Littelfuse – SP1015 Series TVS Diode Array
TVS Diode Arrays from Littelfuse Combine ESD Protection, Low Dynamic Resistance
Ideal for protecting micro-SIM interfaces, touchscreen interfaces on smartphones, wearables, tablets, and eReaders
The SP1015 Series TVS Diode Array from Littelfuse offers ESD protection for up to four data lines in one compact flip chip package. These robust diodes can safely absorb repetitive ESD strikes well above the maximum level specified in the IEC61000-4-2 international standard without performance degradation. Their bidirectional configuration provides symmetrical ESD protection for data lines when AC signals are present. With just 0.65Ω of dynamic resistance, the SP1015 Series supports the low clamping voltage needed to protect the small-geometry integrated circuits used in modern electronic devices. Applications include protection for micro-SIM interfaces, touchscreen controllers I2C lines,and general purpose I/Os on smartphones, wearable devices, tablets, and eReaders.
Features
- μSIM protection—Four lines of ESD protection mating perfectly next to a μSIM socket
- Bidirectional protection with standoff voltages suitable to protect touchscreens as large as 6 inches
- Promotes high ESD immunity and superior protection: ESD, IEC 61000-4-2, ±20kV contact, ±30kV air discharge; EFT, IEC 61000-4-4, 40A; Lightning, IEC 61000-4-5, 2A
- Very low dynamic resistance of 0.65Ω
- Flexible ground connection; any I/O pad will work
- Permits back-to-back 5V standoff
Benefits
- Four ESD diodes in a 0.93×0.53mm footprint represents an improvement over previous implementations, saving PCB area/cost
- ESD protection beyond the maximum rating in the IEC61000-4-2 standard gives customers more design margin and higher end-product reliability in the field
- Supports low clamping voltage needed for protecting modern electronics filled with small-geometry ICs
- Standoff voltages enable protection of 95% of all interfaces
Typical Target High-Speed Applications
