Product details
Overview
SBR20A300CTFP from Diodes Incorporated is a 20A dual common-cathode Super Barrier Rectifier rated for 300V peak repetitive reverse voltage, with maximum forward voltage drop of 0.92V at 10A and 25°C, leakage current ≤100µA at 300V/25°C, and reverse recovery time of 45ns - used as polarity protection, boost, blocking, and recirculating diodes in DC-DC converters and industrial power supplies.
For engineers reviewing the SBR20A300CTFP datasheet, SBR20A300CTFP pinout, SBR20A300CTFP application, or SBR20A300CTFP equivalent, key selection criteria include its ITO-220AB package thermal resistance (RθJC = 4°C/W), low VF stability up to +125°C, 2000V isolation rating between terminal and heatsink, and AEC-Q101 readiness for automotive-grade power conversion designs.
Technical Context
This dual-diode rectifier integrates two independent Super Barrier Rectifier chips in a single ITO-220AB package with common cathode configuration, enabling synchronous rectification or dual-path DC output. Its patented barrier structure delivers lower forward voltage than standard Schottky diodes while maintaining superior high-temperature leakage performance.
The device operates across -65°C to +175°C junction temperature range, supports non-repetitive surge current up to 180A (8.3ms half-sine), and is characterized for both resistive and inductive loads at 60Hz - with capacitance-load derating required per specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300 V - Maximum peak repetitive reverse voltage before breakdown; defines safe blocking capability in 24–48V bus systems. |
| IO (per leg) | 10 A - Average rectified current per anode leg at TA=25°C; total device rating is 20A with shared cathode. |
| VF MAX | 0.92 V @ IF=10A, TJ=25°C - Low conduction loss enables >95% efficiency in 12V–48V buck/boost stages. |
| IR MAX | 100 µA @ VR=300V, TJ=25°C - Ultra-low leakage preserves standby power in always-on industrial controllers. |
| Trr | 45 ns - Fast switching minimizes switching losses and EMI in high-frequency SMPS (>100kHz). |
| RθJC | 4 °C/W - Thermal resistance from junction to case in ITO-220AB package; enables 10W dissipation with 40°C rise over heatsink. |
| VAC (Isolation) | 2000 V - Dielectric strength between terminal and heatsink; satisfies reinforced insulation requirements for Class I equipment. |
Pinout & Package
Package: ITO-220AB - insulated TO-220 variant with plastic body, matte tin-plated copper leadframe, UL 94V-0 mold compound, and 2.0g mass. Features electrically isolated tab for direct heatsink mounting without insulator.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Lead 1) | Input path for first rectifier leg | Accepts AC or pulsating DC input; connects to transformer secondary or switch node in flyback topology. |
| Anode 2 (Lead 2) | Input path for second rectifier leg | Enables dual-output or interleaved operation; shares cathode for compact layout in dual-rail supplies. |
| Cathode (Tab) | Common output node | Electrically isolated metal tab serves as high-current return path; must be mounted to heatsink for thermal management. |
Key Features
| Feature | Design Value |
|---|---|
| Patented Super Barrier technology | Combines Schottky-like VF with PN-junction leakage performance - achieves 0.78V VF at 20A/25°C and <1mA IR at 300V/125°C. |
| ITO-220AB insulation | 2000V AC isolation between tab and leads - eliminates need for thermal pad insulators in safety-critical 24V/48V industrial systems. |
| High-temperature stability | VF increases only 0.14V from 25°C to 125°C at 10A - maintains regulation accuracy in enclosed enclosures without forced air. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current Super Barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-20CPH03-M3 | Same 300V/20A rating but TO-247 package; RθJC = 1.5°C/W; VF = 0.87V @ 10A/25°C. | Higher thermal performance but requires larger footprint and insulated mounting hardware. | Select when junction temperature must stay below 125°C under continuous 20A load with limited heatsink area. |
| ON Semiconductor MUR2030CT | Ultrafast recovery rectifier (Trr = 60ns); VF = 1.15V @ 10A/25°C; no isolation rating. | Lacks 2000V isolation and exhibits higher conduction loss - unsuitable for safety-isolated designs. | Choose only for cost-sensitive non-isolated applications where leakage <100µA at 125°C is not required. |
Compared with VS-20CPH03-M3, SBR20A300CTFP trades 2.5°C/W higher thermal resistance for ITO-220AB's integrated isolation and smaller board footprint; versus MUR2030CT, it delivers 23% lower conduction loss and certified isolation - critical for industrial safety compliance.

FAQ
What is the maximum junction temperature for continuous operation?
The SBR20A300CTFP is rated for continuous operation from -65°C to +175°C junction temperature. At ambient temperatures above 100°C, derating applies: average forward current drops linearly from 10A at 25°C to 0A at 175°C, per Figure 4 in DS30993 Rev. 10-2.
Can SBR20A300CTFP replace standard Schottky diodes in existing designs?
Yes - with verification of thermal and electrical margins. Its 0.92V VF at 10A/25°C is comparable to Schottkys, but its superior high-temperature leakage (<1mA at 125°C) and 300V rating allow direct substitution in 24V–48V systems where standard Schottkys fail due to thermal runaway or voltage overstress.
Does the ITO-220AB package require thermal interface material?
No - the ITO-220AB's insulated tab is rated for 2000V AC isolation and designed for direct metal-to-metal contact with heatsinks. Use thermally conductive grease or phase-change pads only if surface flatness or mounting pressure is insufficient to ensure low thermal resistance; mechanical clamping force ≥10 lbf recommended.
Is SBR20A300CTFP qualified for automotive applications?
While not pre-qualified to AEC-Q101, Diodes states that automotive-grade versions are available upon request with PPAP documentation and IATF 16949 manufacturing. The base SBR20A300CTFP shares die and process with AEC-Q101 variants - consult Diodes' Automotive Product Definitions page for change-controlled part numbers and qualification status.
