Overview
The B350B-E3/5BT is a silicon Schottky rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features an average forward current of 3 A and a maximum repetitive reverse voltage of 50 V. The device is housed in a surface-mount SMB (DO-214AA) package. Key electrical parameters include a maximum forward voltage of 660 mV, a peak forward surge current of 60 A, and a maximum reverse current of 100 uA. It operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- Utilizes silicon Schottky barrier technology for low forward voltage drop and high efficiency.
- Designed for surface mount assembly using the standard SMB (DO-214AA) leadless package.
- Capable of withstanding high transient surge currents up to 60 A.
Applications
- General purpose rectification in power supply circuits
- Freewheeling diodes in DC-DC converters
- Protection against polarity reversal in electronic systems
Procurement Notes
Verify the specific suffix 'E3' confirms compliance with RoHS directives and absence of halogenated flame retardants as per Vishay standards. Confirm the '5BT' designation corresponds to the correct tape and reel packaging configuration required for automated SMD placement processes. Ensure the component matches the DO-214AA footprint dimensions during PCB layout validation.
Selection Notes
Select this component when a 50 V blocking capability and 3 A continuous current rating are required in a compact surface-mount form factor. The low forward voltage characteristic makes it suitable for applications prioritizing energy efficiency. Consider the thermal management requirements associated with the SMB package size and the specified maximum junction temperature limit.
Part Context
This part belongs to the B350 series of Schottky rectifiers from Vishay. The series offers various voltage ratings and package options. The B350B specifically denotes the 50 V variant. The E3 suffix indicates environmental compliance, while the 5BT suffix typically refers to the specific reel quantity and packaging style used for manufacturing integration.
Replacement Considerations
Direct replacements must match the 50 V reverse voltage, 3 A forward current, and SMB (DO-214AA) package. Verify that alternative Schottky diodes maintain comparable forward voltage and reverse leakage characteristics to ensure circuit performance parity.
