Product details
Overview
VLIN2626-02G-E3-18 from Vishay Semiconductors is a single-line, low-capacitance ESD protection diode designed for LIN bus signal lines in automotive and industrial control systems. It features a reverse stand-off voltage of 26.5 V, clamping voltage ≤40 V at 1 A, leakage current <0.05 μA, load capacitance <16 pF, and ±30 kV IEC 61000-4-2 contact/air discharge rating.
For engineers reviewing the VLIN2626-02G-E3-18 datasheet, VLIN2626-02G-E3-18 pinout, VLIN2626-02G-E3-18 application, or VLIN2626-02G-E3-18 equivalent, key selection criteria include LIN-bus compatibility, SOD-323 footprint constraints, sub-16 pF signal-line loading, AEC-Q101 qualification status, and 26.5 V working voltage margin for 12 V automotive systems.
Technical Context
The VLIN2626-02G-E3-18 implements a unidirectional TVS structure optimized for bidirectional LIN bus signaling with asymmetric clamping behavior: it conducts during negative transients via forward conduction and during positive transients via reverse avalanche breakdown. Its 26.5 V VRWM aligns with LIN physical layer voltage limits while maintaining >1.5 V margin below typical battery surge peaks.
Designed for placement directly at connector interfaces, the device delivers 4 A peak pulse current (8/20 μs) and 200 W peak pulse power per IEC 61000-4-5, with clamping voltage tightly bounded at 39–50 V under full 4 A stress - enabling robust protection without violating LIN receiver input tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 26.5 V - ensures no conduction during normal LIN bus operation (dominant/recessive levels within 0–12 V range) |

| ESD Rating | ±30 kV contact/air (IEC 61000-4-2) - exceeds automotive OEM requirements for connector-level ESD immunity |
| AEC-Q101 Qualified | Yes (H3B HBM >8 kV) - validated for under-hood temperature cycling (-55 °C to +150 °C junction) |
| Package | SOD-323 - 2.85 mm × 1.60 mm footprint compatible with high-density PCB layouts and automated assembly |

Key Features
| Feature | Design Value |
|---|---|
| Single-line LIN-specific protection | Optimized for 12 V automotive LIN bus (ISO 11898-3), not generic USB or CAN applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STUSB4710QTR | Integrated USB-C port protection IC with integrated switch; higher capacitance (25 pF); requires external bias | Targeted at USB-C PD ports, not LIN; lacks AEC-Q101 qualification | Select only for USB-C applications requiring overvoltage + ESD + CC logic; not suitable for LIN bus replacement |
| ON Semiconductor NUP2114MUTAG | Bidirectional dual-line ESD array; 15 pF per line; ±30 kV IEC 61000-4-2; AEC-Q101 qualified | Protects two lines simultaneously; larger SOT-563 package; higher board area usage | Use when protecting multiple LIN signals or mixed-signal interfaces; not pin-compatible with VLIN2626-02G-E3-18 |
Compared with STUSB4710QTR and NUP2114MUTAG, the VLIN2626-02G-E3-18 offers superior LIN-specific optimization: lower capacitance (13.5–16 pF vs. ≥15 pF), smaller SOD-323 footprint, and dedicated 26.5 V VRWM matching LIN bus voltage envelopes - making it the preferred choice for single-line automotive LIN protection where space and signal fidelity are critical.

FAQ
What is the maximum operating temperature for VLIN2626-02G-E3-18?
The VLIN2626-02G-E3-18 has a junction temperature range of -55 °C to +150 °C and storage temperature range of -55 °C to +150 °C, fully supporting under-hood automotive environments. Its SOD-323 package and e3 tin plating ensure stable performance across this range without derating, and it is qualified per AEC-Q101 for thermal cycling and high-temperature life testing. The VLIN2626-02G-E3-18 maintains specified clamping and leakage parameters throughout this full range.
Is VLIN2626-02G-E3-18 pin-compatible with other SOD-323 ESD diodes?
The VLIN2626-02G-E3-18 uses standard SOD-323 pinout (anode at Pin 1, cathode at Pin 2) and matches industry-standard footprint dimensions (2.85 mm × 1.60 mm). However, electrical compatibility depends on VRWM, capacitance, and clamping behavior - for example, replacing a 12 V-rated diode with VLIN2626-02G-E3-18 may cause unintended conduction. Always verify system-level voltage margins before substitution. The VLIN2626-02G-E3-18 is not guaranteed drop-in compatible with non-LIN-optimized SOD-323 diodes.
Does VLIN2626-02G-E3-18 meet ISO 10605 ESD requirements?
Yes, the VLIN2626-02G-E3-18 is rated for ±30 kV contact and air discharge per ISO 10605 (C = 330 pF, R = 330 Ω), in addition to IEC 61000-4-2 compliance. This dual-standard validation confirms suitability for automotive ESD test protocols used by major OEMs. The device's clamping response and low leakage ensure robust protection without interfering with LIN bus communication integrity. The VLIN2626-02G-E3-18 was tested and certified to both standards per its official Vishay datasheet Rev. 1.6.
What is the clamping voltage of VLIN2626-02G-E3-18 at 4 A transient current?
The VLIN2626-02G-E3-18 exhibits a clamping voltage of 39–50 V at 4 A peak pulse current (8/20 μs waveform), per IEC 61000-4-5. This ensures downstream LIN transceivers - typically rated for absolute maximum input of 40–50 V - remain within safe operating limits during severe surge events. The clamping voltage is measured at the device terminals under standardized test conditions and remains stable across temperature. The VLIN2626-02G-E3-18 delivers predictable, repeatable clamping performance essential for automotive safety-critical buses.
Can VLIN2626-02G-E3-18 be used on CAN bus lines?
No - the VLIN2626-02G-E3-18 is optimized for LIN bus voltage levels (0–12 V) with 26.5 V VRWM and unidirectional architecture. CAN bus requires bidirectional protection with higher VRWM (typically ≥30 V) and stricter symmetry for differential signaling. Using VLIN2626-02G-E3-18 on CAN lines risks forward conduction during recessive state and inadequate clamping during dominant-state transients. For CAN, select Vishay's VCAN26xx or similar bidirectional AEC-Q101 devices. The VLIN2626-02G-E3-18 is strictly intended for LIN applications.
