The SMAJ30CA-TR is a robust transient voltage suppression (TVS) diode designed by STMicroelectronics, a global semiconductor leader known for its commitment to delivering state-of-the-art electronic components. This TVS diode is specifically crafted to safeguard sensitive electronic equipment from voltage transients induced by system inductance or lightning strikes.

Key Features

• Stand-off Voltage: The device features a stand-off voltage of 30V, making it suitable for a wide range of applications where this voltage level is a common requirement.
• Bi-directional Protection: As a bi-directional diode, the SMAJ30CA-TR provides protection in both directions, ensuring the safety of the circuit regardless of the polarity of the transient.
• High Surge Capability: With its high surge capability, this TVS diode can handle significant transient spikes, effectively clamping and dissipating the energy to protect the downstream components.
• Low Clamping Voltage: It offers a low clamping voltage relative to its stand-off voltage, which ensures minimal voltage stress on the protected component during a transient event.
• Fast Response Time: The SMAJ30CA-TR reacts quickly to transient overvoltages, providing prompt protection and limiting the exposure of the circuit to potentially damaging spikes.
• Compact Package: Housed in the SMA (DO-214AC) package, this diode is compact and suitable for high-density circuit designs.
