Product details
Overview
PUMD6-QX from Nexperia is a dual-channel NPN/PNP resistor-equipped transistor (RET) in SOT363 (SC-88) package, integrating built-in 4.7 kΩ input bias resistors and open R2 configuration. It delivers 50 V VCEO, 100 mA output current per channel, and AEC-Q101 qualification for automotive-grade switching of low-current digital loads.
For engineers reviewing the PUMD6-QX datasheet, PUMD6-QX pinout, PUMD6-QX application, or PUMD6-QX equivalent, this device serves as a space- and BOM-optimized replacement for discrete BC847/BC857 pairs in level-shifting, peripheral driver, and IC input control circuits where simplified biasing and reduced placement cost are critical.
Technical Context
The PUMD6-QX integrates two monolithic transistors - TR1 (NPN) and TR2 (PNP) - each with a dedicated 4.7 kΩ input resistor (R1) and no second bias resistor (R2 = open). Its dual-polarity structure enables complementary signal inversion and push-pull interface without external base resistors.
It operates across –65 °C to +150 °C ambient, supports 5 V VEBO (NPN) and –5 V VEBO (PNP), and maintains hFE ≥200 at IC = 1 mA, VCE = 5 V (TR1) and IC = –1 mA, VCE = –5 V (TR2), enabling reliable digital on/off control under industrial and automotive thermal stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 24 V industrial bus and 12 V automotive rail interfacing. |
| IO | 100 mA - Continuous output current per transistor; sufficient for driving LEDs, small relays, and logic inputs. |
| R1 | 4.7 kΩ ±29% - Integrated base-input resistor; eliminates external bias components and reduces PCB footprint by ~2 parts per channel. |
| VCE(sat) | 100 mV max (TR1), 100 mV max (TR2) - Low saturation voltage ensures minimal power loss and heat generation at rated load. |
| fT | 230 MHz (TR1), 180 MHz (TR2) - Transition frequency confirms suitability for high-speed digital switching up to ~10–20 MHz edge rates. |
| Ptot (per device) | 300 mW - Total power dissipation limit at Tamb ≤25 °C on FR4 PCB; enables compact layout 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; designed for reflow and wave soldering per IPC-7095 guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 (emitter) | Emitter connection for TR1 (NPN); common reference node for first channel. |
| 2 | I1 (base input) | Input terminal for TR1; internally connected to 4.7 kΩ R1 resistor leading to base. |
| 3 | O2 (collector output) | Collector connection for TR2 (PNP); active-low output node. |
| 4 | GND2 (emitter) | Emitter connection for TR2 (PNP); independent ground return for second channel. |
| 5 | I2 (base input) | Input terminal for TR2; internally connected to 4.7 kΩ R1 resistor leading to base. |
| 6 | O1 (collector output) | Collector connection for TR1 (NPN); active-high output node. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in 4.7 kΩ bias resistors | Eliminates need for two external base resistors per channel, reducing component count by 4× vs. discrete BC847+BC857 pair. |
| AEC-Q101 qualified | Validated for automotive applications including body control modules and sensor interfaces requiring extended temperature and reliability compliance. |
| Dual NPN/PNP topology | Enables complementary logic-level translation and bidirectional signal conditioning without cross-coupling or timing skew. |
| Low VCE(sat) (≤100 mV) | Minimizes conduction loss and self-heating during sustained 100 mA switching, improving thermal margin in dense layouts. |
| SOT363 footprint | 0.95 mm height and 2.1 mm length allow placement in space-constrained modules such as automotive ECUs and IoT sensor nodes. |
Applications
| Automotive Body Control Unit | Industrial PLC Digital Output Module |
|---|---|
Use Scenario: Driving LED status indicators and small solenoid valves in door module PCBs. IC Role / Device Role / Timing Role: Dual RET acts as level-translating switch: TR1 sinks current for active-high indicators; TR2 sources current for active-low valve drivers. Use Value: Reduces bill-of-materials by replacing two discrete transistors + four resistors with one AEC-Q101-qualified device, lowering assembly cost and test complexity. |
Use Scenario: Isolating microcontroller GPIO pins from 24 V field-side loads in DIN-rail mounted I/O cards. IC Role / Device Role / Timing Role: Provides galvanically isolated digital output stage with integrated pull-up/pull-down biasing for robust noise immunity. Use Value: Enables direct MCU-to-load connection without external bias network, cutting PCB area by >1.5 mm² per channel and improving ESD robustness via internal resistor protection. |
| USB-C Port Power Switch Controller | Smart Home Sensor Hub Interface |
Use Scenario: Enabling/disabling VBUS path and CC line termination in USB-C port controllers. IC Role / Device Role / Timing Role: TR1 controls high-side VBUS switch enable; TR2 manages CC line pull-up/down selection under USB PD negotiation. Use Value: Single-device dual polarity control meets USB Type-C specification timing requirements while minimizing propagation delay mismatch (<5 ns typical between channels). |
Use Scenario: Interfacing low-power MCU GPIOs to 3.3 V/5 V mixed-voltage sensors (e.g., PIR, humidity, button matrix). IC Role / Device Role / Timing Role: Acts as bidirectional level shifter and current amplifier for sensor wake-up signals and interrupt lines. Use Value: Built-in R1 resistors prevent floating inputs during MCU sleep states, eliminating need for external weak pull-ups and reducing standby current by ~2 µA per channel. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-polarity resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847B/BC857B + external 4.7 kΩ resistors | No integrated resistors; requires 4 discrete 0402 resistors and additional routing. | Higher assembly cost and larger footprint; suitable only when RET availability is constrained. | Select only if legacy design reuse or parametric fine-tuning (e.g., non-standard R1 values) is required. |
| PUMD12-Q | Dual NPN only; same package but no PNP channel; R1 = 22 kΩ, R2 = 47 kΩ. | Limited to single-polarity applications like parallel GPIO expansion; cannot replace PUMD6-QX in complementary switching. | Choose only for NPN-only digital fan-out or buffer applications where PNP functionality is unnecessary. |
Compared with BC847B/BC857B pairs, PUMD6-QX saves 4 passives and 2 placement steps; versus PUMD12-Q, it uniquely supports true complementary drive essential for H-bridge pre-driver and bidirectional bus control.

FAQ
What is the maximum operating junction temperature for PUMD6-QX?
The absolute maximum junction temperature (Tj) is 150 °C, validated per AEC-Q101 stress testing. Derating begins above 25 °C ambient, with total device power dissipation dropping linearly to zero at 150 °C per the 416 K/W Rth(j-a) curve in free air on FR4 PCB.
Can PUMD6-QX be used in AC-coupled signal paths?
No - PUMD6-QX is a DC-coupled switching device with fixed bias resistors optimized for digital on/off operation. Its R1 resistor ties the base directly to input, preventing AC coupling; use dedicated RF transistors or analog switches for signal-path applications.
Is R2 truly unconnected, or is it internally shorted or pulled?
R2 is open - not shorted or pulled. The datasheet explicitly states "R2 = open" in both title and Table 8 test conditions, and pin diagrams show no internal connection between R2 terminals. This allows full user control over second-stage biasing if needed externally.
How does PUMD6-QX handle reverse polarity on the PNP channel?
The PNP channel (TR2) is rated for –50 V VCBO and –5 V VEBO; its input (I2) and output (O2) terminals are polarity-aware. Applying positive voltage to I2 or O2 beyond VEBO/VCBO limits risks latch-up or breakdown - proper negative-bias design per Figure 18 is mandatory.
