Product details

What this pre-biased NPN does on your board

It integrates two 4.7 kOhm resistors — one in series with the base (R1) and one between base and emitter (R2) — so you can drive it directly from a logic output or microcontroller GPIO without adding external bias components. This saves two resistors per transistor and shrinks the placement footprint to a single three-pin SOT-23.

Key ratings for the design decision

Collector current is rated 100 mA maximum, with a collector-emitter breakdown voltage of 50 V. The 140 MHz transition frequency means it handles switching up into the low-MHz range — fine for relay drivers, LED switching, or level translation at typical logic speeds. Collector cutoff leakage is 100 nA maximum, negligible for most loads.

Lifecycle status — last buy window

Infineon has announced end-of-life and is accepting final orders through a defined last-time-buy window.

Frequently asked questions

Is BCR112E6327HTSA1 obsolete?

BCR112E6327HTSA1 has a Last Buy lifecycle status. It is not yet fully discontinued — Infineon is still accepting final orders through a last-time-buy window — but production will end after that window closes. Plan your procurement accordingly.

What is BCR112E6327HTSA1's power dissipation rating?

The maximum power dissipation is 200 mW for the device in the PG-SOT23 package. This limits the continuous collector current and switching duty cycle you can sustain without exceeding the junction temperature.
