Product details

Overview

MBR3060PT from Diodes Incorporated is a 30A, 60V dual common-cathode Schottky barrier rectifier in TO-3P package, featuring 0.75V forward voltage at 30A/25°C, 200A non-repetitive surge capability, and 1.4°C/W junction-to-case thermal resistance. It is used for polarity protection and free-wheeling in low-voltage DC-DC converters and industrial power supplies.

For engineers reviewing the MBR3060PT datasheet, MBR3060PT pinout, MBR3060PT application, or MBR3060PT equivalent, key selection criteria include its 60V blocking rating, low V_F at high current, TO-3P thermal performance, and RoHS-compliant tin-plated leads for lead-free assembly.

Technical Context

This device integrates two Schottky diodes in a single TO-3P thermally optimized package with common-cathode configuration, enabling dual-channel rectification without discrete paralleling. Its guard ring die construction provides transient overvoltage robustness, while the 500pF typical junction capacitance supports high-frequency switching up to several hundred kHz.

The 1.4°C/W R_θJC enables direct heatsink mounting for sustained 30A conduction at T_C = 125°C, and the 10,000 V/µs dV/dt rating ensures reliable operation during fast-switching transients in inductive load circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	60 V - Maximum repetitive reverse voltage; defines safe DC blocking limit in polarity protection or freewheeling paths.
I_O	30 A - Average rectified output current at T_C = 125°C; specifies continuous conduction capability with proper heatsinking.
V_FM	0.75 V @ 30A, 25°C - Low forward drop reduces conduction loss and improves efficiency in 12–48V power rails.
I_FSM	200 A - Peak surge current (8.3ms half-sine); withstands motor startup or capacitor inrush without failure.
R_θJC	1.4 °C/W - Junction-to-case thermal resistance; enables precise heatsink sizing for thermal management in enclosed power modules.
C_T	500 pF - Typical junction capacitance at 1 MHz / 4V; impacts high-frequency switching noise and EMI filter design.

Pinout & Package

Package: TO-3P molded plastic case (UL 94V-0), with tin-plated leads, 5.6g mass, and center-tab cathode configuration. Mounting requires insulating washer when heatsink is grounded.

Pin/Terminal	Circuit Role	Design Meaning
Anode 1 (Lead 1)	Input terminal for first diode	Accepts positive input in dual-output or split-rail freewheeling configurations.
Anode 2 (Lead 2)	Input terminal for second diode	Enables independent current paths or parallel operation with shared cathode.
Cathode (Tab)	Common output node	Electrically connected to metal tab; must be electrically isolated from chassis unless system ground reference permits.

Key Features

Feature	Design Value
Guard ring die construction	Enhances transient voltage immunity without external TVS, reducing BOM count in 24V industrial controls.
Low V_F at high current	0.75V @ 30A/25°C minimizes power dissipation (22.5W max) versus silicon rectifiers (>1.1V), lowering heatsink requirements.
High surge rating	200A I_FSM supports repeated inductive turn-off events in solenoid drivers and relay interfaces.
TO-3P thermal performance	1.4°C/W R_θJC allows full 30A rating with modest heatsinking-critical for space-constrained 3U rack power supplies.

Use Scenario: Clamp path for back-EMF energy recovery in brushed DC motor H-bridge drives.

IC Role / Device Role: Bidirectional freewheeling diode pair handling 30A peak inductive current.

Use Value: 200A surge rating absorbs repeated motor commutation spikes without degradation over 100k+ cycles.

Polarity Protection Circuit

Industrial Power Supply Input Stage

Use Scenario: Reverse-voltage blocking at main DC input of programmable logic controllers (PLCs) and I/O modules.

IC Role / Device Role: High-current input protection diode preventing damage from miswired 24V field wiring.

Use Value: 60V V_RRM accommodates 24V nominal systems with 30% line tolerance and transient overshoot per IEC 61000-4-5.

Use Scenario: Bulk rectification in DIN-rail mounted 48V telecom or factory automation PSUs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-30CPH06	Same 60V V_RRM, 30A I_O, but TO-247AC package; R_θJC = 1.5°C/W; slightly higher V_F (0.77V @ 30A).	Compatible in heatsink-mounted freewheeling roles, but requires different mounting hardware due to TO-247 footprint.	Select when existing TO-247 heatsink infrastructure exists and minor V_F increase is acceptable.
ON Semiconductor MBR30H60CT	60V V_RRM, 30A I_O, TO-247 package; V_F = 0.73V @ 30A/25°C; R_θJC = 1.6°C/W; no guard ring noted in datasheet.	Suitable for general-purpose rectification but lacks documented transient hardening for harsh industrial environments.	Prefer for cost-sensitive, non-transient-heavy applications where thermal margin exceeds 1.4°C/W requirement.

Compared with VS-30CPH06 and MBR30H60CT, the MBR3060PT offers superior transient robustness via guard ring design and marginally better thermal resistance-making it preferred for DIN-rail PLC power inputs and motor drive clamps where reliability under surge stress is critical.

FAQ

Is MBR3060PT still in active production?

No-Diodes Incorporated officially discontinued the MBR3060PT as of July 2015 (DS23017 Rev. 9-4). However, Aetrix Electronics maintains legacy inventory with full traceability and offers lifecycle coordination support for ongoing production programs requiring this specific TO-3P dual Schottky configuration.

Can MBR3060PT replace MBR3050PT in existing designs?

Yes-both share identical TO-3P package, pinout, and thermal characteristics; the only difference is V_RRM (60V vs. 50V). Substituting MBR3060PT provides 10V additional reverse margin without layout or thermal changes, making it a safe drop-in upgrade for 24V systems exposed to line transients.

What is the maximum operating temperature for continuous 30A conduction?

The MBR3060PT supports 30A average forward current only when case temperature (T_C) is held at ≤125°C, as defined in Fig. 1 of DS23017. At T_C = 100°C, derated current is ~34A; at T_C = 25°C, it exceeds 45A-but practical limits are set by heatsink capability and system airflow.

Does the TO-3P package require electrical isolation from the heatsink?

Yes-the metal tab is the common cathode terminal and is electrically live during operation. Direct mounting to a grounded heatsink creates a short circuit. An insulating pad (e.g., mica or polymer film) plus shoulder washer must be used unless the system design intentionally references the cathode to chassis ground.
