TVS (transient voltage suppression) diodes, Varistors, and MOVs (metal oxide varistors) are important components for transient voltage suppression that are used in a wide range of modern electronic devices. The ROV14-220L-S is a popular part produced by TE Connectivity (formerly Tyco Electronics) that offers superior performance in transient suppression. This article will discuss the application field and working principle of the ROV14-220L-S.

The ROV14-220L-S is mainly used for high frequency line transient voltage suppression. It has a voltage Clamping Level of 14 volts and a Peak Pulse current of 1.1, 145 amps. It can suppress voltage sudden increases that are caused by ESD (electrostatic discharge) and EFT (electrical fast transient). It also has a wide frequency range of 100MHz to 300MHz. It is a Type 2 surge protection component, which means it is suitable for applications that require heavier protection against voltage spikes.

The ROV14-220L-S is thee encapsulated in a UL 94V-0 UL 94V-0 plastic case with epoxy resin to protect it from external environmental factors. It also features solderability test in 280°C for one second, moisture resistance and thermal shock capability. Furthermore, it is UL approved and RoHS compliant, which makes it suitable for use in most applications.

The ROV14-220L-S is comprised of a proprietary mechanical PIN varistor sandwiched between 2 diodes. It has a diode forward bias voltage of 0.6V to 1.3V and a Varistor clamping voltage of 12V to 14V. The PIN Varistor acts as a variable resistor that is activated when a certain voltage is applied. When this voltage is exceeded, it switches from a high resistance state to a low resistance state, allowing the current to flow through the resistor and absorb the excess energy. By doing so, any voltage spikes that exceed the normal operating voltage are suppressed.

In conclusion, the ROV14-220L-S is a valuable transient voltage suppression component, offering excellent protection against voltage spikes and transient surges. Its encapsulation, wide frequency range, and UL approval make it an ideal choice for high frequency line transient voltage suppression applications. Thanks to its wide range of features, the ROVE-220L-S has become one of the most popular products of its kind currently available.
