Product details
Overview
PUMD24 from Nexperia is an AEC-Q101-qualified NPN/PNP resistor-equipped double transistor (RET) in SOT363 (SC-88) package, integrating two matched bias resistors (R1 = R2 = 100 kΩ) per transistor. It delivers 50 V VCEO, 20 mA output current, and supports dual-polarity digital switching in space-constrained automotive and industrial control circuits.
For engineers reviewing the PUMD24 datasheet, PUMD24 pinout, PUMD24 application, or PUMD24 equivalent, this device serves as a drop-in replacement for discrete NPN+PNP pairs in level-shifting, IC input control, and low-current peripheral driver designs where board area and BOM count reduction are critical.
Technical Context
The PUMD24 integrates one NPN and one PNP transistor on a single die, each with built-in base bias resistors (R1 = 100 kΩ, R2 = 100 kΩ) enabling direct logic-level drive without external components. Its complementary topology allows push-pull or dual-rail signal conditioning in compact digital interface stages.
It operates across −65 °C to +150 °C ambient, with per-transistor power dissipation up to 200 mW and per-device total of 300 mW on FR4 PCB. Thermal resistance is 625 K/W (per transistor) and 416 K/W (per device), supporting reliable operation under transient loads in automotive ECUs and sensor modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage for both NPN and PNP transistors, defining safe operating range in 24 V automotive and industrial supply rails. |
| IO | 20 mA - Continuous output current per transistor, sufficient for driving LED indicators, small relays, or CMOS/TTL inputs. |
| R1 / R2 | 100 kΩ / 100 kΩ - Matched internal base bias resistors enabling direct 3.3 V/5 V logic interfacing without external pull-up/down networks. |
| hFE | 80 min - DC current gain at IC = 20 mA, VCE = 5 V (NPN), ensuring predictable saturation behavior in switching applications. |
| VCE(sat) | 150 mV max - Low saturation voltage at IC = 5 mA, IB = 0.25 mA, minimizing conduction loss in active-low/high output stages. |
| Ptot (device) | 300 mW - Total power dissipation limit on standard FR4 PCB, setting thermal design boundary for continuous dual-transistor operation. |
Pinout & Package
SOT363 (TSSOP6) plastic surface-mount package: 6-pin, 0.65 mm pitch, 2.1 mm × 1.25 mm × 0.95 mm body, optimized for high-density PCB layouts and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1 (NPN), referenced to system ground for low-side switching. |
| 2 | I1 | Base input for TR1 (NPN); accepts logic-high signal to turn on NPN output at Pin 6. |
| 3 | O2 | Collector output for TR2 (PNP); provides active-low sourcing when TR2 is enabled via Pin 5. |
| 4 | GND2 | Emiter connection for TR2 (PNP), tied to system ground for common-emitter PNP configuration. |
| 5 | I2 | Base input for TR2 (PNP); driven low (or negative relative to GND2) to activate PNP output at Pin 3. |
| 6 | O1 | Collector output for TR1 (NPN); provides active-high sinking path when TR1 is enabled via Pin 2. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors (R1 = R2 = 100 kΩ) | Eliminates need for four external resistors in dual-transistor logic interface, reducing layout area by >30% vs discrete solution. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD, enabling use in engine control and body electronics. |
| NPN/PNP complementarity | Enables bidirectional signal translation (e.g., 3.3 V ↔ 5 V) and complementary output stages without cross-coupling or timing skew. |
| Low VCE(sat) (150 mV max) | Reduces power loss and self-heating during sustained 20 mA switching, supporting stable operation at Tamb = 125 °C. |
Applications
| Automotive Door Module Control | Industrial PLC Input Conditioning |
|---|---|
|
Use Scenario: Driving window lift motor direction signals and mirror fold/unfold commands in door control units. IC Role / Device Role / Timing Role: Dual RET acts as level translator and current amplifier between microcontroller GPIOs and 12 V relay coils or MOSFET gates. Use Value: Reduces component count by 4 resistors per channel and enables compact 2.1 mm × 1.25 mm footprint in space-limited door modules. |
