SMCJ20A-TR Transient Voltage Suppressor by STMicroelectronics

The SMCJ20A-TR is a robust transient voltage suppressor (TVS) diode designed by STMicroelectronics to protect sensitive electronic equipment from voltage spikes and transients induced by lightning and other transient voltage events. This high-quality TVS diode is a preferred choice for safeguarding voltage-sensitive components in various applications, including industrial, computing, automotive, and consumer electronics.

Key Features

• Stand-off Voltage: The device offers a stand-off voltage of 20V, providing a stable protective barrier for circuits operating at or below this voltage level.
• Peak Pulse Power: With its impressive peak pulse power dissipation of 1500W (10/1000μs), the SMCJ20A-TR can effectively handle significant transient power spikes without compromising its integrity or the safety of the protected component.
• Clamping Voltage: Upon encountering a voltage surge, the clamping voltage of the device activates, rapidly limiting the excess voltage to a safe level, thereby preventing damage to the downstream circuitry.
• Fast Response Time: The SMCJ20A-TR boasts an exceptionally fast response time to transient events, ensuring that the sensitive components are shielded promptly.
• Low Leakage Current: With minimal leakage current in its standby state, the device ensures energy efficiency and does not impede the normal operation of the circuit.
• Package: The device comes in a low-profile SMC (DO-214AB) package, which is suitable for high-density board installations and is compatible with standard PCB assembly processes.
