TPSMB170CA

The TPSMB170CA is a bi-directional transient voltage suppression diode designed to protect high speed communication interfaces from voltage transients caused by electro-static discharge (ESD). It is a surface-mount device, available in the industry-standard SMA package. With its low clamping voltage and excellent peak pulse power capability, the TPSMB170CA is an ideal solution for protecting sensitive components in high speed communication applications such as 10/100/1000BASE-T, USB 2.0, SmartPhones, and PDAs.

The TPSMB170CA device is a two-terminal, bi-directional, transient voltage suppressor diode. The anode and cathode are the main terminals, with the anode being the positive and the cathode being the negative. When a positive voltage is applied to the anode, the device will shut off until the voltage reaches the trigger voltage level (Vt). Once the voltage reaches Vt, the diode will turn on and begin to suppress the voltage transients.

When a negative voltage is applied to the cathode, the device will again shut off until the voltage reaches the trigger voltage level (Vt). Once the voltage reaches Vt, the diode will turn on and begin to suppress the voltage transients. The TPSMB170CA is designed to protect against ESD operating from 4kV to 8kV, with a peak pulse power rating of up to 25W.

The TPSMB170CA also features a low capacitance of 1pF (typical) which helps to minimize signal loss due to diode capacitance in high speed communication applications. The low capacitance also minimizes the EMI/RFI noise generated in such applications. In addition, the TPSMB170CA has a very low leakage current of 1uA (max). This allows the device to be used in applications that require an ultra-low leakage current.

In summary, the TPSMB170CA is an ideal solution for protecting high speed communication applications from electro-static discharge. With its low clamping voltage, excellent peak pulse power capability, low capacitance, and ultra-low leakage current, the TPSMB170CA provides the best-in-class protection for your sensitive devices.
