General Information

Electrical and Thermal Characteristics (@ TA = 25 °C Unless Otherwise Noted)

Notes:

1. See Peak Pulse Power vs. Pulse Time.

2. From Pin 4 to Pin 1.

3. See Pulse Wave Form.

4. From Pin 1 to Pin 3, Pin 1 to Pin 2, Pin 3 to Pin 4, Pin 2 to Pin 4.

5. GND is connected to ground, REF is connected to +VCC and input applies to VCC = 12 V. Vstgn = 30 mV, F = 1 MHz.

The CD143A-SR05 and CD143A-SR12 devices provides ESD, EFT

and surge protection for the external ports of portable electronic

devices such as cell phones, handheld electronics and personal

computers.

The ESD protection provided by the component enables a data

port to withstand a minimum ±8 KV Contact / ±15 KV Air Discharge

per the ESD test method specified in IEC 61000-4-2. The device

measures 2.80 mm x 1.20 mm and is available in a SOT-143

package intended to be mounted directly onto an FR4 printed

circuit board.
