Nexperia USA Inc. BC847BSH-QX

Overview

BC847BSH-QX from Nexperia is an AEC-Q101-qualified NPN/NPN double transistor in SOT363 (TSSOP6) package, rated for 45 V V_CEO, 100 mA I_C, and 175 °C junction temperature. It delivers closely matched h_FE (200–450), low V_CEsat (200 mV typ. at 100 mA), and <1.2 pF collector capacitance - enabling compact dual-transistor switching in automotive body control modules.

For engineers reviewing the BC847BSH-QX datasheet, BC847BSH-QX pinout, BC847BSH-QX application, or BC847BSH-QX equivalent, this device supports high-temperature dual-gain-matched amplification and switching where board space, thermal robustness, and automotive qualification are critical selection criteria.

Technical Context

This dual NPN transistor integrates two electrically isolated gain-matched transistors in a single SOT363 package, eliminating mutual interference while maintaining independent base-emitter and collector-emitter paths. Each transistor supports DC current gain of 200–450 at 2 mA/5 V and operates up to 175 °C junction temperature.

Its 1.2 pF collector capacitance and 100 MHz f_T support stable small-signal amplification up to mid-RF frequencies, while low 200 mV V_CEsat at 100 mA/5 mA drive enables efficient switching in 3.3 V–5 V logic-level interfaces.

FAQ

What is the maximum continuous collector current per transistor in BC847BSH-QX?

The BC847BSH-QX supports 100 mA continuous collector current per transistor under standard conditions (T_amb ≤ 25 °C on FR4 PCB). At elevated ambient temperatures, derating applies per Figure 1: power dissipation drops linearly above 25 °C, limiting usable I_C to maintain T_j ≤ 175 °C.

Does BC847BSH-QX support operation at 150 °C ambient temperature?

Yes - BC847BSH-QX is rated for ambient temperatures from –55 °C to +175 °C and qualified for 175 °C junction operation. At 150 °C ambient, its per-transistor I_C must be reduced to ~45 mA (based on R_th(j-a) = 375 K/W and P_tot = 400 mW) to avoid exceeding T_j = 175 °C.

How are the two transistors isolated inside the SOT363 package?

The BC847BSH-QX integrates two physically separate silicon die in a single SOT363 mold compound, with fully independent emitter, base, and collector terminals. Electrical isolation is confirmed by zero mutual interference in switching and amplification tests, and by absence of shared substrate or parasitic coupling paths in the device construction.

Can BC847BSH-QX replace two discrete BC847BW transistors on the same PCB?

Yes - BC847BSH-QX replaces two SOT323-packaged BC847BW transistors with identical electrical specs (45 V V_CEO, 100 mA I_C, h_FE 200–450), while reducing board area by ~50% and eliminating placement/tolerance variation between devices. Pin compatibility requires adapting layout to SOT363 footprint and verifying thermal relief for 400 mW total dissipation.
