Product details
Overview
VCAN24A2-HT5-G3-08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) dual-line ESD protection diode in DFN1110-3A package, designed for CAN FD bus interfaces. It provides ±24 V working voltage, <6 pF capacitance at 5 V reverse bias, <0.05 μA leakage, and ±30 kV IEC 61000-4-2 ESD immunity - enabling robust signal integrity in automotive and industrial CAN networks.
For engineers reviewing the VCAN24A2-HT5-G3-08 datasheet, VCAN24A2-HT5-G3-08 pinout, VCAN24A2-HT5-G3-08 application, or VCAN24A2-HT5-G3-08 equivalent, key selection criteria include low clamping voltage (≤41 V at 2.5 A), matched line capacitance (ΔCD ≤0.12 pF), AEC-Q101 qualification, and DFN1110-3A footprint compatibility with high-density PCB layouts.
Technical Context
The VCAN24A2-HT5-G3-08 integrates two identical, symmetrical ESD protection paths (Pin 1–3 and Pin 2–3) in a single DFN1110-3A monolithic die. Each path features a low-capacitance silicon avalanche structure optimized for CAN FD's 5 Mbps+ signaling, with clamping behavior characterized per IEC 61000-4-5 (8/20 µs waveform) up to 100 W peak pulse power.
Its BiSy architecture eliminates polarity dependency, supporting bidirectional data flow without external biasing. The device operates across –55 °C to +150 °C junction temperature and meets AEC-Q101 stress test requirements including HBM Class H3B (>8 kV), making it suitable for under-hood automotive ECUs and industrial CAN nodes requiring long-term reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | ±24 V - matches nominal CAN FD bus voltage range and supports transceiver overvoltage tolerance |
| Clamping Voltage | ≤41 V at 2.5 A (8/20 µs) - limits transient-induced damage to downstream CAN transceivers |
| Capacitance | 5–6 pF at VR = 5 V - preserves signal edge integrity for >5 Mbps CAN FD data rates |
| Leakage Current | <0.05 μA at 24 V - avoids DC loading on CAN bus termination resistors |
| ESD Immunity | ±30 kV contact/air (IEC 61000-4-2) - exceeds automotive OEM ESD test requirements |
| Breakdown Voltage | 26.5–29.5 V at 1 mA - ensures stable conduction onset above normal bus swing |
| Package | DFN1110-3A (1.1 × 1.0 × 0.4 mm) - enables compact placement adjacent to CAN connectors or transceivers |
Pinout & Package
Package: DFN1110-3A - 3-terminal, bottom-side thermal pad, no leads, RoHS-compliant e3 tin plating, MSL Level 1, compatible with reflow per J-STD-020 (peak 260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Line 1 ESD path | Connects to CAN_H or CAN_L signal line 1; symmetrically clamps positive/negative transients to Pin 3 |
| Pin 2 | Anode of Line 2 ESD path | Connects to second CAN signal line (e.g., CAN_L or CAN_H); independent but matched path to Pin 3 |
| Pin 3 | Common cathode | Shared ground reference for both protection paths; must be connected to low-impedance system ground |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Symmetrical (BiSy) Protection | Enables single-device protection of differential CAN FD pairs without polarity assignment or external bias |
| Matched Line Capacitance | ΔCD ≤0.12 pF between lines - minimizes skew and maintains common-mode rejection in high-speed differential signaling |
| AEC-Q101 Qualified | Validated for automotive under-hood use including temperature cycling, humidity, and mechanical shock per AEC standard |
| Low-Leakage Avalanche Structure | IR < 0.05 μA at 24 V - prevents bus voltage droop and false dominant state triggering in idle CAN networks |
| AOI-Capable Marking | Dot-marked Pin 1 with date/type code - supports automated optical inspection in SMT production lines |
Applications
| Automotive CAN FD ECU | Industrial CANopen Node |
|---|---|
Use Scenario: Protection of CAN FD transceivers in engine control units exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Primary ESD clamp placed directly at connector interface, before transceiver input pins.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line CAN ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SEMTECH RCLAMP0524P.TCT | Higher capacitance (12 pF typ. at 0 V), lower clamping (32 V at 1 A), same DFN1110-3A footprint | Optimized for USB 2.0; less ideal for >2 Mbps CAN due to higher CD | Select when lower clamping priority outweighs speed requirement; verify CAN FD eye diagram compliance |
| ON SEMICONDUCTOR NUF2221MUTAG | Lower working voltage (±15 V), higher leakage (0.1 μA), same 2-line BiSy topology | Targeted at 12 V automotive infotainment; insufficient for 24 V CAN FD bus swing | Use only in 12 V systems with transceivers rated ≤18 V; not suitable for 24 V CAN FD |
Compared with RCLAMP0524P.TCT and NUF2221MUTAG, the VCAN24A2-HT5-G3-08 uniquely balances 24 V bus compatibility, sub-6 pF capacitance, and AEC-Q101 qualification - making it the only option among the three qualified for under-hood CAN FD nodes requiring simultaneous high-speed integrity and automotive-grade reliability.

FAQ
What is the maximum operating temperature for VCAN24A2-HT5-G3-08?
The VCAN24A2-HT5-G3-08 has a specified junction temperature range of –55 °C to +150 °C, fully compliant with AEC-Q101 requirements for under-hood automotive applications. This rating is validated through temperature cycling, high-temperature operating life, and storage tests - confirming reliable operation in engine control units and transmission control modules where ambient temperatures exceed 125 °C.
Does VCAN24A2-HT5-G3-08 support CAN FD data rates up to 5 Mbps?
Yes, the VCAN24A2-HT5-G3-08 supports CAN FD operation up to 5 Mbps due to its low and matched capacitance (5–6 pF at 5 V) and fast response time. Its clamping behavior - characterized via TLP and IEC 61000-4-5 testing - ensures minimal signal distortion during transients, preserving the eye diagram integrity required for high-speed CAN FD bit timing and error detection.
Is VCAN24A2-HT5-G3-08 pin-compatible with other Vishay CAN protection diodes like VCAN24A1?
No, VCAN24A2-HT5-G3-08 is not pin-compatible with VCAN24A1. The VCAN24A1 uses a SOT-23-3 package with different pin assignment (anode-cathode-anode), whereas VCAN24A2-HT5-G3-08 uses DFN1110-3A with Pin 1/Pin 2 as independent anodes and Pin 3 as shared cathode. PCB layout and footprint must be redesigned when substituting between these families.
What does the "-G3-08" suffix indicate in VCAN24A2-HT5-G3-08?
The "-G3-08" suffix denotes packaging and environmental coding: "G" indicates green (RoHS-compliant, lead-free) termination, "3" specifies 10,000 units per 7-inch reel (8 mm tape), and "-08" identifies the specific tape-and-reel configuration per Vishay's ordering matrix. This full part number ensures traceability to AEC-Q101 qualified production lots with e3 tin plating and MSL Level 1 handling.
Can VCAN24A2-HT5-G3-08 be used for non-CAN applications such as RS-485 or LIN?
The VCAN24A2-HT5-G3-08 may be used for RS-485 if the bus voltage remains within ±24 V and capacitance constraints (<6 pF) are acceptable for the data rate - though its BiSy symmetry and clamping profile are optimized for CAN FD. It is not recommended for LIN, which operates at 12 V and requires lower clamping voltage; dedicated LIN protectors like VBUS054 offer better performance at that voltage level.
