1. Non-repetitive current pulse , per Fig. 4 and derated above TJ (initial) =25OC per Fig. 3.
2. Mounted on copper pad area of 0.31x0.31” (8.0 x 8.0mm) to each terminal.
3. Measured on 8.3ms single half sine wave or equivalent square wave for unidirectional
component only, duty cycle=4 per minute maximum.
4. VF < 3.5V for single die parts and VF< 5.0V for stacked-die parts.
5. The PPPM of stacked-die parts is 4000W and please contact Littelfuse for stacked-die part
details.
TVS components are ideal for the protection of I/O
Interfaces, VCC bus and other vulnerable circuits used in
telecom, computer, Industrial and consumer electronic
applications.
