Product details
Overview
ESDA6V1-5SC6Y from STMicroelectronics is a monolithic 5-line unidirectional TVS array in SOT23-6L package, designed to protect data and transmission lines against ESD transients. It features 6.1 V breakdown voltage (min), 5.2 V clamping voltage at 7 A, ±30 kV air/±18 kV contact ESD immunity per IEC 61000-4-2, and operates from −40 °C to +150 °C - deployed in automotive infotainment interfaces and CAN/LIN bus signal lines.
For engineers reviewing the ESDA6V1-5SC6Y datasheet, ESDA6V1-5SC6Y pinout, ESDA6V1-5SC6Y application, or ESDA6V1-5SC6Y equivalent, key selection criteria include unidirectional clamping behavior, 7 A peak pulse current capability, ISO 7637-3 Pulse 3a/3b compliance, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device integrates five independent unidirectional TVS diodes in a single SOT23-6L package, each configured with anode-to-ground topology for positive transient clamping above VCC and cathode-to-ground for negative transient suppression down to ~−0.7 V. Its layout supports high-density routing on compact PCBs without requiring external biasing or control signals.
It meets stringent automotive transient standards: ISO 10605 (150 pF/330 Ω and 330 pF/330 Ω), ISO 7637-3 Pulse 3a (−150 V) and Pulse 3b (+100 V), and complies with UL 94 V0 flammability rating. The junction temperature range (−40 °C to +150 °C) enables use in under-hood and cabin modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 6.1–7.2 V min–max at 1 mA; ensures reliable turn-on before logic-level damage occurs on 5 V systems. |
| Clamping Voltage (VCL) | 5.2 V max at 7 A (8/20 µs); limits downstream IC stress to safe levels during ESD events. |
| Peak Pulse Current (IPP) | 7 A (8/20 µs); sustains high-energy transients without thermal runaway or parametric shift. |
| ESD Rating (IEC 61000-4-2) | ±30 kV air / ±18 kV contact; exceeds Level 4 requirements for robust human-body-model protection. |
| Operating Temperature | −40 °C to +150 °C; supports placement in engine control units, body controllers, and ADAS sensor interfaces. |
| Package | SOT23-6L; 6-pin surface-mount footprint with 0.95 mm pitch, optimized for automated assembly and space-constrained layouts. |
Pinout & Package
SOT23-6L is a 6-pin, lead-free, UL 94 V0-compliant plastic package with exposed pad not present; dimensions conform to JEDEC MO-178, with 2.8–3.05 mm length, 1.5–1.75 mm width, and 0.9–1.45 mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| I/O1 | Anode of Channel 1 | Input line protected by unidirectional TVS; clamps positive transients to ~6.1 V, negative to ~−0.7 V. |
| I/O2 | Anode of Channel 2 | Independent ESD path for second signal line; shares common cathode (GND) but no inter-channel coupling. |
| GND | Common Cathode Terminal | Reference node for all five TVS channels; must be low-inductance connection to system ground plane. |
| I/O5 | Anode of Channel 5 | Fifth protected line; identical electrical behavior to I/O1–I/O4; supports full 5-line differential or single-ended interface. |
| I/O3 | Anode of Channel 3 | Third dedicated ESD clamp; enables protection of LIN bus, UART, or I²C SDA/SCL without shared impedance. |
| I/O4 | Anode of Channel 4 | Fourth isolated protection node; maintains channel independence up to 100 MHz signal integrity. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including powertrain, chassis, and infotainment systems per stress test requirements. |
| 5 unidirectional TVS functions | Enables discrete-level protection of five separate signal lines in one footprint-reducing BOM count and board area by >70% vs. discrete diodes. |
| ISO 7637-3 Pulse 3a/3b compliant | Withstands −150 V (Pulse 3a) and +100 V (Pulse 3b) load-dump-like transients typical in 12 V vehicle networks. |
| Low leakage current | ≤1 µA at 5.2 V (VRM); avoids signal distortion or DC loading on high-impedance analog or digital inputs. |
| MSL Level 1 | Unlimited floor life at ≤30 °C/60% RH; eliminates bake-out requirement prior to reflow soldering. |
Applications
| Infotainment Interface Protection | Body Control Module Signal Lines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDALC6V1-5SC6 | Same SOT23-6L footprint; lower VBR (5.25–6.15 V), higher Cline (100 pF typ.), non-AEC-Q101 rated. | Targeted at consumer-grade USB/UART protection; lacks ISO 7637-3 validation. | Select only for cost-sensitive non-automotive designs where ESD-only protection suffices. |
| TPD2E001DRYR | 2-channel unidirectional TVS in SOT-5X3; VBR = 5.5 V, Cline = 12 pF, IPP = 4 A, AEC-Q101 qualified. | Limited to dual-line protection; requires two devices for 5-line coverage, increasing layout area and BOM complexity. | Prefer when ultra-low capacitance (<15 pF) is mandatory for >100 MHz serial links, despite channel count limitation. |
Compared with ESDALC6V1-5SC6 and TPD2E001DRYR, the ESDA6V1-5SC6Y uniquely delivers 5-channel AEC-Q101 protection with balanced clamping (5.2 V), high surge robustness (7 A), and automotive transient compliance - making it optimal for integrated signal protection in space-constrained automotive ECUs.

FAQ
What is the maximum clamping voltage under 7 A IPP conditions?
The ESDA6V1-5SC6Y specifies a maximum clamping voltage of 5.2 V at 7 A (8/20 µs waveform), measured at Tamb = 25 °C. This value remains ≤5.8 V across its full operating temperature range (−40 °C to +150 °C), ensuring consistent overvoltage limiting for downstream 5 V logic.
Does this device support bidirectional ESD protection?
No - the ESDA6V1-5SC6Y is strictly unidirectional. Each channel connects anode to I/O and cathode to GND, enabling clamping of positive transients above VCC and negative transients to ~−0.7 V. For bidirectional protection, ST recommends the ESDALC12-2M5 or similar symmetric arrays.
Can it be used on 3.3 V logic interfaces?
Yes, but with design caution: its 6.1 V minimum breakdown voltage provides adequate margin above 3.3 V rails, and clamping at 5.2 V prevents damage. However, ensure system-level testing confirms no false triggering during 3.3 V supply ripple or overshoot, especially in hot-plug scenarios.
Is the SOT23-6L package compatible with standard reflow profiles?
Yes - the device is rated MSL Level 1 and qualified for Pb-free reflow per J-STD-020. Peak temperature tolerance is 260 °C for 10 seconds; standard IPC/JEDEC profiles (e.g., SnAgCu ramp-to-spike) apply without derating or special process adjustments.
