Product details
Overview
STPR1030 from Diodes Incorporated is a 10A dual-leg super-fast rectifier diode in TO220AB (Type WX) package, rated for 300V peak reverse voltage, 1.3V forward voltage at 5A/25°C, and 35ns reverse recovery time. It delivers low conduction loss and fast switching for high-frequency DC-DC converters and SMPS secondary-side rectification.
For engineers reviewing the STPR1030 datasheet, STPR1030 pinout, STPR1030 application, or STPR1030 equivalent, key selection criteria include its 300V VRRM rating, 35ns tRR, 10µA IR at 300V/25°C, thermal resistance of 4.2°C/W (Junction-to-Case), and TO220AB mechanical compatibility with standard heatsinks.
Technical Context
The STPR1030 integrates two independent super-fast rectifying legs in a single TO220AB package, each rated for 5A average output current and sharing a common cathode configuration. Its glass-passivated die construction ensures stable performance under thermal cycling and high dv/dt conditions typical in flyback and forward converter topologies.
With a typical junction-to-case thermal resistance of 4.2°C/W and maximum operating temperature of +150°C, it supports continuous operation at elevated ambient temperatures when mounted on a 50mm × 50mm × 2mm copper heatsink. The 35ns reverse recovery time enables efficient operation above 100kHz switching frequencies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300 V - Withstands peak reverse voltage up to 300V without breakdown, suitable for 200–240VAC input-derived DC bus applications. |
| IO (per leg) | 5 A - Sustains 5A average forward current per anode leg at TA = +25°C, enabling 10A total dual-leg output capability. |
| VF @ 5A/25°C | 1.30 V - Low conduction loss reduces power dissipation and improves efficiency in high-current rectification stages. |
| tRR | 35 ns - Enables clean commutation in high-frequency SMPS (>100 kHz), minimizing switching losses and EMI generation. |
| IR @ 300V/25°C | 10 µA - Ultra-low leakage preserves efficiency in standby and light-load conditions, critical for energy-compliant designs. |
| RθJC | 4.2 °C/W - Allows predictable thermal design with standard TO220 heatsinking; 21W max power dissipation at ΔT = 88.2°C. |
| Package | TO220AB (Type WX) - Industry-standard through-hole package with isolated mounting tab, compatible with legacy PCB footprints and heatsink clamps. |
Pinout & Package
TO220AB (Type WX) package with three terminals: Anode 1 (Pin 1), Anode 2 (Pin 2), Cathode (Pin 3). Mounting tab is electrically connected to Cathode (Pin 3) and serves as primary thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode 1) | Input terminal for first rectifying leg | Connects to transformer secondary or switching node; carries up to 5A average forward current. |
| Pin 2 (Anode 2) | Input terminal for second rectifying leg | Independent anode path enables dual-output or interleaved rectification without external parallel diodes. |
| Pin 3 / Tab (Cathode) | Common output terminal for both legs | Electrically tied to mounting tab; must be thermally coupled to heatsink and electrically referenced to system ground or output rail. |
Key Features
| Feature | Design Value |
|---|---|
| Super-fast switching (tRR = 35 ns) | Reduces turn-off losses and ringing in high-frequency converters, supporting >100 kHz operation without snubber optimization. |
| Glass-passivated die construction | Enhances long-term reliability under humidity, thermal stress, and high dv/dt transients in industrial and automotive-qualified environments. |
| Common-cathode dual-leg topology | Eliminates need for external paralleling; simplifies layout, reduces parasitic inductance, and improves current sharing accuracy. |
| RoHS-compliant, halogen- and antimony-free | Meets IEC 61249-2-21 and JEDEC J-STD-70B requirements for green electronics manufacturing and end-of-life disposal. |
Applications
| Server Power Supply | Laptop AC-DC Adapter |

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, 1.7V VF @ 10A, 60ns tRR - higher voltage rating but slower recovery and higher VF. | Better suited for 400VDC bus applications; less optimal for high-frequency, low-VF designs below 300V. | Select when system requires >300V blocking margin and can tolerate higher conduction loss. |
| ES1J-M3/84A | 600V VRRM, 1A IO, 1.7V VF @ 1A, 35ns tRR - same tRR but 1/10th current rating and TO-220AC package (non-isolated tab). | Only viable for low-power auxiliary rails; unsuitable for main output rectification due to current limitation. | Use only for signal-level or bias supply rectification where isolation and thermal mass are not required. |
Compared with STTH10R06DJF and ES1J-M3/84A, the STPR1030 uniquely balances 300V blocking, 10A dual-leg current, 35ns speed, and TO220AB thermal performance-making it optimal for cost-sensitive, high-efficiency 100–300W SMPS where both conduction and switching losses must be minimized.

FAQ
Is the STPR1030 pin-compatible with standard TO220AB rectifiers?
Yes - STPR1030 uses the industry-standard TO220AB (Type WX) footprint with Pin 1 (Anode 1), Pin 2 (Anode 2), and Pin 3/Cathode Tab. Its pinout matches common dual-anode rectifiers like BYV26E and STTH10R06DJF, though electrical ratings differ.
What is the maximum allowable case temperature during continuous operation?
The STPR1030 has a maximum junction temperature of +150°C and a typical RθJC of 4.2°C/W. With a 50mm × 50mm × 2mm copper heatsink, sustained case temperatures up to +95°C are achievable at full 10A load, assuming ambient ≤ +50°C and adequate airflow.
Does the mounting tab require electrical isolation from the heatsink?
No - the mounting tab is internally connected to the cathode (Pin 3) and is intended to be electrically tied to the output rail or system ground. If isolation is required, use insulating hardware (e.g., mica washer + nylon screw) and verify creepage/clearance compliance per safety standards.
Can STPR1030 replace a single 10A standard recovery diode in a bridge configuration?
No - STPR1030 is a dual-anode, common-cathode device, not a bridge rectifier. It replaces two discrete anodes feeding one cathode, such as in center-tapped transformer outputs or dual-winding configurations. For full-wave bridge replacement, four diodes or a dedicated bridge like GBU10K are required.
