Product details
Overview
PUMH9 from Nexperia is a dual NPN resistor-equipped transistor (RET) in SOT363-3 (SC-88) package, integrating two matched NPN transistors with built-in bias resistors R1 = 10 kΩ and R2 = 47 kΩ. It delivers 100 mA per transistor, supports 50 V VCEO, and is used for digital switching, IC input control, and load driving in space-constrained automotive and industrial PCBs.
For engineers reviewing the PUMH9 datasheet, PUMH9 pinout, PUMH9 application, or PUMH9 equivalent, this page provides verified pin functions, thermal derating curves, DC current gain (hFE ≥ 100 at IC = 5 mA), saturation voltage (VCE(sat) ≤ 100 mV), and validated alternatives to BC847-based discrete solutions.
Technical Context
The PUMH9 integrates two independent NPN transistors on a single die, each with dedicated base biasing via internal R1–R2 networks. Its dual configuration enables compact push-pull or cascaded digital logic stages without external resistors.
Each transistor operates with VCEO = 50 V, IO = 100 mA, and exhibits hFE ≥ 100 at VCE = 5 V and IC = 5 mA. Thermal resistance is 417 K/W (per device, FR4 PCB), supporting stable operation up to Tj = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; defines safe switching range for 24 V industrial loads. |
| IO | 100 mA - Continuous output current per transistor; sufficient for driving LED indicators or small relays. |
| R1 | 10 kΩ ±30% - Input bias resistor; sets base current for predictable turn-on without external components. |
| R2/R1 ratio | 4.7 - Fixed feedback ratio enabling stable saturation and noise immunity in digital switching. |
| VCE(sat) | ≤100 mV at IC = 5 mA, IB = 0.25 mA - Low saturation voltage minimizes power loss in high-duty-cycle switching. |
| hFE | ≥100 at VCE = 5 V, IC = 5 mA - Ensures reliable current amplification with minimal drive requirements. |
| fT | 230 MHz - Transition frequency supports fast digital edge rates up to ~10–20 MHz switching. |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mounted package with 0.65 mm lead pitch, 2.2 mm × 1.35 mm body, and exposed pad-compatible footprint per Nexperia's Fig. 12 reflow soldering standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter of TR1 - Common reference node for first transistor; must be tied to system ground or low-side return path. |
| 2 | I1 | Base input of TR1 - Driven by logic-level signal; internal R1 limits base current automatically. |
| 3 | O2 | Collector of TR2 - Active-high output node; sinks current when TR2 is on. |
| 4 | GND2 | Emiter of TR2 - Independent ground reference for second transistor; allows isolated or split-ground configurations. |
| 5 | I2 | Base input of TR2 - Second logic-controlled input; electrically isolated from I1 but shares same bias topology. |
| 6 | O1 | Collector of TR1 - Primary active-low output; sources current through load to GND1 when saturated. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET architecture | Two fully independent NPN transistors with matched R1/R2 networks eliminate need for 4 external bias resistors. |
| 100 mA per transistor rating | Supports direct driving of optocouplers, small solenoids, or logic buffers without external current boosting. |
| Low VCE(sat) (≤100 mV) | Reduces conduction loss to <1 mW at 10 mA load, critical for battery-powered or thermally constrained designs. |
| Thermal resistance (417 K/W) | Enables 300 mW total device dissipation on standard FR4 PCB - sufficient for continuous 100 mA switching at ambient ≤85 °C. |
| Automotive-grade reliability | Qualified per AEC-Q200 stress tests; operating ambient range −55 °C to +150 °C supports under-hood and motor-control applications. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input Stage |
|---|---|
|
Use Scenario: Level-shifting and debouncing of mechanical switch inputs in door latch or seat position sensors. IC Role / Device Role / Timing Role: Dual-transistor RET acts as dual-channel signal conditioner - one channel filters bounce, the other provides inverted logic for redundancy. Use Value: Eliminates 8 passive components per channel versus discrete BC847 + resistor solution, reducing BOM count and PCB area by >40%. |
Use Scenario: Converting 24 V DC field signals to 3.3 V/5 V logic levels for microcontroller GPIO inputs. IC Role / Device Role / Timing Role: Each transistor serves as a high-side or low-side level translator with built-in pull-up/pull-down biasing. Use Value: Enables direct connection to 24 V sensors without external voltage dividers or protection diodes - simplifies layout and improves ESD robustness. |
| Smart Lighting Driver Interface | IoT Sensor Node Power Switching |
|
Use Scenario: Driving multiple LED strings in architectural lighting panels using PWM-modulated control lines. IC Role / Device Role / Timing Role: One transistor switches the LED anode (high-side), the other controls cathode current sensing (low-side) for closed-loop dimming. Use Value: Matched hFE and VCE(sat) across both transistors ensures consistent brightness and thermal behavior between channels. |
Use Scenario: Enabling/disabling peripheral sensors (e.g., temperature, humidity) during sleep cycles in battery-powered edge nodes. IC Role / Device Role / Timing Role: Dual RET functions as independent load switches - one controls sensor VCC, the other manages I2C pull-up enable. Use Value: Ultra-low leakage (<100 nA ICEO) prevents battery drain during deep-sleep mode; R1/R2 network ensures clean turn-off without floating bases. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-NPN switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BPDW1T3G | Discrete dual NPN in SOT-363; no built-in resistors - requires 4 external bias resistors. | Higher component count and layout complexity; better for precision bias tuning or variable gain needs. | Select when adjustable hFE or custom R1/R2 ratios are required; not drop-in compatible. |
| PUMB9 | PNP/PNP complement; identical package and bias resistor values (R1 = 10 kΩ, R2 = 47 kΩ), but opposite polarity. | Used where high-side sourcing or inverted logic is needed - e.g., driving P-channel MOSFET gates. | Choose for complementary switching topologies requiring matched thermal and electrical characteristics to PUMH9. |
Compared with BC847BPDW1T3G, PUMH9 reduces bill-of-materials and assembly cost by integrating biasing; compared with PUMB9, it provides NPN/NPN topology essential for low-side switching and sink-driven logic interfaces.

FAQ
What is the maximum junction temperature and how does it affect continuous operation?
The PUMH9 has a maximum junction temperature (Tj) of 150 °C. With a per-device thermal resistance of 417 K/W on FR4 PCB, continuous 100 mA operation is viable up to ~85 °C ambient if power dissipation remains below 300 mW. Derating above 25 °C ambient follows the curve in Figure 1 of the datasheet.
Can PUMH9 replace BC847-based circuits without layout changes?
Yes - PUMH9 uses the same SOT363-3 (TSSOP6) footprint as BC847BPDW1T3G and shares identical pinout (GND1/I1/O2/GND2/I2/O1). However, because PUMH9 integrates bias resistors, external base resistors must be removed from the PCB to avoid double-biasing and unintended turn-on.
How does the R2/R1 ratio impact switching performance?
The R2/R1 ratio of 4.7 sets the internal feedback factor that stabilizes base current during saturation. This ensures consistent VCE(sat) ≤ 100 mV across temperature and process variation, improving noise margin and reducing sensitivity to input voltage fluctuations compared to single-resistor biasing.
Is PUMH9 qualified for automotive applications?
PUMH9 is not AEC-Q100 qualified, but it is AEC-Q200 stress-tested and rated for −55 °C to +150 °C ambient operation. Nexperia explicitly states it is "non-automotive qualified" in legal disclaimers; use in safety-critical automotive systems requires customer validation and assumes full liability.
