What is the collector voltage of a h1061 transistor?

What is the collector voltage of a h1061 transistor?

H1061 Datasheet, Equivalent, Cross Reference Search. Transistor Catalog Maximum Collector Power Dissipation (Pc): 40 W Maximum Collector-Base Voltage |Vcb|: 100 V Maximum Collector-Emitter Voltage |Vce|: 80 V Maximum Emitter-Base Voltage |Veb|: 5 V Maximum Collector Current |Ic max|: 4 A Max. Operating Junction Temperature (Tj): 150 °C

Is it necessary to replace a transistor with the same material?

As bias voltages and other features are different it is necessary to select a replacement transistor with the same material. Select the same functional type of transistor: Transistors are normally given an indication of their application in the datasheets. The replacement should have the same application if possible.

How can you tell if a transistor is silicon or germanium?

Silicon or germanium: It is important to find out whether the transistor is silicon or germanium. It may be possible to discover this in a number of ways. If the original transistor is still working then this can be discovered by measuring the voltage across the base emitter junction when it is forward biased.

What is the maximum collector current in a transistor?

Maximum Collector Current |Ic max|: 4 A Max. Operating Junction Temperature (Tj): 150 °C Forward Current Transfer Ratio (hFE), MIN: 60

Can a substitute transistor be as high as the original?

Choose a substitute transistor with a maximum power rating at least as high as the original. Current gain is only occasionally significant when choosing a substitute transistor. Actual circuit gain depends on other components. But if the original transistor has a high gain, try to match it.

Where do you find the type number on a transistor?

Transistors are given registered type numbers by the Joint Electron Device Engineering Council (JEDEC). The type number is often printed on the transistor, although product manufacturers sometimes have their own part numbers printed instead. In that case,…

How do you replace a transistor in a circuit board?

If the lead arrangement of a small replacement transistor differs from that of the original, you can sometimes bend the transistor leads across one another to route them into the correct holes in the circuit board. Just use a bit of spaghetti tubing on the leads to keep them from touching each other.

Where can I find transistor cross reference guide?

In that case, the product’s Service Manual or Parts List might provide you with the transistor type. If you don’t have that particular type, a transistor cross-reference guide can sometimes help you to find a compatible, generic part. The NTE Cross Reference is a good example – NTE branded replacements are widely available.
