Product details
Overview
PUMD2/ZLZ from Nexperia is an NPN/PNP dual resistor-equipped transistor (RET) in a SOT363 (SC-88) surface-mount package, integrating two complementary bias-resistor-transistors - one NPN and one PNP - each with 22 kΩ input bias resistors (R1 = R2 = 22 kΩ). It delivers 100 mA output current per transistor, supports ±50 V collector-emitter voltage, and is AEC-Q101 qualified for automotive use in level-shifting, logic interfacing, and peripheral driver circuits.
For engineers reviewing the PUMD2/ZLZ datasheet, PUMD2/ZLZ pinout, PUMD2/ZLZ application, or PUMD2/ZLZ equivalent, this page provides verified pin functions, thermal derating curves, DC current gain (hFE ≥ 60), saturation voltage (VCEsat ≤ 150 mV), and bias resistor tolerance (±30%) - all critical for digital switching, I/O buffering, and space-constrained PCB designs.
Technical Context
The PUMD2/ZLZ integrates two monolithic transistors - TR1 (NPN) and TR2 (PNP) - sharing no internal connection other than common GND terminals. Each includes built-in base-emitter and base-collector bias resistors (R1 = 22 kΩ, R2 = 22 kΩ), eliminating external components for basic switching configurations.
TR1 exhibits fT = 230 MHz and hFE ≥ 60 at IC = 5 mA, while TR2 delivers fT = 180 MHz and comparable gain under negative-polarity biasing. Both transistors operate across −55 °C to +150 °C ambient, with thermal resistance Rth(j-a) = 417 K/W per device on FR4 PCB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V industrial control rails. |
| IO | 100 mA - Continuous output current per transistor; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 / R2 | 22 kΩ ±30% - Integrated base bias resistors reduce BOM count and eliminate manual resistor placement. |
| hFE | ≥60 at IC = 5 mA - Ensures reliable saturation with low base drive current (IB ≈ 83 µA typical). |
| VCEsat | ≤150 mV at IC = 10 mA, IB = 0.5 mA - Minimizes power loss and self-heating in high-duty-cycle switching. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HAST, and ESD testing. |
| Ptot (per device) | 300 mW at Tamb ≤ 25 °C - Defines maximum dissipation before thermal derating begins; matches SOT363 footprint limits. |
Pinout & Package
SOT363 (SC-88) ultra-small 6-pin surface-mount plastic package with 0.65 mm pitch; dimensions 2.2 × 1.35 × 0.95 mm (L × W × H); moisture sensitivity level (MSL) 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND (emitter) TR1 | Common emitter reference for NPN transistor; connects to system ground or low-side return path. |
| 2 | input (base) TR1 | Driven input node for NPN transistor; internally connected to R1 and R2 network for self-biasing. |
| 3 | output (collector) TR2 | Active-high output terminal of PNP transistor; sinks current when TR2 is on. |
| 4 | GND (emitter) TR2 | Common emitter reference for PNP transistor; tied to system ground or shared with Pin 1 in dual-GND configuration. |
| 5 | input (base) TR2 | Driven input node for PNP transistor; polarity-sensitive - requires negative-going signal relative to emitter. |
| 6 | output (collector) TR1 | Active-low output terminal of NPN transistor; sources current when TR1 is on (via external pull-up). |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN/PNP RET topology | Enables complementary push-pull or level-shifted outputs without discrete bias networks. |
| Integrated R1/R2 = 22 kΩ | Reduces component count by two resistors per channel and eliminates pick-and-place steps for biasing. |
| 100 mA per transistor rating | Supports direct interface to microcontroller GPIOs, optocoupler inputs, and small-signal loads. |
| AEC-Q101 qualification | Validates suitability for under-hood automotive modules, body control units, and ADAS sensor interfaces. |
| SOT363 footprint | Occupies only 2.97 mm² board area - ideal for wearables, compact IoT nodes, and multi-channel sensor hubs. |
Applications
| Automotive Door Module | Industrial PLC Input Stage |
|---|---|
