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 +VCCand 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.
The Bourns
device will meet IEC 61000-4-2 (ESD), IEC 61000-4-4
(EFT) and IEC 61000-4-5 (Surge) requirements.
