STMicroelectronics 1.5KE120CA Bidirectional TVS Diode

The 1.5KE120CA is a high-quality bidirectional transient voltage suppressor (TVS) diode from STMicroelectronics, designed to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events. This device is part of the 1.5KE series, which is known for its reliability and efficiency in surge protection.

Constructed with high-performance materials, the 1.5KE120CA is capable of clamping and dissipating large amounts of transient energy with its 1500W (1.5KW) peak pulse power capability at 10/1000μs waveform. This ensures robust protection for your electronic circuits against severe voltage spikes. The bidirectional feature of this TVS diode provides symmetrical protection for both positive and negative voltage transients, making it an ideal choice for AC applications or where the polarity is undefined.

The device has a stand-off voltage of 120V, which means it remains non-conductive as long as the voltage across it does not exceed this threshold, ensuring minimal impact on the normal operation of the protected device. The 1.5KE120CA has a fast response time, typically in the picosecond range, offering immediate protection against transient overvoltages.

Its axial-lead package allows for easy PCB mounting and is compatible with high-volume assembly lines. The 1.5KE120CA is also RoHS compliant and adheres to ISO 9001 and ISO 14001 quality standards, confirming its environmental and manufacturing excellence. With its low leakage current and excellent clamping capability, this TVS diode is suitable for a wide range of applications, including but not limited to industrial systems, consumer electronics, power supplies, and communication systems.

By choosing the STMicroelectronics 1.5KE120CA, you are opting for a high-grade component that offers reliable protection against voltage transients, ensuring the longevity and stable performance of your electronic devices.
