• For surface mounted
applications to optimize
board space
• VBR @TJ= VBR@25°C
x (1+αT x (TJ - 25))
(αT:Temperature
Coefficient, typical value
is 0.1%)
• Plastic package is
flammability rated V-0 per

Notes:
Applications
1. Non-repetitive current pulse, per Fig.4 and derated above TJ (initial) =25ºC per Fig. 3.
2. Mounted on 5.0x5.0mm copper pad to each terminal.
3. Measured on 8.3ms single half sine wave or equivalent square wave for unidirectional device only.
4. VF < 3.5V for single die parts and VF< 5.0V for stacked-die parts.
5. 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 inTelecom,
V
Computer, Industrial and Consumer electronic applications.
