Product details
Overview
STPR2020 from Diodes Incorporated is a 20A super-fast rectifier diode in TO220AB package, rated for 200V peak reverse voltage, 10A average output current per leg (20A total), 1.1V forward voltage at 10A/25°C, and 30ns reverse recovery time. It serves as a primary output rectifier in high-frequency DC-DC converters and SMPS secondary-side rectification.
For engineers reviewing the STPR2020 datasheet, STPR2020 pinout, STPR2020 application, or STPR2020 equivalent, key selection criteria include its 30ns tRR, 1.1V VF at 10A/25°C, 125A non-repetitive surge rating, TO220AB thermal performance (RθJC = 2°C/W), and low 10µA IR at 200V/25°C.
Technical Context
This dual-leg super-fast rectifier uses glass-passivated silicon die to achieve fast switching with low stored charge. Its 30ns reverse recovery time and 95pF junction capacitance support operation up to several hundred kHz in hard-switched topologies.
The device operates across –55°C to +150°C junction temperature range and delivers 20A total average rectified current when case temperature is maintained at ≤110°C. Thermal resistance from junction to case is 2°C/W with fin-type heatsink mounting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - blocks up to 200V reverse voltage without breakdown |
| IO (per leg) | 10 A - supports 10A continuous DC output per anode-cathode path |
| VF @ 10A/25°C | 1.10 V - determines conduction loss and thermal dissipation in rectifier stage |
| tRR | 30 ns - enables efficient operation in high-frequency SMPS (>200 kHz) |
| IFSM | 125 A - withstands short-duration line surges or startup transients |
| RθJC | 2 °C/W - defines thermal path efficiency to heatsink under standard mounting |
| IR @ 200V/25°C | 10 µA - minimizes standby power loss in offline power supplies |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Input node for first rectifier leg | Accepts AC or switched input; paired with Cathode for unidirectional conduction |
| Cathode | Common output node | Shared cathode connection for both legs; electrically tied to metal tab |
| Anode 2 | Input node for second rectifier leg | Enables dual-leg configuration for center-tapped transformer or dual-output designs |
Key Features

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, 35ns tRR, TO247 package, higher RθJC (1.5°C/W) | Requires larger heatsink footprint; better surge rating (150A IFSM) | Preferred where higher surge immunity outweighs thermal density constraints |
| ESAD20-200 | 200V, 10A/leg, 32ns tRR, TO220AC package, single-anode configuration | Lacks dual-anode topology; no common-cathode option for center-tapped designs | Select only for single-output topologies requiring identical electrical specs |
Compared with STTH2002CW and ESAD20-200, the STPR2020 uniquely combines dual-anode/common-cathode topology, TO220AB's optimized thermal interface, and 30ns tRR-making it optimal for space-constrained, dual-output SMPS where layout simplicity and thermal efficiency are critical.

FAQ
What is the maximum junction temperature for continuous operation?
The STPR2020 has a specified operating junction temperature range of –55°C to +150°C. For reliable continuous operation, junction temperature must be maintained ≤150°C, typically achieved by limiting case temperature to ≤110°C using appropriate heatsinking per the derating curve in DS43818.
Is the metal tab electrically isolated or connected to a terminal?
The metal tab of the TO220AB package is electrically connected to the cathode terminal. This is confirmed in the mechanical data section and pin-out diagram of DS43818 Rev. 2–2, and requires proper insulation when mounted to grounded heatsinks.
Does STPR2020 meet AEC-Q101 for automotive use?
While STPR2020 is manufactured in IATF 16949-certified facilities and supports PPAP, Diodes states that automotive-qualified versions require explicit AEC-Q101 qualification and change control-available upon request. The commercial-grade STPR2020 is not pre-qualified to AEC-Q101 unless ordered under designated automotive part numbers.
How does the 30ns reverse recovery time impact EMI performance?
A 30ns tRR reduces high-frequency ringing during turn-off, lowering broadband EMI emissions in the 30–300 MHz range. Measured data in DS43818 shows reduced dv/dt overshoot versus slower rectifiers, easing compliance with CISPR-22 Class B conducted emission limits in compact power supplies.
