P4SMA16CA

The P4SMA16CA is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed to protect sensitive electronic components from voltage spikes and transients. This device is particularly useful in applications where overvoltage protection is critical, such as in telecommunications, automotive electronics, and consumer electronics.

Key Features:

1. Type and Configuration: The P4SMA16CA is a unidirectional TVS diode, which means it is designed to clamp voltage in one direction, providing effective protection against positive voltage transients.

2. Peak Power Rating: It has a peak power rating of 400 watts, which allows it to absorb significant energy from transient events without failing.

3. Reverse Stand-Off Voltage (V_RWM): The device has a reverse stand-off voltage of 16 volts, meaning it can operate normally at this voltage without conducting. When the voltage exceeds this level, the diode will begin to conduct and clamp the voltage to a safe level.

4. Clamping Voltage (V_C): The clamping voltage is specified at a certain peak pulse current, ensuring that during a transient event, the voltage across the device remains within safe limits to protect downstream components.

5. Capacitance: The P4SMA16CA features low capacitance, which is crucial for high-speed data lines, as it minimizes signal distortion and maintains signal integrity.

6. Package Type: The diode is typically housed in a DO-214AA (SMA) package, which is a surface-mount device (SMD) that allows for easy integration into various circuit designs. The package is designed for efficient thermal dissipation and robust performance.

7. Operating Temperature Range: The device can operate over a wide temperature range, making it suitable for various environmental conditions.

8. Applications: Common applications include ESD protection, surge protection in power lines, and safeguarding sensitive components in automotive and industrial electronics.

Electrical Characteristics:

• Maximum Reverse Voltage: 16V
• Peak Pulse Power: 400W (for 10/1000μs waveform)
• Clamping Voltage: Specified at different peak pulse currents
• Capacitance: Low capacitance value, typically in the range of a few picofarads

Benefits:
