Product details

Overview

MBR3035PT from Diodes Incorporated is a 35V, 30A dual common-cathode Schottky barrier rectifier in TO-3P package, optimized for low forward voltage drop (0.72V @ 30A, 25°C), high surge capability (200A), and thermal efficiency (R_θJC = 1.4°C/W). It serves as a primary output rectifier in high-frequency DC/DC converters and free-wheeling diode in motor drive inverters.

For engineers reviewing the MBR3035PT datasheet, MBR3035PT pinout, MBR3035PT application, or MBR3035PT equivalent, key selection criteria include its 35V V_RRM, 30A I_O rating at T_C = 125°C, 0.72V forward drop at full load, 200A non-repetitive surge current, and TO-3P thermal performance for industrial power supplies and UPS systems.

Technical Context

This dual-element Schottky rectifier uses guard ring die construction to enhance transient protection and reduce leakage under high dv/dt conditions. Its low R_θJC (1.4°C/W) enables direct heatsink mounting without thermal interface pads in high-power density designs.

The device operates across –65°C to +150°C junction temperature range with 500pF typical junction capacitance at 1MHz/4V reverse bias, supporting switching frequencies up to several hundred kHz in SMPS topologies while maintaining low EMI generation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	35 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in 24V–32V DC bus applications.
I_O	30 A - Average rectified output current at T_C = 125°C; supports continuous 30A conduction per element in thermally managed layouts.
V_F @ 30A, 25°C	0.72 V - Low forward voltage drop reduces conduction loss to ~21.6W per element at full load, improving system efficiency.
I_FSM	200 A - Peak non-repetitive surge current (8.3ms half-sine); withstands motor startup surges and capacitor charging transients.
R_θJC	1.4 °C/W - Junction-to-case thermal resistance; enables ≤42°C temperature rise at 30A with 60°C heatsink, simplifying thermal design.
C_T	500 pF - Total junction capacitance at 1MHz/4V; limits high-frequency displacement current and aids EMI control in fast-switching circuits.

Pinout & Package

TO-3P molded plastic package (UL 94V-0 rated) with tin-plated leads; case weight ≈5.6g; polarity marked on body; designed for bolt-down heatsink mounting via central mounting hole (K: Ø2.9–3.65mm).

Pin/Terminal	Circuit Role	Design Meaning
Anode 1 (A1)	Input terminal for first rectifier element	Accepts AC or switched input; connects to transformer secondary or H-bridge leg in full-wave configurations.
Anode 2 (A2)	Input terminal for second rectifier element	Enables dual-channel rectification or independent freewheeling paths in interleaved or multi-output designs.
Cathode (K)	Common output node for both elements	Provides single low-impedance return path; must be directly heatsinked to manage 60W+ total dissipation at full load.

Key Features

Feature	Design Value
Guard ring die construction	Improves ruggedness against voltage transients and prevents edge breakdown during fast dv/dt events in inverter outputs.
Low forward voltage drop	0.72V @ 30A/25°C reduces conduction losses by >30% vs. comparable silicon rectifiers, lowering thermal stress.
High surge capability	200A I_FSM supports repeated motor stall currents and inrush events without degradation in industrial drives.
TO-3P thermal interface	1.4°C/W R_θJC allows direct metal-to-metal heatsinking-no thermal pad required for ≤30A continuous operation.

Applications

Switch-Mode Power Supply Output Rectification

Motor Drive Freewheeling Diode

Use Scenario: Primary DC output rectification in 24V/30A telecom and server PSUs operating at 100–500kHz.

IC Role / Device Role / Timing Role: Dual common-cathode Schottky rectifier replacing two discrete diodes; handles bidirectional current flow in synchronous rectifier auxiliary paths.

Use Value: 0.72V V_F cuts conduction loss by 4.5W per element vs. legacy 0.85V parts, enabling 92%+ efficiency at full load.

Use Scenario: Freewheeling path for 3-phase BLDC motor drivers in HVAC blowers and industrial pumps.

IC Role / Device Role / Timing Role: Clamp inductive kickback during PWM turn-off; conducts only during off-time of upper FETs in half-bridge legs.

Use Value: 200A I_FSM safely absorbs 150A motor stall surges; 500pF C_T minimizes capacitive coupling noise into gate drive signals.

Solar Microinverter DC Link Protection

Redundant Polarity Protection

Use Scenario: Reverse-polarity and overvoltage clamping in 35V-rated PV string interfaces with MPPT controllers.

IC Role / Device Role / Timing Role: Bidirectional blocking element in series with DC input; conducts only during fault conditions or reverse connection.

Use Value: 35V V_RRM matches nominal PV string voltage; guard ring structure sustains >10kV/µs dv/dt during lightning-induced transients.

Use Scenario: Input polarity safeguard in battery-powered test equipment accepting 24V ±10% inputs.

IC Role / Device Role / Timing Role: Series-connected Schottky in positive rail; blocks reverse current while adding <0.75V dropout under normal operation.

Use Value: 0.75V V_F @ 30A/125°C ensures <22.5W dissipation even at elevated ambient, avoiding thermal shutdown.

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-30CPH03-M3	30A/30V, TO-247AC package, R_θJC = 1.5°C/W, V_F = 0.57V @ 30A/25°C	Lower V_F but 5V lower blocking voltage; unsuitable for 35V bus designs	Select when 30V max system voltage and ultra-low loss dominate; avoid if 35V margin required.
ON Semiconductor MBR30H35CT	30A/35V, TO-220AB package, R_θJC = 2.0°C/W, V_F = 0.75V @ 30A/25°C	Same voltage rating but higher thermal resistance; requires larger heatsink area	Choose for cost-sensitive, lower-power (<20A) designs where TO-220 footprint is preferred.

Compared with VS-30CPH03-M3 and MBR30H35CT, MBR3035PT delivers optimal balance of 35V blocking, 30A capacity, and 1.4°C/W thermal resistance in TO-3P-enabling compact, high-efficiency 30A rectification without derating.

FAQ

Is MBR3035PT still in active production?

No-MBR3035PT is officially discontinued per Diodes Incorporated's DS23017 Rev. 9 (July 2015). It remains available through authorized distributors' remaining inventory and Aetrix Electronics' legacy component program with full traceability and extended lifecycle support.

Can MBR3035PT replace MBR3040PT in a 40V design?

No-MBR3035PT has a 35V V_RRM rating and must not be used in 40V applications. Its maximum working peak reverse voltage is 35V; exceeding this risks catastrophic avalanche failure. Use MBR3040PT (40V) or MBR3045PT (45V) for 40V-rated systems.

What is the recommended heatsink mounting method for TO-3P?

Mount using a flat, grounded aluminum heatsink with thermal compound and M3.5 screw through the central K-dimension hole (Ø2.9–3.65mm). Ensure case flatness ≤0.05mm and torque ≤0.5 N·m to maintain uniform thermal contact and avoid package cracking.

Does MBR3035PT meet RoHS and halogen-free requirements?

Yes-MBR3035PT features lead-free finish and complies with EU RoHS Directive 2011/65/EU. It is also Diodes Incorporated "Green" qualified: antimony- and halogen-free per their specification AP02008, with UL 94V-0 flammability rating.
