Diodes Incorporated MBR10150CTP

Overview

MBR10150CTP from Diodes Incorporated is a 10A dual common-cathode Schottky barrier rectifier in ITO-220S package, rated for 150V peak reverse voltage, 5A average current per leg, 0.91V forward voltage at 5A/25°C, and 2000V isolation between heatsink tab and cathode - used in high-efficiency AC/DC secondary-side rectification for industrial power supplies.

For engineers reviewing the MBR10150CTP datasheet, MBR10150CTP pinout, MBR10150CTP application, or MBR10150CTP equivalent, key selection criteria include per-leg thermal resistance (3°C/W), soft fast switching behavior, UL 1557 certification, isolated heatsink tab, and derating curve compliance for ambient temperatures up to 125°C.

Technical Context

This dual Schottky rectifier integrates two independent 5A anode legs sharing a common cathode terminal, enabling synchronous or interleaved secondary-side rectification. Its ITO-220S package features an electrically isolated heatsink tab rated for 2000V AC isolation, supporting direct mounting to grounded chassis without additional insulation.

The device operates across –65°C to +175°C junction temperature range with typical VF of 0.75V at 5A/125°C and IR ≤20µA at 150V/125°C, making it suitable for thermally constrained high-frequency SMPS designs where low conduction loss and minimal reverse recovery charge are critical.

Key Specifications

Pinout & Package

Package: ITO-220S - molded plastic case with electrically isolated metal heatsink tab (UL 94V-0), matte tin-plated copper leadframe, 1.335g mass, and standardized 4-pin footprint optimized for vertical PCB mounting and mechanical heat transfer.

FAQ

Is MBR10150CTP still in active production?

No - Diodes Incorporated officially discontinued MBR10150CTP as of October 2015. It is marked "OBSOLETE – PART DISCONTINUED" in the official datasheet (DS31499 Rev. 10-4). Aetrix Electronics maintains limited legacy stock with full traceability and offers lifecycle support for existing designs.

Can MBR10150CTP be replaced with MBR10150 in the same PCB footprint?

No - MBR10150 uses TO-220AB packaging with a non-isolated tab, while MBR10150CTP uses ITO-220S with an electrically isolated tab and different pinout (4-pin vs. 3-pin). Mechanical and electrical incompatibility prevents direct replacement without board redesign.

What is the significance of the "CTP" suffix in MBR10150CTP?

The "CTP" suffix denotes the ITO-220S package variant with electrically isolated heatsink tab (C), tape-and-reel or tube packaging (T), and Diodes' proprietary process and testing (P). This distinguishes it from non-isolated TO-220 variants like MBR10150G or MBR10150CT.

Does MBR10150CTP require external thermal interface material when mounted to a heatsink?

No - the ITO-220S package's heatsink tab is electrically isolated and designed for direct metal-to-metal contact with grounded heatsinks or chassis. No insulating pad or thermal tape is needed, though thermally conductive grease may be applied to improve interfacial thermal transfer.
