STMicroelectronics HDMI05-CL02F3

Overview

HDMI05-CL02F3 from STMicroelectronics is a 5-line flip-chip ESD protection device for HDMI control lines (CEC, HPD, SCL, SDA), integrating pull-up resistors for I²C (1.75 kΩ) and CEC (27 kΩ), plus a pull-down for HPD. It delivers ±15 kV air/±8 kV contact ESD protection per IEC 61000-4-2 Level 4, with line capacitance as low as 10–12 pF under operating conditions, enabling high-speed signal integrity in mobile HDMI interfaces.

For engineers reviewing the HDMI05-CL02F3 datasheet, HDMI05-CL02F3 pinout, HDMI05-CL02F3 application, or HDMI05-CL02F3 equivalent, key selection criteria include integrated resistor values (RPU = 1.75 kΩ, RPU2 = 27 kΩ, RPD = 100 kΩ), clamping voltage ≤39 V at 30 ns under ±8 kV discharge, and ultra-thin 0.4 mm pitch flip-chip package compatibility with space-constrained portable designs.

Technical Context

This monolithic IPAD™ device integrates five bidirectional ESD protection diodes with embedded passive network: two 1.75 kΩ pull-ups on SCL/SDA, one 27 kΩ pull-up on CEC, and one 100 kΩ pull-down on HPD - all co-packaged with low-capacitance (<12 pF) transient voltage suppression. No external biasing or decoupling is required.

The flip-chip wafer-level packaging minimizes parasitic inductance and capacitance, preserving signal fidelity up to 3 GHz (S21 > –5 dB), while maintaining full compliance with HDMI DDC timing constraints for hot-plug detection and CEC command transmission.

FAQ

What is the maximum recommended trace length between HDMI05-CL02F3 and the HDMI connector?

ST recommends keeping trace lengths from the device pads to the HDMI connector pins ≤3 mm for SCL, SDA, CEC, and HPD lines. Longer traces increase inductance and degrade ESD clamping performance - measured data shows clamping voltage rises >15% at 5 mm due to L·di/dt effects during ±8 kV transients.

Can HDMI05-CL02F3 be used on HDMI 2.1 control lines?

Yes - its 10–12 pF line capacitance and <39 V clamping voltage at 30 ns meet HDMI 2.1 DDC timing requirements (rise time ≤200 ns, fall time ≤200 ns at 100 kHz). However, it does not protect TMDS lanes; separate high-speed ESD arrays (e.g., HDMIULC6-4F3) must be used for data channels.

Is the 5 V pin (B3) intended for power supply or ESD protection?

The B3 terminal is the 5 V supply pin for internal resistor biasing - it must be connected to the system's clean 5 V rail. It is not an ESD protection pin; ESD current paths are exclusively between signal pins (A1/A3/B3/C3) and ground bumps (A2/B2/C2). Do not route ESD surges through this pin.

Does HDMI05-CL02F3 require external decoupling capacitors?

No - the device contains no active circuitry and draws zero quiescent current. Its monolithic structure and flip-chip construction eliminate need for bypass capacitors. ST validation testing confirms stable DDC operation without added capacitance across the 5 V pin or ground bumps.
