Power Integrations announced that its 200 V Qspeed diodes – LQ10N200CQ and LQ20N200CQ – are now available with AEC-Q101 automotive qualification. Qspeed silicon diodes use merged-PIN technology to offer a unique balance of soft switching and low reverse recovery charge (Qrr). This results in low EMI and reduced output noise, which is especially important for […]

Advanced circuit protection for connected autonomous vehicles
New protocols for high connectivity need robust protection for reliability and safety. James Colby | Littelfuse, Inc. At the turn of the century, automobiles hosted many electronic systems that were basically independent. Since then, the growth of connectivity and the rise of artificial intelligence and machine learning have changed automotive electronics dramatically. Vehicles of all […]
Varistors ARE viable for surge protection
by Patrik Kalbermatten, KEMET Protecting sensitive electronic equipment against transient voltages in the form of surges that may be either circuit emanating from relays or motors, or significant ESD events such as lightning strikes, is a vital part of equipment design. Several technologies exist to protect sensitive electronic circuitry from voltage surges, including gas discharge […]
