SMBJ5.0A

The SMBJ5.0A is a type of transient voltage suppressor (TVS) diode manufactured by FTR (Fujitsu Component Limited). It is designed to protect sensitive electronic components from voltage spikes and transients, which can occur due to various factors such as electrostatic discharge (ESD), lightning strikes, or power surges.

Key Features:

1. Voltage Rating: The SMBJ5.0A is rated for a breakdown voltage of approximately 5.0 volts. This makes it suitable for protecting circuits that operate at low voltage levels, ensuring that any transient voltage above this threshold is clamped to a safe level.

2. Power Dissipation: The device can handle a peak power dissipation of around 600 watts for a very short duration (typically 8/20 µs pulse). This capability allows it to absorb significant energy from transient events without failing.

3. Package Type: The SMBJ5.0A is housed in a DO-214AA (SMB) package, which is a surface-mount device (SMD) configuration. This package is compact and designed for efficient thermal management, making it suitable for modern electronic applications where space is at a premium.

4. Clamping Voltage: The clamping voltage is the maximum voltage that the device will allow to pass through during a transient event. For the SMBJ5.0A, this is typically around 8.0 volts, providing a safe margin above the breakdown voltage to protect downstream components.

5. Capacitance: The device has a low capacitance value, which is crucial for high-speed applications. This ensures that the TVS diode does not significantly affect the signal integrity of the circuit it is protecting.

6. Temperature Range: The SMBJ5.0A operates effectively over a wide temperature range, typically from -55°C to +150°C, making it suitable for various environmental conditions.

7. Applications: This TVS diode is commonly used in consumer electronics, telecommunications, automotive electronics, and industrial equipment. It is particularly useful in protecting data lines, power lines, and sensitive microcontroller inputs.

8. Compliance and Standards: The SMBJ5.0A complies with various industry standards for reliability and performance, ensuring that it meets the needs of modern electronic designs.

Summary:

The SMBJ5.0A from FTR is a robust and reliable transient voltage suppressor diode that provides essential protection for low-voltage electronic circuits. Its combination of low breakdown voltage, high power handling capability, and compact packaging makes it an ideal choice for a wide range of applications where transient voltage protection is critical.
