Product details
Overview
FFSP10120A from onsemi is a silicon carbide (SiC) Schottky diode rated for 1200 V peak repetitive reverse voltage and 10 A continuous forward current at case temperature < 148°C, with no reverse recovery current, positive temperature coefficient, and avalanche-rated energy of 100 mJ - deployed in high-efficiency solar inverters and UPS systems.
For engineers reviewing the FFSP10120A datasheet, pinout, applications, or equivalent options, key selection criteria include its 175°C max junction temperature, 0.89°C/W junction-to-case thermal resistance, 1.45–2.4 V forward voltage range across temperature, 200–400 nA reverse leakage at 1200 V, and TO-220-2L package compatibility with high-power switching topologies.
Technical Context
The FFSP10120A leverages wide-bandgap SiC material to eliminate reverse recovery charge and associated switching losses, enabling operation at higher frequencies than silicon diodes. Its unipolar conduction mechanism ensures temperature-independent switching behavior and stable forward voltage rise with junction temperature.
Designed for hard-switched and resonant power converters, the device supports fast turn-off under inductive loads with verified unclamped inductive switching (UIS) capability up to 100 mJ at 25°C, and exhibits low capacitive charge (62 nC at 800 V) and reduced capacitance drift over reverse voltage (47–612 pF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1200 V - supports DC-link voltages in 1000 V-class solar inverters and industrial UPS without derating |
| IF | 10 A continuous - delivers rated output current at TC < 148°C with standard heatsinking |
| VF @ 10 A, 25°C | 1.45–1.75 V - enables low conduction loss in boost and LLC rectification stages |
| IR @ 1200 V, 175°C | 400 nA - maintains minimal leakage during high-temperature operation in enclosed enclosures |
| RJC | 0.89 °C/W - allows direct thermal interface to heatsink with predictable junction temperature rise |
| EAS | 100 mJ - withstands single-pulse avalanche stress during transient overvoltage events |
| QC | 62 nC @ 800 V - reduces capacitive switching loss in high-frequency PFC and DC-DC stages |
Pinout & Package
FFSP10120A is housed in a TO-220-2L (Case 340BB) package with isolated tab, featuring two terminals: Pin 1 (cathode) and Pin 2 (anode). The metal tab is electrically connected to the cathode and serves as the primary thermal path.

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D10120A | Same 1200 V/10 A rating; 0.85°C/W RJC, slightly lower VF (1.35 V typ @ 10 A, 25°C); offered in TO-220-2L but with different marking and traceability | Identical use in solar inverters and UPS; minor thermal margin advantage in high-density layouts | Select C3D10120A if tighter thermal budget or legacy Wolfspeed supply chain alignment is required |
| STPSC10H12D | 1200 V/10 A; higher VF (1.8 V max @ 10 A, 25°C); RJC = 0.95°C/W; same TO-220-2L footprint | Valid for general-purpose SMPS and industrial drives, but less optimal for high-frequency PFC due to higher conduction loss | Prefer STPSC10H12D where cost sensitivity outweighs efficiency targets and layout allows extra thermal margin |
Compared with C3D10120A and STPSC10H12D, the FFSP10120A offers balanced trade-offs: superior avalanche ruggedness (100 mJ vs. 75 mJ for STPSC10H12D), better thermal resistance than ST's part, and broader industry validation in solar and UPS OEM designs - making it the default choice for new high-reliability 1200 V SiC rectifier deployments.

FAQ
What is the maximum allowable case temperature for continuous operation of the FFSP10120A?
The FFSP10120A supports continuous forward current of 10 A only when case temperature remains below 148°C, as specified in the Absolute Maximum Ratings table. Exceeding this limit risks thermal runaway due to increased leakage current and reduced avalanche margin. Derating curves in Figure 4 confirm usable current drops to ~5.5 A at 150°C case temperature. Always verify thermal design using the measured RJC of 0.89°C/W and ambient conditions.
Does the FFSP10120A require a gate driver or control signal?
No - the FFSP10120A is a passive two-terminal power diode with no gate or control input. It conducts forward current when anode voltage exceeds cathode voltage by its forward voltage drop (VF), and blocks reverse voltage up to 1200 V. Unlike MOSFETs or IGBTs, it requires no driver circuitry, simplifying layout and reducing BOM count in rectifier and freewheeling roles.
Can FFSP10120A be paralleled with other SiC diodes for higher current handling?
Yes - the FFSP10120A features a positive temperature coefficient of forward voltage, enabling stable current sharing when paralleled. To ensure balance, use matched devices, symmetrical PCB layout with equal trace lengths and thermal paths, and common heatsinking. Avoid mixing FFSP10120A with dissimilar SiC diodes (e.g., different VF or RJC) unless validated per application note AND9741/D.
What is the typical reverse leakage current of FFSP10120A at 1200 V and 125°C?
Per the Electrical Characteristics table, the FFSP10120A exhibits a maximum reverse current of 300 nA at VR = 1200 V and TC = 125°C. This ultra-low leakage - characteristic of SiC Schottky technology - ensures minimal standby power loss and stable blocking performance in high-temperature environments such as enclosed solar inverter cabinets.
Is FFSP10120A suitable for use in automotive traction inverters?
No - the FFSP10120A is not qualified to AEC-Q101 or AQG-324 standards and lacks automotive-grade qualification documentation. While its 175°C rating and avalanche capability may appear suitable, onsemi positions this device for industrial, solar, and UPS applications only. For automotive traction, refer to onsemi's AEC-Q101-qualified NVHLxxx series or Wolfspeed's C3Mxxx automotive-grade SiC diodes.
