Nexperia USA Inc. BC847BPN/DG/B4X

Overview

BC847BPN from Nexperia is a dual NPN/PNP general-purpose transistor pair in a single SOT363-3 (TSSOP6) package, rated for 45 V V_CEO, 100 mA I_C, and featuring matched h_FE (200–450), low V_CE(sat) (≤300 mV), and isolated operation-used in compact-level signal switching and complementary amplification circuits on space-constrained PCBs.

For engineers reviewing the BC847BPN datasheet, BC847BPN pinout, BC847BPN application, or BC847BPN equivalent, this device serves as a verified dual-transistor solution where board area reduction, mutual isolation, and consistent gain matching across complementary stages are design-critical requirements.

Technical Context

This dual transistor integrates one NPN (TR1) and one PNP (TR2) device in a monolithic SOT363-3 package with electrically isolated die-enabling independent biasing without crosstalk. Each transistor supports DC current gain (h_FE) of 200–450 at I_C = 2 mA and V_CE = 5 V, with f_T ≥100 MHz for both devices under specified conditions.

Thermal performance is defined for two mounting configurations: standard FR4 footprint (R_th(j-a) = 568 K/W per transistor) and enhanced pad layout (R_th(j-sp) = 230 K/W per device). Absolute maximum ratings include V_CBO = 50 V, V_EBO = 5 V, and T_j = 150 °C.

FAQ

Is BC847BPN suitable for automotive applications?

No. BC847BPN is not AEC-Q101 qualified and lacks automotive-grade qualification, testing, or extended temperature validation beyond −65 °C to +150 °C ambient. It is intended for commercial and industrial applications only; automotive use requires explicit Nexperia automotive-qualified equivalents such as the PBSS4041PAN series.

What is the maximum continuous current per transistor in BC847BPN?

The maximum continuous collector current per transistor is 100 mA at T_amb ≤ 25 °C with appropriate PCB thermal relief. At elevated temperatures, current must be derated per the power dissipation curves-e.g., ≤60 mA at 75 °C ambient with standard FR4 mounting (250 mW limit).

Can BC847BPN replace two separate BC847B transistors?

Yes-functionally and electrically, BC847BPN replicates the performance of two discrete BC847B transistors (one NPN, one PNP) while adding guaranteed h_FE matching and eliminating inter-device layout variability. However, pinout differs: SOT363-3 uses 6 pins vs. two SOT23 packages, requiring PCB layout revision.

Does BC847BPN support pulsed operation above 100 mA?

Yes-peak collector current is rated at 200 mA for single pulses ≤1 ms (duty cycle ≤2%). This allows short-duration surge handling in motor gate drivers or LED strobing, provided average power remains within 250–400 mW limits and thermal impedance is managed via proper PCB copper area.
