Product details
Overview
VLIN3333-02GHE3-08 from Vishay Semiconductors is a single-line, low-capacitance ESD-protection diode optimized for LIN-Bus signal lines, featuring ±33 V working voltage, <13 pF load capacitance, <0.05 μA leakage current, and ±30 kV IEC 61000-4-2 ESD immunity. It is AEC-Q101 qualified and housed in the compact SOD-323 package for automotive body electronics.
For engineers reviewing the VLIN3333-02GHE3-08 datasheet, VLIN3333-02GHE3-08 pinout, VLIN3333-02GHE3-08 application, or VLIN3333-02GHE3-08 equivalent, key selection criteria include LIN-Bus clamping performance (VC ≤ 57 V at 3.5 A), ultra-low capacitance for signal integrity, AEC-Q101 qualification, and SOD-323 footprint compatibility with space-constrained automotive PCBs.
Technical Context
This device functions as a unidirectional transient voltage suppressor (TVS) diode configured for LIN-Bus line protection, operating between ground and the protected signal line. Its clamping behavior is defined by a reverse breakdown voltage of 36–40 V and a peak clamping voltage of 50–57 V under 3.5 A 8/20 μs surge conditions.
The SOD-323 package supports reflow soldering per J-STD-020 MSL level 1, with tin-plated e3 terminations and UL 94 V-0 molding compound. It delivers robust ESD resilience (±30 kV contact/air) and H3B-class HBM (>8 kV) per AEC-Q101, targeting automotive subsystems requiring high-reliability interface protection.

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); bidirectional; higher CD (15 pF) | Designed for 5 V logic buses (e.g., CAN FD, USB), not LIN's 12 V supply domain | Select only if protecting sub-6 V interfaces; unsuitable for direct LIN-Bus replacement due to voltage mismatch |
| TPD2E001DRYR | Two-channel; lower clamping (VC = 12 V @ 1 A); CD = 11 pF; non-AEC-Q101 | Targeted at consumer port protection (USB, HDMI), lacks automotive qualification and LIN-specific stand-off | Acceptable for non-automotive LIN prototypes; not recommended for production automotive systems requiring AEC-Q101 compliance |
Compared with ESDALC6V1-1U2 and TPD2E001DRYR, VLIN3333-02GHE3-08 uniquely combines 33 V stand-off, AEC-Q101 qualification, and <13 pF capacitance-making it the only option among the three validated for production-grade LIN-Bus protection in automotive modules.

FAQ
What is the primary function of VLIN3333-02GHE3-08 in a LIN-Bus system?
VLIN3333-02GHE3-08 serves as a unidirectional ESD protection diode placed on the LIN data line to clamp transient overvoltages-such as those from electrostatic discharge or load dump-to safe levels. Its 33 V stand-off voltage aligns with LIN's nominal 12 V supply and 27 V max bus voltage, ensuring normal signal operation while suppressing ±30 kV ESD events per IEC 61000-4-2. The VLIN3333-02GHE3-08 maintains signal fidelity via <13 pF capacitance and supports automotive reliability with AEC-Q101 qualification.
Is VLIN3333-02GHE3-08 compatible with standard SOD-323 footprints?
Yes, VLIN3333-02GHE3-08 uses the industry-standard SOD-323 package with precise dimensions (2.50 mm × 1.25 mm × 0.95 mm) and cathode bar marking on terminal 1. Vishay provides a recommended footprint in the datasheet (Document No. 86169, page 4), including pad lengths of 1.15 mm and spacing of 1.60 mm. The VLIN3333-02GHE3-08 is compatible with J-STD-020-compliant reflow profiles and requires no layout modification when replacing other SOD-323 ESD diodes with identical pinout and polarity.
Does VLIN3333-02GHE3-08 meet automotive qualification standards?
Yes, VLIN3333-02GHE3-08 is fully AEC-Q101 qualified for stress testing including HBM (>8 kV, Class H3B), temperature cycling, and high-temperature operating life. It operates across −55 °C to +150 °C junction temperature and is rated MSL level 1 for moisture sensitivity. The VLIN3333-02GHE3-08 also complies with RoHS and features e3 tin-plated terminations, making it suitable for automotive production use in body electronics and comfort systems.
How does VLIN3333-02GHE3-08 compare to generic ESD diodes in LIN applications?
Unlike generic ESD diodes, VLIN3333-02GHE3-08 is specifically characterized for LIN-Bus: its 33 V VRWM avoids false triggering during normal bus operation (which peaks near 18 V), and its clamping curve ensures VC stays below 57 V at 3.5 A-within safe margins for LIN transceivers. Generic diodes often have mismatched stand-off voltages or higher capacitance (>20 pF), risking communication errors. The VLIN3333-02GHE3-08 is the only part in its class with documented LIN-Bus optimization and AEC-Q101 validation.
What is the maximum peak pulse current rating for VLIN3333-02GHE3-08?
The VLIN3333-02GHE3-08 is rated for a peak pulse current (IPPM) of 3.5 A under IEC 61000-4-5 8/20 μs waveform conditions at 25 °C. This corresponds to a peak pulse power (PPP) of 200 W. The device maintains clamping voltage ≤57 V at this current, ensuring downstream LIN transceivers remain within absolute maximum ratings. Derating is not required up to +125 °C ambient, as confirmed in Vishay's thermal characterization data for VLIN3333-02GHE3-08.
