Product details
Overview
VCAN36A2-HT5-G3-08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) dual-line ESD protection diode in DFN1110-3A package, rated for ±36 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 line protection in automotive and industrial control networks.
For engineers reviewing the VCAN36A2-HT5-G3-08 datasheet, VCAN36A2-HT5-G3-08 pinout, VCAN36A2-HT5-G3-08 application, or VCAN36A2-HT5-G3-08 equivalent, key selection criteria include clamping voltage (≤58 V at 1.6 A), diode capacitance matching (≤0.12 pF), AEC-Q101 qualification, and DFN1110-3A footprint compatibility with high-density CAN transceiver layouts.
Technical Context
The VCAN36A2-HT5-G3-08 integrates two matched, low-capacitance ESD protection paths between pins 1–3 and 2–3, enabling symmetrical transient suppression on both CAN_H and CAN_L lines without polarity sensitivity. Its BiSy architecture ensures identical clamping behavior under positive and negative ESD events.
Designed for CAN FD systems operating up to 5 Mbps, it maintains signal integrity via sub-4.6 pF capacitance at 5 V reverse bias and achieves robust system-level protection with 92 W peak pulse power (8/20 μs) and 1.6 A peak pulse current per line.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | ±36 V - supports full CAN FD common-mode range and withstands load-dump transients in 24 V automotive systems. |
| Clamping Voltage | ≤58 V at 1.6 A (8/20 μs) - limits voltage stress on downstream CAN transceivers during surge events. |
| Capacitance | 3.8–4.6 pF at VR = 5 V - minimizes signal distortion and timing skew on high-speed CAN FD buses. |
| ESD Immunity | ±20 kV contact/air (IEC 61000-4-2) - meets automotive OEM ESD test requirements for infotainment and body control modules. |
| Leakage Current | <0.05 μA at 36 V - prevents excessive quiescent current in always-on CAN wake-up circuits. |
| Breakdown Voltage | 39–45 V at 1 mA - ensures reliable triggering above normal bus operating voltage while avoiding false conduction. |
| AEC-Q101 Qualified | Qualified per AEC-Q101 Rev. G - validated for automotive under-hood and chassis applications with TJ = −55 °C to +150 °C operation. |
Pinout & Package
Package: DFN1110-3A (1.1 mm × 1.0 mm × 0.4 mm), MSL Level 1, e3 tin-plated terminations, AOI-capable, 10 k/reel tape-and-reel packaging (code G3-08).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | CAN_H protection anode/cathode | Input terminal for first protected line; bidirectional path to Pin 3 enables symmetrical ESD clamping on CAN_H. |
| Pin 2 | CAN_L protection anode/cathode | Input terminal for second protected line; independent but matched bidirectional path to Pin 3 for CAN_L. |
| Pin 3 | Common cathode/anode reference | Shared low-inductance ground-return node; connects to system ground or transceiver VSS to complete both protection paths. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line BiSy architecture | Enables identical ±20 kV ESD protection on both CAN_H and CAN_L with no polarity dependency or external biasing. |

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 |
|---|---|---|---|
| STUSB4710QTR | Higher capacitance (8.5 pF at 5 V); unidirectional configuration requires separate ground-referenced layout. | Targeted at USB-C PD port protection; lacks AEC-Q101 qualification and CAN-specific clamping optimization. | Prefer VCAN36A2-HT5-G3-08 for CAN FD due to lower capacitance, BiSy symmetry, and automotive qualification. |
| ON Semiconductor NUP4202MR6T1G | Single-channel dual-diode array; requires two devices for dual-line protection; higher IR (0.1 μA) and VC (65 V at 1 A). | General-purpose ESD array; not optimized for CAN FD signal integrity or automotive thermal cycling. | VCAN36A2-HT5-G3-08 reduces component count, improves matching, and lowers clamping voltage for CAN FD compliance. |
Compared with STUSB4710QTR and NUP4202MR6T1G, the VCAN36A2-HT5-G3-08 delivers superior CAN FD signal fidelity through tighter capacitance matching, lower clamping voltage, and integrated dual-line symmetry-enabling single-device placement with guaranteed AEC-Q101 reliability across automotive temperature extremes.

FAQ
What is the primary function of the VCAN36A2-HT5-G3-08 in a CAN FD system?
The VCAN36A2-HT5-G3-08 serves as a bidirectional, dual-line ESD protection device placed directly at the CAN connector or transceiver interface. It clamps transient voltages-such as those from IEC 61000-4-2 ESD events-to safe levels (<58 V) while maintaining low capacitance (<4.6 pF at 5 V) to preserve signal integrity on CAN FD buses operating up to 5 Mbps. Its BiSy architecture ensures symmetric protection on both CAN_H and CAN_L lines without polarity constraints.
Does the VCAN36A2-HT5-G3-08 meet automotive qualification standards?
Yes, the VCAN36A2-HT5-G3-08 is fully qualified to AEC-Q101 Rev. G for automotive applications. It has passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and mechanical shock, and operates across a junction temperature range of −55 °C to +150 °C. This qualification confirms its suitability for under-hood, chassis, and battery management applications where reliability under thermal and mechanical stress is critical.
How does the DFN1110-3A package of the VCAN36A2-HT5-G3-08 benefit PCB layout?
The DFN1110-3A package (1.1 mm × 1.0 mm) reduces board space by over 50% compared to legacy SOT-23 solutions while maintaining a low 0.4 mm profile. Its three-terminal configuration-two line inputs (Pins 1 and 2) and one shared reference (Pin 3)-simplifies routing, minimizes parasitic inductance, and supports automated optical inspection (AOI). The e3 tin-plated terminations ensure robust solder joint reliability during lead-free reflow.
What is the significance of the 0.12 pF capacitance matching (dCD) specification for the VCAN36A2-HT5-G3-08?
The dCD ≤ 0.12 pF specification quantifies the maximum capacitance mismatch between the two internal protection paths (Pin1–Pin3 and Pin2–Pin3). Tight matching preserves differential signal balance on the CAN bus, preventing skew-induced bit errors-especially critical at CAN FD data rates above 2 Mbps. This level of matching exceeds typical industry benchmarks and directly supports compliance with ISO 11898-2 timing budgets.
Can the VCAN36A2-HT5-G3-08 be used in non-automotive CAN applications?
Yes, the VCAN36A2-HT5-G3-08 is widely deployed in industrial and commercial CAN systems-including PLCs, energy meters, and telematics units-where robust ESD immunity, low capacitance, and small footprint are required. Its ±20 kV IEC 61000-4-2 rating, −55 °C to +150 °C operation, and AEC-Q101 qualification make it especially valuable in harsh environments, even outside formal automotive programs.
