B350B-E3/52T

Overview

The B350B-E3/52T is a single Schottky barrier rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes silicon technology and is housed in the SMB (DO-214AA) surface-mount package. The device supports an average forward current of 3 A with a repetitive peak reverse voltage of 50 V. Key electrical parameters include a maximum forward voltage of 660 mV at 3 A, a reverse leakage current of 100 µA, and a forward surge current capability of 60 A. It operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Schottky barrier construction for low forward voltage drop and high switching efficiency
• Silicon planar design utilizing metal-to-semiconductor contact
• Molded plastic case compliant with RoHS standards

Applications

• DC-DC converters
• Free-wheeling diodes
• Polarity protection circuits
• Power supply output rectification

Procurement Notes

Verify the specific suffix against official datasheets to confirm packaging format, as variations exist between tape-and-reel and cut-tape configurations. Ensure the component meets required environmental certifications such as RoHS and REACH for the target market. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a 50 V rating and 3 A continuous current are required in a compact SMB package. Consider the 660 mV forward voltage for thermal management in low-voltage applications. Verify that the 60 A surge current rating aligns with the circuit's inrush requirements. Compare performance against standard PN junction rectifiers where lower reverse recovery charge is necessary.

Part Context

This component belongs to the B350 series of Schottky rectifiers from Vishay. The series offers various voltage ratings and package options to suit different power density needs. The B350B variant specifically targets 50 V applications, providing a balance between current handling and voltage blocking capabilities in surface-mount designs.

Replacement Considerations

Direct substitutes must match the 50 V, 3 A, SMB package specifications. Check equivalent parts from other manufacturers for identical pinout and thermal characteristics.
