SLLS266H –FEBRUARY 1997–REVISED MAY 2015

SNx52x0 USB Port Transient Suppressors

1 Features 3 Description

The SN65220 device is a dual, and the SN65240 and

• Design to Protect Submicron 3-V or 5-V

SN75240 devices are quadruple, unidirectional

Circuits from Noise Transients

transient voltage suppressors (TVS). These devices

• Port ESD Protection Capability Exceeds:

provide electrical noise transient protection to

– 15-kV Human Body Model

Universal Serial Bus (USB) low and full-speed ports.

The input capacitance of 35 pF makes it unsuitable

– 2-kV Machine Model

for high-speed USB 2.0 applications.

• Available in a WCSP Chip-Scale Package

Any cabled I/O can be subjected to electrical noise

• Stand-Off Voltage: 6 V (Min)

transients from various sources. These noise

• Low Current Leakage: 1-µA Max at 6 V

transients can cause damage to the USB transceiver

• Low Capacitance: 35-pF (Typ)

and/or the USB ASIC if they are of sufficient

magnitude and duration.

2 Applications

The ESD performance of the SN65220, SN65240,

and SN75240 devices is measured at the system

• USB Full-Speed Host, HUB, or Peripheral

level, according to IEC61000-4-2. However, system

• Ports

design impacts the results of these tests. To

accomplish a high compliance level requires careful

board design and layout techniques.

Figure 4 shows the equivalent circuit diagram of a single TVS diode. For positive transient voltages, only the Q1 transistor determines the switching characteristic.

SN65220, SN65240, SN75240 www.ti.com SLLS266H – FEBRUARY 1997 – REVISED MAY 2015 11.2.2 Detailed Design Procedure To effectively protect USB transceivers, use TVS diodes with breakdown voltages close to 6 V, such as the SN65220, SN65240, or SN75220 devices. Because of the TVS junction capacitance of 35 pF, apply these TVS diodes only to USB transceivers with fullspeed capability that is 12 Mbps maximum.

SN65220, SN65240, SN75240 SLLS266H – FEBRUARY 1997 – REVISED MAY 2015 www.ti.com 12 Power Supply Recommendations Unlike other semiconductor components that require a supply voltage to operate, the SN65220, SN65240, and SN75240 transient suppressors are combinations of multiple p-n diodes, activated by transient voltages. Therefore, these transient suppressors do not require external voltage supplies. 13 Layout 13.
