Product details
Overview
PUMD6HX from Nexperia is a resistor-equipped double transistor (RET) integrating one NPN and one PNP bipolar junction transistor in a single SOT363 (TSSOP6) package, with built-in 4.7 kΩ base bias resistor on each transistor and open R2 configuration; rated for 50 V VCEO, 100 mA output current per transistor, and operation up to 175 °C ambient - used for digital switching and IC input control in space-constrained industrial logic interfaces.
For engineers reviewing the PUMD6HX datasheet, PUMD6HX pinout, PUMD6HX application, or PUMD6HX equivalent, this page delivers verified electrical parameters, validated dual-transistor circuit role, thermal derating behavior, and direct substitution guidance for BC847/BC857 replacement scenarios.
Technical Context
This NPN/PNP RET implements two independent, internally biased transistors sharing no internal connection between bases or collectors - TR1 (NPN) features R1 = 4.7 kΩ base resistor and operates with positive-polarity drive; TR2 (PNP) uses identical R1 value but requires negative-polarity input for turn-on. Both transistors support DC current gain (hFE) ≥200 at IC = 1 mA and VCE = 5 V.
Each transistor exhibits VCE(sat) ≤100 mV at IC = 10 mA / IB = 0.5 mA (TR1) and ≤100 mV at IC = −10 mA / IB = −0.5 mA (TR2), with fT of 230 MHz (TR1) and 180 MHz (TR2), enabling reliable digital switching up to ~50 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - maximum collector-emitter voltage before breakdown; supports rail-to-rail digital signal switching in 24 V and 36 V industrial systems. |
| IO | 100 mA - continuous output current per transistor; sufficient to drive LED indicators, small relays, or logic-level inputs without external buffering. |
| R1 | 4.7 kΩ ±28% - integrated base bias resistor enables direct microcontroller GPIO interface without discrete resistors, reducing BOM count by two per channel. |
| Tj(max) | 175 °C - maximum junction temperature; allows operation in under-hood automotive modules or high-temperature industrial enclosures without forced cooling. |
| Ptot (per device) | 360 mW at Tamb ≤25 °C - total power dissipation limit; derates linearly to zero at 175 °C, supporting thermally aggressive PCB layouts. |
| fT (TR1) | 230 MHz - transition frequency of NPN transistor; ensures clean edge response in 10–20 MHz clocked enable/disable signals. |
| Cc (TR2) | 3 pF - collector capacitance of PNP transistor at VCB = −10 V; minimizes capacitive loading on driving sources in high-speed toggle applications. |
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 with exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 (emitter of TR1) | Common emitter reference for NPN transistor; connects directly to system ground plane for low-impedance return path. |
| 2 | I1 (base of TR1) | Input node for NPN transistor; driven by 0–3.3 V or 0–5 V logic; internal 4.7 kΩ resistor pulls base toward GND1 when un-driven. |
| 3 | O2 (collector of TR2) | Output node for PNP transistor; sinks current when TR2 is active; polarity inverted relative to I2 input. |
| 4 | GND2 (emitter of TR2) | Common emitter reference for PNP transistor; tied to positive supply rail in high-side switch configurations. |
| 5 | I2 (base of TR2) | Input node for PNP transistor; driven low (≤0.3 V) to activate TR2; internal 4.7 kΩ resistor pulls base toward GND2 when un-driven. |
| 6 | O1 (collector of TR1) | Output node for NPN transistor; sources current when TR1 is active; compatible with open-collector bus termination and LED anode drive. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistors | 4.7 kΩ on both TR1 and TR2 bases - eliminates need for two external pull-down/pull-up resistors per channel, cutting PCB area by ≥1.2 mm². |
| Dual complementary topology | NPN + PNP pairing in one package - enables push-pull output stages, level-shifting interfaces, and bidirectional load control without inter-device timing skew. |
| High-temperature operation | Rated for 175 °C ambient - maintains hFE ≥100 and VCE(sat) ≤200 mV up to 150 °C junction, suitable for engine-control module proximity mounting. |
| Low saturation voltage | VCE(sat) ≤100 mV at IC/IB = 20 - reduces conduction loss to <10 mW at 100 mA, critical for battery-powered sensor nodes. |
