voltage at 10A/25°C, and 150A surge rating - used in high-efficiency DC-DC converters and switching inverters.
For engineers reviewing the SFF2004G datasheet, SFF2004G pinout, SFF2004G application, or SFF2004G equivalent, key selection criteria include VRRM = 200V, IF = 20A, trr = 35ns, RθJC = 2.5°C/W, and AEC-Q101 qualification availability (SFF2004GH variant).
Technical Context
The SFF2004G integrates two independent super fast rectifier dies in a single ITO-220AB thermally enhanced package, enabling dual-channel freewheeling or bridge configurations without external paralleling. Its 35ns reverse recovery time and low 0.975V forward voltage at 10A directly support high-frequency (>100kHz) switching topologies.
Thermal performance is defined by a junction-to-case resistance of 2.5°C/W and a maximum junction temperature of 150°C, allowing sustained 20A conduction under forced-air or heatsink-mounted conditions per JEDEC JESD201 Class 2 whisker compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - blocks up to 200V repetitive reverse voltage, suitable for 24–48V input DC-DC stages with safety margin |
| IF | 20 A - continuous forward current rating enables use in 300–500W power supplies without derating at TC ≤ 80°C |
| trr | 35 ns - enables operation in hard-switched SMPS above 200kHz with minimal switching loss and EMI |
| VF @ 10A, 25°C | 0.975 V - reduces conduction loss to ~9.75W per diode at full load, critical for thermal management in compact designs |
| RθJC | 2.5 °C/W - allows direct heatsink mounting with <1°C/W interface resistance to maintain TJ < 125°C at 20A |
| IFSM | 150 A - withstands 8.3ms half-sine surges common in motor drive startup and input line transients |
| Junction Temp Range | −55°C to +150°C - supports automotive under-hood and industrial ambient environments |
Pinout & Package
Package: ITO-220AB - thermally optimized 3-lead through-hole package with isolated collector tab, UL 94V-0 molding compound, matte tin-plated leads, and 0.56 N·m max mounting torque.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Input terminal for first diode | Connected to high-side switch node in synchronous rectification or freewheel path |
| Cathode (Tab) | Common cathode for both diodes | Electrically and thermally connected to heatsink; requires isolation washer if chassis-grounded |
| Anode 2 | Input terminal for second diode | Enables dual independent rectification paths or center-tapped transformer secondary connection |
Key Features
| Feature | Design Value |
|---|---|
| Super fast recovery (trr = 35ns) | Minimizes turn-off loss and ringing in high-frequency flyback and LLC resonant converters |
| Dual-die configuration | Reduces board space vs. two discrete diodes; maintains matched thermal and electrical characteristics |
| Low VF (0.975V @ 10A) | Lowers conduction loss by >15% versus standard fast rectifiers, improving efficiency in 12–48V output rails |
| UL Recognized (E-326243) | Meets end-equipment safety certification requirements without additional component-level testing |
| AEC-Q101 qualified option | SFF2004GH variant supports automotive power modules requiring stress-tested reliability |
Applications
| DC-DC Converter | Switching Inverter |
|---|---|
Use Scenario: Secondary-side synchronous rectification in isolated 48V-to-12V buck-derived converters for telecom and server PSUs. IC Role / Device Role / Timing Role: Super fast rectifier replacing Schottky diodes where higher VRRM and lower leakage are required. Use Value: Enables 200V blocking capability with 35ns trr, reducing switching loss by 22% vs. 600V FRDs while maintaining thermal margin. | Use Scenario: Freewheeling path in 3-phase motor drive inverters operating at 8–20kHz PWM frequency. IC Role / Device Role / Timing Role: Dual-anode configuration provides independent return paths for upper/lower leg shoot-through protection. Use Value: Dual-die layout avoids interconnect inductance; 2.5°C/W RθJC sustains 20A continuous current with 40°C/W heatsink. |
| Industrial Power Supply | Automotive DC-DC Module |

IC Role / Device Role / Timing Role: AEC-Q101-qualified SFF2004GH variant ensures reliability under −40°C to +125°C under-hood conditions. Use Value: Validated for automotive stress profiles including temperature cycling, humidity, and mechanical shock - no field failure history reported. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-20EWH06-M3 | 600V VRRM, 30ns trr, same ITO-220AB package, but 1.25V VF @ 10A | Better for 400–600V bus systems; higher VF increases conduction loss in 200V designs | Select only when higher voltage margin is prioritized over efficiency at 200V operation |
| ON Semiconductor MUR2020CT | 200V VRRM, 35ns trr, TO-220AB package, but single-die dual common-cathode configuration | Lacks independent anodes; unsuitable for split-winding or asymmetric freewheeling topologies | Use when dual common-cathode suffices and board layout does not require isolated anode routing |
Compared with VS-20EWH06-M3 and MUR2020CT, the SFF2004G uniquely combines 200V rating, 35ns recovery, dual independent anodes, and 0.975V forward drop - making it optimal for space-constrained, high-efficiency 200V DC-DC and inverter freewheeling where thermal and layout flexibility matter.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for the SFF2004G?
The SFF2004G has a VRRM of 200 V, confirmed in the Absolute Maximum Ratings table across all versions I2105 documentation. This rating defines the highest reverse voltage the device can block repeatedly without breakdown and aligns with its "2004" part-number suffix. The SFF2004G is not rated for 300V or higher - that applies to SFF2005G and above.
Does the SFF2004G have AEC-Q101 qualification?
The base SFF2004G is not AEC-Q101 qualified; however, the SFF2004GH variant - indicated by the "H" suffix in the ordering code - is explicitly AEC-Q101 qualified per the Ordering Information section. Both share identical electrical and thermal specs, but only SFF2004GH undergoes automotive-grade stress testing and screening.
What is the forward voltage (VF) of the SFF2004G at rated current?
The SFF2004G exhibits a typical forward voltage of 0.975 V at IF = 10 A and TJ = 25°C, as specified in the Electrical Specifications table. This value is measured per diode under pulse conditions (PW = 0.3 ms), and remains stable across the 25–125°C junction range with predictable positive temperature coefficient.
How many diodes are integrated into the SFF2004G package?
The SFF2004G contains two independent super fast rectifier dies in a single ITO-220AB package, configured as dual-anode, common-cathode (tab). This is explicitly stated under "Configuration: Dual dies" and verified by the pinout - Anode 1, Anode 2, and shared Cathode (tab) - enabling flexible circuit implementations without external paralleling.
What is the thermal resistance from junction to case (RθJC) for the SFF2004G?
The SFF2004G has a typical junction-to-case thermal resistance (RθJC) of 2.5°C/W, as published in the Thermal Performance section. This value is measured with the cathode tab mounted to a standard heatsink per JESD51-14, and enables accurate thermal modeling for heatsink sizing in continuous 20A operation.
