LESD8LH5.0CT5G

LESHAN RADIO COMPANY, LTD. LESD8LH5.0CT5G Transient Voltage Suppressors ESD Protection Diodes with Ultra−Low Capacitance LESD8LH5.0CT5G 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 3 pF • Low Clamping Voltage • Small Body Outline Dimensions: • • • • • • 1 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 Mechanical Characteristics: CASE: Void-free, transfer-molded, thermosetting plastic 2 Ordering information Epoxy Meets UL 94 V−0 LEAD FINISH: 100% Matte Sn (Tin) QUALIFIED MAX REFLOW TEMPERATURE: 260°C Device Marking Shipping LESD8LH5.0CT5G A 10000/Tape&Reel Device Meets MSL 1 Requirements MAXIMUM RATINGS Rating IEC 61000−4−2 (ESD) Symbol Contact Air Value Unit ±10 ±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 Stresses exceeding Maximum Ratings may damage the device.
