A Transzorb (TVS) diode or ceramic capacitor is often added after the PTC to provide surge voltage suppression (>24V spikes) while the F4901 handles overcurrent. 4. How It Works (Circuit Behavior)
While the F4901 handles the overcurrent protection, the surrounding components in the schematic ensure the longevity of the entire system. Transient Voltage Suppressor (TVS Diode) f4901 1.1a 24v schematic
Safeguarding accessory power outlets.
If you are dealing with a dead board where the 24V rail has collapsed, the F4901 sub-circuit is a primary suspect. Use the following steps to diagnose the system: 1. Visual Inspection under Magnification A Transzorb (TVS) diode or ceramic capacitor is
