Product details
Overview
VESD16A2-03G-G3-08 from Vishay Semiconductors is a dual-line unidirectional ESD-protection diode array in SOT-323 package, rated for 16 V reverse stand-off voltage, 30 kV IEC 61000-4-2 contact/air discharge immunity, and 3.6 A peak pulse current (8/20 μs), deployed in automotive infotainment data lines.
For engineers reviewing the VESD16A2-03G-G3-08 datasheet, VESD16A2-03G-G3-08 pinout, VESD16A2-03G-G3-08 application, or VESD16A2-03G-G3-08 equivalent, this page delivers verified electrical specs, package dimensions, clamping behavior, thermal limits, and real-world ESD protection context for high-reliability PCB design.
Technical Context
This device implements two independent unidirectional TVS diodes in a single SOT-323 package, with common cathode configuration (Pin 3 = cathode, Pins 1 & 2 = anodes). It operates within -55 °C to +150 °C junction temperature range and meets AEC-Q101 qualification when ordered with 'H' suffix - though VESD16A2-03G-G3-08 uses standard 'G3' packaging code without AEC-Q101 marking.
The diode pair provides low-capacitance (27 pF typical at 0 V) transient suppression with 25.3 V typical reverse clamping voltage at 3.6 A, 8/20 μs pulse, and dynamic resistance of 0.53 Ω - enabling fast response to ESD events while minimizing signal distortion on 16 V-rated interfaces like USB 2.0 or CAN FD data lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 16 V - maximum continuous DC or RMS voltage the diode blocks before entering breakdown; sets upper limit for protected line operating voltage. |
| Reverse Clamping Voltage | 25.3 V typical at 3.6 A, 8/20 μs - peak voltage seen across protected line during worst-case surge; ensures downstream ICs remain below absolute max ratings. |
| Capacitance | 27 pF typical at 0 V, 1 MHz - low enough to avoid signal integrity degradation on high-speed interfaces up to ~200 Mbps. |
| ESD Immunity | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - exceeds Level 4 industrial and automotive ESD requirements for exposed connectors. |
| Peak Pulse Current | 3.6 A (8/20 μs) - surge-handling capability aligned with IEC 61000-4-5 waveform; defines robustness against lightning-induced transients. |
| Junction Temperature Range | -55 °C to +150 °C - supports operation in under-hood automotive environments and industrial control enclosures. |
Pinout & Package
SOT-323 package: 3-pin surface-mount plastic case (2.2 mm × 1.35 mm × 0.9 mm), lead-free Sn (e3) plating, MSL level 1, compatible with standard reflow profiles (peak 260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Channel 1 | Connects to first protected signal line (e.g., USB D+); conducts during negative ESD event toward common cathode. |
| Pin 2 | Anode of Channel 2 | Connects to second protected signal line (e.g., USB D−); independent conduction path, same cathode reference. |
| Pin 3 | Common Cathode | Shared return node tied to system ground or low-impedance reference plane; critical for low-inductance layout. |
Key Features
| Feature | Design Value |
|---|---|
| Dual unidirectional protection | Two independent anode-to-cathode paths enable separate protection of bidirectional data lines without polarity inversion concerns. |
| Low dynamic resistance | 0.53 Ω typical enables rapid voltage clamping and minimizes energy dissipation during transient events. |
| AEC-Q101 qualified option | Available as VESD16A2-03GHG3A08 (with 'H' suffix) for automotive applications requiring stress-tested reliability. |
| Compact SOT-323 footprint | Reduces PCB area by >50% vs. SOIC-8 alternatives while maintaining full dual-line ESD capability. |
| Lead (Pb)-free termination | Sn (e3) plating ensures RoHS compliance and compatibility with automated optical inspection (AOI) systems. |
Applications
| Automotive Infotainment Interface | Industrial USB 2.0 Port |
|---|---|
Use Scenario: Protecting USB 2.0 differential pair (D+/D−) on head unit rear-panel connectors exposed to service technician handling. IC Role / Device Role: Unidirectional ESD clamp limiting transient voltage to ≤28 V during ±30 kV contact discharge. Use Value: Prevents latch-up or gate oxide damage in USB transceivers while maintaining <27 pF loading for 480 Mbps signaling integrity. |
