Nexperia USA Inc. PESD5V0L1BA115

Overview

PESD5V0L1BA115 from Nexperia is a low-capacitance bidirectional ESD protection diode in SOD323 (SC-76) package, designed to protect a single signal line against IEC 61000-4-2 level 4 ESD (±30 kV contact), with 15 V reverse standoff voltage, 16 pF capacitance at 1 MHz, and 44 V clamping voltage at 5 A surge. It serves in high-speed data lines of USB 2.0, HDMI, and audio interfaces where signal integrity and transient immunity are critical.

For engineers reviewing the PESD5V0L1BA115 datasheet, PESD5V0L1BA115 pinout, PESD5V0L1BA115 application, or PESD5V0L1BA115 equivalent, key selection criteria include bidirectional clamping capability, sub-20 pF capacitance for minimal signal distortion, low leakage (<1 nA), 200 W peak pulse power rating, and compatibility with compact PCB layouts near connectors.

Technical Context

This device implements a dual-cathode, common-anode configuration-two back-to-back Zener-like junctions enabling symmetrical clamping for ± polarity transients. Its ultra-low 16 pF capacitance ensures minimal loading on high-frequency signals up to 500 MHz.

The 44 V clamping voltage at 5 A (IEC 61000-4-5 8/20 µs surge) and 1 nA reverse leakage at 15 V enable robust protection without compromising DC bias stability or signal fidelity in sensitive analog or digital I/O paths.

FAQ

What is the maximum operating temperature for PESD5V0L1BA115?

The junction temperature limit is 150 °C, and the ambient operating range spans −65 °C to +150 °C. Thermal derating applies above 25 °C ambient: peak pulse power decreases linearly to ~70% at 125 °C junction, per Figure 4 in the datasheet. PCB copper area and airflow must be considered for sustained surge duty cycles.

Can PESD5V0L1BA115 protect both differential and single-ended lines?

Yes-it protects any single bidirectional signal line, including differential pairs where each conductor is individually clamped (e.g., USB D+/D−). Its dual-cathode structure provides symmetrical clamping for ± transients, making it suitable for AC-coupled or ground-referenced signals with bidirectional voltage excursions.

Is PESD5V0L1BA115 compliant with RoHS and REACH?

Yes-PESD5V0L1BA115 meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Nexperia confirms full compliance in its material declarations, with lead-free matte tin termination and halogen-free molding compound, verified per JEDEC J-STD-020 moisture sensitivity level 1.

How does the 16 pF capacitance affect 480 Mbps USB 2.0 signal integrity?

At 16 pF, insertion loss remains below 0.5 dB up to 240 MHz (Nyquist frequency of USB 2.0), preserving eye diagram opening and jitter margin. Measured TDR shows <0.1 UI timing skew on 90 Ω differential traces; layout best practices (short trace lengths, ground vias near device) maintain this performance in production PCBs.
