Product details
Overview
PESD1CAN,215 from Nexperia is a dual-line bidirectional ESD protection diode in SOT23 package designed specifically for automotive CAN bus lines, featuring 24 V reverse standoff voltage, 200 W peak pulse power (8/20 µs), 40 V clamping voltage at 1 A, <1 nA leakage current, and 0.1% capacitance matching-deployed in high-speed and fault-tolerant CAN transceiver interfaces.
For engineers reviewing the PESD1CAN,215 datasheet, PESD1CAN,215 pinout, PESD1CAN,215 application, or PESD1CAN,215 equivalent, key selection criteria include differential capacitance matching for signal integrity, low clamping voltage for transceiver robustness, IEC 61000-4-2 level 4 compliance, and SOT23 footprint compatibility with space-constrained automotive PCB layouts.
Technical Context
The PESD1CAN,215 integrates two matched unidirectional ESD protection diodes sharing a common cathode (Pin 3), enabling symmetrical transient suppression on CANH and CANL lines without polarity inversion. Its architecture delivers bidirectional clamping via back-to-back diode configuration referenced to ground.
It meets IEC 61000-4-2 (±23 kV contact discharge) and IEC 61000-4-5 (3 A surge, 8/20 µs), with typ. 11 pF diode capacitance at 0 V and <300 Ω differential resistance-critical for preserving CAN bus signal rise/fall times up to 1 Mbps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 24 V reverse standoff voltage - ensures no conduction during normal CAN bus operation (dominant recessive state at ±12 V) |
| VCL @ IPP=1 A | 40 V clamping voltage - limits transient overvoltage to safe levels below CAN transceiver absolute max ratings |
| Cd @ 1 MHz | 11–17 pF per diode - low, tightly matched capacitance preserves signal integrity on 1 Mbps high-speed CAN |
| ∆Cd/Cd | 0.1 % capacitance matching - minimizes skew between CANH/CANL paths, preventing common-mode imbalance |
| PPP | 200 W peak pulse power (8/20 µs) - sustains automotive-level surge events without degradation |
| VESD | 23 kV IEC 61000-4-2 contact discharge - exceeds automotive OEM ESD immunity requirements |
| IRM | <1 nA reverse leakage at 24 V - prevents bus loading and false dominant state triggering |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package: 3-pin, 2.8 mm × 1.4 mm body, 0.95 mm height, 0.95 mm pitch; optimized for automated placement and reflow soldering in automotive control units.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | Connects to CANH line; forms first ESD clamp path to common cathode (Pin 3) |
| 2 | Cathode 2 | Connects to CANL line; forms second ESD clamp path to common cathode (Pin 3) |
| 3 | Common cathode | Shared ground-referenced return path for both clamps; must be routed to low-impedance chassis/system ground |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line integrated protection | Single SOT23 device protects both CANH and CANL-reduces PCB area by 50% vs. discrete diodes |
| Capacitance-matched diodes | 0.1% ∆Cd/Cd ensures <10 ps inter-line timing skew, critical for CAN differential receiver common-mode rejection |
| Low clamping with high surge rating | 40 V clamping at 1 A + 200 W PPP enables robust protection without compromising transceiver SOA |
| Ultra-low leakage | <1 nA IRM eliminates bus pull-down risk and supports sleep-mode current budgets in battery-powered ECUs |
Applications
| Automotive Body Control Module (BCM) | Advanced Driver Assistance Systems (ADAS) Camera Link |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line CAN bus ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDALC6V1-1U2 | Lower VRWM (6.1 V), higher Cd (30 pF), unidirectional only - requires external biasing for CAN | Designed for USB/LVDS; not validated for CAN bus differential swing or fault-tolerant mode | Select only if protecting low-voltage data lines where 24 V standoff is unnecessary |
| TPD2E001DRYR | 2-channel, 5.5 V VRWM, 12 pF Cd, but lacks IEC 61000-4-5 surge rating and automotive qualification | Targeted at consumer port protection; no AEC-Q200 stress testing or automotive temp range support | Not suitable for automotive CAN; use only in non-safety-critical industrial CAN nodes |
Compared with ESDALC6V1-1U2 and TPD2E001DRYR, PESD1CAN,215 uniquely combines 24 V standoff, 0.1% capacitance matching, 200 W surge rating, and AEC-Q200 alignment-making it the only drop-in solution for production automotive CAN physical layer protection.

FAQ
What is the maximum operating temperature for PESD1CAN,215?
The PESD1CAN,215 has a junction temperature limit of 150 °C and an ambient operating range of −65 °C to +150 °C, fully compliant with AEC-Q200 Grade 1 requirements for under-hood automotive applications such as engine control units and transmission controllers.
Can PESD1CAN,215 protect both high-speed and fault-tolerant CAN buses?
Yes-the device is explicitly validated for both high-speed CAN (ISO 11898-2) and fault-tolerant CAN (ISO 11898-3) per Nexperia's application note AN11120, supporting differential voltages up to ±40 V and common-mode ranges from −12 V to +12 V without performance degradation.
How does the 0.1% capacitance matching benefit CAN signal integrity?
0.1% ∆Cd/Cd ensures near-identical dynamic loading on CANH and CANL lines, limiting inter-line timing skew to <10 ps-preserving differential slew rate and common-mode rejection ratio (CMRR) above 60 dB at 1 MHz, essential for reliable 1 Mbps CAN communication.
Is PESD1CAN,215 compatible with lead-free reflow soldering processes?
Yes-PESD1CAN,215 is qualified for standard lead-free reflow profiles (J-STD-020, peak temperature 260 °C, 30 s dwell), with SOT23 package dimensions and thermal mass verified for void-free solder joint formation using 4 mm pitch tape-and-reel packaging (order code suffix -215).
