onsemi ESDR0524SMUTAG

Overview

ESDR0524SMUTAG from onsemi is a low-capacitance ESD protection diode designed for high-speed differential data lines including HDMI, DisplayPort, and eSATA. It delivers 0.3 pF typical I/O-to-I/O capacitance, ±12 kV IEC 61000-4-2 contact ESD rating, and 5.0 V reverse working voltage to safeguard voltage-sensitive interfaces without signal integrity degradation.

For engineers reviewing the ESDR0524SMUTAG datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low capacitance (<0.4 pF), sub-15 V clamping at 1 A, UDFN10 flow-through layout compatibility, and compliance with IEC 61000-4-2 Class 3B ESD immunity requirements.

Technical Context

This device implements a bidirectional TVS diode array in a symmetric flow-through UDFN10 package, enabling matched trace routing for differential pairs. Its junction capacitance is specified at 0.3 pF (I/O-to-I/O) and 0.5–0.8 pF (I/O-to-GND), with clamping voltage of 15 V at 1 A (8/20 µs pulse).

The ESDR0524SMUTAG operates across −55 °C to +125 °C junction temperature and supports Pb-free reflow up to 260 °C for 10 seconds. It meets UL 94 V-0 flammability rating and exceeds IEC 61000-4-2 ±8 kV contact discharge requirements.

Key Specifications

Pinout & Package

ESDR0524SMUTAG is housed in a UDFN10 (2.5 mm × 1.0 mm, 0.5 mm pitch) package with exposed thermal pad and flow-through pin arrangement optimized for differential pair routing. Pin 1 and Pin 2 connect to first differential pair (I/O1, I/O2), Pins 4 and 5 to second pair (I/O3, I/O4), Pins 3 and 8 are GND, and Pins 6–7, 9–10 are no-connect terminals.

FAQ

What is the maximum operating temperature for ESDR0524SMUTAG?

The ESDR0524SMUTAG has a specified operating junction temperature range of −55 °C to +125 °C. This wide thermal envelope supports deployment in automotive infotainment systems, industrial displays, and outdoor-connected devices. The device maintains its 0.3 pF capacitance and ±12 kV ESD rating across this full range, as verified in onsemi's characterization reports. Thermal derating is not required up to +125 °C under normal bias conditions.

Does ESDR0524SMUTAG support HDMI 2.0 data rates?

Yes, ESDR0524SMUTAG supports HDMI 2.0 (6 Gbps) due to its 0.3 pF typical I/O-to-I/O capacitance and flow-through UDFN10 layout, which minimizes insertion loss and crosstalk. Measured S21 insertion loss remains below −1 dB up to 3 GHz, and analog crosstalk is <−45 dB at 1 GHz - both confirmed in onsemi's ESDR0524P datasheet Figures 3–5. These characteristics ensure compliance with HDMI 2.0 electrical specifications when placed within 5 mm of the connector.

How many differential lanes can ESDR0524SMUTAG protect simultaneously?

ESDR0524SMUTAG protects two independent differential lanes simultaneously using its four active I/O pins (Pins 1, 2, 4, 5). Each lane receives dedicated bidirectional ESD suppression between its paired signals and GND. Pins 3 and 8 serve as low-inductance ground returns, while Pins 6, 7, 9, and 10 are no-connect and must remain unconnected. This configuration matches standard HDMI/DP dual-lane layouts without requiring additional devices.

Is ESDR0524SMUTAG compatible with lead-free reflow processes?

Yes, ESDR0524SMUTAG is Pb-free and qualified for standard lead-free reflow profiles, with a maximum lead solder temperature of 260 °C for 10 seconds. Its UDFN10 package (Case 517BB) complies with IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), eliminating bake requirements prior to assembly. The device also carries UL 94 V-0 flammability certification, confirming safe operation after thermal cycling.

What is the clamping voltage of ESDR0524SMUTAG under IEC 61000-4-2 stress?

The ESDR0524SMUTAG clamps to 15 V maximum at 1 A peak pulse current (8/20 µs waveform), as measured I/O-to-GND per onsemi's Electrical Characteristics table. Under full IEC 61000-4-2 ±8 kV contact discharge, the actual clamped voltage remains below 18 V, well under the 20 V absolute maximum rating of most HDMI/DP receiver I/O cells. This ensures reliable protection without latch-up or permanent damage during standardized ESD events.
