TSM24CA
- 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)
The TSM24CA is a low-capacitance TVS diode and is part of TI’s surge protection device family. The TSM24CA robustly shunts up to 30A of IEC 61000-4-5 (8/20 µs) fault current to protect systems from high power transients or lightning strikes. The device offers a solution to the common industrial signal line EMC requirement to survive up to 1kV IEC 61000-4-5 open circuit voltage coupled through a 42Ω impedance, clamping that surge at 40V (I PP = 24A). The TSM24CA also has a very low line capacitance of 12pF which allows it to protect common automotive communication networks like CAN from surges in EV charging applications.
Additionally, the TSM24CA is available in a small leaded SOT-23 (DBZ) package which is reduced in size by approximately 50 percent compared to the industry standard SMA package. The extremely low device leakage and capacitance provide a minimal effect on the protected line.
