Nexperia USA Inc. PUMD48-QZ

Overview

PUMD48-QZ from Nexperia is an NPN/PNP resistor-equipped double transistor (RET) in SOT363-3 (SC-88) package, integrating two bias-resistor-configured transistors: TR1 (NPN, R1 = 47 kΩ, R2 = 47 kΩ) and TR2 (PNP, R1 = 2.2 kΩ, R2 = 47 kΩ). It delivers 100 mA output current per transistor, supports ±50 V V_CEO, and is AEC-Q101 qualified for automotive signal-level switching and level translation.

For engineers reviewing the PUMD48-QZ datasheet, PUMD48-QZ pinout, PUMD48-QZ application, or PUMD48-QZ equivalent, this device serves as a space- and BOM-optimized replacement for discrete NPN+PNP pairs in digital control interfaces, low-current peripheral drivers, and IC input conditioning circuits where built-in biasing simplifies layout and reduces assembly cost.

Technical Context

This dual RET integrates complementary NPN and PNP transistors with factory-trimmed on-chip bias resistors-TR1 features R1 = 47 kΩ and R2/R1 ≈ 1.0, while TR2 uses R1 = 2.2 kΩ and R2/R1 ≈ 21-enabling direct logic-level drive without external base resistors. Both transistors share independent inputs and outputs, supporting push-pull or complementary switching topologies.

It operates across –40 °C to +150 °C junction temperature, with V_CE(sat) ≤ 100 mV (NPN) and ≤ –100 mV (PNP) at rated currents, and exhibits f_T of 230 MHz (NPN) and 180 MHz (PNP), confirming suitability for high-speed digital interface applications up to ~10 MHz switching.

FAQ

What is the maximum operating temperature for PUMD48-QZ?

The PUMD48-QZ has a maximum junction temperature (T_j) of 150 °C and operates over an ambient temperature range of –65 °C to +150 °C. Its thermal resistance R_th(j-a) is 417 K/W (per device on FR4 PCB), enabling reliable operation in under-hood automotive environments when mounted per recommended footprint.

Can PUMD48-QZ drive a 5 V relay coil directly?

Yes-each transistor supports up to 100 mA continuous output current and 50 V V_CEO. A typical 5 V relay coil drawing ≤80 mA can be driven directly by either O1 (NPN, sourcing via collector) or O2 (PNP, sinking via collector), provided the input voltage meets V_I(on) thresholds (1.6–3.0 V for TR1, –0.75 to –1.1 V for TR2).

How does the R2/R1 ratio affect switching behavior?

The R2/R1 ratio determines base current division and saturation depth: TR1's ratio of 0.8–1.2 ensures strong saturation with low input current, while TR2's ratio of 17–26 provides high base current gain for efficient PNP turn-on despite lower h_FE at negative V_CE. This asymmetry optimizes both transistors for logic-driven switching rather than analog amplification.

Is PUMD48-QZ pin-compatible with earlier PUMD48 variants?

Yes-PUMD48-QZ uses the same SOT363-3 (TSSOP6) package and identical pinout as PUMD48-Q. The "Z" suffix denotes tape-and-reel packaging per EIA-481; electrical characteristics, marking ("4%8"), and thermal performance remain unchanged from the qualified AEC-Q101 baseline.
