SMCJ13A-TR Transient Voltage Suppressor by STMicroelectronics

The SMCJ13A-TR from STMicroelectronics is a robust transient voltage suppressor (TVS) designed to protect sensitive electronic equipment from voltage transients induced by system-induced surge events and other transient voltage spikes. This device is particularly well-suited for the protection of voltage-sensitive components that are commonly found in industrial, telecommunications, and consumer electronics applications.

Key Features

• Stand-off Voltage: The SMCJ13A-TR has a stand-off voltage of 13V, making it suitable for a range of applications where this voltage level is critical for proper operation.
• Peak Pulse Power: It offers a peak pulse power dissipation of 1500 Watts (at 10/1000μs waveform), ensuring robust protection against high energy transients.
• Breakdown Voltage: The minimum breakdown voltage is 14.4V, which provides a margin above the stand-off voltage to prevent leakage currents during normal operation.
• Clamping Voltage: With a maximum clamping voltage of 21.5V (@ IPP), the device ensures that the voltage seen by the protected component does not exceed a safe level during transient conditions.
• Low Leakage Current: The SMCJ13A-TR is characterized by its low leakage current, enhancing system reliability and reducing power consumption when the device is in standby mode.
• Fast Response Time: The TVS diode provides a fast response time to transient events, typically in the order of picoseconds, ensuring immediate protection for the circuit components.
• Package: Supplied in a DO-214AB (SMC) package, the SMCJ13A-TR offers a compact footprint and is suitable for high-density circuit board designs.
• Compliance: This device meets the ISO 7637-2 pulse 3a and 3b requirements and is compliant with IEC 61000-4-2 and IEC 61000-4-4 standards, providing confidence in its ability to withstand environmental and electrical stresses.
