Semtech launches TDS5311P circuit protection device for USB-PD systems

Semtech Corporation (NASDAQ: SMTC) announced the release of the TDS5311P, a circuit protection device designed for USB Power Delivery Extended Power Range applications operating at 48 volts.

The TDS5311P protects power buses operating at up to 53 volts and maintains consistent clamping voltage across current levels and temperature ranges from -40°C to +125°C. The device addresses protection challenges in industrial equipment, rugged mobility devices and high-performance portable systems using USB PD EPR technology.

The component handles 1,512 watts peak pulse power and 24 amperes peak pulse current while meeting the IEC 61000-4-5 industrial surge standard. It comes in a 2.0 x 2.0 mm DFN-6 package.

"USB Power Delivery Extended Power Range is bringing 48 V into application environments that demand industrial-grade reliability," said Tamir Reshef, vice president of product marketing and applications, analog mixed signal and wireless products group at Semtech. "The TDS5311P gives designers the consistent protection behavior those systems require, in a package small enough to fit the space constraints of the devices they're building."

The device uses Semtech's SurgeSwitch surge-rated FET architecture, which the company states provides more consistent performance compared to conventional TVS diodes that experience clamping voltage variations across different operating conditions.

The TDS5311P is currently available, according to the company's announcement.
