Product details

100 mA NPN pre-biased — integrated resistors save board space

The Infineon BCR142WH6327XTSA1 is an NPN pre-biased transistor in a SC-70 (SOT-323) surface-mount package. The base and emitter-base resistors are integrated on-chip — 22 kOhms (R1) and 47 kOhms (R2) — eliminating two external passives per switching node. Collector current is rated 100 mA maximum with a collector-emitter breakdown voltage of 50 V, making this part suitable for low-current load switching, relay drivers, and logic-level interface circuits where board area is tight.

Last Buy — sourcing window is closing

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. For a BOM line that depends on this exact order code, the procurement decision is time-sensitive — secure the required quantity before the last-time-buy window closes.

Frequently asked questions

Is BCR142WH6327XTSA1 obsolete?

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.

What is the replacement for BCR142WH6327XTSA1?

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.

What is the maximum collector current for BCR142WH6327XTSA1?

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.

What is the difference between BCR142WH6327XTSA1 and BCR141WH6327XTSA1?

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.
