P6KE250CA

The P6KE250CA from Littelfuse Inc. is a 600W bidirectional Transient Voltage Suppression (TVS) diode designed to protect sensitive electronic equipment from voltage transients. This component features a reverse standoff voltage of 214V and a maximum clamping voltage of 344V under a 10/1000μs test waveform. With a peak pulse current rating of 1.8A and a response time of less than 1 ps, it provides fast and effective clamping for overvoltage events.

The device is housed in a DO-204AC (DO-15) axial-lead through-hole package, making it suitable for automated insertion and high-reliability applications. It offers a steady state power dissipation of 5.0W on an infinite heat sink and an operating junction temperature range from -55°C to 175°C. The P6KE250CA is compliant with RoHS, halogen-free, and lead-free, and meets IEC 61000-4-2 ESD requirements up to 30kV (air and contact).

Typical applications include general-purpose transient protection in telecom, computer, industrial, and consumer electronics. The bidirectional configuration allows it to protect both positive and negative voltage surges without polarity concerns. The device's glass passivated chip junction ensures reliability, and its low incremental surge resistance and excellent clamping capability make it a suitable choice for I/O interfaces and VCC bus protection.
