Product details
Overview
MBRS1590CT from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 15 A average forward current, 90 V repetitive peak reverse voltage (VRRM), and 150 A non-repetitive surge current (IFSM). It operates up to 150 °C junction temperature and delivers 0.92 V typical forward voltage at 7.5 A and 25 °C - optimized for high-efficiency DC/DC converters.
For engineers reviewing the MBRS1590CT datasheet, MBRS1590CT pinout, MBRS1590CT application, or MBRS1590CT equivalent, key selection criteria include its dual-die configuration, 90 V VRRM, low thermal resistance (RθJC = 2 °C/W), RoHS/halogen-free compliance, and J-STD-020 Level 1 moisture sensitivity rating.
Technical Context
The MBRS1590CT integrates two independent Schottky diodes in a single TO-263AB surface-mount package with common cathode configuration. Its guard ring structure provides overvoltage protection, and it supports automated placement per industry standards.
Thermally, it achieves RθJC = 2 °C/W and RθJA = 50 °C/W, enabling high-power-density designs. At 125 °C junction temperature, forward voltage remains 0.82 V (typ) at 7.5 A, while reverse leakage is limited to 5 mA per diode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 90 V - maximum blocking voltage per diode; defines usable input range in 48 V or 60 V SMPS rails |
| IF | 15 A - continuous average forward current per diode; supports high-current output stages |
| IFSM | 150 A - 8.3 ms half-sine surge rating; handles inrush and transient overload without failure |
| VF @ 7.5 A, 25 °C | 0.92 V (typ) - low conduction loss enables >92% efficiency in 12 V–24 V output converters |
| RθJC | 2 °C/W - enables direct heatsinking to PCB copper or external metal; critical for thermal management |
| TJ max | +150 °C - allows operation in high-ambient industrial or enclosed power supply environments |
| IR @ 90 V, 125 °C | 5 mA (max) - low leakage preserves efficiency at elevated temperatures |

| Pin 2 (Cathode) | Common Cathode | Shared output node for both diodes; soldered to large copper pour for thermal and current handling |
| Pin 3 (Anode B) | Anode of Diode B | Enables dual-output or interleaved converter topologies; electrically isolated from Anode A |
Key Features
| Feature | Design Value |

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-MBR1590CT | Identical VRRM (90 V), IF (15 A), TO-263AB package; VF = 0.90 V (typ) at 7.5 A, 25 °C - marginally lower conduction loss | Same dual-common-cathode function; slightly tighter VF tolerance supports higher efficiency targets | Select when <0.02 V VF reduction justifies sourcing from alternate vendor |
| ON Semiconductor MBR1590CT | VRRM = 90 V, IF = 15 A, TO-263AB; VF = 0.95 V (max) at 7.5 A, 25 °C - wider VF spec limit than MBRS1590CT's 0.92 V typ | Compatible in layout and function; higher VF max may require thermal margin review in high-ambient designs | Select when second-source qualification requires ON Semi's QCI or automotive-qualified variants |
Compared with VS-MBR1590CT and MBR1590CT, the MBRS1590CT offers a balanced combination of verified 0.92 V typical forward voltage, 2 °C/W thermal resistance, and Level 1 moisture sensitivity - making it especially suitable for high-volume, thermally constrained industrial power supplies where process consistency and reflow simplicity are prioritized.

FAQ
What is the pin configuration of the MBRS1590CT?
The MBRS1590CT uses a 3-pin TO-263AB (D2PAK) package with a common-cathode dual-diode configuration: Pin 1 is Anode A, Pin 2 is the shared Cathode, and Pin 3 is Anode B. Polarity is marked on the device body, and the cathode tab is electrically connected to Pin 2 for direct PCB thermal coupling.
Does the MBRS1590CT support reflow soldering without baking?
Yes - the MBRS1590CT has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it can be stored indefinitely at ≤30 °C/60% RH and placed directly into standard lead-free reflow profiles without preconditioning or baking, simplifying manufacturing flow.
What is the maximum junction temperature and how does it affect design?
The MBRS1590CT has a maximum junction temperature (TJ) of +150 °C. This allows operation in high-ambient environments such as enclosed power supplies or industrial enclosures. Designers must ensure that power dissipation - calculated from IF² × RF and VF × IF - stays within thermal limits using the specified RθJC = 2 °C/W and RθJA = 50 °C/W values.
How does the guard ring feature improve reliability in the MBRS1590CT?
The guard ring in the MBRS1590CT mitigates edge breakdown under high dv/dt or transient overvoltage conditions - particularly during MOSFET switching transitions in SMPS. This extends operational lifetime in noisy or poorly filtered input stages and improves robustness against line surges without requiring additional clamping components.
Is the MBRS1590CT halogen-free and RoHS compliant?
Yes - the MBRS1590CT is fully RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound and plating meet environmental regulations for sale in EU, China, and other regulated markets, with no exemptions required for brominated flame retardants or chlorine-based compounds.
