Product details
Overview
PESD2CANFD36UT-QR from Nexperia is a dual-channel automotive-grade ESD protection diode in SOT23 package, designed for bidirectional transient suppression on CAN-FD and FlexRay bus lines. It features 36 V reverse standoff voltage, 4.3 pF typical capacitance, 48 V clamping at 1 A, 15 kV IEC 61000-4-2 ESD rating, and AEC-Q101 qualification - deployed in 24 V truck network interfaces.
For engineers reviewing the PESD2CANFD36UT-QR datasheet, PESD2CANFD36UT-QR pinout, PESD2CANFD36UT-QR application, or PESD2CANFD36UT-QR equivalent, this page delivers verified electrical parameters, validated SOT23 terminal mapping, automotive bus-specific use cases, and qualified alternative options with documented functional trade-offs.
Technical Context
This device implements a common-cathode dual-diode architecture (K1/K2 → CC), enabling symmetrical clamping on two independent signal lines referenced to a shared ground return path. Its low 4.3 pF capacitance ensures minimal signal integrity impact on high-speed CAN-FD (up to 5 Mbps) and SENT data links.
The 36 V VRWM supports 24 V board net operation with margin against load dump transients, while 65 V clamping at 16 A (TLP) provides robust surge immunity per ISO 10605 and IEC 61000-4-5. Dynamic resistance of 1.3 Ω ensures fast response under sub-nanosecond ESD events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 36 V - Withstands continuous 24 V automotive bus voltage with 50% headroom against transients |
| VCL @ 1 A | 48 V - Limits peak voltage during ESD strike to protect downstream CAN transceiver I/O |
| Cd | 4.3 pF - Enables <5% signal rise-time degradation on 5 Mbps CAN-FD differential pairs |
| ESD Rating | ±15 kV IEC 61000-4-2 - Meets OEM-level ESD immunity requirements for vehicle harness connectors |
| IPP | 1.5 A (8/20 µs) - Handles repetitive surges in engine control module power domains |
| AEC-Q101 | Qualified - Validated for -55 °C to +150 °C junction operation in under-hood ECUs |
Pinout & Package
SOT23 plastic surface-mounted package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body height. RoHS-compliant, halogen-free, and qualified for reflow and wave soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Connects to first protected line (e.g., CANH); clamps positive transients to CC |
| 2 | K2 (cathode of diode 2) | Connects to second protected line (e.g., CANL); clamps positive transients to CC |
| 3 | CC (common cathode) | Shared return path to system ground; enables compact dual-line layout without discrete grounds |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line common-cathode topology | Reduces PCB footprint by 40% vs. two discrete TVS diodes; eliminates inter-channel ground loop |
| 4.3 pF matched capacitance (ΔCd/Cd ≤ 0.5%) | Maintains CAN-FD differential skew <100 ps across temperature (-40 °C to +125 °C) |
| 1.3 Ω dynamic resistance | Enables <1 ns response to ESD pulses, limiting energy transfer before transceiver latch-up |
| AEC-Q101 qualification | Validated for 1000-cycle temperature cycling (-55 °C ↔ +150 °C) and 1000-hour HTRB life test |

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 |
|---|---|---|---|
| ON Semiconductor NUP2114 | Higher 6.5 pF capacitance; 33 V VRWM; same SOT23-3 package | Marginally suitable for 12 V CAN systems only; not rated for 24 V truck networks | Select when cost sensitivity outweighs 24 V compatibility and high-speed timing needs |
| Infineon ESD224-BI | Lower 3.5 pF capacitance; 30 V VRWM; AEC-Q101 qualified; SOT23-3 | Limited to 12 V systems; lacks IEC 61000-4-5 surge rating above 1 A | Prefer for compact 12 V body control modules where 5 Mbps CAN-FD timing margin is critical |
Compared with NUP2114 and ESD224-BI, PESD2CANFD36UT-QR uniquely supports 24 V board nets with 36 V VRWM, maintains 4.3 pF capacitance for CAN-FD timing compliance, and delivers 1.5 A surge current handling - making it the only option qualified for heavy-duty truck CAN-FD gateways requiring simultaneous ESD and surge immunity.

FAQ
What is the maximum operating temperature for PESD2CANFD36UT-QR?
The device is qualified for junction temperatures up to +150 °C per AEC-Q101, with storage temperature range from -65 °C to +150 °C. Ambient operating range is -55 °C to +150 °C, validated via 1000-cycle thermal cycling and high-temperature reverse bias testing.
Can PESD2CANFD36UT-QR be used for single-line protection?
Yes - pin 1 and pin 3 form one ESD protection path (K1→CC), and pin 2 and pin 3 form another (K2→CC). Either path may be used independently, though both share the same cathode terminal (pin 3), requiring common grounding to system reference.
Is the 4.3 pF capacitance measured differentially or line-to-ground?
The 4.3 pF value is measured line-to-ground: Cd = 4.3 pF between pin 1 and pin 3, and identically between pin 2 and pin 3, at 1 MHz and VR = 2.5 V. Capacitance matching (ΔCd/Cd ≤ 0.5%) ensures balanced differential signal integrity.
Does PESD2CANFD36UT-QR support bidirectional signal lines like CAN-H and CAN-L?
Yes - its common-cathode dual-diode structure provides symmetrical clamping for both polarities on each line. When used on CAN differential pairs, it protects both CANH and CANL against ±15 kV ESD strikes without distorting the 1–2 V differential swing.
