Product details
Overview
STPS2030 from Diodes Incorporated is a 300 V, 20 A dual common-cathode super-fast rectifier in ITO-220AB package, designed for high-frequency switching power conversion with 1.3 V forward voltage at 10 A and 35 ns reverse recovery time. It serves as the output rectifier in SMPS and DC-DC converters operating up to several hundred kHz.
For engineers reviewing the STPS2030 datasheet, STPS2030 pinout, STPS2030 application, or STPS2030 equivalent, key selection criteria include peak repetitive reverse voltage (300 V), average output current per leg (10 A), thermal resistance junction-to-case (3 °C/W), and low reverse leakage (10 µA at 300 V, 25°C).
Technical Context
This dual-leg super-fast rectifier integrates two independent 300 V/10 A diode elements sharing a common cathode terminal, enabling synchronous or interleaved output rectification topologies. Its glass-passivated die construction ensures stable performance under thermal cycling and high dv/dt stress.
The device achieves fast switching via optimized carrier lifetime control, delivering tRR = 35 ns under IF = 0.5 A / IR = 1.0 A conditions, while maintaining low VF (1.30 V @ 10 A, 25°C) and low CT (80 pF @ 4 V, 1 MHz) for minimal switching loss and EMI generation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300 V - supports DC bus voltages up to 212 V RMS or 300 V peak without breakdown |
| IO (per leg) | 10 A @ TC = 75°C - defines continuous conduction capability per anode path with heatsink |
| VF | 1.30 V @ 10 A, 25°C - determines conduction loss and thermal load in high-current output stages |
| tRR | 35 ns - enables operation in 200–500 kHz SMPS with reduced switching loss and ringing |
| IR | 10 µA @ 300 V, 25°C - minimizes standby power loss and improves light-load efficiency |
| RθJC | 3 °C/W - allows direct mounting to heatsink for thermal management of 20 A total output current |
| IFSM | 125 A @ 8.3 ms - withstands inrush and transient overcurrent events in power supplies |

Applications
| Server PSU Output Rectification | Industrial DC-DC Converter |
|---|---|
Use Scenario: 12 V/20 A output stage in 80 PLUS Titanium server power supply using active clamp forward topology. IC Role / Device Role / Timing Role: Dual common-cathode output rectifier replacing two discrete diodes to reduce layout area and parasitic inductance. Use Value: 1.3 V VF lowers conduction loss by ~15% vs. standard FRD alternatives, improving full-load efficiency by 0.4–0.6%. | Use Scenario: 24 V regulated output in programmable logic controller (PLC) power module with wide input range (90–264 V AC). IC Role / Device Role / Timing Role: High-reliability secondary-side rectifier handling 10 A per leg with surge immunity up to 125 A. Use Value: 35 ns tRR suppresses voltage overshoot during MOSFET turn-on, reducing snubber losses and EMI filter size. |
| Telecom 48 V Rectifier Module | EV On-Board Charger Auxiliary Supply |
Use Scenario: +48 V telecom rectifier board requiring high power density and -40°C to +105°C ambient operation. IC Role / Device Role / Timing Role: Dual-leg rectifier feeding parallel buck regulators; leverages common-cathode configuration for shared output filtering. Use Value: 10 µA IR at 300 V ensures <1 mW standby dissipation, critical for always-on network infrastructure. | Use Scenario: 12 V auxiliary supply in 6.6 kW OBC, powered from 400 V DC link via flyback converter. IC Role / Device Role / Timing Role: Fast-recovery rectifier on secondary side operating at 100–250 kHz with tight thermal constraints. Use Value: RθJC = 3 °C/W enables direct tab-mounting to aluminum chassis, eliminating need for additional thermal interface material. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2003D | 300 V, 20 A single-die TO-220AC; no common-cathode dual configuration | Requires two devices for dual-leg topology; higher PCB area and interconnect inductance | Prefer when layout uses discrete anodes and thermal isolation between legs is required |
| VS-20EWH03-M3 | 300 V, 20 A dual common-cathode in TO-247AC; RθJC = 2.5 °C/W, tRR = 30 ns | Higher cost and larger footprint; better thermal performance but over-specified for many ITO-220AB applications | Choose only when junction temperature must stay below 125°C under 20 A continuous with minimal heatsink |
Compared with STTH2003D and VS-20EWH03-M3, STPS2030 uniquely balances dual-leg integration, ITO-220AB mountability, and 35 ns recovery in a cost-optimized industrial-grade package-making it optimal for space-constrained 10–20 A SMPS where common-cathode topology reduces component count and layout complexity.

FAQ
What is the maximum junction temperature for continuous operation?
The STPS2030 has an operating junction temperature range of –55°C to +150°C. For reliable continuous operation at full 20 A total current, thermal design must ensure TJ remains ≤150°C, typically requiring heatsink mounting and airflow or derating above TC = 75°C per the forward current derating curve.
Can STPS2030 replace a single 20 A standard recovery diode?
No-it is a dual-leg device with two independent anodes and one common cathode. Replacing a single-diode solution requires verifying circuit topology compatibility; using only one anode leg wastes half the device and may cause imbalance in thermal or electrical stress distribution.
Is STPS2030 qualified for automotive applications?
STPS2030 is not AEC-Q101 qualified. Diodes Incorporated offers automotive-grade variants (e.g., STPS2030AY) with PPAP support and IATF 16949 manufacturing, but this standard part is intended for industrial, computing, and telecom use only.
How is polarity identified on the ITO-220AB package?
Polarity is marked on the top surface: the cathode (common terminal) is the metal tab, and the two anodes are leads 1 and 2. The device marking "STPS2030" and date code (YYWW) appear adjacent to lead 1; the tab is electrically connected to the cathode and must be insulated from other potentials unless serving as the output reference.
