Product Description
STMicroelectronics 1.5KE18A is a 1-Element Uni-Directional Transient Voltage Suppressor (TVS) diode designed for protecting sensitive electronic circuits from voltage spikes and transient surges. With a peak pulse power dissipation of 1.5 kW and a 2-Pin DO-201 axial lead package, it offers reliable transient voltage clamping performance suitable for industrial and commercial electronic equipment protection.
This TVS diode features a single diode configuration with unidirectional voltage suppression capability, ideal for protecting against positive voltage transients. It boasts a minimum breakdown voltage of 17.1 V and a maximum reverse stand-off voltage of 15.3 V, ensuring precise protective response thresholds.
The device supports a maximum peak pulse current of 308 A and provides a clamping voltage of 32.5 V, efficiently clamping transient surges and safeguarding downstream components. Its low maximum reverse leakage current of 1 μA reduces standby power consumption and electrical noise.
Operating over an extended temperature range from -65°C to 175°C, the 1.5KE18A ensures reliable operation under harsh environmental conditions. The through-hole mount type and standard DO-201 package dimensions of 9.5 mm length and 5.3 mm diameter facilitate straightforward mounting on printed circuit boards, promoting manufacturing process efficiency.
This component is widely applicable in power supply circuits, communications, industrial controls, and other electronic applications requiring robust transient voltage suppression. It contributes to enhancing circuit longevity and overall system reliability by effectively dissipating voltage spikes caused by inductive load switching, lightning surges, and electrostatic discharge.
