Taiwan Semiconductor Introduces Unidirectional ESD Protection Diodes

712370

Taiwan Semiconductor has introduced the TESDH5V0U04P2Q1, an ultra-low capacitance ESD protection diode that includes two unidirectional ESD rated clamping devices to protect high-speed data interfaces. This will protect sensitive electronic components connected to data and -or transmission lines from over-stress caused by ESD (Electrostatic Discharge).

The TESDH5V0U04P2Q1 has a unique design that includes a proprietary clamping device in a small package. During transient conditions, the proprietary clamping devices prevent over-voltage on the control/data/power lines, protecting any downstream components. The TESDH5V0U04P2Q1 will provide ESD protection up to ±20kV (contact and air discharge) according to IEC61000-4-2 and withstand peak pulse current up to 4A (8/20μs) according to IEC61000-4-5.

Key Features of TESDH5V0U04P2Q1:

  • ESD Protection for 2 high-speed I/O channels
  • Provides ESD protection for each channel to
  • IEC 61000-4-2 (ESD) ±20kV (air),
  • ±20kV (contact) to IEC 61000-4-5 (Lightning) 4A (8/20us)
  • Low clamping voltage: VCL = 22.2V @ ITLP = 16A
  • Ultra-low capacitance: 0.65pF
  • Ultra-small package DFN1006-3L
  • Fast turn-on and Low clamping voltage
  • Moisture sensitivity level: level 1, per J-STD-020
  • RoHS Compliant
  • Halogen-Free according to IEC 61249-2-21

Key Applications:

  • Computers and peripherals
  • IEEE 1394 Firewire interfaces
  • PCI Express I/O
  • USB 2.0 and 3.0 interfaces equipment
  • SATA and eSATA
  • HDMI 1.3, 1.4 and 2.0
  • Portable Electronics and Notebooks
  • Industrial Interfaces i.e., RS485
