Product details
Overview
VCAN26B2-03G-E3-08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) dual-line ESD protection diode in SOT-323 package, designed for CAN FD bus interfaces. It provides ±26.5 V reverse stand-off voltage, 3 pF typical capacitance at 5 V, <0.05 μA leakage current, ±25 kV IEC 61000-4-2 contact ESD immunity, and AEC-Q101 qualification for automotive electronics.
For engineers reviewing the VCAN26B2-03G-E3-08 datasheet, VCAN26B2-03G-E3-08 pinout, VCAN26B2-03G-E3-08 application, or VCAN26B2-03G-E3-08 equivalent, key selection criteria include low-capacitance dual-line protection, CAN FD data-rate compatibility, AEC-Q101 qualification, and SOT-323 footprint constraints in space-constrained automotive control units.
Technical Context
The VCAN26B2-03G-E3-08 integrates two matched, bidirectional ESD protection paths (pin 1–3 and pin 2–3) with symmetrical clamping behavior. Its BiSy architecture ensures identical forward and reverse breakdown characteristics, enabling robust transient suppression on differential CAN bus lines without polarity sensitivity.
It operates across –55 °C to +150 °C junction temperature, supports peak pulse currents up to 2 A (8/20 μs), and delivers clamping voltages of ≤41 V at 1 A and ≤50 V at 2 A per line - critical for preserving signal integrity during ESD events in high-speed automotive networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protection Type | Bidirectional symmetrical (BiSy) dual-line ESD clamp - protects both CAN_H and CAN_L lines with matched response. |
| Reverse Stand-off Voltage | 26.5 V - defines maximum continuous working voltage before conduction; aligns with 24 V automotive supply rails. |
| Capacitance (VR = 5 V) | 3 pF (typ.) - minimizes signal distortion and timing skew on CAN FD buses operating up to 5 Mbps. |
| Leakage Current | <0.05 μA at 26.5 V - ensures negligible DC loading on bus terminations and transceivers. |
| ESD Immunity | ±25 kV contact / ±30 kV air (IEC 61000-4-2) - exceeds automotive OEM requirements for system-level ESD robustness. |
| Clamping Voltage (1 A) | ≤41 V (typ.) - limits transient overvoltage seen by downstream CAN transceiver I/O pins during ESD events. |
| AEC-Q101 Qualified | Yes - validated for automotive underhood and cabin applications per stress test conditions including HBM & TLP. |
Pinout & Package
SOT-323 package: 3-pin surface-mount plastic case (MSL level 1, peak reflow ≤260 °C), dimensions 2.2 × 1.35 × 0.95 mm, tin-plated e3 terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode/Cathode of Line 1 ESD path | Connects to CAN_H; forms first bidirectional protection path with Pin 3 (common cathode/anode). |
| Pin 2 | Anode/Cathode of Line 2 ESD path | Connects to CAN_L; forms second independent bidirectional protection path with Pin 3. |
| Pin 3 | Common terminal (cathode/anode) | Shared reference node for both protection channels; connects to ground or common bus return plane. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line BiSy architecture | Enables matched, polarity-insensitive protection for differential CAN FD signals without external biasing. |
| 3 pF capacitance at 5 V | Maintains signal rise/fall time integrity on high-speed CAN FD links (up to 5 Mbps) with minimal jitter impact. |
| ±25 kV IEC 61000-4-2 contact ESD | Meets or exceeds ISO 11898-2 and OEM ESD test plans for controller area network physical layer robustness. |
| AEC-Q101 qualification | Validates reliability for automotive powertrain, body control, and ADAS modules requiring extended temperature operation. |
| e3 tin plating | Ensures RoHS-compliant, lead-free solderability and intermetallic stability in automated SMT reflow processes. |

Use Scenario: ESD hardening of CAN-based camera synchronization and configuration links in surround-view or driver-monitoring systems. IC Role / Device Role / Timing Role: Secondary-level protection on short PCB traces between image sensor SoC and CAN transceiver IC. Use Value: Provides 40–50 V clamping at 2 A peak pulse to prevent transient-induced bit errors during camera boot or firmware updates. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line CAN bus ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VCAN26C2-03G-E3-08 | Higher clamping voltage (≤45 V at 1 A); same 26.5 V VRWM and 3 pF capacitance; updated process with improved TLP consistency. | Identical pinout and footprint; intended as direct replacement per Vishay's "Not For New Designs" notice for VCAN26B2-03G. | Select for new designs requiring latest-generation ESD performance and full lifecycle support; compatible with existing VCAN26B2-03G layouts. |
| TPD2E001DRYR | Lower VRWM (5.5 V); 12 pF capacitance; single-channel (requires two devices); no AEC-Q101 qualification. | Targeted at low-voltage consumer or industrial CAN-like interfaces (e.g., RS-485 derivatives), not automotive-grade CAN FD. | Use only in non-automotive, cost-sensitive applications where 26.5 V standoff and AEC-Q101 are not required. |
Compared with VCAN26B2-03G-E3-08, VCAN26C2-03G-E3-08 offers enhanced long-term reliability and updated ESD consistency while maintaining full mechanical and electrical compatibility; TPD2E001DRYR serves non-automotive use cases but lacks the voltage rating, low capacitance, and qualification needed for CAN FD deployment.

FAQ
Is VCAN26B2-03G-E3-08 qualified for automotive applications?
Yes, VCAN26B2-03G-E3-08 is AEC-Q101 qualified and rated for operation from –55 °C to +150 °C junction temperature. It meets human body model (HBM) Class H3B (>8 kV) and IEC 61000-4-2 ESD requirements, making it suitable for under-hood and cabin automotive modules including ECUs and gateways where VCAN26B2-03G-E3-08 is deployed.
What is the recommended PCB layout for VCAN26B2-03G-E3-08?
Place VCAN26B2-03G-E3-08 as close as possible to the CAN connector with short, symmetric traces to Pins 1 and 2, and a low-inductance connection from Pin 3 to chassis or system ground. Avoid vias in protection paths and maintain ≥0.2 mm clearance to adjacent copper. The SOT-323 footprint matches standard IPC-7351B recommendations per Vishay document 21113.
Does VCAN26B2-03G-E3-08 support CAN FD data rates up to 5 Mbps?
Yes, VCAN26B2-03G-E3-08 supports CAN FD operation up to 5 Mbps due to its 3 pF typical capacitance at 5 V and matched diode capacitance (dCD ≤0.3 pF), which minimizes signal distortion and maintains differential impedance integrity on high-speed CAN bus traces where VCAN26B2-03G-E3-08 is applied.
What is the meaning of "Not For New Designs" for VCAN26B2-03G-E3-08?
"Not For New Designs" indicates Vishay has superseded VCAN26B2-03G-E3-08 with VCAN26C2-03G-E3-08 for future projects. Existing designs may continue using VCAN26B2-03G-E3-08, but new designs should adopt the newer variant, which offers improved TLP consistency and extended product lifecycle support while maintaining full pin and functional compatibility with VCAN26B2-03G-E3-08.
How does the clamping voltage of VCAN26B2-03G-E3-08 compare to competing ESD diodes?
VCAN26B2-03G-E3-08 clamps to ≤41 V at 1 A and ≤50 V at 2 A (8/20 μs), which is lower than many general-purpose TVS diodes (often >60 V at 1 A). This tighter clamping protects CAN transceivers with 40 V absolute maximum ratings, and its matched dual-path design ensures balanced suppression - a key differentiator versus discrete single-diode solutions used with VCAN26B2-03G-E3-08.
