PS04LTVA1 PolySurg™ LTV Series ESD Suppressor


The PolySurg™ PS04LTVA ESD Suppressors protect valuable high-speed data circuits with sensitive ICs from ESD damage without distorting data signals as a result of its ultra-low (0.05pF typical) capacitance.
• Low trigger voltage and clamping voltage delivers enhanced ESD protection of very sensitive ICs
• Ultra-low capacitance (0.05pF typ.) ideal for high speed data applications
• Provides ESD protection with fast response time (<1ns) allowing equipment to pass IEC 61000-4-2 level 4 test
• Single line, bidirectional device for placement flexibility
• Low profile 0402/1005 design for board space savings
• Low leakage current (<0.1nA typ.) reduces power consumption
• RoHS compliant, halogen free and lead free for global acceptance
• Tin-plated (Sn) version available
• Tested to meet automotive specifications (AEC-Q200)

• Satellite / digital radio • Security equipment
• Mobile phones • Broadband network equipment
• GSM Modules • Other RF applications
• HDTV Equipment • High speed data ports
• A/V Equipment - USB 2.0/3.0
• DMB Modules - IEEE 1394
• Test and measurement equipment - HDMI
• Portable game systems - DVI
• Personal media players - High speed ethernet
• 10,000 pieces in paper tape on 7 inch diameter (178mm) reel.

2. Trigger measurement made using Transmission Line Pulse (TLP) method.
3. Minor shifting in characteristics may be observed over multiple ESD pulses at very rapid rate.

Device Marking
PolySurg™ ESD Suppressors are marked on the tape and reel packages, not individually. Since the product is bi-directional and symmetrical, no orientation marking is required.
Design Consideration
The location in the circuit for the LTV series has to be carefully determined. For better performance, the device should be placed as close to the signal input as possible and ahead of any other component. Due to the high current associated with an ESD event, it is recommended to use a “0-stub” pad design (pad directly on the signal/data line and second pad directly on common ground).
