Product details
Overview
VCAN26A2-03SHE3A08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) dual-line ESD protection diode in SOT-23 package, designed for CAN and FLEX-Bus interfaces. It provides ±26.5 V reverse stand-off voltage, <0.05 μA leakage current, <13 pF load capacitance, ±30 kV IEC 61000-4-2 ESD immunity, and AEC-Q101 qualification for automotive applications.
For engineers reviewing the VCAN26A2-03SHE3A08 datasheet, VCAN26A2-03SHE3A08 pinout, VCAN26A2-03SHE3A08 application, or VCAN26A2-03SHE3A08 equivalent, key selection criteria include low clamping voltage (39–50 V at 3 A), matched diode capacitance (<1.5 pF mismatch), and robust 150 W peak pulse power handling per line under IEC 61000-4-5 conditions.
Technical Context
The VCAN26A2-03SHE3A08 integrates two identical, monolithically matched ESD protection paths (Pin 1–3 and Pin 2–3) in a single SOT-23 device, enabling symmetrical transient suppression on differential CAN bus lines. Its BiSy architecture ensures identical clamping behavior regardless of polarity, critical for maintaining signal integrity in high-speed serial buses.
It operates across –55 °C to +150 °C junction temperature range and meets AEC-Q101 stress test requirements including HTGB, HTRB, and TCT. The e3 tin-plated terminations and MSL Level 1 rating support lead-free reflow compatibility without moisture sensitivity concerns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse stand-off voltage | 26.5 V - maximum continuous working voltage before conduction begins; ensures no interference with CAN bus nominal ±12 V signaling. |
| Clamping voltage (3 A, 8/20 μs) | 39–50 V - limits transient voltage seen by downstream transceiver during surge events, protecting against damage. |
| Capacitance (0 V, 1 MHz) | 10–13 pF - minimizes signal distortion and timing skew on high-speed CAN FD (up to 5 Mbps) and FLEX-Bus links. |
| ESD immunity | ±30 kV contact / ±30 kV air - exceeds IEC 61000-4-2 Level 4, suitable for harsh automotive and industrial environments. |
| Peak pulse power | 150 W - sustains short-duration surges per line per IEC 61000-4-5 (8/20 μs), supporting system-level EMC compliance. |
| Leakage current | <0.05 μA at 26.5 V - prevents excessive DC loading on bus termination resistors and maintains bus bias stability. |
| Capacitance matching | <1.5 pF difference between channels - preserves differential signal balance and common-mode rejection in CAN transceivers. |
Pinout & Package
SOT-23 package (Type Code 6A2), 3-pin surface-mount, 9.2 mg weight, UL 94 V-0 molding compound, MSL Level 1, peak reflow temperature 260 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Channel 1 | Connects to CAN_H or first protected signal line; forms one half of bidirectional ESD path to common cathode. |
| Pin 2 | Anode of Channel 2 | Connects to CAN_L or second protected signal line; symmetrically matched to Pin 1 for differential bus protection. |
| Pin 3 | Common Cathode | Shared ground reference for both protection paths; must be connected to system ground with low-inductance trace. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional symmetrical (BiSy) structure | Identical forward/reverse clamping behavior on both channels ensures balanced protection for differential CAN signals without polarity dependency. |
| AEC-Q101 qualification | Validated for automotive underhood and infotainment systems, covering HTGB, HTRB, and temperature cycling stress tests. |
| Low capacitance matching | ≤1.5 pF inter-channel capacitance mismatch preserves signal integrity and reduces jitter in high-speed CAN FD implementations. |
| e3 tin plating | RoHS-compliant, lead-free terminations compatible with standard SnAgCu reflow profiles and eliminating Pb-related reliability concerns. |
| IEC 61000-4-5 surge capability | 150 W peak pulse power per channel supports system-level surge immunity up to 1 kV (line-to-ground) in automotive EMC testing. |

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 | Lower clamping voltage (33 V @ 1 A), higher capacitance (15 pF), non-AEC-Q101 rated | Targeted at consumer-grade CAN interfaces; not validated for automotive temperature cycling or humidity testing | Select when cost-sensitive industrial designs prioritize lower clamping over automotive qualification. |
| ON SEMICONDUCTOR NUP4202MR6T1G | Higher leakage (1 μA), asymmetric structure, 12 pF capacitance, AEC-Q101 qualified | Designed for general-purpose ESD protection; lacks BiSy symmetry and capacitance matching spec | Choose for legacy automotive systems where matched capacitance is not required and higher leakage is acceptable. |
Compared with RCLAMP0524P.TCT and NUP4202MR6T1G, the VCAN26A2-03SHE3A08 uniquely combines AEC-Q101 qualification, BiSy symmetry, sub-1.5 pF capacitance matching, and ≤0.05 μA leakage-making it optimal for next-generation CAN FD and FLEX-Bus nodes requiring precise differential signal integrity.

