Product details
Overview
MBR1590CT from Taiwan Semiconductor is a 15A 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 low forward voltage drop (0.92V typ. at 7.5A, 25°C) and ultra-low reverse leakage (100µA max at 25°C), enabling high-efficiency operation in DC-DC converters and industrial power supplies.
For engineers reviewing the MBR1590CT datasheet, MBR1590CT pinout, MBR1590CT application, or MBR1590CT equivalent, key selection criteria include its 90V VRRM rating, dual-diode configuration with common-cathode topology, thermal resistance (RθJC = 1.5°C/W), AEC-Q101 qualification availability, and compatibility with high-frequency switching topologies requiring fast recovery and minimal conduction loss.
Technical Context
The MBR1590CT integrates two independent Schottky diodes in a single TO-220AB package with common-cathode connection, supporting dual-output or full-wave rectification. Its guard ring structure provides overvoltage protection, while the 10,000 V/μs critical dv/dt rating ensures robustness against rapid voltage transients in high-speed switching environments.
Designed for operation up to 150°C junction temperature, it features RθJA = 10°C/W (free-air) and RθJC = 1.5°C/W (case-to-junction), enabling effective heat transfer to heatsinks. Reverse leakage remains tightly controlled at ≤100 µA at 25°C and ≤5 mA at 125°C under rated 90V reverse bias.
Key Specifications

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-15MQ090NTRP | Same 90V VRRM, 15A IF, TO-220AC package; slightly higher VF (0.95V typ.) and lower IFSM (120A). | Not AEC-Q101 qualified; limited to commercial/industrial use only. | Select when cost sensitivity outweighs automotive qualification or surge margin needs. |
| ON Semiconductor MBR1590CTG | Identical electrical specs and TO-220AB package; Pb-free, RoHS-compliant variant with same marking and pinout. | No functional difference; fully interchangeable in existing designs. | Choose for legacy ON Semi BOM alignment or distributor stock preference. |
Compared with MBR1590CT, VS-15MQ090NTRP trades surge robustness for lower cost, while MBR1590CTG offers identical performance with alternate branding-neither is pin-compatible by default unless verified in layout, but both serve the same 90V/15A dual-Schottky rectifier function.

FAQ
What is the maximum junction temperature rating for the MBR1590CT?
The MBR1590CT has a maximum junction temperature (TJ max) of 150°C, allowing reliable operation in high-ambient environments such as enclosed power supplies or under-hood automotive locations. This rating is maintained across its full current and voltage operating range, provided thermal design respects RθJC = 1.5°C/W and adequate heatsinking is applied. The MBR1590CT must not exceed this limit to avoid parametric drift or premature failure.
Does the MBR1590CT have AEC-Q101 qualification?
The base MBR1590CT is not AEC-Q101 qualified, but the MBR1590CTH variant-identical in all electrical and mechanical specifications-is explicitly qualified per AEC-Q101 for automotive applications. Users requiring automotive-grade validation must specify the "H" suffix part number; the standard MBR1590CT is intended for industrial and commercial use only.
What is the forward voltage drop of the MBR1590CT at full rated current?
The MBR1590CT does not specify VF at 15A and 25°C in its official datasheet; however, VF is characterized at 7.5A (0.92V typ.) and 15A at elevated temperature (0.82V typ. at 125°C). At 15A and 25°C, VF is estimated between 0.95–1.05V based on curve extrapolation from Fig.4, but design margins should rely on the 0.92V typ. @ 7.5A value for conservative thermal modeling.
How is the pinout configured for the dual-diode structure in the MBR1590CT?
The MBR1590CT uses a common-cathode TO-220AB configuration: Pin 1 is Anode 1, Pin 2 is the shared Cathode, and Pin 3 is Anode 2. This arrangement supports full-wave rectification with center-tapped transformers or dual-output DC-DC stages. Polarity is marked on the device body, and the cathode tab is electrically connected to Pin 2-critical for proper heatsink isolation if floating operation is required.
What packaging and ordering options are available for the MBR1590CT?
The MBR1590CT is supplied in TO-220AB package, packed 50 units per tube. Ordering codes include MBR1590CT (standard) and MBR1590CTH (AEC-Q101 qualified). No tape-and-reel or tray options are specified in the datasheet. Lead finish is matte tin, compliant with J-STD-002 solderability standards, and the device carries green compound marking per RoHS and halogen-free requirements.
