SMAJ170CA-13-F

The SMAJ170CA-13-F is a specific type of transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated. This component is designed to protect sensitive electronic devices from voltage spikes and transients, which can occur due to various factors such as lightning strikes, electrostatic discharge (ESD), or inductive load switching.

Key Features:

1. Voltage Rating: The SMAJ170CA-13-F has a breakdown voltage of approximately 170 volts, making it suitable for applications that require protection against high-voltage transients.

2. Power Dissipation: This diode can handle a peak power dissipation of around 400 watts, which allows it to absorb significant energy during transient events without failing.

3. Package Type: The diode is housed in a surface-mount SMA (DO-214AC) package, which is compact and suitable for automated assembly processes. The package dimensions typically measure about 5.2 mm in length and 3.5 mm in width, with a height of approximately 1.5 mm.

4. Clamping Voltage: The clamping voltage of the SMAJ170CA-13-F is relatively low, ensuring that the voltage across the protected load remains within safe limits during a transient event.

5. Response Time: The diode features a fast response time, which is critical for effectively clamping voltage spikes and protecting sensitive components.

6. Operating Temperature: The device is rated for a wide operating temperature range, typically from -55°C to +150°C, making it suitable for various environmental conditions.

7. Applications: The SMAJ170CA-13-F is commonly used in automotive electronics, telecommunications, consumer electronics, and industrial applications where overvoltage protection is essential.

8. RoHS Compliance: The component is compliant with the Restriction of Hazardous Substances (RoHS) directive, ensuring that it is free from certain hazardous materials, making it environmentally friendly.

Electrical Characteristics:

• Reverse Stand-off Voltage (V_R): 170V
• Breakdown Voltage (V_BR): Typically around 188V
• Clamping Voltage (V_C): Approximately 250V at a specified peak pulse current
• Peak Pulse Power (P_PP): 400W (for a 10/1000μs waveform)

Conclusion:

The SMAJ170CA-13-F from Diodes Incorporated is a robust and reliable transient voltage suppressor diode that provides essential protection for electronic circuits against voltage transients. Its high breakdown voltage, fast response time, and compact package make it an ideal choice for a wide range of applications where overvoltage protection is critical.
