Product details
Overview
PUMH7H-QF from Nexperia is an NPN/NPN resistor-equipped double transistor (RET) in SOT363 (SC-88) package, rated for 50 V VCEO, 100 mA output current per transistor, with built-in 4.7 kΩ base bias resistor (R1) and open R2. It serves as a dual digital switch in automotive-grade signal conditioning and load control circuits, replacing discrete BC847 pairs in space-constrained PCBs.
For engineers reviewing the PUMH7H-QF datasheet, PUMH7H-QF pinout, PUMH7H-QF application, or PUMH7H-QF equivalent, this page delivers verified electrical specs, thermal derating curves, AEC-Q101 qualification status, and validated alternatives for automotive and industrial switching designs requiring reduced component count and high-temperature operation up to 175 °C.
Technical Context
This dual RET integrates two matched NPN transistors with individual emitter-grounded configurations and dedicated base resistors-only R1 (4.7 kΩ, ±28%) is populated; R2 is unconnected. Each transistor operates independently with open-base VCEO = 50 V and IO = 100 mA rating, enabling parallel or cascaded switching without external bias networks.
Thermal design is supported by per-device Rth(j-a) = 417 K/W on FR4 PCB and junction temperature tolerance up to 175 °C, meeting AEC-Q101 stress test requirements for under-hood automotive modules and industrial motor drivers where ambient temperatures exceed 125 °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 and 48 V automotive loads. |
| IO | 100 mA - Continuous output current per transistor; supports driving LEDs, small relays, or logic inputs without external current limiting. |
| R1 | 4.7 kΩ (3.3–6.1 kΩ) - Integrated base bias resistor enables direct microcontroller GPIO connection without discrete pull-up or current-limiting resistors. |
| Tj max | 175 °C - Junction temperature limit; allows operation in engine control units and power inverters with minimal heatsinking. |
| Ptot (per device) | 360 mW at Tamb ≤ 25 °C - Total dissipation budget for both transistors; derates linearly to zero at 175 °C ambient per Fig. 1. |
| hFE | 200 min at IC = 1 mA - DC current gain ensures reliable saturation with low base drive, reducing MCU I/O loading. |
| VCE(sat) | 100 mV max at IC = 10 mA, IB = 0.5 mA - Low saturation voltage minimizes conduction loss and self-heating during sustained switching. |
Pinout & Package
SOT363 (TSSOP6) plastic surface-mount package: 6-pin, 0.65 mm pitch, 2.1 mm × 1.25 mm × 0.95 mm body height. Moisture sensitivity level (MSL) 1, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1; common reference for first transistor's current path. |
| 2 | I1 | Base input for TR1; driven through internal R1 (4.7 kΩ) from external signal source. |
| 3 | O2 | Collector output of TR2; active-high switching node for second load. |
| 4 | GND2 | Emiter connection for TR2; independent ground return for second transistor. |
| 5 | I2 | Base input for TR2; no internal resistor (R2 = open), requires external bias if used. |
| 6 | O1 | Collector output of TR1; primary switching node with integrated R1 bias network. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET architecture | Two independent NPN transistors in one SOT363 footprint, eliminating four discrete passives and reducing layout area by >60% vs. BC847 pair. |
| Integrated R1 bias resistor | 4.7 kΩ ±28% on TR1 base enables direct 3.3 V/5 V GPIO interfacing without external components, lowering BOM cost and assembly steps. |
| AEC-Q101 qualified | Stress-tested per Automotive Electronics Council standard for discrete semiconductors, supporting deployment in engine management, body control, and ADAS modules. |
| High-temperature operation | Rated for continuous operation at Tamb = 175 °C with full parameter performance, enabling placement near power stages without thermal derating penalties. |
| Low VCE(sat) | ≤100 mV at 10 mA collector current ensures <1 mW conduction loss per transistor, critical for battery-powered and energy-efficient systems. |
Applications
| Automotive Body Control Module | Industrial PLC Input Conditioning |
|---|---|
Use Scenario: Switching interior lighting, door lock actuators, and HVAC fan controls in 12 V/24 V vehicle subsystems. IC Role / Device Role / Timing Role: Dual low-side switch providing isolated load control with single-GPIO activation per channel.

IC Role / Device Role / Timing Role: High-side or low-side PWM switch controlling motor direction and speed via MCU-generated pulses. Use Value: 100 mA per channel supports 5 W motor loads at 50 V, while 175 °C Tj rating permits mounting directly on motor driver heat sinks. | Use Scenario: Regulating cooling fans in portable ultrasound and patient monitor enclosures where EMI and thermal reliability are critical. IC Role / Device Role / Timing Role: Precision on/off control of brushless fan modules using filtered PWM signals from analog front-end ASICs. Use Value: VCE(sat) ≤100 mV ensures <1.5 °C self-heating rise at 100 mA, maintaining stable thermal profile inside sealed medical housings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PUMB3H-Q | PNP/PNP complement with identical R1 = 4.7 kΩ, same SOT363 package and AEC-Q101 rating. | Used for high-side switching or complementary logic where sink current is required instead of source. | Select when designing push-pull outputs or interfacing with open-collector drivers needing inverted logic polarity. |
| PUMD6H-Q | NPN/PNP configuration with R1 = 4.7 kΩ on NPN side only; PNP side has no built-in resistor. | Enables mixed-signal level translation (e.g., 5 V TTL to 3.3 V CMOS) with asymmetric drive capability. | Choose for bidirectional interface circuits requiring one NPN switch and one PNP pull-up in shared control lines. |
Compared with PUMB3H-Q and PUMD6H-Q, PUMH7H-QF provides matched dual-NPN behavior ideal for parallel load switching, whereas PUMB3H-Q suits high-side or inverted logic, and PUMD6H-Q enables hybrid-level translation-selection depends on required output polarity and bias topology.

FAQ
What is the function of Pin 5 (I2) given R2 is open?
Pin 5 is the base terminal of the second NPN transistor (TR2) with no internal resistor (R2 = open). It requires external biasing-such as a series current-limiting resistor or active driver-to control TR2. This design allows flexible configuration: TR1 operates as a self-biased switch via R1, while TR2 supports custom gain or switching thresholds.
Can PUMH7H-QF replace BC847B dual transistors directly?
Yes, but only for TR1 functionality: Pin 1 (GND1), Pin 2 (I1), and Pin 6 (O1) replicate a BC847B with integrated 4.7 kΩ base resistor. TR2 (Pins 3, 4, 5) requires external biasing and does not mirror BC847B behavior unless supplemented with discrete components. Layout must accommodate SOT363 footprint, not SOT23.
Is the 175 °C rating applicable to both junction and ambient temperature?
The 175 °C rating is the maximum allowable junction temperature (Tj). Ambient temperature (Tamb) is rated to 175 °C only when thermal resistance conditions (e.g., PCB copper area, airflow) ensure Tj does not exceed 175 °C. Derating curves in Fig. 1 define safe power limits versus Tamb for given board layouts.
How does the open R2 affect thermal performance compared to fully resistor-equipped variants?
Open R2 eliminates power dissipation from that resistor, reducing total device self-heating by up to 0.5 mW at typical bias currents. This marginally improves thermal headroom-especially in high-density layouts-but does not alter the specified Rth(j-a) or derating curves, which are measured per device under standardized FR4 test conditions.
