Product details
Overview
PESD3USB3SZ from Nexperia is a triple-channel ESD protection diode array designed for high-speed differential data lines including USB 3.1/3.2, HDMI 2.0, and MIPI D-PHY interfaces. It delivers ±15 kV IEC 61000-4-2 contact ESD protection per line, features 0.45 pF typical diode capacitance at 1 MHz, supports >17 GHz f-3dB, and uses WLCSP15 (6-3-6) package with 0.8 mm pitch for minimal PCB footprint in mobile and portable applications.
For engineers reviewing the PESD3USB3SZ datasheet, PESD3USB3SZ pinout, PESD3USB3SZ application, or PESD3USB3SZ equivalent, this device is selected for ultra-low-capacitance, high-bandwidth ESD protection where signal integrity on SuperSpeed differential pairs must be preserved without impedance discontinuity or eye diagram degradation.
Technical Context
The PESD3USB3SZ implements a snap-back clamping structure with negative dynamic resistance, reducing clamping voltage during ESD transients to protect downstream SoCs. Its TrEOS process enables robust system-level ESD immunity while maintaining low insertion loss (<–3 dB up to 17 GHz) and near-ideal differential impedance matching (Zdif ≈ 90 Ω).
Each of its three independent channels includes matched input/output terminals with dedicated ground bumps (B1–B3), enabling isolated grounding for noise suppression across differential pairs. The device operates over –40 °C to +125 °C ambient and supports 5 V DC bias with <100 nA reverse leakage per line at 5 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4S012RTER | Quad-channel, 0.5 pF typical capacitance, ±12 kV ESD rating, SON-10 package | Lower ESD rating and higher capacitance; suited for USB2.0 or lower-speed interfaces only | Select when cost sensitivity outweighs need for 10 Gbps support or ±15 kV robustness |
| SZESD7371MUTAG | Triple-channel, 0.35 pF typical capacitance, ±20 kV ESD rating, X2SON-10 package | Higher ESD rating but non-footprint-compatible; requires PCB redesign and lacks WLCSP thermal performance | Select when maximum ESD margin is critical and board space allows larger package |
Compared with TPD4S012RTER and SZESD7371MUTAG, PESD3USB3SZ uniquely balances ±15 kV protection, 0.45 pF capacitance, and WLCSP15 footprint-enabling direct integration into space-constrained USB-C/HDMI 2.0 designs without sacrificing bandwidth or thermal dissipation.

FAQ
What is the maximum operating voltage for PESD3USB3SZ?
The absolute maximum input voltage is –0.5 V to +5 V per pin, with recommended DC bias limited to ≤5 V. Exceeding 5 V risks forward conduction or breakdown; the device is not rated for sustained overvoltage conditions beyond its specified limiting values.
Can PESD3USB3SZ be used for HDMI 2.0 without degrading signal integrity?
Yes-measured differential insertion loss remains below –3 dB up to 17 GHz, and eye diagram testing shows <3% degradation at 6 Gbps (HDMI 2.0). Its 0.45 pF capacitance and matched 90 Ω differential impedance ensure minimal reflection and jitter accumulation.
How does the TrEOS process improve ESD protection performance?
TrEOS employs a snap-back clamping mechanism that reduces dynamic resistance to 0.16 Ω during ESD events, lowering clamping voltage significantly compared to standard diodes. This protects sensitive SoC I/O structures by limiting peak voltage seen during ±15 kV contact discharge.
Is the WLCSP15 package compatible with standard SMT reflow profiles?
Yes-the WLCSP15 package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 and supports standard lead-free reflow profiles (peak 260 °C, 60 s above 217 °C). Stencil aperture recommendations (0.1 mm thickness, 0.40 mm paste deposit) are provided in the datasheet.
