Littelfuse SP0503BAHTG ESD Protection TVS Diode Array, SOT-143, 5.5V

The Littelfuse SP0503BAHTG is a monolithic, 3-channel TVS (Transient Voltage Suppression) diode array designed to protect sensitive electronic circuits from destructive electrostatic discharge (ESD) and transient overvoltage events. It features a silicon construction with a moulded epoxy body and copper/iron alloy leads, providing a robust surface-mount solution for high-speed data, signal, and control lines.

This device is engineered to meet stringent international standards for electromagnetic compatibility, specifically the IEC 61000-4-2 standard for electrostatic discharge immunity. Its fast response time of less than 1 nanosecond ensures immediate clamping of transient spikes, safeguarding analogue or digital input circuits operating at voltages up to 5VDC. The tailored silicon structures are optimised for superior transient protection with minimal signal integrity impact.

Key to its performance in high-frequency applications is its exceptionally low typical input capacitance of 30pF, which prevents signal attenuation and distortion. Combined with a low reverse standoff leakage current of 100nA and a wide operating temperature range from -55°C to 125°C, this TVS array offers reliable protection in demanding environments.
