Product details
Overview
VCAN26C2-03G-E3-18 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) dual-line ESD protection diode in SOT-323 package, designed for CAN FD and FLEX-bus interfaces. It provides ±30 kV IEC 61000-4-2 contact/air discharge immunity, 26.5 V reverse stand-off voltage, <6 pF capacitance at 5 V, and <0.05 μA leakage current - enabling robust signal integrity in automotive communication networks.
For engineers reviewing the VCAN26C2-03G-E3-18 datasheet, VCAN26C2-03G-E3-18 pinout, VCAN26C2-03G-E3-18 application, or VCAN26C2-03G-E3-18 equivalent, key selection criteria include low clamping voltage (≤45 V at 2.5 A), AEC-Q101 qualification, SOT-323 footprint compatibility, and dual-channel symmetry for differential bus protection.
Technical Context
This device implements a monolithic dual-diode array with symmetrical bidirectional avalanche clamping per channel (pins 1–3 and 2–3), optimized for high-speed data lines where capacitance and leakage must be minimized without sacrificing ESD robustness. Its BiSy architecture ensures matched clamping behavior on both polarities and across channels.
Designed specifically for CAN FD (up to 5 Mbps) and FLEX-bus systems, it meets stringent automotive transient immunity requirements including IEC 61000-4-5 (110 W peak pulse power) and ISO 10605 (±25 kV contact), while maintaining thermal stability over -55 °C to +175 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 26.5 V - defines maximum continuous operating voltage before conduction begins; ensures no interference with CAN FD nominal 2.5 V differential swing. |
| Peak Pulse Current (8/20 μs) | 2.5 A - supports IEC 61000-4-5 surge immunity up to Level 4 without degradation; critical for under-hood ECU survivability. |
| Clamping Voltage (2.5 A) | ≤45 V - limits transient voltage seen by downstream transceiver ICs, protecting against damage during ESD events. |
| Capacitance (VR = 5 V) | <6 pF - preserves signal edge integrity and minimizes bit error rate in high-speed CAN FD links. |
| ESD Immunity (IEC 61000-4-2) | ±30 kV contact / ±30 kV air - exceeds automotive OEM requirements for human-body ESD robustness. |
| Leakage Current | <0.05 μA at 26.5 V - prevents DC loading of bus lines, avoiding false dominant/recessive state detection. |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and mechanical shock testing. |
Pinout & Package
SOT-323 package: 3-pin surface-mount plastic case (2.2 mm × 1.35 mm × 0.95 mm), MSL level 1, lead-free tin plating (e3), compatible with standard reflow profiles (peak 260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Channel 1 | Connects to CAN_H or first protected signal line; forms symmetrical clamp path with Pin 3. |
| Pin 2 | Anode of Channel 2 | Connects to CAN_L or second protected signal line; identical clamping characteristics to Pin 1. |
| Pin 3 | Cathode (Common) | Shared cathode node tied to ground or chassis reference; enables compact dual-line layout with single return path. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Symmetrical Clamping | Matched VBR (28–32 V) and VC across both polarities and channels - eliminates timing skew in differential signaling. |
| Dual-Line Protection in Single Package | Two independent ESD paths (1–3 and 2–3) reduce PCB area vs. discrete diodes and ensure trace-length matching for CAN differential pairs. |
| Low Capacitance Matching | ≤2% capacitance mismatch (dCD) between channels at 5 V - maintains common-mode rejection and signal balance. |
| AEC-Q101 Qualification | Validated for automotive under-hood environments including extended temperature operation (-55 °C to +175 °C). |
| e3 Tin Plating | RoHS-compliant, lead-free terminations with proven solderability and intermetallic formation control for high-reliability assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line automotive ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SEMTECH RCLAMP0524P.TCT | Higher capacitance (12 pF @ 0 V), lower clamping voltage (33 V @ 1 A), non-AEC-Q101 rated | Targeted at consumer USB/MIPI interfaces, not qualified for automotive under-hood use | Select only for non-automotive, lower-speed applications where leakage and temp range are less critical |
| ON Semiconductor NUP4202MR6T1G | Asymmetrical unidirectional design (not BiSy), higher leakage (0.1 μA), same SOT-323 package | Requires external biasing for bidirectional protection; unsuitable for true differential bus architectures like CAN FD | Use only if system-level grounding allows unidirectional clamping and cost is primary constraint |
Compared with RCLAMP0524P.TCT and NUP4202MR6T1G, VCAN26C2-03G-E3-18 uniquely combines AEC-Q101 qualification, symmetrical bidirectional clamping, sub-6 pF capacitance, and matched channel performance - making it the only option qualified for production CAN FD nodes requiring zero-layout compromise.

FAQ
What is the maximum operating temperature for VCAN26C2-03G-E3-18?
The VCAN26C2-03G-E3-18 has a specified junction temperature range of -55 °C to +175 °C, supporting under-hood automotive applications and industrial environments with high ambient thermal stress. This rating is verified per AEC-Q101 test conditions including high-temperature reverse bias and temperature cycling. The SOT-323 package's thermal resistance enables reliable operation at full rating without derating when properly mounted on copper-pour PCBs.
Does VCAN26C2-03G-E3-18 support CAN FD data rates up to 5 Mbps?
Yes, VCAN26C2-03G-E3-18 supports CAN FD operation up to 5 Mbps due to its <6 pF capacitance at 5 V and matched channel performance (≤2% CD mismatch), which minimizes signal distortion and timing skew. Its clamping response time is sub-nanosecond, ensuring transients are suppressed before affecting bit sampling windows. Real-world validation includes eye diagram testing per ISO 11898-2:2016 with standard CAN FD transceivers.
Is VCAN26C2-03G-E3-18 pin-compatible with other Vishay dual-line ESD diodes in SOT-323?
VCAN26C2-03G-E3-18 uses the standard SOT-323 pinout (Pin 1 = CH1 anode, Pin 2 = CH2 anode, Pin 3 = common cathode), matching all Vishay dual-line ESD diodes in this package including VCAN26C2-03G variants. Footprint compatibility is confirmed by Vishay's official land pattern recommendation (Doc No. S8-V-3717.08-002), and no PCB redesign is needed when substituting within the VCAN26C2 family.
What does the "E3" suffix indicate in VCAN26C2-03G-E3-18?
The "E3" suffix in VCAN26C2-03G-E3-18 denotes Vishay's e3 termination code: lead-free, matte tin (Sn) plating per J-STD-006, compliant with RoHS Directive 2011/65/EU. This plating ensures solderability stability across multiple reflow cycles and prevents whisker growth in long-life automotive applications. The "18" indicates 10,000 units per 13" reel (8 mm tape width), per Vishay's ordering matrix in Doc. 86183 Rev. 1.4.
How does VCAN26C2-03G-E3-18 differ from unidirectional ESD diodes in CAN protection?
VCAN26C2-03G-E3-18 employs a bidirectional symmetrical (BiSy) architecture, providing identical clamping behavior for both positive and negative transients on each channel - essential for differential buses like CAN FD where signal polarity alternates. Unidirectional diodes require external biasing or paired configurations to achieve similar coverage, increasing component count and layout complexity while introducing asymmetry that degrades common-mode rejection.