Use Scenario: Safeguarding field-service USB ports on PLC programming interfaces subject to repeated plug/unplug cycles in factory environments. IC Role / Device Role: Dual-channel transient voltage suppressor with common cathode grounding to chassis earth. Use Value: Eliminates need for discrete diodes per line, reducing BOM count and layout complexity without sacrificing clamping performance. |
| Automotive CAN FD Data Line | Medical Sensor Interface |
Use Scenario: ESD hardening of CAN FD high-speed bus (CAN_H/CAN_L) in ADAS domain controllers where 16 V supply rails are present. IC Role / Device Role: Two-channel unidirectional protector with 16 V VRWM matching nominal CAN FD bias voltage. Use Value: Ensures clamping occurs only during overvoltage events - no leakage or loading impact on normal 0–5 V CAN signal swing. |
Use Scenario: Shielding analog sensor inputs (e.g., thermistor or strain gauge bridges) in portable diagnostic devices from electrostatic discharge during clinical handling. IC Role / Device Role: Low-capacitance dual TVS suppressing transients before precision ADC front-end stages. Use Value: 21–33 pF capacitance avoids gain/phase error in <10 kHz sensor bandwidths while delivering ±30 kV system-level ESD immunity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J16A | Single-channel SMA package; 16 V VRWM, 32.6 V VC @ 3.5 A; higher capacitance (~500 pF) | Requires two devices for dual-line protection; unsuitable for high-speed data due to excessive capacitance | Select only for low-frequency power/signal lines where space allows discrete placement and speed is not critical. |
| TPD2E001DRSR | 2-channel unidirectional, 5 V VRWM, 12.5 V VC @ 1 A, 12 pF; smaller X2SON package | Lower voltage rating limits use to 3.3 V/5 V systems; insufficient for 16 V automotive rails | Prefer for USB/MIPI interfaces in consumer electronics; not suitable as drop-in replacement for 16 V applications. |
Compared with SMA6J16A and TPD2E001DRSR, VESD16A2-03G-G3-08 uniquely balances 16 V working voltage, dual-channel integration, 27 pF capacitance, and ±30 kV ESD immunity in a miniature SOT-323 - making it optimal for space-constrained, high-voltage data line protection where both channel independence and low parasitic loading are required.

FAQ
What is the maximum operating voltage supported by VESD16A2-03G-G3-08?
VESD16A2-03G-G3-08 has a reverse stand-off voltage (VRWM) of 16 V, meaning it reliably blocks voltages up to 16 V in normal operation. It begins clamping above ~17 V (VBR min = 17 V), making it suitable for circuits powered from nominal 12 V or 16 V rails such as automotive body control modules or industrial 24 V systems with local 16 V regulation.
Does VESD16A2-03G-G3-08 meet AEC-Q101 qualification?
VESD16A2-03G-G3-08 does not carry AEC-Q101 qualification - that version is designated VESD16A2-03GHG3A08 (with 'H' in the environmental code). The 'G3-08' suffix indicates standard commercial-grade packaging: Pb-free Sn plating, 3 k per 7″ reel, and MSL level 1 moisture sensitivity.
How does the clamping performance of VESD16A2-03G-G3-08 compare to lower-voltage variants like VESD05A2-03G?
VESD16A2-03G-G3-08 clamps at 25.3 V (typical) under 3.6 A, 8/20 μs surge, whereas VESD05A2-03G clamps at 10.3 V (typical) under 8.7 A. The higher VRWM device trades peak current capacity for higher voltage tolerance - essential when protecting 16 V logic or analog rails where lower-clamp devices would conduct prematurely.
Can VESD16A2-03G-G3-08 be used for bidirectional signal lines like RS-485?
No - VESD16A2-03G-G3-08 is unidirectional (anode-to-cathode only). For bidirectional lines such as RS-485, a symmetric dual-diode configuration or dedicated bidirectional ESD array (e.g., VESD16A2-03B-G3-08) is required. Using this part on bidirectional lines risks forward conduction during normal signal swings.
What is the thermal derating behavior of VESD16A2-03G-G3-08 above 25 °C ambient?
VESD16A2-03G-G3-08 maintains full absolute maximum ratings (-55 °C to +150 °C junction temperature) across its operating range. Its peak pulse power (100 W) and clamping voltage are specified at Tamb = 25 °C; no derating is required for junction temperatures up to 150 °C, though PCB copper area and thermal vias should ensure TJ stays within limits during repetitive surges.
