1.5KE150A
The 1.5KE150A is a high-power Transient Voltage Suppressor (TVS) diode manufactured by SMC Diodes. This unidirectional device is designed to protect sensitive electronic circuits from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). With a power dissipation rating of 1500W, the 1.5KE150A effectively clamps transient voltages to a safe level, preventing damage to downstream components. Its 128V clamping voltage ensures reliable protection. Housed in a DO-201 package, this TVS diode is easy to install and integrate into existing designs. Supreme Components International is an authorised distributor of SMC Diodes, ensuring you receive authentic and high-quality components. This diode is suitable for various applications, including automotive, industrial, and consumer electronics.
