MJE13001 NPN Power Transistor

From the shop's description

The MJE13001 is a common BJT NPN switching transistor that is found in lamp ballasts and (cheap) phone chargers because of its high breakdown voltage and current capacity. It comes both in an SMD SOT-89 variant and a TO-92 THT variant. MJE13001 Pinout Description Pin Number Pin Name Description 1 Base Current into this terminal controls conduction between the collector and emitter 2 Collector Current flows into this terminal 3 Emitter Current flows out of this terminal Features and Specifications 600V collector-emitter breakdown 200mA collector current Current gain of up to 70 SOT-89 and TO-92 package Power dissipation 750mW (TO-92), 550mW (SOT-89) Note: Complete technical details can be found in the MJE13001 datasheet linked at the end of this page. Equivalent APT13005D, MJE13007 How To Use MJE13001 The MJE13001 is an NPN bipolar transistor featuring a high breakdown voltage of 600V between the collector and emitter and a medium emitter current of 200mA. The high breakdown voltage and current-carrying capability make it particularly suited for low-power SMPS and lamp ballasts . It can also be used to switch loads at high voltages. Since this is a high voltage transistor , it has a few differences when compared to a lower voltage transistor. The first is the high base-emitter voltage of up to 1.1V, instead of the usual 0.6V. This must be accounted for when designing the driving circuitry. The cut-off current is also relatively high – 200uA when there is no base-emitter bias. This might cause problems upstream, and should be taken into account. The storage time is specified as 1.5us, meaning the transistor takes at least 1.5us to turn off after being turned on. This can be mitigated to some extent by adding a capacitor parallel to the base resistor to quickly remove current from the transistor base.
