Infineon Technologies BC848BE6327HTSA1

Overview

BC848BE6327HTSA1 from Infineon Technologies is an NPN silicon general-purpose bipolar junction transistor (BJT) designed for audio-frequency input stages and driver circuits. It delivers high DC current gain (h_FE = 200–450 at I_C = 2 mA), low V_CE(sat) (max 250 mV at I_C = 10 mA / I_B = 0.5 mA), and low noise (F = 1.2–4 dB at 1 kHz), making it suitable for low-noise preamplifier and signal buffering applications in automotive and industrial electronics.

For engineers reviewing the BC848BE6327HTSA1 datasheet, BC848BE6327HTSA1 pinout, BC848BE6327HTSA1 application, or BC848BE6327HTSA1 equivalent, key selection criteria include its AEC-Q101 qualification, SOT-23 package compatibility, h_FE group B specification, and thermal resistance (R_thJS ≤ 240 K/W) for reliable operation in space-constrained PCB layouts.

Technical Context

This transistor operates as a linear amplifying device with fixed-emitter bias configuration in common-emitter topology. Its design emphasizes low-noise performance across 30 Hz–15 kHz and stable h_FE over temperature (−65 °C to +150 °C junction range), supported by complementary PNP types (e.g., BC857B) for push-pull stage implementation.

It features a maximum V_CEO of 30 V, V_CBO of 30 V, and I_C rating of 100 mA - enabling use in low-voltage, medium-current switching and analog amplification where saturation voltage and gain consistency are critical.

FAQ

Is BC848BE6327HTSA1 pin-compatible with BC847B or BC849B?

Yes - all three share identical SOT-23 pinout (E-B-C) and mechanical footprint. However, BC848B has V_CEO = 30 V (vs. 45 V for BC847B and 30 V for BC849B), so substitution requires verifying voltage margin in the target circuit's worst-case operating conditions.

What is the maximum continuous collector current at 100 °C ambient?

At T_A = 100 °C, derated power dissipation limits I_C to approximately 65 mA (based on P_tot = 330 mW at T_S ≤ 71 °C and R_thJA ≈ 300 K/W). Full 100 mA rating applies only when case temperature remains ≤71 °C.

Does BC848BE6327HTSA1 support pulsed operation beyond its DC ratings?

Yes - pulse testing (t_p ≤ 10 ms, duty cycle < 2%) allows peak I_C up to 200 mA. The permissible pulse load curve (Fig. EHP00362) confirms safe operation at 10× DC current for sub-millisecond durations with appropriate thermal recovery time.

How does the "E6327" suffix affect packaging and marking?

The "E6327" denotes Infineon's tape-and-reel packaging standard: 3,000 units per reel, 12 mm tape width, and embossed carrier tape. The top-side marking "1K" identifies the BC848B variant per Infineon's SOT-23 marking convention, confirmed in the Pin Configuration table.
