The SMCJ26A-TR from STMicroelectronics is a robust Transient Voltage Suppressor (TVS) diode, designed to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events. This TVS diode is a popular choice for safeguarding voltage-sensitive components in a wide range of applications, including industrial, commercial, and consumer electronics.

Key Features

• Stand-off Voltage: The SMCJ26A-TR has a stand-off voltage of 26V, making it suitable for a variety of circuits that operate at similar voltage levels.
• Peak Pulse Power: It offers excellent clamping capability with a peak pulse power dissipation of 1500 Watts (10/1000μs waveform), ensuring protection against high energy transients.
• Clamping Voltage: With a maximum clamping voltage of 42.1V at 37.5A, this diode provides a high degree of protection, clamping transient overvoltages and preventing damage to the protected component.
• Low Leakage Current: The low leakage current of less than 1μA at 26V means that the diode will not significantly affect the normal operation of the circuit by drawing excess current when not in its clamping state.
• Fast Response Time: The device offers a fast response time, typically in the picosecond range, ensuring quick protection for sensitive circuits.
• Package: The SMCJ26A-TR is available in an SMC (DO-214AB) package, which is known for its compact size and reliability, making it suitable for high-density circuit designs.
