NTSOA – Negative Transient Safe Operating Area
In a typical motor drive system, dV/dt is typically designed to be in the range of 3 – 5 V / ns. The negative VS
transient voltage can exceed this range during some events such as short circuit and over-current shutdown,
when di/dt is greater than in normal operation.
Infineon’s HVICs have been designed for the robustness required in many of today’s demanding applications. An
indication of the 2ED2110S06M’s robustness can be seen in Figure 19, where the 2ED2110S06M’s Safe Operating
Area is shown at VBS=15 V based on repetitive negative VS spikes. A negative VS transient voltage falling in the
grey area (outside SOA) may lead to IC permanent damage; vice versa unwanted functional anomalies or
permanent damage to the IC do not appear if negative Vs transients fall inside the SOA.

Negative VS transient SOA for 2ED2110S06M @ VBS=15 V
Even though the 2ED2110S06M has been shown able to handle these large negative VS transient conditions, it
is highly recommended that the circuit designer always limit the negative VS transients as much as possible by
careful PCB layout and component use.
