Introduction

TS2521PBX is a low-capacitance Transient Voltage Suppressor (TVS ) array designed to provide electrostatic discharge (ESD ) protection for high - speed data interfaces. With typical capacitance of 3.0pF only, TS2521PBX is designed to protect parasitic-sensitive systems against over-voltage and over-current transient events. It complies with IEC 61000-4-2 (ESD), Level 4 (±15kV air, ±8kV contact discharge), IEC 61000-4-4 (electrical fast transient - EFT) (40A, 5/50 ns), IEC 61000-4-5 (Surge) (23 A, 20μs), very fast charged device model (CDM) ESD and cable discharge event (CDE), etc. TS2521PBX is in a uDFN-2L package. Each TS2521PBX device can protect one high-speed line pair. The “flow-thru” design minimizes trace inductance and reduces voltage overshoot associated with ESD events. The combined features of low capacitance and high ESD robustness make TS2521PBX ideal for portable applications such as cellular phones and MP3 players. The low clamping voltage of the TS2521PBX guarantees a minimum stress on the protected IC.
