LESD8D3.3CBT5G

LESHAN RADIO COMPANY, LTD. Transient Voltage Suppressors for ESD Protection General Description The LESD8D3.3CBT5G is desined to protect voltage sensitive components from ESD and transient voltage LESD8D3.3CBT5G events. Excellent clamping capability, low leakage, and fast response time, make these parts ideal for ESD 1 protection on designs where board space is at a premium. Because of it's small size, it is suit for using in cellular phones, MP3 players, digital cameras and many other portable applications where board space is at a premium. 2 SOD882 Applications Cellular phones Portable devices Digital cameras Power supplies 1 Features 2 Ordering information Small Body Outline Dimensions Low Body Height Peak Power up to 105 Watts @ 8 x 20μs Pulse Low Leakage current Response Time is Typically < 1 ns Device Marking Shipping LESD8D3.3CBT5G DA 10000/Tape&Reel ESD Rating of Class 3 per Human Body Model Absolute Ratings (Tamb=25°C ) Symbol Parameter Value Units PPP Peak Pulse Power (tp = 8/20μs) 105 W TL Maximum lead temperature for soldering during 10s 260 °C Tstg Storage Temperature Range -55 to +150 °C Top Operating Temperature Range -55 to +150 °C Tj Maximum junction temperature 150 °C ±30 ±30 KV 40 A IEC61000-4-2 (ESD) IEC61000-4-4 (EFT) Nov. 2019 air discharge contact discharge Rev.F 1/4 LESHAN RADIO COMPANY, LTD.
