Nexperia USA Inc. PUMB10F

Overview

PUMB10 from Nexperia is a PNP/PNP resistor-equipped double transistor (RET) in SOT363 (SC-88) package, rated for −50 V V_CEO, −100 mA output current per transistor, with built-in bias resistors R1 = 2.2 kΩ and R2 = 47 kΩ. It functions as a dual digital switch in low-power logic interface and peripheral driver circuits, commonly used in automotive body control modules and industrial I/O expanders.

For engineers reviewing the PUMB10 datasheet, PUMB10 pinout, PUMB10 application, or PUMB10 equivalent, key selection criteria include its AEC-Q101 qualification, integrated R1/R2 bias network enabling single-resistor drive, −100 mV V_CE(sat) at −5 mA/−0.25 mA, and thermal resistance of 417 K/W (per device on FR4).

Technical Context

The PUMB10 integrates two matched PNP transistors with monolithically embedded base bias resistors-R1 (2.2 kΩ) connected between input and base, R2 (47 kΩ) between base and emitter-forming a self-biased configuration that eliminates external bias components. Each transistor operates independently with open-base V_CEO = −50 V and I_O = −100 mA rating.

Its dual-transistor topology supports cascaded or parallel switching: Pin 1/GND1 and Pin 4/GND2 serve as separate emitter returns, while Pins 2/I1 and 5/I2 are isolated base inputs, and Pins 6/O1 and 3/O2 are independent collector outputs. The device is characterized for operation from −40 °C to +150 °C junction temperature and qualified per AEC-Q101.

FAQ

What is the maximum operating temperature for PUMB10?

The PUMB10 has a maximum junction temperature (T_j) of 150 °C and an ambient temperature range of −65 °C to +150 °C. Its thermal resistance is 417 K/W (per device on FR4 PCB), allowing continuous −100 mA operation up to +85 °C ambient when properly mounted with standard footprint and soldering.

Can PUMB10 replace discrete PNP transistors in existing designs?

Yes-PUMB10 directly replaces two discrete PNP transistors plus four external bias resistors. Its pinout matches standard dual-transistor layouts, and the integrated R1/R2 network (2.2 kΩ / 47 kΩ) provides identical biasing behavior to typical discrete configurations using 2.2 kΩ base resistors and 47 kΩ base-emitter resistors.

Is PUMB10 suitable for 3.3 V logic interfacing?

Yes-its VI(on) is −0.75 V typical at −5 mA collector current, ensuring reliable turn-on with 3.3 V CMOS outputs. The −0.6 V VI(off) threshold also guarantees full cutoff with 0 V logic low, eliminating need for pull-down resistors or level translators in standard microcontroller interfaces.

Does PUMB10 require derating at elevated temperatures?

Yes-its total power dissipation derates linearly above 25 °C ambient: 300 mW at 25 °C drops to 0 mW at 100 °C (based on 417 K/W R_th(j-a)). For continuous −100 mA operation, ambient must remain ≤ 65 °C; intermittent use allows higher ambient with pulse-width-limited duty cycle per Fig. 2 in the datasheet.
