Product details
Overview
ESDALC6V1W5 from STMicroelectronics is a quad unidirectional Transil™ ESD protection array in SOT323-5L package, designed for high-speed data line protection with 6.1 V minimum breakdown voltage, 7.5 pF capacitance at 3 V, and 25 kV HBM ESD immunity. It clamps positive transients above logic supply and negative transients to ~0.7 V below ground, deployed in USB, HDMI, and cellular phone I/O interfaces.
For engineers reviewing the ESDALC6V1W5 datasheet, ESDALC6V1W5 pinout, ESDALC6V1W5 application, or ESDALC6V1W5 equivalent, key selection criteria include low-capacitance signal integrity preservation, precise 6.1 V standoff compliance for 3.3 V/5 V systems, IEC61000-4-2 Level 4 (15 kV air / 8 kV contact) certification, and SOT323-5L footprint compatibility with space-constrained portable designs.
Technical Context
This device integrates four independent unidirectional TVS diodes in a single monolithic silicon chip, each configured as a low-leakage (≤1 µA), low-capacitance (7.5 pF @ 3 V) clamp with dynamic resistance of 1.1 Ω. Its clamping voltage is 12 V at 15 A (2.5 µs pulse), enabling robust transient suppression without signal distortion on high-frequency lines.
The ESDALC6V1W5 operates across –40°C to +150°C, with voltage temperature coefficient αT = 6 × 10–4/°C and peak pulse power rating of 25 W (8/20 µs). It complies fully with IEC61000-4-2 and MIL-STD-883E Method 3015-7 Class 3, supporting fail-safe protection in hot-plug and electrostatic-prone environments.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z6.0T1G (ON Semi) | Single-channel, 6.0 V VBR, 12 pF @ 3 V, SOD-523 | Requires four discrete units; higher total capacitance degrades >200 MHz signals | Choose only when board layout allows separate placement and cost-per-channel is prioritized over density |
| TPD2E001DRYR (TI) | Quad, 5.5 V VBR, 10 pF @ 3 V, X2SON-6 | Lower clamping (9.5 V @ 1 A) but higher capacitance - less suitable for USB 2.0 | Select if tighter 5.5 V standoff is required for 2.5 V I/O domains, accepting reduced HF margin |
Compared with ESD5Z6.0T1G and TPD2E001DRYR, the ESDALC6V1W5 delivers superior high-frequency performance (7.5 pF) and integrated quad layout in minimal area, making it optimal for space- and bandwidth-critical mobile interfaces where single-part reliability outweighs per-channel cost trade-offs.

FAQ
What is the maximum peak pulse current the ESDALC6V1W5 can handle?
The ESDALC6V1W5 is rated for 15 A peak pulse current (2.5 µs rectangular waveform) with a clamping voltage of 12 V. Its 25 W peak pulse power rating (8/20 µs) supports repetitive surge events typical in IEC61000-4-2 testing, provided PCB thermal relief and ground plane design meet ST's recommended layout guidelines.
Does the ESDALC6V1W5 support bidirectional signal lines like USB D+ and D−?
No - the ESDALC6V1W5 contains four unidirectional diodes, each with anode tied to I/O pins and cathodes common to GND. For true bidirectional protection (e.g., USB full-duplex), external series resistors or complementary dual-diode configurations are required; this device is intended for unidirectional or DC-biased differential lines.
How does the 7.5 pF capacitance impact 480 Mbps USB 2.0 signal integrity?
At 7.5 pF, the ESDALC6V1W5 introduces <0.5 dB insertion loss and <1° phase shift at 240 MHz (Nyquist frequency of USB 2.0), well within USB-IF eye diagram mask tolerances. Measured eye diagrams show no measurable jitter increase or rise-time degradation when placed within 5 mm of the connector per ST application note AN2827.
Is the SOT323-5L package compatible with standard reflow profiles?
Yes - the SOT323-5L package is qualified for lead-free reflow per JEDEC J-STD-020 Rev E, with maximum lead temperature of 260°C for 10 seconds. ST specifies ramp rates ≤3°C/s, peak temperature 245±5°C, and time above 220°C of 40–80 s; compatibility is confirmed in ST's package mechanical data sheet (Doc ID 13377).
