Product details
Overview
MBRB20200CT-13 from Diodes Incorporated is a 20A dual common-cathode Schottky barrier rectifier in TO263AB (D2PAK) package, rated for 200V peak reverse voltage, 0.89V max forward voltage at 10A/25°C, and 0.1mA max leakage current at 200V/25°C. It serves as polarity protection and freewheeling diode in DC power supplies and motor drive circuits.
For engineers reviewing the MBRB20200CT-13 datasheet, MBRB20200CT-13 pinout, MBRB20200CT-13 application, or MBRB20200CT-13 equivalent, key selection criteria include its dual-leg thermal resistance (RθJC = 5°C/W), AEC-Q101 qualification, RoHS-compliant matte tin finish, and 170A non-repetitive surge rating for transient robustness.
Technical Context
This device integrates two independent Schottky diodes sharing a common cathode terminal, enabling synchronous rectification or dual-path DC output management. Its guard ring die construction enhances transient immunity, while low VF minimizes conduction losses in high-current switching converters.
Thermal performance is optimized via direct copper leadframe mounting and low RθJC (5°C/W), allowing sustained 10A per leg operation with proper heatsinking. The TO263AB package supports surface-mount reflow and offers superior thermal dissipation versus TO220 alternatives.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual common-cathode Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-20CPH02-M3 | Same 200V VRRM, 10A IO, but VF = 0.92V max; TO263AB package; no AEC-Q101 qualification | Lacks automotive qualification; suitable for commercial/industrial only | Select when AEC-Q101 is not required and marginally higher VF is acceptable |
| ON Semiconductor MBR20200CT | Identical ratings and TO263AB package; VF = 0.89V max; AEC-Q101 qualified; RoHS compliant | Drop-in functional replacement with identical thermal and electrical behavior | Preferred for second-source assurance where Diodes Inc. supply continuity is critical |
Compared with VS-20CPH02-M3, MBRB20200CT-13 delivers automotive-grade reliability and lower conduction loss; versus MBR20200CT, it shares identical specs but differs in traceability and manufacturing lot control-critical for OEM BOM lock-in.

FAQ
What is the maximum junction temperature for continuous operation?
The MBRB20200CT-13 has an operating junction temperature range of –55°C to +175°C. For reliable continuous operation at rated 10A per leg, thermal design must maintain TJ ≤ 150°C under worst-case ambient and power dissipation conditions, verified using RθJC = 5°C/W and RθJA = 20°C/W values.
Is the TO263AB package lead-free and RoHS compliant?
Yes. The MBRB20200CT-13 features a matte tin annealed finish over copper leadframe, fully compliant with EU RoHS Directive 2011/65/EU and Diodes Incorporated's halogen- and antimony-free "Green" standard (<900ppm Br+Cl, <1000ppm Sb).
How does the guard ring die construction improve reliability?
The guard ring structure suppresses electric field concentration at the silicon periphery, preventing premature avalanche breakdown during voltage transients. This extends device lifetime in applications subject to load dump, inductive switching, or ESD events-validated per AEC-Q101 stress tests.
Can this part replace a single-diode TO220 rectifier in existing layouts?
No. The MBRB20200CT-13 is a dual common-cathode device in TO263AB, requiring three pads (two anodes + one cathode) and different thermal land patterns. Direct substitution would necessitate PCB redesign to accommodate the D2PAK footprint and thermal pad layout per AP02001 guidelines.
