Product details
Overview
MBR20150CTP from Diodes Incorporated is a 20A dual common-cathode Schottky barrier rectifier in ITO-220S package, rated for 150V peak reverse voltage, 10A average current per leg, 0.9V max forward voltage at 10A/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 MBR20150CTP datasheet, MBR20150CTP pinout, MBR20150CTP application, or MBR20150CTP equivalent, key selection criteria include thermal resistance (3°C/W junction-to-case), soft fast switching behavior, UL 1557 certification, and electrically isolated heatsink tab for simplified thermal design in high-density power converters.
Technical Context
This dual-anode Schottky rectifier integrates two independent 10A legs sharing a common cathode terminal, enabling synchronous or interleaved secondary-side rectification. Its low VF (≤0.9V @10A) and soft recovery minimize conduction loss and EMI in 50–100kHz SMPS designs.
The ITO-220S package features an electrically isolated metal tab (2000V AC isolation), allowing direct mounting to grounded heatsinks without insulation hardware. Thermal resistance of 3°C/W (junction-to-case) supports sustained 20A total output with proper heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum non-repetitive reverse voltage each leg withstands without breakdown |
| IO (per leg) | 10 A - Continuous average forward current per anode under 25°C ambient with adequate heatsinking |
| VF (max) | 0.9 V @ 10A, 25°C - Directly determines conduction loss (≤9W per leg at full load) |
| RθJC | 3 °C/W - Enables precise junction temperature estimation when heatsink thermal resistance is known |
| VAC (isolation) | 2000 V - Allows safe mounting to chassis-grounded heatsinks without insulating pads |
| IFSM | 105 A - Peak surge rating for 8.3ms half-sine, supporting inrush current handling in offline supplies |
| TJ range | −65 to +175 °C - Supports operation in extended-temperature industrial environments |
Pinout & Package
Package: ITO-220S - Molded plastic case with electrically isolated metal tab (UL 94V-0), matte tin-plated copper leadframe, 1.335g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode A) | First anode connection | Independent input for first rectifier leg; wired to transformer secondary winding A |
| 2 (Common Cathode) | Shared cathode node | Output node for both legs; connects to +VOUT rail and bulk capacitor positive |
| 3 (Anode B) | Second anode connection | Independent input for second rectifier leg; wired to transformer secondary winding B |
| 4 (Heatsink Tab) | Electrically isolated thermal interface | Mounting surface for heatsink; 2000V AC isolation from cathode enables direct chassis grounding |
Key Features
| Feature | Design Value |

FAQ
Is MBR20150CTP still in active production?
No - Diodes Incorporated has officially discontinued MBR20150CTP (OBSOLETE status per DS31498 Rev. 10). It is no longer manufactured, and no new wafers are being produced. Aetrix Electronics offers remaining genuine stock with full traceability and supports transition planning to active alternatives.
What is the functional replacement for MBR20150CTP?
Diodes recommends MBR20150 in alternate packages (e.g., TO-220AB or TO-263) as the nearest functional replacement. These share identical electrical specs (150V VRRM, 10A/leg IO, 0.9V VF) but lack the electrically isolated tab - requiring insulated mounting hardware if used in the same thermal layout.
Can MBR20150CTP be used in place of standard TO-220 Schottky rectifiers?
Yes, but only with attention to pin compatibility and isolation requirements. Pin 1–3 match TO-220AB (A-K-A), but Pin 4 (isolated tab) adds mounting flexibility. Substituting into non-isolated designs requires verifying creepage/clearance and thermal interface design due to the extra tab terminal.
Why does MBR20150CTP have four terminals instead of three?
The fourth terminal is the electrically isolated heatsink tab (Pin 4), rated for 2000V AC isolation from the common cathode (Pin 2). This enables direct mechanical attachment to grounded metal chassis without insulating hardware - a key differentiator versus standard TO-220 devices.
