Product details
Overview
MBRS2590CTH from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 25 A average forward current, 90 V repetitive peak reverse voltage (VRRM), and 200 A non-repetitive surge current (IFSM). It delivers low forward voltage drop (0.85 V max at 12.5 A, 25°C) and supports automotive-grade reliability with AEC-Q101 qualification.
For engineers reviewing the MBRS2590CTH datasheet, MBRS2590CTH pinout, MBRS2590CTH application, or MBRS2590CTH equivalent, key selection factors include its 90 V VRRM, dual-common-cathode configuration, 1.0 °C/W junction-to-case thermal resistance, and suitability for high-frequency DC/DC converters and reverse battery protection circuits where low conduction loss and fast switching are critical.
Technical Context
The MBRS2590CTH integrates two independent Schottky diodes in a single TO-263AB surface-mount package with common cathode connection. Its design targets high-efficiency power conversion in constrained thermal environments, leveraging low forward voltage and high surge capability to minimize conduction losses and withstand transient overcurrents.
It operates across –55°C to +150°C junction temperature range, features guard ring structure for overvoltage robustness, and meets J-STD-020 moisture sensitivity level 1. Reverse leakage is limited to 100 µA at 25°C and 7.5 mA at 125°C under rated 90 V reverse bias.
Key Specifications

FAQ
What is the maximum junction temperature rating for MBRS2590CTH?
The MBRS2590CTH has a maximum junction temperature (TJ) of +150°C and a minimum of –55°C. This wide operating range supports deployment in under-hood automotive environments and high-ambient industrial enclosures. Thermal design must ensure that actual junction temperature stays within this limit under worst-case power dissipation and ambient conditions. The device's 1.0 °C/W RθJC enables precise thermal modeling when mounted on properly sized copper pads or heatsinks.
Is MBRS2590CTH pin-compatible with other parts in the MBRS25xxCTH family?
Yes, all MBRS25xxCTH variants-including MBRS2535CTH, MBRS2560CTH, and MBRS25150CTH-share identical TO-263AB (D2PAK) package dimensions, pinout, and thermal pad layout. This allows board-level voltage scalability without layout revision. However, forward voltage, reverse leakage, and surge capability vary across the family, so electrical validation is required when substituting within the same footprint.
Does MBRS2590CTH require special handling during PCB assembly?
No special handling is required: MBRS2590CTH is rated MSL Level 1 per J-STD-020, meaning it can be stored indefinitely at ambient conditions and placed directly into standard lead-free reflow profiles without baking. Its matte tin-plated leads comply with J-STD-002 for solderability, and the UL 94V-0 molding compound ensures flame resistance during soldering and operation.
What is the reverse leakage current specification for MBRS2590CTH at elevated temperature?
At 90 V reverse bias and 125°C junction temperature, MBRS2590CTH exhibits a maximum reverse leakage current (IR) of 7.5 mA per diode. This value is confirmed in the manufacturer's electrical specifications table and reflects real-world behavior in high-temperature automotive applications such as engine control modules. Leakage remains stable over time due to the guard ring structure and optimized Schottky metallization.
Can MBRS2590CTH be used in a dual-anode, common-cathode configuration for OR-ing applications?
Yes, MBRS2590CTH is explicitly designed for dual-anode, common-cathode operation. Pins 1 and 3 serve as independent anodes, while Pin 2 (and the exposed thermal pad) forms the shared cathode node. This configuration enables straightforward implementation in redundant power supply OR-ing, reverse polarity protection, and dual-input power management-without external cathode tying or additional components.
