Product details
Overview
ESDA6V1W5 from STMicroelectronics is a 5-line unidirectional Transil™ ESD protection array in SOT323-5L package, designed for high-speed data line protection with 6.1 V min. breakdown voltage, 3 V clamping voltage at 200 A, 90 pF capacitance at 0 V, and 25 kV IEC61000-4-2 air discharge rating-used in cellular phone handset USB/UART interfaces.
For engineers reviewing the ESDA6V1W5 datasheet, ESDA6V1W5 pinout, ESDA6V1W5 application, or ESDA6V1W5 equivalent, key selection criteria include low clamping voltage under 200 A surge, sub-1 µA leakage at 3 V, 5-line integration in <4.2 mm² footprint, and compliance with IEC61000-4-2 Level 4 (15 kV air / 8 kV contact).
Technical Context
This monolithic TVS array uses silicon avalanche diode structures arranged as five independent unidirectional clamps, each referenced to ground. It operates with bidirectional transient suppression: positive transients clamp just above VCC, negative transients clamp to ~−0.7 V via forward-biased diode path.
Designed for signal integrity preservation on high-speed lines, it delivers 90 pF capacitance at 0 V bias and 6 pF at 3 V reverse bias, with dynamic resistance of 0.35 Ω enabling rapid response to ESD events up to 25 kV per IEC61000-4-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 6.1 V min. - ensures reliable triggering before logic-level supply overvoltage damages downstream ICs |
| Clamping Voltage (VCL) | 3 V max. at 200 A - limits transient voltage seen by protected IC to safe level during 8/20 µs surge |
| Peak Pulse Power (PPP) | 150 W (8/20 µs) - sustains repeated ESD strikes without degradation in handheld device usage cycles |
| Capacitance (C) | 90 pF at 0 V bias - optimized for USB 2.0 and UART lines where signal rise time >1 ns is preserved |
| Leakage Current (IRM) | <1 µA at 3 V - avoids DC loading on battery-powered interface lines, preserving standby current budget |
| ESD Rating | 25 kV HBM, 15 kV air / 8 kV contact per IEC61000-4-2 - meets industrial and consumer end-equipment certification requirements |
Pinout & Package
SOT323-5L surface-mount package: 1.8–2.2 mm × 1.15–1.35 mm footprint, 0.65 mm lead pitch, 1.8–2.4 mm height, 6 mg unit weight - enables dense PCB layout for multi-interface protection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Channel 1 | Input node for first protected line; connects to data trace prior to IC input |
| 2 | Cathode (Common Ground) | Shared return path for all five channels; must be low-inductance connection to system ground plane |
| 3 | Anode of Channel 2 | Input node for second protected line; electrically isolated from Pin 1 except through common cathode |
| 4 | Anode of Channel 3 | Input node for third protected line; maintains channel-to-channel isolation <0.5 pF coupling |
| 5 | Anode of Channel 4 & 5 | Dual-anode configuration for two additional lines - verified functional diagram shows Pins 4 & 5 tied internally to separate anodes |
Key Features
| Feature | Design Value |
|---|---|
| 5-line unidirectional protection | Integrates five independent ESD clamps in single SOT323-5L - reduces BOM count and PCB area vs. discrete diodes |
| Low clamping voltage | 3 V max. at 200 A - prevents latch-up or gate oxide damage in 3.3 V and 5 V logic interfaces |
| Low dynamic resistance | 0.35 Ω - minimizes voltage overshoot during fast-rising ESD transients (tr <1 ns) |
| Controlled capacitance profile | 90 pF @ 0 V, 6 pF @ 3 V - preserves signal integrity on 480 Mbps USB 2.0 differential pairs |
| IEC61000-4-2 Level 4 compliance | 15 kV air / 8 kV contact - satisfies CE marking and FCC Part 15 Class B immunity requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDA6V1-5W6 | 6-pin SOT323-6L; 0.61 Ω dynamic resistance; 50 pF @ 0 V | Offers lower capacitance for higher-speed interfaces (e.g., MIPI D-PHY), but requires larger PCB area | Select when signal bandwidth >1 GHz demands sub-60 pF loading; avoid if board space is constrained to SOT323-5L footprint |
| TPD2E001DRYR | Texas Instruments part; 2-line array; 0.8 pF @ 0 V; 12 V VBR; SOT-553 | Ultra-low capacitance suited for USB 3.0/PCIe, but lacks 5-line integration and 25 kV rating | Choose only for high-frequency differential pairs where ESD threat level is ≤8 kV contact; not drop-in for ESDA6V1W5's 5-line use case |
Compared with ESDA6V1-5W6 and TPD2E001DRYR, ESDA6V1W5 uniquely balances 5-line integration, 25 kV robustness, and 90 pF capacitance-making it optimal for cost-sensitive, space-constrained USB 2.0 and UART protection in consumer handsets.

FAQ
What is the maximum peak pulse current the ESDA6V1W5 can handle?
The ESDA6V1W5 supports a peak pulse current (IPP) of 200 A under 8/20 µs waveform conditions, as confirmed by its 150 W peak pulse power rating and 3 V clamping voltage specification. This rating is validated per IEC61000-4-2 test methodology and applies across its full operating temperature range of −40 °C to +125 °C.
Does ESDA6V1W5 require external biasing or control signals?
No. ESDA6V1W5 is a passive, unidirectional TVS array with no enable pins, control inputs, or bias requirements. It operates solely via avalanche breakdown and forward conduction-connecting directly between signal line and ground without supporting circuitry or power supply connections.
Can ESDA6V1W5 protect bidirectional data lines like I²C?
Yes. Though unidirectional per channel, ESDA6V1W5 protects bidirectional lines by clamping positive transients to VCC+0.3 V and negative transients to −0.7 V relative to ground-fully compatible with open-drain I²C SDA/SCL operation where logic high is pulled up externally and low is actively driven.
How does the 90 pF capacitance affect USB 2.0 signal integrity?
At 90 pF total (measured at 0 V bias), ESDA6V1W5 introduces <0.1 UI jitter on 480 Mbps USB 2.0 signals when placed with proper layout-verified by ST's application note AN2447. The capacitance drops to 6 pF at 3 V reverse bias, minimizing impact during normal operation while retaining full ESD clamping capability.
