Product details
Overview
ESDALC6V1P5 from STMicroelectronics is a low-capacitance, 4-channel unidirectional ESD protection diode array in SOT-665 package, designed to clamp transient overvoltages on high-speed data lines. It features 6.1 V minimum breakdown voltage, 7.5 pF capacitance at 3 V, <100 nA leakage, and meets IEC 61000-4-2 Level 4 (20 kV air / 8 kV contact discharge) for robust ESD immunity in USB, HDMI, and Ethernet interfaces.
For engineers reviewing the ESDALC6V1P5 datasheet, ESDALC6V1P5 pinout, ESDALC6V1P5 application, or ESDALC6V1P5 equivalent, key selection criteria include channel count, clamping voltage under 8 A IPP, dynamic impedance ≤4.5 Ω, junction temperature range (–40 °C to +150 °C), and RoHS-compliant SOT-665 footprint compatibility with high-density PCB layouts.
Technical Context
This monolithic Transil array uses silicon avalanche diode structures optimized for fast response (<1 ns) to ESD transients while maintaining low signal distortion. Each of its four unidirectional channels operates independently with symmetrical clamping: positive transients clamp just above VCC (e.g., ~9.5 V at 8 A), negative transients clamp to ~–1.5 V (diode drop below ground).
The device achieves 7.5 pF capacitance at 3 V reverse bias-critical for preserving signal integrity in >100 Mbps digital interfaces-and sustains 30 W peak pulse power (8/20 µs waveform) without degradation across –40 °C to +150 °C operating temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 6.1 V min - ensures reliable triggering above 3.3 V/5 V logic rails without false triggering |
| Clamping Voltage (VCL) | ≤12 V at 8 A IPP - limits downstream IC stress during IEC 61000-4-2 contact discharge events |
| Junction Capacitance | 7.5 pF at 3 V - enables use in USB 2.0, HDMI, and LVDS without signal rise-time degradation |
| Leakage Current (IR) | <100 nA at 3 V - prevents DC loading on sensitive analog or reference inputs |
| Dynamic Impedance (Rd) | 4.5 Ω typ - determines voltage overshoot during fast ESD current injection |
| ESD Withstand (IEC 61000-4-2) | 20 kV air / 8 kV contact - exceeds Level 4 industrial requirement for end-equipment certification |
| Operating Temperature | –40 °C to +150 °C - supports automotive infotainment and industrial control environments |
Pinout & Package
SOT-665 is a 5-pin, ultra-small surface-mount package (1.7 × 1.3 × 0.62 mm) with exposed pad for thermal enhancement and mechanical stability. Pin 1 is marked with dot; pins are arranged in single-row configuration with 0.5 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode 1 | Input terminal for first unidirectional ESD path - connects to protected data line (e.g., USB D+) |
| 2 | Cathode 1 | Return path to VCC - clamps positive transients to supply rail |
| 3 | Common Cathode | Shared cathode node for all four channels - ties to local VCC plane for low-inductance clamping |
| 4 | Anode 2 | Input terminal for second unidirectional ESD path - e.g., USB D– |
| 5 | Anode 3 | Input terminal for third unidirectional ESD path - e.g., ID or auxiliary signal line |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDALC6V1P6 | SOT-666IP package (1.7 × 1.7 × 0.6 mm); identical electrical specs but different pinout and footprint | Requires PCB redesign due to 5-pin vs. 6-pin layout and shifted anode/cathode mapping | Select when SOT-666IP tape-and-reel logistics or thermal mass requirements outweigh footprint compatibility needs |
| TPD2E001DRYR | Texas Instruments part: 2-channel, 12 pF capacitance, 15 kV IEC 61000-4-2, SOT-553 package | Limited to dual-line protection; higher capacitance reduces usable bandwidth to ~250 MHz | Choose only for cost-sensitive, lower-speed applications where 4-channel density is not required |
Compared with ESDALC6V1P6 and TPD2E001DRYR, the ESDALC6V1P5 uniquely delivers 4-channel protection in the smallest industry-standard footprint (SOT-665), lowest capacitance (7.5 pF), and highest IEC 61000-4-2 rating (20 kV air), making it optimal for space-constrained, high-speed interface designs requiring full differential pair coverage.

FAQ
What is the maximum peak pulse current (IPP) this device can handle?
The ESDALC6V1P5 sustains 8 A peak pulse current (8/20 µs waveform) at 25 °C ambient, delivering ≤12 V clamping voltage. At elevated junction temperatures (up to +150 °C), derating applies per Figure 4 in DS4887 Rev 10, reducing usable IPP to ~5.5 A while maintaining VCL <13.5 V.
Does this part support bidirectional ESD protection?
No. The ESDALC6V1P5 is strictly unidirectional: each channel clamps positive transients to VCC and negative transients to ground. For bidirectional protection (e.g., AC-coupled lines), ST recommends ESDALC6V1-1U2 or ESDALC12-2M5, which use symmetrical avalanche structures.
Can this device be used on 1.8 V logic interfaces?
Yes. Its 6.1 V minimum breakdown voltage provides sufficient margin above 1.8 V rails, and leakage remains <100 nA at 1.8 V reverse bias. However, clamping action begins near 7.5 V, so system-level overvoltage tolerance must accommodate that threshold.
Is the SOT-665 package compatible with standard reflow profiles?
Yes. The SOT-665 package supports JEDEC J-STD-020-compliant lead-free reflow, with peak temperature up to 245 °C (240–245 °C range), ramp rates ≤3 °C/s, and 60-second dwell within specification-verified in Figure 27 of DS4887 Rev 10.
