Product details
Overview
MBR2090CT from Taiwan Semiconductor is a 20A dual-die Schottky barrier rectifier in TO-220AB package, rated for 90V repetitive peak reverse voltage (VRRM), 150A surge current (IFSM), and maximum junction temperature of 150°C; it delivers 0.85V typical forward voltage at 10A/25°C and 0.95V at 20A/25°C, enabling high-efficiency operation in DC-DC converters.
For engineers reviewing the MBR2090CT datasheet, MBR2090CT pinout, MBR2090CT application, or MBR2090CT equivalent, key selection criteria include verified VRRM=90V, dual-die configuration with common-cathode topology, thermal resistance RθJC=2°C/W, low IR=5mA @ 125°C, and AEC-Q101 qualification availability (MBR2090CTH variant).
Technical Context
The MBR2090CT integrates two independent Schottky diodes in a single TO-220AB package with common-cathode configuration, supporting synchronous rectification and dual-output power conversion topologies. Its guard ring structure provides overvoltage protection, and it sustains 10,000 V/μs critical rate of rise of off-state voltage (dv/dt).
Designed for high-frequency switching applications, the device exhibits low forward voltage drop and fast recovery characteristics-no reverse recovery time (trr) specified due to Schottky construction-and maintains stable performance across -55°C to +150°C junction temperature range with 2°C/W junction-to-case thermal resistance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-20CPH09-M3 | Same TO-220AB package, 20A/90V rating, but single-die vs. dual-die; VF = 0.87V @ 20A/25°C | Lacks common-cathode dual-anode topology; requires two separate devices for dual-output use | Select when only single-output rectification is needed and board space permits discrete placement |
| ON Semiconductor MBR2090CTG | Identical electrical specs and dual-die TO-220AB mechanical form; Pb-free, halogen-free, and AEC-Q101 qualified (MBR2090CTGH) | Direct functional match with identical pinout and thermal profile; differs only in manufacturer branding and traceability | Preferred for second-source assurance where Taiwan Semiconductor supply continuity is constrained |
Compared with VS-20CPH09-M3 and MBR2090CTG, the MBR2090CT uniquely integrates two 90V/20A Schottky diodes in one TO-220AB package with common cathode, reducing component count and layout complexity for dual-rail power supplies without sacrificing thermal or surge performance.

FAQ
What is the pin configuration of the MBR2090CT?
The MBR2090CT uses a 3-pin TO-220AB package with Pin 1 (tab) as Anode 1, Pin 2 as the common Cathode, and Pin 3 as Anode 2. This common-cathode dual-anode arrangement enables independent input routing while sharing a single return path-critical for dual-output DC-DC designs. The metal tab is electrically connected to Anode 1 and serves as the primary thermal interface.
Does the MBR2090CT have AEC-Q101 qualification?
The standard MBR2090CT is not AEC-Q101 qualified, but the MBR2090CTH variant is explicitly qualified per AEC-Q101 Rev D for automotive applications. This qualification covers stress testing including HTGB, HTRB, and temperature cycling, confirming suitability for under-hood environments. Always verify the "H" suffix in the ordering code when automotive compliance is required.
What is the maximum junction temperature and thermal resistance of the MBR2090CT?
The MBR2090CT has a maximum junction temperature (TJ max) of 150°C and a junction-to-case thermal resistance (RθJC) of 2°C/W. This value applies to the entire family spanning MBR2090CT through MBR20200CT. Effective heatsinking is essential to maintain TJ ≤ 150°C under full 20A load, especially at elevated ambient temperatures.
How does the forward voltage of the MBR2090CT vary with temperature and current?
The MBR2090CT exhibits VF = 0.85V typical at 10A/25°C and 0.95V at 20A/25°C; at 125°C, VF drops to 0.75V @ 10A and 0.85V @ 20A. This negative temperature coefficient improves thermal stability in parallel operation and reduces conduction loss at elevated temperatures-unlike silicon PN diodes, which increase VF with temperature.
Is the MBR2090CT suitable for high-frequency switching applications like LLC resonant converters?
Yes-the MBR2090CT is well-suited for high-frequency switching applications including LLC resonant converters due to its Schottky construction, which eliminates reverse recovery charge (Qrr) and associated switching losses. With no trr specification and low junction capacitance, it supports efficient operation up to several hundred kHz, provided thermal design accommodates 2°C/W RθJC and 150A IFSM surge demands.
