Product details
Overview
PUMD9/ZLX from Nexperia is a resistor-equipped double transistor (RET) integrating one NPN and one PNP bipolar junction transistor in a single SOT363-3 (TSSOP6) package, with built-in bias resistors R1 = 10 kΩ and R2 = 47 kΩ, rated for 50 V VCEO, 100 mA output current per transistor, and optimized for digital switching in automotive and industrial control circuits.
For engineers reviewing the PUMD9/ZLX datasheet, PUMD9/ZLX pinout, PUMD9/ZLX application, or PUMD9/ZLX equivalent, this device serves as a space- and BOM-saving alternative to discrete BC847/BC857 pairs in level-shifting, IC input control, and low-power load switching where integrated biasing simplifies drive logic and reduces PCB footprint.
Technical Context
The PUMD9/ZLX implements a dual-transistor topology with TR1 (NPN) and TR2 (PNP) sharing no internal connection except common ground terminals-each transistor operates independently with its own dedicated base bias network. TR1 exhibits fT = 230 MHz and hFE ≥ 100 at IC = 5 mA, while TR2 delivers fT = 180 MHz and comparable DC gain under negative-polarity conditions.
Its resistor-equipped architecture eliminates external base resistors: R1 sets input current sensitivity (90 µA typical at TR1 input), and R2/R1 = 4.7 defines the internal feedback ratio, enabling direct TTL/CMOS-compatible drive without additional components. Thermal resistance is 417 K/W (per device, FR4 PCB), supporting continuous operation up to Tj = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V industrial bus and 12 V automotive domains. |
| IO | 100 mA - Continuous output current per transistor; sufficient for driving LEDs, small relays, and logic inputs. |
| R1 | 10 kΩ ±30% - Integrated input bias resistor; sets nominal base current of 90 µA at 1 V input, reducing external component count. |
| R2/R1 | 4.7 - Fixed internal resistor ratio; determines saturation behavior and improves noise immunity during switching transitions. |
| Ptot (device) | 300 mW at Tamb ≤ 25 °C - Total power dissipation limit on standard FR4 PCB; supports dual-transistor operation without forced cooling. |
| fT (TR1) | 230 MHz - Transition frequency of NPN transistor; ensures reliable switching up to ~10 MHz digital signal rates. |
| VCE(sat) | 100 mV max at IC = 5 mA, IB = 0.25 mA - Low saturation voltage minimizes conduction loss and heat generation in active-switching mode. |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mounted package: 1.3 mm × 2.2 mm footprint, 0.65 mm pitch, 0.95 mm max height, designed for reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emitter terminal of TR1 (NPN); provides low-impedance return path and thermal sink for first transistor. |
| 2 | I1 | Base input of TR1 (NPN); accepts logic-level signals directly due to integrated R1 bias network. |
| 3 | O2 | Collector output of TR2 (PNP); active-low switching node with 50 V rating and 100 mA capability. |
| 4 | GND2 | Emitter terminal of TR2 (PNP); independent ground reference enabling dual-rail or floating load configurations. |
| 5 | I2 | Base input of TR2 (PNP); compatible with negative-going or open-collector drive sources. |
| 6 | O1 | Collector output of TR1 (NPN); active-high switching node used for sourcing current to loads or pull-up networks. |
Key Features
| Feature | Design Value |
|---|---|
| Dual complementary topology | NPN + PNP pairing enables push-pull, level translation, and bidirectional signal conditioning without external polarity inversion. |
| Integrated bias network | R1 = 10 kΩ and R2 = 47 kΩ eliminate two external resistors per transistor, cutting BOM count by 4 parts per device. |
| Low VCE(sat) | ≤100 mV ensures <10 mW conduction loss at 100 mA, reducing thermal stress and improving efficiency in battery-powered systems. |
| High fT performance | 230 MHz (TR1) and 180 MHz (TR2) support clean edge integrity in digital clock distribution and fast GPIO toggling. |
| Automotive-grade reliability | Rated for Tamb = −65 °C to +150 °C and qualified per AEC-Q101; suitable for under-hood and engine-control module applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar resistor-equipped double transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PUMH9 | NPN/NPN configuration only; lacks PNP complement; identical R1/R2 values and SOT363-3 package. | Restricted to dual-sourcing or parallel-drive topologies; cannot replace PUMD9 in push-pull or level-reversal circuits. | Select when both outputs require NPN logic polarity and shared emitter grounding suffices. |
| PUMB9 | PNP/PNP configuration only; no NPN element; same bias resistor values and thermal specs. | Only suitable for dual-sinking or negative-rail switching; incompatible with high-side load control. | Choose for applications needing two independent low-side switches with matched VCEO and IO. |
Compared with PUMH9 and PUMB9, the PUMD9/ZLX uniquely delivers true complementary NPN+PNP functionality in one die, enabling bidirectional signal control, reduced interconnect complexity, and elimination of cross-coupling components in mixed-polarity interfaces.

FAQ
What is the maximum operating temperature for PUMD9/ZLX?
The PUMD9/ZLX has a maximum junction temperature (Tj) of 150 °C and an ambient operating range of −65 °C to +150 °C. Its thermal resistance is 417 K/W (per device on FR4 PCB), allowing full 100 mA output current at Tamb ≤ 85 °C with no derating. Derating begins linearly above 85 °C per Figure 1 in the datasheet.
Can PUMD9/ZLX replace BC847 and BC857 transistors in existing designs?
Yes-PUMD9/ZLX serves as a drop-in functional replacement for BC847 (NPN) and BC857 (PNP) pairs in digital switching applications. It integrates matching bias resistors (R1 = 10 kΩ, R2 = 47 kΩ), occupies the same SOT363-3 footprint, and maintains identical VCEO (50 V) and IO (100 mA) ratings, eliminating four external resistors and two packages.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 = 4.7 ratio establishes the internal feedback path that stabilizes base current and improves saturation depth. At IC = 5 mA, it ensures IB/IC ≈ 0.05, delivering guaranteed VCE(sat) ≤ 100 mV. This ratio also raises the effective VI(on) threshold to 0.8 V (min), enhancing noise margin against false triggering in noisy environments.
Is PUMD9/ZLX qualified for automotive applications?
Yes-PUMD9/ZLX is AEC-Q101 qualified and rated for operation from −65 °C to +150 °C. It meets automotive reliability requirements for body electronics, lighting control, and infotainment subsystems. The datasheet explicitly states qualification status and includes automotive-grade test data for hFE, VCE(sat), and leakage across temperature.
