Automotive 10-pF, ±9-V, ±20-kV ESD protection diode in 0402 package

The TPD1E10B09-Q1 device is a bidirectional electrostatic discharge (ESD) transient voltage suppression (TVS) diode in a small 0402 industry standard package. This TVS protection diode is convenient for component placement in space-saving applications and features low R DYN and high IEC rating. The TPD1E10B09-Q1 is rated to dissipate ESD strikes above the maximum level specified in the IEC 61000-4-2 international standard (Level 4) offering ±20-kV contact discharge and ±20-kV IEC air-gap protection. ESD voltages can easily reach 5-kV and during extreme conditions these voltages can be significantly higher, causing damages to many integrated circuits. For example, in a low humidity environment voltages can exceed 20-kV.

The low dynamic resistance (0.5 Ω) and low clamping voltage (13 V at 1-A IPP) allows for system level protection against transient events, providing robust protection on designs that are exposed to ESD events. This device also features a 10-pF IO capacitance making it an excellent choice for audio lines, push buttons, memory interfaces, or GPIOs.

This device is also available without automotive qualification: TPD1E10B09.
