Nexperia USA Inc. PESD3V3L4BHCYL

Overview

PESD3V3L4BHCYL from Nexperia is a 4-fold bidirectional ESD protection array in a DFN1308-6 (SOT8006) package, designed to protect up to four low-speed signal lines against IEC 61000-4-2 ±20 kV contact/air discharge and IEC 61000-4-5 6 A 8/20 µs surges. It features 3.3 V reverse standoff voltage, 7.3 V typical clamping at 6 A, 0.2 Ω dynamic resistance, and 7.2 pF diode capacitance at 1 MHz.

For engineers reviewing the PESD3V3L4BHCYL datasheet, PESD3V3L4BHCYL pinout, PESD3V3L4BHCYL application, or PESD3V3L4BHCYL equivalent, this device is selected for compact, low-capacitance ESD hardening of USB 2.0, HDMI DDC, I²C, and GPIO interfaces in portable consumer electronics where board space and signal integrity are critical.

Technical Context

This device implements four independent bidirectional TVS diodes sharing two common cathode terminals (pins 2 and 5), enabling symmetrical clamping for AC-coupled or ground-referenced bidirectional signals. Its TLP-measured 0.2 Ω dynamic resistance ensures minimal voltage overshoot during fast transients.

The 3.3 V VRWM rating targets 3.3 V logic systems, while its 6.7 V trigger voltage and 7.3 V clamping at 6 A provide tight transient suppression without compromising normal signal swing. The 7.2 pF capacitance supports data rates up to 480 Mbps on USB 2.0 lines when placed per layout guidelines.

FAQ

What is the maximum recommended trace length between PESD3V3L4BHCYL and the protected connector?

Per Nexperia application guidance, the trace from the device cathode to system ground must be ≤3 mm, and the trace from anode (protected line) to connector must be ≤5 mm. Longer paths increase inductance, degrading clamping performance above 1 GHz and risking overshoot beyond VCL spec. Layout must use solid ground plane beneath the device.

Can PESD3V3L4BHCYL protect AC-coupled differential signals like USB 2.0 without DC bias?

Yes. Its bidirectional structure operates symmetrically around 0 V, making it suitable for AC-coupled lines. The 3.3 V VRWM ensures no conduction during normal signal swing (±400 mV for USB 2.0), while ±20 kV ESD rating handles transients regardless of DC offset. No external biasing is required.

How does the dual-common-cathode configuration affect PCB layout versus single-common designs?

Pins 2 and 5 are electrically isolated internal cathodes-each serving two diodes. This allows separate grounding of two 2-line groups (e.g., USB D+/D− on pins 1/3 + pin 2; I²C SDA/SCL on pins 4/6 + pin 5), preventing noise coupling between unrelated signal domains and simplifying ground partitioning in mixed-signal boards.

Is PESD3V3L4BHCYL compliant with RoHS and REACH regulations?

Yes. Nexperia confirms PESD3V3L4BHCYL meets RoHS Directive 2011/65/EU (Pb-free, Cd-free, Hg-free, Cr⁶⁺-free, PBB/PBDE-free) and REACH SVHC thresholds (<0.1 wt%).
