When a transient voltage exceeds the breakdown voltage, the diode instantly conducts, clamping the voltage to a safe level and diverting surge current away from sensitive components. Once the transient passes, the diode returns to its high-impedance state.\u003c\/p\u003e\n\u003ch3\u003ePackage Contents\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x 1.5KE400A TVS Diode\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eInstall the TVS diode in parallel with the circuit or component you want to protect.
