SMBJ5349B-TP

The SMBJ5349B-TP is a transient voltage suppressor (TVS) diode manufactured by Micro Commercial Components (MCC). It is designed to protect sensitive electronic components from voltage spikes and transients, which can occur due to various factors such as lightning strikes, electrostatic discharge (ESD), or switching surges.

Key Features:

1. Type and Configuration: The SMBJ5349B-TP is a unidirectional TVS diode, meaning it is designed to conduct current in one direction and clamp voltage spikes to a safe level, protecting downstream components.

2. Peak Power Rating: This device has a peak power rating of 600 watts, which allows it to absorb significant energy from transient events without failing.

3. Reverse Stand-Off Voltage (V_RWM): The reverse stand-off voltage for the SMBJ5349B-TP is 49 volts. This is the maximum voltage that can be applied to the diode without causing it to conduct.

4. Clamping Voltage (V_C): When a transient event occurs, the clamping voltage is the maximum voltage that the diode will allow to pass through. For the SMBJ5349B-TP, the clamping voltage is typically around 76.5 volts at a specified peak pulse current.

5. Peak Pulse Current (I_PP): The device can handle a peak pulse current of 10A, which is crucial for protecting circuits from high-energy transients.

6. Package Type: The SMBJ5349B-TP is housed in a surface-mount package, specifically the SMB (DO-214AA) package, which is compact and suitable for automated assembly processes.

7. Operating Temperature Range: The diode operates effectively within a temperature range of -55°C to +150°C, making it suitable for a variety of environments and applications.

8. Applications: This TVS diode is commonly used in applications such as telecommunications, automotive electronics, consumer electronics, and industrial equipment, where protection from voltage transients is critical.

9. Compliance and Standards: The SMBJ5349B-TP is compliant with various industry standards, ensuring reliability and performance in critical applications.

Summary:

The SMBJ5349B-TP from Micro Commercial Components is a robust transient voltage suppressor designed to protect electronic circuits from damaging voltage spikes.
