Product details
Overview
PESD2CANFD36LQB-QZ from Nexperia is a bidirectional ESD protection diode in a DFN1110D-3 (SOT8015) package, designed for dual-line CAN-FD bus protection in automotive 24 V systems. It delivers 36 V reverse standoff voltage, 42 V typical clamping at 1 A, and 10 pF capacitance - enabling low-distortion transient suppression on high-speed differential buses while meeting AEC-Q101 qualification.
For engineers reviewing the PESD2CANFD36LQB-QZ datasheet, PESD2CANFD36LQB-QZ pinout, PESD2CANFD36LQB-QZ application, or PESD2CANFD36LQB-QZ equivalent, this device is selected specifically for CAN-FD physical layer ESD hardening where low clamping voltage, tight capacitance matching (<0.5%), and side-wettable flanks for automated optical inspection are critical design requirements.
Technical Context
This dual-cathode ESD array integrates two matched TVS diodes sharing a common cathode (Pin 3), forming a symmetrical bidirectional clamp across CANH–CC and CANL–CC paths. Its TLP-measured clamping voltage of 52 V at 16 A (100 ns) and dynamic resistance of 1 Ω ensure fast energy diversion during ISO 10605 contact discharge events.
The device operates within –55 °C to +150 °C ambient range and supports IEC 61000-4-2 (±20 kV), ISO 7637-2 pulse 3a/3b (±300 V), and pulse 2a (65 V), making it suitable for harsh automotive transients without degrading signal integrity on 5 Mbps CAN-FD links.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 36 V reverse standoff voltage - maintains high-impedance state during normal CAN-FD bus operation up to ±36 V common-mode swing. |
| VCL @ 1 A | 42 V typical clamping voltage - limits transient overvoltage to safe levels below CAN transceiver absolute maximum ratings. |
| Cd | 10 pF diode capacitance - minimizes signal rise-time degradation and reflection on 5 Mbps CAN-FD differential pairs. |
| ΔCd/Cd | ±0.5 % capacitance matching - ensures balanced differential impedance and common-mode rejection across both protected lines. |
| ESD Rating | 20 kV per IEC 61000-4-2 and ISO 10605 - withstands repeated contact discharge without parametric shift or failure. |
| IPP | 2.9 A peak pulse current (8/20 µs) - handles surge energy from ISO 7637-2 pulses without thermal runaway. |
| Rdyn | 1 Ω dynamic resistance - enables rapid voltage clamping response with minimal overshoot during nanosecond-scale ESD events. |
Pinout & Package
DFN1110D-3 (SOT8015) ultra-small leadless package: 1.1 mm × 1.0 mm × 0.48 mm body, 0.65 mm pitch, side-wettable flanks for solder-joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Connects to CANH line; forms clamping path to common cathode during positive transients on CANH. |
| 2 | K2 (cathode of diode 2) | Connects to CANL line; forms clamping path to common cathode during positive transients on CANL. |
| 3 | CC (common cathode) | Shared return node tied to chassis or local ground plane; completes bidirectional clamp for both differential lines. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low clamping voltage | 42 V typical at 1 A - reduces stress on downstream CAN transceivers during ESD events, extending system-level robustness. |
| Matched low capacitance | 10 pF ±0.5 % between channels - preserves differential signal fidelity and timing skew on high-speed CAN-FD buses. |
| Side-wettable flanks | SOT8015 package with visible solder fillets - enables automated optical inspection (AOI) of solder joints in automotive PCB assembly. |
| AEC-Q101 qualified | Qualified for automotive use per stress test standard - guarantees reliability under temperature cycling, humidity, and mechanical shock. |
| Dual-line protection | Single-package dual-diode architecture with shared cathode - eliminates layout mismatch and saves board space vs. discrete solutions. |
Applications
| Automotive CAN-FD Bus Protection | 24 V Truck Network ESD Hardening |
|---|---|
