Product details
Overview
MBRF30150CT from Taiwan Semiconductor is a 30A dual-die Schottky barrier rectifier in ITO-220AB package, rated for 150V repetitive peak reverse voltage (VRRM), 200A surge current (IFSM), and maximum junction temperature of 150°C. It delivers 0.95V forward voltage at 30A/25°C and 0.92V at 30A/125°C, enabling high-efficiency operation in DC-DC converters and industrial SMPS.
For engineers reviewing the MBRF30150CT datasheet, MBRF30150CT pinout, MBRF30150CT application, or MBRF30150CT equivalent, key selection criteria include VRRM=150V, IF=30A continuous, IFSM=200A, VF ≤1.05V @30A/25°C, and thermal resistance RθJC=4°C/W - all critical for thermal management and conduction loss in high-current switching power supplies.
Technical Context
This dual-die common-cathode Schottky rectifier integrates two independent 30A diodes sharing one cathode terminal, optimized for low forward voltage drop and fast recovery with no minority-carrier storage delay. Its guard ring structure provides overvoltage protection, and it meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements.
The device operates across -55°C to +150°C junction temperature range, supports 10,000 V/µs critical dv/dt rating, and exhibits 10 mA max reverse leakage per diode at 150°C and rated VR - essential for stable performance in thermally demanding automotive-qualified (AEC-Q101 optional) and industrial power systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating limit in flyback/freewheeling paths |
| IF | 30 A - Continuous average forward current per diode; determines heatsink sizing and steady-state power handling |
| IFSM | 200 A - Non-repetitive surge current (8.3 ms half-sine); enables robust startup and fault tolerance |

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-30CPH15 | Same ITO-220AB package, 30A/150V, but VF = 0.87V @30A/25°C (lower), RθJC = 3.5°C/W (better), no AEC-Q101 option | Preferred where lower conduction loss and thermal resistance are prioritized over automotive qualification | Select VS-30CPH15 for higher efficiency in telecom or server PSUs; verify cathode/anode pinout alignment before PCB reuse |
| ON Semiconductor MBR30H150CT | Identical ratings (30A/150V), same ITO-220AB, VF = 0.94V @30A/25°C, AEC-Q101 qualified as standard, RθJC = 4.2°C/W | Suitable for automotive-grade auxiliary supplies where qualification is mandatory and 0.1°C/W higher thermal resistance is acceptable | Choose MBR30H150CT when AEC-Q101 compliance is required without ordering H-suffix variant separately |
Compared with MBRF30150CT, VS-30CPH15 offers better thermal and conduction performance but lacks automotive qualification, while MBR30H150CT guarantees AEC-Q101 out-of-box at a slight thermal cost - making MBRF30150CT the balanced choice for industrial applications needing optional qualification and proven field reliability.

FAQ
What is the pin configuration of the MBRF30150CT?
The MBRF30150CT uses a three-terminal ITO-220AB package with a common-cathode dual-die structure: Tab = Anode 1, Lead 1 = Anode 2, Lead 2 = Common Cathode. Polarity is marked on the device body. This configuration supports independent anode routing while sharing a single output node - ideal for center-tapped transformer or dual-output converter designs.
Is the MBRF30150CT AEC-Q101 qualified?
The base MBRF30150CT is not AEC-Q101 qualified; however, the AEC-Q101 version is available as MBRF30150CTH. Both share identical electrical and thermal specifications, but only the 'H' suffix variant undergoes automotive-grade stress testing per AEC-Q101 Rev D. For automotive under-hood applications, MBRF30150CTH must be specified explicitly.
What is the maximum forward voltage drop of the MBRF30150CT at full load?
The MBRF30150CT has a maximum forward voltage drop of 1.05 V per diode at 30 A and 25°C ambient, and 0.92 V per diode at 30 A and 125°C junction temperature. These values are measured under pulsed conditions (PW = 0.3 ms) and define worst-case conduction loss for thermal and efficiency calculations in the MBRF30150CT's target applications.
Can the MBRF30150CT replace the MBRF30100CT in an existing design?
Yes, the MBRF30150CT can replace the MBRF30100CT in most cases because both share identical package (ITO-220AB), pinout, thermal characteristics (RθJC = 4°C/W), and current ratings (IF = 30 A, IFSM = 200 A). The only difference is higher VRRM (150 V vs. 100 V), which provides additional voltage margin - no layout or thermal changes are needed for the MBRF30150CT substitution.
What is the reverse leakage current specification for the MBRF30150CT at elevated temperature?
The MBRF30150CT specifies a maximum reverse leakage current of 10 mA per diode at 150°C junction temperature and rated VRRM (150 V). At 25°C, leakage is limited to 200 µA per diode. This elevated-temperature leakage value is critical for standby power budgeting in always-on industrial systems where the MBRF30150CT may operate near its thermal limit.
