Understanding Transistor Data and Replacement

If for any reason, you can not get an appointment replacement for the transistor would replace, can relate to one of transistors or replacement of the guide, and try to identify the end of a replacement . Attention, however. The replacement of the guide and a roster replacement for their part, even if both parties are not very similar. The most widely used transistor replacement guides are ECG semiconductors Philips Master Guide substitution. Choosing the right transistor parameters or specifications for the equipment you want to avoid repair reminders to customers. Tilbakeanrop repairs or because of repeated bad transistor replacement would cost more money and a waste of time. Significant transistor parameters are as follows: a maximum of collector-base voltage (VCBO)? The piece must have an opinion VCBO equal to or greater than the original. Maximum collector-emitter voltage (LCA)? The piece must have an opinion VCE equal to or greater than the original. Maximum issuer in terms of voltage (EBV)? The piece must have an opinion Veba equal to or greater than the original. Maximum collector current (CI)? The play must be able to deal with two (or more) collector current as the original. The proliferation of energy (PD Watts)? The play must be able to disseminate as much (or more) power than the originals. Get (HFE)? The replacement must have an income equal to or greater than the original, and it should be as close to the original specification as possible. Revenue-width banda (FT)? replacement must be a transition frequency equal to or greater than the original, and it should be as close to the original specification as possible. You will find below a table for the implementation and the requirements of the specification important that you can use the guidelines as to when it comes to replace the transistor. Requirements for application and specifications IMPORTANT 1. In general purpose amplifier and low-level switching transistors. Spec-HFE, CI (max), FT VCE 2. Power switching applications. Spec-VCE, VCBO, HFE, CI (max), DP (max) 3. Low FI / RF amplification. Spec-IC (max), FT VCE 4. Audio amplifier. Spec-IC (max), DP (max), HFE, VCE 5. Transistorer high tension. Spec-VCE, VCBO, CI (max), Ft keep in mind that the compensation transistor must not go hot and if the problem persists, try another number or compensation to get the number if possible. Do not ignore the fact that the surrounding components can also be caused transistor to run the heat, even if the number is used. Jestine Yong is an electronics repair shop and a writer.
