About this app

Find the right bipolar transistor without searching through dozens of websites.

Bipolar Transistor Database contains more than 50,000 transistor records and works offline. Search by part number or filter components using the electrical parameters you already know.

Features:

• Search by full or partial part number
• Filter by collector voltage, current, power and gain
• Find devices by transition frequency (fT)
• View important specifications in one place
• Open external datasheets when more information is needed

Useful for electronics repair, component identification, circuit design, students and radio amateurs.

Component search works without an internet connection. Internet access is required only when opening an external datasheet.
Search 50,000+ BJT transistors by specifications—even without internet.

good very good. on main page (parameters) need a button to clear all previous data. when searching multiple transistors, the old data of previous transistor remains behind and interferes with the data for the new search. 1 clear all fields button will do the trick.
