Product details
Overview
STPR1020 from Diodes Incorporated is a 10A dual-leg super-fast rectifier diode rated for 200V peak reverse voltage, with 1.1V max forward voltage at 5A/25°C, 10μA max reverse leakage at 200V/25°C, and 22ns typical reverse recovery time - deployed in high-frequency DC-DC converters and SMPS output stages.
For engineers reviewing the STPR1020 datasheet, STPR1020 pinout, STPR1020 application, or STPR1020 equivalent, key selection criteria include its TO220AB (Type WX) package thermal resistance (RθJC = 4.2°C/W), 80A non-repetitive surge rating, and low capacitance (30–50pF at 4V/1MHz) critical for EMI-sensitive switching topologies.
Technical Context
This dual-cathode common-anode configuration supports full-wave rectification in bridge or center-tap topologies. Its glass-passivated silicon die ensures stable reverse characteristics across -55°C to +150°C operating range and enables reliable operation under repetitive surge stress up to 80A (8.3ms half-sine).
The device delivers fast switching via optimized carrier lifetime control, achieving tRR ≤30ns while maintaining low VF (0.80–1.25V across 5–10A and 25–125°C), balancing conduction loss and turn-off loss in 100kHz–1MHz power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - blocks up to 200V reverse voltage per leg without breakdown |
| IO (per leg) | 5 A - continuous DC current rating per anode-cathode path at 25°C ambient |
| VF @ 5A/25°C | 1.10 V max - limits conduction loss to ≤5.5W per leg at rated current |
| tRR | 22 ns typ - enables efficient operation in >500kHz switching converters |
| IR @ 200V/25°C | 10 μA max - minimizes standby power loss in high-impedance hold-up circuits |
| RθJC | 4.2 °C/W - allows ~19W power dissipation with 80°C case-to-junction rise at heatsink mounting |
| CT @ 4V/1MHz | 30–50 pF - reduces high-frequency ringing and EMI generation in snubberless designs |
Pinout & Package
Package: TO220AB (Type WX), molded plastic with matte tin-plated leads, UL 94V-0 rated, 2.24g weight. Mounting tab is electrically connected to the common anode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab (center) | Common Anode | Electrically tied to both internal anodes; requires insulated mounting if referenced to non-ground potential |
| Lead 1 (left) | Cathode 1 | Output path for first rectifying leg; used in dual-output or interleaved configurations |
| Lead 2 (right) | Cathode 2 | Independent cathode terminal enabling separate filtering or sensing per leg |
Key Features
| Feature | Design Value |
|---|---|
| Super-fast switching (tRR ≤30ns) | Reduces turn-off losses and EMI in high-frequency SMPS without requiring external snubbers |
| Glass passivated die | Ensures long-term stability of reverse leakage and breakdown voltage under humidity and thermal cycling |
| TO220AB thermal performance (RθJC = 4.2°C/W) | Supports 10A total output with standard copper heatsink (50×50×2mm), eliminating need for forced air |
| Low VF / low IR trade-off optimization | Delivers 0.80V @ 5A/125°C and only 250μA IR @ 200V/100°C - critical for high-efficiency, high-temp industrial PSUs |
| RoHS 3 & "Green" compliant (Br+Cl <1500ppm, Sb <1000ppm) | Meets global environmental regulations without compromising thermal or electrical performance |
Applications
| Server Power Supply | Industrial DC-DC Converter |
|---|---|
Use Scenario: Secondary-side synchronous rectification replacement in 48V input, 12V/20A output telecom PSU. IC Role / Device Role / Timing Role: Dual-leg super-fast rectifier providing isolated full-wave output with minimal conduction loss. Use Value: Achieves >93% efficiency at full load by maintaining VF ≤0.92V @ 5A/125°C and limiting tRR-induced switching loss. | Use Scenario: Output rectification in 24V input, ±15V dual-rail PLC power module. IC Role / Device Role / Timing Role: Common-anode dual-cathode configuration enables independent filtering of positive/negative rails. Use Value: Low 10μA IR prevents cross-rail leakage; 22ns tRR suppresses high-frequency noise coupling between rails. |
| LED Driver Power Stage | Automotive Infotainment PSU |
Use Scenario: High-current rectification in constant-current LED driver with 200kHz flyback topology. IC Role / Device Role / Timing Role: Primary output rectifier handling pulsed 10A peak current with minimal voltage overshoot. Use Value: 80A IFSM rating withstands startup surges; 50pF CT avoids resonance with transformer leakage inductance. | Use Scenario: 12V-to-5V/3.3V buck-derived auxiliary supply in head unit with wide ambient (-40°C to +105°C). IC Role / Device Role / Timing Role: Input-stage rectifier conditioning unregulated battery feed before DC-DC regulation. Use Value: Stable V(BR)R ≥200V and RθJC = 4.2°C/W ensure reliability across automotive temperature 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 |
|---|---|---|---|
| STTH10R06DJF | 600V VRRM, 10A IO, tRR = 35ns, VF = 1.7V @ 10A/25°C | Higher voltage rating but higher VF and slower recovery - suited for PFC front-end, not secondary-side | Select when system requires >200V blocking; avoid where low conduction loss is prioritized |
| ES1J | 600V VRRM, 1A IO, tRR = 35ns, VF = 1.7V @ 1A/25°C | Single-leg, lower current, smaller DO-41 package - insufficient for 10A total output | Only viable for signal-level or low-power auxiliary rails; not a functional substitute for STPR1020's dual-leg 10A capability |
Compared with STTH10R06DJF and ES1J, the STPR1020 uniquely balances 200V blocking, dual-leg 10A current handling, sub-30ns recovery, and <1.1V forward drop - making it optimal for high-density, high-efficiency secondary-side rectification where thermal and EMI constraints are tight.

FAQ
Is the STPR1020 pin-compatible with standard TO220AB rectifiers like BYV26E?
No. The STPR1020 uses a common-anode dual-cathode configuration (Tab = Anode, Lead 1 = Cathode 1, Lead 2 = Cathode 2), whereas BYV26E is single-diode TO220AB with Tab = Cathode. Direct substitution would reverse polarity and cause circuit failure.
What is the maximum allowable junction temperature during continuous operation?
The STPR1020 has a rated operating junction temperature range of -55°C to +150°C. For continuous 10A total output, junction temperature must be limited to ≤150°C using appropriate heatsinking - verified by TJ = TC + (Ptot × RθJC), where Ptot ≈ 10W at 1.0VF and RθJC = 4.2°C/W.
Does the STPR1020 meet AEC-Q101 for automotive use?
No. The STPR1020 is qualified for commercial temperature range only (-55°C to +150°C ambient). Diodes offers AEC-Q101-qualified equivalents (e.g., SBRT10U200CT) with PPAP documentation and IATF 16949 manufacturing - contact Diodes directly for automotive-grade variants.
Can the STPR1020 be used in parallel for higher current capacity?
Not recommended without individual current-sharing resistors. The device lacks matched VF binning, and thermal coupling between paralleled units in TO220AB packages is poor - leading to current imbalance and premature failure of the hotter unit. Use a higher-rated single device (e.g., STPR2020) instead.
