Product details
Overview
PUMD2-QH from Nexperia is a resistor-equipped double transistor (RET) integrating one NPN and one PNP silicon bipolar junction transistor in a single SOT363-3 (TSSOP6) package, with built-in bias resistors R1 = 22 kΩ and R2 = 22 kΩ per channel, rated for 50 V VCEO, 100 mA output current, and qualified to AEC-Q101 for automotive signal-level switching applications such as I/O buffering and logic-level translation.
For engineers reviewing the PUMD2-QH datasheet, PUMD2-QH pinout, PUMD2-QH application, or PUMD2-QH equivalent, this device serves as a space- and BOM-optimized replacement for discrete NPN+PNP pairs in low-current digital interface circuits where input threshold control, reduced PCB footprint, and automotive-grade reliability are required.
Technical Context
This dual RET implements two independent transistor channels - TR1 (NPN) and TR2 (PNP) - each with integrated base biasing networks enabling direct logic-level drive without external resistors. The NPN channel delivers hFE ≥ 60 at IC = 5 mA and VCE = 5 V, while the PNP channel supports symmetric operation with matched R1/R2 ratio (0.8–1.2) and complementary saturation behavior (VCEsat ≤ 150 mV).
Thermal performance is specified for FR4 PCB mounting: per-device total power dissipation is 300 mW at Tamb ≤ 25 °C, with junction-to-ambient thermal resistance of 417 K/W. The device operates across –55 °C to +150 °C ambient and supports transient pulse operation up to 100 MHz fT (TR1) and 180 MHz fT (TR2).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive and industrial logic interfaces. |
| IO | 100 mA - Continuous output current per transistor; sufficient for driving LEDs, small relays, and CMOS/TTL inputs. |
| R1 / R2 | 22 kΩ / 22 kΩ - Integrated base bias resistors eliminate need for external components and ensure consistent turn-on thresholds. |
| hFE | ≥ 60 - DC current gain at IC = 5 mA; ensures reliable saturation with low base drive current (e.g., 0.5 mA for 10 mA IC). |
| VCEsat | ≤ 150 mV - Low saturation voltage minimizes power loss and heat generation in switching applications. |
| fT | 230 MHz (TR1 NPN), 180 MHz (TR2 PNP) - Transition frequency supports high-speed digital switching up to ~10–20 MHz edge rates. |
Pinout & Package
Package: SOT363-3 (TSSOP6), 1.3 mm × 2.2 mm × 0.95 mm profile, surface-mount plastic package with gull-wing leads and exposed pad not present.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1 (NPN); common reference node for first channel. |
| 2 | I1 | Base input for TR1 (NPN); driven directly by logic-level signals (VI(on) = 1.7–2.5 V). |
| 3 | O2 | Collector output for TR2 (PNP); active-low switching node with VCE = –50 V max rating. |
| 4 | GND2 | Emiter connection for TR2 (PNP); separate ground reference for second channel. |
| 5 | I2 | Base input for TR2 (PNP); accepts negative-polarity logic or inverted drive signals. |
| 6 | O1 | Collector output for TR1 (NPN); active-high switching node with standard positive-side load configuration. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Qualified for automotive applications including engine control modules and body electronics; validated for temperature cycling, HAST, and mechanical shock. |
| Integrated bias network | R1 = R2 = 22 kΩ ±30 % per channel eliminates external resistors and reduces layout sensitivity to parasitic coupling. |
| Complementary NPN/PNP pairing | Enables push-pull or totem-pole output stages without level-shifting circuitry; supports bidirectional logic interfacing. |
| Low VCEsat and high hFE | Ensures full saturation with minimal base current (e.g., 0.5 mA drives 10 mA load), reducing MCU GPIO loading and power consumption. |
| Small-footprint SOT363-3 | 0.65 mm lead pitch and 2.2 mm × 1.3 mm body area saves >60 % board space versus two discrete SOT23 transistors. |
Applications
| Automotive Door Module Interface | Industrial PLC Input Buffer |
|---|---|
