DT1446-04V-7 Description

Short technical summary and product information.

The DT1446-04V-7 is a high-performance 4-channel TVS diode array designed to protect four high-speed I/O lines and one VCC rail. It is assembled in a compact SOT-563 surface mount package. The device offers a typical capacitance of 0.55pF per channel, making it suitable for high-speed data interfaces such as HDMI, USB 2.0, and IEEE 1394.

 

Key electrical specifications include a minimum breakdown voltage of 6V, a typical clamping voltage of 8.5V, and a maximum peak pulse current of 4.7A (8/20µs). The ESD protection meets IEC 61000-4-2 standards with ±16kV contact and ±19kV air discharge on I/O to VSS, and ±30kV on VCC to VSS. The device operates over a temperature range of -55°C to 150°C with a typical power dissipation of 380mW and a junction-to-ambient thermal resistance of 327°C/W.

 

This TVS array is fully RoHS compliant, lead-free, and halogen-free. It is supplied in tape and reel packaging with 3000 units per reel. Common applications include laptop computers, flat panel displays, video graphics cards, and SIM ports.
