STMicroelectronics HSP062-2M6

Overview

HSP062-2M6 from STMicroelectronics is a 2-channel rail-to-rail ESD protection array designed for high-speed differential interfaces including HDMI 1.3/1.4, DisplayPort, and USB 3.0. It delivers 0.6 pF typical input-to-ground capacitance, 4.6 GHz -3 dB bandwidth, and clamps to 18 V at 30 A (IEC 61000-4-2 +8 kV contact), preserving signal integrity in sub-micron IC interconnects.

For engineers reviewing the HSP062-2M6 datasheet, HSP062-2M6 pinout, HSP062-2M6 application, or HSP062-2M6 equivalent, key selection criteria include ultralow capacitance variation (≤0.17 pF), junction temperature range (-40 °C to +150 °C), ESD robustness per IEC 61000-4-2 level 4, and µQFN-6L footprint compatibility with high-density PCB layouts.

Technical Context

The HSP062-2M6 implements a symmetric rail-to-rail diode architecture across two independent channels, enabling bidirectional ESD clamping without DC path distortion. Its low capacitance variation (0.09–0.17 pF) over 200–3000 MHz ensures minimal skew between differential pairs.

Designed for 5 Gbps data rates, it maintains signal fidelity via 4.6 GHz bandwidth and exhibits <100 nA leakage at 3 V and 25 °C. The device meets MIL-STD-883G Class 3B (8 kV) and IEC 61000-4-2 level 4 (±15 kV air / ±8 kV contact) requirements.

FAQ

What is the maximum data rate supported by the HSP062-2M6?

The HSP062-2M6 supports data rates up to 5 Gbps, validated via HDMI 3.4 Gbps eye diagram testing and S21 attenuation measurements showing -3 dB at 4.6 GHz. Its 0.6 pF capacitance and rail-to-rail architecture ensure minimal insertion loss and phase skew across full differential lanes used in USB 3.0 and DisplayPort 1.2.

Can the HSP062-2M6 protect both positive and negative ESD transients?

Yes. Its rail-to-rail diode architecture provides symmetrical clamping to both VBUS and GND rails, enabling bidirectional protection against ±8 kV contact and ±15 kV air discharge per IEC 61000-4-2 level 4. This eliminates need for external biasing and ensures equal clamping response for positive and negative transients on differential lines.

Is the µQFN-6L package compatible with standard reflow soldering processes?

Yes. The HSP062-2M6 µQFN-6L package is qualified for lead-free reflow per JEDEC J-STD-020, with peak temperature up to 260 °C. ST recommends a ramp rate ≤2 °C/s, 180–220 °C preheat, 90-second liquidus time, and cooling rate ≤3 °C/s - all achievable using standard convection reflow ovens with controlled convection airflow.

How does the HSP062-2M6 differ from single-channel ESD protectors in differential applications?

Unlike single-channel devices requiring two separate placements, the HSP062-2M6 integrates matched capacitance and timing characteristics across both channels in one µQFN-6L package. This guarantees ≤0.17 pF capacitance variation between I/O1 and I/O2, preventing differential skew that would degrade eye opening in HDMI or DP links - a critical advantage unattainable with discrete solutions.
