Space-saving TVS provides superior ESD and surge protection for high-speed I/Os

Diodes Incorporated has released its new bidirectional TVS diode, addressing market demands for a robust protection for high-speed data ports. The D3V3Z1BD2CSP is intended to provide protection from ESD strikes and surge events. The main applications for this device are the I/O ports in high-performance computing hardware, displays, smartphone handsets, laptop and tablet computers, and gaming consoles.

While many competing products must make design trade-offs, either with strong surge protection properties or low input capacitance, the device can simultaneously deliver benefits. Its ultra-low capacitance of 0.3pF (typical) provides that signal integrity is maintained by not interfering with or impeding high-speed data communication. Its high peak pulse current (10.5A typical) and low clamping voltage (5.3V) safeguards I/O ports and their sensitive electronics from transient voltages. The risk of electrical overstress damage from activities such as frequent hot swapping is avoided. Complying with the IEC61000-4-2 immunity standard, the device supplies robust ESD protection against ±20kV air and contact discharges, improving system reliability.

The device can protect I/O interfaces, such as USB Type-C, DisplayPort, HDMI, and SD-Card, carrying high-speed data rates up to 20Gbps. Its wide operating temperature range, from -55C to +150C, ensures continued protection even in challenging application environments.

The TVS from Diodes is supplied in an extremely compact DSN0603 wafer-level chip-scale package that measures only 0.6mm x 0.3mm x 0.3mm.
