Product details

Overview

MBR6045PT from Diodes Incorporated is a 60A, 45V TO-3P-packaged Schottky barrier rectifier with low forward voltage drop (0.75V @ 60A, 25°C), high surge capability (500A IFSM), and thermal resistance of 1.0°C/W - used in high-frequency inverters, free-wheeling diode circuits, and polarity protection for 12–24V DC power rails.

For engineers reviewing the MBR6045PT datasheet, MBR6045PT pinout, MBR6045PT application, or MBR6045PT equivalent, key selection criteria include peak reverse voltage rating (45V), average output current at 125°C case temperature (60A), forward voltage at full load, thermal resistance, and TO-3P mechanical compatibility with heatsink mounting.

Technical Context

This device uses Schottky barrier chip guard ring die construction to suppress transient-induced failure and improve reliability under repetitive surge stress. Its low V_F and high I_O support efficient power conversion in low-voltage, high-current switching topologies.

The junction-to-case thermal resistance (1.0°C/W) enables direct mounting to heatsinks without thermal interface material in many industrial designs, while its 650pF typical capacitance limits high-frequency switching losses in inverter freewheeling paths.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	45 V - Maximum non-repetitive reverse blocking voltage; defines safe operating limit in polarity protection and flyback clamp applications.
I_O @ T_C = 125°C	60 A - Continuous average forward current at 125°C case temperature; sets usable current capacity in thermally constrained enclosures.
V_FM @ 60A, 25°C	0.75 V - Forward voltage at full rated current and room temperature; directly determines conduction loss (45W at 60A).
I_FSM (8.3ms)	500 A - Non-repetitive surge current rating; supports motor startup, capacitor charging, and fault-tolerant design margins.
R_JC	1.0 °C/W - Junction-to-case thermal resistance; enables predictable thermal rise when mounted on standard heatsinks per JEDEC guidelines.
C_T @ 1MHz, 4V	650 pF - Typical junction capacitance; impacts switching speed and EMI in high-frequency rectification above 50kHz.

Pinout & Package

Package: TO-3P - molded plastic case (UL 94V-0), 5.6g weight, tin-plated leads, polarity marked on body. Mounting requires heatsink contact via case back surface.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Tab)	Main current input terminal	Electrically connected to metal tab; must be isolated from chassis unless circuit ground reference permits.
Cathode (Lead)	Main current output terminal	Single lead exiting package; carries full forward current to load or return path.

Key Features

Feature	Design Value
Schottky barrier + guard ring die	Suppresses edge breakdown during voltage transients, extending lifetime in automotive and industrial power supplies.
Low V_F at high current	0.75V @ 60A/25°C reduces conduction loss by ~30% vs. comparable fast recovery diodes, improving system efficiency.
High I_FSM rating	500A surge withstand enables use in motor drive freewheeling without external snubbers or derating.
TO-3P mechanical robustness	UL 94V-0 housing and 1.0°C/W R_JC support reliable operation in high-vibration, high-temperature environments (e.g., rail traction converters).

FAQ

Is MBR6045PT still in production?

No - MBR6045PT is officially obsolete and discontinued per Diodes Incorporated's DS30053 Rev. 5 (July 2015). It is no longer manufactured, but Aetrix Electronics maintains legacy inventory and offers lifecycle management support for existing designs.

What is the correct pin identification for TO-3P mounting?

The metal tab is the anode and must be electrically isolated unless referenced to system ground; the single lead is the cathode. Polarity is marked on the body with a band or "K" symbol adjacent to the cathode lead.

Can MBR6045PT replace MBR6040PT in existing PCB layouts?

Yes - both share identical TO-3P package dimensions, pinout, and thermal footprint. The only electrical difference is V_RRM: 45V vs. 40V. Replacement is acceptable if system reverse voltage never exceeds 40V, but not recommended for 40–45V margin-critical applications.

What thermal interface is required for 60A operation?

No thermal interface material is strictly required due to the 1.0°C/W R_JC, but a thin layer of thermally conductive grease or pad improves contact uniformity. Mounting torque must comply with TO-3P mechanical specs (typically 1.0–1.5 N·m) to avoid case cracking or poor thermal transfer.
