6 Transient Protection
The TPS1HC30EVM provides several footprints and populated components used to mitigate transient power
events such as ESD, surges, and inductive load turn-offs. These protection mechanisms are provided in addition
to the integrated transient mitigation features of the TPS1HC30-Q1. Refer to the TPS1HC30-Q1 data sheet for
more information about the internal protections that the device provides.
The TPS1HC30EVM provides the following transient protection features:
• Input TVS diode on VS (D2) to protect against upstream power events (not populated)
• Optional external inductive load turn-off diode footprints on D3 to provide a mechanism to discharge an
inductive load if the internal clamp is not adequate (not populated)
