Diodes Incorporated SBR2U10LP-13

Overview

SBR2U10LP-13 from Diodes Incorporated is a 10 V, 2 A surface-mount Super Barrier Rectifier (SBR®) in X1-DFN1411-3 package, featuring ultra-low 0.46 V max forward voltage at 2 A and 2 mA max reverse leakage at 10 V/25°C. It serves as a freewheeling, bypass, or polarity protection diode in solar panel interfaces and portable electronics power rails.

For engineers reviewing the SBR2U10LP-13 datasheet, SBR2U10LP-13 pinout, SBR2U10LP-13 application, or SBR2U10LP-13 equivalent, key selection criteria include low VF conduction loss, high-temperature IR stability up to 150°C, compact DFN footprint, and RoHS-compliant lead-free construction.

Technical Context

The SBR2U10LP-13 uses a proprietary Super Barrier Rectifier structure that achieves lower VF than Schottky diodes while maintaining superior thermal stability of reverse leakage. Its junction capacitance is 102 pF at 5 V, and trr is rated 43–60 ns under defined test conditions.

Designed for operation across –65°C to +150°C, it delivers 2 A average rectified current with 21 A non-repetitive surge capability and thermal resistance RθJA = 210°C/W on FR-4 PCB. Anode pins (1 & 2) must be electrically joined on PCB for optimal performance per datasheet Note 7.

FAQ

Is SBR2U10LP-13 pin-compatible with standard Schottky diodes in DFN packages?

No. While it shares the X1-DFN1411-3 footprint, SBR2U10LP-13 has dual-anode terminals (Pins 1 & 2) that must be shorted on the PCB per datasheet Note 7. Standard Schottky DFNs typically use single-anode configurations, so layout revision is required to ensure both anode pads are connected.

What is the maximum continuous current at 100°C ambient temperature?

Per Figure 5, the average rectified forward current derates to approximately 1.45 A at 100°C ambient with no heatsink. This value assumes mounting on a 1" × 1", 2 oz copper FR-4 board per Note 6. Adding a small copper pour can extend usable current to ~1.65 A at 100°C.

Does SBR2U10LP-13 require special reflow profile considerations?

Yes. As a moisture-sensitivity level 1 device, it does not require baking prior to reflow. However, its thin DFN package (0.5 mm height) and NiPdAu-plated terminals demand precise peak temperature control: maximum 260°C for ≤30 seconds, with ramp rates per J-STD-020 Class 2 guidelines to avoid delamination or voiding.

Can SBR2U10LP-13 replace a 1N5819 in existing designs?

Only with layout modification. The 1N5819 is axial-lead (DO-41) with 1 A rating and 0.475 V VF. SBR2U10LP-13 offers 2× current capacity and similar VF but requires DFN footprint adaptation, dual-anode routing, and verification of thermal performance on the target PCB stack-up.
