STMicroelectronics, Inc. Solid State Relays - PCB Mount VNI4140KTR-32

The VNI4140KTR-32 is a quad high-side smart power solid-state relay in a PowerSSO-24 package, designed to drive four independent resistive, capacitive, or inductive loads with 1 A per channel and a maximum voltage of 41 V. It features built-in protections including shorted load, overtemperature, and undervoltage shutdown, with non-simultaneous restart of overloaded channels to prevent supply current spikes. The device includes open-drain diagnostic outputs and 3.3 V CMOS/TTL compatible inputs. It conforms to IEC 61131-2 and offers ESD protection up to ±25 kV per IEC 61000-4-2. The part is supplied in tape and reel packaging.
