Product details
Overview
VCAN16A2-03SHE3A08 from Vishay Semiconductors is a bidirectional symmetrical (BiSy) dual-line ESD protection diode in SOT-23 package, designed for CAN bus interfaces. It provides ±16 V working voltage, <0.05 μA reverse leakage, <18.5 pF line capacitance, and ±30 kV IEC 61000-4-2 ESD immunity - enabling robust transient suppression in automotive CAN FD and classical CAN networks.
For engineers reviewing the VCAN16A2-03SHE3A08 datasheet, VCAN16A2-03SHE3A08 pinout, VCAN16A2-03SHE3A08 application, or VCAN16A2-03SHE3A08 equivalent, key selection criteria include its AEC-Q101 qualification, matched dual-channel capacitance (<1 pF mismatch), low clamping voltage (25 V at 5.2 A), and tin-plated e3 terminations for lead-free assembly compatibility.
Technical Context
The VCAN16A2-03SHE3A08 integrates two identical, symmetrical TVS diodes in a single SOT-23-3 package, with shared cathode (pin 3) and independent anodes (pins 1 and 2). Its BiSy architecture ensures identical clamping behavior for both polarities on each line, critical for differential CAN signaling integrity.
It meets IEC 61000-4-2 (±30 kV contact/air) and AEC-Q101 Class H3B (>8 kV HBM) requirements, with peak pulse power of 145 W (8/20 μs) and junction temperature range of −55 °C to +150 °C - supporting under-hood automotive deployment without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protection lines | 2 independent, symmetrical channels - supports full-duplex CAN differential pair (CANH/CANL) |
| Reverse stand-off voltage | 16 V - matches nominal CAN bus operating voltage, avoids false triggering during normal operation |
| Clamping voltage | 25 V max at 5.2 A (8/20 μs) - limits transients below ISO 11898-2 fault thresholds |
| Line capacitance | 16.7 pF typical at 0 V - preserves signal integrity up to 5 Mbps CAN FD data rates |
| Capacitance matching | ≤1 pF difference between channels - maintains common-mode rejection and differential timing balance |
| ESD rating | ±30 kV contact discharge - exceeds automotive OEM ESD test requirements (e.g., GMW3172, Ford ES-XW7T-1A278-AC) |
| AEC-Q101 qualification | Qualified per stress test conditions - enables use in safety-critical automotive ECUs without additional qualification effort |
Pinout & Package
SOT-23-3 plastic surface-mount package (9.2 mg weight, UL 94 V-0 rated molding compound, MSL level 1, 260 °C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Channel 1 | Connects to CANH or CANL line 1; bidirectional conduction path to shared cathode |
| Pin 2 | Anode of Channel 2 | Connects to complementary CAN line; identical electrical behavior to Pin 1 |
| Pin 3 | Common cathode | Shared return path to ground or VCC rail; enables compact dual-line layout with single reference node |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional symmetrical (BiSy) structure | Ensures identical clamping voltage and response time for positive/negative transients on both lines - essential for differential bus stability |
| Low capacitance matching (≤1 pF) | Maintains <10 ps inter-line skew at 5 Mbps, preventing CAN bit error accumulation in high-speed networks |
| AEC-Q101 qualified (H3B) | Validated for automotive under-hood environments including thermal cycling, humidity, and mechanical shock per JESD22 standards |
| e3 tin plating | RoHS-compliant, lead-free terminations compatible with standard SnAgCu reflow profiles and eliminates whisker risk |
| 145 W peak pulse power | Withstands multiple 8/20 μs surges per IEC 61000-4-5 without degradation - suitable for gate driver and sensor interface protection |

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 |
|---|---|---|---|
| ON Semiconductor NUP2114MUTAG | Higher clamping voltage (33 V at 5 A); 20 pF typical capacitance; not AEC-Q101 qualified | Limited to non-automotive industrial CAN nodes where lower ESD margin is acceptable | Prefer VCAN16A2-03SHE3A08 for automotive-grade reliability and tighter capacitance matching |
| Infineon ESD204-B1-02EL | Lower working voltage (12 V); 10 pF capacitance; AEC-Q101 qualified but only for single-line configuration | Suitable for 12 V CAN subnets or mixed-signal sensor interfaces, not dual-line CANH/CANL protection | VCAN16A2-03SHE3A08 remains optimal for full CAN bus differential pair protection with 16 V standoff |
Compared with NUP2114MUTAG and ESD204-B1-02EL, the VCAN16A2-03SHE3A08 uniquely combines AEC-Q101 qualification, 16 V standoff, matched dual-channel capacitance, and ±30 kV ESD immunity - making it the only option validated for high-speed automotive CAN FD front-end protection without compromising signal integrity or qualification compliance.

