Product details
Overview
VLIN2626-02GHE3-18 from Vishay Semiconductors is a single-line, low-capacitance ESD-protection diode designed for LIN-bus communication systems. It features a reverse stand-off voltage of 26.5 V, clamping voltage ≤40 V at 1 A (8/20 µs), load capacitance <16 pF, leakage current <0.05 µA, and ±30 kV IEC 61000-4-2 ESD immunity - enabling robust transient suppression in automotive body electronics.
For engineers reviewing the VLIN2626-02GHE3-18 datasheet, VLIN2626-02GHE3-18 pinout, VLIN2626-02GHE3-18 application, or VLIN2626-02GHE3-18 equivalent, key selection criteria include its AEC-Q101 qualification, SOD-323 footprint compatibility, LIN-bus-specific voltage thresholds, and sub-16 pF capacitance critical for maintaining signal integrity on 19.2–20 kbps serial buses.
Technical Context
The VLIN2626-02GHE3-18 implements a unidirectional TVS structure optimized for LIN physical layer protection, with a breakdown voltage of 28–32 V and clamping performance validated per IEC 61000-4-5 (8/20 µs, 4 A peak pulse). Its e3 tin-plated terminations and MSL level 1 rating support lead-free reflow up to 260 °C.
It operates across –55 °C to +150 °C junction temperature and meets ISO 10605 (±30 kV) and AEC-Q101 H3B-class (>8 kV HBM) requirements - confirming suitability for under-hood and interior automotive modules where LIN bus nodes interface with microcontrollers and transceivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 26.5 V - ensures no conduction during normal LIN-bus operation (12 V nominal + transients) |
| Clamping Voltage (1 A) | ≤40 V - limits voltage seen by downstream LIN transceiver during ESD events |
| Load Capacitance | 13.5–16 pF - preserves signal edge rate and timing margin on 20 kbps LIN signals |
| Leakage Current | <0.05 µA at 26.5 V - avoids parasitic loading of LIN pull-up/pull-down networks |
| ESD Rating | ±30 kV contact/air (IEC 61000-4-2) - exceeds automotive OEM ESD test requirements |
| AEC-Q101 Qualification | H3B-class (>8 kV HBM) - certified for automotive production use without additional qualification |
| Package | SOD-323 - 2.5 × 1.25 mm footprint compatible with high-density PCB layouts |
Pinout & Package

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 VRWM (5.5 V); higher CD (25 pF); bidirectional | Designed for CAN/LIN mixed-signal nodes; not rated for 26.5 V working voltage | Select only if protecting lower-voltage interfaces; unsuitable for direct LIN-bus replacement |
| TPD2E001DRYR | VRWM = 5.5 V; CD = 11 pF; dual-line; non-AEC-Q101 | Targeted at consumer USB/IO protection; lacks automotive qualification and LIN voltage range | Not recommended for automotive LIN; consider only for non-automotive 5 V logic-level protection |
Compared with ESDALC6V1-1U2 and TPD2E001DRYR, the VLIN2626-02GHE3-18 uniquely combines 26.5 V stand-off, AEC-Q101 H3B certification, and sub-16 pF capacitance - making it the only qualified solution for production LIN-bus nodes requiring both voltage headroom and signal fidelity.

FAQ
What is the maximum operating temperature for VLIN2626-02GHE3-18?
The VLIN2626-02GHE3-18 has a specified junction temperature range of –55 °C to +150 °C, fully supporting under-hood automotive applications. This rating is verified per AEC-Q101 stress tests and confirmed in the official Vishay datasheet (Doc. #85915, Rev. 1.6). Thermal design must ensure the die temperature stays within this limit during peak LIN bus fault conditions.
Is VLIN2626-02GHE3-18 pin-compatible with other SOD-323 ESD diodes?
Yes, VLIN2626-02GHE3-18 uses the standard SOD-323 package with anode (pin 1) and cathode (pin 2) orientation matching JEDEC MO-203AA. Its pinout is mechanically identical to other SOD-323 diodes like SMAJ5.0A or P6SMB5.0A, but electrical characteristics - especially 26.5 V VRWM and LIN-specific clamping - are unique to VLIN2626-02GHE3-18.
Does VLIN2626-02GHE3-18 support bidirectional ESD protection?
No, VLIN2626-02GHE3-18 is a unidirectional ESD protection diode, configured for connection between LIN bus line and ground. Its electrical specifications - including reverse stand-off voltage (26.5 V) and breakdown threshold (28–32 V) - are defined only for reverse-bias operation. Bidirectional variants are not offered in this part number.
What is the tape-and-reel packaging configuration for VLIN2626-02GHE3-18?
VLIN2626-02GHE3-18 ships in 8 mm carrier tape on 13-inch reels containing 10,000 units (ordering code ending in "18"). The device is oriented with cathode bar facing the sprocket holes, per Vishay's SOD-323 tape specification (Doc. S8-V-3717.07-002). Reel ID and quantity are marked on the box label per standard Vishay packaging protocol.
Can VLIN2626-02GHE3-18 be used on CAN bus lines?
No - VLIN2626-02GHE3-18 is specifically characterized and qualified for LIN-bus voltage ranges (max 26.5 V working), not CAN's 5 V differential signaling. Its clamping behavior, capacitance profile, and AEC-Q101 test focus are optimized for LIN's single-wire topology and 20 kbps data rate. Using it on CAN may result in signal integrity loss or insufficient protection margin.
