TVS (Transient Voltage Suppressors) are solid state components that protect circuits from electrical transients such as ESD events, lightning, or electrochemical interference. The P3100ADL61 is a TVS diode manufactured by Diodes Incorporated, specifically designed for filtering high speed ESD (Electrostatic Discharge) and EMI (Electromagnetic Interference).

The P3100ADL61 is a three-lead, surface-mount device that provides bi-directional protection against ESD events. Its simple structure consists of two low voltage clamping zones and two internal series resistors: one between the cathode and anode; and the other between the anode and ground. The device features an operating temperature ranging from -65°C to +150°C, a transient peak pulse current of 30 Amps, and a 2.5kV ESD protection level.

The P3100ADL61 is primarily used in wireless (WLAN) and hand-held applications such as PDAs, cellular phones, MP3 players, cameras, and laptop computers. Its low profile design makes it one of the most popular components for design engineers who have space constraints and high current requirements. Additionally, the device offers superior immunity to ESD and EMI in designs.

The P3100ADL61 works by limiting the voltage across itself when a current surge is applied. The two series resistors act as a clamp, limiting the rise time and peak current of the voltage waveform. This occurs by shunting the current flow away from sensitive components such as integrated circuits and onto the TVS diode. The higher the voltage across the diode, the lower the circuit currents. Thus, damage to sensitive components in the circuit is prevented.

The P3100ADL61 combines a combination of high-performance protection features, such as low capacitance, low clamping voltage, and high peak pulse current handling. It is an ideal solution for design engineers looking for an ESD protection device that provides superior performance without sacrificing design flexibility. The P3100ADL61 is an excellent choice for protecting sensitive components in high-speed, hand-held electronics and most other applications.
