Protection portfolio offers three new miniature, high-performance TVS diode families

Nexperia offers 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 1mm x 0.6mm of PCB space and with a height of 0.5mm, the new PTVS4V5D1BL TVS diode delivers excellent clamping characteristics and a typical surge robustness of 38.3A (8/20µA 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 5V to 26V (VRWM). These tiny devices measure just 1.6mm x 0.8mm and are 0.29mm high. 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 parts handle surge ratings up to 100A (8/20µA pulse). They also have an ultra-low dynamic resistance of 0.06ohm. Devices provide surge protection in charger ports, battery connectors and hard disks/SSDs. Three new 20V, 22V and 24V parts complete PTVSxU1UPA TVS family which now comprises nine diodes covering 7.5V to 26V. Devices come in the DFN2020-3 (SOT1061) package which has a footprint of 2mm x 2mm and a profile of just 0.62mm. Surge rating is up to a maximum of 178A for a 8/20µA pulse; peak pulse power is up to 300W for 10/1000µs pulse and leakage current is down to 1nA. The new parts target USB-PD applications. Comments Henning Riedel, product manager Protection, Nexperia: “We are already the leading supplier of ESD protection diodes and with these new introductions in small, leadless packages we have strengthened our TVS portfolio to suit emerging mobile applications such as USB PD.”
