Product details
Overview
PUMH9 from Nexperia is an NPN/NPN resistor-equipped double transistor (RET) in SOT363-3 (SC-88) package, rated for 50 V VCEO, 100 mA output current per transistor, with integrated bias resistors R1 = 10 kΩ and R2 = 47 kΩ. It functions as a dual digital switch for level translation and load control in compact automotive and industrial PCBs.
For engineers reviewing the PUMH9 datasheet, PUMH9 pinout, PUMH9 application, or PUMH9 equivalent, this device serves as a space- and BOM-optimized replacement for discrete BC847-based driver stages - particularly where input threshold control, dual-channel switching, and thermal efficiency on FR4 PCBs are critical selection criteria.
Technical Context
The PUMH9 integrates two matched NPN transistors with monolithically embedded base bias networks: R1 (input resistor) and R2 (feedback resistor), enabling direct logic-level drive without external components. Each channel operates independently with open-base VCEO = 50 V and IO = 100 mA rating.
Its internal resistor ratio R2/R1 = 4.7 (typ.) sets predictable DC gain and saturation behavior, while VI(on) = 0.8–1.4 V (at IC = 1 mA) and VI(off) = 0.5–0.7 V (at IC = 100 µA) support reliable TTL/CMOS interfacing across –40 °C to +150 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 24 V industrial bus and 12 V automotive supply rails with margin. |
| IO | 100 mA - Continuous output current per transistor; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 10 kΩ ±30% - Input bias resistor; sets base current for defined turn-on threshold with standard MCU GPIOs. |
| R2/R1 | 4.7 (typ.) - Feedback-to-input resistor ratio; stabilizes operating point and improves noise immunity vs. single-resistor biasing. |
| Ptot (per device) | 300 mW at Tamb ≤ 25 °C - Total power dissipation limit on FR4 PCB; enables thermal design without heatsinking in low-duty-cycle apps. |
| fT | 230 MHz (typ.) - Transition frequency at VCE = 5 V, IC = 10 mA; supports fast digital switching up to ~10 MHz edge rates. |
| hFE | 100 (min.) at VCE = 5 V, IC = 5 mA - Minimum DC current gain; ensures robust saturation under worst-case temperature and process variation. |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mounted package: 1.35 mm × 2.2 mm footprint, 0.65 mm pitch, 0.95 mm max height, designed for reflow soldering on FR4 PCBs with 35 µm copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter of TR1 - Common reference node for first transistor; must be tied to system ground or local return path. |
| 2 | I1 | Base input of TR1 - Driven directly by logic signal; internal R1 connects to this pin for current-limited base bias. |
| 3 | O2 | Collector of TR2 - Active-high switched output; sinks current when TR2 is saturated (I2 high). |
| 4 | GND2 | Emiter of TR2 - Independent ground return for second transistor; allows separate grounding or isolation if needed. |
| 5 | I2 | Base input of TR2 - Second logic-controlled input; shares same bias architecture as I1 but electrically isolated. |
| 6 | O1 | Collector of TR1 - First active-high switched output; complements O2 for dual-load or complementary drive schemes. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET architecture | Two independent, resistor-equipped transistors in one SOT363-3 package - eliminates four external resistors and reduces layout area by >60% vs. discrete BC847 pairs. |
| Controlled VI(on)/VI(off) | VI(on) = 0.8–1.4 V and VI(off) = 0.5–0.7 V enable clean switching with 3.3 V and 5 V logic families without additional level-shifting circuitry. |
| Thermal derating profile | Rth(j-a) = 417 K/W (per device) on FR4 - allows full 100 mA operation up to +70 °C ambient before power reduction is required. |
| Automotive-grade reliability | Rated for Tamb = –55 °C to +150 °C and Tj ≤ 150 °C - qualified for under-hood and motor-control modules per AEC-Q101 stress test requirements. |
| Standardized marking | Marked "H%9" (where % = site code) - enables traceability and automated optical inspection compatibility in high-volume SMT lines. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Output Stage |

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 designs requiring adjustable gain or non-standard bias points. | Select when fine-grained control over base current or thermal separation between transistors is required. |
| PUMD9 | NPN/PNP complement; identical package and resistor values but mixed polarity - not interchangeable pin-for-pin. | Used in push-pull or level-shifting configurations where sourcing and sinking capability is needed simultaneously. | Select only for complementary output topologies; not a drop-in replacement for PUMH9's dual-NPN function. |
Compared with BC847BPDW1T3G, PUMH9 reduces bill-of-materials and assembly cost by integrating biasing; compared with PUMD9, it provides matched dual-NPN behavior essential for parallel load control rather than complementary drive.

FAQ
What is the maximum safe operating voltage for PUMH9 in continuous DC mode?
The absolute maximum VCEO is 50 V per transistor with open base, verified per IEC 60134 limiting values. For reliable long-term operation, Nexperia recommends staying ≤ 40 V DC under steady-state conditions with adequate PCB copper pour to maintain junction temperature below 150 °C.
Can PUMH9 be used in linear amplifier configurations?
No - PUMH9 is optimized for digital switching, not linear amplification. Its built-in resistors fix the base bias point, and hFE is specified only at switching test conditions (e.g., VCE = 5 V, IC = 5 mA). Linear operation would cause unpredictable gain, thermal runaway, and potential violation of R1/R2 tolerance limits.
How does the R2/R1 ratio affect switching performance?
The R2/R1 = 4.7 (typ.) ratio provides negative feedback that stabilizes the operating point against temperature-induced hFE variation and improves noise margin. It lowers effective input impedance and reduces sensitivity to stray capacitance, resulting in faster, more consistent turn-off transitions compared to single-resistor biasing.
Is PUMH9 compliant with lead-free reflow profiles?
Yes - PUMH9 is qualified for standard Pb-free reflow per JEDEC J-STD-020 Rev E, with peak temperature up to 260 °C for ≤ 30 seconds. The SOT363-3 package outline and solder land pattern in Figures 12–13 of the datasheet are fully compatible with IPC-7351B Class B footprints.
