PESD1USB30Z

PESD1USB30Z is a USB Electrostatic Discharge (ESD) protection device—specifically a diode/TVS array designed to protect USB data lines from ESD events. It typically provides two protected data-line channels (D+ and D−) with very low capacitance, so it protects high-speed USB signals (2.0/3.x) without distorting them. The device clamps fast ESD spikes to safe levels and has low leakage when unpowered. The “30Z” suffix denotes a particular variant/package of this family; exact electricals (capacitance, ESD rating, working voltage, pinout) vary by package. Common applications include USB ports on consumer electronics, PCs, hubs, and mobile devices, where it helps meet ESD standards (IEC 61000-4-2). For precise specs and pinout, consult the manufacturer’s datasheet for PESD1USB30Z.

PESD1USB30Z features (concise):
- USB port ESD protection diode array for data lines (D+ and D-)
- Ultra-low input capacitance to maintain USB signal integrity (2.0/3.0)
- Bidirectional ESD protection with low clamping voltage
- Fast response and low leakage
- High ESD robustness per IEC 61000-4-2 (without external components)
- Small, single-device solution (no external components required)
- RoHS compliant and halogen-free
- Suitable for USB interfaces with minimal PCB impact
Note: For exact electrical specs (capacitance, clamping voltages, ESD ratings, packaging), please consult the datasheet.

Pin count: 3 pins.
Function: A single-channel USB ESD protection diode array. It protects one USB data line (D+ or D−) by clamping ESD transients to the supply rails (GND and VCC).

Manufacturer: Nexperia.
What kind of company: Nexperia is a global semiconductor manufacturer (headquartered in the Netherlands) that specializes in high-volume discrete components, MOSFETs, logic ICs and interface/protection devices (including ESD/USB protection diodes like the PESD1USB30Z). It was spun out of NXP and focuses on production of standardized semiconductor building blocks for industrial, automotive and consumer markets.

Applications of PESD1USB30Z:
- USB interface protection for consumer electronics (smartphones, tablets, laptops, desktops, USB hubs, docking stations)
- USB data lines in peripherals (keyboards, mice, flash drives, cameras, external drives)
- High-speed USB ports (USB 2.0/3.0, Type-C) needing low-capacitance ESD protection
- Automotive USB ports (infotainment, diagnostics)
- Industrial/embedded systems with USB connectivity
- Wearables and portable devices requiring PCB-level USB ESD protection

PESD1USB30Z is supplied in a SOD523 (SC-70) surface-mount package — a tiny 2‑lead package for low‑capacitance ESD protection in USB applications.
