ESDALC5-1BM2, ESDALC5-1BT2Single-line low capacitance Transil™,
transient surge voltage suppressor (TVS) for ESD protection
Datasheet − production data
Features Single-line low capacitance Transil diode Bidirectional ESD protection Breakdown voltage VBR = 5.8 V min. Low diode capacitance (26 pF typ at 0 V) Low leakage current < 60 nA at 5 V Very small PCB area: 0.6 mm²
Benefits High ESD protection level High integration Suitable for high density boards Lead-free packages ECOPACK® 2 compliant components
Complies with the following standards: IEC 61000-4-2 (exceeds level 4) 30 kV (air discharge) 30 kV (contact discharge) MIL STD 883G - Method 3015-7: class 3 Human body model
ApplicationsWhere transient overvoltage protection in ESD
sensitive equipment is required, such as: Computers Printers Communication systems Cellular phone handsets and accessories Video equipment
DescriptionThe ESDALC5-1BM2 and ESDALC5-1BT2 are
bidirectional single-line TVS diodes designed to
protect data lines or other I/O ports against ESD
transients.
These devices are ideal for applications where
both reduced line capacitance and board space
saving are required.
