TVS – Varistors, MOVs encompasses a wide range of components and applications. Among them is the BSPM1A385D500LVR. This device is applied in motor control and car-ignition control circuits where protection against transient voltage spikes is critical. As a varistor, its working principle is that of a voltage-dependent resistor.

Essentially, the resistance value of a varistor decreases drastically when exposed to higher voltages. As a result, when a surge of voltage due to a transient voltage spike enters the circuit, the maximum voltage that the sensitive components of the circuit are exposed to is limited. Thus, the varistor offers protection against these strong surges.

The BSPM1A385D500LVR features a highly superior stability and reliability. Its peak pulse current capability is 1.3 KA, while its V-I function has a jump-to-failure voltage of 500 V. Its energy-resistant properties are also impressive, with the varistor being able to withstand an energy up to 12.5 Joules.

In terms of dimensions, the varistor has a diameter of 7.4 mm, a height of 4.1 mm and a lead length of 25 mm, which makes it suitable for integration into tight spaces. It also features a low thermal resistance of 4°C/W. Moreover, the device is a RoHs compliant, meaning that it is free of toxic components that could harm the environment.

While most varistors suffer a significant decrease in response time with respect to their initial break-down voltage values when exposed to over-voltage surges, the BSPM1A385D500LVR features a response time lower than 20 nanoseconds. Therefore, components in the circuit are able to be quickly protected from the surge.

In conclusion, the BSPM1A385D500LVR is a varistor suitable for protecting motor control and ignition control circuits against transient voltage spikes, due to its impressive energy-resistant properties, small dimensions and superior response time. Its peak pulse current capabilities and V-I function durability make it extremely reliable, and its RoHs compliance makes it ecologically friendly.
