PESD2CANFD24LT-QR

PESD2CANFD24LT-QR is a two-channel ESD protection diode array designed for CAN and CAN-FD transceivers. It protects the CAN High and CAN Low lines from electrostatic discharge and surges while keeping signal integrity thanks to very low input capacitance and bidirectional protection. The device targets CAN/CAN-FD automotive nets with about a 24 V working/standoff voltage, suitable for 12/24 V systems, and clamps fast pulses per IEC 61000-4-2. The LT suffix indicates lead-free packaging; QR denotes tape-and-reel packaging for automated assembly. Typical uses include automotive ECUs, gateways, and body controllers that employ CAN or CAN-FD. Benefits: rugged ESD protection with minimal impact on signaling, compact footprint, easy integration with standard CAN transceivers. For exact electrical specs, pinout, and packaging details, consult the manufacturer’s datasheet.

PESD2CANFD24LT-QR features:
- 2-channel ESD protection for CAN and CAN-FD transceivers
- 24-V CAN bus working voltage (industrial/automotive CAN domain)
- Very low line capacitance per channel (typical ~2 pF) to preserve CAN signaling
- Ultra-low leakage current
- Fast ESD response with low clamp voltage to safeguard devices
- Wide operating temperature: -40°C to +125°C
- RoHS-compliant (Pb-free)
- Packaging: QR (Tape & Reel) for automated assembly
- Ideal for automotive/industrial CAN and CAN-FD interfaces

- Pin count: 3 pins (SOT‑23 style package: CAN_H, CAN_L, and GND).
- Function: Dual, bidirectional transient voltage suppression (ESD/surge) device that protects the two CAN‑FD bus lines (CAN_H and CAN_L) to ground. It provides low‑capacitance, high‑speed protection for CAN FD transceivers against ESD, EFT and transient overvoltage events while preserving signal integrity.
