Product details
Overview
MEZDPD1620AS-8502 from MEZ is a surface-mount dual-channel ESD protection diode array designed for high-speed data lines including USB 2.0 and HDMI interfaces. It features 16V working voltage, 20A peak pulse current per channel, 0.85pF typical capacitance at 1MHz, and ±15kV contact ESD protection per IEC 61000-4-2.
For engineers reviewing the MEZDPD1620AS-8502 datasheet, MEZDPD1620AS-8502 pinout, MEZDPD1620AS-8502 application, or MEZDPD1620AS-8502 equivalent, key selection criteria include low clamping voltage under transient stress, sub-1pF signal-line capacitance for minimal signal integrity impact, dual-channel symmetry, and SOT-23-6 package compatibility with high-density PCB layouts.
Technical Context
This device implements a dual unidirectional TVS structure with common-anode configuration, enabling independent protection of two signal paths while sharing ground reference. Each channel delivers 16V standoff voltage and clamps to ≤24V at 20A 8/20μs pulse, meeting IEC 61000-4-2 Level 4 requirements.
The 0.85pF capacitance at 1MHz and low leakage current (<1μA at 16V) support full-speed USB 2.0 (480Mbps) and HDMI 1.4a compliance without signal degradation. The SOT-23-6 package provides thermal dissipation sufficient for repeated ESD events in portable electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 16V - Maximum continuous DC operating voltage before conduction begins. |
| Peak Pulse Current | 20A per channel - Withstands 8/20μs surge without failure, supporting robust system-level ESD immunity. |
| Capacitance | 0.85pF at 1MHz - Minimizes signal distortion on high-speed differential pairs like USB D+/D−. |
| ESD Protection Level | ±15kV contact per IEC 61000-4-2 - Meets industrial-grade electrostatic discharge immunity requirements. |
| Clamping Voltage | ≤24V at 20A - Limits voltage seen by protected ICs during transient events to safe levels. |
| Leakage Current | <1μA at 16V - Prevents DC loading of signal lines and preserves interface power budget. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode Channel A | Input terminal for first protected signal line (e.g., USB D+). |
| 2 | Cathode Common | Shared cathode connection tied to system ground for both channels. |
| 3 | Anode Channel B | Input terminal for second protected signal line (e.g., USB D−). |
| 4 | No Connect | Internally unused; must be left floating or grounded per layout guidelines. |
| 5 | No Connect | Internally unused; must be left floating or grounded per layout guidelines. |
| 6 | Exposed Pad | Thermal and electrical ground connection; soldered to PCB ground plane for optimal heat dissipation. |
Key Features
| Feature | Design Value |
|---|---|

IC Role / Device Role / Timing Role: Low-capacitance ESD shunt on differential video pairs, mounted adjacent to connector. Use Value: Enables compliance with ISO 10605 (330pF/330Ω) automotive ESD test without degrading pixel clock integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | 0.9pF capacitance, 12V working voltage, SOT-553 package (5-pin) | Single-channel, lower working voltage limits use in 3.3V-only systems | Prefer when board space is constrained and only one line requires protection. |
| SP1002-01WTG | 0.6pF capacitance, 5V working voltage, SOD-323 package | Lower voltage rating restricts use to 3.3V logic; smaller footprint but no common-cathode dual-channel layout | Select for ultra-low-capacitance needs in compact 3.3V sensor interfaces. |
Compared with TPD2E001DRYR and SP1002-01WTG, MEZDPD1620AS-8502 uniquely supports dual-channel 16V operation in SOT-23-6, enabling balanced protection of differential pairs without sacrificing clamping performance or PCB routing efficiency.

FAQ
What is the maximum operating temperature for MEZDPD1620AS-8502?
The device is rated for continuous operation from −40°C to +125°C ambient temperature. Thermal performance is validated with the exposed pad soldered to ≥100mm² copper area, ensuring reliable clamping behavior across automotive and industrial temperature ranges without derating.
Does MEZDPD1620AS-8502 support bidirectional signal lines like USB OTG?
No - it uses a dual unidirectional configuration with common cathode, optimized for fixed-direction high-speed lines such as USB 2.0 D+/D− or HDMI TMDS pairs. Bidirectional protection requires separate anode-cathode arrangements not implemented in this part.
Can Pin 4 and Pin 5 be used as additional ground connections?
No - Pins 4 and 5 are internally unconnected (NC). They must remain floating or be tied to ground only if required by PCB mechanical stability or EMI shielding; doing so does not improve electrical performance or thermal dissipation.
How does the 0.85pF capacitance affect HDMI 1.4a compliance?
At 0.85pF, the device introduces negligible impedance change on TMDS lines up to 340MHz, preserving the 100Ω differential characteristic impedance and maintaining eye opening >70% at 1.65Gbps, satisfying HDMI 1.4a electrical compliance requirements.
Is MEZDPD1620AS-8502 compliant with RoHS and REACH?
Yes - the device meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free matte tin termination and halogen-free molding compound, verified via certified material declarations from MEZ.
What is the recommended PCB layout for optimal ESD performance?
Place the device within 3mm of the protected connector, route protected traces as controlled-impedance differential pairs, connect the exposed pad to a solid ground plane with ≥4 thermal vias, and avoid stubs or right-angle bends in the signal path to minimize inductance and preserve clamping speed.
