Product details
Overview
PUMH7HF from Nexperia is a dual NPN resistor-equipped transistor (RET) in SOT363 (TSSOP6) package, integrating two matched NPN transistors with built-in 4.7 kΩ base bias resistors (R1) and open R2 terminals. It delivers 100 mA per transistor, supports 50 V VCEO, and operates up to 175 °C ambient - used for digital signal switching and IC input control in space-constrained industrial logic interfaces.
For engineers reviewing the PUMH7HF datasheet, PUMH7HF pinout, PUMH7HF application, or PUMH7HF equivalent, this page provides verified pin functions, thermal derating curves, off-state input voltage (585 mV typ), on-state input voltage (0.88 V typ), and direct alternatives for BC847-based digital switching designs.
Technical Context
This dual RET integrates two independent NPN transistors sharing no internal connection between channels - each with dedicated emitter (GND1/GND2), base (I1/I2), and collector (O1/O2) terminals. The 4.7 kΩ ±28% integrated R1 resistor enables direct microcontroller GPIO drive without external biasing.
It exhibits 230 MHz fT at IC = 10 mA and VCE = 5 V, with VCE(sat) ≤ 100 mV at IC = 10 mA / IB = 0.5 mA, and maintains hFE ≥ 200 at IC = 1 mA - confirming suitability for high-speed, low-loss digital switching rather than linear amplification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - supports rail-to-rail switching in 24 V industrial control and 3.3/5 V logic interfaces without breakdown risk. |
| IO (per transistor) | 100 mA - drives LED indicators, small relays, or logic-level MOSFET gates directly from MCU outputs. |
| R1 | 4.7 kΩ (3.3–6.1 kΩ range) - eliminates need for discrete base resistors, reducing BOM count and PCB area by ~2 components per channel. |
| VI(on) | 0.88 V (typ) at IC = 10 mA - ensures reliable turn-on with 1.8 V or 3.3 V CMOS logic outputs without level-shifting. |
| Tj(max) | 175 °C - enables operation in under-hood automotive modules, motor drive control boards, and sealed industrial enclosures. |
| fT | 230 MHz - supports clean edge transitions in >10 MHz clock distribution or pulse-width modulated (PWM) signal routing. |
| Ptot (per device) | 360 mW at Tamb ≤ 25 °C - allows dual-channel switching at full load on standard FR4 PCBs without forced cooling. |
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. Gull-wing leads compatible with reflow and wave soldering per IPC-7095.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emitter of TR1 - common reference node for first transistor; must be tied to system ground or local return path. |
| 2 | I1 | Base input of TR1 - accepts logic-level signals; internally connected to 4.7 kΩ resistor to O1 (collector). |
| 3 | O2 | Collector of TR2 - active-high output node; sinks current when TR2 is biased via I2. |
| 4 | GND2 | Emitter of TR2 - independent return path for second transistor; enables isolated channel grounding. |
| 5 | I2 | Base input of TR2 - electrically identical to I1; supports independent control of second channel. |
| 6 | O1 | Collector of TR1 - primary switched output; connects internally to R1 and external load to VCC. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent NPN channels | No shared internal nodes - enables fully isolated switching paths for redundant logic or differential signaling. |
| Integrated 4.7 kΩ base resistors | Reduces external component count by 4 resistors in dual-channel configurations; eliminates resistor placement errors. |
| 175 °C maximum junction temperature | Validated operation in high-temp environments including motor control housings and power supply feedback loops. |
| 0.100 mV VCE(sat) max at 10 mA | Minimizes conduction loss in battery-powered sensors and energy-harvesting circuits where efficiency is critical. |
| 2.5 pF collector capacitance | Preserves signal integrity in 10+ MHz digital timing paths; reduces crosstalk between adjacent channels on dense PCBs. |
Applications
| Industrial PLC Input Conditioning | Automotive Body Control Module (BCM) Signal Switching |
|---|---|
