TVS - Diodes

TVS (Transient Voltage Suppression) Diodes are Silicon-based components designed to protect sensitive electronics against high voltage / high current surges. Unlike other types of Surge Suppression devices, such as MOVs (Metal Oxide Varistors), TVS Diodes are fast acting and provide a precise, high-quality response. They also have no “memory”, meaning they can be reset with no additional protection or maintenance.

The most common type of TVS Diode is the 1KSMB170A, which is designed to stabilize high voltage or current spikes. The 1KSMB170A is typically used in the design of circuit protection, whether they be AC or DC applications. In fact, the 1KSMB170A is used in almost any line of electronic products, including home and industrial electronics, telecom and medical equipment.

The 1KSMB170A Diode works by suppressing high energy spikes before they can reach the protected components. It is capable of dissipating surges of up to 170 Watts, with peak pulse power dissipation of 2 kilowatts. It also has an adjustable On/Off Threshold between 6VDC/14VDC and an open circuit voltage of 43 volts. The device can be installed in a variety of medical and industrial applications, including direct PCB mounting, as well as through-hole mounting.

Another key feature of the 1KSMB170A is its low capacitance, which makes it ideal for applications where high capacitive loading or ringing can wreak havoc on system reliability. This low capacitance also makes the 1KSMB170A an excellent choice for EMI/RFI (Electromagnetic Interference / Radio Frequency Interference) shielding, as it is capable of absorbing high level noise without loading the protected equipment.

In addition to its performance capabilities, the 1KSMB170A is highly reliable and features a temperature compliancy of -55 to + 125°C. It is also RoHS compliant and is UL and CSA certified, meaning it is safe and approved for consumer and industrial applications.

All in all, the 1KSMB170A is a reliable, fast-acting device that effectively protects sensitive electronics against high voltage / current surges. Its low capacitance and excellent surge rating make it an excellent choice for a wide variety of applications, and its affordability and universal compatibility make it one of the most reliable and widely used TVS Diodes on the market today.
