For engineers reviewing the MBRB2560CT-E3/45 datasheet, MBRB2560CT-E3/45 pinout, MBRB2560CT-E3/45 application, or MBRB2560CT-E3/45 equivalent, key selection criteria include its 60 V VRRM, dual common-cathode configuration, thermal resistance of 1.5 °C/W per diode, RoHS-compliant matte tin-plated leads, and suitability for high-frequency freewheeling and polarity protection circuits.
Technical Context
This device integrates two independent Schottky diodes sharing a common cathode terminal, optimized for low-loss unidirectional conduction in high-switching-frequency topologies. Its guardring structure enhances overvoltage ruggedness, while the TO-220AB case provides direct heatsink mounting and thermal dissipation capability up to 150 °C junction temperature.
The MBRB2560CT-E3/45 operates with fast recovery (no stored charge), supports dV/dt up to 10,000 V/μs, and maintains stable reverse leakage (< 40 mA at 125 °C) under blocking conditions - critical for maintaining efficiency in compact, thermally constrained power stages.

Applications
| Switch-Mode Power Supply Output Rectification | DC/DC Converter Freewheeling Diode |
|---|---|
Use Scenario: Used in secondary-side synchronous or asynchronous rectification of isolated flyback or forward converters delivering 12–48 V outputs at 10–30 A. IC Role / Device Role / Timing Role: Dual Schottky rectifier providing low-loss bidirectional current path during switch off-time; common cathode simplifies output filtering. Use Value: 0.73 V VF at full load cuts conduction loss by ~40% versus 1.1 V Si diodes, directly improving efficiency by 1.2–1.8% at 250 kHz switching. | Use Scenario: Placed across inductive windings in buck or boost converters operating at 300–1000 kHz to clamp back-EMF and recirculate current. IC Role / Device Role / Timing Role: Fast-recovery freewheeling element conducting during high-side switch off-phase; dual configuration supports interleaved or redundant paths. Use Value: 150 A IFSM withstands peak inductor current surges; 1.5 °C/W RθJC allows direct heatsink attachment for thermal stability under burst-mode loads. |
| Polarity Protection Circuit | Redundant Power Input OR-ing |
Use Scenario: Installed in series with main power input rail to block reverse battery connection or accidental negative supply insertion in 24 V industrial controllers. IC Role / Device Role / Timing Role: Forward-biased series-blocking diode; common cathode enables single-point grounding of protected system. Use Value: 60 V VRRM provides 2× margin over 24 V nominal; low VF limits voltage drop to < 0.8 V at 15 A, minimizing power loss and heat generation. | Use Scenario: Employed in dual-input power systems (e.g., primary + backup battery) where either source may supply load, requiring automatic source selection without cross-conduction. IC Role / Device Role / Timing Role: Each anode connects to separate input rail; common cathode feeds shared load - functions as passive OR-ing diode pair. Use Value: Matched VF characteristics between diodes ensure balanced current sharing; 12.5 A per diode rating supports ≥25 A total load with derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS2560CG | Same TO-220AB package, 60 V VRRM, but 2 × 12.5 A IF(AV) at TC = 125 °C (not 130 °C); VF = 0.75 V @ 30 A, 125 °C | Marginally lower thermal derating and slightly higher forward drop reduce efficiency in high-ambient designs | Acceptable for space-constrained 24 V systems where 0.02 V VF difference is tolerable and ambient stays ≤ 60 °C |
| ON Semi MURB2560CT | Ultrafast recovery (not Schottky); 60 V VRRM, 2 × 12.5 A IF(AV), but VF = 1.15 V @ 30 A - higher conduction loss | Higher switching losses and EMI due to minority carrier tail; unsuitable for >200 kHz operation | Only consider if cost sensitivity outweighs efficiency needs and thermal budget permits extra 12 W dissipation at 30 A |
Compared with STPS2560CG and MURB2560CT, the MBRB2560CT-E3/45 offers superior thermal margin (130 °C rating), lowest VF, and true Schottky speed - making it optimal for high-efficiency, high-frequency, and thermally demanding DC/DC and SMPS designs.

FAQ
What is the maximum junction temperature rating for MBRB2560CT-E3/45?
The MBRB2560CT-E3/45 has a maximum junction temperature (TJ) of +150 °C, verified per Vishay's datasheet revision 01-Apr-2026. This rating enables reliable operation in high-ambient environments such as enclosed power supplies or industrial motor drives when properly heatsinked. Derating curves confirm usable current capacity down to 0 A at 150 °C case temperature, with full 12.5 A per diode available at TC = 130 °C.
Is MBRB2560CT-E3/45 pin-compatible with MBR2545CT?
No, MBRB2560CT-E3/45 is not pin-compatible with MBR2545CT. While both use TO-220AB packaging and share the same pinout (Anode1–Cathode–Anode2), the MBRB2560CT-E3/45 is a distinct Vishay part with 60 V VRRM, whereas MBR2545CT is rated for 45 V. Substitution requires verification of reverse voltage margin in the target circuit; using MBRB2560CT-E3/45 in place of MBR2545CT is safe, but not vice versa.
Does MBRB2560CT-E3/45 support lead-free soldering processes?
Yes, MBRB2560CT-E3/45 supports lead-free soldering: its matte tin-plated leads comply with J-STD-002 and JESD22-B102, and the package withstands solder bath temperatures up to 275 °C for 10 seconds per JESD22-B106. The E3 suffix confirms RoHS compliance and JESD201 Class 1A whisker resistance - essential for automated assembly in commercial and industrial production.
What is the thermal resistance from junction to case for each diode in MBRB2560CT-E3/45?
The typical thermal resistance from junction to case (RθJC) for each diode in MBRB2560CT-E3/45 is 1.5 °C/W, as specified in Vishay's datasheet Document Number 88675. This value applies per diode under standard mounting conditions (flat metal surface, no thermal interface material assumed) and is critical for calculating junction temperature rise: ΔTJ = PD × 1.5 °C/W, where PD is power dissipated in that diode.
Can MBRB2560CT-E3/45 be used in parallel configurations for higher current handling?
MBRB2560CT-E3/45 is not recommended for parallel operation across devices due to VF mismatch - even within the same batch, forward voltage variation can cause current imbalance and thermal runaway. For higher current, use a single higher-rated device or implement active current-sharing circuitry. Within the same MBRB2560CT-E3/45 unit, the two internal diodes are matched and designed for simultaneous conduction in dual-anode applications.
