BC817-16W

Overview

The BC817-16W is an NPN silicon general-purpose transistor manufactured by Taiwan Semiconductor Corporation. It operates with a maximum collector-emitter voltage of 45 V and supports a continuous collector current of 500 mA. The device features a minimum DC current gain (hFE) of 100, classifying it within the '16' gain bin. It is housed in a SOT-23 surface-mount package with a power dissipation rating of 310 mW at 25°C ambient temperature. The component is designed for low saturation voltage applications and is RoHS compliant.

Feature Summary

• High current capability suitable for switching loads
• Low collector-emitter saturation voltage for efficiency
• Three available current gain selections for design flexibility

Applications

• General-purpose switching circuits
• Amplifier stages
• Driver circuits for low-power loads

Procurement Notes

Verify the specific manufacturer datasheet to confirm the exact hFE range for the -16 suffix, as values may vary slightly between suppliers. Ensure the ordering part number includes the correct tape-and-reel or cut-tape designation if volume procurement is required. Confirm RoHS compliance status directly with the vendor documentation prior to finalizing specifications.

Selection Notes

Select this component when a standard NPN switch is needed with moderate current handling up to 500 mA. The -16 suffix indicates a specific gain bin; verify that the minimum gain meets the circuit requirements. Consider the SOT-23 package size for space-constrained PCB layouts. Compare against complementary PNP types like the BC807-16W for push-pull configurations.

Part Context

This device belongs to the BC817 family of NPN silicon transistors, which are widely used in consumer electronics and industrial control systems. The family offers complementary PNP counterparts, such as the BC807 series. The BC817-16W specifically denotes the version with standardized current gain characteristics, ensuring consistency across production batches for general-purpose amplification and switching tasks.

Replacement Considerations

Compatible substitutes include the BC817-16 from other manufacturers such as Nexperia, Diotec, or Infineon, provided they share the SOT-23 package and identical electrical ratings. Verify pinout compatibility and thermal characteristics before substitution.