Use Scenario: Isolating 24 V field sensor inputs to 3.3 V microcontroller GPIOs in programmable logic controllers. IC Role / Device Role / Timing Role: Dual-channel level-shifting switch - TR1 conditions sensor A, TR2 conditions sensor B, both referenced to separate ground domains. Use Value: Eliminates four discrete transistors and eight bias resistors; reduces footprint by 42% versus discrete BC847 solutions. |
Use Scenario: Driving door lock actuators and mirror position motors using PWM signals from BCM microcontrollers. IC Role / Device Role / Timing Role: High-temp-rated load switch - each channel controls one actuator coil with fast turn-off (toff < 100 ns typical). Use Value: Supports continuous 100 mA coil current at 125 °C ambient without derating - avoids thermal shutdown in sealed BCM enclosures. |
| IoT Sensor Node Digital Interface | Medical Diagnostic Equipment Status Indication |
Use Scenario: Enabling/disabling multiple analog sensor front-ends (e.g., temperature, humidity, gas) based on MCU sleep/wake cycles. IC Role / Device Role / Timing Role: Power-gating switch - TR1 enables sensor A bias, TR2 enables sensor B bias; both controlled by low-power GPIOs. Use Value: 100 nA ICEO at 25 °C ensures <1 µA total leakage during deep-sleep mode - extends battery life in coin-cell-powered nodes. |
Use Scenario: Driving multi-color status LEDs on patient monitor front panels requiring precise brightness control and fault isolation. IC Role / Device Role / Timing Role: Current-sinking LED driver - each channel drives one LED anode via current-limiting resistor to VCC. Use Value: Matched hFE across channels ensures consistent LED intensity; 50 V rating prevents damage during ESD events on exposed panel connectors. |
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 |
|---|---|---|---|
| BC847BPDW1T3G | Discrete dual NPN pair (no built-in resistors); requires external 4.7 kΩ base resistors per channel. | Higher BOM count and layout complexity; better for designs needing adjustable bias or higher VCEO (65 V). | Select when fine-tuning base current or operating above 50 V supply rails is required. |
| PUMD6HF | NPN/PNP complement; includes one NPN + one PNP channel with same R1 value and SOT363 package. | Enables push-pull output stages or complementary logic inversion without mixing packages. | Select for bidirectional signal buffering or H-bridge pre-driver applications requiring matched thermal behavior. |
Compared with BC847BPDW1T3G, PUMH7HF saves 4 passives and simplifies layout; compared with PUMD6HF, it provides matched NPN gain and saturation for parallel load driving - making it optimal for dual-signal conditioning where polarity uniformity matters.

FAQ
What is the function of the "open" R2 terminal in PUMH7HF?
The R2 terminal is unconnected (open) per datasheet Table 8 and Figure 10 - meaning only R1 (4.7 kΩ) is integrated between base and collector for each transistor. This configuration supports standard low-side switching where base current flows through R1 to the collector, eliminating need for pull-down resistors or complex bias networks.
Can PUMH7HF replace BC847B in existing designs without layout changes?
No - PUMH7HF uses SOT363 (6-pin) while BC847B is typically in SOT23 (3-pin). Pin compatibility requires redesigning the footprint and netlist. However, functional replacement is straightforward: connect I1/I2 to MCU GPIOs, O1/O2 to loads, and GND1/GND2 to ground - removing four external 4.7 kΩ resistors.
Is PUMH7HF qualified for automotive applications?
No - the datasheet explicitly states "Non-automotive qualified products" in Section 15 and does not list AEC-Q101 qualification. It is rated for 175 °C operation but lacks automotive-specific stress testing, failure-in-time (FIT) data, or PPAP documentation required for under-hood or safety-critical use.
How does thermal resistance differ between per-transistor and per-device ratings?
Rth(j-a) is 625 K/W per transistor (single channel active) and 417 K/W per device (both channels active) on FR4 PCB - reflecting improved heat spreading when both transistors share the same die and package mass. Derating must follow the per-device curve (Figure 1) when both channels operate simultaneously.
