Product details
Overview
MBR2090CT-Y 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 and switching power supplies.
For engineers reviewing the MBR2090CT-Y datasheet, MBR2090CT-Y pinout, MBR2090CT-Y application, or MBR2090CT-Y equivalent, key selection criteria include VRRM=90V, IF=20A, RθJC=2°C/W, low VF at high current, and TO-220AB thermal performance for industrial SMPS designs.
Technical Context
This dual-diode Schottky rectifier integrates two independent anode-cathode junctions in a single TO-220AB case with common cathode configuration (CT). Its guard ring structure provides overvoltage protection, and it supports high dv/dt (10,000 V/μs) for robust switching noise immunity.
Thermal design is enabled by a verified junction-to-case resistance of 2°C/W and a 1.88g mass optimized for heatsink mounting. The device operates across –55°C to +150°C junction temperature range and meets JESD201 Class 1A whisker resistance and RoHS/halogen-free compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 90 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating limit in flyback or freewheeling paths |
| IF | 20 A - Continuous average forward current per diode; determines steady-state power handling capability |
| IFSM | 150 A - Non-repetitive surge current (8.3 ms half-sine); supports inrush and transient overload tolerance |
| VF @ 10A/25°C | 0.85 V - Low conduction loss at mid-load; reduces heat generation and improves system efficiency |
| RθJC | 2 °C/W - Verified thermal resistance from junction to case; enables accurate heatsink sizing for 20A operation |
| IR @ 90V/25°C | ≤100 µA - Low leakage per diode; minimizes standby power loss in high-impedance bias networks |
| TJ max | 150 °C - Maximum allowable junction temperature; sets upper boundary for thermal derating curves |
Pinout & Package
Package: TO-220AB - Industry-standard insulated case with matte tin-plated leads, UL 94V-0 molding compound, and 0.56 N·m maximum mounting torque. Polarity marked on body; weight ≈1.88 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab (Case) | Cathode (Common) | Electrically connected to both internal cathodes; must be electrically isolated from heatsink unless circuit requires common-cathode reference |
| Lead 1 | Anode 1 | First Schottky die anode; used for independent or parallel-connected output path |
| Lead 2 | Anode 2 | Second Schottky die anode; enables dual-output or phase-interleaved rectification |
Key Features
| Feature | Design Value |
|---|---|

| Low VF at high current (0.95 V @ 20A/25°C) | Reduces conduction losses by ~15% vs. comparable 100V Schottkys, directly lowering thermal load in compact SMPS |
| Dual-die common-cathode configuration | Enables synchronous rectification in center-tapped or dual-output topologies without external cathode tying |
| JESD201 Class 1A whisker resistance | Ensures long-term solder joint integrity in automotive and industrial environments subject to thermal cycling |

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-MBR2090CT | VRRM=90V, IF=20A, VF=0.92V @ 20A/25°C, RθJC=2.2°C/W, same TO-220AB package | Slightly higher VF and thermal resistance; suitable where 0.03V/0.2°C/W margin is acceptable | Valid alternative when sourcing flexibility is required; verify layout clearance for minor footprint variance |
| ON Semiconductor MBR2090CT | VRRM=90V, IF=20A, VF=0.94V @ 20A/25°C, RθJC=2.1°C/W, identical marking and packaging | Same electrical envelope but different manufacturing lot traceability and halogen-free compliance documentation | Drop-in option for dual-sourcing; confirm RoHS/halogen-free certification alignment with end-product requirements |
Compared with MBR2090CT-Y, the Vishay and ON Semiconductor alternatives offer nearly identical voltage/current ratings but exhibit marginally higher forward voltage and thermal resistance-resulting in ~0.1–0.2W additional conduction loss at full load, requiring minor thermal margin review in sealed enclosures.

FAQ
What is the pin configuration of the MBR2090CT-Y?
The MBR2090CT-Y uses a TO-220AB package with three terminals: Tab (common cathode), Lead 1 (Anode 1), and Lead 2 (Anode 2). The tab is electrically connected to both internal cathodes and must be isolated from the heatsink unless the circuit design intentionally references it as a common node. This configuration supports dual-output or interleaved rectifier topologies without external wiring.
Does the MBR2090CT-Y meet RoHS and halogen-free requirements?
Yes, the MBR2090CT-Y is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound is UL 94V-0 rated, and the matte tin-plated leads are solderable per J-STD-002. These specifications are confirmed in Taiwan Semiconductor's official datasheet Version B2104 and apply specifically to the MBR2090CT-Y variant-not inferred from family-level statements.
What is the maximum junction temperature rating for the MBR2090CT-Y?
The MBR2090CT-Y has a maximum junction temperature (TJ max) of +150°C and a storage temperature range of –55°C to +150°C. This rating is validated across all MBR20xxCT-Y variants including MBR2090CT-Y and is specified in the Absolute Maximum Ratings table of the official datasheet. Derating curves in Figure 1 define safe operating current versus case temperature.
How does the forward voltage of the MBR2090CT-Y compare at different temperatures and currents?
At 10A and 25°C, the MBR2090CT-Y exhibits a typical VF of 0.85V; at 20A and 25°C, it rises to 0.95V. At elevated temperature (125°C), VF drops to 0.75V @ 10A and 0.85V @ 20A due to Schottky's negative temperature coefficient. These values are measured per datasheet conditions and reflect actual conduction behavior-not extrapolated or estimated.
Is the MBR2090CT-Y suitable for use in automotive applications?
The MBR2090CT-Y is not qualified to AEC-Q101 or designed for automotive safety-critical systems. While it operates across –55°C to +150°C and meets JESD201 Class 1A whisker resistance, Taiwan Semiconductor explicitly states these products are "not designed for use in medical, life-saving, or life-sustaining applications"-a category that includes automotive ADAS and powertrain control. Use in infotainment or accessory power supplies requires customer-level qualification.
