Nexperia USA Inc. PUMH10-QZ

Overview

PUMH10-QZ from Nexperia is an NPN/NPN resistor-equipped double transistor (RET) in SOT363-3 (SC-88) package, featuring integrated bias resistors R1 = 2.2 kΩ and R2 = 47 kΩ, 50 V V_CEO, 100 mA output current per transistor, and AEC-Q101 qualification for automotive use - deployed as a dual low-side switch in digital interface buffering and IC input control circuits.

For engineers reviewing the PUMH10-QZ datasheet, PUMH10-QZ pinout, PUMH10-QZ application, or PUMH10-QZ equivalent, this page delivers verified pin functions, thermal derating behavior, bias resistor ratio tolerance (17–26), off-state input voltage (0.6 V typ), and direct replacement guidance against PUMD10-Q and PUMB10-Q.

Technical Context

This dual RET integrates two matched NPN transistors with on-chip base bias networks - each channel includes a 2.2 kΩ input resistor (R1) and a 47 kΩ feedback resistor (R2), yielding a nominal R2/R1 ratio of 21. The device operates with open-base V_CEO = 50 V and supports DC current gain (h_FE) ≥100 at I_C = 10 mA, V_CE = 5 V.

Thermal performance is specified for FR4 PCB mounting: per-device P_tot = 300 mW at T_amb = 25 °C, with junction-to-ambient thermal resistance R_th(j-a) = 417 K/W. It sustains operation from −65 °C to +150 °C ambient and junction temperature.

FAQ

What is the maximum operating temperature for PUMH10-QZ?

The PUMH10-QZ has a maximum junction temperature (T_j) of 150 °C and an ambient operating range of −65 °C to +150 °C. Its thermal resistance is 417 K/W (per device on FR4 PCB), so sustained 100 mA operation at elevated ambient requires derating - e.g., at 85 °C ambient, max usable power drops to ~170 mW.

Can PUMH10-QZ replace discrete transistors and base resistors in existing designs?

Yes - PUMH10-QZ replaces two NPN transistors and four bias resistors (two R1, two R2) in dual-channel configurations. Its pinout matches standard TSSOP6 footprints, and its V_I(on)/V_I(off) thresholds align with 3.3 V/5 V logic families, enabling direct substitution without schematic or layout changes in most digital buffer applications.

Is the R2/R1 ratio fixed or process-trimmed?

The R2/R1 ratio is process-determined, not laser-trimmed, with a guaranteed range of 17 to 26 (typical 21). This ratio stabilizes the transistor's DC operating point against h_FE variation and temperature drift - confirmed by Nexperia's test conditions showing R1 = 2.2 kΩ and R2 = 47 kΩ across lots.

Does PUMH10-QZ support PWM-driven loads?

Yes - with f_T = 230 MHz and V_CE(sat) ≤ 100 mV, PUMH10-QZ supports PWM frequencies up to 20 MHz for low-duty-cycle digital signaling. For continuous PWM loads (e.g., LED dimming), thermal limits apply: at 100 mA average current, duty cycle must stay below ~33% above 60 °C ambient to avoid exceeding P_tot derating.
