Targets interfaces with high surge protection requirements including USB Power Delivery in portable devices
Nijmegen: Nexperia announced three miniature TVS diode families that are available in space-saving packages for applications in portable devices, including USB – Power Delivery (USB-PD) protection. All the new parts feature high surge ratings and high peak pulse power.
Taking up just 1 x 0.6 mm (DFN1006-2/SOD882 package) of PCB space and with a height of 0.5 mm, the new PTVS4V5D1BL TVS diode delivers very good clamping characteristics and a typical surge robustness of 38.3 A (8/20 µA pulse), which is industry benchmark for a device of this size and specification. Applications include battery line and audio port protection.
The new PTVSxZ1USK series includes 10 new types within a reverse standoff voltage range from 5 V to 26 V (VRWM). These tiny devices measure just 1.6 x 0.8 mm and are 0.29 mm high (DSN1608-2 / SOD964 package). This is a significant reduction of package height compared to devices currently available in this performance class which are usually 0.5 mm high. The new Nexperia parts handle surge ratings up to 100 A (8/20 µA pulse). They also have an ultra-low dynamic resistance of 0.06Ω. Devices provide surge protection in charger ports, battery connectors and hard disks/SSDs.
Three new 20 V, 22 V and 24 V parts complete Nexperia’s PTVSxU1UPATVS family which now comprises nine diodes covering 7.5 V to 26 V. Devices come in the DFN2020-3 (SOT1061) package which has a footprint of 2 x 2 mm and a profile of just 0.62 mm. Surge rating is up to a maximum of 178 A for a 8/20 µA pulse; peak pulse power is up to 300 W for 10/1000 µs pulse and leakage current is down to 1 nA. The new parts target USB-PD applications.
