Overview
The Nexperia BC817-25W,135 is an NPN general-purpose transistor housed in a SOT323 (SC-70) surface-mount package. It supports a maximum collector-emitter voltage of 45 V and a continuous collector current of 500 mA. The device features a DC current gain range of 160 to 400 at IC = 100 mA and VCE = 1 V. Peak collector current reaches 1 A for single pulses up to 1 ms. The transition frequency is typically 100 MHz, with a total power dissipation of 200 mW at Tamb ≤ 25 °C.
Feature Summary
- High current capability suitable for demanding switching loads
- Three distinct current gain selections for precise circuit design
Applications
- General-purpose switching circuits
- Amplification applications
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details and manufacturing site codes. Ensure the selected variant matches the required gain binning and package type for your assembly process. Confirm that the component status aligns with your production timeline requirements before finalizing procurement orders.
Selection Notes
Select this component when a compact SOT323 footprint is required alongside moderate current handling capabilities. The BC817-25W variant provides a specific hFE range of 160 to 400, distinguishing it from other gain bins within the series. Verify thermal management needs based on the 200 mW dissipation limit in free air conditions.
Part Context
This device belongs to the BC817W series of NPN general-purpose transistors manufactured by Nexperia. It serves as the complementary counterpart to the BC807-25W PNP transistor. The series is designed for surface-mount technology, offering a small plastic package solution for modern electronic assemblies requiring reliable bipolar junction transistor performance.
