VN340SP-33-E ST Power Switch | 10-PowerSO | 36V, 4-Channel

Product Overview

The VN340SP-33-E is a monolithic quad high-side smart power switch manufactured by STMicroelectronics, featuring four independent 0.5Ω (typical) N-channel power MOSFETs with embedded protection and diagnostic functions. Housed in a compact 10-PowerSO package, it is designed for driving resistive, inductive, and capacitive loads in harsh automotive and industrial environments. The device operates from a 36V maximum supply voltage and integrates advanced protection features including overcurrent, overtemperature, and short-circuit protection, as well as a dedicated diagnostic output for fault reporting.
