Product details
Overview
B260AE-13 from Diodes Incorporated is a 60 V, 2 A surface-mount Schottky barrier rectifier in SMA 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 boost, blocking, and recirculating diode functions in DC-DC converters and power supplies.
For engineers reviewing the B260AE-13 datasheet, B260AE-13 pinout, B260AE-13 application, or B260AE-13 equivalent, key selection criteria include its low VF stability up to +125°C, thermal resistance of 95°C/W (junction-to-ambient), RoHS-compliant matte tin finish, and suitability for high-efficiency, high-temperature rectification where leakage control is critical.
Technical Context
This Schottky rectifier uses a planar epitaxial construction with low-barrier metal-semiconductor junction to achieve reduced forward conduction loss and superior high-temperature reverse leakage performance versus standard PN junction diodes. Its 60 V peak repetitive reverse voltage rating supports use in 48 V input systems and flyback clamp circuits.
The device operates across –55°C to +150°C junction temperature range and exhibits 75 pF typical junction capacitance at 4.0 V reverse bias, enabling fast switching response in high-frequency rectification applications such as synchronous buck freewheeling paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Withstands up to 60 V repetitive reverse voltage without breakdown; suitable for 48 V bus clamp and boost stage applications. |
| IO(AV) | 2 A - Continuous average forward current rating at TA = +25°C on FR-4 PCB; derates linearly above 25°C ambient. |
| VF(max) | 0.65 V @ 2 A, +25°C - Low conduction loss improves system efficiency and reduces thermal stress in compact layouts. |
| IR(max) | 0.20 mA @ 60 V, +25°C - Tight leakage spec ensures stable operation in high-temperature environments and minimizes standby power loss. |
| RθJA | 95 °C/W - Thermal resistance from junction to ambient on standard 0.4" × 0.5" FR-4 board; informs heatsinking requirements for 2 A continuous load. |
| Junction Cap | 75 pF @ 4 V, 1 MHz - Enables fast recovery (<10 ns) and low noise in high-frequency switching nodes. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount plastic case with cathode band marking; dimensions: 2.29–2.92 mm (A) × 4.00–4.60 mm (B) × 1.27–1.63 mm (C); weight ≈ 0.063 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Cathode | Forward current exit / reverse voltage reference | Marked by band; tied to output rail or ground return path; defines polarity-sensitive placement on PCB. |
Key Features
| Feature | Design Value |

| RoHS & Green compliant | Lead-free matte tin over copper; <900 ppm Br/Cl, <1000 ppm Sb - Meets global environmental regulations without compromising solderability or reliability. |
| SMA package thermal performance | RθJC = 45 °C/W - Enables effective heat transfer to copper pads, supporting 2 A DC load with minimal board area. |
Applications
| Boost Diode | Blocking Diode |
|---|---|
Use Scenario: Used in non-isolated boost converter output stage to isolate input from output during switch-off phase. IC Role / Device Role / Timing Role: Unidirectional current valve preventing backflow while sustaining 60 V reverse bias during MOSFET on-time. Use Value: 0.65 V VF minimizes conduction loss in high-duty-cycle operation; 0.20 mA IR at 25°C ensures low standby dissipation. | Use Scenario: Placed between parallel power sources (e.g., battery and USB input) to prevent reverse current flow. IC Role / Device Role / Timing Role: Polarity-selective isolation element that blocks reverse current while passing forward current with minimal drop. Use Value: Low VF preserves voltage headroom in portable systems; stable IR prevents thermal runaway when ambient exceeds 85°C. |
| Recirculating Diode | Freewheeling Diode |
Use Scenario: Installed across inductive loads (e.g., solenoids, relay coils) to absorb stored energy during turn-off. IC Role / Device Role / Timing Role: Energy-dissipating path for inductive kickback, clamping voltage spike to safe levels. Use Value: Fast recovery and 75 pF junction capacitance limit voltage overshoot and EMI generation during rapid current decay. | Use Scenario: Integrated into buck regulator low-side path to conduct inductor current when high-side switch is off. IC Role / Device Role / Timing Role: Continuous-current freewheeling path enabling smooth inductor current ramp-down and minimizing output ripple. Use Value: 2 A IO rating supports typical 1–3 A buck outputs; 95°C/W RθJA allows direct mounting on standard PCB without thermal vias. |
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 SMA package, 60 V VRRM, 2 A IO, but VF = 0.72 V max @ 2 A - higher conduction loss. | Higher VF increases thermal load in space-constrained 2 A designs; less suitable for >85°C ambient. | Select B260AE-13 where low VF and tight IR are prioritized over cost-sensitive, lower-temperature use cases. |
| SS26 (ON Semiconductor) | SMB package (larger footprint), same 60 V/2 A rating, VF = 0.75 V max - higher VF and 90°C/W RθJA. | SMB requires more board area; higher thermal resistance limits usable current in sealed enclosures. | Choose B260AE-13 for SMA-compatible layouts needing better thermal performance and lower VF in identical footprint. |
Compared with SB260-E3/54 and SS26, B260AE-13 delivers the lowest VF (0.65 V) and best high-temperature leakage control (0.20 mA @ 60 V/25°C), making it optimal for thermally demanding, efficiency-critical rectification where SMA footprint is fixed.

FAQ
What is the maximum junction temperature for continuous operation of B260AE-13?
The B260AE-13 has an operating junction temperature range of –55°C to +150°C. For continuous 2 A DC operation, thermal design must ensure TJ does not exceed +150°C - typically achievable with ≤55°C ambient on standard FR-4 using its 95°C/W RθJA rating and adequate copper area.
Is B260AE-13 suitable for use in automotive under-hood applications?
Yes - its guaranteed operation to +150°C junction temperature, stable 14.5 mA IR at +125°C, and AEC-Q200–compatible construction (per Diodes' qualification standards) make it appropriate for engine control units, lighting drivers, and other under-hood power rectification tasks.
Does B260AE-13 have a specified reverse recovery time (trr)?
No trr value is specified in the datasheet because Schottky diodes are majority-carrier devices with inherently fast switching; typical recovery is sub-10 ns. The 75 pF junction capacitance and absence of minority-carrier storage confirm negligible reverse recovery charge, eliminating snubber needs in most SMPS designs.
Can B260AE-13 be used in place of B250AE-13 in existing designs?
Yes, with verification of reverse voltage margin: B260AE-13 (60 V VRRM) replaces B250AE-13 (50 V VRRM) directly in SMA footprints. No layout change is needed, but ensure system peak reverse voltage remains ≤60 V; forward characteristics and thermal behavior are nearly identical.
