Product details
Overview
ESDA14V2SC6Y from STMicroelectronics is an automotive-grade quad unidirectional Transil™ TVS diode array for ESD and EOS transient voltage suppression on data and signal lines. It features 14.2 V minimum breakdown voltage, 400 W peak pulse power (8/20 µs), 14 A peak pulse current, ±30 kV ESD immunity per ISO 10605, and AEC-Q101 qualification-designed for protecting CAN, LIN, and sensor interface lines in vehicle infotainment and body control modules.
For engineers reviewing the ESDA14V2SC6Y datasheet, ESDA14V2SC6Y pinout, ESDA14V2SC6Y application, or ESDA14V2SC6Y equivalent, key selection criteria include clamping voltage at rated IPP, line capacitance (100 pF typ.), junction temperature range (–40 °C to +150 °C), and SOT23-6L package compatibility with high-density automotive PCB layouts.
Technical Context
The ESDA14V2SC6Y integrates four independent unidirectional TVS elements in a single monolithic silicon chip, each clamping positive transients just above VCC and negative transients to ~0.7 V below ground. Its architecture enables simultaneous protection of four bidirectional signal paths without internal coupling.
It meets stringent automotive transient immunity standards: ISO 7637-2 Pulse 1 (–100 V), Pulse 2a (+50 V), Pulse 3a (–150 V), and Pulse 3b (+100 V), with clamping voltage ≤12 V at 14 A (8/20 µs) and leakage current <5 µA at 14.2 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 14.2 V min / 15.8 V max - defines minimum trigger threshold for transient clamping |
| Clamping Voltage VCL | 12 V max at 14 A (8/20 µs) - ensures protected ICs see safe voltage during surge events |
| Peak Pulse Power | 400 W (8/20 µs) - sustains high-energy transients common in 12 V automotive systems |
| Line Capacitance CLINE | 100 pF typ. - low enough to avoid signal integrity degradation on 1–5 Mbps CAN/LIN buses |
| ESD Withstand Level | ±30 kV contact & air discharge (ISO 10605, 150/330 pF) - exceeds automotive ESD test requirements |
| Junction Temp Range | –40 °C to +150 °C - supports operation under hood and near engine control units |
| AEC-Q101 Qualified | Yes - validated for automotive reliability including HTOL, TC, and ESD stress testing |
Pinout & Package
ESDA14V2SC6Y is housed in a lead-free, RoHS-compliant SOT23-6L package (3.05 × 1.75 × 1.30 mm), optimized for automated placement and reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode 1 | Input terminal for first unidirectional TVS path (cathode tied internally to VCC) |
| 2 | Cathode 1 | Clamp output node for Channel 1 - connects to protected signal line |
| 3 | Anode 2 | Input terminal for second unidirectional TVS path |
| 4 | Cathode 2 | Clamp output node for Channel 2 |
| 5 | Anode 3 | Input terminal for third unidirectional TVS path |
| 6 | Cathode 3 | Clamp output node for Channel 3 - pin 6 is not used for Channel 4; fourth channel shares cathode with pin 2 or uses dedicated layout per Figure 1 in datasheet |
Key Features
| Feature | Design Value |
|---|---|
| Quad unidirectional protection | Four independent TVS elements enable discrete-level surge suppression on four signal lines without shared clamping nodes |
| Low clamping voltage | VCL ≤12 V at 14 A ensures downstream logic ICs (e.g., CAN transceivers) remain within absolute maximum ratings |
| Automotive-grade reliability | AEC-Q101 qualification confirms suitability for safety-critical vehicle subsystems with zero infant mortality |
| Low line capacitance | 100 pF typical minimizes signal rise-time distortion on high-speed serial links up to 5 Mbps |
| Thermal robustness | Rated for continuous operation up to +150 °C junction temperature - compatible with under-hood thermal environments |
Applications
| Infotainment Data Lines | CAN Bus Interface |
|---|---|
