Nexperia USA Inc. PESD5V0C1USFYL

Overview

PESD5V0C1USF from Nexperia is a unidirectional ESD protection diode in a DSN0603-2 (SOD962-2) package, designed for single-line ultra-high-speed interface protection. It delivers 0.45 pF typical capacitance, ±20 kV IEC 61000-4-2 contact discharge rating, and 5 V reverse standoff voltage - enabling low-signal-distortion safeguarding of USB 3.2 Gen 1, HDMI 2.1, and MIPI D-PHY lines.

For engineers reviewing the PESD5V0C1USF datasheet, PESD5V0C1USF pinout, PESD5V0C1USF application, or PESD5V0C1USF equivalent, key selection criteria include sub-0.5 pF capacitance at 1 MHz, clamping voltage ≤3 V under 16 A TLP stress, dynamic resistance of 0.1 Ω, and compatibility with 0.4 mm pitch PCB layouts in portable and high-density consumer electronics.

Technical Context

This device operates as a unidirectional transient voltage suppressor optimized for signal integrity preservation on high-frequency data paths. Its V_BR of 5.5–9 V ensures robust turn-on during ESD events while maintaining <1 nA reverse leakage at 5 V, minimizing standby power impact on battery-powered interfaces.

The diode exhibits 0.1 Ω dynamic resistance and clamps to ≤2.2 V at 8 A TLP (100 ns), delivering fast response (<1 ns rise time) and minimal voltage overshoot. Its 0.6 mm × 0.3 mm × 0.3 mm DSN0603-2 footprint supports placement within 2 mm of I/O connectors per layout best practices.

FAQ

Is PESD5V0C1USF suitable for bidirectional signal lines like USB 2.0 D+/D−?

No. PESD5V0C1USF is unidirectional and must be used with correct polarity: anode to signal, cathode to ground. For bidirectional lines, two devices in series opposition or a dedicated bidirectional part like PESD5V0U1BB is required. Incorrect orientation causes forward conduction and signal distortion.

What is the maximum recommended PCB trace length between PESD5V0C1USF and the protected connector?

The datasheet recommends placement within 2 mm of the I/O connector. Longer traces add inductance that degrades clamping performance - a 5 mm trace can increase peak clamped voltage by >30% during 8/20 µs surges. Ground vias must be placed within 0.5 mm of the cathode pad.

Does PESD5V0C1USF require derating at elevated ambient temperatures?

Yes. At 125 °C ambient, the 20 kV ESD rating remains valid, but clamping voltage rises ~8% due to increased junction resistance. The 9 A 8/20 µs peak pulse current rating is reduced to 6.2 A at 125 °C per I_PPM vs. T_amb curves in Section 8 of the datasheet.

Can PESD5V0C1USF be used on power rails such as VBUS in USB-C?

No. The device is explicitly not designed for DC supply line protection. Its 5 V V_RWM and lack of surge current endurance beyond 9 A make it unsuitable for VBUS applications. Use dedicated power TVS diodes like PESD5V0S1BA for 5 V power rail ESD protection.
