Overview
Description
Key features of the SMBJ170A include:
1. Peak Pulse Power: It typically offers a peak pulse power dissipation of 600 watts for a 10/1000 µs waveform, as per the industry-standard testing method.
2. Voltage Rating: The "170A" in its name indicates a working standoff voltage of 170 volts, making it suitable for circuits operating at or below this voltage.
3. Design: It is housed in a DO-214AA (SMB) package, which allows for easy integration into circuit boards, especially useful in compact or space-constrained applications.
4. Unidirectional: The ‘A’ suffix denotes a unidirectional configuration, which is designed to handle voltage in one direction, providing effective protection for DC-powered equipment.
Overall, the SMBJ170A is ideal for safeguarding devices from potential damage due to overvoltage conditions.

Features
1. Reverse Stand-Off Voltage: 170V, indicating the maximum voltage it can withstand without conducting in reverse.
2. Power Dissipation: Capable of dissipating up to 600W of power, providing robust protection against voltage spikes.
3. Response Time: Fast response time, typically in the picoseconds range, ensuring quick protection against transient events.
4. Package Type: Available in an SMB (DO-214AA) package, which is a surface-mount design, allowing for easy integration into circuit boards.
5. Polarity: Unidirectional, designed to conduct in one direction only, making it suitable for circuits with a specified current flow direction.
6. Clamping Voltage: Low clamping voltage, ensuring minimal voltage overshoot during transients.
7. Operating Temperature: Wide operating temperature range, enhancing its reliability under varying environmental conditions.
8. Compliance: Meets industry standards for surge protection, making it suitable for various applications in consumer electronics, automotive, and industrial sectors.
Pinout
The pin count for the SMBJ170A is 2. These are the anode and cathode pins. It functions by clamping voltage spikes to a safe level, thereby protecting circuit components from damage due to overvoltage transients. The "170A" in the part number indicates a breakdown voltage of 170 volts with an "A" type indicating it is unidirectional.
TVS diodes like the SMBJ170A are commonly used in applications where voltage transients are likely to occur, such as in power supply circuits, communication lines, and automotive applications.
