Damping Voltage Peaks: Protection for Sensitive Components
The Low Resistance RC Snubber Shunt
ISABELLENHÜTTE has developed a powerful low-resistance snubber shunt, SMT-V, which has a particularly high pulse load capacity. During fast switching processes in power electronics, e.g. in the automotive sector, voltage peaks can cause inductances that can damage or destroy downstream sensitive components in the circuit. To dampen these voltage peaks, a so-called RC snubber shunt can be used to dissipate the excess energy to the outside.
All About Pulses
The SMT-V is capable of absorbing a pulse energy of 2.5J with a pulse duration of 0.1s at a contact point temperature of 120°C and a number of 50 pulses over a lifetime with a corresponding gap time. This corresponds to a power loss per pulse of 25W.
Figure 1 shows an illustration of a snubber posture. The SMT-V has an ohmic resistance of 17.5mOhm and size 2512. Samples can be ordered now.
