BSZ019N03LS Description

Short technical summary and product information.

The Infineon BSZ019N03LS is an N-channel OptiMOSTM Power MOSFET designed for high-performance applications such as server and VGA buck converters. It features a drain-source voltage (VDS) of 30V and a very low on-resistance (RDS(on)) of 1.9 mΩ at a gate-source voltage (VGS) of 4.5V.

This MOSFET offers excellent gate charge x RDS(on) product (FOM) for high-frequency switch-mode power supplies (SMPS). It boasts a continuous drain current (ID) of up to 149A at 25°C with VGS=10V and is 100% avalanche tested. The component is housed in a TSDSON-8 FL package suitable for surface mounting.

Key electrical characteristics include a typical gate charge of 44 nC and an output charge of 25 nC. The device is Pb-free, RoHS compliant, and halogen-free according to IEC61249-2-21 standards, making it suitable for environmentally conscious designs.
