TVS Diodes offer High Surge Robustness

November 01, 2015 by Jeff Shepard

NXP Semiconductors has announced the first products in a new series of transient voltage suppressor (TVS) diodes, housed in a small, leadless package DSN1608-2 (1.6 x 0.8 mm) with a height of only 0.26 mm. The new PTVSxZ1USK(N) product series offers a high surge rating of up to 80 A (8/20 µs pulse for 5 V type) and 200 W peak pulse power rating (10/1000 µs) respectively. Reverse stand-off voltages are 5 V and 12 V. The complete series will include 16 types ranging from 5 to 26 V.

Designed for supply lines protection in all space constrained and thin applications including smart phones, solid-state or hard-disk drives, and other mobile devices. Key specifications for the 5V PTVS5V0Z1USKN include: Reverse standoff voltage, VRWM = 5 V; Rated peak pulse current, IPPM = 80A (8/20 µs pulse); and Rated peak pulse power, PPPM = 200W (10/1000 µs pulse). Key specifications for the 12V PTVS12VZ1USKN include: Reverse standoff voltage, VRWM = 12 V; Rated peak pulse current, IPPM = 59A (8/20 µs pulse); and Rated peak pulse power, PPPM = 200W (10/1000 µs pulse).

Surge pulses, which are generated by grid instabilities and lightning transients, are a threat to any product connected to a power source e.g. supply line or a charging port. While surge pulses are longer pulses of a lower voltage than ESD, they still contain more electric energy and can destroy unprotected electronic circuits. These TVS diodes have high surge ratings and can provide protection for smart phones and other mobile devices that need to be charged regularly.
