Product details
Overview
B260A-13-F from Diodes Incorporated is a 2.0A surface-mount Schottky barrier rectifier in SMA package, rated for 60V peak repetitive reverse voltage (VRRM), 0.70V max forward voltage at 2.0A, and 50A non-repetitive surge current. It serves as a low-loss freewheeling or polarity protection diode in DC-DC converters and automotive power supplies.
For engineers reviewing the B260A-13-F datasheet, B260A-13-F pinout, B260A-13-F application, or B260A-13-F equivalent, key selection criteria include forward voltage drop at rated current, thermal resistance (25°C/W junction-to-lead), surge capability, RoHS/Green compliance, and AEC-Q101 qualification status for automotive use.
Technical Context
This Schottky rectifier uses guard ring die construction to enhance transient robustness and supports high-frequency switching up to several hundred kHz. Its low forward voltage minimizes conduction loss in low-voltage (≤12V) power rails, while its 50A IFSM rating enables reliable operation during load dump or inductive kick events.
The device operates across –65°C to +150°C and features a cathode band polarity indicator. Thermal resistance of 25°C/W (junction-to-lead) requires proper PCB copper pour for thermal management under sustained 2.0A load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum reverse blocking voltage before breakdown; defines usable input voltage range in buck/flyback outputs. |
| IF(AV) | 2.0 A - Continuous average forward current; sets minimum trace width and heatsinking requirements on PCB. |
| VF @ 2.0A | 0.70 V max - Forward voltage drop at rated current; determines conduction loss (1.4W max at 2A) and thermal rise. |
| IFSM | 50 A - Non-repetitive surge rating (8.3ms half-sine); supports inrush and fault-current handling without failure. |
| RθJL | 25 °C/W - Junction-to-lead thermal resistance; requires ≥100 mm² 2-oz copper pad for safe 2A operation at +125°C ambient. |
| IR @ VR | 0.5 mA max @ 60V, 25°C - Reverse leakage; impacts standby power in battery-backed systems. |
| CT @ 40V | 200 pF - Junction capacitance at 40V bias; limits high-frequency switching efficiency above ~1 MHz. |
Pinout & Package
SMA (DO-214AC) surface-mount package with molded plastic case (UL 94V-0), matte tin-plated terminals, and cathode band polarity marking. Weight: 0.064 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter); must route with low-inductance path. |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; connects to output rail or ground return; carries full load current and must be thermally anchored. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Improves ESD and transient immunity without external TVS, reducing BOM count in automotive ECUs. |
| AEC-Q101 qualified | Validated for automotive underhood applications including engine control and lighting modules. |
| Lead-free & Halogen-free | Meets RoHS 2 and JEDEC J-STD-020 Level 1 moisture sensitivity; compatible with standard reflow profiles. |
| High-temp solderability | Rated for 260°C/10s at terminals-supports lead-free assembly without delamination or bond lift. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB260-E3/52 (Vishay) | Same SMA package, 60V VRRM, but VF = 0.72V max @ 2A; RθJL = 28°C/W. | Higher VF increases conduction loss by ~3% at 2A; slightly lower thermal performance. | Select if Vishay sourcing is preferred and 0.02V VF increase is acceptable in thermal budget. |
| SS26 (ON Semiconductor) | SMB package (larger footprint), same 60V/2A rating, VF = 0.75V max @ 2A, RθJL = 20°C/W. | Larger SMB package improves thermal dissipation but consumes more board area. | Choose when board space allows and lower thermal resistance (20 vs. 25°C/W) is prioritized over compactness. |
Compared with SB260-E3/52 and SS26, B260A-13-F offers the lowest VF (0.70V) in SMA form factor and best balance of size, efficiency, and AEC-Q101 qualification-making it optimal for space-constrained automotive and industrial power stages.

FAQ
Is B260A-13-F AEC-Q101 qualified?
Yes. B260A-13-F is explicitly qualified to AEC-Q101 standards for high reliability, as confirmed in Diodes Incorporated's DS13004 Rev. 22 datasheet and ordering information table. This qualification covers temperature cycling, humidity testing, and mechanical stress validation required for automotive underhood applications.
What is the maximum junction temperature for continuous operation?
The absolute maximum junction temperature is +150°C, and the device is rated for continuous operation across –65°C to +150°C. At 2.0A average current and TA = +125°C, thermal design must ensure TJ remains ≤150°C-achievable with ≥100 mm² 2-oz copper pad per the datasheet's recommended layout.
Can B260A-13-F replace B240A-13-F in a design?
Yes, with voltage margin consideration. B260A-13-F has higher VRRM (60V vs. 40V) and identical IF(AV) (2.0A), VF (0.70V max), and package (SMA). It provides enhanced reverse voltage headroom in 24V or 36V systems where B240A may operate near its limit, improving long-term reliability.
Does B260A-13-F have a cathode notch or band marking?
It uses a cathode band marking, not a notch. The datasheet specifies "Cathode Band or Cathode Notch" as polarity indicators, and the B2xxA series-including B260A-13-F-is marked with a distinct cathode band on the body, visible in top-view illustrations and consistent with SMA industry convention.
