Littelfuse 15KE33CA Transient Voltage Suppressor Diode

The 1.5KE33CA is an axial leaded, bidirectional Transient Voltage Suppressor TVS diode with lead-free, matte tin-plated terminals and a molded plastic body. Designed to protect sensitive electronic equipment from voltage transients caused by lightning and other transient events, it is ideal for safeguarding I/O interfaces, VCC buses, and other vulnerable circuits in telecom, communications, networking, computers, industrial applications, and consumer electronics. The device features a glass-passivated junction for excellent clamping capability, low incremental surge resistance, and a typical failure mode of short circuit from over-voltage or over-current conditions. It is halogen-free, with a test current of 1mA and a maximum reverse leakage current of 1μA.
