The base resistor (R1) and the base-emitter resistor (R2) are both 47 kΩ, eliminating the need for external bias components. This saves board space and reduces BOM count in low-current switching applications where the transistor is driven directly from a logic output or microcontroller GPIO. Collector current is rated 100 mA maximum, and collector-emitter breakdown voltage is 50 V — suitable for driving relays, small solenoids, indicator LEDs, or level-shifting logic signals in 5 V and 12 V systems. The 100 MHz transition frequency is adequate for switching up to low-MHz PWM rates. Saturation voltage is 300 mV at 500 µA base drive and 10 mA collector current, which keeps conduction losses low in the on-state. The built-in 47 kΩ resistors set a fixed base current when driven from a known voltage. At 5 V logic, base current is roughly (5 V - 0.7 V) / 47 kΩ ≈ 91 µA, which with a minimum DC current gain of 70 at 5 mA gives ample drive for loads up to about 6 mA. For higher collector currents up to 100 mA, the base drive from the same resistor limits the available gain margin — the part is best suited for loads where the collector current stays under 30-50 mA in practice. ## Last-buy status — what it means for procurement The BCR148E6327HTSA1 carries a Last Buy lifecycle status. Infineon has scheduled this part for discontinuation, meaning the final production window is closing. Buyers should secure remaining inventory through independent distribution channels.","metaTitle":"BCR148E6327HTSA1 NPN Pre-Biased Transistor, 50V 100mA SOT-23","metaDescription":"Infineon BCR148E6327HTSA1 NPN pre-biased transistor with 47kΩ R1/R2, 100mA Ic, 50V Vce, 100MHz ft.

With a minimum DC current gain of 70 at 5 mA, the practical continuous collector current is lower — typically 30-50 mA — before the transistor leaves saturation. For switching 100 mA loads, consider a pre-biased transistor with a lower-value base resistor or a standard transistor with external bias."},{"question":"What is the replacement or equivalent for BCR148E6327HTSA1?","answer":"The BCR148 base product number covers a family of pre-biased transistors with different resistor values. A pin-compatible substitute would need to match the SOT-23 package and the 47 kΩ / 47 kΩ resistor pair — check other BCR148 variants or equivalent pre-biased NPN transistors from Infineon's portfolio.
