Product details
Overview
B260AF-13 from Diodes Incorporated is a 60 V, 2 A surface-mount Schottky barrier rectifier in SMAF package, featuring 0.65 V max forward voltage at 2 A and 0.20 mA max reverse leakage at 60 V / +25°C, optimized for high-efficiency DC/DC boost stages and recirculating paths in power supplies.
For engineers reviewing the B260AF-13 datasheet, B260AF-13 pinout, B260AF-13 application, or B260AF-13 equivalent, key selection criteria include its low VF at high temperature, stable IR up to +125°C, thermal resistance (RθJA = 95°C/W), junction capacitance (80 pF), and RoHS-compliant green molding compound.
Technical Context
This Schottky rectifier uses a planar metal-silicon junction structure enabling low forward conduction loss and minimal minority-carrier storage, eliminating reverse recovery time. Its 60 V VRRM rating supports use in 48 V input systems with margin, while the 50 A non-repetitive surge rating accommodates inrush and transient events.
The device operates across –55°C to +150°C, with reverse leakage tightly controlled (0.20 mA @ +25°C, 15 mA @ +125°C) and VF maintained at 0.52 V typical at 2 A / +125°C - critical for thermally constrained PCB layouts and high ambient environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Withstands repetitive reverse voltage up to 60 V, suitable for 48 V bus applications with safety margin |
| IO(AV) | 2 A - Continuous DC output current capability under defined thermal conditions (FR-4, 0.4"×0.5") |
| VF(max) | 0.65 V @ 2 A, +25°C - Enables <1.3 W conduction loss per diode in high-current paths |
| IR(max) | 0.20 mA @ 60 V, +25°C - Low leakage preserves efficiency in blocking mode; rises to 15 mA @ +125°C |
| RθJA | 95 °C/W - Junction-to-ambient thermal resistance on standard FR-4 board, informs heatsinking requirements |
| CT | 80 pF @ 4 V, 1 MHz - Low junction capacitance minimizes switching noise and EMI in high-frequency converters |
Pinout & Package
Package: SMAF (Surface-Mount Axial Flat), molded plastic case with matte tin–annealed copper leadframe; cathode indicated by band; UL 94V-0 rated; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry terminal | Connected to lower-potential node (e.g., switch node in boost converter); requires low-inductance layout |
| Cathode | Forward current exit / reverse-blocking terminal | Connected to output rail or ground return; marked by visible band; carries full load current |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | 0.65 V max @ 2 A ensures <1.3 W conduction loss, reducing thermal stress in compact power stages |
| High-temperature reverse leakage stability | 0.20 mA @ +25°C and 15 mA @ +125°C enables reliable operation in sealed or high-ambient enclosures |
| Lead-free and halogen-free construction | Meets RoHS 2 (2011/65/EU) and "Green" definition (<900 ppm Br/Cl, <1000 ppm Sb), supporting environmental compliance programs |
| Optimized thermal resistance | RθJC = 45°C/W allows efficient heat transfer to PCB copper pads, improving power density in space-constrained designs |
Applications
| Boost Diode | Blocking Diode |
|---|---|
Use Scenario: Used in non-isolated boost converters to transfer energy from input to output during switch-off phase. IC Role / Device Role / Timing Role: Unidirectional current path enabling inductor energy transfer; conducts only when MOSFET is off. Use Value: Low VF minimizes power loss during conduction; low CT reduces high-frequency ringing and EMI generation. | Use Scenario: Placed between parallel power sources (e.g., battery and USB input) to prevent backflow. IC Role / Device Role / Timing Role: Reverse-biased isolation element blocking reverse current during source switchover. Use Value: Stable IR at elevated temperature prevents thermal runaway and ensures long-term reliability in always-on systems. |
| Recirculating Diode | OR-ing Diode |
Use Scenario: Provides freewheeling path for inductive loads (e.g., solenoids, relays) after driver turn-off. IC Role / Device Role / Timing Role: Clamps inductive kickback voltage and dissipates stored magnetic energy. Use Value: Fast zero-recovery behavior eliminates switching delay and voltage overshoot; 50 A IFSM handles peak flyback surges. | Use Scenario: Enables redundant power supply inputs (e.g., dual DC inputs) with automatic source selection. IC Role / Device Role / Timing Role: Forward-biased conduction path for active source; reverse-biased isolation for inactive source. Use Value: Low VF reduces insertion loss and voltage drop across each path, preserving system efficiency and regulation accuracy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB260-E3/54 (Vishay) | Same 60 V VRRM, 2 A IO, but VF = 0.75 V max @ 2 A; RθJA = 100°C/W | Higher conduction loss and thermal resistance reduce efficiency in thermally dense layouts | Prefer B260AF-13 where board space or ambient temperature limits thermal headroom |
| SS26 (ON Semiconductor) | 60 V VRRM, 2 A IO, VF = 0.72 V max @ 2 A; IR = 0.5 mA @ 60 V / +25°C | Higher leakage may compromise blocking performance in high-temp backup systems | Prefer B260AF-13 for applications requiring <0.2 mA leakage at room temperature |
Compared with SB260-E3/54 and SS26, B260AF-13 delivers lower forward voltage and tighter reverse leakage control - directly translating to reduced conduction loss and improved thermal stability in 48 V industrial and telecom power stages.

FAQ
What is the maximum operating temperature for B260AF-13?
The B260AF-13 is rated for continuous operation from –55°C to +150°C junction temperature. Its reverse leakage remains within specification (≤15 mA) at +125°C, and thermal resistance values (RθJA = 95°C/W, RθJC = 45°C/W) are measured under JEDEC-standard FR-4 board conditions.
Is B260AF-13 compatible with lead-free reflow soldering processes?
Yes - B260AF-13 features a matte tin–annealed copper leadframe and is qualified for lead-free reflow per J-STD-020, with moisture sensitivity level 1. Its UL 94V-0 green molding compound withstands peak reflow temperatures up to 260°C without delamination or degradation.
Does B260AF-13 have a specified reverse recovery time (trr)?
No - as a Schottky barrier rectifier, B260AF-13 has no minority-carrier storage and therefore exhibits effectively zero reverse recovery time. This eliminates switching losses and associated EMI seen in PN-junction rectifiers, confirmed by absence of trr parameter in DS39508.
How does the SMAF package differ from standard SMA?
The SMAF package is a flattened variant of SMA with reduced height (max 1.10 mm vs. SMA's ~2.3 mm) and optimized pad layout (0.2" × 0.25" copper area). It provides identical electrical performance but enables thinner assemblies and improved thermal coupling to PCB copper due to shorter internal leads and flatter profile.
