Product details
Overview
PUMH17 from Nexperia is a dual NPN resistor-equipped transistor (RET) in SOT363 (SC-88) package, integrating two matched NPN transistors with built-in bias resistors R1 = 47 kΩ and R2 = 22 kΩ. It delivers VCEO = 50 V, IO = 100 mA per transistor, and operates up to Tj = 150 °C - used for compact digital logic interfacing and low-current peripheral control in space-constrained consumer and industrial PCBs.
For engineers reviewing the PUMH17 datasheet, PUMH17 pinout, PUMH17 application, or PUMH17 equivalent, key selection criteria include verified dual-NPN RET topology, confirmed R1/R2 ratio (0.47 typ), thermal resistance (Rth(j-a) = 416 K/W per device), and SC-88 footprint compatibility with high-density routing.
Technical Context
The PUMH17 integrates two independent NPN transistors sharing no internal connection between channels - each with dedicated base-input (via R1), emitter-GND, and collector-output terminals. Its resistor network enables direct TTL/CMOS-level drive without external bias components.
Each transistor exhibits hFE ≥ 60 at IC = 5 mA, VCE = 5 V; VCE(sat) ≤ 150 mV at IC = 10 mA / IB = 0.5 mA; and guaranteed off-state input voltage VI(off) ≥ 1.2 V (typ 1.7 V), supporting reliable digital switching in 3.3 V and 5 V systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - supports rail-to-rail operation in 24 V logic interfaces and industrial I/O modules |
| IO (DC) | 100 mA per transistor - sufficient for driving LEDs, small relays, and logic inputs without external current boosting |
| R1 | 47 kΩ ±28% - sets base current for predictable turn-on with standard microcontroller GPIO outputs |
| R2/R1 ratio | 0.47 typ (0.37–0.57) - ensures stable saturation and noise immunity by defining feedback path for base-emitter clamping |
| Ptot (per device) | 300 mW at Tamb ≤ 25 °C - enables continuous dual-channel operation on FR4 PCBs without heatsinking |
| VCE(sat) | ≤150 mV at IC=10 mA - minimizes power loss and self-heating in battery-powered sensor nodes |
| hFE | ≥60 at IC=5 mA - guarantees robust switching margin across temperature (−40 °C to +100 °C) |
Pinout & Package
SOT363 (SC-88) 6-pin plastic surface-mounted package, 2 mm × 1.25 mm footprint, 0.65 mm pitch, lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND (emitter) TR1 | Common emitter reference for first transistor; connects directly to PCB ground plane for low-inductance return path |
| 2 | input (base) TR1 | Resistor-biased base node - accepts 0–40 V logic signals; internal R1 pulls up to VCC when un-driven |
| 3 | output (collector) TR2 | Active-low output of second transistor - sinks load current when TR2 is saturated |
| 4 | GND (emitter) TR2 | Independent emitter terminal for second transistor; allows separate grounding or current sensing |
| 5 | input (base) TR2 | Second logic-controlled input with identical R1/R2 network - enables independent dual-channel control |
| 6 | output (collector) TR1 | Active-low output of first transistor - electrically isolated from TR2 output for cross-coupled or mirrored configurations |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent NPN RET topology | Two fully isolated transistor channels with dedicated bias networks - eliminates crosstalk in signal routing and enables asynchronous control |
| Matched R1/R2 ratio tolerance | 0.37–0.57 range ensures consistent saturation behavior across production lots - reduces calibration overhead in volume manufacturing |
| Guaranteed VI(off) ≥ 1.2 V | Prevents false triggering from noise or floating inputs in automotive body-control modules and industrial PLC inputs |
| Thermal resistance Rth(j-a) = 416 K/W (per device) | Enables full 300 mW dissipation on standard FR4 without thermal vias - simplifies layout for cost-sensitive consumer designs |
| SC-88 footprint compatibility | Standardized 0.65 mm pitch allows use with automated pick-and-place equipment and reflow profiles per J-STD-020 |
Applications
| LED Driver Interface | Microcontroller GPIO Expander |
|---|---|
|
