Product details
Overview
PESD2CAN,215 from Nexperia is a dual-channel automotive-grade ESD protection diode in SOT23 package, designed specifically for bidirectional transient suppression on CANH and CANL lines. It delivers 230 W peak pulse power (8/20 µs), clamps at 41 V under 5 A surge, and provides 30 kV IEC 61000-4-2 contact ESD protection - enabling robust CAN bus interface protection in vehicle body control modules.
For engineers reviewing the PESD2CAN,215 datasheet, PESD2CAN,215 pinout, PESD2CAN,215 application, or PESD2CAN,215 equivalent, key selection criteria include reverse standoff voltage (24 V), diode capacitance (25–30 pF), ultra-low leakage (<1 nA), AEC-Q101 qualification, and dual-cathode common-anode topology for differential CAN line protection.
Technical Context
The PESD2CAN,215 integrates two identical ESD protection diodes in a single SOT23-3 package with shared cathode (Pin 3) and independent anodes (Pins 1 and 2), forming a bidirectional clamp configuration per CAN line. Its low 25–30 pF capacitance ensures minimal signal integrity impact on high-speed CAN (up to 1 Mbps) and fault-tolerant CAN buses.
It meets IEC 61000-4-2 Level 4 (±30 kV contact), IEC 61000-4-5 (5 A, 8/20 µs), and AEC-Q101 stress requirements, with junction temperature rated to 150 °C and ambient operation from −55 °C to +150 °C - confirming suitability for under-hood and chassis-mounted automotive electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 24 V reverse standoff voltage - blocks normal CAN bus common-mode voltages while remaining non-conductive during 0–24 V operation. |
| VCL @ 5 A | 41 V clamping voltage - limits transient overvoltage to safe levels for downstream CAN transceivers during 8/20 µs surges. |
| Cd | 25–30 pF capacitance at 1 MHz - preserves CAN signal edge integrity and avoids bit timing distortion in high-speed networks. |
| IRM | <1 nA reverse leakage at 24 V - prevents parasitic current draw that could disrupt biasing or sleep-mode current budgets. |
| PPP | 230 W peak pulse power (8/20 µs) - sustains energy dissipation across both channels without thermal runaway. |
| ESD Rating | 30 kV IEC 61000-4-2 contact discharge - exceeds automotive OEM requirements for connector-level ESD immunity. |
| AEC-Q101 | Qualified per Stress Test Qualification for Discrete Semiconductors - validated for lifetime reliability in automotive environments. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package, 3-pin, 1.9 mm × 1.1 mm footprint, 0.95 mm height, with gull-wing leads and standard 0.95 mm pitch. RoHS-compliant, halogen-free, and qualified for reflow and wave soldering per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | Connects to CANH line; forms first ESD path to common cathode (Pin 3) during positive transients. |
| 2 | Anode of Diode 2 | Connects to CANL line; enables independent clamping for differential CAN bus protection. |
| 3 | Common Cathode | Shared return path to ground or chassis; establishes symmetrical bidirectional clamping for both lines. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line CAN protection | Single SOT23 device protects both CANH and CANL with matched characteristics - reduces PCB area and BOM count vs. discrete diodes. |
| Low capacitance | 25–30 pF ensures <1% signal rise-time degradation on 1 Mbps CAN, preserving bus timing margins and noise immunity. |
| Ultra-low leakage | <1 nA at 24 V VRWM eliminates measurable current drain in battery-sensitive applications like gateway sleep modes. |
| Automotive qualification | AEC-Q101 compliance confirms performance across −55 °C to +150 °C, including temperature cycling, humidity, and mechanical shock testing. |
| IEC 61000-4-5 surge rating | 5 A (8/20 µs) surge capability per line supports ISO 7637-3 and ISO 16750-2 transient immunity requirements for 12 V systems. |
Applications
| Body Control Module (BCM) | Powertrain Gateway |
|---|---|
|
