11/21/2023 0 Comments Bc557 vs bc547![]() ![]() The electrical specifications of the BC557 transistor and these transistors are almost the same, but at the practical circuits we need accurate value, so on the replacement, we need to cross-check the voltage and current specifications. The equivalent transistors at this list are equivalent, so we can replace the BC557 with these transistors. The transistor equivalent for BC557 is BC157, BC558, TIP127, BC327, and BC560. ![]() If you need the datasheet in pdf please click this link BC557 transistor Equivalent The junction temperature of the BC557 transistor is 150☌. The transition frequency value on the BC557 transistor is 100MHZ, it is important at switching applications The power dissipation at the bc557 transistor device is 625mW, this dissipation value indicates the maximum power dissipation on a device, and the BC557 transistor only had low power applications. The collector current at the BC557 transistor is -100Ma, the negative value is the indication of it is a PNP transistor, the maximum load current at BC557 is lower this is because BC557 is a general-purpose transistor. The current gain on the BC557 transistor is starting at 125 to 800Hfe, the gain value is very important at applications like an amplifier and the BC557 transistor had high gain values. BC557 DescriptionĪ BC557 transistor had general-purpose applications, this is the reason why the BC557 transistor has low voltage and low current specifications. One of the advantages of TO-92 is it is less expensive and compatible with circuits. The BC557 transistor is a general-purpose transistor type, which had more applications at the common electronic appliance, due to this the cost for a transistor is the problem. The package used to build the BC557 transistor is the TO-92, the package is made with a mixture of plastic and epoxy.
