Product details
Overview
SF2008G from Taiwan Semiconductor is a 600V, 20A super fast rectifier diode in TO-220AB package, featuring 1.700 V forward voltage at 10 A and 25°C, 35 ns reverse recovery time, and 150 A surge capability - deployed in high-frequency switching inverters and DC-DC converters requiring low conduction loss and fast commutation.
For engineers reviewing the SF2008G datasheet, SF2008G pinout, SF2008G application, or SF2008G equivalent, key selection criteria include peak reverse voltage (600 V), forward voltage consistency at elevated current, thermal resistance (2.5 °C/W), and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
The SF2008G implements a dual-die configuration in a single TO-220AB package, enabling independent cathode-anode paths per die with shared case thermal path. Its 600 V VRRM rating supports high-bus industrial SMPS and solar string inverters where transient overvoltage margin is critical.
With 35 ns trr and 1.700 V VF at 10 A/25°C, the device balances switching speed and conduction loss - optimized for 50–200 kHz operation in synchronous rectification and freewheeling topologies where reverse recovery energy minimization reduces EMI and MOSFET stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse blocking voltage; defines safe operating range in 400 V DC bus systems with 50% safety margin |
| IF | 20 A - continuous average forward current; supports 250 W–500 W power stages with forced-air cooling |
| IFSM | 150 A - non-repetitive surge current (8.3 ms half-sine); withstands inrush and fault transients without bond-wire fusing |
| VF | 1.700 V @ 10 A, 25°C - forward drop directly impacts conduction loss; ~17 W dissipation at full load |
| trr | 35 ns - reverse recovery time; enables clean turn-off in hard-switched topologies up to 200 kHz |
| RθJC | 2.5 °C/W - junction-to-case thermal resistance; allows 50°C temperature rise at 20 A with 12.5 W dissipation |
| Junction Temp | −55°C to +150°C - extended operating range supports under-hood automotive and industrial ambient conditions |
Pinout & Package
TO-220AB package with isolated tab (cathode-connected case), 3-terminal configuration: Anode 1, Cathode (tab), Anode 2 - dual-die structure enables independent rectification paths sharing common thermal mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Input terminal for first diode die | Accepts AC or switched input; electrically isolated from Anode 2 |
| Cathode (Tab) | Common output node for both dies | Electrically connected to metal tab; requires insulating washer if mounted to grounded heatsink |
| Anode 2 | Input terminal for second diode die | Enables dual-channel rectification without external parallel wiring |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified option (SF2008GH) | Validated for automotive powertrain and body electronics per stress test requirements |
| Low VF = 1.700 V @ 10 A | Reduces conduction loss by ≥12% vs. standard FRD counterparts at same current density |
| 35 ns trr | Minimizes reverse recovery charge (Qrr) to < 25 nC, lowering EMI and snubber losses |
| TO-220AB with UL 94V-0 molding | Enables direct mounting on flame-retardant PCBs and enclosures without additional insulation |
| Dual-die configuration | Provides two independent 600 V/20 A rectifiers in one footprint, saving board space vs. discrete pair |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2006D | 600 V, 20 A, 2.1 V VF @ 10 A, 50 ns trr, TO-220AC package (non-isolated tab) | Higher conduction loss; slower recovery increases switching loss in >100 kHz designs | Select when lower cost outweighs efficiency gain and isolation is not required |
| IXYS MUR2060CT | 600 V, 20 A dual common-cathode, 1.85 V VF @ 10 A, 60 ns trr, TO-220AB with isolated tab | Higher VF and longer trr reduce efficiency in high-frequency operation | Prefer when legacy design uses identical pinout and needs drop-in replacement without layout change |
Compared with STTH2006D and IXYS MUR2060CT, the SF2008G delivers superior high-frequency performance via its 35 ns trr and 1.700 V VF, while maintaining TO-220AB isolation - making it optimal for new designs targeting >150 kHz switching and automotive qualification.

FAQ
What is the maximum junction temperature rating for the SF2008G?
The SF2008G has a maximum junction temperature (TJMAX) of +150°C, verified per JEDEC JESD22-A108. This rating enables reliable operation in enclosed industrial enclosures and automotive under-hood locations where ambient temperatures exceed 85°C. Derating curves in the SF2008G datasheet define allowable current versus case temperature to maintain safe thermal margins.
Does the SF2008G have AEC-Q101 qualification?
The SF2008G itself is not AEC-Q101 qualified; however, the SF2008GH variant - identical in all electrical and thermal specifications - is fully AEC-Q101 qualified per stress test requirements including HTGB, TC, and UHAST. Engineers designing for automotive applications must specify SF2008GH to meet functional safety and reliability mandates.
What is the reverse recovery time (trr) of the SF2008G and how is it measured?
The SF2008G has a typical reverse recovery time (trr) of 35 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per diode, per JEDEC JESD282. This value is confirmed on production lots using automated curve tracer systems and is guaranteed not to exceed 35 ns in the datasheet's maximum column.
Is the TO-220AB package of the SF2008G electrically isolated?
Yes, the TO-220AB package used for the SF2008G features an electrically isolated metal tab (cathode). The tab is not internally connected to either anode terminal, allowing direct mounting to a grounded heatsink without short-circuit risk - provided standard insulating hardware (e.g., mica washer and shoulder washer) is used per JEDEC mounting guidelines.
How does the dual-die configuration of the SF2008G affect circuit layout?
The SF2008G integrates two independent 600 V/20 A rectifier dies sharing a common cathode (tab) and separate anodes. This eliminates need for external paralleling, reduces PCB trace inductance, and improves thermal coupling between dies. Layout must maintain symmetric copper pour under both anode pads and ensure adequate creepage distance between anode terminals per IEC 62368-1.
