Product details
Overview
PUMD16-QX from Nexperia is a resistor-equipped double transistor (RET) integrating one NPN and one PNP silicon bipolar transistor with built-in bias resistors (R1 = 22 kΩ, R2 = 47 kΩ) in a single SOT363-3 (TSSOP6) package. It delivers 100 mA output current per transistor, supports 50 V collector-emitter breakdown voltage, and is qualified to AEC-Q101 for automotive signal-level switching and level translation.
For engineers reviewing the PUMD16-QX datasheet, PUMD16-QX pinout, PUMD16-QX application, or PUMD16-QX equivalent, this device serves as a space- and BOM-optimized replacement for discrete NPN+PNP pairs in digital logic interfacing, low-current peripheral control, and bidirectional I/O buffering where simplified biasing and automotive-grade reliability are required.
Technical Context
The PUMD16-QX implements two monolithically integrated bipolar transistors - TR1 (NPN) and TR2 (PNP) - each with dedicated on-chip base bias networks. TR1 features R1 = 22 kΩ and R2 = 47 kΩ connected between base and emitter, enabling direct TTL/CMOS-compatible drive without external resistors. TR2 shares identical resistor values but operates with inverted polarity, supporting complementary switching in push-pull or dual-rail configurations.
Its SOT363-3 package provides six terminals with isolated emitter connections (GND1, GND2), separate inputs (I1, I2), and cross-coupled outputs (O1 = collector of TR1, O2 = collector of TR2). Thermal resistance is 417 K/W (device-level, free air, FR4 PCB), and junction temperature is rated to 150 °C - consistent with under-hood automotive ambient requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage for both transistors; enables use in 24 V automotive systems with margin. |
| IO | 100 mA - Continuous DC output current per transistor; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 22 kΩ ±30% - Integrated input bias resistor; sets base current for standard 3.3 V/5 V logic drive without external components. |
| R2/R1 | 2.1 - Fixed internal resistor ratio; ensures stable saturation and predictable turn-on threshold across temperature. |
| hFE | 80 min at IC = 5 mA, VCE = 5 V - Minimum DC current gain; guarantees reliable switching with low base drive overhead. |
| VCE(sat) | 150 mV max at IC = 10 mA, IB = 0.5 mA - Low saturation voltage minimizes power loss and heat generation in active switching. |
| Ptot (device) | 300 mW - Total power dissipation limit at Tamb ≤ 25 °C; defines thermal design envelope for PCB layout. |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mounted package: 2.2 mm × 1.35 mm footprint, 0.65 mm pitch, 0.95 mm max height, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1 (NPN); must be tied to system ground or common reference for proper NPN biasing. |
| 2 | I1 | Base input for TR1 (NPN); accepts 3.3 V/5 V logic high to activate TR1 collector output (O1). |
| 3 | O2 | Collector output for TR2 (PNP); sinks current when I2 is pulled low; complements TR1 for bidirectional control. |
| 4 | GND2 | Emiter connection for TR2 (PNP); requires connection to positive rail or pull-up source for PNP operation. |
| 5 | I2 | Base input for TR2 (PNP); driven low to activate TR2; compatible with open-drain or inverted logic signals. |
| 6 | O1 | Collector output for TR1 (NPN); sources current when I1 is high; used for active-high switching or level shifting. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors (R1/R2) | Eliminates four external resistors per RET pair, reducing PCB area by >30% and eliminating placement errors. |
| AEC-Q101 qualification | Validated for automotive applications including engine control modules, body electronics, and ADAS sensor interfaces. |
| NPN/PNP complementarity | Enables single-package push-pull, inverter, or dual-rail level-shifting circuits without inter-device timing skew. |
| Low VCE(sat) and hFE stability | Maintains <150 mV saturation voltage and ≥80 hFE from –40 °C to +100 °C, ensuring robust operation across vehicle thermal zones. |
| Standard TSSOP6 footprint | Compatible with automated SMT assembly lines and reflow profiles; solder land pattern defined per JEDEC MO-178. |
Applications
| Automotive Door Module Driver | Industrial PLC Input Buffer |
|---|---|
Use Scenario: Driving window lift motor direction control logic and mirror fold/unfold signals in door ECUs. IC Role / Device Role / Timing Role: Dual-transistor interface translating microcontroller GPIOs to isolated, polarity-matched loads with no external biasing.

Use Value: Enables bidirectional signal conditioning in one 2.2 mm × 1.35 mm footprint, minimizing trace length and EMI susceptibility. |
| USB-C Port Power Switch Control | Smart HVAC Fan Speed Interface |
Use Scenario: Controlling USB-C CC line pull-up/pull-down resistors during port role negotiation.

Use Value: Guarantees sub-1 µs transition between roles via matched NPN/PNP turn-on characteristics and low Cc (<3 pF). |
Use Scenario: Interfacing PWM fan speed commands from MCU to 12 V brushless fan drivers in climate control units. IC Role / Device Role / Timing Role: Inverting and non-inverting gate driver buffer; isolates MCU pins from inductive kickback and supply noise. Use Value: Provides 100 mA peak drive capability with <150 mV VCE(sat), preventing thermal derating at 10 kHz PWM frequencies. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PUMH16-Q | NPN/NPN configuration; identical R1/R2 values and SOT363-3 package. | Used where dual-sourcing or symmetrical high-side switching is needed instead of complementary drive. | Select when both outputs require NPN topology (e.g., two active-high loads sharing common ground). |
| PUMB16-Q | PNP/PNP configuration; same resistor values and package; no NPN element. | Preferred for dual active-low or high-side switch applications requiring negative logic compatibility. | Choose when driving two loads referenced to VCC (e.g., LED anodes or relay coils) with independent enable control. |
Compared with PUMH16-Q and PUMB16-Q, the PUMD16-QX uniquely supports true complementary switching in one package - enabling compact push-pull, inverter, or bidirectional bus interface designs that would otherwise require two discrete RETs or complex routing.

FAQ
What is the maximum operating temperature for PUMD16-QX?
The PUMD16-QX has a maximum junction temperature (Tj) of 150 °C and an ambient operating range of –65 °C to +150 °C. Its thermal resistance (Rth(j-a)) is 417 K/W on FR4 PCB, meaning it can dissipate up to 300 mW at 25 °C ambient before reaching Tj = 150 °C. Derating is required above 25 °C ambient per the datasheet curve.
Can PUMD16-QX replace discrete BC847/BC857 pairs?
Yes - the PUMD16-QX replaces one BC847 (NPN) and one BC857 (PNP) plus four external bias resistors. Its integrated R1 = 22 kΩ and R2 = 47 kΩ match typical 5 V logic drive requirements, and its 100 mA IO exceeds BC847/BC857's 100 mA rating. Pinout differs, so PCB layout must follow SOT363-3 mapping, not SC-70.
Is the marking code 'D1%' unique to PUMD16-QX?
Yes - the top-side marking 'D1%' (where % is a site-specific code) is assigned exclusively to PUMD16-QX per Nexperia's ordering information table. It distinguishes this part from PUMH16-Q (marked 'D2%') and PUMB16-Q (marked 'D3%') in the same SOT363-3 package, enabling visual identification during assembly and inspection.
Does PUMD16-QX support 3.3 V logic directly?
Yes - VI(on) is specified at 1.1 V (typical) and VI(off) at 0.5 V (typical) for TR1 (NPN), allowing clean turn-on with 3.3 V CMOS outputs. For TR2 (PNP), the input threshold is inverted: I2 must be pulled below 0.5 V to activate O2. No level-shifting circuitry is needed for standard 3.3 V/5 V microcontrollers.
