The base and emitter-base resistors are integrated on-chip — 22 kOhms (R1) and 47 kOhms (R2) — eliminating two external passives per switching node.
Infineon has placed the BCR142WH6327XTSA1 in Last Buy status. That means the manufacturer has announced a final production run; once that inventory is consumed, no further factory orders will be accepted.
Infineon lists the BCR142WH6327XTSA1 as Last Buy, meaning it is in the final production phase and will become obsolete once the last-time-buy inventory is depleted. It is not yet fully discontinued, but the end-of-life process has begun.
A pin-compatible alternative would need to be selected from the same pre-biased NPN transistor family with matching 22 kOhms base and 47 kOhms emitter-base resistor values, such as the BCR141WH6327XTSA1 (which uses different resistor ratios). Validate the resistor divider and package footprint before substituting.
The maximum collector current (Ic) is 100 mA. This is the continuous current rating; for pulsed or high-duty-cycle applications, refer to the power dissipation limit of 250 mW and the thermal characteristics of the SC-70 package.
Both are NPN pre-biased transistors in SC-70 packages, but the BCR142 uses a 22 kOhms base resistor (R1) and 47 kOhms emitter-base resistor (R2), while the BCR141 uses different resistor values. The resistor ratio determines the input threshold and saturation drive — check your base-drive requirements before swapping.
