Product details
Overview
MBR30150CT-Y from Taiwan Semiconductor is a 30A, 150V dual-die Schottky barrier rectifier in TO-220AB package, featuring 1.02V max forward voltage at 30A/25°C and 5mA max reverse leakage at 150V/125°C, optimized for high-efficiency DC-DC converters and industrial SMPS.
For engineers reviewing the MBR30150CT-Y datasheet, MBR30150CT-Y pinout, MBR30150CT-Y application, or MBR30150CT-Y equivalent, key selection criteria include its 150V VRRM rating, 200A IFSM surge capability, 1.5°C/W junction-to-case thermal resistance, and dual-common-cathode configuration for center-tapped transformer rectification.
Technical Context
This device integrates two independent Schottky diodes in a single TO-220AB package with common cathode connection, enabling full-wave rectification without external wiring. Its low forward voltage (≤1.02V @ 30A/25°C) reduces conduction loss, while guard ring structure enhances overvoltage ruggedness.
The MBR30150CT-Y operates across -55°C to +150°C junction temperature range and supports 10,000 V/μs dv/dt rating, making it suitable for fast-switching topologies where reverse recovery time is critical-Schottky architecture ensures near-zero reverse recovery charge.
Key Specifications

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-M3 | Same 150V VRRM, 30A IF, TO-247AC package; 1.05V VF @ 30A/25°C; higher RθJC (2.0°C/W) | Requires larger heatsink due to higher thermal resistance; better suited for forced-air-cooled systems | Select when board space permits TO-247 footprint and airflow supports higher thermal impedance |
| ON Semiconductor MBR30H150CT | Identical TO-220AB package and pinout; 1.00V VF @ 30A/25°C; 10mA IR @ 150V/125°C (vs. 5mA) | Slightly higher leakage may affect ultra-low-power standby modes; otherwise functionally interchangeable | Preferred for drop-in replacement where leakage sensitivity is not critical and same mechanical fit is required |
Compared with MBR30150CT-Y, the VS-30CPH15-M3 trades thermal performance for higher surge margin in TO-247, while the MBR30H150CT offers tighter VF but relaxed IR spec-both require validation of thermal interface and leakage impact in final design.

FAQ
What is the maximum junction temperature rating for the MBR30150CT-Y?
The MBR30150CT-Y has a maximum junction temperature (TJ) rating of +150°C, with operational range from -55°C to +150°C. This allows reliable use in high-ambient environments such as enclosed power supplies or industrial control cabinets, provided thermal design maintains junction temperature within this limit using the specified 1.5°C/W RθJC value.
Does the MBR30150CT-Y have a common-cathode or common-anode configuration?
The MBR30150CT-Y uses a common-cathode configuration: Pin 2 is the shared cathode, while Pins 1 and 3 are independent anodes. This arrangement supports full-wave rectification from center-tapped transformers or dual-phase synchronous rectifier circuits without external interconnection, simplifying PCB layout versus discrete diode solutions.
What is the forward voltage specification for MBR30150CT-Y at elevated temperature?
At 30A and 125°C junction temperature, the MBR30150CT-Y exhibits a maximum forward voltage of 0.98V. This lower VF at high temperature-compared to 1.02V at 25°C-reflects the negative temperature coefficient of Schottky diodes and improves thermal stability during sustained high-load operation.
Is the MBR30150CT-Y RoHS and halogen-free compliant?
Yes, the MBR30150CT-Y is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated for solderability per J-STD-002-ensuring compliance with environmental directives for industrial, telecom, and consumer end equipment.
What packaging format is used for MBR30150CT-Y shipments?
MBR30150CT-Y is supplied in tubes containing 50 units each. The TO-220AB package features a metal tab that is electrically isolated from all pins, allowing direct heatsink mounting without insulating hardware-critical for thermal management in high-power rectifier applications.
