The document provides detailed specifications for the BDW 25, BDY 12 and BDY 13 epitaxial NPN silicon planar power transistors in SOT‑9 case. It includes maximum ratings, static and dynamic electrical characteristics, thermal data and ordering information.
Key features include high collector‑emitter breakdown voltages, low saturation voltages, and suitable mounting accessories such as mica washers and insulating nipples. The data are presented for typical operating conditions at 25 °C.
| Maximum power dissipation (Ptot) | 26 W |
|---|---|
| Maximum junction temperature (Tj) | 175 °C |
| Mounting accessories | Mica washer and two insulating nipples (ordered separately) |
Each transistor can dissipate up to 26 W under the specified conditions.
A mica washer and two insulating nipples are required and must be ordered separately.
