The widespread adoption of USB Power Delivery (PD) fast-charging technology has established the USB Type-C interface as the standard interconnect across consumer electronics and industrial equipment.
However, the high-density pinout of this connector—particularly the sub-millimeter spacing between high-voltage VBUS pins and low-voltage SBU/CC pins—creates significant vulnerability to accidental short-circuit events caused by contact or contamination, delivering destructive energy directly to downstream controller integrated circuits.
Conventional TVS protection solutions have struggled to address this industry challenge. The fundamental trade-off between high standoff voltage and low clamping voltage, combined with the physical volume constraints inherent to high-surge-capacity devices, has precluded simultaneous achievement of the performance and miniaturization requirements demanded by Type-C interface applications.
JY Electronics TS1801NB: High-Performance Transient Voltage Suppressor
JY Electronics has introduced the TS1801NB, a high-performance transient voltage suppressor specifically engineered for short-circuit protection of SBU and CC pins in USB Type-C interfaces operating at 12V and 15V PD fast-charging profiles. This device achieves an optimal balance across four critical performance metrics: high standoff voltage, high surge current capability, low clamping voltage, and compact form factor—delivering comprehensive, high-reliability transient voltage protection for USB PD fast-charging equipment and power distribution networks.
Three Core Advantages, Establishing a New Benchmark in Protection
01. Dual-Mode Protection: Exceptional Surge and ESD Immunity
Peak pulse current capability of 28A (8/20 μs waveform), corresponding to 650W peak pulse power dissipation.
ESD immunity of ±30kV contact and air discharge, exceeding IEC 61000-4-2 Level 4 requirements.
Individual I/O pins withstand >10,000 contact discharge cycles at ±30kV, significantly exceeding industry-standard device lifetimes.
02. Ultra-Low Clamping Voltage: Superior Protection for Sensitive Integrated Circuits
The TS1801NB incorporates a proprietary shallow snapback architecture with near-zero dynamic on-resistance. Dynamic resistance (R_DYN) is reduced to 0.05 Ω, yielding a clamping voltage of only 24.5V at 28A surge current—a reduction exceeding 30% versus competitive offerings.
03. Miniaturized Footprint: Optimized for Slim Form Factor Trends
Packaged in DFN1006-2L with body dimensions of 1.0 mm × 0.6 mm × 0.5 mm.
Leadless construction minimizes parasitic inductance and capacitance, compatible with high-density printed circuit board layouts.
