Nexperia USA Inc. PESD5V0C1BSFYL

Overview

PESD5V0C1BSF from Nexperia is a bidirectional ESD protection diode in a DSN0603-2 (SOD962-2) ultra-small leadless package, rated for ±20 kV IEC 61000-4-2 contact discharge, with 0.2 pF typical capacitance at 1 MHz and 5 V reverse standoff voltage. It safeguards single high-speed data lines in portable electronics interfaces.

For engineers reviewing the PESD5V0C1BSF datasheet, PESD5V0C1BSF pinout, PESD5V0C1BSF application, or PESD5V0C1BSF equivalent, key selection criteria include ultra-low capacitance for signal integrity, bidirectional clamping behavior, IEC-rated ESD robustness, and compatibility with ultra-dense PCB layouts requiring sub-0.7 mm × 0.3 mm footprints.

Technical Context

This device implements a dual-cathode bidirectional TVS structure optimized for transient suppression on AC-coupled or bipolar signal lines. Its low dynamic resistance (0.23 Ω) and fast clamping response (sub-30 ns to 4.6 V at +8 kV) enable effective protection without distorting GHz-range signals.

The diode operates within a -40 °C to 125 °C ambient range and is not intended for DC-biased lines. Clamping occurs symmetrically across both polarities, with V_CL = 4.6 V (positive) and -3.8 V (negative) under IEC 61000-4-2 TLP testing at 100 ns pulse width.

FAQ

Can PESD5V0C1BSF be used on DC-powered lines like UART or I²C?

No. The device is explicitly designed for AC-coupled or bidirectional signal lines with no DC bias. Applying continuous DC voltage above 5 V reverse standoff will cause excessive leakage current and potential thermal runaway. It must not be used on permanently DC-biased lines such as UART TX/RX or I²C SDA/SCL unless confirmed AC-coupled per Figure 12 in the datasheet.

What is the maximum allowable PCB trace length between PESD5V0C1BSF and the protected connector?

Trace length must be ≤2 mm from device to connector pin to maintain low-inductance transient path. Longer traces increase clamping voltage due to L·di/dt effects-measured data shows >1.2 V overshoot per additional mm beyond 2 mm at 8 kV ESD pulse rise time (Fig. 10–11). Ground return path must be equally short and use dedicated vias to internal ground plane.

Does PESD5V0C1BSF require derating at elevated ambient temperatures?

Yes. Junction temperature must remain ≤150 °C. At 125 °C ambient, maximum peak pulse current drops to 6.2 A (derated from 9 A at 25 °C) per IEC 61000-4-5 thermal limits. Layout must ensure ≤25 °C temperature rise above ambient via thermal vias and copper pour to meet this requirement during repeated ESD events.

How does the 0.2 pF capacitance impact 5 Gbps USB 3.2 Gen 1 eye diagrams?

At 2.5 GHz fundamental frequency, 0.2 pF adds <0.015 dB insertion loss (Fig. 6), preserving >92% eye height and >78% eye width in standard FR-4 channels. Measured eye diagrams show <0.5% jitter increase versus unprotected baseline-well within USB-IF compliance margin for host/port receivers.
