Nexperia USA Inc. BC847BPNHF

Overview

BC847BPNHF from Nexperia is a dual NPN/PNP general-purpose transistor in SOT363 (TSSOP6) package, rated for 45 V V_CEO, 100 mA I_C, and DC current gain (h_FE) of 200–450 at 2 mA/5 V. It integrates matched transistors with low V_CE(sat) (200–850 mV), low collector capacitance (1.2–1.8 pF), and operates up to 175 °C junction temperature - used in compact bias networks and complementary switching stages in power management ICs.

For engineers reviewing the BC847BPNHF datasheet, BC847BPNHF pinout, BC847BPNHF application, or BC847BPNHF equivalent, key selection criteria include per-transistor voltage/current ratings, thermal derating on FR4 PCB, pin-compatible dual-transistor topology, and verified matching between NPN (TR1) and PNP (TR2) sections under identical bias conditions.

Technical Context

This device integrates two electrically isolated silicon planar transistors - TR1 (NPN) and TR2 (PNP) - in a single SOT363 package with no mutual interference. Each transistor supports independent operation with separate emitter, base, and collector terminals, enabling push-pull, phase-splitter, or complementary Darlington configurations.

It features tightly matched h_FE across both transistors at 2 mA/5 V, low thermal resistance (R_th(j-sp) = 170 K/W per device), and specified performance from −55 °C to +175 °C ambient, validated per IEC 60134 absolute maximum ratings and JEDEC JESD22-A108 reliability testing.

FAQ

What is the maximum allowable continuous collector current per transistor in BC847BPNHF?

The maximum continuous collector current (I_C) per transistor is 100 mA at T_amb ≤ 25 °C on an FR4 PCB with standard footprint. At elevated ambient temperatures, derating applies per Figure 1: power dissipation drops linearly to zero at 175 °C, limiting usable I_C to ~60 mA at 100 °C ambient.

How are the NPN and PNP transistors electrically isolated inside the SOT363 package?

TR1 (NPN) and TR2 (PNP) share no internal connection - their collectors, bases, and emitters are fully isolated with separate bond wires and die attach. Pinout validation confirms no shared terminals (e.g., pins 1–2–6 serve TR1; pins 3–4–5 serve TR2), preventing signal coupling or thermal crosstalk in mixed-polarity operation.

Can BC847BPNHF replace two discrete BC847B transistors in a circuit?

Yes, but only if the original design uses separate SOT23 packages and the PCB layout accommodates SOT363's 2.1 mm × 1.25 mm footprint and 6-pin mapping. Pin compatibility is not maintained - BC847B uses 3-pin SOT23, while BC847BPNHF uses 6-pin SOT363 with interleaved NPN/PNP terminals, requiring schematic and layout revision.

What is the typical transition frequency (f_T) for each transistor at 25 °C?

TR1 (NPN) has f_T = 100 MHz minimum at V_CE = 5 V, I_C = 10 mA, and 100 MHz test frequency. TR2 (PNP) shows comparable f_T ≥ 80 MHz under symmetric negative-bias conditions (V_CE = −5 V, I_C = −10 mA), confirmed in Figures 8 and 16 of the datasheet.
