Product details
Overview
VESD16A2-03GHG3-08 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 VESD16A2-03GHG3-08 datasheet, VESD16A2-03GHG3-08 pinout, VESD16A2-03GHG3-08 application, or VESD16A2-03GHG3-08 equivalent, key selection criteria include clamping voltage at 3.6 A (25.3–28 V), 21–33 pF capacitance at 0 V, dynamic resistance of 0.53 Ω, AEC-Q101 qualification status, and SOT-323 footprint compatibility with high-density PCB layouts.
Technical Context
This device implements two independent unidirectional TVS diodes in a single SOT-323 package, each configured as a cathode-anode-cathode (CAK) structure with shared cathode terminal (Pin 3), enabling bidirectional protection across two signal lines referenced to common ground.
It operates within -55 °C to +150 °C junction temperature range, supports lead-free reflow up to 260 °C peak, and meets MSL level 1 per J-STD-020 - eliminating bake requirements prior to assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 16 V - maximum continuous working voltage before leakage exceeds 0.1 µA; defines safe operating margin for 12 V automotive bus signals. |
| Reverse Clamping Voltage | 25.3–28 V at 3.6 A (8/20 µs) - limits transient voltage seen by downstream ICs during ESD events. |
| Capacitance | 21–33 pF at 0 V, 1 MHz - low enough to avoid signal integrity degradation on USB 2.0 or CAN FD data lines. |
| ESD Immunity | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - exceeds Level 4 industrial and automotive ESD robustness requirements. |
| Peak Pulse Power | 100 W (8/20 µs) - sustains high-energy transients without thermal failure under standardized surge conditions. |
| Dynamic Resistance | 0.53 Ω (TLP, 100 ns) - ensures fast, low-impedance clamping response to sub-nanosecond ESD rise times. |
Pinout & Package
SOT-323 package: 3-pin surface-mount plastic case (D01-type mold compound, UL 94 V-0, 5.2 mg weight), compatible with standard 0.65 mm pitch reflow processes and AOI inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Channel 1 | Input node for first protected line; connects to signal trace upstream of IC input. |
| Pin 2 | Anode of Channel 2 | Input node for second protected line; electrically isolated from Pin 1, shares common cathode. |
| Pin 3 | Common Cathode | Ground reference for both channels; must connect to low-impedance system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional Dual-Channel Protection | Two independent anode-input paths sharing one cathode enable compact protection of differential or separate signal pairs without cross-talk. |
| AEC-Q101 Qualified Variant Available | Specific part suffix 'H' denotes automotive-grade qualification - verified for temperature cycling, HTRB, and ESD stress per AEC standard. |
| Low Capacitance (21–33 pF) | Minimizes signal distortion and insertion loss on high-speed interfaces such as LVDS or FlexRay up to 100 Mbps. |
| Sn (e3) Lead Plating | RoHS-compliant matte tin termination enables reliable solder wetting and compatibility with standard vision-based AOI systems. |
| MSL Level 1 Rating | Zero floor life limitation - parts can be stored indefinitely at ≤30 °C/60 % RH without baking before reflow. |
Applications
| Automotive Infotainment Display Interface | Industrial CAN FD Bus Node |
|---|---|
|
Use Scenario: Protecting MIPI DSI or RGB parallel video lines between head unit MCU and TFT display module against ESD during service or connector mating. IC Role / Device Role / Timing Role: Front-end transient suppressor placed directly at board edge connector, clamping fast-rising ESD pulses before they reach display driver IC inputs. Use Value: 21–33 pF capacitance avoids pixel clock jitter; 30 kV immunity prevents display lockup or artifacting in vehicle cabin environments. |
Use Scenario: Safeguarding CAN FD transceiver pins (CANH/CANL) in programmable logic controller (PLC) field I/O modules exposed to maintenance personnel handling. IC Role / Device Role / Timing Role: Point-of-entry protection on differential bus lines, shunting ESD energy to chassis ground while preserving common-mode noise rejection. Use Value: 16 V VRWM aligns with CAN FD 12 V supply rails; 25.3–28 V clamping ensures transceiver remains within absolute max ratings during ±30 kV contact discharge. |
