Littelfuse 9-Element Uni-Directional TVS Diode Array 6-Pin SOT-23 SP0504SHTG

Littelfuse SP0504SHTG is a 9-element Uni-Directional TVS Diode Array designed for advanced electrostatic discharge protection of electronic circuits. Packaged in a compact 6-pin SOT-23 surface mount format, this device provides a high level of protection for sensitive I/O lines while maintaining minimal loading capacitance.

The diode array features ultra-low capacitance rail-to-rail diodes and a complementary zener diode fabricated using proprietary silicon avalanche technology. This combination allows the device to safeguard digital communication lines such as HDMI, USB 2.0, DVI, and IEEE 1394 interfaces against destructive ESD strikes and electrical fast transients.

With a minimum breakdown voltage of 6 V and a maximum reverse standoff voltage of 6 V, the SP0504SHTG can clamp transient voltages at 13 V while enduring a peak pulse current of 4.5 A. The maximum operating temperature rating of 125°C extends its usability in industrial and automotive electronics.

This device is automotive-grade with AEC-Q101 qualification, meeting stringent quality and reliability standards expected in automotive electronic applications. Its low leakage current (max 500 nA) and tight dimensional profile (3 mm length × 1.75 mm width × 1.3 mm height) enable it to be integrated seamlessly into compact PCB designs.

Common application areas include computer peripherals, mobile phones, PDAs, digital cameras, network hardware, test equipment, and medical devices. The array helps in protecting sensitive electronics from damage due to ESD, EFT, and lightning surges while preserving signal integrity for high-speed data lines.

Manufactured in Thailand, this diode array combines compactness with robust electrical characteristics, making it suitable for various industrial, laboratory, automotive, and commercial electronic system designs.
