SMAJ36CA

The SMAJ36CA is a specific type of transient voltage suppressor (TVS) diode manufactured by FTR (Fujitsu). This component is designed to protect sensitive electronic circuits from voltage spikes and transients, which can occur due to various factors such as lightning strikes, electrostatic discharge (ESD), or switching events in power circuits.

Key Features and Specifications:

1. Type: The SMAJ36CA is a unidirectional TVS diode, meaning it is designed to clamp voltage in one direction, providing protection for circuits that require a specific polarity.

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

3. Reverse Stand-Off Voltage (V_RWM): The device has a reverse stand-off voltage of 36 volts, which is the maximum voltage that can be applied to the diode without causing it to conduct. This makes it suitable for applications where the normal operating voltage is below this threshold.

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 SMAJ36CA, this is typically around 55 volts, ensuring that connected components are protected from excessive voltage.

5. Capacitance: The diode has a low capacitance value, which is beneficial for high-speed data lines, as it minimizes signal distortion and maintains signal integrity.

6. Package Type: The SMAJ36CA is housed in a DO-214AA (SMA) package, which is a surface-mount device (SMD) that allows for easy integration into printed circuit boards (PCBs). The compact size of the package makes it suitable for space-constrained applications.

7. Operating Temperature Range: The device can operate over a wide temperature range, typically from -55°C to +150°C, making it suitable for various environmental conditions.

8. Applications: The SMAJ36CA is commonly used in automotive electronics, telecommunications, consumer electronics, and industrial equipment, where protection from voltage transients is critical.

9. Compliance and Standards: The device often meets various industry standards for reliability and performance, ensuring it can be used in demanding applications.

Summary:

In summary, the SMAJ36CA from FTR is a robust and reliable transient voltage suppressor diode designed to protect electronic circuits from harmful voltage spikes. With its high power rating, low clamping voltage, and compact package, it is an ideal choice for a wide range of applications requiring transient protection.
