ESD2CAN24DBZRQ1 Descripción general
A TVS diode, also called a transient-voltage suppressor, is a protection component that diverts short high-voltage pulses away from sensitive circuitry. Automotive CAN links are particularly vulnerable because external wiring can receive electrostatic discharge and transient events. The ESD2CAN24-Q1 family is positioned at the interface boundary, helping protect the connected transceiver without materially loading the data line.
The device provides two protected channels in a compact SOT-23 package. Its typical capacitance is 3 pF, helping preserve the high-speed edge behavior expected by automotive digital interfaces. The protection rating is specified as ±30 kV ESD, while the verified product information also identifies an ISO 10605 capability of ±27 kV contact and ±27 kV air-gap discharge. Its bidirectional structure supports protection against either transient polarity on the protected lines.
The ESD2CAN24DBZRQ1 is identified as an automotive TVS and is associated with AEC-Q101 qualification in the verified product and cross-reference information. The operating temperature range reported by the verified source is −55 °C to +150 °C. The DBZ package is intended for surface-mount assembly, and the RQ1 ordering suffix identifies the automotive-qualified product variant. A typical clamp condition is 37 V, with 5.7 A peak pulse current for an 8/20 microsecond pulse.
Use this device on CAN transceiver inputs or other automotive network connections after confirming signal polarity, line impedance, trace geometry, and the protection current path. Its 3 pF capacitance is suitable for low-capacitance protection, but PCB placement and grounding remain important for effective transient diversion. The protector should be placed close to the connector or entry point, with short, low-inductance connections to the protected circuitry.
This page combines verified manufacturer and distributor information with practical protection guidance, comparison information, and application-oriented design notes. It is intended to help engineers identify the correct automotive ESD-protection footprint, verify ratings, and plan PCB implementation without assuming parameters that are not present in the supplied data.

Aplicaciones típicas
ESD2CAN24DBZRQ1 es adecuado para 6 aplicacións: Automotive CAN Transceiver Protection, In-Vehicle Network Body Modules, Automotive Infotainment Interfaces, Vehicle Diagnostic Connectors, Automotive Gateway and Communication Hubs, Automotive Telematics Units.
Automotive CAN Transceiver Protection
ESD2CAN24DBZRQ1 fits directly at an automotive CAN interface boundary where both CAN conductors must be protected from electrostatic discharge. Its dual bidirectional structure is intended for CAN H and CAN L protection, while the typical 3 pF capacitance helps preserve high-speed transitions through the protected transceiver. The verified ±30 kV ESD rating and ISO 10605 references make it suitable for transient-protection evaluation on in-vehicle networks. Place the SOT-23 device close to the connector or transceiver entry point, route transient current through a short low-inductance path, and verify the exact DBZ pin mapping before layout release.

In-Vehicle Network Body Modules
Body-control and gateway modules often expose several wired vehicle-network connections to ESD through connector harnesses. ESD2CAN24DBZRQ1 provides two protected channels in a compact SOT-23 footprint, allowing designers to add local protection without changing the logical network topology. The 3 pF typical capacitance is useful when preserving signal integrity matters, while the −55 °C to +150 °C operating range supports automotive temperature environments. Confirm the module’s connector pinout, reference-ground arrangement, and required transient test levels, then place the protector ahead of sensitive CAN transceiver pins to minimize unprotected trace length.
Recomendado
Automotive Infotainment Interfaces
Infotainment head units can connect CAN networks to internal control logic while exposing those networks to user-accessible wiring and chassis-related ESD events. ESD2CAN24DBZRQ1 can be evaluated as a compact two-line suppressor at the connector or transceiver boundary. Its low typical capacitance of 3 pF helps avoid unnecessary loading of the data interface, and its bidirectional construction accommodates either transient polarity. Because infotainment systems can combine many external and internal conductors, engineers should verify the exact lines being protected, grounding strategy, cable length, and whether a separate higher-energy surge suppressor is required.
Recomendado
Vehicle Diagnostic Connectors
Diagnostic connectors are exposed to service technicians, test equipment, and vehicle wiring, making them practical locations for ESD-protection components. A dual-channel protector such as ESD2CAN24DBZRQ1 can be placed across the relevant CAN pair near the connector to reduce the amount of unprotected copper reaching the transceiver. The stated 37 V typical clamp voltage and 5.7 A peak pulse current at 8/20 microseconds provide the verified starting points for protection-circuit evaluation. Engineers should still check the connector’s signal levels, isolation topology, cable-routing assumptions, and the actual system ESD test conditions before finalizing the placement.
Recomendado
Automotive Gateway and Communication Hubs
A vehicle gateway may bridge multiple network domains and provide a centralized interface between CAN and other vehicle networks. ESD2CAN24DBZRQ1 is appropriate for local protection of a protected CAN pair when the gateway’s surge requirements match the family’s stated automotive ratings. The small SOT-23 package helps conserve board area in dense electronic control units, while the 3 pF typical capacitance limits added interface loading. Validate the protector against the gateway’s ground reference, connector geometry, isolation barriers, and production ESD test plan; if the line also experiences large inductive or overvoltage events, additional coordinated protection may be necessary.
Recomendado
Automotive Telematics Units
Telematics modules often combine a CAN connection with communication hardware and exposed vehicle wiring, creating a useful application for local ESD suppression. ESD2CAN24DBZRQ1 can protect the CAN conductors before they reach the transceiver, reducing transient stress on sensitive interface electronics. Its 3 pF typical capacitance helps maintain signal behavior, while the automotive temperature range of −55 °C to +150 °C covers demanding internal environments. Design review should include the cable harness assumptions, connector shield or return path, ground bounce behavior, and the distinction between ESD protection and larger transient-energy suppression.

Diferenciadores clave
- Verified automotive CAN protection positioning (frente a SM24CANA-02HTG)

- Low verified interface capacitance (frente a ESD2CANFD24DBZRQ1)
Notas de diseño
Place ESD2CAN24DBZRQ1 as close as practical to the connector or protected CAN transceiver pins. Keep the protected traces short and route the transient-current path directly through the device to the intended low-impedance return or ground reference. Long loops increase parasitic inductance and reduce the effectiveness of the clamp. Confirm the DBZ land pattern, pin numbering, and exposed or unused terminal treatment against the manufacturer datasheet before fabrication.
Do not treat ESD2CAN24DBZRQ1 as a universal surge protector. The verified values describe automotive ESD protection, including ±30 kV ESD and ISO 10605 references, while the supplied information does not establish a broader lightning, load-dump, or high-energy surge rating. If the cable can receive larger transient events, select a protection network that explicitly covers those conditions. Also do not substitute ESD2CAN24DCKRQ1 without redesigning the PCB because DCK is a different package.
Use the lowest practical connection inductance between the connector pins and the ESD2CAN24DBZRQ1 I/O pins. Avoid routing the protected signal through a long section of board copper before the suppressor, and keep the device’s return connection short and continuous. Validate the ground reference against the vehicle chassis or circuit-ground architecture used by the selected CAN transceiver. The component’s 3 pF typical capacitance is only one part of the complete signal-integrity budget; trace, connector, and transceiver parasitics must also be considered.
Información de cumplimiento
The verified product and cross-reference snippets identify the device as an automotive TVS and mention AEC-Q101 and RoHS/Green in third-party material, but no directly linked manufacturer compliance statement was supplied for every field. Values remain unknown where the supplied data does not explicitly establish them. The target is not classified as AEC-Q100 in this output because the verified automotive qualification reference is AEC-Q101.
