Low profile package
Typical failure mode is short from over-specified voltage or current
Whisker test is conducted based on JEDEC JESD201A per its table 4a and 4c
ESD protection of data lines in accordance with IEC 61000-4- 2, 30kV(Air), 30kV (Contact)
EFT protection of data lines in accordance with IEC 61000- 4-4
Built-in strain relief
400W Peak pulse power capability at 10/1000μs waveform, repetition rate (duty cycle): 0.01%
Fast response time: typically less than 1.0ps from 0 Volts to V_BR min
Glass passivated junction
Low inductance
High temperature to reflow soldering guaranteed: 260°C/40sec
V_BR @ T_J = V_BR@25°C x (1+αT x (T_J - 25))(αT:Temperature Coefficient, typical value is 0.1%) Coefficient, typical value
UL Recognized epoxy meeting flammability rating V-0
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-STD 609A.01)

Applications

TVS Components are ideal for the protection of I/O Interfaces, V_CC bus and other vulnerable circuits used in Telecom, Computer, Industrial and Consumer electronic applications.
