Product details
Overview
B260BE-13 from Diodes Incorporated is a 60 V, 2 A surface-mount Schottky barrier rectifier in SMB package, featuring 0.65 V max forward voltage at 2 A and 0.20 mA max reverse leakage at 60 V and +25°C, optimized for boost, blocking, and recirculating diode functions in DC-DC converters and power supplies.
For engineers reviewing the B260BE-13 datasheet, B260BE-13 pinout, B260BE-13 application, or B260BE-13 equivalent, key selection criteria include its low VF for efficiency, high-temperature IR stability up to +150°C, SMB thermal resistance (RθJA = 90°C/W), and RoHS-compliant matte tin terminations.
Technical Context
This Schottky rectifier uses a planar epitaxial construction with low-barrier metal-semiconductor junction to achieve fast switching (no minority-carrier storage) and minimal forward conduction loss. Its design targets continuous-duty rectification in high-frequency switching topologies where thermal management and leakage control are critical.
The device operates across –55°C to +150°C with specified derating above +75°C ambient, and exhibits stable capacitance (75 pF typical at 4 V, 1 MHz) and low RθJC (40°C/W) for effective heat transfer to the PCB pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse voltage before breakdown; sets safe operating limit in 48 V systems and flyback clamp circuits. |
| IO | 2 A - Average rectified output current at TA = +25°C; usable up to ~1.3 A at +100°C per derating curve. |
| VF (max) | 0.65 V @ 2 A, +25°C - Low conduction loss improves converter efficiency and reduces thermal stress on PCB traces. |
| IR (max) | 0.20 mA @ 60 V, +25°C - Tight leakage spec ensures reliability in high-temp hold-up and standby modes. |
| RθJA | 90°C/W - Thermal resistance from junction to ambient on standard FR-4; defines required copper area for thermal compliance. |
| Junction Cap. | 75 pF @ 4 V, 1 MHz - Low capacitance minimizes switching losses and EMI in high-frequency (>100 kHz) applications. |
Pinout & Package
Package: SMB (Surface Mount Small Outline), molded plastic case with UL 94V-0 rating, cathode indicated by band on body. Weight: 0.093 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., switch node in boost); requires adequate copper pour for thermal dissipation. |
| Cathode | Forward current exit / reverse-blocking terminal | Marked with band; ties to higher-potential rail (e.g., output capacitor positive); must withstand full VRRM during off-state. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at 2 A | 0.65 V max enables >92% efficiency in 12 V → 24 V boost stages at full load without active cooling. |
| High-temp IR stability | 0.20 mA @ +25°C and <14.5 mA @ +125°C prevents thermal runaway in enclosed industrial power modules. |
| RoHS & Green compliant | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb) supports environmental compliance in EU and Asia-Pacific markets. |
| SMB thermal performance | RθJC = 40°C/W allows direct heat transfer to internal ground planes, reducing need for external heatsinks in space-constrained designs. |
Applications
| Boost Diode | Blocking Diode |
|---|---|
Use Scenario: Used in non-isolated boost converters to step up 12 V input to 24 V or 48 V output for industrial sensors and LED drivers. IC Role / Device Role: Unidirectional current path enabling energy transfer from inductor to output capacitor during switch-off phase. Use Value: 0.65 V VF minimizes power loss and temperature rise at 2 A peak, extending lifetime in sealed enclosures. | Use Scenario: Prevents reverse current flow from battery backup to main supply in telecom power distribution units. IC Role / Device Role: Isolates secondary power source during primary failure or maintenance, ensuring uninterrupted operation. Use Value: 0.20 mA IR at +25°C and stable leakage up to +125°C avoids battery drain and false fault detection. |
| Recirculating Diode | DC-DC Converter Output Rectifier |
Use Scenario: Provides freewheeling path for inductive loads such as solenoids and relay coils in automotive body control modules. IC Role / Device Role: Clamps inductive kickback voltage and dissipates stored magnetic energy safely during turn-off. Use Value: Fast recovery (Schottky, no Qrr) eliminates voltage spikes >60 V, protecting MOSFET switches and reducing snubber complexity. | Use Scenario: Rectifies synchronous-buck-derived outputs in FPGA power rails requiring tight regulation and low noise. IC Role / Device Role: Secondary-side rectifier in asymmetrical half-bridge or flyback topologies delivering 3.3 V/5 V at up to 2 A. Use Value: 75 pF junction capacitance limits ringing and EMI generation, easing EMC filter design in dense PCB layouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS26 (Micro Commercial) | Same SMB package, 60 V/2 A, VF = 0.75 V max @ 2 A - 150 mV higher than B260BE-13. | Higher VF increases conduction loss by ~75 mW at 2 A, requiring larger thermal pads in high-ambient environments. | Select when cost sensitivity outweighs efficiency targets and thermal margin is ≥15°C. |
| SB260 (ON Semiconductor) | Same SMB package, 60 V/2 A, IR = 0.50 mA @ 60 V/+25°C - 2.5× higher leakage than B260BE-13. | Elevated IR may cause measurable battery drain in always-on backup systems above +85°C. | Select only for non-critical, short-duration applications where leakage-induced standby loss is acceptable. |
Compared with SS26 and SB260, B260BE-13 delivers superior thermal stability and lowest conduction loss in SMB form factor, making it preferred for high-efficiency, long-life industrial and telecom power designs where leakage and VF directly impact system MTBF.

FAQ
What is the maximum junction temperature for continuous operation?
The B260BE-13 has an operating junction temperature range of –55°C to +150°C. Continuous operation at +150°C requires strict adherence to the derating curve: IO drops to approximately 1.0 A at +100°C ambient and further to ~0.6 A at +125°C ambient on standard FR-4 with recommended pad layout.
Is the B260BE-13 suitable for synchronous rectification?
No - B260BE-13 is a passive Schottky rectifier, not a synchronous rectifier IC or MOSFET-based solution. It lacks gate drive interface or control logic. It serves as a freewheeling or output rectifier in non-synchronous topologies where simplicity and cost outweigh efficiency gains from active switching.
Does this part have a specified reverse recovery time (trr)?
No trr is specified because the B260BE-13 is a majority-carrier Schottky device with no minority-carrier storage. Its switching is effectively instantaneous (<1 ns), eliminating reverse recovery loss and associated EMI - confirmed by absence of trr parameter in DS39271 Rev. 4-2.
Can B260BE-13 replace B260AE-13 in existing designs?
Yes, with mechanical and electrical compatibility: both share identical electrical specs (60 V, 2 A, 0.65 V VF), but B260BE-13 uses SMB package (larger than SMA), requiring PCB footprint revision. Thermal resistance improves (RθJA 90 vs. 95°C/W), supporting higher ambient operation if layout accommodates SMB dimensions.
