Steering Diode Structure ESD Protection Array
Small Signal Diode
Applications Information
TESDS5V0ALC incorporates eight surge rated, low capacitance steering diodes and a TVS diode in a single package
During transient conditions, the steering diodes direct the transient to either the positive side of the power supply line or to ground
The internal TVS diode prevents over-voltage on the power line, protecting any downstream components
Circuit Board Layout Recommendations
Data Line Protection Using Internal TVS Diode as Reference
Designed to protect protect high speed data interfaces
Data Line and Power Supply Protection Using Vcc as reference Data Line Protection with Bias and Power Supply Isolatio
n
Designed to protect four data lines from transient over-voltages by clamping them to a fixed reference
To protect data lines and the power line, connect pin 5 directly to the VDD. In this configuration the data lines are referenced to
the supply voltage. The internal TVS diode prevents over-voltage on the supply rail.
The TESDS5V0ALC can be isolated from the power supply by adding a series resistor between pin 5 and VDD. A value of 100kΩ is
recommended. The internal TVS and steering diodes remain biased, providing the advantage of lower capacitance.
²In applications where no positive supply reference is available, or complete supply isolation is desired, the internal TVS may
be used as the reference. In this case, pin 5 is not connected. The steering diodes will begin to conduct when the voltage
Designed to protect protect sensitive components which are connected to data and transmission lines from overvoltage caused by
electrostatic discharge (ESD), electrical fast transients (EFT), and lightning.

Tape & Reel specification
Suggested PAD Layout
Note 1: A0, B0, and K0 are determined by component size. The clearance between the components and the cavity must be
within 0.05 mm min. to 0.5 mm max. The component cannot rote more than 10 o within the determined cavity.
Note 2: If B1 exceeds 4.2 mm(0.165'') for 8 mm embossed tape, the tape may not feed through all tape feeders.
Note 3: The suggested land pattern dimensions have been provided for reference only, as actual pad layouts
may vary despending on application.
