# PESD1CAN (Component) ## Description 6A 48V 26.7V Bidirectional 24V SOT-23 ESD and Surge Protection (TVS/ESD) ROHS The PESD1CAN is a bidirectional TVS (Transient Voltage Suppression) diode designed to protect automotive CAN bus communication lines from damage caused by ESD (electrostatic discharge), surge, and electrical fast transients. It uses silicon avalanche technology in a compact SOT-23 surface-mount package, allowing protection of two CAN signal lines with a single device. The diode is optimized for high-speed and fault-tolerant CAN networks commonly used in automotive and industrial systems. ESD protection up to ±30 kV (IEC 61000-4-2, air/contact) Peak pulse power: 200 W (8/20 µs waveform) Bidirectional protection for CAN_H and CAN_L lines Low clamping voltage for better signal protection Ultra-low leakage current (<1 µA typical) Low junction capacitance (~12–15 pF) for high-speed CAN signals Matched diode capacitance (very low mismatch ~0.1%) for signal integrity Small SOT-23 package (3-pin SMD) Complies with IEC 61000-4-2, -4-4, and -4-5 surge standards #CommonPartsLibrary #Diode ## Component Details - **Owner:** lcsc - **Created:** 11/3/2024 - **Last Updated:** 6/1/2026 - **Visibility:** Public - **Manufacturer Part Number:** PESD1CAN - **Package or Case Code:** SOT-23-3_L2.9-W1.3-P1.90-LS2.4-BL-2 - **LCSC Part Number:** C2687121 - **Forward Voltage:** 0.9V - **Manufacturer Name:** UMW(友台半导体) - **License:** https://creativecommons.org/licenses/by/4.0/ - **Datasheet URL:** https://www.lcsc.com/datasheet/C2687121.pdf?spm=wm.sxq.inf.ggs&lcsc_vid=T1kIXgFeT1NaU1RXQFBbUlUHT1cKU1NXFVBeX1VSTlAxVlNeR1JcUVZWQ1dZXjsOAxUeFF5JWBYZEEoKFBINSQcJGk4dAgUUFAk%3D - **Diode Type:** TVS Diode - **JLCPCB Part Class:** Extended Part - **Reverse Voltage:** 5V - **Part Type:** ESD Protection Devices - **Used in:** 218 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
