The STMicroelectronics SMP50-68 is a 1-element bi-directional transient voltage suppression (TVS) diode designed to protect electronic circuits from voltage spikes and surges.
Encased in a compact 2-pin DO-214AC (SMA) surface mount package with dimensions of 4.6mm length, 2.9mm width, and 2.45mm height, this diode supports robust protection in both analogue and digital systems.
With a minimum breakdown voltage of 68V and a maximum reverse stand-off voltage of 68V, the device can withstand peak pulse currents up to 50A, making it suitable for demanding transient voltage conditions. The low leakage current of 5μA reduces power loss, enhancing the efficiency of sensitive telecommunications and industrial equipment.
The diode operates reliably over a wide temperature range from -55°C to 150°C, suitable for harsh operating environments.
The SMP50 series is optimised for use in telecom equipment protection, including xDSL, T1/E1, and ISDN line cards, providing low capacitance and high surge tolerance needed to maintain signal integrity.
High peak pulse current capacity of 50A ensures durable voltage surge suppression. Compact and standard DO-214AC (SMA) surface-mount package facilitates easy PCB assembly. Low leakage current and low capacitance enhance performance in data line protection.
Wide operating temperature range supports various industrial and telecom applications. Single element, bi-directional configuration suitable for AC and DC line protection.
This TVS Diode is an essential component in designing reliable and robust electronic circuits used in industrial electronics, telecommunications, manufacturing, and power supply systems.
