Nexperia USA Inc. NHUMB13X

Overview

NHUMB13X from Nexperia is a PNP/PNP resistor-equipped double transistor (RET) in SOT363 (SC-88) package, rated for −80 V V_CEO, −100 mA output current per transistor, with built-in bias resistors R₁ = 4.7 kΩ and R₂ = 47 kΩ. It functions as a dual high-voltage digital switch for level translation and IC input control in space-constrained automotive and industrial logic interfaces.

For engineers reviewing the NHUMB13X datasheet, NHUMB13X pinout, NHUMB13X application, or NHUMB13X equivalent, this device serves as an AEC-Q101-qualified drop-in alternative to discrete PNP pairs in load switching, bus interface buffering, and microcontroller GPIO expansion circuits where reduced BOM count and thermal efficiency are critical.

Technical Context

This dual PNP RET integrates two matched PNP transistors with dedicated base-emitter bias networks-R₁ sets input threshold voltage (VI(on) = −1.4 V typ. at I_C = −10 mA), while R₂/R₁ = 10 defines current gain stability under varying temperature (−40 °C to +150 °C junction). Each transistor operates independently with isolated emitters (GND1/GND2), enabling dual-channel sinking without shared emitter crosstalk.

The device uses epitaxial planar die construction with optimized doping profiles to achieve −80 V collector-base breakdown (V_CBO) and low −100 mV V_CE(sat) at I_C/I_B = 20, supporting reliable switching in 5 V–24 V logic-controlled loads. Thermal resistance from junction to ambient is 358 K/W per device on FR4 PCB, enabling sustained 100 mA operation within 150 °C T_j limit.

FAQ

What is the maximum continuous current per channel for NHUMB13X?

NHUMB13X supports −100 mA DC output current per transistor under Tamb ≤ 25 °C with derating to zero at 150 °C junction temperature. At 85 °C ambient, maximum continuous current is −72 mA per channel based on the 358 K/W per-device thermal resistance and 235 mW per-transistor power limit.

Can NHUMB13X replace BC856BS in existing designs?

Yes-NHUMB13X is a direct functional replacement for BC856BS in digital switching applications, offering identical SOT363 pinout, −80 V V_CEO, and −100 mA I_O. Its integrated 4.7 kΩ/47 kΩ bias network eliminates two external resistors per channel, simplifying layout and improving consistency over temperature versus discrete implementations.

Is the GND1 and GND2 pin electrically isolated internally?

Yes-GND1 and GND2 are physically separate emitter terminals with no internal connection. This isolation allows independent grounding of each transistor channel, preventing current-loop interference in mixed-signal systems and enabling differential sensing configurations without external isolation components.

Does NHUMB13X require external decoupling capacitors for stable operation?

No external decoupling is required for basic switching operation due to its low 3 pF collector capacitance and absence of internal oscillation-prone feedback paths. However, a 100 nF ceramic capacitor placed near the V_CC return path (GND1/GND2) is recommended when driving inductive loads to suppress transient voltage spikes exceeding −80 V.
