Product details
Overview
VLIN1626-02GHE3-18 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 VLIN1626-02GHE3-18 datasheet, VLIN1626-02GHE3-18 pinout, VLIN1626-02GHE3-18 application, or VLIN1626-02GHE3-18 equivalent, this device serves as a dedicated, AEC-Q101-qualified transient suppressor for unidirectional LIN data lines requiring minimal parasitic capacitance and high reliability under harsh automotive voltage transients.
Technical Context
The VLIN1626-02GHE3-18 implements a dual-zener architecture to provide symmetrical bidirectional clamping across its two terminals, supporting both LIN bus polarity configurations. Its breakdown voltages are specified at 17.1–20.3 V (1→2) and 28–32 V (2→1), ensuring precise voltage limiting during ESD events without false triggering during normal 12 V automotive operation.
Designed for integration directly on LIN transceiver I/O paths, it operates over –55 °C to +150 °C junction temperature and complies with J-STD-020 MSL Level 1 soldering conditions (peak 260 °C). Its SOD-323 package enables compact placement adjacent to connectors or ICs while maintaining <19 pF capacitance critical for 20.2 kbps LIN timing compliance.
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 | Lower clamping voltage (12.5 V @ 1 A), higher capacitance (35 pF), same SOD-323 package | Better for low-voltage logic lines; unsuitable for LIN due to excessive capacitance-induced timing skew | Select only if protecting sub-5 V digital signals - not recommended for LIN-Bus |
| TPD2E001DRYR | Single-line, 12 V stand-off, 12 pF capacitance, but not AEC-Q101 qualified | Limited to non-automotive industrial LIN gateways where qualification is not mandated | Use where cost sensitivity outweighs automotive qualification requirements |
Compared with ESDALC6V1-1U2 and TPD2E001DRYR, the VLIN1626-02GHE3-18 uniquely balances LIN-specific voltage thresholds, sub-19 pF capacitance, and full AEC-Q101 qualification - making it the only drop-in solution for production automotive LIN nodes requiring zero design compromises.

FAQ
What is the primary circuit role of the VLIN1626-02GHE3-18 in a LIN-Bus system?
The VLIN1626-02GHE3-18 functions as a bidirectional transient voltage suppressor placed directly on the LIN data line to clamp ESD and surge events before they reach the LIN transceiver. Its 16 V / 26.5 V stand-off voltages match LIN bus operating margins, and its <19 pF capacitance ensures no measurable impact on the 20.2 kbps data rate. The VLIN1626-02GHE3-18 is designed for placement between the transceiver output and connector, providing first-line defense without altering signal timing.
Does the VLIN1626-02GHE3-18 meet AEC-Q101 requirements for automotive use?
Yes, the VLIN1626-02GHE3-18 is explicitly qualified to AEC-Q101 Rev D standards, including stress tests for temperature cycling, high-temperature operating life, and human-body-model ESD (>8 kV). This qualification is documented in Vishay's official specification document 85902 and confirmed in the ordering code suffix "H" (AEC-Q101 qualified). The VLIN1626-02GHE3-18 is approved for under-hood and cabin applications where extended temperature operation (–55 °C to +150 °C) and long-term reliability are mandatory.
What is the maximum clamping voltage of the VLIN1626-02GHE3-18 during an ESD event?
The VLIN1626-02GHE3-18 clamps to ≤25 V (typical 22 V) at 1 A and ≤33 V (typical 29 V) at 6 A for pin 1→2 polarity, and ≤40 V (typical 32 V) at 1 A and ≤50 V (typical 39 V) at 4 A for pin 2→1 polarity, per IEC 61000-4-5 8/20 μs waveform testing. These values ensure downstream LIN transceivers remain within absolute maximum ratings during real-world surge events. The VLIN1626-02GHE3-18 maintains these clamping levels across its full operating temperature range.
Can the VLIN1626-02GHE3-18 be used on a 5 V logic line instead of a LIN bus?
No - the VLIN1626-02GHE3-18 is not suitable for 5 V logic protection due to its 16 V reverse stand-off voltage, which would allow destructive overvoltage to reach the protected IC before clamping activates. Its voltage thresholds are intentionally set for 12 V automotive LIN systems. For 5 V applications, devices like the ESDALC6V1-1U2 (6.1 V stand-off) are appropriate. The VLIN1626-02GHE3-18 must only be applied where its 16 V / 26.5 V asymmetry matches the target bus architecture.
What packaging and reel configuration does the VLIN1626-02GHE3-18 ship in?
The VLIN1626-02GHE3-18 ships in SOD-323 package on 8 mm tape, with 10,000 units per 13-inch reel (ordering code suffix "18"). It uses e3 tin-plated terminations and meets RoHS requirements. The carrier tape orientation places the cathode bar toward the sprocket holes, and the device is MSL Level 1 - compatible with standard Pb-free reflow profiles up to 260 °C peak. The VLIN1626-02GHE3-18 reel labeling includes full traceability per Vishay's quality documentation.
