Product details
Overview
MBR20150PTH from Taiwan Semiconductor is a 20A, 150V AEC-Q101 qualified Schottky barrier rectifier in TO-247AD package, featuring 1.02V max forward voltage at 20A/25°C, 0.98V at 20A/125°C, and 5mA max reverse current at 150V/125°C. It delivers high surge capability (150A IFSM), low thermal resistance (1°C/W RθJC), and is used in automotive-grade DC-DC converters and industrial SMPS.
For engineers reviewing the MBR20150PTH datasheet, MBR20150PTH pinout, MBR20150PTH application, or MBR20150PTH equivalent, key selection factors include its AEC-Q101 qualification, 150V VRRM, dual-die TO-247AD construction, junction temperature range (–55°C to +150°C), and guard ring–enabled overvoltage protection.
Technical Context
This device is a single-package, dual-die Schottky rectifier optimized for high-efficiency switching applications. Its architecture integrates two independent Schottky junctions in one TO-247AD case with shared cathode connection, enabling synchronous rectification or parallel operation without external isolation.
It operates across –55°C to +150°C junction temperature, supports 8.3ms half-sine surge up to 150A, and maintains stable reverse leakage (<5mA at 150V/125°C) due to guard ring design and optimized epitaxial layer structure.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse voltage; defines safe blocking capability in DC-DC flyback or buck output stages |
| IF | 20 A - Continuous forward current rating; supports sustained 20A conduction without derating below 100°C case temperature |
| IFSM | 150 A - Non-repetitive surge current (8.3ms); enables robust start-up and fault tolerance in power supplies |
| VF @ 20A/25°C | 1.02 V max - Low conduction loss; reduces power dissipation by ~2W vs. silicon diodes at same current |
| RθJC | 1 °C/W - Junction-to-case thermal resistance; allows direct heatsink mounting with minimal thermal interface resistance |
| IR @ 150V/125°C | 5 mA max - Reverse leakage under worst-case thermal and voltage stress; ensures stability in high-temp automotive environments |

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 (non-isolated tab), 1.05V VF max @ 20A/25°C | Lacks AEC-Q101 qualification; not approved for automotive underhood use | Select for cost-sensitive industrial SMPS where automotive qualification is unnecessary |
| ON Semiconductor MBR20150CT | 20A/150V, TO-220AB package, single-die, 1.1V VF max @ 20A/25°C, RθJC = 2.5°C/W | Higher thermal resistance limits continuous current to ≤14A at 100°C case; unsuitable for high-power density designs | Select only when board space constraints prohibit TO-247AD footprint and thermal budget permits derating |
Compared with VS-20CPH15 and MBR20150CT, MBR20150PTH provides AEC-Q101 compliance, lower thermal resistance (1°C/W), and dual-die flexibility-making it the preferred choice for automotive and high-density industrial power where reliability and thermal performance are critical.

FAQ
What is the maximum junction temperature rating for MBR20150PTH?
The MBR20150PTH has a maximum junction temperature (TJMAX) of +150°C, verified per AEC-Q101 stress testing. This rating enables reliable operation in under-hood automotive applications and high-ambient industrial environments. The device must be mounted to a heatsink capable of maintaining case temperature ≤125°C at full 20A load to stay within this limit. Thermal design should account for RθJC = 1°C/W and interface resistance.
Is MBR20150PTH pin-compatible with MBR20150CT?
No, MBR20150PTH is not pin-compatible with MBR20150CT. MBR20150PTH uses a TO-247AD package with isolated cathode tab and three terminals (Anode 1, Anode 2, Cathode), while MBR20150CT uses TO-220AB with non-isolated tab and two terminals (Anode, Cathode). PCB layout, thermal mounting, and circuit topology differ fundamentally-direct substitution requires redesign.
Does MBR20150PTH have a guard ring structure?
Yes, MBR20150PTH incorporates a guard ring structure explicitly documented in its datasheet features and mechanical data section. This design mitigates edge breakdown under high dv/dt transients, increasing ruggedness in switching applications such as DC-DC converters and motor drives where fast voltage transitions occur.
What is the reverse leakage current of MBR20150PTH at 150V and 125°C?
At rated VR = 150V and junction temperature TJ = 125°C, the MBR20150PTH exhibits a maximum reverse current (IR) of 5 mA, as specified in the Electrical Specifications table. This value is measured under pulse conditions (PW = 30 ms) and reflects stable performance under worst-case thermal and voltage stress typical in automotive underhood environments.
How does the dual-die configuration of MBR20150PTH affect circuit implementation?
The dual-die configuration in MBR20150PTH provides two independent anodes sharing one cathode (tab). This enables flexible topologies: paralleling for 40A capacity, interleaving for reduced EMI, or separate channel rectification in multi-output supplies. Unlike single-die devices, it avoids cross-conduction risk when used with independent gate drivers, and eliminates need for external diode pairing.
