How To Read Transistors Datasheet


Type of Control Channel: N Or P Channel
Vds : Maximum Drain-Source Voltage
Pd : Maximum Power Dissipation
Vgs : Maximum Gate-Source Voltage
Id : Maximum Drain Current
tr : Rise Time 0.01 ns for example
Cd : drain-source capacitance for example 600 pf
Rds : maximum drain-source on-state resistance 0.01 ohm for example

In a power MOSFET, the gate is insulated by a thin silicon oxide. Therefore, a power MOSFET has capacitances between the gate-drain, gate-source and drain-source terminals as shown in


Polarity: NPN
Pc : Maximum Collector Power Dissipation
Vcb : Maximum Collector-Base Voltage
Vce : Maximum Collector-Emitter Voltage
Veb : Maximum Emitter-Base Voltage
Ic : Maximum Collector Current
ft : Transition Frequency The transition frequency describes how the transistor’s current gain is affected by the input frequency. This is a low pass effect, so frequencies beyond 600 kHz on the original part or 4 MHz on the new one would start to be attenuated. Audible frequency range is 20 Hz – 20 kHz which is far below the transition frequency of both parts. No effects should be noticeable
Cc : Collector Capacitance
hfe : Forward Current Transfer Ratio
