PRODUCTION DATA
The TPD1E10B09-Q1 is a single-channel back-to-back diode that protects one bidirectional signal line from electrostatic discharge and surge pulses. Because the diode is bidirectional, the TPD1E10B09-Q1 protects signals that have positive or negative polarity. During normal operation, the diode behaves as a 10-pF capacitance to ground. Board layout is critical for optimal performance of any diode.
Placement: The diode must be placed very close to the external connector for optimal performance. Ideally, the diode must be placed on the line that it is protecting.
Layout: Pin 1 of the diode must be right over the protected signal line. There must a thick and short trace from pin 2 to ground. An example is shown in the Layout section.
