Product details
Overview
MBR20150PT from Taiwan Semiconductor is a 20A, 150V dual-die Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring 1.02V max forward voltage at 20A/25°C, 0.98V at 20A/125°C, and 5mA max reverse leakage at 150V/125°C. It delivers high surge current capability (150A IFSM), low thermal resistance (1°C/W RθJC), and AEC-Q101 qualification for automotive-grade reliability in DC–DC converters and SMPS.
For engineers reviewing the MBR20150PT datasheet, MBR20150PT pinout, MBR20150PT application, or MBR20150PT equivalent, key selection criteria include its 150V VRRM rating, dual-die configuration enabling parallel diode operation without external balancing, TO-247AD mechanical robustness, and verified performance under 125°C junction temperature with <1V forward drop.
Technical Context
This device integrates two independent Schottky die in a single TO-247AD package with common cathode connection, supporting high-current, low-loss rectification in continuous conduction mode topologies. Its guard ring structure provides overvoltage protection, while the 10,000 V/μs dV/dt rating ensures stability during fast-switching transients in high-frequency power supplies.
The MBR20150PT operates across –55°C to +150°C junction temperature range and maintains ≤5mA reverse leakage at rated 150V and 125°C - critical for thermal management in compact, sealed power modules where heat dissipation is constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - maximum repetitive reverse voltage; defines safe blocking capability in 120VAC-derived DC bus applications |
| IF | 20 A - average forward current per diode; supports sustained 20A output in dual-phase or interleaved converter designs |
| IFSM | 150 A - non-repetitive surge current (8.3ms half-sine); withstands inrush and fault currents without failure |
| VF @ 20A/25°C | 1.02 V max - low conduction loss enables >92% efficiency in 12V–48V output SMPS at full load |
| RθJC | 1 °C/W - enables direct heatsink mounting with minimal thermal interface resistance for high-power density layouts |
| IR @ 150V/125°C | 5 mA max - low leakage preserves regulation margin and reduces standby power in always-on systems |
| TJ max | +150 °C - allows operation in engine-bay or industrial enclosures without derating below full current |

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-20CPH15 | Same 20A/150V rating, TO-247AC package, but single-die construction and no AEC-Q101 qualification | Lacks dual-die current sharing; requires external balancing for parallel use; not approved for automotive underhood use | Select when cost sensitivity outweighs automotive qualification and dual-die benefits |
| ON Semiconductor MURB2015CT | Ultra-fast recovery diode (not Schottky), 20A/150V, TO-247AC, VF = 1.75V typical at 20A | Higher conduction loss increases thermal stress; suitable only where reverse recovery softness is prioritized over efficiency | Select only if EMI reduction from soft recovery is mandatory and efficiency loss is acceptable |
Compared with VS-20CPH15 and MURB2015CT, the MBR20150PT uniquely combines AEC-Q101 qualification, dual-die architecture, and sub-1V forward voltage - making it the only choice for thermally constrained, automotive-grade, high-efficiency rectification where reliability and power density are jointly critical.

FAQ
What is the maximum junction temperature rating for the MBR20150PT?
The MBR20150PT has a maximum junction temperature (TJ max) of +150°C, validated across its full operating current range. This rating allows uninterrupted 20A conduction in environments up to 85°C ambient when mounted on a heatsink with ≤1°C/W total thermal resistance. The device maintains specified electrical parameters-including 5mA reverse leakage and 1.02V forward voltage-up to this limit, making it suitable for under-hood automotive and enclosed industrial applications.
Does the MBR20150PT have AEC-Q101 qualification?
Yes, the MBR20150PT is AEC-Q101 qualified, as confirmed in the official Taiwan Semiconductor datasheet revision H2103. This qualification covers stress testing for temperature cycling, humidity bias, high-temperature operating life, and mechanical shock-ensuring suitability for automotive powertrain and body electronics. Note that AEC-Q101 status applies to the "MBR20150PTH" ordering code; standard "MBR20150PT" is not qualified unless explicitly ordered with the "H" suffix.
What is the forward voltage of the MBR20150PT at 20A and 125°C?
The MBR20150PT exhibits a maximum forward voltage (VF) of 0.98V at 20A and 125°C junction temperature, per the Electrical Specifications table in the Taiwan Semiconductor datasheet. This value reflects real-world thermal performance in high-ambient environments and enables accurate loss modeling for thermal design. At 25°C, VF is 1.02V max under identical conditions-demonstrating favorable temperature coefficient for Schottky devices.
How is the pinout configured for the dual-die structure of the MBR20150PT?
The MBR20150PT uses a three-terminal TO-247AD package with Lead 1 as Anode 1, Lead 2 as Anode 2, and Lead 3 as the common cathode. This configuration enables independent control of each diode's anode while sharing a single cathode output node-ideal for interleaved or dual-phase rectification without external current-sharing components. Polarity is marked on the device body per JEDEC standards.
What packaging and compliance certifications apply to the MBR20150PT?
The MBR20150PT is supplied in TO-247AD (TO-3P) package with matte tin-plated leads, UL 94V-0 flammability-rated molding compound, and RoHS/REACH compliance. It holds UL Recognition File #E-326243 and meets IEC 61249-2-21 halogen-free requirements. The device also passes JESD201 Class 2 whisker testing and supports soldering per J-STD-002, ensuring long-term interconnect reliability in automated assembly lines.
