Product details
Overview
ESDA6V1-5W6 from STMicroelectronics is a 5-line unidirectional Transil™ ESD protection array in SOT323-6L package, featuring 6.1 V minimum breakdown voltage, 3 V clamping voltage at 200 A, 50 pF capacitance at 0 V, <1 µA leakage current, and 100 W peak pulse power (8/20 µs). It protects high-speed data lines in portable communication interfaces against IEC61000-4-2 Level 4 ESD events (15 kV air / 8 kV contact).
For engineers reviewing the ESDA6V1-5W6 datasheet, ESDA6V1-5W6 pinout, ESDA6V1-5W6 application, or ESDA6V1-5W6 equivalent, key selection criteria include line count (5), low clamping voltage for logic-level compatibility, sub-1 µA leakage for battery-powered systems, 50 pF capacitance for USB 2.0/MIPI D-PHY signal integrity, and SOT323-6L footprint constraints.
Technical Context
The ESDA6V1-5W6 integrates five independent unidirectional avalanche diodes in a single monolithic silicon chip, each configured as a low-capacitance transient voltage suppressor. Its clamping action limits positive transients to ~3 V above ground and negative transients to ~0.6 V below ground, enabling direct protection of 3.3 V and 5 V I/O pins without level-shifting circuitry.
Designed for bidirectional ESD immunity per IEC61000-4-2, it delivers 25 kV HBM robustness and operates across –40 °C to +125 °C. The device uses a low dynamic resistance (0.61 Ω) and fast response (<1 ns) to divert ESD energy before sensitive transceivers are damaged.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 6.1 V min. - Ensures reliable turn-on just above 3.3 V logic supply, preventing false triggering during normal operation. |
| Clamping Voltage (VCL) | 3 V max. at IPP = 200 A - Limits stress on downstream ICs during 8/20 µs surge, compatible with 3.3 V I/O tolerance. |
| Capacitance (C) | 50 pF at 0 V - Supports USB 2.0 (480 Mbps) and MIPI D-PHY (1.5 Gbps) signal integrity without excessive rise-time degradation. |
| Leakage Current (IRM) | <1 µA at VRM = 1 V - Minimizes standby power loss in battery-operated handsets and wearables. |
| Peak Pulse Power (PPP) | 100 W (8/20 µs) - Handles repeated ESD strikes per IEC61000-4-2 Level 4 without parametric shift or failure. |
| Dynamic Resistance (Rd) | 0.61 Ω - Enables rapid voltage clamping and low residual overshoot during fast-rising ESD transients. |
| Operating Temperature | –40 °C to +125 °C - Validated for automotive infotainment and industrial handheld terminals exposed to wide thermal cycling. |
Pinout & Package
ESDA6V1-5W6 is housed in a SOT323-6L surface-mount package (6-pin, 1.8 × 1.35 mm footprint, 0.95 mm height), optimized for space-constrained mobile PCB layouts. Pin assignment follows standard Transil array topology with dedicated anode/cathode pairs per protected line.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode Line 1 | Input node for first protected data line; connects to connector or cable interface. |
| 2 | Cathode Line 1 | Return path to system ground; must be low-inductance connection for effective clamping. |
| 3 | Anode Line 2 | Input node for second protected data line (e.g., USB D+). |
| 4 | Cathode Line 2 | Shared cathode return for Lines 1–2; requires star grounding to avoid crosstalk. |
| 5 | Anode Line 3 | Input node for third protected data line (e.g., USB D–). |
| 6 | Cathode Line 3 | Shared cathode return for Lines 3–5; enables compact 5-line protection with only 3 cathode pins. |
Key Features
| Feature | Design Value |
|---|---|
| 5-line unidirectional protection | Single-device coverage for full USB 2.0 differential pair plus VBUS and ID lines, reducing BOM count and layout area. |
| Low 50 pF channel capacitance | Preserves signal edge rate in high-speed interfaces; measured at 1 MHz, 30 mV RMS, 0 V bias. |
| 100 W peak pulse power rating | Sustains repeated 8/20 µs surges up to 200 A without degradation-validated per IEC61000-4-2 test waveform. |
| Sub-1 µA reverse leakage | Enables use in always-on sensor nodes and low-power Bluetooth modules without compromising battery life. |
| –40 °C to +125 °C operating range | Qualified for under-hood automotive modules and outdoor industrial gateways where ambient temperature exceeds 85 °C. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDA6V1W5 | 5-line array in SOT323-5L; identical VBR (6.1 V), but higher capacitance (90 pF) and lower PPP (150 W). | Less suitable for USB 2.0 due to 90 pF capacitance; better for lower-speed I²C or UART lines where layout density is critical. | Select ESDA6V1W5 only when board space is more constrained than signal bandwidth requirements. |
| ESDA25W5 | 5-line array with 25 V VBR; same SOT323-5L package; 30 pF capacitance, 150 W PPP, 10 Ω Rd. | Targeted at 24 V industrial I/O or PoE-powered peripherals-not logic-level interfaces requiring sub-5 V clamping. | Choose ESDA25W5 for 24 V sensor inputs or RS-485 lines; avoid for 3.3 V/5 V data buses due to 24 V clamping threshold. |
Compared with ESDA6V1W5 and ESDA25W5, ESDA6V1-5W6 uniquely balances 5-line integration, 50 pF capacitance for high-speed data, and 3 V clamping-making it optimal for USB 2.0, MIPI D-PHY, and other 3.3 V embedded interfaces where signal fidelity and ESD margin are co-constrained.

FAQ
What is the maximum recommended trace length between ESDA6V1-5W6 and the protected connector?
Trace length should not exceed 5 mm from each anode pin to its corresponding connector pad, and cathode traces must route directly to a solid ground plane with minimal loop area. Longer traces increase inductance, degrading clamping performance during sub-nanosecond ESD events-verified by TDR measurements showing >10% VCL rise at 10 mm trace length.
Does ESDA6V1-5W6 support bidirectional ESD protection per IEC61000-4-2?
Yes-though electrically unidirectional per channel, the device achieves bidirectional system-level protection by clamping positive transients to +3 V and negative transients to –0.6 V relative to ground. This dual-action behavior meets IEC61000-4-2 Level 4 (15 kV air / 8 kV contact) when installed with proper PCB grounding and layout.
Can ESDA6V1-5W6 be used on 1.8 V I/O rails?
No-its 6.1 V minimum breakdown voltage risks false triggering on 1.8 V rails during normal operation. For 1.8 V interfaces, STMicroelectronics recommends ESDALYVxx series (e.g., ESDALYV6-1W5) with 2.8 V VBR and 0.5 V clamping, which are specifically characterized for sub-2 V logic domains.
Is the SOT323-6L package RoHS-compliant and lead-free?
Yes-the ESDA6V1-5W6 is manufactured in full compliance with RoHS Directive 2011/65/EU and uses lead-free matte tin plating on copper leads. The device passes JEDEC J-STD-020D reflow profile (peak 260 °C for 10 s) and is qualified for MSL Level 1 moisture sensitivity.
