Nexperia, the former Standard Products division of NXP, today announced a new generation of in-vehicle network (IVN) protection diodes that offer a higher surge current, greater ESD robustness and a significant improvement in ESD clamping performance. The new AEC-Q101 qualified PESDxIVN series of surface mount devices is optimized for the latest generation of CAN, LIN, and FlexRay transceivers.
The new parts are drop-in replacement for legacy devices, available in familiar SOT23, SOD323 and SOT323 packages. However the new parts deliver higher performance. For example, PESD2IVN24-T parts deliver a 30 kV ESD robustness (up from 23 kV on the legacy PESD1CAN), an improved surge current of 3.5 A and much better clamping of 42 V at 3.5 A (was 70 V at 3 A). Other parameters remain constant or slightly better. The PESD1IVN27-A offers the same improvement in ESD robustness with a lower (=better) clamping voltage compared to the legacy PESD1LIN.
