The 1.5KE51ARL4 is a unidirectional Zener TVS diode from On Semiconductor, part of the Mosorb series. It is designed to protect sensitive electronic components from high-voltage, high-energy transients with a peak power dissipation of 1500W. The device features a clamping voltage of 70.1V at a peak pulse current of 21.4A, ensuring robust surge protection.
The device offers an ESD rating of Class 3 (>16 kV) per the Human Body Model and a response time of typically less than 1 ns. It is UL 497B recognized for isolated loop circuit protection. The operating temperature range spans from -65°C to 175°C, making it suitable for harsh environments.
The 1.5KE51ARL4 is housed in a DO-201AD axial package, which is void-free, transfer-molded, and thermosetting plastic. The leads are corrosion-resistant and readily solderable, with a maximum lead temperature of 260°C for 10 seconds. Mounting is through-hole, and the cathode is indicated by a polarity band.
This TVS diode is ideal for general-purpose transient protection in applications such as communication systems, numerical controls, process controls, medical equipment, business machines, and power supplies. It provides reliable protection for CMOS, MOS, and bipolar integrated circuits.
