Product details

Pre-biased PNP for space-constrained switching

The Infineon BCR553E6327HTSA1 is a PNP pre-biased transistor in a SOT-23 package, integrating two 2.2 kOhm resistors (R1 and R2) to reduce external component count in digital switching and interface circuits. It handles a maximum collector current of 500 mA and a collector-emitter breakdown voltage of 50 V, with a transition frequency of 150 MHz. Typical applications include relay drivers, lamp drivers, and general-purpose load switching where board space is tight.

Last Buy — final procurement window

This part carries a Last Buy lifecycle status, meaning the manufacturer has announced end-of-life and is accepting final orders for a limited time. Once the last-time-buy window closes, availability will shift to surplus and broker channels. If your BOM still specifies this order code, secure inventory now or qualify a replacement before the cutoff.

Sourcing and fit for the BOM

For a BOM line using this pre-biased PNP, the key fit parameters are the 50 V VCEO and 500 mA Ic rating — sufficient for low-side switching of small relays, solenoids, or indicator loads in 12 V and 24 V industrial systems. The integrated bias resistors (2.2 kOhm base, 2.2 kOhm emitter-base) set the turn-on threshold and eliminate two external passives, saving placement cost.

Frequently asked questions

Is BCR553E6327HTSA1 obsolete?

This part is in Last Buy status, meaning the manufacturer has initiated end-of-life. Final orders are being accepted for a limited window; after that, supply will come from surplus and broker channels only.

What is the maximum collector current of BCR553?

The maximum collector current (Ic) is 500 mA.

What is the replacement for BCR553E6327HTSA1?

For a pin-compatible alternative, review other PNP pre-biased transistors in the BCR553 family (base product number BCR553) with the same SOT-23 package and 2.2 kOhm bias resistors, or contact our sourcing desk for cross-reference assistance.
