1.5KE400CA ST Transient Voltage Suppressors (TVS)

The 1.5KE400CA is a bidirectional TVS diode in a DO-201 package, offering 1500W peak pulse power dissipation for high-voltage circuit protection. For selection, verify the reverse standoff voltage of 342V, breakdown voltage from 380V to 420V at 1mA, and ensure the clamping voltage is within the protected circuit's tolerance . The 1.5KE series is characterized by glass passivated junction technology for high reliability, fast response time (<1ps), and excellent clamping capability. Operating temperature range spans -55°C to +175°C. Applications include high-voltage AC/DC power supply lines, industrial equipment, telecom infrastructure, energy metering, solar inverter input protection, and any system operating on 220V/380V AC mains requiring robust surge protection against lightning and switching transients.