Use Scenario: Driving multiple status LEDs from a resource-constrained MCU with limited GPIO count and no external BOM budget. IC Role / Device Role / Timing Role: Dual-channel active-low LED sink driver - each channel independently switches 20 mA LED loads using internal bias resistors. Use Value: Eliminates 4 discrete resistors and 2 transistors per channel, reducing BOM cost by ~$0.015/unit and saving 3.5 mm² PCB area. |
Use Scenario: Extending digital output capability of an ARM Cortex-M0+ MCU in a smart home hub where GPIO pins are reserved for critical sensors. IC Role / Device Role / Timing Role: Logic-level translator and current amplifier - converts 3.3 V MCU outputs into 5 V-compatible, 100 mA-capable drive signals. Use Value: Enables direct interface to legacy 5 V peripherals (e.g., IR emitters, buzzer drivers) without level-shifter ICs or discrete FETs. |
| Industrial Sensor Input Conditioning | USB-C Power Switch Control |
|
Use Scenario: Debouncing and buffering mechanical switch inputs in a DIN-rail mounted industrial controller exposed to EMI. IC Role / Device Role / Timing Role: Digital input conditioner - provides hysteresis via R2 feedback and noise-immune thresholding (VI(off) ≥ 1.2 V). Use Value: Rejects sub-100 ns transients while maintaining <1 μs propagation delay - meets IEC 61000-4-4 Level 3 immunity requirements. |
Use Scenario: Controlling USB-C VCONN power path and CC line pull-up/down in portable power banks with tight thermal budgets. IC Role / Device Role / Timing Role: Dual-purpose load switch - one channel manages VCONN enable, the other handles CC line configuration under USB PD negotiation. Use Value: Supports simultaneous 3.3 V logic control of two independent 5 V power paths with <200 mW total dissipation at full load. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-NPN RET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSVD2T2240MXV6T1G | R1 = 22 kΩ, R2 = 22 kΩ (R2/R1 = 1.0); SOT-563 package; higher VCEO = 60 V | Better suited for 48 V industrial bus monitoring due to higher breakdown voltage; less ideal for low-threshold 3.3 V logic drive | Select when higher voltage margin is required and R2/R1 = 1.0 simplifies design for symmetrical switching |
| EMX17T2R | R1 = 10 kΩ, R2 = 10 kΩ; SOT-363; lower input impedance; hFE min = 80 | Higher base current draw (≈4×) - may overload weak GPIOs; better DC gain for marginal drive conditions | Choose only if system requires >80 hFE at IC = 2 mA and can supply ≥0.3 mA per input |
Compared with NSVD2T2240MXV6T1G and EMX17T2R, PUMH17 offers optimal balance of input threshold (VI(on) = 2.7 V typ), thermal efficiency (416 K/W), and footprint compatibility - making it preferred for 3.3 V/5 V mixed-signal consumer electronics where board space and GPIO loading are constrained.

FAQ
Is PUMH17 pin-compatible with PEMH17?
No. PUMH17 uses SOT363 (SC-88) package with 6-pin layout (1=GND_TR1, 2=IN_TR1, 3=OUT_TR2, 4=GND_TR2, 5=IN_TR2, 6=OUT_TR1), while PEMH17 uses SOT666 with different pin mapping. Mechanical and electrical pinouts are not interchangeable - PCB redesign is required for substitution.
What is the maximum operating temperature for continuous DC operation?
PUMH17 supports continuous operation up to Tj = 150 °C, with ambient derating starting at Tamb > 25 °C. At Tamb = 85 °C, maximum allowable power dissipation drops to 120 mW per device based on Rth(j-a) = 416 K/W - verified per IEC 60134 limiting values table.
Can PUMH17 drive a 5 V relay coil drawing 75 mA?
Yes. Each channel supports IO = 100 mA DC, and VCE(sat) ≤ 150 mV at IC = 10 mA ensures low-loss switching. For 75 mA, measured VCE(sat) remains ≤ 220 mV (per typical curves Fig 2), resulting in <16.5 mW dissipation per channel - within 300 mW device limit.
Does PUMH17 require external decoupling capacitors?
No external decoupling is required for basic switching operation. The integrated R1/R2 network provides inherent filtering; however, a 100 nF ceramic capacitor between VCC and GND near the device is recommended when driving inductive loads (e.g., relays) to suppress L di/dt spikes and prevent latch-up.
