Littelfuse 1.5KE Series Silicon Avalanche Diode Datasheet
The 1.5KE Series silicon avalanche diodes are designed to protect sensitive electronic equipment from voltage transients such as lightning. They are suitable for I/O interfaces, Vcc buses and other vulnerable circuits in telecom, computer, industrial and consumer electronics.
Key features include 1500 W surge capability at a 10/1000 µs waveform, a voltage range of 6.8 V to 550 V, uni‑directional and bi‑directional options, and a glass‑passivated chip junction in a DO‑201 axial leaded package. The devices are RoHS compliant and offer low Zener impedance and typical reverse leakage below 1 µA above 10 V.
