Product details
Overview
STPF1030 from Diodes Incorporated is a 10A dual-leg super-fast rectifier diode rated for 300V peak reverse voltage, with 1.30V forward voltage at 5A/25°C, 10μA reverse leakage at 300V/25°C, and 35ns reverse recovery time-designed for high-frequency DC-DC converters in server power supplies.
For engineers reviewing the STPF1030 datasheet, STPF1030 pinout, STPF1030 application, or STPF1030 equivalent, key selection criteria include its ITO220AB (Type WX) package thermal resistance (5°C/W), dual-leg 5A-per-leg average current rating at Tc=90°C, and low capacitance (30–50pF at 4V/1MHz) critical for EMI-sensitive SMPS designs.
Technical Context
This dual-cathode common-anode super-fast rectifier integrates two independent 5A legs in a single ITO220AB (Type WX) thermally optimized package. Its glass-passivated silicon die enables stable operation from −55°C to +150°C junction temperature with 80A non-repetitive surge capability.
The device delivers fast switching via low stored charge (Qrr not specified but tRR = 35ns confirmed), low VF drift across temperature (1.20V @ 5A/125°C), and minimal reverse recovery tail current-making it suitable for synchronous rectification replacement in isolated flyback and forward converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300 V - blocks up to 300V repetitive reverse voltage without breakdown, enabling use in 200–250V DC bus applications |
| IO (per leg) | 5 A @ Tc = 90°C - supports continuous 5A output per cathode leg with heatsink mounting |
| VF | 1.30 V @ 5A, 25°C - reduces conduction loss vs. standard fast rectifiers, improving efficiency in 100–500kHz converters |
| tRR | 35 ns - minimizes switching loss and EMI generation during turn-off transitions |
| IR | 10 μA @ 300V, 25°C - ensures low standby power loss in high-impedance hold-up circuits |
| CT | 30–50 pF @ 4V, 1MHz - limits capacitive coupling noise in high-dv/dt gate-drive or feedback paths |
| RθJC | 5 °C/W - enables direct thermal coupling to aluminum heatsinks for sustained 10A total output |
Pinout & Package
Package: ITO220AB (Type WX), molded green plastic (UL 94V-0), matte tin-plated leads, 1.558g weight. Mounting requires mechanical screw-down to heatsink via central tab (anode connection).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Tab) | Common anode terminal | Electrically and thermally connected to metal tab; must be isolated from chassis unless circuit ground referenced |
| Cathode 1 (Lead 1) | First rectifying leg cathode | Output node for first 5A leg; used in dual-output or interleaved converter phases |
| Cathode 2 (Lead 2) | Second rectifying leg cathode | Independent output node for second 5A leg; enables shared-anode dual-channel rectification |
Key Features
| Feature | Design Value |
|---|---|
| Super-fast switching (tRR = 35 ns) | Reduces turn-off energy loss and high-frequency ringing in >200kHz SMPS topologies |
| Glass passivated die construction | Ensures long-term reliability under humidity and thermal cycling stress in industrial environments |
| Low forward voltage (1.30 V @ 5A) | Lowers I²R conduction loss by ~15% vs. comparable 1.5V VF rectifiers at same current |
| RoHS-compliant, halogen-free "Green" compound | Meets IPC-1752A material declaration requirements for automotive and medical OEMs |
| 100% lead finish solderability (MIL-STD-202) | Guarantees robust reflow and wave solder joint integrity on production PCBs |
Applications
| Server AC-DC Power Supplies | Industrial DC-DC Converters |

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 | 600V VRRM, 1.75V VF @ 5A, 50ns tRR, TO-220AC package | Higher voltage rating but slower switching and higher conduction loss | Select when 600V blocking is required and 35ns tRR is not critical |
| DF10S | 1000V VRRM, 1.15V VF @ 1A, 35ns tRR, SMD DPAK package, 1A rating | Lower current rating, surface-mount only, unsuitable for >2A continuous loads | Choose only for low-power, space-constrained designs where 10A capability is unnecessary |
Compared with STTH10R06DJF and DF10S, STPF1030 uniquely balances 300V rating, 10A total current, 35ns speed, and through-hole ITO220AB thermal performance-making it optimal for medium-power, heatsink-mounted SMPS where efficiency, EMI, and thermal management are co-constrained.

FAQ
What is the maximum junction temperature and thermal resistance of STPF1030?
The STPF1030 has a maximum junction temperature of +150°C and a typical thermal resistance of 5°C/W from junction to case (RθJC). This value assumes mounting on a 100.64mm × 75.2mm × 26.83mm aluminum heatsink per JESD-51 test conditions. Derating curves in the datasheet confirm 5A per leg is sustainable at Tc = 90°C.
Is STPF1030 qualified for automotive applications?
STPF1030 is not pre-qualified to AEC-Q101, but Diodes Incorporated offers automotive-grade variants of this platform (e.g., STPF1030Q) with PPAP documentation, IATF 16949 manufacturing, and full change control. Standard STPF1030 may be used in non-safety-critical automotive subsystems pending customer qualification.
How does the dual-leg configuration affect PCB layout and thermal design?
The dual-cathode configuration allows independent routing of each 5A output leg, reducing current loop area and EMI. The common anode tab must be mounted directly to a heatsink using a thermal pad and screw; isolation washers are required if the tab is not electrically tied to system ground. Thermal vias under cathode pads improve lateral heat spreading.
What is the reverse recovery charge (Qrr) specification for STPF1030?
The datasheet does not specify Qrr directly, but the measured reverse recovery time (tRR) is 35ns under IF = 0.5A, IR = 1.0A, and IRR = 0.25A conditions. Designers should use tRR and the provided VF/IR/CT parameters for loss estimation; Qrr can be approximated from oscilloscope-based measurement in actual circuit conditions.
