That pair of resistors eliminates two external passives from the BOM, which matters when you are populating a dense board — motor-drive gate pre-drivers, relay coil drivers, or logic-level interface buffers where every component counts. The transistor itself is rated for 50 V collector-emitter breakdown and 100 mA continuous collector current, with a transition frequency of 200 MHz, so it handles the usual low-side switching and signal conditioning tasks up to that current ceiling. Infineon has placed the BCR158E6327HTSA1 in Last Buy status. That means the manufacturer is no longer accepting unlimited orders; the production window is closing, and once the final allocation is exhausted, this exact order code will not be available through the factory channel. For a BOM that depends on this pre-biased PNP, the decision is straightforward: secure the remaining inventory now through independent distribution, or qualify a replacement before the stock dries up. The base product number is BCR158, so any alternate within that family shares the same SOT-23 footprint and integrated resistor values — but the Last Buy clock is running on this specific suffix. ## 50 V, 100 mA — where this transistor fits The 50 V VCEO and 100 mA IC(max) define the safe operating area: this is not a power transistor. It is sized for the signal-level switching you find in industrial control I/O, PLC output stages, small relay or solenoid drivers, and base-drive circuits for larger bipolar transistors. The 200 mW power dissipation limit reinforces that — keep the junction temperature under control by staying within the 100 mA continuous rating and derating for ambient above 25 °C. The 200 MHz transition frequency is high enough for PWM frequencies in the tens of kilohertz without noticeable switching loss.","metaTitle":"Infineon BCR158E6327HTSA1 PNP Pre-Biased Transistor, 50 V","metaDescription":"Infineon BCR158E6327HTSA1 PNP pre-biased transistor, 50 V VCEO, 100 mA IC, 200 mW, SOT-23.

The base product number BCR158 covers a family of pre-biased PNP transistors in SOT-23 with the same integrated resistor values (R1 = 2.2 kΩ, R2 = 47 kΩ), so a different suffix within that family may be pin-compatible — but verify the exact package and tape/reel suffix against your assembly house. For a drop-in alternative from another manufacturer, look for a PNP pre-biased transistor in SOT-23 with the same 2.2 kΩ / 47 kΩ resistor divider and 50 V / 100 mA ratings."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BCR158E6327HTSA1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BCR158E6327HTSA1 when reusing this data.
