Product details
Overview
PUMH15-QX from Nexperia is an NPN/NPN resistor-equipped double transistor (RET) in SOT363-3 (SC-88) package, featuring integrated 4.7 kΩ input bias resistors (R1 = R2 = 4.7 kΩ) per transistor, 50 V VCEO, 100 mA output current, and AEC-Q101 qualification for automotive signal switching and digital logic interfacing.
For engineers reviewing the PUMH15-QX datasheet, PUMH15-QX pinout, PUMH15-QX application, or PUMH15-QX equivalent, this device serves as a space-optimized, bias-resistor-integrated dual NPN switch for low-current peripheral drivers, IC input control, and replacement of discrete transistor pairs in automotive body electronics and industrial I/O modules.
Technical Context
This dual RET integrates two matched NPN transistors with identical on-chip base bias networks-each with R1 = 4.7 kΩ (input resistor) and R2 = 4.7 kΩ (base-emitter feedback resistor), yielding R2/R1 = 1.0 (typical). It operates with open-base VCEO = 50 V and supports DC current gain (hFE) ≥30 at IC = 10 mA, VCE = 5 V.
The device delivers VCE(sat) ≤ 150 mV at IC = 10 mA / IB = 0.5 mA and exhibits VI(on) = 1.9–2.5 V and VI(off) = 0.5–1.1 V, enabling robust TTL/CMOS-level compatible switching without external bias components.
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 / R2 | 4.7 kΩ / 4.7 kΩ - Integrated base bias resistors eliminate need for external pull-up/pull-down components. |
| hFE | ≥30 - Minimum DC current gain at IC = 10 mA; ensures reliable saturation under typical digital drive conditions. |
| VCE(sat) | ≤150 mV - Low saturation voltage reduces power loss and heat generation in switching applications. |
| AEC-Q101 | Qualified - Meets stress-test requirements for automotive discrete semiconductors; suitable for under-hood and cabin ECUs. |
Pinout & Package
Package: SOT363-3 (TSSOP6), ultra-small surface-mount plastic package with 0.65 mm lead pitch, 2.2 mm × 1.35 mm footprint, and FR4 PCB-compatible thermal performance (Rth(j-a) = 417 K/W per device).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for transistor TR1; common reference node for first channel. |
| 2 | I1 | Base input for TR1; internally connected to R1 (4.7 kΩ) and R2 (4.7 kΩ) network. |
| 3 | O2 | Collector output for TR2; active-high switching node for second channel. |
| 4 | GND2 | Emiter connection for transistor TR2; independent ground reference for second channel. |
| 5 | I2 | Base input for TR2; identical internal bias network as I1 (R1 = R2 = 4.7 kΩ). |
| 6 | O1 | Collector output for TR1; active-high switching node for first channel. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET architecture | Two fully independent, resistor-equipped NPN transistors in one SOT363-3 package-reduces board area by ~40% vs. discrete pair. |
| Integrated bias network | R1 = R2 = 4.7 kΩ per channel with ±23% tolerance (3.3–6.1 kΩ); eliminates 4 external resistors and associated layout complexity. |
| Automotive-grade reliability | AEC-Q101 qualified with Tj max = 150 °C and storage range −65 to +150 °C-supports engine control, lighting, and HVAC modules. |
| Low-power switching | VCE(sat) ≤ 150 mV at IC = 10 mA ensures <1.5 mW conduction loss per channel-critical for battery-powered nodes. |
Applications
| Automotive Door Module | Industrial PLC Input Stage |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BDW1T1G | Discrete dual NPN without integrated resistors; requires external 4.7 kΩ base resistors per channel. | Higher BOM count and layout area; lacks AEC-Q101 qualification out-of-box. | Select when design requires adjustable bias or higher hFE (min 200) at low IC. |
| EMH11T2R | NPN/PNP RET with asymmetric R1/R2 (10 kΩ/47 kΩ); different input threshold behavior (VI(on) ≈ 2.8 V). | Not suitable for symmetric TTL/CMOS drive; intended for mixed-logic interfacing (e.g., 5 V → 3.3 V level shift). | Select only when cross-voltage domain translation is required and dual-NPN topology is not mandatory. |
Compared with BC847BDW1T1G, PUMH15-QX reduces component count by four resistors and guarantees automotive qualification; versus EMH11T2R, it provides matched dual-NPN behavior and tighter VI(on)/VI(off) symmetry for single-rail digital control.

FAQ
Is PUMH15-QX pin-compatible with other SOT363-3 dual transistors?
No-PUMH15-QX has a unique pin assignment (GND1-I1-O2-GND2-I2-O1) optimized for independent dual-channel operation. Unlike generic dual NPNs such as MMBT5401DW, its pinout places both emitters on outer pins (1 and 4) and cross-coupled outputs (O1 on pin 6, O2 on pin 3), preventing drop-in replacement without PCB redesign.
What is the maximum operating temperature for continuous use?
The absolute maximum junction temperature is 150 °C, and the device is rated for continuous ambient operation up to +150 °C when mounted on FR4 PCB with standard footprint. Derating begins above 25 °C ambient: total device power dissipation drops linearly from 300 mW at 25 °C to 0 mW at 175 °C per the published derating curve.
Can PUMH15-QX drive a 5 V relay coil directly?
Yes-each channel supports 100 mA output current and 50 V VCEO, exceeding typical 5 V relay coil requirements (e.g., 70 mA, 250 Ω). With VCE(sat) ≤ 150 mV, power dissipation remains below 11 mW per channel, well within the 300 mW per-device limit, provided PCB copper area meets Nexperia's FR4 reference layout.
Does the R2/R1 ratio affect switching thresholds in practice?
Yes-the nominal R2/R1 = 1.0 ratio sets VI(on) = 1.9–2.5 V and VI(off) = 0.5–1.1 V, creating a ~1.4 V hysteresis window that improves noise immunity in noisy automotive environments. This behavior is verified across −40 °C to +100 °C per Figures 5 and 6 in the datasheet, with minimal drift over temperature.