| Medical Patient Monitor Data Port | Consumer USB 2.0 OTG Connector |
|
Use Scenario: Shielding RS-485 or UART lines connecting bedside sensor hub to central monitor against electrostatic discharge from clinical staff gloves. IC Role / Device Role / Timing Role: Low-capacitance guard on bidirectional serial interface, placed adjacent to connector to minimize stub length and preserve signal rise time. Use Value: 0.53 Ω dynamic resistance delivers sub-100 ps response; MSL Level 1 supports long-term inventory storage in regulated medical device supply chains. |
Use Scenario: ESD hardening of USB 2.0 D+/D− lines on portable speaker or power bank where users frequently plug/unplug cables in dry environments. IC Role / Device Role / Timing Role: Dual-channel clamp integrated into USB receptacle footprint, with shared cathode reducing ground loop inductance versus discrete diodes. Use Value: 3.6 A IPPM rating handles multiple IEC 61000-4-2 pulses without parametric shift; Sn (e3) plating ensures consistent solder joint reliability across high-volume consumer assembly. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J16A-Q | Single-channel, SMA package (larger footprint), 16 V VRWM, 30 kV ESD, but 6.5 A IPPM and 120 W PPP - higher surge capacity but double the board area. | Best suited for lower-density designs where space is not constrained and higher single-line surge margin is required. | Select when protecting only one line or when legacy SMA layout exists; not suitable for dual-line space-constrained routing. |
| TPD2E001DRYR | Two-channel unidirectional, SOT-553 package, 5 V VRWM, 15 kV ESD, 12 pF - lower voltage rating and reduced ESD level, but lower capacitance. | Targeted at 3.3 V logic interfaces (e.g., I²C, GPIO) rather than 12–16 V automotive or industrial buses. | Choose for low-voltage digital I/O protection where 16 V standoff is unnecessary; incompatible with 12 V supply-referenced systems. |
Compared with SMA6J16A-Q and TPD2E001DRYR, VESD16A2-03GHG3-08 uniquely balances dual-line protection, 16 V standoff, 30 kV ESD immunity, and SOT-323 miniaturization - making it optimal for space-limited 12 V automotive or industrial data links requiring AEC-Q101 readiness.

FAQ
What is the maximum operating temperature range for VESD16A2-03GHG3-08?
VESD16A2-03GHG3-08 has a junction temperature range of -55 °C to +150 °C and a storage temperature range of -55 °C to +150 °C. This wide thermal envelope supports deployment in under-hood automotive modules, industrial motor drives, and outdoor equipment where ambient temperatures exceed 105 °C.
Does VESD16A2-03GHG3-08 meet AEC-Q101 qualification?
VESD16A2-03GHG3-08 itself carries no 'H' suffix and is not AEC-Q101 qualified; however, the variant VESD16A2-03GHG3A08 (with 'H' and 'A') is explicitly listed in Vishay's ordering table as AEC-Q101 qualified. Always verify the full part number suffix when specifying for automotive applications.
How does the pin configuration of VESD16A2-03GHG3-08 support dual-line protection?
VESD16A2-03GHG3-08 uses a 3-pin SOT-323 layout: Pin 1 and Pin 2 serve as independent anodes for two signal lines, while Pin 3 is the common cathode tied to system ground. This CAK topology allows simultaneous protection of two unidirectional lines with minimal parasitic inductance and no inter-channel coupling.
What is the typical capacitance of VESD16A2-03GHG3-08 and why does it matter?
VESD16A2-03GHG3-08 exhibits 21–33 pF capacitance at 0 V and 1 MHz. This low value prevents excessive signal attenuation and timing skew on high-speed data lines like USB 2.0 or CAN FD, ensuring bit error rates remain within specification while maintaining robust ESD suppression.
Can VESD16A2-03GHG3-08 be used in place of VESD12A2-03G or VESD26A2-03G?
No - VESD16A2-03GHG3-08 is not interchangeable with VESD12A2-03G (12 V VRWM) or VESD26A2-03G (26 V VRWM) due to different reverse stand-off voltages and clamping characteristics. Substitution requires verifying that 16 V VRWM matches the protected circuit's operating voltage and that 25.3–28 V clamping stays within downstream IC absolute maximum ratings.
