Automotive load dump resistor
Cost down solution of ISO7637-2 / ISO16750-2 pulse 5a/5b
In automotive systems, electronics must pass the ISO7637 EMC transient test(Pulse 5a/5b) to verify that the automotive electronics will not suffer from spikes and malfunction. In response to the surge immunity required by ISO7637 pulse 5a, a TVS function higher than pulse 5b must be selected to pass the test.
FIRSTOHM is providing the best solution for passing pulse 5a test. It is recommended to use an anti-surge resistor to reduce the impact of the surge on the circuit, as follows:
FIRSTOHM recommend alternative to ISO16750 for 12V battery system
FIRSTOHM recommend alternative to ISO16750 for 24V battery system
