NXP Semiconductors PRTR5V0U1T,215

Overview

PRTR5V0U1T from Nexperia is an ultra-low-capacitance (1 pF), single-channel rail-to-rail ESD protection diode in SOT23 package, designed to safeguard high-speed data lines-including USB 2.0 and HDMI interfaces-against IEC 61000-4-2 level 4 ESD transients (±8 kV contact). It features a reverse standoff voltage of 5.5 V, clamping voltage optimized by an integrated auxiliary ESD diode, and operates across −40 °C to +85 °C ambient.

For engineers reviewing the PRTR5V0U1T datasheet, PRTR5V0U1T pinout, PRTR5V0U1T application, or PRTR5V0U1T equivalent, this device is selected for signal integrity-critical ESD protection where sub-1.5 pF capacitance, low reverse leakage (<100 nA at 3 V), and supply-independent clamping are mandatory design requirements.

Technical Context

The PRTR5V0U1T implements a dual-diode rail-to-rail architecture with one I/O-to-VCC diode and one I/O-to-GND diode, plus an additional dedicated ESD diode between VCC and GND to prevent supply-line charging during transients. This ensures functional protection even when VCC is unpowered or floating.

Its 1 pF I/O-to-ground capacitance is measured at 1 MHz and 0 V bias, enabling minimal signal distortion on 480 Mbps USB 2.0 differential pairs and HDMI TMDS channels. Clamping performance is validated per IEC 61000-4-2 with <10 ns response and sub-12 V peak clamped voltage under ±1 kV ESD pulses.

FAQ

What is the maximum I/O-to-ground capacitance specification for PRTR5V0U1T?

The PRTR5V0U1T has a maximum I/O-to-ground capacitance of 1.5 pF, measured at 1 MHz and 0 V bias. This value is confirmed in Table 1 and Table 8 of the official datasheet. The typical value is 1 pF, making PRTR5V0U1T suitable for preserving signal integrity on USB 2.0 and HDMI 1.3 data lines without introducing measurable jitter or rise-time degradation.

Does PRTR5V0U1T require an active VCC supply to provide ESD protection?

Yes and no: PRTR5V0U1T uses VCC as a reference for its primary rail-to-rail clamping path, but its integrated VCC–GND ESD diode enables partial protection even when VCC is unpowered or floating. This dual-path architecture ensures clamping remains functional during brown-out or hot-plug scenarios, a key differentiator versus basic bidirectional diodes like PESD5V0S1BA.

What ESD standards does PRTR5V0U1T comply with, and at what levels?

PRTR5V0U1T complies with IEC 61000-4-2 level 4 for contact discharge (±8 kV) and meets MIL-STD-883 human body model (±10 kV). These ratings are explicitly stated in Table 6 and Table 7 of the datasheet. Compliance is verified using the test setup shown in Figure 3, with clamped waveforms demonstrating sub-12 V peak voltage under ±1 kV ESD pulses.

Can PRTR5V0U1T be used to protect differential signal pairs such as USB D+/D−?

Yes - PRTR5V0U1T is designed for single-ended or differential line protection. For USB D+/D−, two PRTR5V0U1T devices are used (one per line), each placed within 3 mm of the connector. Its 1 pF capacitance ensures matched loading, preserving common-mode rejection and eye diagram integrity at 480 Mbps, as validated in application note AN10782.

What is the reverse leakage current of PRTR5V0U1T at 3 V reverse bias?

The reverse leakage current of PRTR5V0U1T is specified as <100 nA at VR = 3 V, with typical values below 1 nA. This parameter is listed in Table 8 under "IR" and ensures minimal DC loading on high-impedance signal paths such as audio jack MIC inputs or sensor interfaces, preventing baseline shift or measurement error.
