P6KE24CA Bidirectional TVS Diode DO-204AC

P6KE24CA Bidirectional TVS Diode provides superior overvoltage protection for sensitive electronic components by clamping high-voltage transients before they can cause permanent damage. This bidirectional Transient Voltage Suppressor (TVS) specifically handles alternating current (AC) signals or data lines where voltage swings occur in both directions. Furthermore, the device features a high peak pulse power dissipation of 600 Watts, ensuring robust defense against Induced Lightning (L) and Electrostatic Discharge (ESD). Consequently, engineers rely on this diode for its ultra-fast response time, which typically measures less than 1.0 picosecond. Therefore, integrating the P6KE24CA into your PCB design significantly increases system reliability and longevity in electrically noisy environments.

Key Features:

• Bidirectional Protection: Protects circuits against voltage spikes in both positive and negative directions, making it ideal for AC lines and bidirectional data buses.
• High Power Handling: Dissipates up to 600 W of peak pulse power at a 10/1000 μs waveform, providing a heavy-duty safety margin.
• Fast Response: Operates with a response time of less than 1 ps from 0 Volts to V_BR min, effectively neutralizing rapid transients.
• Low Clamping Voltage: Limits the voltage across protected components to a safe level during a surge event.
• Low Leakage Current: Maintains high circuit efficiency by drawing minimal current (typically less than 1 μA) during normal operating conditions above 10V.
