Product details
Overview
SFF1001GA C0G from Taiwan Semiconductor is a 10A, 50V super fast recovery rectifier diode in ITO-220AB package with dual-die configuration, 0.975V max forward voltage at 5A/25°C, 35ns reverse recovery time, and 2°C/W junction-to-case thermal resistance - used in DC-DC converters and freewheeling paths.
For engineers reviewing the SFF1001GA C0G datasheet, SFF1001GA C0G pinout, SFF1001GA C0G application, or SFF1001GA C0G equivalent, key selection criteria include repetitive peak reverse voltage (50V), surge current rating (125A), AEC-Q101 qualification status, thermal performance, and UL recognition (E-326243).
Technical Context
This super fast rectifier employs planar epitaxial construction for low reverse recovery charge and controlled soft recovery behavior. Its dual-die ITO-220AB configuration supports high-current freewheeling with symmetrical thermal path to the case.
The device operates across -55°C to +150°C junction temperature range and delivers stable 10µA max reverse leakage at 25°C and 400µA at 125°C under rated 50V reverse bias - enabling reliable operation in switching-mode power supplies with tight thermal margins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (Continuous Forward Current) | 10 A - supports sustained conduction in high-duty-cycle DC-DC output stages |
| VRRM (Repetitive Peak Reverse Voltage) | 50 V - defines maximum blocking capability in low-voltage buck/flyback secondary side |
| IFSM (Surge Forward Current) | 125 A - withstands inrush and transient overloads without failure |
| trr (Reverse Recovery Time) | 35 ns - minimizes switching losses and EMI in 100–500 kHz SMPS designs |
| RθJC (Junction-to-Case Thermal Resistance) | 2 °C/W - enables efficient heatsinking with minimal temperature rise at full load |
| CJ (Junction Capacitance) | 70 pF - limits capacitive turn-on loss and high-frequency ringing |
| TJ Max (Maximum Junction Temperature) | 150 °C - allows operation in automotive under-hood and industrial ambient environments |

|---|---|
Use Scenario: High-efficiency synchronous or non-synchronous buck converter output stage operating at 200–500 kHz. IC Role / Device Role / Timing Role: Primary unidirectional current path delivering regulated 3.3–12 V output; blocks reverse current during high-side switch off-time. Use Value: 35 ns trr and 0.975 V VF minimize switching and conduction losses, directly improving system efficiency by up to 1.2% at 10 A load. | Use Scenario: Freewheeling path in half-bridge motor drive inverters handling inductive back-EMF during PWM dead-time. IC Role / Device Role / Timing Role: Provides low-loss recirculation path for inductor current when both bridge switches are off. Use Value: Dual-die structure and 125 A IFSM ensure robust handling of repetitive inductive surges without thermal runaway. |
| Automotive On-Board Charger (OBC) Auxiliary Supply | Industrial PLC Power Module Input Stage |
Use Scenario: Secondary-side rectification in isolated auxiliary power supply for gate drivers and MCU in 6.6 kW OBC systems. IC Role / Device Role / Timing Role: Converts transformer-isolated AC to stable DC rail; operates continuously at elevated ambient temperatures. Use Value: 150°C TJ max and AEC-Q101 qualification enable reliable operation in under-hood environments with >85°C case temperature. | Use Scenario: Input rectification in 24–48 V industrial PLC power modules requiring long-term stability and surge immunity. IC Role / Device Role / Timing Role: Front-end AC/DC or DC/DC input stage handling line transients and hot-swap events.

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 | 600 V VRRM, 1.7 V VF @ 5A, TO-220AC package, single die | Higher voltage rating but higher VF and slower trr (≈50 ns); not drop-in for 50 V designs | Select only if system requires >100 V blocking or legacy board reuse with TO-220AC footprint |
| ON Semi MUR1050CT | 50 V VRRM, 10 A IF, TO-220AB dual common-cathode, 35 ns trr, 0.95 V VF | Same voltage/current class and recovery speed; identical dual-diode topology and pinout | Direct functional alternative with validated performance in identical freewheeling and DC-DC roles |
Compared with STTH10R06DJF, SFF1001GA C0G offers lower VF and faster trr at 50 V, while ON Semi MUR1050CT matches its voltage, speed, and dual-die layout - making it the closest functional and mechanical alternative for new designs targeting cost and thermal optimization.

FAQ
What is the maximum junction temperature rating for SFF1001GA C0G?
The SFF1001GA C0G has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet (Version M2105). This rating allows continuous operation in high-ambient environments such as automotive under-hood or industrial control cabinets. Derating curves confirm usable current capacity down to 0 A at 150°C case temperature, ensuring safe thermal margin in real-world layouts.
Is SFF1001GA C0G AEC-Q101 qualified?
SFF1001GA C0G itself is not marked as AEC-Q101 qualified; however, the SFF1001GH variant (same electrical specs, "H" suffix) is explicitly AEC-Q101 qualified per the ordering information table in the Taiwan Semiconductor datasheet. For automotive applications requiring qualification, SFF1001GH must be specified - SFF1001GA C0G is intended for industrial and commercial use.
What does the "C0G" suffix indicate in SFF1001GA C0G?
The "C0G" suffix in SFF1001GA C0G is a Taiwan Semiconductor internal marking code denoting green compound (halogen-free) molding material compliant with IEC 61249-2-21, and is unrelated to ceramic capacitor C0G dielectric. It confirms RoHS compliance and environmental specification - not a functional or parametric variant. All SFF1001G variants share identical electrical characteristics regardless of C0G or other suffixes.
What is the reverse recovery time (trr) test condition for SFF1001GA C0G?
The reverse recovery time (trr) of 35 ns for SFF1001GA C0G is measured under the conditions: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, per the Electrical Specifications table in the Taiwan Semiconductor datasheet. This standardized test ensures consistent comparison across super fast rectifiers and reflects real-world performance in hard-switched topologies like buck converters.
Can SFF1001GA C0G be used as a direct replacement for MUR1050CT?
SFF1001GA C0G is not a pin-compatible replacement for MUR1050CT due to different pin assignments: MUR1050CT uses common-cathode dual-diode pinout (pins 1&2 anodes, pin 3 cathode), while SFF1001GA C0G follows standard ITO-220AB single-diode layout (pin 1 anode, pin 2 cathode, tab cathode). Though electrically comparable, PCB layout change is required - verify pinout before substitution.
