SMF20VTR Frequently Asked Questions (FAQs)
-
ROHM recommends a compact PCB layout with short traces and minimal vias to reduce parasitic inductance and capacitance. A 4-layer PCB with a solid ground plane is recommended. Additionally, place the TVS diode close to the input pins and use a common ground point for the TVS diode and the protected circuit.
-
To select the correct TVS diode, consider the maximum voltage and current requirements of your application. Choose a TVS diode with a standoff voltage (VWM) that is higher than the maximum operating voltage and a peak pulse current (IPP) that is higher than the expected surge current. Also, consider the clamping voltage (VC) and the response time (tr) to ensure the TVS diode can respond quickly enough to protect your circuit.
-
Yes, you can use multiple SMF20VTR devices in parallel to increase the surge current rating. However, ensure that the devices are identical and have the same characteristics. Also, be aware that the clamping voltage may increase slightly due to the parallel connection. Consult ROHM's application notes for more information on parallel connection of TVS diodes.
-
The SMF20VTR is designed to provide ESD protection in addition to surge protection. It meets the IEC 61000-4-2 standard for ESD protection, which specifies a minimum of 8kV contact discharge and 15kV air discharge. The TVS diode's fast response time and low clamping voltage ensure that the protected circuit is not damaged by ESD events.
-
The SMF20VTR has an operating temperature range of -40°C to 150°C. However, the device's performance may degrade at extreme temperatures. Consult ROHM's datasheet and application notes for more information on temperature-related performance characteristics.
