Overview
The BC817-25W-Q is an NPN general-purpose transistor manufactured by Nexperia, housed in a compact SOT323 (SC-70) surface-mount package. It supports a maximum collector current of 500 mA and withstands a collector-emitter voltage of 45 V. The device features a DC current gain range of 160 to 400 at VCE = 1 V and IC = 100 mA. It operates within a temperature range of -65 °C to +150 °C and is qualified according to AEC-Q101 standards for automotive applications.
Feature Summary
- Qualified for automotive applications under the AEC-Q101 standard
- Provides high current capability with a continuous collector current rating of 500 mA
- Offers three distinct current gain selection groups for design flexibility
Applications
- General-purpose switching circuits
- Amplification stages
- Automotive electronic systems
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact tape-and-reel packaging configuration and manufacturing site code. Ensure that the component meets the required AEC-Q101 qualification status for your intended automotive application before finalizing procurement orders.
Selection Notes
Select this component when a small SOT323 footprint is required alongside robust automotive reliability standards. The BC817-25W-Q variant provides a specific hFE range of 160 to 400, which is suitable for designs requiring moderate-to-high current amplification without excessive base drive requirements.
Part Context
This part belongs to the BC817W-Q series of NPN general-purpose transistors designed for space-constrained surface-mount applications. It serves as the NPN counterpart to the BC807W-Q PNP series, allowing for complementary push-pull configurations in low-power signal processing and switching tasks within automotive environments.
Replacement Considerations
Direct functional equivalents within the same series include BC817-16W-Q and BC817-40W-Q, which share identical packages and ratings but differ in DC current gain ranges. Verify that the alternative gain specifications align with your circuit's biasing requirements.
