Overview
The B240A-E3/5AT is a Schottky rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a single diode configuration in an SMA (DO-214AC) surface-mount package. Key electrical parameters include a maximum repetitive reverse voltage of 40 V and an average forward rectified current of 2 A. The device exhibits a typical forward voltage of 550 mV at 2 A and a maximum reverse leakage current of 500 uA. It supports a forward surge current of 50 A and operates within a junction temperature range of -65°C to +150°C.
Feature Summary
- Utilizes silicon Schottky barrier technology for low forward voltage drop and high efficiency.
- Designed for surface mount installation in compact SMA (DO-214AC) packages.
- Capable of withstanding high thermal stress with a maximum junction temperature of 150°C.
Applications
- DC-DC converters
- Free-wheeling diodes in power supplies
- Polarity protection circuits
Procurement Notes
Verify the specific ordering suffix /5AT against the manufacturer's datasheet to confirm packaging details, as suffixes often denote tape-and-reel quantities or specific handling requirements. Ensure compliance with RoHS directives and REACH SVHC standards relevant to the production batch. Cross-reference the full part number with official Vishay documentation to validate availability and lead times before procurement.
Selection Notes
Select this component when a 40 V rating and 2 A continuous current capacity are required in a small surface-mount footprint. The low forward voltage characteristic makes it suitable for applications prioritizing energy efficiency. Compare performance metrics such as reverse leakage and thermal resistance against alternative Schottky diodes in the same package family to ensure optimal circuit design compatibility.
Part Context
This part belongs to the Vishay B2xxxA series of Schottky rectifiers, which are designed for general-purpose rectification in low-voltage, high-frequency applications. The series offers various current ratings and voltage options within standardized DO-214AC packages, providing designers with flexible solutions for space-constrained power management designs.
Replacement Considerations
Direct substitutes may include other Vishay Schottky diodes with identical 40 V and 2 A ratings in the SMA package, such as the B240A-E3/61T, provided pinout and electrical characteristics match exactly. Verify that any replacement maintains the same thermal and mechanical specifications.