Use Scenario: Protecting CAN communication between door modules, lighting controllers, and central BCM in 12 V vehicle architectures. IC Role / Device Role / Timing Role: Bidirectional transient suppressor placed at CAN connector entry point, clamping ESD and load-dump-induced spikes before they reach the transceiver. Use Value: Prevents latch-up or permanent damage to CAN transceivers during assembly handling or service port connection, maintaining network uptime and diagnostic access. |
Use Scenario: Shielding gateway MCU's dual-CAN interfaces connecting engine control unit (ECU) and infotainment domain over fault-tolerant CAN. IC Role / Device Role / Timing Role: Differential line protector ensuring signal integrity during ignition transients and alternator ripple events in high-noise powertrain zones. Use Value: Enables reliable cross-domain messaging without added filtering components, reducing latency and board space versus RC+TVS solutions. |
| Advanced Driver Assistance Systems (ADAS) Camera Hub | Electric Vehicle (EV) Battery Management Interface |
|
Use Scenario: Securing CAN-FD links between surround-view cameras and domain controller in ADAS sensor fusion units. IC Role / Device Role / Timing Role: Low-capacitance ESD guard for high-speed CAN physical layer, minimizing jitter and bit error rate under ESD stress. Use Value: Maintains frame synchronization and image timestamp accuracy by preventing transient-induced CAN arbitration errors or bus-off states. |
Use Scenario: Safeguarding isolated CAN communication between battery pack BMS and vehicle controller in 400 V/800 V EV platforms. IC Role / Device Role / Timing Role: Transient barrier between high-voltage domain and low-voltage CAN PHY, meeting reinforced isolation creepage/clearance requirements. Use Value: Eliminates need for additional opto-isolator-level surge protection, lowering system cost while retaining ASIL-B functional safety compliance. |
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 |
|---|---|---|---|
| TPD2E001DRYR | Lower PPP (120 W), higher Cd (45 pF), same SOT-23-3 pinout but single-diode architecture requiring external common node. | Not AEC-Q101 qualified; limited to consumer/industrial CAN nodes without automotive temperature or reliability demands. | Prefer where cost sensitivity outweighs automotive qualification and surge margin. |
| ESDALC6V1-1U2 | Higher VRWM (33 V), lower VCL (36 V @ 5 A), 15 pF capacitance, but only 100 W PPP and no AEC-Q101 certification. | Designed for USB/IO protection; lacks CAN-specific layout optimization and surge test validation for automotive bus topologies. | Select when ultra-low capacitance is critical and surge exposure is below ISO 16750-2 Level III. |
Compared with TPD2E001DRYR and ESDALC6V1-1U2, PESD2CAN,215 uniquely combines AEC-Q101 qualification, 230 W per-line surge rating, and matched dual-diode symmetry - making it the only drop-in solution for production automotive CAN nodes requiring full OEM compliance.

FAQ
What is the maximum operating temperature for PESD2CAN,215?
The PESD2CAN,215 has a maximum junction temperature of 150 °C and operates across an ambient temperature range of −55 °C to +150 °C. Its thermal resistance (RthJA) is 350 K/W in standard JEDEC PCB layout, enabling use in under-hood locations without forced cooling.
Does PESD2CAN,215 support high-speed CAN FD?
Yes - its 25–30 pF capacitance and sub-1 ns response time ensure minimal signal distortion on CAN FD buses up to 5 Mbps. Layout best practices (short traces, ground plane proximity) maintain eye diagram integrity per ISO 11898-2.
How is the common cathode (Pin 3) connected in typical CAN protection circuits?
In standard implementation, Pin 3 connects directly to chassis ground or a low-inductance system ground plane - not to signal ground - to provide a dedicated low-impedance path for ESD/surge currents, preventing ground bounce in sensitive transceiver ICs.
Is PESD2CAN,215 compatible with lead-free reflow profiles?
Yes - it is qualified for standard lead-free reflow per J-STD-020, with peak temperature tolerance up to 260 °C for 30 seconds. The SOT23 package uses matte tin plating and passes MSL-1 moisture sensitivity classification without dry-pack requirements.
