Product details
Overview
MBR2560CT from Diodes Incorporated is a 60V, 30A dual common-cathode Schottky barrier rectifier in TO-220AB package, featuring 0.75V forward voltage at 30A/25°C and 1.0mA reverse leakage at rated DC blocking voltage, used for polarity protection and freewheeling in low-voltage DC-DC converters and industrial power supplies.
For engineers reviewing the MBR2560CT datasheet, MBR2560CT pinout, MBR2560CT application, or MBR2560CT equivalent, key selection criteria include peak repetitive reverse voltage (60V), average rectified output current (30A @ TC=130°C), thermal resistance junction-to-case (1.5°C/W), and low VF for high-efficiency switching power stages.
Technical Context
This dual-diode Schottky rectifier employs guard ring die construction to enhance transient surge immunity and supports high-frequency operation with typical total capacitance of 500pF per element at 1.0MHz and 4.0V reverse bias. Its low forward voltage drop minimizes conduction losses in continuous-current freewheeling paths.
The device operates across –65°C to +175°C junction temperature range and sustains non-repetitive peak forward surge current up to 150A (8.3ms half-sine), making it suitable for inductive load switching with high di/dt stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum peak repetitive reverse voltage before breakdown; defines safe DC blocking capability in polarity protection circuits |
| IO | 30 A @ TC = +130°C - Continuous average forward current rating when case is heatsinked; sets minimum heatsink requirement |
| VF | 0.75 V @ IF = 30A, TC = +25°C - Low conduction loss enables >92% efficiency in 12V-output synchronous rectifier replacements |
| IRM | 1.0 mA @ VR = 60V, TC = +25°C - Reverse leakage limits standby power loss in always-on systems |
| RθJC | 1.5 °C/W - Thermal resistance from junction to case; determines temperature rise per watt dissipated under heatsink mounting |
| IFSM | 150 A (8.3ms) - Surge withstand capability ensures reliability during motor startup or capacitor charging transients |
Pinout & Package
TO-220AB package with isolated metal tab (cathode common), plastic-molded body (UL 94V-0), and bright tin-plated terminals. Pin 1 and Pin 3 are anodes; Pin 2 is common cathode (case-connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Input terminal for first Schottky diode element; connects to switched high-side node in dual-path freewheeling |
| Pin 2 | Common Cathode | Shared cathode tied to heatsink-mountable metal tab; provides low-inductance return path and thermal conduction |
| Pin 3 | Anode 2 | Input terminal for second Schottky diode element; enables independent control of two power rails or phases |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Improves ESD and transient surge immunity without requiring external TVS components in 24V industrial inputs |
| Low VF at high current | 0.75V @ 30A reduces power dissipation by ~4W vs. silicon rectifiers, lowering heatsink size in compact 50W adapters |
| High surge capability | 150A IFSM rating supports reliable operation during 100ms inrush events in motor drive DC bus clamping |
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling and HTRB, enabling use in under-hood power modules |

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-30CPH06 | Same 60V VRRM, 30A IO, but VF = 0.71V @ 30A/25°C; TO-247AC package with higher RθJC (1.8°C/W) | Requires larger heatsink due to higher thermal resistance; better suited for lower ambient temperature environments | Select when lowest possible VF is critical and board space permits TO-247 footprint |
| ON Semiconductor MBR3060CT | Identical electrical specs and TO-220AB package; VF = 0.75V @ 30A/25°C, IR = 1.0mA @ 60V/25°C | Drop-in mechanical and electrical replacement; same marking, pinout, and thermal profile | Preferred for second-source procurement where identical form-fit-function is required |
Compared with VS-30CPH06, MBR2560CT offers lower thermal resistance for denser layouts; versus MBR3060CT, it shares identical performance but differs in traceability and qualification history-Diodes' AEC-Q101 validation adds assurance for automotive designs.

FAQ
What is the maximum junction temperature for continuous operation?
The MBR2560CT has an operating junction temperature range of –65°C to +175°C. For continuous operation at rated 30A current, the case temperature must be maintained at ≤+130°C per the derating curve, requiring adequate heatsinking to limit junction temperature rise based on RθJC = 1.5°C/W.
Is the metal tab electrically isolated from the pins?
No-the metal tab (Pin 2) is the common cathode and is electrically connected to the internal cathode structure. It is not isolated and must be treated as a live terminal; mounting to a grounded heatsink establishes the cathode reference potential for both diode elements.
How does the guard ring construction improve reliability?
The guard ring die structure surrounds the active junction to suppress edge breakdown under high dv/dt or ESD stress. This design increases the device's ability to survive repetitive 1.0kV HBM ESD events and 40A surge currents without parameter shift, extending field life in noisy industrial environments.
Can MBR2560CT replace MBR2545CT in existing designs?
Yes-both share identical TO-220AB package, pinout, and thermal characteristics. The MBR2560CT's higher 60V VRRM provides additional margin over the 45V MBR2545CT, with only minor VF increase (0.82V → 0.75V at 30A/25°C), making it a safe upgrade for designs operating below 45V reverse stress.
