Product details
Overview
STPR2030 from Diodes Incorporated is a 20A dual-leg super-fast rectifier diode rated for 300V peak reverse voltage, with 1.3V forward voltage at 10A/25°C, 35ns reverse recovery time, and 10μA reverse leakage at 300V/25°C, deployed in high-frequency DC-DC converters and SMPS secondary-side rectification.
For engineers reviewing the STPR2030 datasheet, STPR2030 pinout, STPR2030 application, or STPR2030 equivalent, key selection criteria include its TO220AB (Type WX) package thermal resistance (RθJC = 2°C/W), 125A non-repetitive surge rating, and low-junction-to-lead thermal resistance (RθJL = 1°C/W) for high-power density designs.
Technical Context
This dual-cathode common-anode configuration supports full-wave rectification in bridge or center-tap topologies. Its glass-passivated die construction ensures stable performance under thermal cycling and high dv/dt stress typical in switching power supplies.
The device operates across –55°C to +150°C junction temperature range and delivers 80pF typical junction capacitance at 4V reverse bias, enabling efficient operation above 100kHz switching frequencies without excessive capacitive losses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300 V - blocks up to 300V reverse voltage per leg without breakdown |
| IO (per leg) | 10 A - continuous average forward current per anode-cathode path at TC = 100°C |
| VF @ 10A/25°C | 1.30 V - forward conduction loss directly impacts efficiency and thermal design |
| tRR | 35 ns - enables high-frequency operation with minimal switching loss and EMI |
| IR @ 300V/25°C | 10 µA - low leakage preserves no-load efficiency and reduces standby power loss |
| RθJC | 2 °C/W - allows direct heatsink mounting for thermal management in compact power stages |
| IFSM | 125 A - withstands short-duration inrush and fault currents without failure |
Pinout & Package
STPR2030 uses the TO220AB (Type WX) package: insulated plastic case with three leads, common anode configuration, matte tin-plated leads solderable per MIL-STD-202 Method 208, UL 94V-0 rated molding compound, and approximate weight of 1.927 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input terminal for first rectifying leg | Connects to transformer secondary or input node in full-wave configuration |
| Anode (Lead 2) | Input terminal for second rectifying leg | Enables dual-leg synchronous or independent rectification paths |
| Cathode (Lead 3) | Common output node | Serves as shared DC output return for both legs; electrically tied internally |
Key Features
| Feature | Design Value |
|---|---|
| Super-fast switching (tRR = 35 ns) | Reduces turn-off loss and improves efficiency in >100 kHz SMPS designs |
| Glass-passivated die | Enhances reliability under humidity, thermal stress, and high dv/dt transients |
| Low RθJL = 1°C/W | Enables rapid heat transfer from junction to lead, supporting high-current pulse handling |
| RoHS 3 & "Green" compliant | Meets <900 ppm Br/Cl (<1500 ppm total), <1000 ppm Sb for automotive and industrial eco-regulations |
| 125A IFSM rating | Provides margin against startup surges and line transients without derating |
Applications
| Server PSU Secondary Rectification | Industrial DC-DC Converter Output Stage |
|---|---|
Use Scenario: High-efficiency 48V–12V isolated DC-DC conversion in 1U server power supplies. IC Role / Device Role / Timing Role: Dual-leg common-cathode rectifier replacing discrete diodes in synchronous rectifier auxiliary rails. Use Value: 35ns tRR minimizes switching loss at 300kHz operation, while 1.3V VF reduces conduction loss versus standard fast recovery diodes. | Use Scenario: 24V output stage in programmable logic controller (PLC) power modules. IC Role / Device Role / Timing Role: Full-wave rectifier in flyback or forward converter secondary, operating continuously at 85°C ambient. Use Value: RθJC = 2°C/W enables direct heatsink mounting without thermal interface pads, simplifying mechanical layout and improving long-term reliability. |

Use Value: –55°C to +150°C operating range ensures functionality across cold-start and under-hood thermal extremes without derating. |
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 (STMicroelectronics) | 300V VRRM, 20A IO, tRR = 45ns, VF = 1.35V @ 10A | Higher tRR increases switching loss at >200kHz; same TO220AC package | Prefer when lower cost is prioritized over ultra-fast recovery in ≤150kHz designs |
| DF2003S (ON Semiconductor) | 300V VRRM, 20A IO, tRR = 30ns, VF = 1.25V @ 10A, RθJC = 1.8°C/W | Marginally faster recovery and lower VF, but tighter thermal resistance tolerance | Select for highest efficiency in thermally constrained 200–500kHz applications where 0.05V VF reduction justifies sourcing change |
Compared with STTH2003D and DF2003S, STPR2030 offers balanced trade-offs: identical VRRM and IO, mid-range tRR (35ns), and superior thermal coupling (RθJL = 1°C/W) for robust pulse-current handling-making it optimal for industrial SMPS with mixed-frequency operation and thermal cycling demands.

FAQ
What is the maximum junction temperature for STPR2030?
The STPR2030 has a specified operating junction temperature range of –55°C to +150°C. This rating is validated per JEDEC standards and supported by its glass-passivated die construction and TO220AB thermal design, enabling reliable operation in harsh environments such as industrial motor drives and automotive under-hood applications.
Is STPR2030 suitable for synchronous rectification circuits?
No-STPR2030 is a passive super-fast rectifier diode, not a MOSFET-based synchronous rectifier. It lacks gate control and cannot be actively switched. However, it serves as a high-performance replacement for standard fast recovery diodes in quasi-resonant or hard-switched topologies where synchronous FETs are not used or feasible.
Does STPR2030 meet AEC-Q101 requirements for automotive use?
STPR2030 is not AEC-Q101 qualified. The datasheet explicitly states that automotive-grade versions require specific qualification (AEC-Q100/101/200), PPAP capability, and IATF 16949 manufacturing-none of which apply to the commercial-grade STPR2030. For automotive applications, contact Diodes Incorporated for qualified alternatives like the SBRT2030.
How does the TO220AB (Type WX) package differ from standard TO220AB?
The TO220AB (Type WX) variant features enhanced thermal performance: RθJC = 2°C/W and RθJL = 1°C/W, achieved via optimized internal leadframe geometry and die attach. It also uses halogen-free green molding compound (UL 94V-0) and matte tin plating meeting MIL-STD-202 solderability requirements-distinguishing it from legacy TO220AB variants with higher thermal resistance and non-green finishes.