Use Scenario: Protecting USB, HDMI, or LVDS interfaces in head units and display modules against ESD during service or user interaction. IC Role / Device Role: Unidirectional TVS array clamping transients between signal line and local VCC/GND rails. Use Value: Prevents latch-up or permanent damage to high-speed SerDes ICs while maintaining <100 pF loading for signal integrity. | Use Scenario: Shielding CAN_H/CAN_L differential pairs in body control modules from load dump and inductive switching noise. IC Role / Device Role: Four-channel TVS providing independent clamping for both lines plus auxiliary signals (e.g., wake-up line). Use Value: Meets ISO 7637-2 Pulse 1/2a/3a/3b immunity requirements without adding external bias networks. |
| LIN Network Nodes | Sensor Signal Conditioning |
Use Scenario: Securing LIN slave nodes (e.g., door lock actuators, mirror controls) against ESD during assembly and field operation. IC Role / Device Role: Single-device protection for LIN bus line and associated diagnostic or power-enable pins. Use Value: Enables compact 6-pin footprint for full 3-line protection (bus + two control lines), reducing BOM count vs. discrete diodes. | Use Scenario: Safeguarding analog outputs of pressure, temperature, or position sensors connected to MCU ADC inputs. IC Role / Device Role: Low-leakage (<5 µA) TVS array preventing overvoltage-induced offset drift or input stage damage. Use Value: Maintains measurement accuracy by limiting clamping voltage to ≤12 V while supporting –40 °C to +150 °C ambient operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDA14V2SC5Y | Same electrical specs but SOT23-5L package (5-pin, no dedicated GND pin); lower thermal dissipation margin | Used where board space is tighter and only three signal lines require protection | Select when footprint area is constrained and fourth channel is unused; verify thermal derating for sustained surges |
| TPD4E05U06DBVR | Lower VBR (5.5 V), higher CLINE (12 pF), same SOT23-6L - designed for 3.3 V logic, not 12 V automotive | Targeted at consumer USB/USB-C ports, not ISO 7637-2 compliant systems | Only suitable for non-automotive, low-voltage data lines; lacks AEC-Q101 and pulse 1/3a rating |
Compared with ESDA14V2SC6Y, ESDA14V2SC5Y offers identical protection performance in a smaller footprint but reduced thermal margin, while TPD4E05U06DBVR provides lower-capacitance protection for 3.3 V systems but fails automotive surge compliance and high-temperature operation.

FAQ
What is the maximum clamping voltage of ESDA14V2SC6Y at 14 A?
The maximum clamping voltage is 12 V under an 8/20 µs waveform at 14 A peak pulse current, as specified in Table 3 of the official ST datasheet (DocID028400 Rev 1). This value ensures protected components remain within safe operating limits during ESD and load-dump events.
Does ESDA14V2SC6Y support bidirectional signal lines like CAN_H/CAN_L?
No - ESDA14V2SC6Y contains four unidirectional TVS elements. For bidirectional protection on differential lines, two devices are typically used: one for CAN_H-to-VCC/GND and another for CAN_L-to-VCC/GND, or a dedicated bidirectional array such as ESDALYV5-1U2.
Is the SOT23-6L package compatible with standard reflow profiles?
Yes - ST specifies a JEDEC-compliant reflow profile with peak temperature ≤260 °C for 10 seconds (Table 2), and recommends halide-free, "no-clean" solder paste with fine particles (20–45 µm). The device is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1.
How does ESDA14V2SC6Y differ from ESDA6V1SC6Y in system-level protection?
ESDA14V2SC6Y has higher VBR (14.2 V vs. 6.1 V) and is intended for 12 V automotive supply domains, whereas ESDA6V1SC6Y targets 3.3–5 V logic interfaces. Using ESDA6V1SC6Y on a 12 V line would cause premature conduction and potential thermal failure due to excessive leakage at normal operating voltage.