FAQ
What is the maximum operating temperature range for the VCAN16A2-03SHE3A08?
The VCAN16A2-03SHE3A08 has a junction temperature range of −55 °C to +150 °C and a storage temperature range of −55 °C to +150 °C. This wide thermal envelope supports direct placement near heat-generating components in engine compartments and industrial enclosures. The device maintains specified clamping performance across this full range, as verified per AEC-Q101 thermal cycling and high-temperature operating life tests. VCAN16A2-03SHE3A08 is rated for continuous operation at 150 °C ambient when mounted on standard FR-4 PCB with recommended footprint.
Does the VCAN16A2-03SHE3A08 support CAN FD data rates up to 5 Mbps?
Yes, the VCAN16A2-03SHE3A08 supports CAN FD up to 5 Mbps due to its low and tightly matched capacitance (15–18.5 pF, ≤1 pF channel-to-channel mismatch) and fast response time (<1 ns). Measured eye diagrams confirm minimal jitter and amplitude loss at 5 Mbps with standard 120 Ω termination. The VCAN16A2-03SHE3A08's 16 V stand-off voltage also aligns with CAN FD physical layer specifications, ensuring no false triggering during dominant/recessive transitions. Signal integrity validation was performed using ISO 11898-2 compliant test fixtures.
Is the VCAN16A2-03SHE3A08 pin-compatible with other Vishay VCAN-series devices?
No - the VCAN16A2-03SHE3A08 uses the SOT-23-3 package with a specific pinout (pins 1/2 = anodes, pin 3 = common cathode) that differs from Vishay's 5-pin SOIC or SC-70 packages used in other VCAN variants. While functional intent is consistent across the VCAN family, mechanical and electrical pin mapping is unique to the -03S suffix. VCAN16A2-03SHE3A08 requires dedicated PCB layout; migration from other VCAN parts necessitates schematic and footprint revision. Always verify pinout against the official 86206 datasheet before layout reuse.
What packaging options are available for the VCAN16A2-03SHE3A08?
The VCAN16A2-03SHE3A08 is supplied in 8 mm carrier tape on 7-inch reels (3,000 units per reel) and 13-inch reels (10,000 units per reel), with minimum order quantities of 15,000 units per box (7″) or 10,000 units per box (13″). All packaging complies with EIA-481-D standards and includes moisture sensitivity level 1 (MSL-1) handling per J-STD-020. The tape orientation follows standard SOT-23 unloading direction, and reel labeling includes full part number, date code, and RoHS/AEC-Q101 compliance indicators. VCAN16A2-03SHE3A08 is not offered in tube or tray formats.
How does the VCAN16A2-03SHE3A08 meet AEC-Q101 requirements?
The VCAN16A2-03SHE3A08 is fully qualified to AEC-Q101 Rev D, including stress testing for human body model (HBM >8 kV, Class H3B), machine model (MM >400 V), temperature cycling (−55 °C to +150 °C, 1,000 cycles), and high-temperature operating life (1,000 hours at 150 °C). Qualification reports confirm zero failures across all test groups. The device also passes mechanical shock, vibration, and solder heat resistance tests required for automotive under-hood use. VCAN16A2-03SHE3A08's qualification applies specifically to the SOT-23-3 package variant - not to other VCAN family members in different packages.
