Nexperia USA Inc. BC856BSHF

Overview

BC856BSHF from Nexperia is a PNP/PNP general-purpose double transistor in SOT363 (SC-88) package, rated for −65 V V_CEO, −100 mA I_C, and 200–450 h_FE per transistor. It delivers matched gain, low V_CE(sat) (−200 mV typ. at −100 mA), and operates up to 175 °C junction temperature-used in compact dual-switching stages of power management and signal routing circuits.

For engineers reviewing the BC856BSHF datasheet, BC856BSHF pinout, BC856BSHF application, or BC856BSHF equivalent, this device supports space-constrained dual-PNP switching with thermal robustness, low inter-transistor crosstalk, and validated performance across −55 °C to +175 °C ambient conditions.

Technical Context

This dual PNP transistor integrates two electrically isolated, closely matched transistors in one monolithic die housed in a 6-pin TSSOP package. Each transistor shares identical absolute maximum ratings and DC characteristics-including −65 V V_CEO, −100 mA I_C, and h_FE = 200–450 at −2 mA I_C.

No mutual interference is guaranteed by internal isolation; thermal resistance R_th(j-a) is 375 K/W per device on FR4 PCB, enabling stable operation in high-density industrial control modules where board area and thermal headroom are constrained.

FAQ

What is the maximum continuous collector current per transistor in BC856BSHF?

The BC856BSHF is rated for −100 mA continuous collector current per transistor under T_amb ≤ 25 °C with standard FR4 mounting. At elevated ambient temperatures, current must be derated per the 375 K/W per-device R_th(j-a) curve; at 100 °C ambient, max I_C drops to approximately −65 mA to maintain T_j ≤ 175 °C.

Does BC856BSHF support simultaneous conduction of both transistors without thermal interaction?

Yes-BC856BSHF features electrically isolated transistors with no mutual interference, and its per-device thermal resistance (R_th(j-a) = 375 K/W) is specified for simultaneous full-power operation. Thermal coupling is minimized by monolithic die layout and shared package mass, allowing concurrent −100 mA switching in both channels without exceeding 175 °C junction temperature on compliant PCBs.

Can BC856BSHF replace discrete BC856B transistors in existing SOT23 layouts?

No-BC856BSHF uses SOT363 (6-pin TSSOP), not SOT23. Its 0.65 mm pitch and 2.1 mm × 1.25 mm footprint are incompatible with SOT23 land patterns. A PCB redesign is required; however, it replaces two SOT23 BC856Bs with identical electrical specs and added matching benefits in half the board area.

What is the typical transition frequency (f_T) of BC856BSHF and its practical implication?

The BC856BSHF has f_T = 100 MHz at V_CE = −5 V, I_C = −10 mA. This supports stable small-signal amplification up to ~10–20 MHz and fast switching (t_f/t_r < 3 ns) in PWM-driven loads, making it suitable for audio preamps, ultrasonic driver bias, and sub-MHz digital signal routing-not RF or GHz applications.
