TPD2E001-Q1

The TPD2E001-Q1 is a high-reliability transient voltage suppressor (TVS) diode array designed for automotive applications, manufactured by Texas Instruments. It features a dual-channel configuration with bidirectional protection, offering robust ESD (electrostatic discharge) and surge immunity up to ±8 kV per IEC 61000-4-2 standards. The device operates with a low clamping voltage of 5.5 V at 1 A, ensuring minimal stress on protected circuits during transient events. Its ultra-low leakage current of 1 μA at 25°C enhances system efficiency and reliability, particularly in power-sensitive environments. This component is qualified to AEC-Q101, making it suitable for harsh automotive conditions including wide temperature ranges from -40°C to +150°C. It provides excellent electrical performance under continuous operation, with a peak pulse current capability of 30 A (10/1000 μs), ideal for handling real-world electrical disturbances such as load dump or inductive kickback. The compact 2-pin SOT-23 package ensures easy integration into space-constrained designs without compromising thermal performance. The TPD2E001-Q1 is primarily used to protect sensitive interfaces like CAN bus lines, USB ports, and other communication lines in automotive electronics. It effectively safeguards microcontrollers, sensors, and control units from electrostatic discharge, electromagnetic interference (EMI), and voltage spikes originating from the vehicle’s electrical system or external sources. Its integrated protection reduces the need for additional components, simplifying board layout and lowering overall system cost. Designed for high-speed signal integrity, the device maintains low capacitance of 3 pF per channel, minimizing signal distortion in high-frequency applications. This makes it especially effective in modern vehicle systems that rely on fast data transmission, such as advanced driver-assistance systems (ADAS) and infotainment modules. The TVS array also supports fail-safe operation, ensuring continued functionality even after exposure to multiple transient events, which is critical for safety-related automotive functions. Texas Instruments’ commitment to quality and durability is evident in the TPD2E001-Q1’s design, which includes enhanced manufacturing processes and rigorous testing protocols. It meets stringent automotive industry requirements for reliability, consistency, and long-term performance, enabling engineers to build robust, compliant systems for next-generation vehicles.
