Product details
Overview
MBR6045PT-F from Diodes Incorporated is a 60A, 45V Schottky barrier rectifier in TO-3P package, designed for high-efficiency low-voltage DC output stages in switching power supplies and DC-DC converters. It features 0.75V forward voltage at 60A/25°C, 500A non-repetitive surge capability, and 1.0°C/W junction-to-case thermal resistance for heatsink-mounted operation.
For engineers reviewing the MBR6045PT-F datasheet, MBR6045PT-F pinout, MBR6045PT-F application, or MBR6045PT-F equivalent, key selection criteria include forward voltage drop at rated current, thermal resistance under forced convection, surge current rating for inductive load commutation, and RoHS-compliant tin-plated leads for lead-free reflow compatibility.
Technical Context
This device uses guard-ring Schottky barrier die construction to suppress transient-induced avalanche breakdown, enabling robust operation in freewheeling and polarity protection circuits. Its low VF and high IO support high-frequency (≥100 kHz) inverters where conduction loss dominates efficiency.
The 650 pF typical junction capacitance at 4V reverse bias and -55°C to +150°C operating range allow stable performance in automotive under-hood and industrial motor drive environments with rapid thermal cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 45 V - Maximum repetitive reverse voltage before breakdown; sets upper limit for DC blocking in 36V nominal systems. |
| IO @ TC=125°C | 60 A - Continuous average forward current when case temperature is held at 125°C via heatsink; defines thermal design margin. |
| VFM @ 60A, 25°C | 0.75 V - Forward voltage at full rated current; directly determines conduction loss (45W at 60A) and heatsink sizing. |
| IFSM (8.3ms) | 500 A - Peak non-repetitive surge current; supports motor startup and inductive load turn-off without failure. |
| RJC | 1.0 °C/W - Junction-to-case thermal resistance; enables calculation of junction temperature rise above heatsink temperature. |
| CT @ 1MHz, 4V | 650 pF - Junction capacitance affecting high-frequency switching noise and EMI filter design in SMPS outputs. |
Pinout & Package
TO-3P package: 3-terminal isolated metal tab (cathode), molded plastic body with UL 94V-0 flammability rating, bright tin-plated leads solderable per MIL-STD-202 Method 208. Polarity marked on body; cathode tab electrically connected to case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input terminal for forward conduction | Connected to input rail or switch node; carries full load current during conduction phase. |
| Cathode (Metal Tab) | Output terminal and thermal path | Electrically and thermally coupled to heatsink; must be insulated from chassis if floating output required. |
| Anode (Lead 2) | Redundant anode connection | Dual-anode configuration reduces lead inductance and improves current sharing in high-di/dt applications. |
Key Features
| Feature | Design Value |
|---|---|
| Guard-ring Schottky die | Suppresses edge avalanche during voltage transients, eliminating need for external snubbers in 48V bus protection. |
| Low VF at high current | 0.75V @ 60A/25°C reduces conduction loss by ≥30% vs. comparable silicon rectifiers in 12–48V DC-DC outputs. |
| High IFSM | 500A surge rating supports 10× rated current for 8.3ms, enabling use in UPS battery charging circuits with high inrush. |
| RoHS-compliant finish | Bright tin plating meets JEDEC J-STD-020C Level 1 moisture sensitivity and lead-free reflow profiles up to 260°C. |
Applications
| Server Power Supply Output Rectification | Industrial Motor Drive Freewheeling |
|---|---|
Use Scenario: 48V intermediate bus rectification in 1U server PSUs operating at 200–500 kHz switching frequency. IC Role / Device Role / Timing Role: Primary output rectifier replacing synchronous MOSFETs where gate drive complexity outweighs efficiency gain. Use Value: 0.75V VF limits conduction loss to 45W at full 60A load, reducing heatsink volume by 40% vs. 1.1V Si diodes. | Use Scenario: Bidirectional energy recovery path across 3-phase IGBT bridges in servo drives with regenerative braking. IC Role / Device Role / Timing Role: Freewheeling diode clamping inductive kickback during IGBT turn-off. Use Value: 500A IFSM withstands 3× motor stall current surges without degradation, extending field reliability beyond 10 years. |
| Solar Charge Controller Polarity Protection | Telecom DC Distribution Block |
Use Scenario: Reverse-polarity safeguard between PV array and MPPT controller in off-grid solar installations. IC Role / Device Role / Timing Role: Unidirectional blocking element preventing battery discharge into shorted panel strings. Use Value: 45V VRRM provides 20% margin over 36V nominal battery banks, while 1.0°C/W RJC enables passive cooling in sealed enclosures. | Use Scenario: Input protection diode in -48V telecom rack distribution units handling multiple hot-swap modules. IC Role / Device Role / Timing Role: OR-ing diode isolating redundant power feeds while minimizing voltage drop. Use Value: 0.55V VF @ 30A/125°C maintains ≤1.65V total drop across dual-path architecture, preserving system voltage margin. |
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-60CPH045 | 45V VRRM, 60A IO, but 0.82V VF @ 60A/25°C and 1.2°C/W RJC | Higher conduction loss and thermal resistance require larger heatsink in space-constrained telecom designs | Select when legacy Vishay footprint compatibility is required and 7% higher VF is acceptable |
| ON Semiconductor MBR6045CT | Same 45V/60A rating but TO-247AC package with single-anode lead; 0.72V VF @ 60A/25°C | Lacks dual-anode configuration, limiting di/dt handling in high-frequency inverter freewheeling | Prefer for cost-sensitive industrial supplies where TO-247 mounting simplifies assembly |
Compared with VS-60CPH045 and MBR6045CT, the MBR6045PT-F delivers lower thermal resistance and dual-anode layout for superior surge immunity-critical in high-reliability 48V server and motor control applications where heatsink real estate and transient robustness are constrained.

FAQ
Is MBR6045PT-F still in production?
No-MBR6045PT-F is officially obsolete and discontinued per Diodes Incorporated's DS30053 Rev. 5 (July 2015). Aetrix Electronics holds remaining authorized inventory with full traceability and offers last-time-buy support including extended warranty and documentation packages.
What is the maximum allowable case temperature for continuous 60A operation?
The datasheet specifies 60A average forward current only at TC = 125°C. Sustained operation at this current requires active heatsinking to maintain case temperature at or below 125°C; junction temperature must not exceed 150°C under any condition.
Can MBR6045PT-F replace MBR6040PT in existing designs?
Yes-MBR6045PT-F shares identical TO-3P package, pinout, and thermal characteristics with MBR6040PT, differing only in VRRM (45V vs. 40V). The 5V higher blocking voltage provides additional margin in 36V systems subject to line transients or ripple overshoot.
Does the metal tab serve only as cathode or also as thermal interface?
The metal tab is both the cathode terminal and primary thermal interface. It must be electrically isolated from the heatsink using mica or polymer insulators unless the circuit topology permits direct cathode-to-chassis connection; thermal paste is required between tab and heatsink surface for optimal RJC performance.
