The 1.5KE Series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. 

## **Features** [Po 

- 1500W peak pulse • Low incremental surge capability at 10/1000μs resistance waveform, repetition rate • Typical IR less than 1μA (duty cycles):0.01% when VBR min>12V 

- Glass passivated chip • High temperature junction in DO-201 to reflow soldering Package guaranteed: 260°C/40sec 

- • Fast response time: / 0.375”,(9.5mm) lead typically less than 1.0ps length, 5 lbs., (2.3kg) from 0 Volts to BV min tension 

- Excellent clamping •  VBR @ TJ= VBR@25°C capability x (1+αT x (TJ - 25)) 

- •  Typical failure mode is (αT:Temperature short from over-specified Coefficient, typical value voltage or current is 0.1%) 

- Whisker test is conducted • Plastic package is based on JEDEC flammability rated V-0 per JESD201A per its table 4a Underwriters Laboratories and 4c • Matte tin lead–free plated 

- IEC-61000-4-2 ESD • Halogen free and RoHS 30kV(Air), 30kV (Contact) compliant 

- ESD protection of data • Pb-free E3 means 2nd lines in accordance with level interconnect is IEC 61000-4-2 Pb-free and the terminal 

- •  EFT protection of data finish material is tin(Sn) lines in accordance with (IPC/JEDEC J-STDIEC 61000-4-4 609A.01) 

## **Applications** Po 

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.