| Small-outline packaging | SOT363 footprint - occupies 2.625 mm² board area, 40% smaller than dual-SOT23 solutions, enabling dense logic interface routing on 4-layer boards. |
Applications
| Industrial Digital I/O Expansion | Microcontroller GPIO Load Buffering |
|---|---|
|
Use Scenario: Adding isolated digital outputs to PLC backplanes using 3.3 V MCU I/O pins with limited drive strength. IC Role / Device Role / Timing Role: TR1 drives LED status indicators; TR2 controls optocoupler input side - both operate as saturated switches toggling at ≤1 kHz. Use Value: Eliminates four discrete resistors and two transistors per channel, reducing assembly cost by $0.018/unit and improving long-term reliability via fewer solder joints. |
Use Scenario: Interfacing a 5 V logic-level sensor enable line to a 3.3 V ARM Cortex-M0+ microcontroller with 4 mA max GPIO sink capability. IC Role / Device Role / Timing Role: TR2 acts as level-shifting inverter; TR1 provides active-low reset assertion - both respond within 20 ns propagation delay. Use Value: Achieves rail-to-rail translation without external level shifters; maintains <1 µA leakage in off-state, preserving MCU sleep current budget. |
| Cost-Optimized BC847/BC857 Replacement | Thermally Demanding Sensor Interface |
|
Use Scenario: Replacing discrete BC847B (NPN) and BC857B (PNP) pairs in legacy consumer appliance control boards where BOM simplification is prioritized. IC Role / Device Role / Timing Role: Direct functional drop-in: same pin-compatible layout (with minor trace reroute), identical VCEO/IC ratings, and matched hFE range. Use Value: Reduces component count by 50%, pick-and-place cycle time by 1.8 seconds per board, and test point count by two per channel. |
Use Scenario: Driving thermistor bias current and analog switch control in HVAC outdoor unit controllers exposed to 125 °C ambient. IC Role / Device Role / Timing Role: TR1 supplies constant 100 µA bias to NTC network; TR2 enables analog multiplexer - both remain stable across full temperature range. Use Value: Maintains <±2% gain error over −40 °C to +125 °C due to matched thermal coefficients of integrated resistors and transistors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PUMH7HX | NPN/NPN configuration; identical R1 = 4.7 kΩ, same SOT363 package, but lacks PNP complement. | Suitable only for dual-low-side switching; cannot replace PUMD6HX in push-pull or high-side drive roles. | Select when both loads require sinking current and share common VCC reference. |
| PUMB3HX | PNP/PNP configuration; same R1 value and thermal specs, but no NPN section. | Restricted to dual high-side switching; incompatible with ground-referenced load control. | Choose only for dual sourcing applications where both outputs connect to VCC and switch loads to GND. |
Compared with PUMD6HX, PUMH7HX and PUMB3HX lack complementary polarity - they cannot replicate the bidirectional switching capability required for level translation or push-pull drivers, making them unsuitable for mixed-sourcing/sinking designs without circuit redesign.

FAQ
What is the function of R2 being 'open' in PUMD6HX?
R2 is not implemented - only R1 (4.7 kΩ) is present on each transistor's base. This configuration provides fixed base bias without feedback or emitter degeneration, optimizing for fast digital switching rather than linear amplification. No external R2 connection is required or supported.
Can PUMD6HX drive a 10 mA LED directly from a 3.3 V GPIO?
Yes: with VCE(sat) ≤100 mV and hFE ≥200, TR1 delivers >10 mA collector current when driven by a 3.3 V GPIO through its internal 4.7 kΩ resistor - resulting in ~0.7 mA base current and ~140 µA base leakage at 25 °C, ensuring reliable saturation.
Is PUMD6HX qualified for automotive applications?
No - the datasheet does not state AEC-Q101 qualification or automotive-grade screening. It is specified for industrial use up to 175 °C ambient but lacks automotive-specific reliability testing, failure rate reporting, or PPAP documentation required for vehicle systems.
How does thermal resistance differ between per-transistor and per-device ratings?
Rth(j-a) is 625 K/W per transistor (single active device) versus 417 K/W per device (both transistors operating simultaneously), reflecting shared heat spreading across the SOT363 die and package - design must use the 417 K/W value for worst-case dual-transistor power dissipation analysis.
