Texas Instruments TSD05/TSD05C Surge Protection Device

Texas Instruments TSD05/TSD05C Surge Protection Device is designed for clamping harmful transients such as ESD and surge. The TSD05 is unidirectional and the TSD05C is bidirectional. The TSD05/TSD05C is rated to dissipate ESD strikes up to ±30kV (contact and air gap discharge) and also meets the maximum level specified in the IEC 61000-4-2 international standard (Level 4). For surges, the device can clamp 8/20µs surges with peak currents up to 60A (TSD052) and 30A (TSD05C) following the IEC 61000-4-5 standard.

This device also features a 19pF (TSD05) or 4pF (TSD05C) (typical) IO capacitance, enabling it to protect data and high-speed data lines. The low dynamic resistance and low clamping voltage provide system-level protection against transient events. Combining this device's robust clamping performance and low capacitance, TSD05/TSD05C is an excellent TVS diode to protect data and power lines in many different applications. The Texas Instruments TSD05/TSD05C is offered in the industry standard, leaded SOD-323 package to enable easy solderability.
