1AM, 2A, or 8050 and 8550TO92 packages with SMD, as long as the polarity is observed.

If you look for a series, there should be an alternative, but if you don't have a patch, can you use it in the position of the original patch? The pads should be different

A1SHB FET, the model is P-channel FET, and the replacement models are as follows: 212T S, A1, H1SP, 016H X, SO16Y, M21, PJ2301, PJ2305, XP152A, SI2301, SI2305, AO3401

You can go directly to change an A1SHB, the model is PW2301A, it's a very ordinary chat.
A1SHB.

A1SHB This component is a field effect transistor in the MP4 boot circuit, and the model number is SI2035.
It usually works with the 8050! It's a P-channel MOS tube.

I have one of this patch FETs. What is the difference between A1 and A1SHB.

Model number : S8050 .
Description : low voltage high.
Encapsulated from: SOT-23.
J3Y is composed of two N-type semiconductors sandwiched between a P-type semiconductor, the PN junction formed between the emission region and the base region is called the emission junction, and the PN junction formed between the collector region and the base region is called the collector junction, and the three leads are called emitter E, base B and collector C respectively.

A patch transistor typed as J3Y.
BAI this is imprinted as DUJ3Y, and its model is the DAOS8050 of the triode ZHI tube.
High power back. The power of the transistor is generally more than 1W, and this kind of transistor often causes the temperature in the chip to be too high when working due to the relatively large power dissipation, so it is usually necessary to install a heat sink to ensure that the transistor has good heat dissipation.
The characteristic frequency of low-frequency transistor is generally less than 3MHz, and this transistor is mostly used in low-frequency amplification circuits, such as radio power amplifier circuits.
The crystal triode with metal package mainly includes B-type, C-type, D-type, E-type, F-type, and G-type, among which low-power transistor (mainly high-frequency and low-power transistor) is mainly in B-type packaging, and F-type and G-type packaging are mainly used for low-frequency and high-power transistors.
A phototransistor is an optical-electrical conversion device with amplification ability, so it has higher sensitivity than a photodiode. It should be noted that phototransistors have both 3 pins and 2 pins, so pay attention to distinguish them when using them, and do not mistake them for 2-pin phototransistors.

BAI is DU based on the inscription on the transistor alone
There is no way to accurately determine the zhi of the model, which is not the same as the dao printing on the resistor.
concepts. The lettering on the transistor is all.

Isn't the 9015 SMD, SOT32 packaged? The number printed on the SMD triode is different from the number printed on the in-line transistor.
Evidence: Take the midpoint M of AC and connect PM, because PA=PC, PAC is an isosceles triangle, and PM is the midline of PAC, so PM is perpendicular to AC. If BM is connected, there is AM=BM, because PA=PB, PM=PM, so PAM is all equal to PBM, so PMA= PMB=90°, that is, PM is vertical BM. >>>More
