Fuel and injection control units must fire injector solenoids or piezo elements with microsecond precision and repeatable current profiles, cycle after cycle, to keep combustion efficient and emissions in check.

Vishay's power MOSFETs and diodes / rectifiers switch injector drive currents cleanly and our power modules with integrated freewheeling diodes eliminate layout parasitic inductance and provide safe energy dissipation when injector solenoid current ceases. Precision current sensing resistors and film capacitors ensure accurate, repeatable timing, and resistor networks and NTC thermistors provide signal conditioning and temperature compensation needed for consistent performance.

Behind fuel injection reliability and efficiency is The DNA of tech.®