Use Scenario: Protecting high-speed CAN-FD communication between ADAS ECUs and domain controllers in electric vehicles. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector interface to clamp ESD before reaching CAN transceiver input pins. Use Value: Enables reliable 5 Mbps data transmission by limiting clamping overshoot to ≤42 V, staying within TJA1145 transceiver's 58 V abs max rating. |
Use Scenario: Safeguarding diagnostic and control bus lines in heavy-duty truck electronics exposed to frequent operator-handling ESD. IC Role / Device Role / Timing Role: Dual-channel ESD protector mounted adjacent to OBD-II connector, shunting transients to chassis ground via Pin 3. Use Value: Survives repeated 20 kV contact discharges per ISO 10605 while maintaining <1 nA leakage at 36 V - preventing false wake-up in low-power sleep modes. |
| FlexRay Physical Layer Protection | SENT Sensor Interface Transient Suppression |
Use Scenario: Shielding FlexRay bus nodes in powertrain control modules against ESD-induced bit errors during vehicle assembly. IC Role / Device Role / Timing Role: Low-capacitance clamp on FRAY+ and FRAY− lines, leveraging matched Cd to preserve 10 Mbps differential signaling integrity. Use Value: 10 pF capacitance and ±0.5 % matching reduce signal asymmetry, keeping eye diagram jitter below 15% UI at 10 Mbps. |
Use Scenario: Protecting SENT-compliant pressure and temperature sensors in engine bay environments subject to cable coupling transients. IC Role / Device Role / Timing Role: Single-device dual-line clamp on SENT signal and return lines, using common cathode to minimize ground loop area. Use Value: Clamps ISO 7637-2 pulse 2a (65 V) to <52 V within 100 ns, preventing sensor output saturation and erroneous fault reporting. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-line automotive ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDALC6V1-1M2 | Unidirectional configuration; 6.1 V VRWM; higher 15 pF capacitance | Requires separate ground-referenced placement per line; unsuitable for differential bus clamping | Select only when protecting single-ended signals like LIN or analog sensor inputs |
| TPD2E001DRYR | 2-channel unidirectional; 5 V VRWM; 12 pF capacitance; not AEC-Q101 qualified | Lacks automotive qualification and pulse 3a/3b surge rating; limited to infotainment subsystems | Use only in non-safety-critical cabin modules with lower ESD severity requirements |
Compared with ESDALC6V1-1M2 and TPD2E001DRYR, PESD2CANFD36LQB-QZ uniquely combines bidirectional 36 V standoff, matched 10 pF capacitance, AEC-Q101 qualification, and SOT8015 side-wettable flanks - making it the only option validated for production CAN-FD bus protection in powertrain and ADAS domains.

FAQ
What is the maximum operating temperature for PESD2CANFD36LQB-QZ?
The device supports junction temperatures up to 150 °C and ambient operating range from –55 °C to +150 °C, verified per AEC-Q101 thermal cycling and high-temperature operating life tests. This enables direct placement near powertrain ECUs and under-hood modules without derating.
Can PESD2CANFD36LQB-QZ protect both CANH and CANL simultaneously?
Yes - its dual-diode structure with shared cathode (Pin 3) provides symmetrical bidirectional clamping across both lines. During a positive ESD event on CANH, current flows from Pin 1 to Pin 3; during negative events on CANL, current flows from Pin 3 to Pin 2 - fully protecting the differential pair.
Is the 10 pF capacitance measured differentially or line-to-ground?
The 10 pF value is measured line-to-ground: capacitance from Pin 1 to Pin 3 and Pin 2 to Pin 3, each specified at 1 MHz and 0 V bias. The ±0.5 % matching (ΔCd/Cd) confirms near-identical values between these two paths, critical for differential signal integrity.
Does PESD2CANFD36LQB-QZ require external grounding components?
No external components are required - Pin 3 (CC) must be connected directly to a low-inductance chassis or local ground plane. Layout guidelines mandate minimizing trace length to ground and avoiding shared return paths to maintain clamping effectiveness during sub-nanosecond ESD events.
