    • IEC61000-4-5 (8/20 µs): 20 A
  • Low clamping voltage of 33 V (typical) at 20 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 24 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 TSM24B is a part of TI’s surge protection device family. The TSM24B robustly shunts up to 20 A of IEC 61000-4-5 fault current to protect systems from high power transients or lightning strikes. The TSM24B is rated to dissipate ESD strikes beyond the maximum level specified in the IEC 61000-4-2 international standard (±30-kV contact, ±30-kV air-gap). The TSM24B clamps during a surge event, keeping system exposure below 33 V (typical) at I PP = 20 A.

Additionally, the TSM24B 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.
