Nexperia USA Inc. BC846BPNHF

Overview

BC846BPNHF from Nexperia is an NPN/PNP general-purpose double transistor in a SOT363 (TSSOP6) surface-mount package, rated for 65 V V_CEO, 100 mA I_C, and DC current gain (h_FE) of 200–450 at 2 mA/5 V. It integrates matched complementary transistors on one die with no mutual interference, enabling compact dual-polarity switching in space-constrained consumer and industrial control circuits.

For engineers reviewing the BC846BPNHF datasheet, BC846BPNHF pinout, BC846BPNHF application, or BC846BPNHF equivalent, this device supports high-temperature operation up to 175 °C, offers low V_CE(sat) (200–300 mV at 100 mA), closely matched h_FE, and reduced board footprint versus discrete pairs - critical for power management, level-shifting, and push-pull driver designs.

Technical Context

This dual transistor integrates one NPN (TR1) and one PNP (TR2) silicon planar epitaxial device in a single SOT363 package. Each transistor operates independently with isolated thermal and electrical paths, supporting simultaneous sourcing and sinking in complementary configurations without crosstalk.

It delivers 100 MHz f_T for both transistors at 10 mA/5 V, low collector capacitance (1.2 pF for TR1, 1.8 pF for TR2), and stable h_FE across −40 °C to 175 °C - enabling reliable small-signal amplification and fast-switching applications where thermal robustness and parameter matching are essential.

FAQ

What is the maximum allowable power dissipation for BC846BPNHF at 100 °C ambient?

At 100 °C ambient, the device's per-device P_tot is derated from 400 mW (25 °C) using the 375 K/W R_th(j-a). With T_j(max) = 175 °C, the allowable power is (175 − 100) / 375 ≈ 200 mW. This assumes mounting on FR4 PCB with single-sided 35 µm copper and standard footprint per datasheet Fig. 1.

Can BC846BPNHF be used in linear amplification mode with stable gain?

Yes - BC846BPNHF supports linear operation with h_FE variation <±15 % from 1 mA to 50 mA at 25 °C (Fig. 3 & 11), and its 100 MHz f_T enables bandwidth up to ~10 MHz in common-emitter configurations. However, thermal drift must be managed: h_FE decreases ~0.5 %/°C above 25 °C, requiring emitter degeneration for bias stability.

How does the pinout support complementary push-pull configuration?

Pins 1–2–6 form the NPN (TR1) with emitter-base-collector order; pins 3–4–5 form the PNP (TR2) with collector-emitter-base order. This arrangement allows direct connection of TR1 collector (pin 6) and TR2 emitter (pin 4) to the same output node, while TR1 emitter (pin 1) and TR2 collector (pin 3) connect to opposing rails - enabling true push-pull without external wiring inversion.

Is BC846BPNHF qualified for automotive applications?

No - BC846BPNHF is not AEC-Q101 qualified. While it operates up to 175 °C junction temperature and meets industrial reliability standards, Nexperia explicitly states in its legal disclaimers that non-automotive qualified parts are not tested to automotive stress requirements and carry no warranty for use in safety-critical or life-support systems.
