Overview
The SB2540DC is a Schottky diode array manufactured by SMC Diode Solutions. It features a maximum DC reverse voltage (Vr) of 40 V and an average forward current (Io) of 25 A. The device utilizes a D2PAK-3 surface-mount package, specifically TO-263-3 with a tab. Key electrical parameters include a maximum forward voltage (Vf) of 550 mV at 12.5 A and a low junction capacitance typical for Schottky technology. The component operates within a junction temperature range of -55°C to 150°C and is RoHS compliant.
Feature Summary
- Dual Schottky barrier rectifier configuration in a single surface-mount package
- Low forward voltage drop for improved power efficiency
- High thermal stability with extended operating temperature range
Applications
- DC-DC converter modules
- Power supply freewheeling circuits
- Polarity protection applications
Procurement Notes
Verify the specific suffix or tape-and-reel quantity against the manufacturer's latest datasheet before ordering. Confirm that the D2PAK footprint matches the target PCB design. Ensure compliance with REACH and RoHS directives as stated in the official documentation. Cross-reference the part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a dual Schottky configuration is required in a compact surface-mount form factor. The 40 V rating suits low-voltage DC systems. Evaluate the 25 A current capacity against peak load requirements. Consider the thermal performance of the D2PAK package for heat dissipation needs in dense circuit layouts.
Part Context
This part belongs to SMC Diode Solutions' Schottky rectifier family. It complements other low-voltage, high-current devices like the SB2540 series variants. The D2PAK packaging allows for automated assembly processes. It serves as a robust solution for modern power management designs requiring fast switching and low loss.
Replacement Considerations
Check for direct equivalents from other manufacturers offering identical 40 V, 25 A Schottky arrays in D2PAK packages. Verify pinout compatibility and thermal resistance values. Ensure Vf and leakage current specifications meet or exceed the original design requirements.
