Product details
Overview
ESDA14V2SC5Y from STMicroelectronics is an automotive-grade quad unidirectional Transil™ TVS diode array designed for ESD and EOS transient overvoltage protection on data and transmission lines. It features a 14.2 V minimum breakdown voltage, 400 W peak pulse power (8/20 µs), 12 V clamping voltage at 14 A, ±30 kV ESD immunity per ISO 10605, and AEC-Q101 qualification - deployed in infotainment serial buses and CAN-FD signal paths.
For engineers reviewing the ESDA14V2SC5Y datasheet, ESDA14V2SC5Y pinout, ESDA14V2SC5Y application, or ESDA14V2SC5Y equivalent, key selection criteria include unidirectional clamping behavior, SOT23-5L footprint compatibility, ISO 7637-2 Pulse 1/2a/3a surge response, junction temperature range (–40 °C to +150 °C), and line capacitance (100 pF typical) for high-speed signal integrity.
Technical Context
The ESDA14V2SC5Y 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 signal lines without cross-coupling.
It meets automotive transient immunity requirements per ISO 7637-2: Pulse 1 (–100 V), Pulse 2a (+50 V), Pulse 3a (–150 V), and Pulse 3b (+100 V), with specified clamping performance up to 14 A peak pulse current under 8/20 µs waveform conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 14.2 V min / 15.8 V max at 1 mA - defines minimum overvoltage threshold before conduction begins |
| Clamping Voltage (VCL) | 12 V max at 14 A (8/20 µs) - limits downstream IC stress during surge events |
| Peak Pulse Power | 400 W (8/20 µs) - supports robust handling of automotive load dump and inductive switching surges |
| ESD Withstand Level | ±30 kV contact & air discharge (ISO 10605, C = 150/330 pF) - exceeds IEC 61000-4-2 Level 4 |
| Line Capacitance (CLINE) | 100 pF typ at 0 V - preserves signal integrity on ≤10 Mbps CAN or LIN bus interfaces |
| Junction Temperature Range | –40 °C to +150 °C - enables placement near powertrain or engine-control electronics |
Pinout & Package
SOT23-5L package: 5-pin surface-mount plastic package with gull-wing leads, UL94 V0 rated epoxy, lead-free, ECOPACK® compliant. Dimensions: 2.80–3.05 mm × 1.50–1.75 mm × 1.30 mm max height.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode 1 | Input terminal for first protected signal line; connects to trace requiring ESD clamping |
| 2 | Cathode Common | Shared cathode node tied to system ground or local reference plane |
| 3 | Anode 2 | Input terminal for second protected signal line |
| 4 | Anode 3 | Input terminal for third protected signal line |
| 5 | Anode 4 | Input terminal for fourth protected signal line |
Key Features
| Feature | Design Value |
|---|---|
| Quad unidirectional protection | Four independent TVS paths in one SOT23-5L footprint - reduces board area vs. discrete diodes |
| AEC-Q101 qualification | Validated for automotive under-hood and cabin environments - supports PPAP and functional safety readiness |
| Low leakage current | <5 µA at 14.2 V - avoids signal distortion or bias shift on high-impedance sensor inputs |
| Thermal stability | αT = 10 × 10−4/°C - predictable VBR drift across full operating temperature range |
Applications
| Automotive Infotainment | CAN FD Data Bus |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDA14V2SC6Y | Same electrical specs but SOT23-6L package with dedicated cathode pin (Pin 6) | Requires PCB redesign due to extra pin and different footprint; allows separate cathode routing | Select when individual cathode control or thermal separation from shared ground is required |
| TPD4E05U06DQAR | Lower VBR (5.5 V), lower clamping (8.5 V @ 4 A), 12 pF CLINE, same SOT23-5L | Better suited for 3.3 V logic interfaces; insufficient for 12 V automotive bus clamping | Choose only for low-voltage digital I/O protection - not a drop-in replacement for 14.2 V systems |
Compared with ESDA14V2SC6Y, the SOT23-5L variant saves board space and simplifies layout; versus TPD4E05U06DQAR, it delivers higher voltage tolerance and automotive surge compliance at the cost of higher line capacitance.

FAQ
What is the maximum clamping voltage of ESDA14V2SC5Y under ISO 7637-2 Pulse 1?
The ESDA14V2SC5Y clamps to ≤12 V at 14 A peak pulse current (8/20 µs), which corresponds to the worst-case ISO 7637-2 Pulse 1 condition (–100 V). Measured waveforms in Figure 7 confirm sub-12 V clamping across –100 V to –150 V input transients, ensuring downstream CAN transceivers remain within safe operating voltage limits.
Can ESDA14V2SC5Y be used on bidirectional data lines like RS-485?
No - ESDA14V2SC5Y is unidirectional only, with cathode common to all four anodes. For bidirectional lines such as RS-485, a symmetric TVS array like ESDALC6V1-1U2 is required. Using this part on bidirectional signals would forward-bias during negative half-cycles, causing excessive leakage or failure.
Is the SOT23-5L package compatible with standard reflow profiles for lead-free assembly?
Yes - ST specifies a standard lead-free reflow profile with peak temperature of 260 °C for 10 seconds (Table 2), matching IPC-J-STD-020 requirements. The device's ECOPACK® construction and thermal mass allow reliable solder joint formation using conventional convection reflow ovens without special ramp rates or nitrogen atmosphere.
How does ESDA14V2SC5Y differ from generic 14 V Zener-based TVS arrays?
Unlike discrete Zener solutions, ESDA14V2SC5Y uses monolithic Transil™ silicon technology with tightly controlled VBR tolerance (14.2–15.8 V), lower dynamic impedance, and guaranteed AEC-Q101 qualification. Its integrated quad structure eliminates inter-device parameter mismatch and ensures consistent clamping across all four channels under simultaneous surge events.
