Product details
Overview
SF2002G from Taiwan Semiconductor is a 20A, 100V super fast recovery rectifier diode in TO-220AB package, featuring 35ns reverse recovery time, 0.975V forward voltage at 10A/25°C, and 150A surge current capability - used in switching-mode DC-DC converters and freewheeling paths.
For engineers reviewing the SF2002G datasheet, SF2002G pinout, SF2002G application, or SF2002G equivalent, key selection criteria include VRRM = 100V, IF = 20A, trr = 35ns, thermal resistance RθJC = 2.5°C/W, and AEC-Q101 qualification availability (SF2002GH variant).
Technical Context
The SF2002G integrates dual die configuration in a single TO-220AB package with common-cathode arrangement, enabling high-current freewheeling in half-bridge and synchronous rectification topologies. Its super fast recovery (trr ≤ 35ns) minimizes switching losses in 50–500kHz SMPS designs.
Thermal performance is defined by RθJC = 2.5°C/W and TJMAX = 150°C, supporting continuous operation up to 20A with proper heatsinking. Reverse leakage remains ≤5µA at 25°C and ≤400µA at 125°C under rated VR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage; defines safe blocking capability in 100V bus applications |
| IF | 20 A - Continuous forward current rating; supports high-power DC-DC output stages without derating below 75°C case temp |
| trr | 35 ns - Reverse recovery time; enables efficient operation in >200kHz switching converters with low turn-off loss |
| VF | 0.975 V @ 10A, 25°C - Low conduction loss; reduces power dissipation by ~2W vs. standard FRDs at same current |
| IFSM | 150 A - Non-repetitive surge rating; withstands inrush and fault currents in motor drives and UPS systems |
| RθJC | 2.5 °C/W - Junction-to-case thermal resistance; allows direct mounting to heatsink for thermal management in industrial power supplies |
Pinout & Package
TO-220AB package with 3-terminal configuration: Anode 1, Anode 2, and common Cathode. Molded thermoset compound meets UL 94V-0; matte tin-plated leads comply with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Lead 1 (Left) | Anode 1 | First diode anode; connects to high-side switch node in dual-output or interleaved converter legs |
| Lead 2 (Center) | Cathode (Common) | Shared cathode output; routes combined forward current to output capacitor or load return path |
| Lead 3 (Right) | Anode 2 | Second diode anode; enables independent control of two freewheeling paths or phase-leg redundancy |
Key Features
| Feature | Design Value |
|---|---|
| Super fast recovery | trr ≤ 35ns ensures minimal switching loss and EMI in high-frequency SMPS (>200kHz) |
| Low forward voltage | VF = 0.975V @ 10A reduces conduction loss by ~1.5W vs. comparable 100V FRDs |
| Dual-die common-cathode | Enables space-efficient dual-path rectification without external parallel diodes or layout complexity |
| AEC-Q101 qualified option | SF2002GH variant supports automotive-grade reliability for under-hood DC-DC modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2002CT | VRRM = 100V, IF = 20A, trr = 35ns, but single-die dual-common-cathode; RθJC = 2.7°C/W | Lacks dual independent anodes - unsuitable for phase-split or redundant freewheeling | Select SF2002G when independent anode control or lower thermal resistance is required |
| VS-20EWH02-M3 | VRRM = 200V, IF = 20A, trr = 30ns, TO-247AC package; higher VRRM, larger footprint | Over-spec'd voltage rating increases cost and size; not drop-in for 100V designs | Choose SF2002G for optimized 100V systems requiring TO-220AB form factor and dual-anode flexibility |
Compared with STTH2002CT and VS-20EWH02-M3, the SF2002G uniquely provides dual independent anodes in TO-220AB with best-in-class RθJC = 2.5°C/W - critical for compact, thermally constrained 100V SMPS and automotive DC-DC modules.

FAQ
What is the maximum junction temperature rating for the SF2002G?
The SF2002G has a maximum junction temperature (TJMAX) of +150°C, validated across its full operating range. This rating enables reliable operation in high-ambient environments such as enclosed power supplies and automotive under-hood modules when mounted on an appropriately sized heatsink. Thermal design must respect RθJC = 2.5°C/W to avoid exceeding TJMAX under 20A continuous load.
Does the SF2002G have AEC-Q101 qualification?
The SF2002G itself is not AEC-Q101 qualified; however, the pin-compatible SF2002GH variant is explicitly qualified per AEC-Q101 Rev D. The GH version uses identical die and TO-220AB packaging but adds enhanced process controls, wafer-level testing, and whisker-resistant plating per JESD201 Class 2 - making SF2002GH the appropriate choice for automotive applications requiring qualification evidence.
What is the reverse recovery time (trr) specification for the SF2002G?
The SF2002G has a maximum reverse recovery time (trr) of 35ns, measured under IF = 0.5A, IR = 1.0A, and Irr = 0.25A conditions. This value is confirmed across production lots and supports high-frequency switching up to 500kHz while maintaining low dynamic losses. Designers should reference Figure 6 in the official TSC datasheet for test circuit details and waveform definitions.
How is the dual-die configuration implemented in the SF2002G package?
The SF2002G integrates two independent silicon dies in a single TO-220AB package, with separate anode terminals (Leads 1 and 3) and a shared cathode terminal (Lead 2). This configuration allows independent current routing per anode - useful in interleaved converters or dual-output supplies - while maintaining mechanical and thermal integration superior to discrete diode pairs.
What is the forward voltage (VF) of the SF2002G at rated current?
The SF2002G exhibits a typical forward voltage (VF) of 0.975V at 10A and 25°C junction temperature, with no maximum specified - indicating tight process control. At full rated current (20A), VF rises predictably per the Fig.4 forward characteristic curve, remaining below 1.15V at 125°C. This low VF directly reduces conduction loss in high-current power stages.
