TSM24A-Q1
- Robust surge protection:
- IEC61000-4-5 (8/20 µs): 60 A
- Low clamping voltage of 38 V (typical) at 60 A for 8/20 µs surge current protects downstream components
- Unidirectional polarity for optimized clamping performance on single-ended data lines and power rails
- 24 V working voltage for protecting signals on 12-V systems
- Low leakage current of 75 nA (maximum)
- Low I/O capacitance of 54 pF (typical)
- Integrated IEC 61000-4-2 ESD protection
- ±30-kV contact discharge
- ±30-kV air-gap discharge
- Small SOT-23 leaded package to minimize board space and allow for automatic optical inspection (AOI)
The TSM24A-Q1 is a part of TI’s surge protection device family. The TSM24A-Q1 robustly shunts up to 60 A of IEC 61000-4-5 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 2.5 kV IEC 61000-4-5 open circuit voltage coupled through a 42 Ω impedance. The TSM24A-Q1 clamps during a surge event, keeping system exposure below 38 V (typical) at I PP = 60 A.
Additionally, the TSM24A-Q1 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 device is designed to have a minimal effect on the protected line due to extremely low device leakage.
For the bidirectional version of this device, please see TSM24CA-Q1.
