Notes:
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.
Functional Diagram
• Fast response time:
typically less than 1.0ps
from 0 Volts to VBR min
• Typical IR less than 1μA
when VBR min>12V
• High temperature

guaranteed: 260°C/40sec
• VBR @ TJ= [email protected]°C
x (1+αT x (TJ - 25))
(αT:Temperature
Coefficient, typical value
is 0.1%)
• Plastic package is
flammability rated
V-0 per Underwriters
Laboratories
• Meet MSL level1, per
J-STD-020, LF maximun
peak of 260°C
• Matte tin lead–free plated
• Halogen free and RoHS
compliant
• Pb-free E3 means 2nd
level interconnect is
Pb-free and the terminal
finish material is tin(Sn)
(IPC/JEDEC J-STD609A.01)
Applications
TVS devices are ideal for the protection of I/O Interfaces,
VCC bus and other vulnerable circuits used in Telecom,
Computer, Industrial and Consumer electronic
applications.
