Product details
Overview
DUP2105SOQ from Diodes Incorporated is a dual-channel automotive-grade TVS diode array designed for CAN bus line protection in harsh environments. It provides ±30kV ESD immunity (IEC 61000-4-2), clamps transients to ≤44V at 8A peak pulse current, and features 24V reverse standoff voltage with ≤30pF channel capacitance - enabling robust signal integrity in high-speed CAN FD and legacy CAN networks.
For engineers reviewing the DUP2105SOQ datasheet, DUP2105SOQ pinout, DUP2105SOQ application, or DUP2105SOQ equivalent, key selection criteria include its AEC-Q101 qualification, SOT23-6 package footprint, differential ESD protection per line, low leakage (<100nA at 24V), and thermal derating behavior up to +150°C ambient.
Technical Context
This device implements a dual unidirectional TVS structure optimized for bidirectional CAN bus signaling, where each channel independently clamps positive transients to ≤44V (at 8A) while maintaining <30pF input capacitance to minimize signal distortion. Its 26.2V breakdown voltage ensures reliable triggering before CAN transceiver damage thresholds.
The SOT23-6 package supports surface-mount integration directly at connector or transceiver I/O pins, with thermal resistance of 417°C/W enabling operation across -65°C to +150°C without external heatsinking - critical for under-hood automotive modules and industrial control nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Breakdown Voltage (VBR) | 26.2 V min - Triggers clamping before transceiver overvoltage damage occurs |
| Clamping Voltage (IPP = 8A) | 44 V max - Limits transient stress on downstream CAN transceiver I/O |
| Peak Pulse Power | 350 W per line - Handles ISO 7637-2 pulse 1/2/5a surges without degradation |
| ESD Rating (IEC 61000-4-2) | ±30 kV contact/air - Meets automotive EMC test requirements for module-level validation |
| Channel Capacitance | 30 pF max - Preserves CAN signal edge integrity up to 5 Mbps (CAN FD) |
| Leakage Current | 100 nA max at 24V - Prevents bus loading and false wake-up in sleep modes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line CAN bus protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NUP2114MR6T1G | Lower clamping voltage (33V @ 8A), higher capacitance (65pF), same SOT23-6 package | Better for 12V systems with tighter voltage margins; less suitable for CAN FD due to bandwidth limitation | Select when prioritizing lower clamping over signal integrity at >1 Mbps |
| SM712 | Bidirectional configuration, higher power rating (600W), SO-8 package, 100pF capacitance | Requires board redesign; suited for legacy CAN only; not AEC-Q101 qualified | Choose only for cost-sensitive non-automotive designs where footprint flexibility exists |
Compared with NUP2114MR6T1G and SM712, DUP2105SOQ delivers optimal balance of low capacitance, automotive qualification, and precise clamping for modern CAN FD implementations - especially where PCB space, thermal constraints, and ESD robustness are co-prioritized.

FAQ
What is the maximum operating temperature for DUP2105SOQ?
The DUP2105SOQ is rated for junction and storage temperatures from -65°C to +150°C. Its thermal resistance (RθJA = 417°C/W) allows continuous operation at +125°C ambient when mounted on standard FR-4 PCB with 2oz copper, verified per Diodes' package outline documentation.
Does DUP2105SOQ require external biasing or series impedance?
No. The DUP2105SOQ operates passively as a shunt TVS device and requires no external bias, current-limiting resistors, or supporting circuitry. It connects directly between CAN_H/CAN_L lines and ground/VCC, relying solely on its intrinsic avalanche characteristics for clamping.
How does the dual-channel configuration protect differential CAN signaling?
Each channel (pins 1–3 for CAN_H, pins 4–6 for CAN_L) provides independent unidirectional clamping: anode-to-VCC for positive transients and cathode-to-GND for negative transients. This preserves differential mode integrity while suppressing common-mode surges without introducing DC offset or skew.
Is DUP2105SOQ compatible with CAN FD physical layer requirements?
Yes. With ≤30pF channel capacitance and sub-1ns response time, it meets ISO 11898-2:2016 requirements for CAN FD up to 5 Mbps. Its low capacitance avoids signal reflection and maintains eye diagram compliance when placed within 5mm of the transceiver I/O pins.
