Nexperia USA Inc. PESD5V0H1BLL-QZ

Overview

PESD5V0H1BLL-Q from Nexperia is an ultra-low-capacitance bidirectional ESD protection diode in a DFN1006L-2 (SOD882L-1) package, designed to protect single automotive in-vehicle network lines against IEC 61000-4-2 ESD events up to 15 kV. It delivers clamping voltage ≤5 V at 8 A TLP, dynamic resistance of 0.35 Ω, and capacitance <0.25 pF at 1 MHz - enabling robust protection for USB 3.2, HDMI 2.0, and Automotive Multi-Gigabit Ethernet interfaces.

For engineers reviewing the PESD5V0H1BLL-Q datasheet, PESD5V0H1BLL-Q pinout, PESD5V0H1BLL-Q application, or PESD5V0H1BLL-Q equivalent, key selection criteria include sub-0.25 pF capacitance, deep snap-back clamping behavior, AEC-Q101 qualification, and validated 14.6 GHz -3 dB insertion loss performance in high-speed differential signaling paths.

Technical Context

This device implements a bidirectional deep snap-back clamping structure with negative dynamic resistance, enabling rapid transition into low-impedance conduction during ESD transients while maintaining ultra-low leakage (<50 nA at 5 V) in standby. Its dual-cathode configuration (K1/K2) supports symmetric protection of bidirectional data lines without polarity constraints.

The DFN1006L-2 package integrates two cathodes on a 0.65 mm pitch, 1.0 × 0.6 × 0.45 mm body optimized for minimal parasitic inductance and PCB trace length. Layout-critical design requires placement within 2 mm of the protected connector and direct grounding via shortest possible path to preserve high-frequency transient suppression efficacy.

Key Specifications

Pinout & Package

DFN1006L-2 (SOD882L-1) is a leadless, ultra-small surface-mount laminate package measuring 1.0 mm × 0.6 mm × 0.45 mm with 0.65 mm pitch and exposed cathode terminals on bottom side. The package uses a transparent top view marking "888" and features no anode connection - both terminals are cathodes for bidirectional operation.

FAQ

What is the maximum recommended PCB trace length between PESD5V0H1BLL-Q and the protected connector?

The datasheet specifies placement within 2 mm of the connector for optimal ESD suppression. Longer traces increase inductance, degrading clamping response and allowing voltage overshoot beyond the 5 V specification. Ground return path must also be minimized - use multiple vias to inner ground planes and avoid daisy-chained ground connections.

Can PESD5V0H1BLL-Q be used to protect AC-coupled differential lines?

Yes - its bidirectional symmetry and absence of DC bias dependency make it compatible with AC-coupled LVDS, HDMI, and Ethernet lines. The device operates independently of signal polarity and does not require external biasing; clamping activates only during transient overvoltage events above 6 V breakdown threshold.

Does the 0.35 Ω dynamic resistance apply to both positive and negative ESD events?

Yes - characterization data (Fig. 7 and Fig. 8) confirms symmetric dynamic resistance of 0.35 Ω for both positive and negative TLP pulses, verified across ±16 A using 100 ns square-wave injection. This ensures consistent clamping performance regardless of ESD polarity or data line swing direction.

Is solder reflow profile information available for DFN1006L-2 package?

Yes - Nexperia provides a dedicated reflow footprint (Fig. 11) specifying 0.1 mm stencil thickness, 0.7 mm solder land width, and 0.9 mm occupied area. Peak temperature must not exceed 260 °C for ≤30 seconds; preheat ramp rate ≤3 °C/s and time above 217 °C limited to 60–150 seconds per J-STD-020.
