Product details
Overview
MBRS15150CT from Taiwan Semiconductor is a 15 A, 150 V dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, optimized for high-efficiency switching mode power supplies with low forward voltage (0.95 V at 7.5 A, 25°C) and high surge capability (150 A IFSM). It serves as the output rectification stage in DC-DC converters and AC-DC adapters.
For engineers reviewing the MBRS15150CT datasheet, MBRS15150CT pinout, MBRS15150CT application, or MBRS15150CT equivalent, key selection criteria include peak reverse voltage rating (150 V), thermal resistance (RθJC = 2 °C/W), junction temperature limit (+150°C), and moisture sensitivity level (J-STD-020 Level 1).
Technical Context
The MBRS15150CT integrates two independent Schottky diodes in a common-cathode configuration within a single TO-263AB thermally enhanced surface-mount package. Its guard ring structure provides overvoltage protection, and its low RθJC enables direct heatsinking to PCB copper.
Designed for high-frequency operation, it supports dv/dt up to 10,000 V/μs and exhibits low reverse recovery charge (Qrr not specified but inherent to Schottky architecture), minimizing switching losses in SMPS topologies operating above 100 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse voltage; defines safe blocking capability in high-voltage DC-DC outputs. |
| IF | 15 A - Continuous forward current per diode; determines steady-state power handling without derating at TA = 25°C. |
| IFSM | 150 A - Non-repetitive surge current (8.3 ms half-sine); supports inrush and transient overload tolerance. |
| VF @ 7.5A, 25°C | 0.95 V - Forward voltage drop; directly impacts conduction loss and thermal rise in high-current paths. |
| RθJC | 2 °C/W - Junction-to-case thermal resistance; enables efficient heat transfer to external heatsink or thermal pad. |
| TJ max | +150°C - Maximum junction temperature; sets upper thermal operating limit for reliability under sustained load. |
| IR @ 150V, 125°C | 5 mA - Reverse leakage per diode; critical for standby power loss and thermal runaway avoidance in parallel configurations. |

FAQ
What is the maximum junction temperature rating for MBRS15150CT?
The MBRS15150CT has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet. This allows continuous operation in high-ambient environments such as enclosed server power supplies or industrial motor drives, provided thermal design maintains junction temperature below this limit. Derating curves confirm usable current down to 10 A at 100°C case temperature.
Does MBRS15150CT support automated SMT placement?
Yes, MBRS15150CT is qualified for automated surface-mount placement per its TO-263AB (D2PAK) package and J-STD-020 Level 1 moisture sensitivity classification. The matte tin-plated leads meet J-STD-002 solderability requirements, and the device's 1.37 g weight and symmetrical lead geometry ensure reliable pick-and-place yield. Reflow profiles must respect peak temperature limits defined in TSC's packaging specification L2103.
What is the reverse leakage current of MBRS15150CT at 150 V and 125°C?
Per the Taiwan Semiconductor datasheet, the MBRS15150CT exhibits a maximum reverse leakage current (IR) of 5 mA per diode at rated VRRM = 150 V and junction temperature of 125°C. This value is measured under pulse conditions (PW = 30 ms) and is critical for evaluating standby power loss in always-on auxiliary rails. At 25°C, leakage is ≤100 µA.
Is MBRS15150CT halogen-free and RoHS compliant?
Yes, MBRS15150CT is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the "Features" section of the official Taiwan Semiconductor datasheet. The molding compound meets UL 94V-0 flammability rating, and terminals pass JESD 201 Class 2 whisker testing-ensuring suitability for environmentally regulated industrial and consumer applications.
How does the guard ring feature benefit MBRS15150CT in real-world use?
The guard ring in MBRS15150CT enhances edge termination robustness, preventing premature avalanche breakdown under voltage transients. In practice, this allows the device to survive 150 V reverse spikes in flyback converters without external clamping, reducing bill-of-materials count and improving reliability in unregulated input conditions. It is especially valuable in automotive-grade auxiliary supplies where load dump events occur.
