PESD2CANFD24L-TR

PESD2CANFD24L-TR is a two-channel ESD protection diode array designed for CAN and CAN FD interfaces. It protects CAN_H and CAN_L lines from electrostatic discharges and transient surges while preserving signal integrity on automotive/industrial networks. Key features typically include very low per-channel capacitance to minimize bus distortion, bidirectional clamping to protect the transceiver, and a working voltage suitable for CAN bus voltages (up to about 24 V). The “TR” suffix denotes Tape-and-Reel packaging for automated assembly. Typical use: protecting CAN transceivers at the physical layer entry points. For exact electrical specs, clamping voltages, capacitance, and ESD levels, consult the datasheet.

Equivalent products are other two‑channel CAN/CAN-FD ESD protection diode arrays with similar 24 V working voltage. Examples from major vendors include: TI TPD2CANFD (CAN/CAN-FD ESD protection), Onsemi NUP-series multi-line ESD protectors suitable for CAN, Littelfuse SP305x family CAN bus ESD arrays, and STMicroelectronics CAN-bus ESD protection devices. For exact cross‑reference, provide package (SOT-23-6, SO-8, etc.) and voltage, and I’ll give precise part numbers.

Key features of PESD2CANFD24L-TR:
- 2-channel ESD protection for CAN bus lines (CAN_H and CAN_L)
- CAN and CAN FD compatible; rated for 24 V line protection
- Very low input capacitance per channel (~1 pF typical) to minimize signal distortion
- Bidirectional protection with clamps to VCC/GND; fast response to ESD events
- Wide operating temperature: -40°C to 125°C
- Passive device (no power supply required)
- Small 6-pin package, Tape & Reel (TR), RoHS-compliant, lead-free

- Pin count: 3 pins (CANH, CANL, GND).
- Function: ESD protection diode array for CAN/CAN FD bus. It clamps surges on CANH and CANL to ground, providing transient protection before the CAN transceiver. The TR suffix indicates Tape & Reel packaging.
