MAX3208EEUB+ is the latest product of Texas Instruments for transient voltage suppression (TVS) diodes. It is designed and built with advanced micro-v structures to help protect electronic systems from voltage transients. It is a low-power, single-diode TVS device with a capacitance range of 0.35pF to 45pF.

Application

MAX3208EEUB+ is designed to be used in circuits where timed pulses, such as those from a digital circuit, need to be snubbed or dampened. The device can be used in conjunction with ferrite beads or other noise-suppressing components to help minimize RFI and EMI. It also helps reduce ringing and overall EMI noise in the system. It is an ideal choice for PCB protection and transient protection in boost converters, LED lighting, or PoE equipment.

Working Principle

The MAX3208EEUB+ is an ultra-low capacitance single-diode TVS. The device can clamp up to a rated voltage of 18V and a peak pulse current of 6A. Internally, the device utilizes an avalanche breakdown mechanism to ensure clamping occurs quickly and efficiently. To ensure the device’s low capacitance characteristics, a zener structure is employed internally that restricts the flow of current and allows for a short-length of time when maximum current is applied through the device. This design ensures that the device maintains its low capacitance values, resulting in fast clamping times and low leakage currents.

The device also offers several features that make it even more efficient. These include a low clamping voltage, fast acting turn-on time, and a high breakdown voltage. As such, the device is able to accurately clamp and dissipate hazardous peak transients, ensuring that your system remains protected even from the most severe voltage transients.

Conclusion

The MAX3208EEUB+ is the latest addition to the Texas Instruments’ line of transient voltage suppression diodes. It is an ultra-low capacitance single diode device with a rated voltage of 18V and a peak pulse current of 6A. It is designed to help protect electronic systems from voltage transients, and it can be used with other noise-suppressing components to reduce RFI and EMI. The device is designed to have a low clamping voltage, fast acting turn on time, and a high breakdown voltage; all these features make it an ideal choice for protection against transient voltage surges.
