Product details
Overview
STPS2020 from Diodes Incorporated is a 20A dual common-cathode super-fast rectifier diode rated for 200V peak reverse voltage, with 1.1V forward voltage at 10A/25°C and 30ns reverse recovery time, designed for high-frequency DC-DC converters and switched-mode power supplies where low conduction loss and fast switching are critical.
For engineers reviewing the STPS2020 datasheet, STPS2020 pinout, STPS2020 application, or STPS2020 equivalent, key selection criteria include its ITO220AB package thermal resistance (RθJC = 3°C/W), 125A non-repetitive surge rating, dual-leg configuration, and low 10µA reverse leakage at 200V/25°C - all essential for reliable high-power rectification in compact industrial and computing PSUs.
Technical Context
The STPS2020 integrates two independent super-fast silicon PN junctions in a single ITO220AB thermally optimized package, sharing a common cathode terminal. Its glass-passivated die construction ensures stable performance under thermal cycling and high dv/dt stress typical in flyback and LLC resonant topologies.
It operates across -55°C to +150°C junction temperature range with RθJC = 3°C/W and RθJL = 4°C/W, enabling direct mounting to heatsinks without isolation pads. The 93pF typical junction capacitance at 4V/1MHz supports efficient high-frequency operation up to several hundred kHz.
Key Specifications

| IO (per leg) | 10 A - Continuous average output current per diode leg at TC = +90°C, supporting 20A total dual-leg output |
| VF | 1.10 V @ 10A/25°C - Low conduction loss reduces power dissipation by ~11% vs. standard fast rectifiers at same current |
| tRR | 30 ns - Enables efficient operation in >200kHz switching converters without excessive switching loss or EMI |
| IR | 10 µA @ 200V/25°C - Minimizes standby power loss in energy-efficient adapters and server PSUs meeting Level VI standards |
| RθJC | 3 °C/W - Allows direct heatsink mounting for thermal management in space-constrained 1U server power modules |
| IFSM | 125 A @ 8.3ms - Withstands inrush surges during cold-start of industrial motor drives and telecom rectifiers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2002CW | 200V, 10A/leg, tRR = 35ns, VF = 1.25V @ 10A - higher forward drop and slower recovery | Higher conduction loss limits use in >96% efficiency designs; suitable for cost-sensitive industrial PSUs with <200kHz switching | Select when lower BOM cost outweighs 0.15V VF penalty and thermal margin is ample |
| VS-20CPH02-M3 | 200V, 20A total (single die), tRR = 25ns, VF = 0.95V @ 10A - faster, lower VF, but single-anode configuration | Lacks dual-anode flexibility; requires redesign of cathode routing and heatsink layout for common-cathode topology | Prefer for new designs prioritizing efficiency; avoid if reusing existing STPS2020 PCB footprint and thermal interface |
Compared with STTH2002CW and VS-20CPH02-M3, the STPS2020 uniquely balances 30ns recovery, 1.1V VF, and dual-anode/common-cathode pinout - making it optimal for drop-in upgrades in legacy SMPS designs requiring minimal layout change while gaining measurable efficiency improvement.

FAQ
Is STPS2020 suitable for synchronous rectification replacement?
Yes - its 30ns reverse recovery time and 1.1V forward voltage at 10A enable efficient replacement of Schottky diodes in 100–300kHz SMPS designs. Unlike Schottkys, it sustains 200V reverse blocking without thermal runaway, making it ideal for 48V–400V bus applications where Schottky voltage limits cause derating.
What is the maximum continuous current per leg at 100°C case temperature?
At TC = +100°C, the STPS2020's average rectified output current per leg is derated to approximately 7.2A, based on its forward current derating curve (Figure 1 in DS43761). This ensures safe operation within thermal limits without exceeding 150°C junction temperature under worst-case convection conditions.
Does STPS2020 require thermal interface material when mounted to a heatsink?
No - the ITO220AB package's metal tab is designed for direct mechanical and thermal contact with the heatsink surface. However, electrical isolation (e.g., mica washer or silicone pad) is required unless the heatsink is floating or system-ground referenced, as the tab connects to both anodes.
Can STPS2020 be used in automotive applications?
Yes - while the base STPS2020 is not AEC-Q101 qualified, Diodes offers automotive-grade variants (e.g., STPS2020H) with PPAP documentation, IATF 16949 manufacturing, and extended test coverage. Standard STPS2020 may be used in non-safety-critical automotive subsystems pending customer qualification.
