Overview
The BC817-25W-AQ is an NPN general-purpose bipolar junction transistor manufactured by Diotec Semiconductor. It utilizes a SOT-323 surface-mount package and operates with a maximum collector current of 500 mA and a collector-emitter voltage (VCEO) of 45 V. The device features a DC current gain (hFE) group -25, ranging from 160 to 400 at IC = 100 mA. Key electrical parameters include a power dissipation of 200 mW, a transition frequency (fT) of 100 MHz, and a collector-base cutoff current of 100 nA. The component supports a junction temperature range of -55°C to +150°C.
Feature Summary
- Three distinct current gain groups available for precise amplification control
- Compliant with RoHS directives and REACH regulations
- Designed for commercial and industrial grade applications
Applications
- Signal processing circuits
- General-purpose switching
- Amplification stages
Procurement Notes
Verify the specific suffix status during procurement. The datasheet indicates that the -AQ suffix denotes the component is in AEC-Q101 qualification rather than fully compliant. Confirm final automotive qualification status directly with Diotec Semiconductor before integrating into certified automotive designs.
Selection Notes
Select this component when a small SOT-323 footprint is required for medium-power NPN switching or amplification. Ensure the design accommodates the 200 mW power dissipation limit and verify that the hFE group -25 characteristics align with the circuit's biasing requirements.
Part Context
This part belongs to the BC817W series of SMD general-purpose NPN transistors. It serves as the complement to PNP devices such as the BC807W. The standard commercial version is designated as BC817-25W, while the -AQ variant represents the specific ordering code for the unit undergoing automotive qualification processes.
