Product details

NPN transistor in SOT-23 — what it does

The Infineon BC 817-16 E6327 is a general-purpose NPN transistor in a small SOT-23-3 (PG-SOT23) surface-mount package. It handles a collector current up to 500 mA and a collector-emitter breakdown voltage of 45 V, with a transition frequency of 170 MHz. The 330 mW power dissipation limit suits low-to-moderate drive stages, signal amplification, and load switching on compact boards.

Key ratings for the BOM decision

The 45 V VCEO rating covers most industrial and telecom supply buses. The 500 mA continuous collector current handles relay coils, small solenoids, and LED strings without needing a heat sink at room ambient.

Package and reflow considerations

The SOT-23 (PG-SOT23) footprint is standard — three leads. No exposed pad, so the 330 mW dissipation limit is the junction-to-ambient ceiling.

Obsolete — sourcing reality

Infineon lists the BC 817-16 E6327 as obsolete.

Frequently asked questions

What is the replacement for BC 817-16 E6327?

Infineon has not published an official successor order code for the BC 817-16 E6327. The BC 817 base number remains active in other gain-group variants (e.g., BC 817-25), but those differ in hFE binning. A direct drop-in replacement within the same -16 gain group would need to be qualified from the available surplus stock or from a different manufacturer's equivalent NPN in SOT-23 with matching 45 V, 500 mA ratings.

What are the specifications of BC 817-16 E6327?

It is an NPN transistor with 45 V VCEO, 500 mA maximum collector current, 170 MHz transition frequency, 330 mW power dissipation, and a minimum DC current gain (hFE) of 100 at 100 mA, 1 V. It comes in a SOT-23-3 (PG-SOT23) surface-mount package and operates at a junction temperature up to 150 °C.
