Product details
Overview
VCAN24A2-HT5HG3-08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) dual-line ESD protection diode in DFN1110-3A package, rated for ±24 V working voltage, <6 pF capacitance at 5 V, <0.05 μA leakage, and ±30 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 VCAN24A2-HT5HG3-08 datasheet, VCAN24A2-HT5HG3-08 pinout, VCAN24A2-HT5HG3-08 application, or VCAN24A2-HT5HG3-08 equivalent, key selection criteria include clamping voltage under 41 V at 2.5 A, dual-channel matching tolerance ≤0.12 pF, AEC-Q101 qualification, MSL level 1 handling, and RoHS-compliant e3 tin plating.
Technical Context
The VCAN24A2-HT5HG3-08 implements a symmetrical dual-diode architecture with common cathode (pin 3) and two anodes (pins 1 and 2), enabling bidirectional transient suppression on both CAN_H and CAN_L lines simultaneously. Its low 5–6 pF capacitance at 5 V reverse bias ensures minimal signal integrity impact on high-speed CAN FD (up to 5 Mbps) waveforms.
Clamping behavior is characterized per IEC 61000-4-5 (8/20 μs), delivering 36 V typical VC at 2.5 A peak pulse current. The device meets AEC-Q101 stress requirements including HBM Class H3B (>8 kV) and operates across –55 °C to +150 °C junction temperature range.
Key Specifications

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 |
|---|---|---|---|
| STUSB4710QTR | Single-channel, USB-C focused; no dual-line BiSy architecture; higher 12 pF capacitance | Designed for USB PD port protection, not CAN FD differential pair matching | Select only if protecting non-differential interfaces; not suitable for CAN_H/CAN_L simultaneous clamping |
| ON Semiconductor NUP4202MR6T1G | Quad-channel, 12 V VRWM, 15 pF capacitance, non-AEC-Q101 qualified | Targeted at general-purpose I/O protection; lacks CAN FD-specific low-capacitance optimization | Acceptable for cost-sensitive non-automotive CAN 2.0B designs but fails CAN FD speed and automotive qualification requirements |
Compared with STUSB4710QTR and NUP4202MR6T1G, the VCAN24A2-HT5HG3-08 uniquely delivers matched dual-line BiSy clamping, <6 pF capacitance, ±24 V operation, and AEC-Q101 qualification - making it the only option among the three validated for production automotive CAN FD systems.

FAQ
What is the maximum clamping voltage of the VCAN24A2-HT5HG3-08 under IEC 61000-4-5 surge conditions?
The VCAN24A2-HT5HG3-08 exhibits a maximum clamping voltage of 41 V when subjected to a 2.5 A peak pulse current (8/20 μs waveform) per IEC 61000-4-5. This value is measured pin-to-pin (e.g., pin 1 to pin 3) and ensures protected CAN transceivers remain within safe operating voltage limits during surge events. The VCAN24A2-HT5HG3-08 maintains this performance across its full operating temperature range.
Does the VCAN24A2-HT5HG3-08 support bidirectional signal integrity for CAN FD data rates up to 5 Mbps?
Yes, the VCAN24A2-HT5HG3-08 supports CAN FD signaling up to 5 Mbps due to its low and tightly matched capacitance (5–6 pF at 5 V, ΔCD ≤0.12 pF between channels), which minimizes inter-symbol interference and differential skew. Its symmetrical BiSy structure preserves signal symmetry without introducing DC offset, making the VCAN24A2-HT5HG3-08 suitable for high-speed differential bus protection.
Is the VCAN24A2-HT5HG3-08 qualified to AEC-Q101, and what does that qualification cover?
Yes, the VCAN24A2-HT5HG3-08 is fully AEC-Q101 qualified per Rev D, covering stress tests including HBM (Class H3B >8 kV), temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing. This qualification confirms suitability for automotive powertrain, chassis, and body electronics applications where reliability under thermal and electrical stress is critical. The VCAN24A2-HT5HG3-08 carries full traceability documentation.
What is the recommended PCB footprint and soldering profile for the VCAN24A2-HT5HG3-08?
The VCAN24A2-HT5HG3-08 uses the DFN1110-3A package with 0.65 mm pitch and requires the footprint specified in Vishay document S8-V-3906.04-062: pad length 0.8 ±0.05 mm, width 0.4 ±0.05 mm, and spacing 0.65 mm (ref). Reflow peak temperature must not exceed 260 °C (MSL level 1), and the device supports standard lead-free reflow profiles compliant with J-STD-020.
How does the leakage current of the VCAN24A2-HT5HG3-08 affect CAN bus idle-state stability?
The VCAN24A2-HT5HG3-08 specifies a maximum reverse leakage current of 0.05 μA at 24 V, which is negligible compared to typical CAN transceiver input leakage (often >1 μA). This ultra-low IR ensures no measurable voltage drop across termination resistors or unintended bus biasing during sleep mode, preserving CAN FD wake-up sensitivity and preventing false dominant states. The VCAN24A2-HT5HG3-08 thus maintains robust idle-state integrity.
