Instructions:

1. Mounting: Ensure the device is mounted on a PCB with proper soldering to ensure good electrical and thermal connections.
2. Voltage Handling: The P6KE91CA is designed to handle reverse standoff voltages up to 91V. Ensure that the operating voltage does not exceed this limit to avoid damage.
3. Pulse Current: The device can handle peak pulse currents up to 20A for short durations (8.3/400μs). Avoid continuous exposure to high currents to prevent overheating and failure.
4. Leakage Current: Monitor the reverse leakage current, which should not exceed 1μA at the rated reverse standoff voltage and room temperature.
5. Temperature Management: Operate the device within the specified temperature range (-55°C to 150°C). Exceeding these limits can lead to reduced performance or failure.
6. Capacitance Consideration: The capacitance of 270pF at 1MHz should be considered when designing circuits, especially in high-frequency applications.
7. Storage: Store the device in a dry, cool environment within the storage temperature range to maintain its performance characteristics.
8. Handling: Use appropriate ESD protection measures when handling the device to prevent damage from static electricity.
