MJE521 Overview

As explained above, DC current gain takes into account the rate at which the base current flows through the collector current; therefore, DC current gain for this device is 40 @ 1A 1V.Emitter base voltages of 4V can achieve high levels of efficiency.A fuse's current rating indicates how much current it will be able to carry over an indefinite period, and this device has a current rating of (4A).10MHz is present in the transition frequency.Single BJT transistor can take a breakdown input voltage of 400V volts.In extreme cases, the collector current can be as low as 4A volts.
