Nexperia USA Inc. NHUMB9X

Overview

NHUMB9X from Nexperia is a PNP/PNP resistor-equipped double transistor (RET) in SOT363 (SC-88) package, designed for digital switching and IC input control. It features 80 V collector-emitter breakdown voltage, −100 mA output current per transistor, built-in bias resistors (R1 = 10 kΩ, R2 = 47 kΩ), and AEC-Q101 qualification for automotive-grade reliability.

For engineers reviewing the NHUMB9X datasheet, NHUMB9X pinout, NHUMB9X application, or NHUMB9X equivalent, this device serves as a space- and cost-optimized alternative to discrete BC856-based dual-transistor configurations in low-power logic interface and load-switching circuits.

Technical Context

This dual PNP RET integrates two matched PNP transistors with monolithically embedded base bias resistors-R1 (10 kΩ) connected between base and emitter, and R2 (47 kΩ) between base and input-enabling direct TTL/CMOS-level drive without external components. The configuration supports independent transistor operation with shared ground terminals.

Each transistor delivers −80 V V_CEO, −100 mA I_O, and exhibits V_CE(sat) ≤ −100 mV at I_C = −10 mA / I_B = −0.5 mA. Thermal resistance is 358 K/W (per device, junction-to-ambient on FR4 PCB), supporting stable operation up to 150 °C junction temperature.

FAQ

What is the maximum operating temperature for NHUMB9X?

The NHUMB9X has a maximum junction temperature (T_j) of 150 °C and an ambient operating range of −55 °C to +150 °C. Its thermal resistance (R_th(j-a)) is 358 K/W per device on FR4 PCB, meaning it dissipates 350 mW at 25 °C ambient before reaching T_j = 150 °C. Derating is required above 25 °C per Fig. 1 in the datasheet.

Can NHUMB9X replace BC856-based circuits without redesign?

Yes-NHUMB9X directly replaces two BC856 transistors plus four external bias resistors in digital switching applications. Its pinout maps independently controllable inputs (I1/I2) and outputs (O1/O2), and its built-in 10 kΩ/47 kΩ resistor network matches typical BC856 base-drive requirements. No schematic or layout changes are needed beyond footprint adaptation to SOT363.

Is NHUMB9X pin-compatible with other NHUMBxx variants?

Yes-NHUMB9, NHUMB10, and NHUMB13 share identical SOT363 pinout, marking format (6A%/6B%/6D%), and electrical interface. Only R1 differs (10 kΩ / 2.2 kΩ / 4.7 kΩ); all retain R2 = 47 kΩ and identical V_CEO, I_O, and AEC-Q101 qualification. Swapping requires only verification of input voltage thresholds (VI(on)/VI(off)) for the target logic family.

Does NHUMB9X support 1.8 V logic-level drive?

No-NHUMB9X requires minimum VI(on) of −1.22 V (typ.) at I_C = −10 mA, making it unsuitable for direct 1.8 V GPIO drive. It is optimized for 3.3 V and 5 V systems. For 1.8 V compatibility, consider NHUMB10 (VI(on) = −0.81 V typ.) or NHUMB13 (−0.95 V typ.), which offer lower base turn-on thresholds due to smaller R1 values.
