Product details
Overview
VCAN33A2-HT5-G3-08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) dual-line ESD protection diode in DFN1110-3A package, rated for ±33 V working voltage, <0.05 μA reverse leakage, <6 pF capacitance at 5 V, and ±20 kV IEC 61000-4-2 ESD immunity - designed specifically for CAN FD bus interface protection in automotive and industrial control systems.
For engineers reviewing the VCAN33A2-HT5-G3-08 datasheet, VCAN33A2-HT5-G3-08 pinout, VCAN33A2-HT5-G3-08 application, or VCAN33A2-HT5-G3-08 equivalent, key selection criteria include low clamping voltage (≤52 V at 1.6 A), matched line capacitance (<0.12 pF difference), AEC-Q101 qualification, and DFN1110-3A footprint compatibility with high-density CAN transceiver layouts.
Technical Context
The VCAN33A2-HT5-G3-08 implements a symmetrical dual-channel TVS structure with common cathode (pin 3) and independent anodes (pins 1 and 2), enabling simultaneous bidirectional protection of two CAN FD signal lines without polarity sensitivity. Its low 4.1–6 pF capacitance at 5 V reverse bias ensures minimal signal integrity degradation on high-speed differential buses up to 5 Mbps.
It meets AEC-Q101 stress requirements including HBM >8 kV and operates across –55 °C to +150 °C junction temperature, with MSL Level 1 soldering compatibility (peak 260 °C) and tin-plated e3 terminations for reliable reflow assembly in automotive production environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protection Type | Bidirectional symmetrical (BiSy) dual-line TVS for CAN FD differential pair |
| Working Voltage (VRWM) | ±33 V - matches nominal CAN FD bus common-mode range and withstands transients without conduction |
| Clamping Voltage (VC) | ≤52 V at 1.6 A peak pulse - limits transient overvoltage to safe levels for ISO 11898-2/3-compliant transceivers |
| Capacitance (CD) | 4.1–6 pF at VR = 5 V - preserves signal rise/fall times and minimizes jitter on 5 Mbps CAN FD links |
| ESD Rating | ±20 kV contact/air (IEC 61000-4-2) - exceeds automotive OEM ESD immunity requirements |
| Leakage Current (IR) | <0.05 μA at 33 V - avoids DC loading or bias shift in high-impedance CAN receiver inputs |
| Package | DFN1110-3A (1.1 × 1.0 × 0.4 mm) - enables ultra-compact placement adjacent to CAN controller or transceiver |
Pinout & Package
DFN1110-3A is a 3-terminal, leadless surface-mount package with exposed thermal pad (not electrically connected), 0.65 mm pin pitch, and pin 1 marked by dot. Pin 3 serves as common cathode; pins 1 and 2 are independent anodes for Line 1 and Line 2 protection paths.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode for Channel 1 (Line A) | Connects to CAN_H or CAN_L of first protected line; conducts during negative transients |
| Pin 2 | Anode for Channel 2 (Line B) | Connects to complementary CAN line; enables independent, matched protection of differential pair |
| Pin 3 | Common Cathode | Connected to ground plane; provides low-inductance return path for both ESD current paths |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood and body electronics per stress test conditions including HBM >8 kV |
| Capacitance matching (dCD) | ≤0.12 pF difference between channels - maintains CAN FD differential signal symmetry and common-mode rejection |
| e3 termination (Sn plating) | Tin-plated side walls ensure robust solder wetting and intermetallic formation in lead-free reflow profiles |
| MSL Level 1 rating | Unlimited floor life at ≤30 °C/60 % RH - eliminates bake requirements before SMT assembly |
| Low clamping dispersion | Typical VC = 47 V at 1.6 A (IEC 61000-4-5) - tight distribution reduces design margin uncertainty |
Applications
| Automotive CAN FD Nodes | Industrial Fieldbus Gateways |
|---|---|
Use Scenario: Protection of CAN FD transceivers in ADAS domain controllers and battery management systems exposed to load dump and ESD events.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line CAN FD ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUF2221MUTAG | Higher capacitance (12 pF typical), lower clamping (42 V), no AEC-Q101 qualification | Suitable for consumer-grade CAN interfaces but not automotive underhood use | Select when cost priority outweighs AEC-Q101 compliance and board space allows larger capacitance impact |
| Infineon ESD224-B1-W | Single-line device (requires two units), 5.5 pF, AEC-Q101 qualified, same DFN1110-3A footprint | Requires duplicated layout and routing; adds 0.1 mm trace length mismatch risk | Choose only if existing design uses ESD224-B1-W and dual-device placement is already validated |
Compared with NUF2221MUTAG and ESD224-B1-W, the VCAN33A2-HT5-G3-08 uniquely delivers AEC-Q101 qualification, matched dual-channel capacitance, and single-package integration - reducing PCB area by 35 % and eliminating inter-channel skew in critical CAN FD timing paths.

FAQ
What is the maximum operating temperature range for the VCAN33A2-HT5-G3-08?
The VCAN33A2-HT5-G3-08 supports a junction temperature range of –55 °C to +150 °C, making it suitable for under-hood automotive applications and industrial environments with wide ambient swings. This rating is verified per AEC-Q101 stress testing and applies across its full electrical specification range without derating.
Does the VCAN33A2-HT5-G3-08 require external biasing or control signals?
No, the VCAN33A2-HT5-G3-08 is a passive TVS diode array with no external bias or enable requirements. It operates solely on voltage threshold conduction: each channel clamps when reverse voltage exceeds ~36 V (VBR min), automatically returning to high-impedance state once transient subsides - fully transparent to normal CAN FD signaling.
Is the VCAN33A2-HT5-G3-08 pin-compatible with earlier Vishay CAN protection devices like VCAN26A2?
No, the VCAN33A2-HT5-G3-08 is not pin-compatible with VCAN26A2. While both use DFN1110-3A packages, VCAN26A2 has different pin assignment (common anode configuration) and voltage rating (±26 V). Substitution requires schematic and layout revision to accommodate reversed polarity and updated clamping thresholds.
How does the capacitance matching specification (dCD ≤ 0.12 pF) benefit CAN FD performance?
The ≤0.12 pF capacitance mismatch between channels in the VCAN33A2-HT5-G3-08 minimizes differential signal distortion and common-mode conversion on CAN FD buses. This tight matching preserves eye diagram integrity at 5 Mbps, reduces bit error rate in noisy environments, and supports robust operation with ISO 11898-2-compliant transceivers without additional equalization.
Can the VCAN33A2-HT5-G3-08 be used for LIN bus protection?
The VCAN33A2-HT5-G3-08 is not recommended for LIN bus protection due to its ±33 V standoff voltage, which exceeds LIN's 18 V max operating range and risks premature conduction during normal bus operation. For LIN, Vishay recommends dedicated low-voltage protectors such as VBUS05M2-HT5, which features 5.5 V VRWM and optimized clamping for 12 V automotive networks.
