Nexperia USA Inc. PESD6V0L2UU,115

Overview

PESD6V0L2UU from Nexperia is a low-capacitance unidirectional dual ESD protection diode in SOT323 (SC-70) package, designed to safeguard two signal lines against IEC 61000-4-2 level 4 ESD events up to ±30 kV contact discharge, with 6.0 V reverse standoff voltage, 34 pF typical diode capacitance at 1 MHz, 13.5 V clamping voltage at 5.5 A surge, and AEC-Q101 qualification for automotive interfaces.

For engineers reviewing the PESD6V0L2UU datasheet, PESD6V0L2UU pinout, PESD6V0L2UU application, or PESD6V0L2UU equivalent, key selection criteria include unidirectional dual-line protection capability, ultra-low leakage (<18 nA at 4.3 V), 60 W peak pulse power per line, and compatibility with high-speed audio/video and SIM card signal paths requiring sub-20 pF capacitance.

Technical Context

This device implements a common-anode dual-diode architecture where pins 1 and 2 serve as independent cathodes and pin 3 is the shared anode, enabling simultaneous protection of two unidirectional positive-going signals referenced to ground. Its unidirectional configuration ensures minimal forward voltage drop during normal operation while providing rapid clamping response to transient overvoltage.

The diode pair meets IEC 61000-4-2 level 4 (±8 kV contact, ±15 kV air) and IEC 61000-4-5 (6.5 A surge current) standards, with differential resistance of 30 Ω at 5 mA breakdown current and thermal limits supporting operation from −55 °C to +150 °C junction temperature.

FAQ

What is the maximum recommended PCB trace length between PESD6V0L2UU and the protected connector?

Trace length should be ≤3 mm from device cathodes (pins 1 and 2) to the protected signal lines and ≤2 mm from common anode (pin 3) to the nearest low-inductance ground plane via. Longer traces increase inductance, degrading clamping response and allowing higher transient voltages to reach protected ICs during ESD events.

Can PESD6V0L2UU be used for bidirectional signal protection?

No-PESD6V0L2UU is strictly unidirectional due to its common-anode configuration. It protects only positive-going transients on two separate lines referenced to ground. For bidirectional protection (e.g., RS-485, USB D+/D− differential pairs), a dedicated bidirectional dual-diode device such as PESD5V0X2BMS is required.

Does the 30 kV ESD rating apply to both pins 1 and 2 simultaneously?

Yes-the ±30 kV IEC 61000-4-2 contact discharge rating is verified per pin relative to the common anode (pin 3) under standard test conditions. Each cathode can withstand full-rated ESD independently, enabling robust dual-line protection without interaction or derating.

What is the thermal resistance junction-to-ambient (R_θJA) for PESD6V0L2UU in standard FR-4 PCB layout?

R_θJA is 350 K/W under JEDEC JESD51-2 conditions (single-layer 1 oz copper, 1 cm² pad). With internal thermal design using 2×2 mm² copper pour connected to pin 3 and two thermal vias, R_θJA improves to ≤220 K/W-critical for sustaining repeated 60 W surge pulses without exceeding 150 °C junction temperature.
