TransGuards™ can be broken into three families – discrete devices, array devices, and feed-through filter configurations. The discrete devices offer the smallest foot print and highest in-rush current suppression while the array devices are ideal for parallel bus structures – interfaces, I/Os, differential circuitry, etc. Finally, TransFeed™ filters act like notch filters in the ON state and like back-to-back zeners in the OFF state. These devices are ideal in mixed signal environments, especially RF/Digital environments.
