Dielectric strength

A distinction should be made between:

• Dielectric strength (destruction limit): Exceedance can result in irreversible changes to the electronics
• Against a specified reference ground
• Differential
• Recommended operating voltage range: If the range is exceeded, it can no longer be assumed that the system operates as specified
• Against a specified reference ground
• Differential

The device documentation may contain particular specifications and timings, taking into account:

• Self-heating
• Rated voltage
• Insulating strength
• Edge steepness of the applied voltage or holding periods
• Normative environment (e.g. PELV)
