Product details
Overview
PUMH14-QX from Nexperia is a dual NPN resistor-equipped transistor (RET) in SOT363 (SC-88) package, integrating two independent NPN transistors each with a 47 kΩ input bias resistor (R1) and open R2. It supports 50 V VCEO, 100 mA output current per transistor, and operates across −65 °C to +150 °C ambient range. Used for low-current digital signal interfacing in automotive control modules.
For engineers reviewing the PUMH14-QX datasheet, PUMH14-QX pinout, PUMH14-QX application, or PUMH14-QX equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating curves, and validated dual-transistor switching behavior in compact SMT packaging.
Technical Context
This device integrates two discrete NPN transistors on a single die, each with a precision 47 kΩ (±22%) built-in base bias resistor (R1) and no second resistor (R2 = open). It eliminates external bias networks for digital logic-level drive applications.
Each transistor exhibits VCEO = 50 V, IO = 100 mA, hFE ≥ 100 at IC = 1 mA, and VCE(sat) ≤ 150 mV at IC/IB = 20. Thermal resistance is 416 K/W per device on FR4 PCB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with margin. |
| IO | 100 mA - Continuous output current per transistor; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 47 kΩ (33–61 kΩ) - Integrated base bias resistor; reduces external component count and layout area by ~2 resistors per channel. |
| Ptot (per device) | 300 mW - Total power dissipation limit at Tamb ≤ 25 °C on FR4 PCB; defines thermal headroom for dual-channel operation. |
| hFE | ≥100 - DC current gain at VCE = 5 V, IC = 1 mA; ensures reliable saturation with standard microcontroller GPIO drive. |
| VCE(sat) | ≤150 mV - Collector-emitter saturation voltage at IC = 10 mA, IB = 0.5 mA; minimizes conduction loss in switching mode. |
Pinout & Package
SOT363 (TSSOP6) plastic surface-mount package: 6-pin, 0.65 mm pitch, 2.1 mm × 1.25 mm × 0.95 mm body. RoHS-compliant, qualified per AEC-Q101.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emitter connection for TR1; common reference node for first transistor channel. |
| 2 | I1 | Base input for TR1; internally connected to 47 kΩ resistor R1; accepts TTL/CMOS logic levels. |
| 3 | O2 | Collector output for TR2; active-high sink/source node for second channel load interface. |
| 4 | GND2 | Emitter connection for TR2; electrically isolated from GND1; enables dual independent ground-referenced outputs. |
| 5 | I2 | Base input for TR2; internally connected to 47 kΩ resistor R1; functionally identical to I1 but isolated. |
| 6 | O1 | Collector output for TR1; complements O2 for dual-channel digital switching without shared emitter constraints. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent NPN RETs | Two fully isolated transistor channels with dedicated emitters (GND1/GND2), enabling separate load referencing and noise isolation. |
| Integrated 47 kΩ bias resistors | Eliminates need for two external base resistors per channel, reducing BOM count by 4 components and PCB footprint by ≥1.5 mm². |
| AEC-Q101 qualification | Validated for automotive underhood and cabin applications including body control modules, lighting drivers, and sensor interface circuits. |
| Low VCE(sat) (≤150 mV) | Reduces power loss and self-heating during sustained switching, supporting 100% duty cycle operation within thermal limits. |
Applications
| Automotive Door Module Driver | Industrial PLC Input Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN RET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSVD2101PT3G | Single-channel NPN RET; R1 = 100 kΩ; no dual-emitter isolation; SOT-23 package. | Lacks independent GND1/GND2; unsuitable for isolated load referencing or differential sensing. | Select only when space-constrained single-channel switching is required and channel crosstalk is acceptable. |
| EMH11T2R | Dual NPN RET with R1 = 22 kΩ, R2 = 22 kΩ; higher base current drive; same SOT363 footprint. | Lower input impedance may overload weak MCU outputs; not optimized for 3.3 V logic drive. | Prefer when higher-speed switching (>1 MHz) is needed and 5 V logic interfaces dominate the design. |
Compared with NSVD2101PT3G and EMH11T2R, PUMH14-QX uniquely combines dual-channel independence, 47 kΩ bias optimization for 3.3 V/5 V logic compatibility, and AEC-Q101 qualification-making it optimal for automotive and safety-critical dual-signal routing.

FAQ
Is PUMH14-QX pin-compatible with other SOT363 dual-transistor packages?
No-PUMH14-QX uses a unique pin assignment: Pin 1 = GND1, Pin 2 = I1, Pin 3 = O2, Pin 4 = GND2, Pin 5 = I2, Pin 6 = O1. This differs from standard dual-NPN SOT363 variants like PBSS4041T, which assign collectors to Pins 1 and 2. Direct substitution requires PCB layout revision.
What is the maximum operating frequency for switching applications?
While not explicitly specified in the datasheet, typical fT for comparable Nexperia RETs is ~100 MHz. At IC = 10 mA, the measured Cc is 2.5 pF, supporting clean edge transitions up to ~5 MHz in buffered digital switching-verified via Fig. 3 and Fig. 4 transient response curves.
Can PUMH14-QX drive a 10 mA LED directly from a 3.3 V MCU GPIO?
Yes-each channel draws ~55 µA base current at 3.3 V (calculated from R1 = 47 kΩ), well within typical MCU GPIO sink capability (≥20 mA). With hFE ≥ 100, it supports ≥5.5 mA collector current; for 10 mA, add a series current-limiting resistor (e.g., 220 Ω) at the collector.
Does the "R2 = open" specification mean the second resistor is omitted or unconnected?
"R2 = open" means no internal resistor connects between base and emitter-only R1 (47 kΩ) is integrated. This configuration matches standard single-bias RET topology, enabling standard digital switching without emitter feedback or Schmitt-trigger behavior.
