Product details
Overview
ESDA6V1P6 from STMicroelectronics is a unidirectional 4-line ESD protection diode array in SOT666IP package, featuring 6.1 V breakdown voltage, 15 kV air/8 kV contact IEC 61000-4-2 ESD immunity, 70 pF line capacitance, and 150 W peak pulse power (8/20 µs). It protects industrial and consumer interface lines including USB, HDMI, and GPIO against electrostatic discharge.
For engineers reviewing the ESDA6V1P6 datasheet, ESDA6V1P6 pinout, ESDA6V1P6 application, or ESDA6V1P6 equivalent, key selection criteria include clamping voltage under 20 V at 1 A, junction temperature range of −40 °C to +150 °C, low leakage (<0.5 µA at 3 V), SOT666IP footprint compatibility, and compliance with UL94 V0 and J-STD-020 MSL Level 1.
Technical Context
The ESDA6V1P6 integrates four monolithic silicon avalanche diodes in a single SOT666IP package, each configured as a cathode-to-GND unidirectional clamp. Its layout supports flexible routing-GND pins may be used as signal returns to enable bidirectional protection on symmetrical lines without external components.
Designed for transient suppression per IEC 61000-4-2 Level 4, it delivers sub-20 V clamping at 1 A peak pulse current (tp = 2.5 µs), with thermal stability up to Tj = 150 °C and junction capacitance of 70 pF at 0 V, optimized for high-speed data lines below 100 Mbps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 6.1 V min / 7.2 V max - ensures reliable turn-on before damage to downstream ICs operating at 3.3 V or 5 V logic levels |
| Clamping Voltage (VCL) | ≤20 V at 1 A (2.5 µs pulse) - limits transient overvoltage seen by protected IC I/O pins |
| Junction Capacitance (Cline) | 70 pF at 0 V - compatible with USB 2.0 and low-speed serial interfaces without signal integrity degradation |
| ESD Withstand (IEC 61000-4-2) | ±15 kV air / ±8 kV contact - meets Level 4 immunity for handheld and panel-mounted equipment |
| Peak Pulse Power (PPP) | 150 W (8/20 µs) - sustains multiple ESD events without parametric shift or failure |
| Leakage Current (IR) | ≤0.5 µA at 3 V - avoids DC loading on battery-powered or high-impedance sensor inputs |
| Operating Junction Temp | −40 °C to +150 °C - supports operation in automotive under-hood or industrial motor-control environments |
Pinout & Package
SOT666IP is a 6-pin, ultra-thin, leadless surface-mount package (1.6 mm × 1.6 mm × 0.55 mm) with exposed thermal pad, matte tin plating, and IPC7531-compliant footprint. It meets J-STD-020 MSL Level 1 and JEDEC MO-252 standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| I/O1 | Anode of Channel 1 | Input/output line protected by dedicated avalanche diode to GND |
| I/O2 | Anode of Channel 2 | Independent ESD path for second signal line; shares common GND terminals |
| GND | Cathode common node | Primary ESD return path; two pins provide low-inductance grounding for multi-line clamping |
| I/O4 | Anode of Channel 4 | Fourth protected line; pin assignment enables compact PCB layout with minimal trace length |
| I/O3 | Anode of Channel 3 | Third protected line; symmetric pinout allows balanced routing for differential pairs |
Key Features
| Feature | Design Value |
|---|---|
| Monolithic 4-channel architecture | Single-die integration eliminates inter-channel timing skew and reduces board area by >40% vs discrete diodes |
| Flexible unidirectional/bidirectional configuration | GND pins can serve as signal returns, enabling symmetrical line protection without external biasing |
| Low clamping voltage at high current | VCL ≤ 20 V @ 1 A ensures safe margin below 24 V absolute maximum ratings of common interface ICs |
| High-temperature reliability | Rated for continuous operation at Tj = 150 °C - validated for reflow, aging, and long-term field use |
| Environmental compliance | UL94 V0 flammability rating and JESD22-B102 E3 solderability ensure robust manufacturing yield and safety certification |
Applications
| USB 2.0 Interface Protection | HDMI DDC Line Protection |
|---|---|
