Product details
Overview
PUMH15 from Nexperia is a dual NPN resistor-equipped transistor (RET) in SOT363-3 (SC-88) package, integrating two matched 50 V, 100 mA NPN transistors with built-in 4.7 kΩ input bias resistors (R1 = R2 = 4.7 kΩ) and unity R2/R1 ratio. It functions as a compact, pre-biased logic-level switch pair for digital signal routing and low-current peripheral interfacing in space-constrained PCBs.
For engineers reviewing the PUMH15 datasheet, PUMH15 pinout, PUMH15 application, or PUMH15 equivalent, this device is selected for its reduced external component count, guaranteed DC current gain (hFE ≥ 30 at IC = 10 mA), low VCEsat (≤150 mV), and validated thermal performance on FR4 PCBs-key criteria when replacing discrete BJT + resistor combinations in I/O buffering and level-shifting circuits.
Technical Context
The PUMH15 integrates two independent NPN transistors, each with dedicated base biasing via internal R1 (4.7 kΩ) and R2 (4.7 kΩ) resistors, eliminating external base resistors. Its R2/R1 ratio of 1.0 ±0.2 ensures consistent saturation behavior across temperature (−40 °C to 150 °C).
Each transistor supports 50 V VCEO and 100 mA IO under continuous operation, with VI(on) = 1.9–2.5 V and VI(off) = 0.5–1.1 V at Tamb = 25 °C, enabling direct interface with 3.3 V and 5 V logic families without level translation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V industrial I/O and 3.3/5 V logic systems with margin. |
| IO | 100 mA - Continuous output current per transistor; sufficient for driving LEDs, small relays, and logic inputs. |
| R1 / R2 | 4.7 kΩ each - Integrated base bias resistors reduce bill-of-materials and eliminate layout sensitivity to stray capacitance. |
| hFE | ≥30 at IC = 10 mA - Guaranteed DC current gain ensures reliable saturation with standard microcontroller GPIO drive capability. |
| VCEsat | ≤150 mV at IC = 10 mA, IB = 0.5 mA - Low saturation voltage minimizes power loss and self-heating in switching applications. |
| fT | 230 MHz typical - High transition frequency supports clean switching up to ~10 MHz digital signals without waveform degradation. |
Pinout & Package
Package: SOT363-3 (SC-88), 6-pin TSSOP surface-mount plastic package with 0.65 mm pitch; dimensions 2.2 mm × 1.35 mm × 0.95 mm (L × W × H); FR4-compatible reflow footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1; common reference node for first transistor's current path. |
| 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 transistor stage. |
| 4 | GND2 | Emiter connection for TR2; isolated ground return for second transistor, enabling independent biasing. |
| 5 | I2 | Base input for TR2; identical internal resistor network as I1, supporting matched dual-channel operation. |
| 6 | O1 | Collector output for TR1; primary switching output paired with GND1 for first channel. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET architecture | Two fully independent, resistor-equipped NPN transistors in one SOT363-3 package-enables compact dual-channel logic buffering without cross-talk. |
| Built-in matched bias network | R1 = R2 = 4.7 kΩ ±28%, R2/R1 = 1.0 ±0.2 - eliminates manual resistor selection and matching, ensuring consistent turn-on thresholds across channels. |
| Low VCEsat and VI(on) | VCEsat ≤ 150 mV, VI(on) = 1.9–2.5 V - allows direct drive from 3.3 V MCU outputs while maintaining < 0.15 V drop at 10 mA load. |
| Thermal robustness | Rth(j-a) = 417 K/W (per device on FR4) - supports 300 mW total dissipation at 25 °C ambient, enabling sustained 100 mA switching without heatsinking. |
Applications
| LED Driver Interface | Microcontroller I/O Expander |
|---|---|
Use Scenario: Driving multiple status LEDs from a resource-constrained MCU with limited GPIO count and no external pull-up/pull-down support. IC Role / Device Role: Dual-channel low-side switch providing independent LED anode/cathode control with integrated current limiting via R1/R2. Use Value: Eliminates four external resistors and two discrete transistors; reduces PCB area by >60% versus discrete solution while maintaining 100 mA per LED. |
