LESHAN RADIO COMPANY, LTD.
Transient Voltage Suppressors for ESD Protection
General Description
LESD9D3.3CT5G
S-LESD9D3.3CT5G
The LESD9D3.3CT5GG is designed to protect voltage
sensitive components from ESD and transient voltage
events. Excellent clamping capability, low leakage, and
fast response time, make these parts ideal for ESD
protection on designs where board space is at a
premium. Because of its small size, it is suited for use
in cellular phones, MP3 players, digital cameras and
many other portable applications where board space is
at a premium.