Use Scenario: Level-shifting and noise-immune signal conditioning between 3.3 V microcontroller GPIOs and 12 V/24 V vehicle bus lines. IC Role / Device Role / Timing Role: Dual-channel RET acts as bidirectional logic translator and ESD-robust input buffer, with NPN handling high-side sensing and PNP managing low-side pull-down. Use Value: Eliminates four external resistors and two discrete transistors per channel, reducing BOM count by 67 % and improving signal integrity via matched internal R1/R2 ratio (0.8–1.2). |
Use Scenario: Converting 24 V dry-contact sensor inputs into clean 5 V CMOS-compatible signals for programmable logic controllers. IC Role / Device Role / Timing Role: PNP channel sinks current from 24 V source through optocoupler LED; NPN channel buffers resulting logic state to FPGA input. Use Value: Built-in 22 kΩ bias resistors set precise VI(on)/VI(off) thresholds (1.7–2.5 V / 0.8–1.1 V), ensuring noise margin >1.2 V at 25 °C and stable operation over –40 °C to +100 °C. |
| USB-C Port Power Switch Control | Smart Home Sensor Hub Signal Conditioning |
Use Scenario: Enabling/disabling VBUS path and CC line termination in USB-C receptacle designs using a single 3.3 V MCU GPIO. IC Role / Device Role / Timing Role: NPN switches 5 V VBUS enable line; PNP controls CC line pull-up/pull-down resistors under firmware control. Use Value: 100 mA output capability supports USB-C 3 A mode loads; 50 V VCEO rating provides headroom against inductive transients during hot-plug events. |
Use Scenario: Interfacing multiple analog/digital sensors (PIR, temp, humidity) with different supply domains (3.3 V, 5 V, battery) in battery-powered IoT hubs. IC Role / Device Role / Timing Role: RET pair isolates MCU I/O from sensor power rails while providing level-adapted enable and interrupt signals. Use Value: Low 150 mV VCEsat limits self-heating during continuous 10 mA sensor biasing; 200 mW per-transistor power rating supports sustained operation in sealed enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PUMH1-Q | NPN/NPN complement; identical R1/R2 values but no PNP channel. | Suitable only for dual-sourcing or parallel NPN outputs; lacks complementary switching capability. | Select when both channels require sourcing (high-side) drive and no sink capability is needed. |
| PUMB1-Q | PNP/PNP complement; same bias network but no NPN channel. | Applicable for dual-sinking configurations (e.g., dual open-collector outputs); cannot provide active-high outputs. | Choose for redundant low-side switching or mirrored PNP logic where polarity matching is critical. |
Compared with PUMD2-QH, PUMH1-Q and PUMB1-Q offer channel duplication within a single polarity but lack the NPN/PNP functional asymmetry required for true push-pull or level-translating topologies - making PUMD2-QH uniquely suited for mixed-polarity interface consolidation.

FAQ
Is PUMD2-QH pin-compatible with other SOT363-3 RETs like PUMH1-Q?
No, PUMD2-QH is not pin-compatible with PUMH1-Q or PUMB1-Q. While all share the SOT363-3 package, pin functions differ: PUMD2-QH assigns GND1/I1/O2/GND2/I2/O1 to pins 1–6, whereas PUMH1-Q uses GND/I1/O1/GND/I2/O2. Swapping them without layout revision causes incorrect biasing and potential latch-up.
What is the maximum allowable input voltage on I1 and I2 pins?
The absolute maximum input voltage on I1 (TR1 base) is +10 V, and on I2 (TR2 base) is –40 V, per the limiting values table. Exceeding these risks permanent damage to the internal bias resistors or transistor junctions. For safe 3.3 V or 5 V logic interfacing, no series resistor is required due to the integrated R1/R2 network.
Does PUMD2-QH support simultaneous conduction of both transistors?
Yes - TR1 (NPN) and TR2 (PNP) operate independently with separate emitters (GND1 and GND2), allowing concurrent switching without cross-conduction. However, shared supply routing must avoid ground bounce; best practice is to route GND1 and GND2 to distinct low-impedance nodes on the PCB.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 0.8–1.2 ensures matched base current scaling between input and feedback paths, stabilizing VI(on) and VI(off) thresholds across temperature and process variation. A ratio near unity minimizes hysteresis and improves noise immunity in digital input applications, especially at –40 °C to +100 °C operating range.
