FAQ

What is the recommended device sequencing for turning the MAGX-001214-650L00 ON?

Set VGS to pinch-off (typically -5 V), turn on VDS to nominal voltage (50 V), increase VGS until IDS current is reached, then apply RF power.

How does junction temperature affect the Mean Time To Failure (MTTF)?

MTTF is significantly higher when TJ is kept below 200°C (5.3 x 10^6 hours) compared to operation near the maximum limit of 250°C (6.8 x 10^4 hours).

What is the absolute maximum drain-source voltage rating?

The absolute maximum drain voltage (VDD) is rated at +65 V.
