The TSM24B is a part of TI’s surge protection device family. The TSM24B robustly shunts up to 20 A of IEC 61000-4-5 fault current to protect systems from high power transients or lightning strikes. The TSM24B is rated to dissipate ESD strikes beyond the maximum level specified in the IEC 61000-4-2 international standard (±30-kV contact, ±30-kV air-gap). The TSM24B clamps during a surge event, keeping system exposure below 33 V (typical) at I PP = 20 A. Additionally, the TSM24B is available in a small leaded SOT-23 (DBZ) package, which is reduced in size by approximately 50 percent compared to the industry standard SMA package. The device is designed to have a minimal effect on the protected line due to extremely low device leakage. The TSM24B is a part of TI’s surge protection device family.

The TSM24CA-Q1 is a low-capacitance TVS diode and is part of TI’s surge protection device family. The TSM24CA-Q1 robustly shunts up to 30 A of IEC 61000-4-5 (8/20 µs) fault current to protect systems from high power transients or lightning strikes. The device offers a solution to the common industrial signal line EMC requirement to survive up to 1 kV IEC 61000-4-5 open circuit voltage coupled through a 42 Ω impedance, clamping that surge at 40 V (I PP = 24 A). The TSM24CA-Q1 also has a very low line capacitance of 12 pF which allows it to protect common automotive communication networks like CAN from surges in EV charging applications.

The TSU5611 is designed to interface the cellular phone UART, USB, and audio chips with external peripherals via a micro-USB connector. The switch features impedance detection for identification of various accessories that are attached through DP and DM of the micro-USB port. When an accessory is plugged into the micro-USB port, the switch uses a detection mechanism to identify the accessory (see the State Machine for details). It will then switch to the appropriate channel–data, audio, or UART. The TSU5611 has an I2C interface for communication with the cellular phone baseband or applications processor. An interrupt is generated when anything plugged into the micro-USB is detected. Another interrupt is generated when the device is unplugged.
