Description

Product Overview

The PESD5V0S1UA from Nexperia (formerly NXP) is a unidirectional Transient Voltage Suppression (TVS) diode designed for ESD protection of a single signal line. Packaged in a compact SOD-323 (SC-76) surface-mount package, it provides 5V reverse standoff voltage, 19V clamping voltage, and up to 890W peak pulse power. The device meets IEC 61000-4-2 Level 4 (30kV ESD contact discharge) and IEC 61000-4-5 surge (47A, 8/20µs), and is AEC-Q101 qualified for automotive applications.

Qualification AEC-Q101

Features

  • Unidirectional ESD protection for one signal line
  • High ESD immunity: 30kV contact discharge (IEC 61000-4-2 Level 4)
  • Low clamping voltage: 19V at 47A surge
  • Low leakage current: 300nA maximum
  • AEC-Q101 qualified for automotive electronics
  • Compact SOD-323 package (1.7 x 1.25 x 0.95mm)

Applications

  • ESD protection for USB, RS-485, CAN bus data lines
  • Cellular handset and portable electronics I/O protection
  • Audio and video equipment input protection
  • Automotive sensor and communication interfaces
  • Industrial control system signal line protection

The PESD5V0S1UA from Nexperia is a unidirectional ESD protection diode in a SOD-323 surface-mount package, engineered to safeguard a single signal line from electrostatic discharge and transient overvoltage events. With a 5.0V reverse standoff voltage and 19V clamping voltage at 47A peak pulse current, it is ideal for protecting 5V logic and communication interfaces. The device absorbs up to 890W peak pulse power (8/20µs waveform) and withstands 30kV contact ESD per IEC 61000-4-2 Level 4. The low 300nA leakage current minimizes power consumption in battery-operated devices. AEC-Q101 qualification makes it suitable for automotive sensor and infotainment system protection.

1. Normal Operation: Under normal signal conditions (0 to 5V), the TVS diode operates in reverse bias below the breakdown voltage. The 300nA leakage current is negligible, and the 480pF capacitance has minimal impact on low-speed signals.
2. ESD Event Clamping: When an ESD strike occurs, the voltage on the protected line rapidly rises. Once the voltage exceeds the breakdown voltage (~6V), the avalanche diode conducts heavily, diverting the ESD current to ground and clamping the voltage to 19V maximum.
3. Surge Protection: For IEC 61000-4-5 surge events (8/20µs waveform), the device absorbs up to 890W peak power by conducting the surge current while maintaining the clamping voltage, protecting downstream circuitry.
4. Unidirectional Operation: The diode clamps positive transients through avalanche breakdown and negative transients through forward conduction, providing bidirectional protection for signals referenced to ground.

Pin Name Function
1 Cathode Connect to protected signal line (positive node)
2 Anode Connect to ground (GND)
  • USB 2.0 data line (D+/D-) ESD protection in consumer electronics
  • CAN bus and LIN bus transceiver pin protection in automotive modules
  • RS-485 communication port surge protection in industrial systems
  • Touchscreen controller I/O pin protection in mobile devices
  • Audio codec input/output line ESD protection
