Notes:
1. Non-repetitive current pulse , per Fig. 4 and derated above TJ (initial) =25OC per Fig. 3.
Applications
2. Measured on 8.3ms single half sine wave or equivalent square wave, duty cycle=4 per minute maximum.
3. VF < 3.5V for single die parts and VF< 5.0V for stacked-die parts.
4. For stacked die component details, please refer to part numbers labeled by * in Electrical Characteristics.
TVS devices are ideal for the protection of I/O interfaces,
CC bus and other vulnerable circuits used in telecom,
