Features and Benefits ■ 200W peak pulse power capability at 10/1000µs waveform, repetition rate (duty cycle): 0.
01% ■ 1200W peak pulse power capability at 8/20us waveform ■ EFT protection of data lines in accordance with IEC 610004-4 ■ Fast response time: typically less than 1.
0ns from 0 Volts to VBR min ■ Excellent clamping capability ■ Compatible with industrial standard package SOD-123FL ■ Low profile: maximum height of 1.
08mm.
■ For surface mounted applications to optimize board space ■ High temperature soldering: 260°C/30 seconds at terminals ■ Built-in strain relief ■ Meet MSL level1, per J-STD020C, LF maximun peak of 260°C ■ Matte tin lead–free plated ■ 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 ■ IEC 61000-4-2 ESD 30kV(Air), 30kV (Contact) ■ Halogen-free and RoHScompliant ■ Pb-free E3 means 2nd level interconnect is Pb-free and the terminal finish material is tin(Sn) (IPC/JEDEC J-STD609A.
01) ■ ESD protection of data lines in accordance with IEC 61000-4-2 Applications SMF3.
