PDF reference for the 2SD892 at 54.3 KB, named with an undefined _E suffix and indexed among schematics. The 2SD prefix in Japanese JIS numbering marks an NPN bipolar transistor of the low-frequency type, so the document is a part specification. Technicians open it to check which pin is which, read breakdown voltage and collector current limits, and compare characteristics with possible equivalents. Confirm the printed marking on the removed component matches before using the data.
