Nexperia USA Inc. BC847BPN,135

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_CEsat (≤300 mV), and isolated operation-used in compact level-shifting, complementary switching, and bias networks in portable power management.

For engineers reviewing the BC847BPN datasheet, BC847BPN pinout, BC847BPN application, or BC847BPN equivalent, this device supports dual-polarity signal control in space-constrained PCBs where thermal isolation, gain matching, and low saturation voltage are critical selection criteria.

Technical Context

This dual-transistor device integrates one NPN (TR1) and one PNP (TR2) transistor in a monolithic SOT363-3 package with electrically isolated die-enabling complementary switching without cross-talk. Each transistor operates independently with separate base-emitter-collector terminals and shares no internal connection.

TR1 delivers f_T = 100 MHz at I_C = 10 mA, V_CE = 5 V; TR2 achieves comparable high-frequency response (f_T = 100 MHz) under negative bias (V_CE = −5 V). Both exhibit low C_c (1.5 pF / 2.2 pF) and tightly controlled V_BE (655 mV typ. for both polarities), supporting stable biasing across temperature.

FAQ

What is the maximum safe operating temperature for BC847BPN?

The BC847BPN has a maximum junction temperature (T_j) of 150 °C and storage temperature range of −65 °C to +150 °C. When mounted on an FR4 PCB with standard footprint, its thermal resistance R_th(j-a) is 568 K/W-so at 25 °C ambient and 250 mW dissipation, junction temperature reaches ~170 °C, exceeding rating. Derating is required above 25 °C ambient per Fig. 1.

Can BC847BPN be used in linear amplifier mode?

Yes-both transistors support linear operation with V_CE = 5 V, I_C = 2 mA, and h_FE = 200–450. The matched gain and low V_BE variation (±75 mV) enable stable DC-coupled differential pairs. However, f_T = 100 MHz limits usable bandwidth to <10 MHz for low-distortion amplification.

Is BC847BPN automotive qualified?

No-BC847BPN is not AEC-Q101 qualified. The datasheet explicitly states it is a non-automotive qualified product, with no testing performed per automotive reliability standards. It must not be used in safety-critical or life-support systems without additional validation and risk mitigation by the end customer.

How does the pinout differ from standard SOT-363 dual transistors?

BC847BPN uses a non-standard pin mapping: Pin 1 = E1, Pin 2 = B1, Pin 3 = C2, Pin 4 = E2, Pin 5 = B2, Pin 6 = C1. This differs from common dual-NPN layouts (e.g., BC847BU) and requires careful schematic symbol assignment and PCB layout verification-especially since C1 and C2 are on opposite ends (Pins 6 and 3).
