1.5KE39CA, 39V Bidirectional TVS Diode, 1500W, DO-201

The 1.5KE39CA is a bidirectional TVS (Transient Voltage Suppression) diode designed to protect sensitive electronics from high-voltage transients and ESD. With its 39V breakdown voltage and 53.9V clamping capability, this device is widely used in industrial controls, telecommunication equipment, power supplies, and consumer electronics. The axial DO-201 package allows easy through-hole mounting in high-energy environments.

Key Features:

• High Power Handling: Absorbs up to 1500W of peak pulse power (10/1000 µs waveform).
• Bidirectional Transient Protection: Ideal for AC lines or bidirectional transient sources.
• Fast Response Time: <1 ns clamping response protects sensitive circuits.
• Glass Passivated Junction: Ensures stability and ruggedness in harsh environments.
