Product details
Overview
B260AQ-13-F from Diodes Incorporated is a 60 V, 2.0 A surface-mount Schottky barrier rectifier in SMA package, featuring 0.70 V max forward voltage at 2.0 A and 0.5 mA max reverse leakage at rated VR and +25°C, optimized for low-voltage, high-frequency DC/DC conversion and freewheeling in automotive power supplies.
For engineers reviewing the B260AQ-13-F datasheet, B260AQ-13-F pinout, B260AQ-13-F application, or B260AQ-13-F equivalent, key selection criteria include its AEC-Q101 qualification, 50 A non-repetitive surge rating, RoHS-compliant lead-free finish, and thermal resistance of 25 °C/W (junction-to-lead), critical for thermally constrained PCB layouts.
Technical Context
This Schottky rectifier uses guard ring die construction to enhance transient immunity and suppress avalanche-induced failure during inductive switching events. Its low VF and fast recovery enable high-efficiency operation in 100 kHz–1 MHz switching converters without snubber networks.
Designed for automotive-grade reliability, it operates across –65°C to +150°C with validated thermal performance on FR-4 substrates (0.4" × 0.5", 2 oz Cu), and supports automated SMT assembly via matte tin-plated terminals compliant with MIL-STD-202, Method 208.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in 48 V automotive systems with 2× transient margin. |
| IO | 2.0 A - Average rectified output current; supports continuous conduction mode in 12 V/24 V buck converters up to ~30 W. |
| VF Max | 0.70 V @ 2.0 A - Low forward drop reduces conduction loss by >40% vs. standard PN diodes, improving efficiency in high-current paths. |
| IR Max | 0.5 mA @ 60 V, +25°C - Low leakage preserves battery standby time in always-on vehicle modules. |
| IFSM | 50 A - Peak surge rating handles motor startup transients and load dump events without degradation. |
| RθJL | 25 °C/W - Junction-to-lead thermal resistance enables direct heat sinking through cathode pad, simplifying thermal design. |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case with UL 94V-0 flammability rating, cathode indicated by band marking. Weight: 0.064 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current terminal | Connected to source side (e.g., switch node or input rail); must be routed with low-inductance trace for EMI control. |
| Cathode | Output current terminal | Connected to output rail or ground return; serves as primary thermal path-requires ≥25 mm² copper pour for RθJL optimization. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge breakdown under voltage transients, enabling robust operation in noisy automotive environments without external clamping. |
| AEC-Q101 qualification | Validated for automotive powertrain and body electronics per stress test requirements including HTGB, TCT, and HTRB. |
| Lead-free, halogen-free "Green" finish | Meets EU RoHS 3 (2015/863/EU) and JEDEC J-STD-020 moisture sensitivity Level 1-no bake required before reflow. |
| Surge rating: 50 A IFSM | Withstands 8.3 ms half-sine surges typical of solenoid de-energization and alternator load dump without parameter shift. |
Applications
| Automotive Body Control Module (BCM) | Industrial DC/DC Converter |
|---|---|
Use Scenario: Reverse polarity protection on 12 V supply input to microcontroller-based lighting control unit. IC Role / Device Role / Timing Role: Polarity protection diode placed upstream of LDO regulator and CAN transceiver. Use Value: Prevents damage from accidental battery reversal while adding <0.7 V dropout-preserving headroom for 3.3 V logic rails. | Use Scenario: Freewheeling path in synchronous buck converter powering FPGA I/O banks. IC Role / Device Role / Timing Role: Freewheel diode in non-synchronous configuration during low-duty-cycle operation. Use Value: Enables zero-cross detection timing stability by eliminating reverse recovery tail, reducing output ripple by 15% vs. fast recovery diode. |
| USB-C Power Delivery Adapter | Telecom PoE Midspan Injector |
Use Scenario: Output rectification in 20 V/3 A flyback secondary stage. IC Role / Device Role / Timing Role: Secondary-side Schottky rectifier replacing synchronous MOSFET for cost-sensitive designs. Use Value: Delivers 89% efficiency at full load with no gate drive complexity-reducing BOM count by one IC and two passives. | Use Scenario: Blocking diode in 48 V DC feed path to powered device interface. IC Role / Device Role / Timing Role: Blocking diode isolating midspan PSE from legacy PD equipment during hot-swap insertion. Use Value: Limits fault current propagation with <0.5 mA leakage at 57 V-ensuring IEEE 802.3af/at compliance during cable fault conditions. |
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 | Same 60 V/2 A rating but SMB package (RθJA = 80 °C/W vs. SMA's 25 °C/W); VF = 0.75 V @ 2 A. | Higher thermal resistance limits use in high-ambient industrial enclosures (>85°C) without forced airflow. | Select when board space allows larger SMB footprint and lower-cost packaging is prioritized over thermal performance. |
| SS26HE3_A/H | 60 V/2 A, VF = 0.72 V @ 2 A, but not AEC-Q101 qualified; RθJL = 28 °C/W. | Not approved for automotive under-hood use; leakage rises to 1.2 mA at +100°C vs. B260AQ-13-F's 20 mA spec. | Select for consumer-grade AC/DC adapters where automotive qualification and elevated temperature leakage are non-critical. |
Compared with SB260-E3/52 and SS26HE3_A/H, B260AQ-13-F delivers superior thermal management in compact layouts and guaranteed automotive reliability-making it the preferred choice for space-constrained, high-temperature, and safety-critical applications.

FAQ
What is the maximum junction temperature for continuous operation?
The B260AQ-13-F has an operating junction temperature range of –65°C to +150°C. For continuous 2.0 A operation, thermal design must ensure TJ remains ≤150°C-achievable with ≥25 mm² copper on cathode pad and ambient ≤85°C, per Fig. 4 derating curve.
Is this diode suitable for synchronous rectification replacement?
No-B260AQ-13-F is a passive Schottky rectifier, not a synchronous rectifier controller or MOSFET driver. It replaces standard diodes in non-synchronous topologies; for synchronous designs, a dedicated gate driver IC and low-RDS(on) MOSFET are required.
Does the "-13-F" suffix indicate tape-and-reel packaging?
Yes-the "-13-F" suffix denotes 5,000-piece tape-and-reel packaging in 8 mm carrier tape, compatible with standard SMT pick-and-place equipment. The "F" confirms lead-free, RoHS-compliant plating per Diodes Incorporated specification.
How does its leakage current compare at elevated temperatures?
At +100°C and rated 60 V reverse bias, IR is specified ≤20 mA-significantly higher than the 0.5 mA at +25°C. This increase is inherent to Schottky physics and must be accounted for in battery-powered standby circuits where microamp-level leakage is critical.
