Product details
Overview
ESDA6V1-5SC6 from STMicroelectronics is a 5-channel unidirectional Transil™ ESD protection array in SOT23-6L (SC-59) package, designed for I/O line protection on high-density PCBs. It delivers 6.1 V min. breakdown voltage, <1 µA leakage at 5 V, 30 A peak pulse current (8/20 µs), and clamps to ≤12 V at 15 A - deployed in cellular phone handsets, USB interfaces, and set-top box HDMI ports.
For engineers reviewing the ESDA6V1-5SC6 datasheet, ESDA6V1-5SC6 pinout, ESDA6V1-5SC6 application, or ESDA6V1-5SC6 equivalent, key selection criteria include clamping voltage under IEC61000-4-2 level 4 (±15 kV air / ±8 kV contact), 50 pF capacitance at 0 V bias, and compatibility with 2.5 µs transient waveforms in high-speed data lines.
Technical Context
The device integrates five independent unidirectional TVS diodes in a single monolithic silicon chip, each featuring avalanche-triggered clamping with dynamic resistance of 590 mΩ. Its architecture supports simultaneous multi-line ESD suppression without cross-talk, maintaining signal integrity up to 100 MHz due to low 50 pF capacitance per channel.
It complies with IEC61000-4-2 level 4 (15 kV air / 8 kV contact), MIL-STD-883C method 3015-7 Class 3 HBM (>4 kV), and operates across –40°C to +125°C ambient. The αT temperature coefficient (1.25 × 10⁻⁴ /°C) ensures predictable VBR drift over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 6.1 V min. - guarantees reliable turn-on before damage to downstream 5 V logic or USB PHY circuits |
| Clamping Voltage (VCL) | ≤12 V at 15 A (2.5 µs pulse) - limits stress on protected ICs during ESD events |
| Leakage Current (IRM) | <1 µA at 5 V - avoids signal distortion or power drain in battery-powered handhelds |
| Capacitance (C) | 50 pF at 0 V - enables use on USB 2.0 (480 Mbps) and HDMI DDC lines without bandwidth degradation |
| Peak Pulse Power (PPP) | 100 W (8/20 µs) - sustains repeated ESD strikes per IEC61000-4-2 without parametric shift |
| Operating Temp Range | –40°C to +125°C - supports automotive infotainment and industrial edge node deployments |

| 150°C junction temperature rating | Enables placement near heat-generating SoCs or PMICs without derating |
| IEC61000-4-2 level 4 certified | Validated for 15 kV air / 8 kV contact discharge - meets CE/UL requirements out-of-box |
Applications
| USB 2.0 Interface Protection | HDMI DDC/CEC Line Protection |
|---|---|
Use Scenario: Protecting D+/D– lines of embedded USB host controllers in portable medical devices. IC Role / Device Role / Timing Role: Unidirectional clamping diode array placed within 5 mm of connector, shunting ESD transients to GND before reaching PHY.

IC Role / Device Role / Timing Role: Low-capacitance TVS array mounted directly at HDMI receptacle, suppressing contact discharge on hot-plug insertion. Use Value: Maintains DDC communication integrity (<100 ns response) while limiting VCL to <12 V at 15 A surge. |
| Cellular Handset Keypad/Touch Panel | Industrial RS-485 Node Protection |
Use Scenario: Guarding capacitive touch controller I/Os and mechanical keypad scan lines in GSM/LTE handsets. IC Role / Device Role / Timing Role: Five-channel array assigned to five independent sensor inputs, each with dedicated anode-to-GND path. Use Value: Enables compact layout under display bezel; <1 µA leakage preserves battery life over 3-year shelf life. | Use Scenario: Safeguarding RS-485 transceiver A/B lines and enable/control pins in factory automation gateways. IC Role / Device Role / Timing Role: Dual-channel configuration (I/O1/I/O2 + GND) for differential pair, remaining three channels for control signals. Use Value: Withstands 30 A surges per IEC61000-4-5 (surge immunity), preventing bus lockup during motor drive switching noise. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | Lower capacitance (12 pF), but only 2 channels; 6.8 V VBR; 12 V VCL @ 1 A | Optimized for high-speed USB 3.0/PCIe; insufficient channel count for 5-line systems | Select when protecting two ultra-high-speed lines where capacitance is critical and channel count is ≤2 |
| SP1006-04UTG | 4-channel unidirectional array; 5.5 V VBR; 15 V VCL @ 12 A; 100 pF/channel | Higher capacitance limits use to <10 Mbps interfaces; lacks fifth channel | Choose for cost-sensitive 4-line applications where 100 pF is acceptable (e.g., legacy RS-232) |
Compared with TPD2E001DRYR and SP1006-04UTG, ESDA6V1-5SC6 uniquely balances 5-channel integration, 50 pF capacitance, and IEC61000-4-2 level 4 compliance - making it optimal for space-constrained, multi-interface consumer electronics requiring full-system ESD coverage.

FAQ
What is the maximum allowable trace length between ESDA6V1-5SC6 and the protected connector?
Trace length must be ≤5 mm from device pad to connector pin to minimize inductance-induced voltage overshoot during 15 kV ESD events. Longer traces increase VCL beyond 12 V, risking damage to downstream ICs. Layout best practice requires direct routing with no vias or stubs between I/O pins and protected lines.
Does ESDA6V1-5SC6 support bidirectional signal lines like RS-485?
No - ESDA6V1-5SC6 is strictly unidirectional (anode-to-GND configuration). For bidirectional differential lines such as RS-485 A/B, a dual-channel bidirectional array like ESDALC6V1-1M2 is required. Using this part on bidirectional lines would block negative signal excursions.
Can ESDA6V1-5SC6 replace discrete 0402 TVS diodes in existing designs?
Yes - its SOT23-6L footprint replaces five 0402 discrete diodes plus one 0402 GND capacitor, reducing component count by 80% and eliminating assembly misalignment risk. Footprint conversion requires updating land patterns to match 0.95 mm pitch and 1.75 mm width per JEDEC MO-178.
Is lead-free reflow compatible with the ESDA6V1-5SC6 package?
Yes - the device is qualified for lead-free reflow per JEDEC J-STD-020 Rev E, with peak temperature tolerance up to 260°C for 10 seconds at 5 mm from case body. Thermal profile must maintain ramp rate ≤3°C/s and avoid exceeding 150°C junction temperature during preheat.