FAQ
What is the primary circuit role of the VCAN26A2-03SHE3A08 in a CAN bus system?
The VCAN26A2-03SHE3A08 serves as a bidirectional symmetrical ESD protection diode placed between CAN_H and CAN_L lines and system ground. It clamps transient voltages-such as ESD strikes or inductive switching spikes-to safe levels before they reach the CAN transceiver, preserving signal integrity and preventing damage. Its matched capacitance and low leakage ensure minimal impact on bus timing and bias networks in the VCAN26A2-03SHE3A08 implementation.
Does the VCAN26A2-03SHE3A08 support CAN FD data rates up to 5 Mbps?
Yes, the VCAN26A2-03SHE3A08 supports CAN FD operation up to 5 Mbps due to its low and tightly matched capacitance (10–13 pF, ≤1.5 pF mismatch) and minimal signal distortion. The device's <13 pF loading avoids excessive rise/fall time degradation, and its symmetrical clamping ensures consistent waveform fidelity on both CAN_H and CAN_L lines-key requirements verified in actual CAN FD compliance testing using the VCAN26A2-03SHE3A08.
Is the VCAN26A2-03SHE3A08 pin-compatible with other Vishay dual-line ESD protectors like VCAN26A2-03JH?
No, the VCAN26A2-03SHE3A08 is not pin-compatible with VCAN26A2-03JH. While both use SOT-23 packages, VCAN26A2-03JH employs a different pinout (Pin 1 = cathode, Pins 2/3 = anodes) and is unidirectional. The VCAN26A2-03SHE3A08 uses a common-cathode configuration (Pin 3 = cathode, Pins 1/2 = anodes) and is bidirectional. Substituting them requires PCB layout revision and validation of clamping behavior in the VCAN26A2-03SHE3A08 design.
What does "BiSy" mean for the VCAN26A2-03SHE3A08, and why is it important?
"BiSy" stands for Bidirectional Symmetrical-the VCAN26A2-03SHE3A08 exhibits identical clamping voltage and dynamic impedance characteristics in both positive and negative transient directions across each protection path. This symmetry is essential for differential buses like CAN and FLEX-Bus, where polarity reversal occurs naturally during signaling; asymmetry would cause unequal voltage limiting and introduce common-mode noise. The VCAN26A2-03SHE3A08 achieves this via matched monolithic diode structures, confirmed in its datasheet's clamping curves.
Can the VCAN26A2-03SHE3A08 be used in non-automotive applications such as industrial Ethernet or USB interfaces?
The VCAN26A2-03SHE3A08 is optimized for CAN and FLEX-Bus, not Ethernet or USB. Its ±26.5 V stand-off voltage exceeds typical USB (5 V) or Ethernet PHY (2.5–3.3 V) operating ranges, risking premature conduction and signal corruption. Additionally, its 10–13 pF capacitance may exceed USB 2.0's 5 pF limit. For those interfaces, dedicated low-capacitance protectors (e.g., USB-optimized TVS arrays) are recommended-VCAN26A2-03SHE3A08 should only be applied where its voltage and capacitance specs align with the target bus.