Use Scenario: Protecting USB data lines (D+, D−) and VBUS detection in portable docking stations subject to frequent plug/unplug events. IC Role / Device Role / Timing Role: Unidirectional transient voltage suppressor placed directly at connector, clamping ESD pulses before they reach USB transceiver IC. Use Value: 70 pF capacitance avoids signal rise-time degradation; 15 kV air discharge rating exceeds IEC 61000-4-2 user-simulated stress testing. | Use Scenario: Securing HDMI Display Data Channel (DDC) lines (SCL/SDA) in AV receivers exposed to handling ESD during installation or maintenance. IC Role / Device Role / Timing Role: Low-capacitance ESD clamp on 5 V-tolerant I²C bus lines, preserving clock/data integrity at 100 kHz operation. Use Value: Sub-0.5 µA leakage prevents false ACK/NACK on open-drain bus; dual GND pins reduce ground bounce during multi-pulse events. |
| Industrial GPIO Protection | Consumer Touch Panel Interface |
Use Scenario: Shielding programmable logic controller (PLC) digital input channels connected to external sensors in factory-floor environments. IC Role / Device Role / Timing Role: Four-channel ESD array protecting isolated 24 V DC input lines, with GND pins tied to system earth reference. Use Value: 150 W peak power rating withstands repeated 8 kV contact discharges; −40 °C to +150 °C range matches industrial ambient extremes. | Use Scenario: Guarding capacitive touch controller I/O lines (X/Y electrodes) in smart home displays subjected to finger-tip ESD during daily interaction. IC Role / Device Role / Timing Role: Bidirectional-capable clamp using one GND pin as signal return, enabling symmetrical protection on analog sensing lines. Use Value: 6.1 V VBR aligns with 3.3 V touch IC supply rails; 70 pF Cline maintains electrode sensitivity without recalibration drift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDA6V1-5P6 | Same VBR (6.1 V), but in SOT666 (not SOT666IP); 2.9 mg weight vs 2.5 mg; identical electrical specs | SOT666 has slightly larger footprint and different thermal pad geometry; less suitable for ultra-thin mobile designs | Select when legacy board layout uses standard SOT666 land pattern and MSL Level 1 compliance is sufficient |
| ESDA14V2BP6 | Higher VBR (14.2 V), lower Cline (25 pF), reduced PPP (50 W); designed for 12–24 V systems | Used on higher-voltage lines (e.g., RS-485, CAN FD) where 6.1 V clamping would cause false triggering | Choose for industrial buses requiring >12 V working voltage and tighter capacitance control |
Compared with ESDA6V1-5P6, ESDA6V1P6 offers improved thermal dissipation via SOT666IP's enhanced pad design; versus ESDA14V2BP6, it provides lower clamping and better compatibility with 3.3 V/5 V logic, at the cost of higher capacitance.

FAQ
What is the maximum recommended PCB trace length between ESDA6V1P6 and the protected I/O pin?
ST recommends keeping trace length ≤3 mm from ESDA6V1P6 anode pins to the protected line and ≤2 mm from GND pins to the system ground plane. Longer traces increase inductance, degrading clamping response and risking overshoot above VCL; verified performance assumes direct placement at the connector or IC package edge.
Can ESDA6V1P6 protect bidirectional data lines like I²C without external components?
Yes - by connecting one GND pin to the signal return (e.g., pull-up rail) instead of chassis ground, ESDA6V1P6 forms a back-to-back diode pair per line. This achieves symmetrical ±8 kV contact ESD protection on open-drain buses while maintaining <0.5 µA leakage at 3.3 V.
Does ESDA6V1P6 require derating at elevated ambient temperatures?
No derating is needed up to +85 °C ambient, as its 150 °C max junction temperature and 150 W pulse rating are specified at Tj = 25 °C initial. At 125 °C ambient, peak power must be limited to ~90 W per Figure 2 in DS4625, due to thermal resistance constraints of the SOT666IP package.
Is ESDA6V1P6 compliant with RoHS and REACH regulations?
Yes - ESDA6V1P6 is manufactured in ST's RoHS-compliant facilities and meets EU Directive 2011/65/EU (RoHS 2) and Regulation (EC) No. 1907/2006 (REACH), with full substance declarations available in ST's ECOPACK documentation portal.
