Product details
Overview
VLIN1626-02G-E3-08 from Vishay Semiconductors is a single-line, low-capacitance ESD-protection diode optimized for LIN-Bus communication interfaces, featuring bidirectional clamping with reverse stand-off voltages of 16 V (pin 1→2) and 26.5 V (pin 2→1), <19 pF capacitance at 0 V, <0.05 μA leakage, and ±30 kV IEC 61000-4-2 ESD immunity - deployed in automotive body control modules and sensor nodes.
For engineers reviewing the VLIN1626-02G-E3-08 datasheet, VLIN1626-02G-E3-08 pinout, VLIN1626-02G-E3-08 application, or VLIN1626-02G-E3-08 equivalent, key selection criteria include bidirectional voltage asymmetry, AEC-Q101 qualification, SOD-323 footprint compatibility, and sub-20 pF load capacitance for high-speed LIN transceiver signal integrity.
Technical Context
This device implements a monolithic, bidirectional TVS structure with asymmetric breakdown thresholds (17.1–20.3 V reverse, 28–32 V forward), enabling robust protection of LIN bus lines against transient surges while preserving signal fidelity. Its low 15.5–19 pF capacitance minimizes signal distortion on 20.2 kbps LIN waveforms.
The SOD-323 package supports reflow soldering per J-STD-020 MSL level 1 (peak 260 °C), and the e3 tin-plated terminations ensure RoHS compliance and solderability. It is rated for continuous operation from −55 °C to +150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protection topology | Bidirectional asymmetric TVS: protects both LIN line polarity directions with distinct clamping thresholds |
| Reverse stand-off voltage (VRWM) | 16 V (pin 1→2), 26.5 V (pin 2→1): defines max DC operating voltage before leakage rises significantly |
| Clamping voltage (VC) | 22–25 V @ 1 A (1→2), 32–40 V @ 1 A (2→1): limits transient voltage seen by downstream LIN transceiver |
| Capacitance (CD) | 15.5–19 pF @ 0 V, 1 MHz: ensures minimal loading on LIN's 20.2 kbps NRZ signal without edge degradation |
| ESD rating | ±30 kV contact/air per IEC 61000-4-2: exceeds automotive OEM requirements for dashboard and door module ESD robustness |
| AEC-Q101 qualification | Qualified per H3B human body model (>8 kV): validated for under-hood and cabin automotive environments |
Pinout & Package
SOD-323 surface-mount package (2.85 × 1.60 × 1.15 mm), cathode-marked with bar on pin 1 side, MSL level 1, UL 94 V-0 molding compound, 4 mg unit weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode for reverse-direction clamping (2→1 path) | Connects to LIN bus line; forms low-impedance shunt to ground during positive transients on pin 2 |
| Pin 2 | Cathode for forward-direction clamping (1→2 path) | Connects to ground or protected IC reference; provides return path for negative transients on pin 1 |
Key Features
| Feature | Design Value |
|---|---|
| Asymmetric voltage rating | Enables dedicated protection of LIN's unidirectional data line (dominant/recessive logic) without over-clamping |
| Sub-20 pF capacitance | Maintains LIN signal rise/fall time integrity (<10% distortion at 20.2 kbps) across full temperature range |
| e3 tin plating | Ensures lead-free solder joint reliability and eliminates whisker risk in long-life automotive applications |
| MSL level 1 rating | Allows unlimited floor life and standard reflow without baking, reducing manufacturing overhead |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD-protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDALC6V1-1U2 | Unidirectional, 6.1 V VRWM, 12 pF typical capacitance, ±30 kV ESD | Designed for 5 V logic rails; not suitable for LIN's 12 V supply-referenced bus | Select only if protecting low-voltage MCU GPIOs-not LIN bus lines |
| SP1003-01UTG | Bidirectional, 12 V VRWM (symmetrical), 15 pF, ±30 kV ESD, AEC-Q101 qualified | Lacks asymmetric voltage rating; clamps both polarities at ~12 V, risking false triggering on LIN dominant state | Acceptable for non-critical LIN segments where bus voltage margin is >3 V above VRWM |
Compared with ESDALC6V1-1U2 and SP1003-01UTG, VLIN1626-02G-E3-08 uniquely delivers asymmetric clamping aligned to LIN's 12 V nominal bus and 27 V load-dump tolerance, ensuring protection without interfering with valid recessive/dominant voltage levels.

FAQ
What is the primary circuit role of VLIN1626-02G-E3-08 in a LIN-Bus system?
The VLIN1626-02G-E3-08 serves as a bidirectional transient voltage suppressor placed directly on the LIN bus line between the connector and transceiver. It clamps ESD and surge events-such as ±30 kV contact discharge-while maintaining signal integrity through its <19 pF capacitance and asymmetric 16 V / 26.5 V stand-off ratings. This ensures the VLIN1626-02G-E3-08 protects LIN communication without distorting the 20.2 kbps NRZ waveform or interfering with dominant/recessive logic states.
Does VLIN1626-02G-E3-08 support AEC-Q101 qualification, and what does that cover?
Yes, VLIN1626-02G-E3-08 is AEC-Q101 qualified, specifically meeting the H3B human body model class (>8 kV). This qualification validates its robustness against electrostatic discharge in automotive environments, including under-hood and cabin locations. The VLIN1626-02G-E3-08 has undergone temperature cycling, humidity bias, mechanical shock, and high-temperature operating life testing per AEC-Q101 Rev D, confirming suitability for automotive production use.
What is the significance of the asymmetric voltage rating (16 V / 26.5 V) in VLIN1626-02G-E3-08?
The asymmetric voltage rating reflects the VLIN1626-02G-E3-08's design for LIN's unidirectional bus architecture: 16 V stand-off on pin 1→2 aligns with LIN's recessive state (near battery voltage), while 26.5 V on pin 2→1 accommodates load-dump transients and dominant-state overshoot. This prevents false triggering during normal operation while ensuring clamping occurs only during actual threats-making the VLIN1626-02G-E3-08 functionally distinct from symmetrical TVS diodes.
Can VLIN1626-02G-E3-08 be used in non-automotive applications such as industrial LIN networks?
Yes, VLIN1626-02G-E3-08 is suitable for industrial LIN implementations where ESD robustness, low capacitance, and wide temperature operation (−55 °C to +150 °C) are required. Its SOD-323 footprint and MSL level 1 rating simplify integration into industrial control panels or building automation nodes. While AEC-Q101 qualification is automotive-focused, the underlying reliability and electrical specs of VLIN1626-02G-E3-08 make it equally effective in harsh industrial settings.
What are the soldering and packaging specifications for VLIN1626-02G-E3-08?
VLIN1626-02G-E3-08 uses e3 tin-plated terminations and conforms to J-STD-020 MSL level 1, allowing unlimited floor life and peak reflow temperatures up to 260 °C. It ships in 8 mm carrier tape: 3,000 units per 7-inch reel (E3-08) or 10,000 per 13-inch reel (E3-18). The SOD-323 package dimensions are 2.85 × 1.60 × 1.15 mm, with cathode marking on pin 1 side-fully compatible with standard pick-and-place and reflow processes.
