Defibrillator pulses deliver massive energy to a patient. If the internal defibrillation protection circuits (gas discharge tubes, transient voltage suppression diodes) fail, the downstream semiconductor amplifiers will destroy themselves.

Elias plugged the machine in. He didn't turn it on immediately. He checked his wiring three times against the fixed diagram. Everything matched. Defibrillator pulses deliver massive energy to a patient
Use a multimeter in "diode mode" to check for shorts. If a diode shows 0.00V in both directions, it is blown and must be replaced with an identical rating to maintain safety standards. B. Operational Amplifier (Op-Amp) Drift

: Use a desoldering iron, pump, or wick to carefully remove the old semiconductor. Note the orientation (polarity) before removal. Installation
Always replace semiconductors with the exact part numbers specified in the manufacturer's service manual PDF. If an exact replacement is obsolete, cross-reference the specifications (slew rate, noise density, common-mode rejection ratio) using reputable semiconductor distributor databases to find an approved equivalent.
