TSM24CA ±24V Low Capacitance Surge Diode for Industrial Networks
in SOT-23 Package

1 Features

Protection against 1kV, 42Ω IEC 61000-4-5 surges for automotive signal lines
Robust surge protection:
- IEC 61000-4-5 (8/20µs): 30A
Low clamping voltage of 40V at 24A for 8/20µs surge current protects downstream components
Bidirectional polarity to support positive and negative voltage swings and miswiring conditions
± 24V working voltage for protecting signals on 12V systems
Low I/O Capacitance: 12pF (typical)
Low leakage current of 75nA (maximum)
Integrated IEC 61000-4-2 ESD protection:
- ±30kV contact discharge
- ±30kV air-gap discharge
Small SOT-23 leaded package to minimize board space and allow for automatic optical inspection (AOI)
