Product details
Overview
HSP061-2N4 from STMicroelectronics is a 3 V dual-line ESD protection array in QFN-4L package, designed for high-speed differential interfaces including HDMI 1.4, DisplayPort, and USB3.0. It delivers ultra-low 0.6 pF I/O-to-GND capacitance, 6 GHz bandwidth (–3 dB), ±8 kV contact/±15 kV air IEC 61000-4-2 ESD immunity, and operates from –40 °C to +150 °C junction temperature.
For engineers reviewing the HSP061-2N4 datasheet, HSP061-2N4 pinout, HSP061-2N4 application, or HSP061-2N4 equivalent, key selection criteria include differential line capacitance variation (<0.13 pF), stand-off voltage (3 V), clamping voltage (18 V at +8 kV), flow-through routing for signal integrity, and QFN-4L footprint compatibility with high-density PCB layouts.
Technical Context
The HSP061-2N4 integrates two matched bidirectional ESD diodes in a single QFN-4L package, configured for differential pair protection without ground reference skew. Its 0.03–0.13 pF capacitance variation across 200 MHz–3 GHz ensures minimal signal skew on high-speed links up to 5 Gbps.
It uses silicon avalanche diode technology with 6 V breakdown voltage (1 mA), 3 V stand-off voltage, and 100 nA leakage at VRM - enabling low-power, rail-to-rail protection for 3.3 V and lower logic interfaces while maintaining compliance with IEC 61000-4-2 Level 4.
Key Specifications

| Bandwidth (–3 dB) | 6 GHz - supports full-rate HDMI 1.4 (3.4 Gbps) and USB3.0 (5 Gbps) without signal attenuation |
| I/O-to-GND Capacitance | 0.6 pF typ. - preserves impedance matching and minimizes insertion loss on 100 Ω differential traces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line high-speed ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2EUSB30DRYR | 0.7 pF typ. capacitance; 5.5 GHz bandwidth; 3.6 V stand-off; 2-pin configuration per channel | Designed for USB3.0 only; lacks HDMI/DP characterization data and flow-through routing optimization | Prefer when USB3.0 is sole interface and board space allows separate channel placement |
| ESD56201D05 | 0.5 pF typ.; 8 GHz bandwidth; 5 V stand-off; requires external bias network for 3 V systems | Higher stand-off limits use in 3 V rails without derating; no published HDMI/DP eye diagram validation | Select for >5 Gbps future-proofing where 3 V compatibility can be engineered via clamping adjustment |
Compared with TPD2EUSB30DRYR and ESD56201D05, the HSP061-2N4 offers verified HDMI 1.4 and DisplayPort 1.2a eye diagrams, flow-through routing for minimal trace discontinuity, and guaranteed 0.6 pF capacitance - making it optimal for production designs requiring drop-in qualification on multiple high-speed protocols.

FAQ
What is the maximum data rate supported by HSP061-2N4?
HSP061-2N4 supports up to 5 Gbps differential signaling, validated via HDMI 1.4 (3.4 Gbps) and USB3.0 eye diagrams in the official DS8881 datasheet. Its 6 GHz bandwidth and 0.6 pF capacitance ensure <1% signal attenuation at Nyquist frequency for 5 Gbps NRZ data streams.
Can HSP061-2N4 be used on 1.8 V interfaces?
Yes - its 3 V stand-off voltage provides sufficient margin above 1.8 V rails, and leakage remains ≤100 nA at VRM = 3 V. However, clamping performance at lower voltages should be verified using IEC 61000-4-2 testing at system level due to reduced headroom below breakdown threshold.
Is thermal pad connection mandatory?
Yes - the exposed thermal pad (Pin 4) must be soldered to a solid PCB ground pour. It serves as the primary ESD current return path and improves thermal dissipation during pulse events; omitting this connection degrades clamping voltage and risks device failure under repeated ±8 kV discharges.
How does HSP061-2N4 differ from HSP061-2M6?
HSP061-2N4 is a dual-line (2-channel) device in QFN-4L, while HSP061-2M6 is a quad-line (4-channel) variant in QFN-6L. Both share identical electrical specs (0.6 pF, 6 GHz, ±8 kV), but HSP061-2N4 reduces PCB area by 40% and simplifies routing for two-lane interfaces like HDMI or single-lane USB3.0.
