Product details
Overview
VLIN1626-02GHE3-08 from Vishay Semiconductors is a single-line, low-capacitance ESD protection diode optimized for LIN-bus communication interfaces. It features bidirectional clamping with reverse stand-off voltages of 16 V (pin 1→2) and 26.5 V (pin 2→1), <19 pF load capacitance, <0.05 μA leakage current, and ±30 kV IEC 61000-4-2 ESD immunity - enabling robust signal integrity in automotive body electronics.
For engineers reviewing the VLIN1626-02GHE3-08 datasheet, VLIN1626-02GHE3-08 pinout, VLIN1626-02GHE3-08 application, or VLIN1626-02GHE3-08 equivalent, key selection criteria include bidirectional clamping voltage asymmetry, AEC-Q101 qualification status, SOD-323 footprint compatibility, and LIN-bus-specific transient suppression performance under 12 V/24 V system bias conditions.
Technical Context
This device implements a monolithic silicon avalanche diode structure configured as an asymmetric bidirectional TVS, where pin 1 serves as cathode for the 16 V path and pin 2 as cathode for the 26.5 V path. Its design enables simultaneous protection of LIN transceiver I/O against both positive and negative transients without external polarity constraints.
It operates within -55 °C to +150 °C junction temperature range and meets AEC-Q101 stress requirements including HBM >8 kV. The SOD-323 package supports reflow soldering per J-STD-020 MSL level 1, with peak temperature tolerance up to 260 °C.
Key Specifications

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 stand-off; lower capacitance (8 pF), no AEC-Q101 qualification | Requires external bias network for LIN bidirectional protection; limited to non-automotive or pre-qualification designs | Choose when ultra-low capacitance is prioritized over automotive qualification and system-level simplicity |
| SP1006-01WTG | Bidirectional, 12 V stand-off; higher capacitance (35 pF); AEC-Q101 qualified | Clamps at lower voltage but adds significant signal loading - may distort LIN edges above 10 kbps | Acceptable only if LIN speed is reduced or if board layout allows series impedance tuning to compensate |
Compared with ESDALC6V1-1U2 and SP1006-01WTG, VLIN1626-02GHE3-08 uniquely combines LIN-specific asymmetric clamping, automotive qualification, and sub-19 pF capacitance - eliminating need for external components while ensuring full-speed 19.2 kbps operation and production-grade reliability.

FAQ
What is the primary function of the VLIN1626-02GHE3-08 in a LIN-bus system?
The VLIN1626-02GHE3-08 functions as an asymmetric bidirectional ESD protection diode for LIN bus lines, providing dedicated 16 V and 26.5 V reverse stand-off paths to safeguard transceivers from electrostatic discharge and fast transients. Its design eliminates the need for external biasing while maintaining signal integrity - a critical requirement for reliable VLIN1626-02GHE3-08 deployment in automotive LIN networks.
Does the VLIN1626-02GHE3-08 meet AEC-Q101 qualification requirements?
Yes, the VLIN1626-02GHE3-08 is AEC-Q101 qualified per revision D, including human body model (HBM) Class H3B (>8 kV). This qualification confirms its suitability for automotive production applications such as body control modules and door actuators where long-term reliability under thermal and mechanical stress is mandatory - a key differentiator of the VLIN1626-02GHE3-08 versus generic ESD diodes.
What is the maximum clamping voltage of the VLIN1626-02GHE3-08 under surge conditions?
The VLIN1626-02GHE3-08 clamps to ≤25 V (pin 1→2) and ≤40 V (pin 2→1) at specified peak pulse currents of 6 A and 4 A respectively, per IEC 61000-4-5 8/20 μs waveform. These values ensure LIN transceivers remain within absolute maximum ratings during surge events - a verified performance metric documented in the VLIN1626-02GHE3-08 datasheet Figure 6 and Table "Reverse clamping voltage".
Can the VLIN1626-02GHE3-08 be used in 24 V commercial vehicle LIN systems?
Yes, the VLIN1626-02GHE3-08 supports 24 V systems via its 26.5 V reverse stand-off voltage on the pin 2→1 path, which provides sufficient margin above typical 24 V nominal rails (up to ~28 V during load dump). Its -55 °C to +150 °C operating range and AEC-Q101 qualification further validate VLIN1626-02GHE3-08 use in heavy-duty truck and bus LIN applications.
How does the capacitance of the VLIN1626-02GHE3-08 affect LIN signal integrity?
The VLIN1626-02GHE3-08 exhibits 15.5–19 pF capacitance at 0 V bias, measured at 1 MHz - low enough to preserve LIN's 19.2 kbps bit rate and maintain rise/fall time compliance (<1 μs). This capacitance value was characterized across temperature and voltage in the VLIN1626-02GHE3-08 datasheet Figure 3 and confirmed to avoid signal distortion or timing jitter in production LIN nodes.
