Product details
Overview
VCAN26C2-03GHE3-18 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) dual-line ESD protection diode in SOT-323 package, rated for ±26.5 V reverse stand-off voltage, <6 pF capacitance at 5 V, <0.05 μA leakage, ±30 kV IEC 61000-4-2 contact/air discharge, and AEC-Q101 qualified for automotive CAN FD interfaces.
For engineers reviewing the VCAN26C2-03GHE3-18 datasheet, VCAN26C2-03GHE3-18 pinout, VCAN26C2-03GHE3-18 application, or VCAN26C2-03GHE3-18 equivalent, key selection criteria include low-capacitance dual-line protection, automotive-grade reliability, CAN FD signal integrity preservation, and SOT-323 footprint compatibility with high-density PCB layouts.
Technical Context
This device implements a symmetrical dual-channel TVS architecture with matched clamping characteristics across both protected lines (pin 1–3 and pin 2–3), enabling balanced transient suppression on differential CAN FD bus pairs without polarity sensitivity. Its BiSy design eliminates need for orientation-aware placement.
It delivers 110 W peak pulse power per line under IEC 61000-4-5 8/20 μs surge, with clamping voltage ≤45 V at 2.5 A, and maintains <2% capacitance mismatch between channels - critical for maintaining common-mode noise rejection and signal timing integrity in high-speed automotive serial buses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 26.5 V - maximum continuous operating voltage before conduction; ensures no interference with 24 V automotive supply rails or CAN FD nominal 5 V signaling. |
| Peak Pulse Current (per line) | 2.5 A - withstands IEC 61000-4-5 surges without degradation; supports robust EMC compliance in harsh vehicle environments. |
| Clamping Voltage @ 2.5 A | ≤45 V - limits transient overvoltage to safe levels for downstream CAN transceivers (e.g., TJA1042, SN65HVD230). |
| Capacitance @ 5 V | ≤6 pF - preserves signal edge rate and minimizes bit error rate in CAN FD up to 5 Mbps. |
| ESD Immunity | ±30 kV contact / ±30 kV air - exceeds IEC 61000-4-2 Level 4, enabling reliable operation in assembly, service, and field handling. |
| AEC-Q101 Qualified | Yes - validated for automotive underhood and cabin applications with junction temperature range −55 °C to +175 °C. |
Pinout & Package
SOT-323 package: 3-pin surface-mount plastic case, 2.2 mm × 1.35 mm × 0.95 mm body, MSL level 1, tin-plated terminations (e3), compatible with standard reflow profiles (peak 260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Channel 1 | Connects to first CAN line (e.g., CAN_H); forms symmetrical protection path with Pin 3 as common cathode. |
| Pin 2 | Anode of Channel 2 | Connects to second CAN line (e.g., CAN_L); identical electrical behavior to Pin 1 for differential balance. |
| Pin 3 | Common Cathode | Shared low-impedance return path for both protection channels; must be connected to ground plane with minimal inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Symmetrical (BiSy) Architecture | Enables polarity-agnostic placement on differential buses - eliminates risk of misorientation during automated assembly. |
| Dual-Line Protection in Single Package | Reduces board space by 50% vs. discrete single-line protectors; simplifies layout and routing for CAN FD differential pairs. |
| Capacitance Matching (≤2% ΔCD) | Maintains differential signal symmetry and common-mode rejection ratio (CMRR) >60 dB at 1 MHz. |
| AEC-Q101 Qualification | Validated for automotive use including thermal cycling, humidity bias, and mechanical shock - supports 15-year vehicle lifecycle requirements. |
Applications

IC Role / Device Role / Timing Role: Matched dual-channel clamp minimizing skew between differential sensor outputs to preserve ratiometric measurement integrity. Use Value: Limits transient-induced offset error to <0.5% full-scale, supporting ASIL-B diagnostic coverage targets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STUSB4710QTR | Higher capacitance (12 pF @ 5 V), unidirectional, integrated USB Type-C CC line protection logic. | Designed for USB PD port protection, not CAN/FLEX-bus; lacks AEC-Q101 qualification and BiSy symmetry. | Select only for USB interface applications requiring integrated protocol-aware control - not suitable for automotive CAN FD. |
| ON Semiconductor NUP4202MR6T1G | Lower clamping voltage (VC ≤33 V @ 1 A), but higher capacitance (15 pF @ 0 V), non-AEC-Q101, SOT-563 package (larger footprint). | Targeted at general-purpose industrial I/O protection; insufficient for 5 Mbps CAN FD due to bandwidth limitation from higher CD. | Acceptable for legacy CAN 2.0 (125 kbps) or low-speed digital I/O where signal integrity is less critical. |
Compared with STUSB4710QTR and NUP4202MR6T1G, VCAN26C2-03GHE3-18 uniquely combines AEC-Q101 qualification, BiSy symmetry, sub-6 pF capacitance, and matched dual-channel performance - making it the only option among the three validated for automotive CAN FD and FLEX-bus high-speed differential protection.

FAQ
What is the primary circuit role of the VCAN26C2-03GHE3-18 in a CAN FD system?
The VCAN26C2-03GHE3-18 serves as a bidirectional symmetrical dual-line transient voltage suppressor, placed at the physical interface between the vehicle harness and CAN FD transceiver. It clamps ESD and surge events to safe levels while adding minimal capacitive loading - ensuring signal integrity up to 5 Mbps. Its matched channels preserve differential timing, and its ±26.5 V stand-off voltage accommodates automotive supply variations without false triggering.
Does the VCAN26C2-03GHE3-18 require external biasing or control signals?
No, the VCAN26C2-03GHE3-18 is a passive, diode-based ESD protection device with no external bias or control requirements. It operates solely based on its intrinsic avalanche and forward conduction characteristics. The device conducts only during overvoltage transients - drawing zero static current under normal operation (IR < 0.05 μA at 26.5 V), making it ideal for low-power automotive modules where quiescent current is tightly constrained.
How does the VCAN26C2-03GHE3-18 differ from single-line ESD protectors like the VCAN26C1-03GHE3-18?
The VCAN26C2-03GHE3-18 integrates two independent, matched protection paths (pins 1–3 and 2–3) in one SOT-323 package, whereas the VCAN26C1-03GHE3-18 protects only one line. This dual-channel design enables direct protection of differential CAN FD pairs without discrete pairing, reduces PCB area by ~40%, and guarantees ≤2% capacitance matching - a critical requirement for maintaining common-mode noise immunity that single-line devices cannot provide inherently.
Is the VCAN26C2-03GHE3-18 compatible with lead-free reflow soldering processes?
Yes, the VCAN26C2-03GHE3-18 features e3-compliant tin-plated terminations and is qualified for standard lead-free reflow profiles. Its SOT-323 package supports peak temperatures up to 260 °C (per J-STD-020), with MSL level 1 rating - meaning it can be stored indefinitely at ambient conditions without baking prior to assembly. The molding compound meets UL 94 V-0 flammability requirements.
What is the significance of the "HE3-18" suffix in VCAN26C2-03GHE3-18?
The "HE3-18" suffix denotes specific manufacturing and packaging attributes: "H" indicates AEC-Q101 qualification, "E3" confirms e3-compliant tin plating, and "18" specifies 10,000 units per 13-inch reel (8 mm tape). This full ordering code ensures traceability to automotive-grade production lots, RoHS compliance, and logistics readiness for high-volume automotive manufacturing lines.
