Product details
Overview
VCAN26C2-03G-E3-08 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, and ±30 kV IEC 61000-4-2 contact/air discharge immunity - designed for CAN FD and FLEX-bus interface line protection.
For engineers reviewing the VCAN26C2-03G-E3-08 datasheet, VCAN26C2-03G-E3-08 pinout, VCAN26C2-03G-E3-08 application, or VCAN26C2-03G-E3-08 equivalent, key selection criteria include clamping voltage under 2.5 A surge (≤45 V), matched diode capacitance (<2% mismatch), AEC-Q101 qualification, tin-plated e3 terminations, and SOT-323 footprint compatibility with high-speed automotive data buses.
Technical Context
This device implements two independent, symmetrical Zener-based ESD protection paths (pin 1–3 and pin 2–3) optimized for bidirectional signal integrity on differential or parallel bus lines. Its low 5–6 pF capacitance at 5 V reverse bias ensures minimal signal distortion up to 100 MHz, while the 28–32 V breakdown range supports robust overvoltage clamping without false triggering during normal CAN FD operation (±2 V common-mode, ±40 V fault).
The SOT-323 package enables compact placement adjacent to connectors or transceivers, with MSL Level 1 moisture sensitivity and 260 °C peak reflow tolerance. It meets AEC-Q101 stress requirements including HBM >8 kV and full IEC 61000-4-2/ISO 10605 ESD compliance - confirming suitability for automotive infotainment, body control, and ADAS domain controller interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 26.5 V - maximum continuous working voltage before conduction; ensures no interference with CAN FD nominal ±2.5 V differential swing. |
| Clamping Voltage (1 A) | 34–37 V - limits transient voltage seen by downstream CAN transceiver during 8/20 μs surge, preserving signal integrity. |
| Clamping Voltage (2.5 A) | 40–45 V - defines worst-case rail clamp level under full IEC 61000-4-5 surge, protecting against short-circuit faults. |
| Capacitance (VR = 5 V) | 5–6 pF - maintains <0.1 UI timing jitter on 5 Mbps CAN FD links; critical for maintaining bit error rate below 10⁻¹². |
| Leakage Current | <0.05 μA at 26.5 V - prevents DC loading of bus termination resistors and avoids false wake-up in low-power sleep modes. |
| ESD Rating | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - exceeds automotive OEM requirements for connector-level ESD robustness. |
| Breakdown Voltage | 28–32 V at 1 mA - tight distribution ensures consistent turn-on across production lots and temperature (-55 to +175 °C). |
Pinout & Package
SOT-323 package: 3-pin surface-mount, 1.3 mm × 1.8 mm × 0.9 mm body, gull-wing leads, MSL Level 1, 260 °C max reflow peak temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Line 1 Protection Path | Connects to first protected signal line (e.g., CAN_H); forms symmetrical clamp to common cathode (Pin 3). |
| Pin 2 | Anode of Line 2 Protection Path | Connects to second protected signal line (e.g., CAN_L); identical electrical behavior to Pin 1 for matched protection. |
| Pin 3 | Common Cathode | Shared return node for both protection paths; must be connected to system ground plane with low-inductance path. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Symmetrical (BiSy) Clamping | Enables identical positive/negative transient suppression on both signal lines without polarity constraints - essential for differential bus protocols like CAN FD. |
| Dual-Line Integration | Single SOT-323 package protects two independent signal lines, reducing PCB area by 40% vs. discrete diodes and eliminating inter-channel skew. |
| Low Capacitance Matching | ≤2% capacitance mismatch (CD13 vs. CD23 at VR = 5 V) preserves differential signal balance and minimizes common-mode noise conversion. |
| AEC-Q101 Qualification | Validated for automotive underhood and cabin environments, including temperature cycling (-55 to +175 °C), mechanical shock, and HBM >8 kV. |
| e3 Tin Plating | RoHS-compliant Sn termination ensures reliable solderability, eliminates lead-free assembly concerns, and supports Pb-free reflow profiles. |

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 |
|---|---|---|---|
| SEMTECH RCLAMP0524P.TCT | Higher capacitance (12 pF @ 0 V), lower clamping (33 V @ 1 A), same SOT-323 package and ±24 V standoff. | Optimized for USB 2.0 and general-purpose I/O; less suitable for CAN FD due to higher capacitance-induced jitter. | Select when lower clamping voltage outweighs bandwidth needs - verify signal integrity at target data rate. |
| LITTELFUSE SP1003-04UTG | Asymmetrical configuration (unidirectional), 5.5 V standoff, 0.5 pF capacitance, SOT-23-6 package. | Designed for low-voltage logic (3.3 V/5 V), not automotive-grade; lacks AEC-Q101 and IEC 61000-4-2 ±30 kV rating. | Use only in non-automotive, low-voltage digital interfaces where ultra-low capacitance is mandatory and ESD severity is moderate. |
Compared with RCLAMP0524P.TCT and SP1003-04UTG, VCAN26C2-03G-E3-08 uniquely balances automotive-grade reliability (AEC-Q101, ±30 kV), CAN FD–optimized capacitance (<6 pF), and matched dual-line symmetry - making it the only option qualified for under-hood CAN FD node protection without derating or layout compromise.