Use Scenario: Extending GPIO capability of an ARM Cortex-M0+ MCU to manage 8-bit parallel bus signals for sensor arrays or display modules. IC Role / Device Role: Logic-level translator and buffer between MCU I/O pins and higher-capacitance peripheral buses. Use Value: VI(on)/VI(off) specs ensure clean 3.3 V logic recognition; fT = 230 MHz prevents signal edge degradation at 10 MHz bus rates. |
| Industrial Sensor Signal Conditioning | USB-C Port Power Switch Control |
Use Scenario: Level-shifting and isolation of open-collector sensor outputs (e.g., proximity, limit switches) into 3.3 V microcontroller inputs. IC Role / Device Role: Active pull-up switch converting 0–24 V sensor signals to clean 0–3.3 V logic levels with ESD-tolerant inputs. Use Value: VEBO = 10 V and VI(off) ≤ 1.1 V enable safe clamping of 24 V transients; GND1/GND2 separation avoids ground-loop coupling. |
Use Scenario: Controlling VBUS enable/disable paths in USB-C receptacle designs requiring dual independent power switches for redundant sourcing. IC Role / Device Role: Dual low-side gate driver for two external N-channel MOSFETs managing separate VBUS paths. Use Value: Matched R1/R2 and hFE ≥ 30 guarantee simultaneous, synchronized turn-on of both MOSFETs with < 100 ns skew under 5 V control. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN RET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PUMD15 | Complementary NPN/PNP configuration; R1 = 4.7 kΩ, R2 = 4.7 kΩ; same VCEO (50 V), IO (100 mA), but PNP section has lower hFE (min 30 vs NPN's min 30) and higher |VEBO| (10 V). | Required where one channel must sink and the other source current (e.g., push-pull drivers); not suitable for dual-sink-only topologies. | Select PUMD15 only if mixed polarity switching is needed; otherwise PUMH15 offers superior channel matching and simpler bias design. |
| PUMB15 | PNP/PNP dual RET; identical package and resistor values, but PNP devices have VECO = −50 V, IO = −100 mA, and VI(on) ≈ −1.9 V - requires inverted logic drive. | Used in high-side switching or negative-rail interfaces; incompatible with standard positive-logic MCU outputs without inversion. | Choose PUMB15 only for negative-supply domains or high-side load control; PUMH15 remains optimal for conventional low-side 3.3/5 V digital interfacing. |
Compared with PUMD15 and PUMB15, the PUMH15 provides strictly matched NPN characteristics, simplified unipolar logic compatibility, and guaranteed hFE symmetry-making it the preferred choice for dual low-side switching where polarity uniformity and ease of integration outweigh the need for complementary or high-side functionality.

FAQ
What is the maximum continuous junction temperature for PUMH15?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in the Limiting Values table. Operation above this threshold risks permanent parametric shift or failure. Derating begins at Tamb > 25 °C, with per-device Ptot dropping linearly to 0 mW at 150 °C ambient when mounted on standard FR4 PCB.
Can PUMH15 be used with 1.8 V logic inputs?
No-VI(on) is specified as 1.9–2.5 V at IC = 20 mA, meaning reliable turn-on requires ≥1.9 V. At 1.8 V, hFE drops significantly and VCEsat increases beyond 150 mV, risking incomplete saturation. Use only with 3.3 V or 5 V logic families.
Is the R1/R2 ratio guaranteed over temperature?
Yes-the R2/R1 ratio is specified as 0.8–1.2 at Tamb = 25 °C, and characterization data (Fig. 5–6) shows VI(on)/VI(off) remain stable across −40 °C to 100 °C, confirming matched resistor TC behavior essential for dual-channel consistency.
Does PUMH15 require external decoupling capacitors?
No-its internal resistor network and low fT (230 MHz) make it inherently stable without external bypassing. However, a 100 nF ceramic capacitor near the VCC/GND pair of each channel is recommended for noise immunity in high-dI/dt switching environments.
