Nexperia USA Inc. PUMH13-QX

Overview

PUMH13-QX from Nexperia is an NPN/NPN double Resistor-Equipped Transistor (RET) in SOT363-3 (SC-88) package, featuring integrated bias resistors R1 = 4.7 kΩ and R2 = 47 kΩ, 50 V V_CEO, 100 mA output current per transistor, and AEC-Q101 qualification for automotive signal-level switching applications such as IC input control and low-current peripheral driving.

For engineers reviewing the PUMH13-QX datasheet, PUMH13-QX pinout, PUMH13-QX application, or PUMH13-QX equivalent, this device serves as a space- and BOM-optimized replacement for discrete transistor + resistor combinations in digital logic interfacing, level translation, and automotive body electronics where simplified layout and production reliability are critical.

Technical Context

The PUMH13-QX integrates two matched NPN transistors with dedicated on-chip base bias networks-R1 (input resistor) and R2 (feedback resistor)-enabling direct TTL/CMOS-compatible drive without external components. Each transistor operates independently with open-base V_CEO = 50 V and I_O = 100 mA rating.

Its dual-transistor topology supports push-pull or cascaded switching configurations; built-in resistor ratio R2/R1 = 10 ±2 ensures stable DC biasing across temperature (−40 °C to +150 °C), while VI(on) = 0.9–1.3 V and VI(off) = 0.5–0.6 V define robust logic-level compatibility.

FAQ

What is the maximum allowable ambient temperature for continuous 100 mA operation per channel?

The PUMH13-QX supports continuous 100 mA per transistor up to 75 °C ambient temperature when mounted on a standard FR4 PCB with single-sided 35 μm copper. Above this, power must be derated per the 417 K/W thermal resistance curve-e.g., at 100 °C ambient, max I_O drops to ~65 mA to maintain T_j ≤ 150 °C.

Can PUMH13-QX be used in high-speed switching applications above 1 MHz?

Yes-the built-in transistors exhibit f_T = 230 MHz at I_C = 10 mA, supporting clean switching up to ~10 MHz with proper layout. However, its primary design focus is digital logic interfacing rather than RF; for >50 MHz operation, discrete transistors with lower C_c (<1 pF) are recommended.

Is the R1/R2 ratio guaranteed over temperature and process variation?

Yes-the R2/R1 ratio is trimmed and tested per unit, specified as 8–12 (typical 10) across −40 °C to +150 °C. This tight ratio tolerance ensures stable DC biasing and consistent h_FE compensation even under thermal stress, unlike discrete resistor combinations subject to mismatched TC.

Does PUMH13-QX include ESD protection on its input pins?

No-PUMH13-QX has no integrated ESD protection diodes. Its I/O pins meet HBM ±2 kV per AEC-Q101, but external TVS or series resistors are required for environments with >8 kV contact discharge risk, such as automotive assembly lines or industrial field wiring.
