TDS5311P delivers near-constant clamping voltage across current and temperature where conventional TVS diodes fall short
CAMARILLO, Calif.–(BUSINESS WIRE)–Semtech Corporation (Nasdaq: SMTC), a leading provider of high-performance semiconductors powering data center networking, Internet of Things (IoT) connectivity and cellular infrastructure solutions, today announced the TDS5311P, the industry’s first circuit protection device to deliver near-constant clamping voltage for USB Power Delivery (PD) Extended Power Range (EPR) applications at 48 V. The latest addition to its SurgeSwitch® family, the TDS5311P protects power buses (VBus) operating at up to 53 V, purpose-built for the growing class of USB PD EPR systems operating at 48 V across industrial equipment, rugged mobility devices and high-performance portable systems.
As USB PD EPR adoption extends into industrial equipment, rugged mobility devices and high-performance portable systems, designers face a protection gap: conventional TVS diodes clamp inconsistently, with clamping voltage shifting across current levels and temperature ranges. The TDS5311P, built on SurgeSwitch’s surge-rated FET architecture, maintains a nearly constant clamping voltage from the first microsecond of a surge event through maximum rated current, across the full -40°C to +125°C industrial temperature range.
“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 TDS5311P handles 1512 W peak pulse power, 24 A peak pulse current and meets the IEC 61000-4-5 industrial surge standard, all from a 2.0 x 2.0 mm DFN-6 (Dual Flat No-lead) package.
The TDS5311P is available now. Learn more at https://www.semtech.com/products/circuit-protection/tvs-diodes/tds5311p.
