The BSPD300480Y2P from SEPCON is a two-channel module for the protection of signal and supply lines in applications where a mixture of TVSs and small capacitors are utilized. The module offers some attractive features that make it suitable for a wide range of applications, such as consumer electronics, automotive, industrial, and medical. The use of advanced silicon technology and the proven low capacitance ceramic-glass wall design offer optimal performance.

The BSPD300480Y2P module combines two low capacitance TVSs (Transient Voltage Suppressor, or TVS, is a device, usually a diode, designed to protect against excessive over-voltage) with two small capacitor arrays (including one ELP (Equivalent Low Passance) capacitor) in a low profile and space-saving package. The two TVSs protect against power and signal over-voltage, while the two ELP capacitors provide EMI (electromagnetic interference) and RFI (Radio Frequency Interference) protection. The module also features an integrated built-in protection scheme that helps to reduce the likelihood of an excessive overload condition.

The BSPD300480Y2P module is designed to operate in an environment of up to 300 VDC supply voltage and peak current of up to 4A. The module has to be programmed appropriately for any given application, so that the appropriate peak current can be smoothly adjusted and the appropriate level of EMI/RFI protection is achieved. The integrated EMI/RFI protection achieved by the module helps to reduce the radiated and conducted emissions, minimizing the need for additional components in the system.

The working principle of the BSPD300480Y2P module is as follows: when an over-voltage condition appears on the supply or signal line, the two TVSs in the module will be activated and will clamp the over-voltage down to a safe level. The two small capacitor arrays will then act as EMI/RFI filters and will help to suppress any remaining interference that might have been caused by the over-voltage. In addition, the module also features a built-in protection scheme that helps to prevent over-loading of the module during high frequency transients.

Overall, the BSPD300480Y2P module is a great option for protecting against over-voltage on supply and signal lines in applications that require a combination of TVSs and small capacitors. The integrated protection scheme and the low capacitance design of the module make it a great solution for any kind of application where peak current and conducted/radiated emissions must be minimized.
