Automotive-grade ESD for CAN transceivers VISUAL ZONE ESDCAN automotive-grade solution simplifies qualification and speeds time-to-market CAN interfaces need dualchannel, bidirectionnal, 24 V protection devices. After a first generation housed in SOT23-3L, STMicroelectronics has developped a family extension packaged in SOT323-3L. The new family range provides improvements with regards to dimensions (40% smaller), line capacitance (3.5 pF vs 30 pF) and voltage range. Indeed, the new serie includes also 37 V (VBR) products compatible with 24 V systems. ESDCANxxY series is working up to 175 ºC and sustains up to 30 kV ISO 10605 as well as ISO 7637 surges. KEY FEATURES KEY BENEFITS • Dual-line ESD and EOS protection • Robust and safe circuit at first design loop: • Bidirectional devices • CAN transceiver protected against ESD • Max pulse power: up to 250 W (8/20 μs) • Stand-off voltage: from 24 V up to 36 V • Low clamping factor VCL/VBR (VCL < 40 V) • Low leakage current: 100 nA max • Compliant with: • ISO 7637 3a and 3b • ISO 10605/IEC 61000-4-2: >25 kV air and contact and EOS • Enables high-density PCB thanks to the small package (SOT23-3L and SOT323-3L) • Transparency in the application lowering the design effort with • Capacitance compliant with CAN datarate www.st.com ELECTRICAL PARAMETERS (AT TAMB = 25 °C) IRM VRM VBR IPP (8/20) ISO 10605 (R=330 W, C=330pF) (µA) (V) min.
