LESD8LS5.0T5G

LESHAN RADIO COMPANY, LTD. LESD8LS5.0T5G Transient Voltage Suppressors ESD Protection Diodes with Ultra−Low Capacitance LESD8LS5.0T5G The ESD8L is designed to protect voltage sensitive components that require ultra−low capacitance from ESD and transient voltage events. Excellent clamping capability, low capacitance, 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 low capacitance, it is suited for use in high frequency designs such as USB 2.0 high speed and antenna line applications. 1 2 Specification Features: SOD882 • Ultra Low Capacitance 0.5 pF • Low Clamping Voltage • Small Body Outline Dimensions: • • • • • • 0.039″ x 0.024″ (1.00 mm x 0.60 mm) Low Body Height: 0.020″ (0.5 mm) Stand−off Voltage: 5 V Low Leakage Response Time is Typically < 1.0 ns IEC61000−4−2 Level 4 ESD Protection This is a Pb−Free Device CATHODE Ordering information Device MAXIMUM RATINGS LESD8LS5.0T5G Rating IEC 61000−4−2 (ESD) Symbol Contact Air ANODE Value Unit ±8 ±15 kV Total Power Dissipation on FR−5 Board (Note 1) @ TA = 25°C °PD° 150 mW Storage Temperature Range Tstg −55 to +150 °C Junction Temperature Range TJ −55 to +125 °C Lead Solder Temperature − Maximum (10 Second Duration) TL 260 °C Marking RS Shipping 10000/Tape&Reel Stresses exceeding Maximum Ratings may damage the device.
