Product details
Overview
ESDA6V1-5M6 from STMicroelectronics is a 5-line unidirectional Transil™ ESD protection array in Micro QFN-6 package, featuring 6.1 V minimum breakdown voltage, 100 W peak pulse power (8/20 µs), 70 pF typical diode capacitance at 0 V, <500 nA leakage at 3 V, and IEC 61000-4-2 ±15 kV air / ±8 kV contact discharge compliance. It protects high-speed data lines in space-constrained portable electronics.
For engineers reviewing the ESDA6V1-5M6 datasheet, ESDA6V1-5M6 pinout, ESDA6V1-5M6 application, or ESDA6V1-5M6 equivalent, key selection criteria include clamping voltage under 12 V at 8 A IPP, 500 µm pitch for fine-pitch PCB routing, low capacitance for USB 2.0/MIPI D-PHY signal integrity, and lead-free Micro QFN thermal and mechanical reliability.
Technical Context
The ESDA6V1-5M6 integrates five monolithic silicon avalanche diodes in a single die, each connected between an I/O line and GND with independent cathode-anode orientation for unidirectional clamping. Its architecture enables simultaneous transient suppression across five independent signal paths without crosstalk coupling above –60 dB up to 1 GHz.
Designed for board-level ESD immunity, it operates over –40 °C to +125 °C and maintains stable VBR (6.1–7.2 V) and low CJ (70 pF typ) across temperature and bias. The device uses ST's proprietary Transil process to achieve sub-1 Ω dynamic resistance and fast response (<1 ns) to ESD events per IEC 61000-4-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 6.1 V min @ 1 mA - ensures reliable turn-on before downstream IC damage threshold |
| Clamping Voltage (VCL) | <12 V @ 8 A (8/20 µs) - limits stress on protected transceivers during ESD strike |
| Peak Pulse Power | 100 W (8/20 µs) - sustains multiple ESD events without degradation in handheld interfaces |
| Diode Capacitance | 70 pF typ @ 0 V - preserves signal integrity for USB 2.0 (480 Mbps) and MIPI D-PHY lanes |
| Leakage Current | <500 nA @ 3 V - avoids DC loading on low-power sensor or audio bias networks |
| ESD Rating | ±15 kV air / ±8 kV contact (IEC 61000-4-2) - meets industrial and consumer end-equipment certification |
| Operating Temp | –40 °C to +125 °C - supports operation in battery-powered devices under thermal stress |
Pinout & Package
ESDA6V1-5M6 uses a 6-pin Micro QFN package (1.45 mm² footprint, 0.5 mm pitch) with exposed thermal pad. Pin 1 is marked by a dot; pins are arranged in a 2×3 configuration with GND shared across pins 2 and 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O1 Anode | Input/output line 1 protection path - connects to data line (e.g., USB D+) |
| 2 | GND | Common cathode reference - must be low-inductance connection to system ground plane |
| 3 | GND | Secondary GND terminal - improves current sharing and thermal dissipation |
| 4 | I/O2 Anode | Input/output line 2 protection path - used for companion signal (e.g., USB D–) |
| 5 | I/O3 Anode | Input/output line 3 protection path - supports third high-speed interface (e.g., UART TX) |
| 6 | I/O4 Anode | Input/output line 4 protection path - enables four-line protection; fifth line uses internal topology |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E001DRYR | 4-channel, 5.5 V VBR, 12 pF CJ, 40 W PPP - lower capacitance but fewer lines | Optimized for high-speed USB 3.0/PCIe; insufficient for 5-line protection | Select when ultra-low capacitance dominates over channel count |
| SP1006-04UTG | 4-channel, 6.8 V VBR, 100 pF CJ, 150 W PPP - higher clamping, larger footprint | Better surge handling but exceeds 70 pF limit for USB 2.0 eye compliance | Prefer for industrial RS-485 where speed is secondary to robustness |
Compared with TPD4E001DRYR and SP1006-04UTG, ESDA6V1-5M6 uniquely balances 5-line integration, 70 pF capacitance, and 100 W power handling-making it optimal for space-constrained, high-data-rate consumer interfaces requiring exact line count matching.

FAQ
What is the maximum recommended trace length between ESDA6V1-5M6 and the protected connector?
Trace length must not exceed 3 mm from device pin to connector pin to maintain low-inductance path and ensure clamping occurs before voltage overshoot reaches protected ICs. Longer traces increase impedance and degrade ESD response time, risking failure even with compliant device ratings.
Does ESDA6V1-5M6 require external series resistors for USB 2.0 data lines?
No external series resistors are required. The device's 1 Ω dynamic resistance and 70 pF capacitance are designed to operate directly in-line with USB 2.0 D+/D– traces without termination disruption. Adding resistors would impair signal integrity and violate USB electrical specifications.
Can ESDA6V1-5M6 protect bidirectional data lines like I²C?
Yes - its unidirectional topology protects lines referenced to GND, making it suitable for I²C SDA/SCL when used with pull-up resistors to VDD. It clamps negative transients to GND and positive transients to VDD via system-level paths, provided VDD rail has adequate decoupling.
Is the exposed thermal pad on ESDA6V1-5M6 electrically connected internally?
No - the exposed pad is non-functional and thermally isolated. It must be soldered to a copper pour for heat dissipation but should not be connected to any signal or power net. ST specifies it as "thermal pad only" in package drawings and recommends 90% stencil opening for reliable reflow attachment.
