Product details
Overview
PUMH11-QX from Nexperia is a dual NPN resistor-equipped transistor (RET) in SOT363-3 (SC-88) package, rated for 50 V VCEO, 100 mA output current per transistor, with integrated 10 kΩ input bias resistors (R1 = R2 = 10 kΩ). It functions as a compact, AEC-Q101-qualified digital switching pair for low-current peripheral driving and IC input control in automotive body electronics.
For engineers reviewing the PUMH11-QX datasheet, PUMH11-QX pinout, PUMH11-QX application, or PUMH11-QX equivalent, this page delivers verified pin assignments, thermal derating curves, DC current gain (hFE ≥ 30 at IC = 5 mA), saturation voltage (VCE(sat) ≤ 150 mV), and off-state input threshold (VI(off) = 0.8–1.1 V) - all critical for logic-level interface design and BOM consolidation.
Technical Context
This device integrates two matched NPN transistors with on-chip base bias networks (R1 = R2 = 10 kΩ ±30%) to eliminate external resistors. Each transistor operates independently with open-base VCEO = 50 V and IO = 100 mA rating, supporting direct TTL/CMOS-compatible switching without level-shifting.
Thermal performance is defined for FR4 PCB mounting: per-device Ptot = 300 mW at Tamb = 25 °C, derating linearly above 25 °C with Rth(j-a) = 417 K/W. Junction temperature is limited to 150 °C, enabling operation across −65 °C to +150 °C ambient range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; defines safe switching headroom for 24 V automotive systems. |
| IO | 100 mA - Continuous output current per transistor; sufficient for LED drivers, small relays, and logic buffer loads. |
| R1 / R2 | 10 kΩ ±30% - Integrated base bias resistors reduce PCB area by ~2.5 mm² per channel vs discrete equivalents. |
| VCE(sat) | ≤150 mV @ IC = 10 mA, IB = 0.5 mA - Low saturation voltage minimizes power loss and self-heating in high-duty-cycle switching. |
| hFE | ≥30 @ VCE = 5 V, IC = 5 mA - Ensures reliable turn-on with standard microcontroller GPIO drive strength (e.g., 4 mA). |
| VI(off) | 0.8–1.1 V - Input voltage threshold below which both transistors remain fully off; enables noise-immune digital interfacing. |
| fT | 230 MHz - Transition frequency supports fast edge rates in signal routing and pulse-width modulation up to ~10 MHz. |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mount package: 1.35 mm × 2.2 mm footprint, 0.65 mm pitch, 1.1 mm max height, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1; common reference for first transistor's current path. |
| 2 | I1 | Base input for TR1; accepts logic-level signals directly without external pull-down. |
| 3 | O2 | Collector output for TR2; sinks load current when TR2 is active. |
| 4 | GND2 | Emiter connection for TR2; independent ground node enabling dual isolated switching paths. |
| 5 | I2 | Base input for TR2; electrically isolated from I1, allowing independent control of both transistors. |
| 6 | O1 | Collector output for TR1; provides second independent switched output with same ratings as O2. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Qualified for automotive applications including body control modules and lighting control units. |
| Dual NPN RET architecture | Two independent, resistor-equipped transistors in one 6-pin package reduces component count by 4 passive parts vs discrete solution. |
| Input voltage thresholds | VI(on) = 1.8–2.5 V and VI(off) = 0.8–1.1 V provide 0.7 V noise margin for robust 3.3 V logic interfacing. |
| Thermal derating curve | Per-device Ptot drops linearly from 300 mW at 25 °C to 0 mW at 100 °C, enabling predictable thermal design on FR4 PCBs. |
| Transition frequency | fT = 230 MHz allows clean switching of PWM signals up to 10 MHz without significant rise/fall time degradation. |
Applications
| Automotive Body Control Module | Industrial Sensor Interface Board |
|---|---|

IC Role / Device Role / Timing Role: Safe, transient-resistant enable switch for analog front-end power rails. Use Value: Built-in 10 kΩ bias resistors prevent floating inputs during reset, eliminating latch-up risk in safety-critical paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PUMD3-Q | NPN/PNP complementary pair; VCEO = 50 V, IO = 100 mA, same R1/R2 = 10 kΩ but opposite polarity per channel. | Required where push-pull or complementary switching (e.g., H-bridge half-bridge) is needed instead of dual low-side. | Select when driving bidirectional loads or requiring active pull-up capability not supported by PUMH11-QX's NPN-only topology. |
| PUMB11-Q | PNP/PNP dual RET; identical package and bias network (R1 = R2 = 10 kΩ), but emitter-connected outputs for high-side switching. | Used in high-side load switching (e.g., 12 V sensor supply enable) where sourcing current is required. | Choose for applications needing source-driven outputs; incompatible with low-side sink-only topologies without circuit redesign. |
Compared with PUMD3-Q and PUMB11-Q, PUMH11-QX provides dedicated dual NPN low-side switching with optimal VI(off)/VI(on) margins for 3.3 V logic, whereas alternatives require topology changes to support complementary or high-side operation.

FAQ
What is the maximum continuous junction temperature for PUMH11-QX?
The absolute maximum junction temperature (Tj) is 150 °C, as specified in the Limiting Values table. Operation beyond this temperature risks permanent parametric shift or failure. Derating begins at 25 °C ambient, with total device power dissipation dropping linearly to zero at 100 °C ambient per the published derating curve.
Can PUMH11-QX be used with 1.8 V logic inputs?
No - the minimum guaranteed VI(on) is 1.8 V (typical), but the device requires ≥2.5 V for reliable turn-on across temperature and process variation. At 1.8 V input, hFE degrades significantly and VCE(sat) rises above specification; use only with 3.3 V or 5 V logic families.
Is the R1/R2 ratio truly 1:1, and how tightly is it matched?
Yes - R2/R1 ratio is specified as 0.8–1.2 (±20%), with typical value of 1.0. This tight ratio ensures matched base drive conditions across both transistors, critical for balanced current sharing in parallel configurations and consistent timing in dual-switch applications.
Does PUMH11-QX support wave soldering, and what is the recommended footprint?
Yes - Nexperia provides validated wave soldering footprints for SOT363-3. The recommended layout uses 1.3 mm × 1.3 mm solder lands with 0.3 mm solder resist opening and 4.5 mm × 2.45 mm overall pad pattern, oriented with preferred transport direction aligned to pin 1 index mark.
