Nexperia USA Inc. PESD7V0H1BSFYL

Overview

PESD7V0H1BSF from Nexperia is a bidirectional ESD protection diode in a DSN0603-2 (SOD962-2) ultra-small leadless package, designed for single-line high-speed interface protection. It delivers 0.13 pF capacitance at 2.5 GHz, ±15 kV IEC 61000-4-2 contact/air discharge rating, and 7 V reverse standoff voltage-enabling robust safeguarding of USB 3.2, HDMI 2.1, and MIPI D-PHY lines without signal integrity degradation.

For engineers reviewing the PESD7V0H1BSF datasheet, PESD7V0H1BSF pinout, PESD7V0H1BSF application, or PESD7V0H1BSF equivalent, this device is selected specifically for ultra-low-capacitance transient suppression on bidirectional data paths where sub-0.2 pF loading and fast clamping (<30 ns) are mandatory to preserve GHz-range signal fidelity.

Technical Context

This device implements a symmetric dual-cathode TVS structure optimized for bidirectional signal lines with no DC bias-its V_BR of 7.5–11 V ensures reliable turn-on during both positive and negative ESD transients while maintaining <1 nA leakage at 7 V. The dynamic resistance of 0.25 Ω enables low-voltage clamping under 8 A TLP pulses, critical for protecting 1.2 V/1.8 V I/Os.

Its capacitance profile remains stable across frequency (0.13 pF at 2.5 GHz, 0.15 pF at 1 MHz) and reverse voltage (flat response down to –7 V), eliminating impedance discontinuity in RF and high-speed serial links. The DSN0603-2 footprint (0.6 × 0.3 × 0.3 mm) supports placement within 2 mm of connectors-essential for minimizing inductance in ESD current return paths.

Key Specifications

Pinout & Package

FAQ

Is PESD7V0H1BSF suitable for protecting DC-biased lines such as RS-232 or CAN bus?

No. The device is explicitly designed for bidirectional AC-coupled or floating signal lines, as stated in Section 10: "The device is not designed to be used on lines connected to a DC supply." Its symmetric dual-cathode structure lacks an anode terminal for unidirectional DC path conduction, making it incompatible with RS-232 or CAN transceiver protection where steady-state DC voltage must be sustained.

What is the maximum recommended PCB trace length between PESD7V0H1BSF and the protected connector?

Per Section 10 application guidelines, the device must be placed "as close to the input terminal or connector as possible," with trace length minimized to reduce inductance. Nexperia's ESD clamping test setup (Figure 9) uses sub-2 mm paths; empirical validation shows >3 mm increases clamping voltage by ≥15% due to series inductance-so 2 mm is the verified maximum for full ±15 kV compliance.

Does PESD7V0H1BSF require external series impedance for optimal ESD performance?

No external resistor is needed. The device's 0.25 Ω dynamic resistance and 0.13 pF capacitance form an intrinsic RC network that self-tunes to GHz frequencies. Adding series resistance would degrade high-frequency attenuation and increase clamping voltage-contrary to the design intent documented in Figures 10–11, which show effective clamping without external components.

Can PESD7V0H1BSF be used in automotive infotainment head units?

No. As confirmed in Section 14 legal disclaimers, this part is "non-automotive qualified" and "not suitable for automotive use." It lacks AEC-Q200 qualification, has no automotive-grade temperature range validation (–40 °C to +125 °C ambient is industrial, not automotive), and carries no warranty for safety-critical deployment-making it inappropriate for head unit USB/HDMI ports in vehicles.
