Product details
Overview
PUMH9-QF from Nexperia is an AEC-Q101-qualified NPN/NPN resistor-equipped double transistor (RET) in SOT363-3 (SC-88) package, featuring integrated 10 kΩ input bias resistors (R1) and 47 kΩ feedback resistors (R2), 50 V VCEO, 100 mA output current per transistor, and optimized for digital switching in automotive control modules.
For engineers reviewing the PUMH9-QF datasheet, PUMH9-QF pinout, PUMH9-QF application, or PUMH9-QF equivalent, this device serves as a space- and BOM-optimized replacement for discrete BC847-Q pairs in low-power digital interface and load-switching circuits requiring automotive-grade reliability and simplified base-drive design.
Technical Context
This dual RET integrates two matched NPN transistors with monolithically embedded bias networks-R1 (10 kΩ) connected between base and input, R2 (47 kΩ) between collector and base-enabling direct logic-level drive without external resistors. Each transistor operates independently with open-base VCEO = 50 V and IO = 100 mA rating.
The device uses a common-emitter configuration per channel, with GND pins tied to respective emitter terminals (Pin 1 for TR1, Pin 4 for TR2), supporting independent signal routing. Thermal resistance is 417 K/W (per device, FR4 PCB), and junction temperature is rated to 150 °C, confirming suitability for under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage with base open; defines high-side switch headroom in 24 V automotive systems. |
| IO | 100 mA - Continuous output current per transistor; supports driving LEDs, small relays, or logic inputs without external current limiting. |
| R1 | 10 kΩ ±30% - Integrated base-input resistor; sets input current at ~0.25 mA for 2.5 V logic, eliminating discrete pull-up/pull-down components. |
| R2/R1 | 4.7 - Fixed feedback ratio enabling stable saturation with β-dependent gain compensation; reduces sensitivity to hFE variation across temperature. |
| Ptot (per device) | 300 mW at Tamb ≤ 25 °C - Total dissipation limit on standard FR4 PCB; supports dual-channel operation up to ~150 mW each under derated conditions. |
| hFE | ≥100 at VCE = 5 V, IC = 5 mA - Minimum DC current gain ensures reliable saturation with low base drive, critical for microcontroller GPIO interfacing. |
| VCE(sat) | ≤100 mV at IC = 5 mA, IB = 0.25 mA - Low saturation voltage minimizes power loss and heat generation in always-on or PWM-driven loads. |
Pinout & Package
SOT363-3 (SC-88/TSSOP6) plastic surface-mounted package: 1.3 mm × 2.2 mm footprint, 0.65 mm pitch, 0.95 mm max height, 6-pin transparent top view with pin 1 index marker.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter terminal of transistor TR1; must be connected to system ground or local reference for proper biasing of first channel. |
| 2 | I1 | Base input of TR1; accepts logic-level signals directly-no external resistor required due to integrated R1. |
| 3 | O2 | Collector output of TR2; provides switched high-side or low-side load connection depending on external circuit topology. |
| 4 | GND2 | Emiter terminal of transistor TR2; electrically isolated from GND1, enabling independent grounding or floating emitter configurations. |
| 5 | I2 | Base input of TR2; functionally identical to I1-supports dual independent digital control paths. |
| 6 | O1 | Collector output of TR1; complements O2 for dual-load or complementary-signal applications such as push-pull drivers. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network (R1 + R2) | Eliminates 4 external resistors per pair, reducing PCB area by ≥1.2 mm² and pick-and-place placements by 4x per channel. |
| AEC-Q101 qualification | Validated for automotive temperature range (−55 °C to 150 °C) and mechanical stress, enabling use in body control modules and lighting ECUs without additional qualification effort. |
| Matched dual-NPN topology | Enables synchronous switching or differential signaling without inter-device parameter mismatch; R2/R1 ratio tolerance (±20%) ensures consistent gain stabilization. |
| Low VCE(sat) (≤100 mV) | Reduces conduction loss to <0.5 mW at 5 mA load, extending battery life in always-on automotive sensors and enabling thermal-safe operation on compact PCBs. |
| Standard TSSOP6 footprint | Ensures compatibility with existing reflow soldering profiles and AOI inspection systems; solder land pattern matches IPC-7351B SOIC-6 density. |
Applications
| Automotive LED Tail Light Control | Industrial Digital Input Buffering |

Use Scenario: Controlling small 12 V DC blower motors in climate control systems via PWM from vehicle body controller. IC Role / Device Role / Timing Role: High-efficiency saturated switch handling 80–100 mA motor coil current; supports 1–20 kHz PWM without shoot-through risk. Use Value: 100 mV VCE(sat) limits power dissipation to <8 mW at full load, avoiding heatsinking and enabling integration into tight ECU housings. |
Use Scenario: Interfacing microcontroller outputs to 5 V/12 V relay coils in smart home appliances like washing machines and dishwashers. IC Role / Device Role / Timing Role: Logic-to-relay driver providing galvanic isolation via external optocoupler or direct coil drive; DC switching only. Use Value: Dual-channel layout allows single PUMH9-QF to drive two relays (e.g., water valve + pump), reducing component count versus discrete transistor solutions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-NPN resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847B-Q | Discrete NPN transistor without integrated resistors; requires external R1/R2 for same functionality. | Higher BOM count and layout area; suitable where design flexibility or trimming of bias values is needed. | Select when adjustable gain or non-standard R2/R1 ratios (e.g., 10:1) are required; not drop-in compatible. |
| PUMB9-Q | PNP/PNP complement with identical R1/R2 values and package; VCEO = 50 V, IO = 100 mA, but opposite polarity. | Used in high-side switching or complementary output stages; cannot replace PUMH9-Q in NPN-configured circuits. | Select for sourcing current instead of sinking; requires schematic redesign-no pin-for-pin or functional substitution. |
Compared with BC847B-Q and PUMB9-Q, PUMH9-QF delivers lowest assembly cost and smallest footprint for fixed-ratio NPN/NPN digital switching, while BC847B-Q offers design adaptability and PUMB9-Q enables complementary high-side control-not interchangeable without circuit revision.

FAQ
Is PUMH9-QF pin-compatible with other SOT363-3 packaged transistors?
Yes-PUMH9-QF uses the standardized TSSOP6 (SOT363-3) footprint defined in JEDEC MO-178AC, matching mechanical dimensions and solder pad layout of all SOT363-3 devices. However, electrical pin functions differ from generic dual transistors (e.g., MMBT5401/MMBT5551), so schematic verification is required before substitution.
What is the maximum ambient temperature for continuous operation?
PUMH9-QF is rated for continuous operation from −55 °C to +150 °C ambient temperature. At 150 °C, derating applies: total power dissipation must be reduced to ≤100 mW per device (per Figure 1), and VCEO remains guaranteed at 50 V per transistor under open-base conditions.
Can PUMH9-QF drive a 24 V relay coil directly?
Yes-each channel supports 100 mA output current and 50 V VCEO, sufficient for typical 24 V, 50–80 mA relay coils. Ensure coil flyback protection (e.g., 1N4007 diode) is added externally, as PUMH9-QF does not integrate clamp diodes. Verify VCE(sat) stays ≤100 mV at actual load current.
Does the R2/R1 ratio affect switching speed?
Yes-the 4.7 R2/R1 ratio stabilizes DC bias but introduces minor Miller-effect capacitance (Cc = 2.5 pF typical), limiting fT to 230 MHz. For >1 MHz switching, ensure gate drive rise/fall times exceed 10 ns; the device is optimized for DC and low-frequency PWM (<100 kHz), not RF or high-speed digital.
