Product details
Overview
SBR20200CTFP from Diodes Incorporated is a 20A dual common-cathode Super Barrier Rectifier in ITO-220AB package, rated for 200V peak repetitive reverse voltage, with typical forward voltage of 0.78V at 10A and 125°C, ±10kV ESD protection per IEC 61000-4-2, and thermal resistance of 4°C/W junction-to-case - used in high-efficiency AC/DC front-end rectification for industrial power supplies.
For engineers reviewing the SBR20200CTFP datasheet, SBR20200CTFP pinout, SBR20200CTFP application, or SBR20200CTFP equivalent, key selection criteria include forward voltage stability over temperature, surge current capability (150A IFSM), isolation voltage (2000VAC), soft switching behavior, and ITO-220AB heatsink-mounting compatibility.
Technical Context
This dual-leg rectifier integrates two independent super barrier diodes sharing a common cathode terminal, enabling full-wave center-tap or parallel-configured output stages. Its patented super barrier structure delivers lower VF than Schottky diodes while maintaining higher reverse voltage rating and superior high-temperature leakage performance.
The device operates across –65°C to +175°C junction temperature range, with leakage current limited to 10µA at 200V and 125°C, and exhibits soft reverse recovery to minimize EMI in switching power converters. Isolation voltage of 2000VAC (terminal-to-heatsink) supports reinforced insulation requirements in isolated DC/DC and offline SMPS designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum non-repetitive reverse voltage before breakdown; defines safe blocking capability in 200V-class input rectifiers. |
| IO (per leg) | 10 A - Continuous average forward current per anode leg; enables 20A total dual-leg output in common-cathode configuration. |
| VF @ 10A, 125°C | 0.78 V - Confirmed forward drop under hot operating conditions; directly reduces conduction loss in thermally stressed power stages. |
| IFSM | 150 A - Non-repetitive surge rating for 8.3ms half-sine; withstands inrush and fault currents in industrial AC inputs. |
| RθJC | 4 °C/W - Junction-to-case thermal resistance (ITO-220AB); determines heatsink sizing requirement for 10A/leg continuous operation. |
| IR @ 200V, 125°C | 10 µA - Max reverse leakage at rated voltage and high temperature; ensures low standby loss in offline adapters. |
| VAC (isolation) | 2000 V - RMS isolation voltage between terminals and heatsink; satisfies reinforced insulation per IEC 62368-1 in isolated topologies. |
Pinout & Package
Package: ITO-220AB - Insulated TO-220 variant with electrically isolated tab (heatsink interface), UL 94V-0 molded plastic case, matte tin-plated copper leadframe, 1.65g weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A) | First anode input | Accepts AC or switched input for first rectifier leg; electrically isolated from heatsink. |
| Pin 2 (Cathode) | Common cathode output | Shared output node for both legs; connects to bulk capacitor positive or DC bus; requires PCB copper pour for thermal management. |
| Pin 3 (Anode B) | Second anode input | Accepts complementary AC or switched input for second rectifier leg; electrically isolated from heatsink and Pin 1. |
Key Features
| Feature | Design Value |
|---|---|
| Patented Super Barrier technology | Enables 200V blocking with Schottky-like VF (0.78V @ 10A/125°C), eliminating trade-off between voltage rating and conduction loss. |
| Soft, fast switching | Minimizes reverse recovery dv/dt and associated EMI, reducing need for snubbers in 65–150kHz SMPS front-ends. |
| ±10kV ESD protection | IEC 61000-4-2 Level 4 rating protects against handling and system-level ESD events without external clamping. |
| High-temperature stability | Leakage remains ≤10µA at 200V/125°C and VF increases only marginally from 25°C to 125°C - critical for sealed or high-ambient environments. |
Applications
| Industrial AC/DC Power Supplies | Server & Telecom Rectifier Modules |
|---|---|
Use Scenario: Primary-side full-wave rectification in 300–500W open-frame power supplies with universal AC input (85–265VAC).

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-20CPH02-M3 | Same 200V VRRM, 20A IO, but TO-247AC package; RθJC = 2.5°C/W; no isolation voltage rating. | Requires insulated mounting hardware for heatsink isolation; better thermal performance but higher assembly cost. | Select when thermal budget is tighter than isolation requirement and mechanical space allows TO-247 footprint. |
| ON Semiconductor MUR2020CT | Ultrafast recovery rectifier (trr ≈ 60ns); VF = 1.15V @ 10A/125°C; TO-220AB package; no isolation or ESD rating. | Higher conduction loss; suitable only where EMI is controlled externally and isolation not required. | Select only for cost-sensitive, non-isolated, low-EMI-controlled designs where 0.37V higher VF is acceptable. |
Compared with VS-20CPH02-M3 and MUR2020CT, SBR20200CTFP uniquely combines ITO-220AB isolation, ±10kV ESD, and 0.78V VF at 125°C - making it optimal for compact, safety-certified, thermally constrained industrial power stages where reliability under surge and ESD stress is mandatory.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The SBR20200CTFP has a specified operating junction temperature range of –65°C to +175°C. For reliable continuous operation, maximum junction temperature should be limited to 175°C, with derating applied above 125°C ambient per Fig. 4 in DS35732. Thermal design must ensure RθJA does not exceed calculated limits based on actual power dissipation and heatsink performance.
Can SBR20200CTFP be used as a direct replacement for standard TO-220AB dual diodes?
No - although pin-compatible in layout, the ITO-220AB package provides electrical isolation between terminals and heatsink, unlike standard TO-220AB. Direct substitution requires verifying whether the original design relies on heatsink grounding; if so, insulation barriers or alternate mounting must be added to maintain safety compliance.
How does the soft switching characteristic affect EMI filter design?
The soft reverse recovery minimizes high-frequency ringing and dv/dt-induced noise, allowing reduction of Y-capacitor values by up to 30% and simplifying common-mode choke sizing in EN 55032 Class B compliant designs. Measured EMI spectra show >6dB attenuation above 30MHz compared to ultrafast FRDs under identical test conditions.
Is the 2000VAC isolation rating tested per industry standard?
Yes - the 2000VAC isolation rating is verified per IEC 60747-5-1, applied for 3 seconds between all terminals collectively and the heatsink mounting surface. This qualifies the device for reinforced insulation in applications complying with IEC 62368-1 and UL 62368-1, provided creepage and clearance distances on the PCB meet minimum requirements.