Use Scenario: Converting 24 V field sensor outputs to 3.3 V/5 V logic levels for PLC mainboard ADC or GPIO inputs. IC Role / Device Role / Timing Role: NPN side sinks 24 V sink-type sensor signals; PNP side sources 5 V pull-up for open-collector sensors. Use Value: Provides rail-to-rail compatibility with no external bias network, improving noise immunity and reducing BOM cost by $0.015/unit. |
| USB-C Port Power Switch Interface | Smart Home Sensor Hub Level Shifting |
|
Use Scenario: Controlling USB-C CC line pull-up/pull-down resistors during port negotiation in portable power banks. IC Role / Device Role / Timing Role: PNP switches 5 V CC pull-up; NPN switches GND-connected CC pull-down, synchronized by MCU GPIOs. Use Value: Enables fast, glitch-free CC line state changes with <100 ns propagation delay and eliminates resistor placement errors in fine-pitch layouts. |
Use Scenario: Interfacing Zigbee/Z-Wave SoCs (3.3 V I/O) with legacy 5 V analog sensors (e.g., temperature, humidity) in smart thermostats. IC Role / Device Role / Timing Role: NPN drives 5 V sensor enable lines; PNP pulls up I²C SDA/SCL lines to 5 V while maintaining 3.3 V logic compatibility. Use Value: Supports mixed-voltage I/O without dedicated level shifter ICs, cutting BoM cost and simplifying firmware timing constraints. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PUMB24 | PNP/PNP dual RET (no NPN element); identical R1/R2 values and SOT363 package. | Limited to dual-sourcing or dual-sinking topologies; cannot replace PUMD24 in push-pull or bidirectional interfaces. | Select only when circuit requires two PNP switches sharing common emitter and no NPN functionality is needed. |
| PUMH24 | NPN/NPN dual RET; same bias resistors and package but lacks PNP transistor. | Suitable for dual low-side switching only; cannot source current or interface with open-collector sensors requiring pull-up. | Choose when both outputs must sink current (e.g., LED matrix drivers), and no high-side or sourcing capability is required. |
Compared with PUMB24 and PUMH24, the PUMD24 uniquely combines NPN and PNP in one package-enabling true complementary output stages, bidirectional level shifting, and reduced interconnect complexity in mixed-signal automotive and industrial nodes.

FAQ
What is the maximum junction temperature rating for PUMD24?
The absolute maximum junction temperature (Tj) is 150 °C, validated per AEC-Q101 stress testing. Operation above this threshold risks permanent degradation of the integrated bias resistors and transistor gain. Derating curves in the datasheet show usable power drops linearly above 25 °C ambient, reaching zero at 150 °C junction.
Can PUMD24 be used in 3.3 V logic systems without level shifters?
Yes - its VI(on) is 1.5 V (typical) and VI(off) is 1.1 V (typical) for the NPN transistor, allowing direct interface with 3.3 V CMOS outputs. The PNP side requires a logic-low input (≤0.5 V) to activate, compatible with 3.3 V GPIOs configured as open-drain or actively pulled low.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio is tightly controlled at 0.8–1.2 (typical = 1.0), ensuring matched base current division between input and feedback paths. This maintains consistent hFE-independent biasing, stabilizing VCE(sat) across temperature and process variation - critical for predictable timing in synchronous control loops.
Is PUMD24 pin-compatible with other SOT363 RETs like PUMH24?
Yes - all Nexperia SOT363 RETs (PUMD24, PUMH24, PUMB24) share identical pinout: Pin 1 = GND1, Pin 2 = I1, Pin 3 = O2, Pin 4 = GND2, Pin 5 = I2, Pin 6 = O1. However, internal transistor types differ, so functional substitution requires verifying circuit polarity requirements before drop-in replacement.
