Product details
Overview
VLIN26A1-03G-E3-08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) single-line ESD protection diode in SOT-323 package, designed for LIN-bus signal line protection. It features ±26.5 V working voltage range, <0.05 μA reverse leakage, <15 pF capacitance, ±30 kV IEC 61000-4-2 ESD immunity, and AEC-Q101 qualification for automotive environments.
For engineers reviewing the VLIN26A1-03G-E3-08 datasheet, VLIN26A1-03G-E3-08 pinout, VLIN26A1-03G-E3-08 application, or VLIN26A1-03G-E3-08 equivalent, key selection criteria include LIN-bus voltage tolerance, low clamping voltage under 3 A surge, sub-15 pF load capacitance, AEC-Q101 H3B ESD rating, and SOT-323 footprint compatibility with space-constrained automotive ECUs.
Technical Context
This device implements a symmetrical Zener-based clamping structure optimized for bidirectional transient suppression on unidirectional LIN bus lines. Its 28–32 V breakdown voltage and 32–50 V clamping range at 1–3 A pulses ensure robust protection without interfering with LIN's 12 V nominal signaling.
The SOT-323 package enables direct integration into LIN transceiver signal paths with minimal parasitic capacitance. Its MSL Level 1 rating and 175 °C maximum junction temperature support reflow soldering and high-reliability under-hood operation.

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 working voltage (±6.1 V), higher capacitance (30 pF), same SOT-323 package | Designed for CAN/LIN mixed-signal nodes; not rated for ±26.5 V continuous operation | Select only if system operates below 12 V and requires higher ESD energy absorption |
| TPD2E001DRYR | Unidirectional configuration, 5.5 V standoff, 12 pF capacitance, 3-pin SOT-553 package | Requires external biasing for LIN; smaller footprint but incompatible pinout and polarity | Use only when redesigning layout to accommodate unidirectional architecture and lower voltage rails |
Compared with ESDALC6V1-1U2 and TPD2E001DRYR, VLIN26A1-03G-E3-08 uniquely supports LIN's full ±26.5 V operating envelope with symmetrical clamping and automotive-grade thermal resilience-making it the only drop-in solution for legacy and next-gen LIN nodes requiring no signal conditioning or layout revision.

FAQ
What is the maximum clamping voltage of VLIN26A1-03G-E3-08 during an ESD event?
The VLIN26A1-03G-E3-08 clamps to 32 V at 1 A (8/20 μs pulse) and up to 50 V at its peak pulse current of 3 A. This ensures downstream LIN transceivers remain within safe operating voltage limits during standardized IEC 61000-4-2 discharge events. The clamping behavior is symmetrical and verified across both polarity directions.
Is VLIN26A1-03G-E3-08 compatible with standard LIN physical layer specifications?
Yes, VLIN26A1-03G-E3-08 meets ISO 11898-4 requirements for LIN bus protection: its ±26.5 V working range accommodates LIN's 12 V nominal plus transients, sub-15 pF capacitance preserves signal timing, and bidirectional symmetry aligns with LIN's single-wire open-drain topology. It is deployed in production LIN nodes by Tier 1 suppliers.
Does VLIN26A1-03G-E3-08 require external biasing or direction-specific placement?
No, VLIN26A1-03G-E3-08 is a fully symmetrical bidirectional device. Pins 1 and 3 are functionally identical, and pin 2 serves as the common reference. It requires no external biasing, polarity orientation, or supporting components-enabling direct in-line placement on any LIN data trace.
What is the moisture sensitivity level and reflow profile for VLIN26A1-03G-E3-08?
VLIN26A1-03G-E3-08 has MSL Level 1 per J-STD-020, meaning it is not moisture-sensitive and may be stored indefinitely at ambient conditions without dry pack requirements. Its peak reflow temperature is rated at 260 °C, compatible with standard lead-free soldering profiles used in automotive PCB assembly.
How does VLIN26A1-03G-E3-08 differ from generic TVS diodes in LIN applications?
Unlike generic TVS diodes, VLIN26A1-03G-E3-08 is optimized for LIN: it combines precise ±26.5 V standoff, ultra-low 10–15 pF capacitance, AEC-Q101 H3B qualification, and symmetrical clamping-all in SOT-323. Generic TVS parts often exceed 30 pF or lack automotive qualification, risking signal distortion or non-compliance in certified modules.
