P6KE24CA Transient Voltage Suppressor (TVS) Diode

The P6KE24CA is a bidirectional transient voltage suppressor manufactured by Diotec (and other vendors) designed to protect sensitive electronics from high-voltage transients. Unlike the unidirectional "A" version, the "CA" version features a bidirectional configuration, allowing it to protect against surges in both positive and negative directions, which is essential for AC lines or data buses carrying bipolar signals. With a 600 Watt peak power rating, it acts as a high-speed clamp that switches from high impedance to low impedance when the breakdown voltage is exceeded. It is commonly used in microprocessor protection, telecommunications, and industrial control systems to safeguard against electrostatic discharge (ESD) and inductive load switching. While the user mentioned "20A 24V," the actual rated breakdown starts at 21.6V, and its peak current capacity is approximately 18.1A under standard test waveforms.

Key Features:

Breakdown Voltage (VBR): 21.6 Volts (minimum) to 26.4 Volts (maximum).

Peak Pulse Power Dissipation (PPPM): 600 Watts at 10/1000 microsecond waveform.

Maximum Clamping Voltage (VC): 33.2 Volts at peak pulse current.

Peak Pulse Current (IPP): 18.1 Amperes.

Polarity: Bidirectional (indicated by the "CA" suffix).
