Electrical Characteristics (@ TA= 25 °C Unless Otherwise Noted)
Notes:
1. See Peak Pulse Power vs. Pulse Time.
Notes:
1. Test from individual pins 1, 2, 3, 4, 5 and 8 to ground pins 6 and 7 (unidirectional only).
2. Pins 6 & 7 not connected for bidirectional use.
The CDNBS08-SMDA05-6 series provides ESD, EFT and Surge
protection for external ports meeting IEC 61000-4-2 (ESD), IEC 61000-4-4
(EFT) and IEC 61000-4-5 (Surge) requirements.
The Transient Voltage Suppressor offers a Working Peak Reverse
Voltage from 5 V and Minimum Breakdown Voltage range of 6 V. The
device can protect 6 unidirectional Lines or 5 bidirectional lines which is
available in a JEDEC SO-8 package and intended to be mounted
directly onto an FR4 printed circuit board.