Use Scenario: Level-shifting and isolation between 3.3 V MCU GPIOs and 24 V field sensors in door latch position detection. IC Role / Device Role / Timing Role: Dual RET acts as bidirectional signal conditioner - NPN switches 24 V pull-down, PNP drives 3.3 V open-drain feedback. Use Value: Eliminates four external resistors and two transistors per channel, reducing layout area by 35% and improving ESD robustness via integrated bias network. |
Use Scenario: Converting 24 V dry-contact inputs into clean 5 V logic signals for PLC main controller. IC Role / Device Role / Timing Role: PNP side accepts 24 V input; NPN side outputs active-low 5 V logic compatible with FPGA or ARM GPIO. Use Value: Built-in 22 kΩ bias resistors ensure stable turn-on/turn-off thresholds across temperature, avoiding false triggers in noisy factory environments. |
| USB-C Power Delivery Interface | Smart Home Sensor Hub |
Use Scenario: Managing CC line voltage translation and fault signaling between USB-C port controller and PD policy engine. IC Role / Device Role / Timing Role: NPN handles sink-mode CC line pull-down; PNP manages source-mode VCONN enable/disable sequencing. Use Value: Matched R1/R2 ratio (0.8–1.2) ensures symmetrical rise/fall times (<100 ns), meeting USB-C timing compliance for hot-plug detection. |
Use Scenario: Driving multiple low-power environmental sensors (e.g., PIR, humidity, CO₂) from a single 3.3 V SoC with minimal external components. IC Role / Device Role / Timing Role: One PUMD2/ZLZ per sensor channel provides buffered enable/control with independent NPN/PNP logic states. Use Value: 150 °C max junction temperature and 100 nA ICEO support long-term operation in sealed enclosures without forced cooling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual RET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSVD2T114FR | R1 = 10 kΩ, R2 = 10 kΩ; SOT-563 package; lower VCEO (40 V); same AEC-Q101 grade. | Better suited for 12 V systems with tighter board space; not recommended for 24 V industrial rails due to reduced voltage margin. | Select when lower input impedance is needed for faster switching or when SOT-563 footprint aligns with existing layout. |
| EMX11T2R | NPN/NPN dual RET; R1 = 47 kΩ, R2 = 47 kΩ; SOT-363; no PNP element; higher VCEO (60 V). | Lacks complementary output capability - cannot replace PUMD2/ZLZ in push-pull or level-shift topologies requiring both polarities. | Choose only for unidirectional high-side switching where dual NPN functionality suffices and 60 V rating is required. |
Compared with NSVD2T114FR and EMX11T2R, PUMD2/ZLZ uniquely combines NPN+PNP complementarity, 50 V rating, and matched 22 kΩ biasing in SOT363 - making it the only option for compact, bipolar digital interfacing in automotive and industrial 24 V domains.

FAQ
What is the maximum operating temperature for PUMD2/ZLZ?
The PUMD2/ZLZ has a maximum junction temperature (Tj) of 150 °C and operates across an ambient range of −55 °C to +150 °C. Its thermal resistance Rth(j-a) is 417 K/W per device on standard FR4 PCB, meaning it dissipates up to 300 mW at 25 °C ambient before derating begins - critical for sealed automotive enclosures.
Can PUMD2/ZLZ replace discrete transistors and resistors in existing designs?
Yes - PUMD2/ZLZ replaces two transistors and four resistors (two base-emitter and two base-collector) in standard RET configurations. Its pinout matches industry-standard SOT363 layouts, and its 22 kΩ bias resistors match common digital logic drive requirements, enabling drop-in replacement without schematic or layout changes in most cases.
Is PUMD2/ZLZ suitable for analog amplification?
No - PUMD2/ZLZ is optimized for digital switching, not linear amplification. Its integrated bias resistors fix the DC operating point, and its hFE variation (60–200) and limited fT bandwidth make it unsuitable for precision analog gain stages. Use dedicated general-purpose transistors like BC847 for amplification.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 0.8–1.2 ensures balanced base current distribution between input and feedback paths, stabilizing turn-on/turn-off thresholds against process variation. This tight ratio prevents latch-up in CMOS-driven configurations and maintains consistent VI(on)/VI(off) voltages (1.7–2.5 V / 0.8–1.1 V) across temperature and voltage rails.
