Product details
Overview
PUMH7H-QX 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-circuit R2. It functions as a dual digital switching element for level translation and load control in space-constrained automotive and industrial PCBs.
For engineers reviewing the PUMH7H-QX datasheet, PUMH7H-QX pinout, PUMH7H-QX application, or PUMH7H-QX equivalent, this device serves as a drop-in replacement for BC847-based dual-transistor configurations-offering reduced BOM count, simplified layout, and AEC-Q101 qualification for under-hood signal conditioning and microcontroller I/O interfacing.
Technical Context
This dual NPN RET integrates two matched transistors with independent emitter-grounded topology and dedicated base resistors. Each channel features open-base VCEO = 50 V, IO = 100 mA, and hFE ≥ 200 at IC = 1 mA, enabling robust digital switching without external bias networks.
The device uses a monolithic die structure with shared thermal path and operates across −55 °C to +175 °C ambient. Its Rth(j-a) = 417 K/W (per device) and Rth(j-sp) = 230 K/W support high-temperature reliability in engine control units and powertrain modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with margin. |
| IO | 100 mA - Continuous output current per transistor; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 4.7 kΩ ±28% - Integrated base bias resistor; eliminates need for discrete pull-up/pull-down components. |
| Tj max | 175 °C - Junction temperature limit; qualified per AEC-Q101 for under-hood applications. |
| fT | 230 MHz - Transition frequency at IC = 10 mA; supports fast digital switching up to ~10 MHz. |
| VCE(sat) | 100 mV max at IC = 10 mA / IB = 0.5 mA; ensures low conduction loss in active switching mode. |
| hFE | ≥200 at VCE = 5 V, IC = 1 mA; provides stable current gain over −40 °C to +125 °C operating range. |
Pinout & Package
SOT363 (TSSOP6) plastic surface-mount package: 2.1 mm × 1.25 mm × 0.95 mm body, 0.65 mm lead pitch, FR4-compatible footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection of TR1; common reference for first transistor channel. |
| 2 | I1 | Base input of TR1; driven through internal R1 resistor (4.7 kΩ). |
| 3 | O2 | Collector output of TR2; active-high switching node for second channel. |
| 4 | GND2 | Emiter connection of TR2; isolated ground return for second transistor channel. |
| 5 | I2 | Base input of TR2; driven directly (R2 = open), requiring external bias if used. |
| 6 | O1 | Collector output of TR1; primary switching output with integrated base resistor. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET topology | Two independent NPN transistors with one integrated 4.7 kΩ base resistor (R1) and open R2; reduces component count by ≥2 resistors per channel. |
| AEC-Q101 qualification | Stress-tested per Automotive Electronics Council standard; validated for engine control, body electronics, and ADAS sensor interfaces. |
| High-temperature operation | Full functionality from −55 °C to +175 °C ambient; supports placement near heat sources without derating. |
| Low saturation voltage | VCE(sat) ≤ 100 mV at IC/IB = 20; minimizes power dissipation in always-on or PWM-driven loads. |
| Small-outline packaging | SOT363 footprint saves >60% board area vs. SO-8 dual transistors; compatible with standard reflow soldering profiles. |
Applications
| Automotive Body Control Module | Industrial PLC Input Stage |
|---|---|
Use Scenario: Level-shifting and isolation of 12 V/24 V switch signals into 3.3 V/5 V microcontroller GPIOs. IC Role / Device Role / Timing Role: Dual-channel digital buffer with integrated biasing; handles wake-up detection and door lock actuation signals.

Use Scenario: Interfacing 24 V DC field sensors (e.g., proximity switches) to programmable logic controller digital inputs. IC Role / Device Role / Timing Role: Input conditioning stage providing current-limited, noise-immune signal conversion. Use Value: Enables direct connection without external pull-ups or clamping diodes; supports 10 kHz switching in DIN-rail mounted controllers. |
| LED Driver for Dashboard Indicators | Microcontroller I/O Expander Interface |
Use Scenario: Driving multiplexed LED segments in automotive instrument clusters with minimal PCB real estate. IC Role / Device Role / Timing Role: Constant-current sink driver using saturated switching mode for uniform brightness control. Use Value: Delivers 100 mA per channel with <100 mV dropout; allows direct PWM dimming at 1–2 kHz without external gate drivers. |

Use Value: Provides 200× DC current gain with built-in biasing; avoids need for discrete transistor arrays or dedicated I/O expanders. |
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 pair without integrated resistors; requires external 4.7 kΩ base bias network per channel. | Higher BOM count and layout complexity; not AEC-Q101 qualified out-of-box. | Select when design requires adjustable base drive or non-standard resistor values. |
| PUMD6H-Q | NPN/PNP complement RET; includes R1 = 4.7 kΩ on NPN side and R2 = 10 kΩ on PNP side. | Enables push-pull output stages; unsuitable for dual-sink or dual-source topologies. | Select when complementary switching (e.g., half-bridge gate drive) is required instead of dual NPN logic buffering. |
Compared with BC847BPDW1T3G and PUMD6H-Q, PUMH7H-QX uniquely delivers dual-NPN functionality with single-channel bias integration and automotive qualification-reducing layout risk and validation effort for cost-sensitive, high-reliability digital interface designs.

FAQ
Is PUMH7H-QX pin-compatible with BC847BDW1T3G?
No. PUMH7H-QX uses SOT363 (6-pin) with GND/I/O pin assignments optimized for RET operation, while BC847BDW1T3G uses SOT363 but with different internal connectivity (dual discrete transistors, no integrated resistors). Pin mapping differs for I1/I2 and O1/O2 terminals, requiring PCB redesign.
What is the function of R2 being open in PUMH7H-QX?
R2 is unconnected (open) on the second transistor's base, meaning TR2 requires external biasing-either via pull-up resistor or direct MCU GPIO drive. This configuration allows flexible control of TR2 independent of TR1's integrated R1-biased operation, supporting asymmetric switching schemes.
Can PUMH7H-QX be used in linear amplification mode?
No. The device is characterized and qualified only for switching operation. Its hFE variation across temperature and its lack of linear-region specifications (e.g., output conductance, distortion metrics) confirm it is intended for digital on/off applications-not analog amplification.
Does PUMH7H-QX require derating above 25 °C ambient?
Yes. Total device power dissipation must be derated linearly above 25 °C ambient per Fig. 1: Ptot = 360 mW − (Tamb − 25) × 0.864 mW/°C. At 100 °C ambient, maximum allowable power drops to 289 mW, limiting combined channel current under sustained load.
