Nexperia USA Inc. PUMD2-QZ

Overview

PUMD2-QZ from Nexperia is a resistor-equipped double transistor (RET) integrating one NPN and one PNP silicon bipolar transistor with built-in bias resistors (R1 = 22 kΩ, R2 = 22 kΩ) in a single SOT363-3 (SC-88/TSSOP6) package. It delivers 100 mA output current per transistor, supports ±50 V collector-emitter voltage, and is AEC-Q101 qualified for automotive signal-level switching and level translation.

For engineers reviewing the PUMD2-QZ datasheet, PUMD2-QZ pinout, PUMD2-QZ application, or PUMD2-QZ equivalent, this device serves as a space- and BOM-optimized replacement for discrete NPN+PNP pairs in digital logic interfacing, low-current peripheral control, and bidirectional I/O conditioning where simplified biasing and reduced pick-and-place count are critical.

Technical Context

This dual-transistor configuration enables complementary switching without external base resistors: TR1 (NPN) operates with input at Pin 2 (I1), output at Pin 6 (O1); TR2 (PNP) uses input at Pin 5 (I2), output at Pin 3 (O2), both sharing independent emitter grounds (Pins 1 and 4). Each transistor features matched 22 kΩ input bias resistors and a 1:1 R2/R1 ratio, enabling predictable VI(on)/VI(off) thresholds across temperature.

The device exhibits distinct high-frequency behavior: TR1 (NPN) achieves 230 MHz fT at IC = 10 mA, while TR2 (PNP) delivers 180 MHz fT under symmetric negative-bias conditions. Thermal resistance is 417 K/W (per device, FR4 PCB), supporting continuous operation up to 150 °C junction temperature with 300 mW total power dissipation.

FAQ

What is the maximum operating temperature for PUMD2-QZ?

The absolute maximum junction temperature is 150 °C, and the ambient temperature range is −55 °C to +150 °C. Derated power dissipation begins at 25 °C ambient, with 300 mW total device power limit on FR4 PCB-requiring thermal relief pads or airflow above 85 °C ambient.

Can PUMD2-QZ replace discrete transistor-resistor combinations in existing designs?

Yes-its pin-compatible SOT363-3 footprint and integrated 22 kΩ bias resistors allow direct drop-in replacement for two discrete NPN+PNP transistors plus four resistors. Layout changes are limited to removing resistors and verifying ground separation between GND1 and GND2.

Does PUMD2-QZ support 1.8 V logic input levels?

Yes-VI(on) is 1.7 V typical and 2.5 V maximum for TR1 (NPN) at I_C = 5 mA, ensuring reliable turn-on from 1.8 V GPIOs. For TR2 (PNP), VI(on) is −1.7 V typical, compatible with inverted logic or open-drain drivers referenced to higher rails.

How does the R2/R1 ratio affect switching behavior?

The R2/R1 ratio of 1.0 ±0.2 sets the internal feedback path that stabilizes base current and improves noise immunity. This ratio ensures consistent VI(on)/VI(off) thresholds across temperature and process variation-critical for robust operation in noisy automotive environments.
