How to test a 2n3055 transistor how to#
It will be awhile before I will have all of the components to build the target project so I would like to know how to test the 2N3055 transistors. Values of VCES, VBE, ICEO and BVCEO exceed the limit, meanwhile indicating the unqualified item I purchased some 2N3055 transistors through eBay today and they were manufactured in India by Continental Device India Limited.
How to test a 2n3055 transistor series#
It is intended for power switching circuits, series and shunt regulators, output stages and high fidelity amplifiers. I would like to inprove this in order to flaten the signal. 2N3055 SILICON NPN TRANSISTOR SGS-THOMSONPREFERRED SALESTYPE DESCRIPTION The 2N3055 is a silicon epitaxial-base NPN transistor in JedecTO-3 metalcase. B/PG 2N3055 Power Transistor (NPN) of 4 Dimensions in mm TO-3. 1.5-2 A at 60 V for a few seconds) and see if they survive. Pulse Test: Pulse Width300µs, Duty Cycle2. It is more like give it a stress test (e.g. The Darlington pairs can be paralleled for higher current capability. The collector-current rating of a single Darlington pair is 500 mA.
How to test a 2n3055 transistor full#
No need to record a full curve and find the real limit. The ULN2003A is a high-voltage, high-current Darlington transistor array consisting of seven NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads.
So the interesting point is more like how to do an SOA test.
In order to convert incoming signal from PWM into a integrated signal, I built up this Rc filter, I can see is not the best one because R2 is too high and its take to long to become stable. If they are fake / wrong type, the main parameter to worry about is the voltage rating / SOA (e.g. The hFE or beta is used for a linear amplifier that has plenty of collector to emitter voltage and for the 2N3055 it is a minimum hFE of only 5 when its collector current is 10A and its collector to emitter voltage is at least 4V. An arduino creates a signal via analogWrite, ino file included in sources. As output a DC motor with full variable values, current will vary depending on the resistance applyed on the rotor, and voltage by the PWM.
