Product Description
STMicroelectronics 1.5KE56A is a 1-Element Uni-Directional Transient Voltage Suppressor (TVS) Diode engineered for protection against voltage spikes in electronic circuits. Rated at 1500 W peak pulse power dissipation, this diode features a robust single-element configuration optimized for suppressing transient voltages and safeguarding sensitive components.
The diode is housed in a DO-201 axial through-hole package, measuring 9.5 mm in length and 5.3 mm in diameter and width, making it ideal for installation on printed circuit boards where axial lead devices are required.
With a minimum breakdown voltage of 53.2 V and a maximum reverse standoff voltage of 47.8 V, the 1.5KE56A provides effective clamp voltage protection at 100 V to prevent voltage surges from damaging downstream electronics. The device operates reliably in extreme environmental conditions with certified temperature rating from -65°C to +175°C.
The 2-pin diode supports a maximum peak pulse current of 100 A, allowing it to absorb high energy transients resulting from inductive load switching, lightning strikes, and electrostatic discharge. Although it does not have specialized ESD protection, its rugged design and UL 497B approval (File number: QVGQ2.E136224) attest to its suitability for industrial and commercial electronic applications.
This uni-directional TVS diode is widely used in power supplies, communication equipment, automotive electronics, and other applications requiring transient overvoltage protection.
Single element uni-directional diode configuration for effective suppression. 1500 W surge power capacity for high reliability. Complies with UL 497B for safety and performance assurance. Through-hole axial DO-201 package for ease of mounting.
Wide temperature range supports harsh industrial environments.
