PESD2CANFD24VT-QR

PESD2CANFD24VT-QR is a two-channel ESD protection diode array designed for CAN and CAN-FD networks. It protects CAN_H and CAN_L from electrostatic discharges and transients in automotive and industrial environments. The “24V” in the name indicates compatibility with higher automotive CAN bus voltages, delivering bidirectional protection with low input capacitance to preserve CAN-FD signaling, fast response, and low leakage. The VT-QR packing denotes tape-and-reel with QR code for automated assembly and traceability.
Typical applications: ECUs, gateways, instrument clusters, and industrial controllers using CAN/CAN-FD.
Note: For exact electrical specifications (ESD ratings, capacitance, leakage, clamp voltages, max continuous voltage) and pinout, consult the official datasheet from the manufacturer.

Equivalent products are dual-line TVS/ESD diodes specified for CAN‑FD with ~24 V standoff. Vendor families to consider: Semtech RClamp series, STMicroelectronics CAN‑FD TVS diodes, Vishay CAN‑FD TVS (SM15/SMBJ variants), ON Semiconductor TVS/ESD parts, Rohm CAN‑FD protection devices. Always match standoff voltage, breakdown/clamp voltage, capacitance, surge/ESD ratings and package before substituting.

PESD2CANFD24VT-QR features:
- 2-channel ESD protection for CAN High and CAN Low lines (CAN/CAN-FD)
- 24V bus tolerance (stand-off voltage up to 24V)
- Ultra-low capacitance per channel (≈0.8–1.2 pF) to minimize signal distortion
- Low leakage with fast clamping for ESD/transient events
- Bidirectional protection suitable for CAN transceiver interfaces
- Automotive-ready with wide operating temperature range
- Small package, Tape & Reel with QR suffix for automated assembly
- RoHS compliant (lead-free)
Note: exact electrical figures and compliance levels are in the datasheet.

Pin count: 3 pins (two protected signal pins + common reference/ground).
Function: Dual-line TVS/ESD protector specifically for CAN FD buses. It clamps transients (ESD, surge) on the two CAN wires to the common reference, providing IEC 61000‑4‑2 level ESD protection, low capacitance for high‑speed signaling, and a ~24 V working/standoff level. The -T/-QR suffix denotes packaging (tape & reel).

Manufacturer: Nexperia B.V.
What kind of company: Nexperia is a global semiconductor manufacturer (headquartered in the Netherlands) that designs and produces discrete semiconductor components, MOSFETs, logic ICs and analog/protection devices (including ESD/TVS parts) for automotive, industrial and consumer electronics markets.

Applications: ESD and transient protection for CAN and CAN FD interfaces in 24V automotive and industrial networks. Suitable for ECUs and gateways in vehicles (powertrain, body/chassis, ABS, airbags, ADAS) and for 24V industrial equipment (PLCs, motor drives, robotics, distributed I/O) that use CAN or CAN FD. Provides two-channel protection for CAN_H and CAN_L with low input capacitance to preserve CAN FD signaling, in a compact QR tape-and-reel package for automated assembly.

PESD2CANFD24VT-QR uses a 6-pin SC-70/SOT-23-6 package (RoHS, tape & reel).
