Product details
Overview
PUMD9-Q from Nexperia is an AEC-Q101-qualified NPN/PNP resistor-equipped double transistor (RET) in SOT363-3 (SC-88) package, rated for 50 V VCEO, 100 mA output current per transistor, with built-in bias resistors R1 = 10 kΩ and R2 = 47 kΩ. It serves as a compact, automotive-grade digital switching device for level translation and IC input control in space-constrained PCBs.
For engineers reviewing the PUMD9-Q datasheet, PUMD9-Q pinout, PUMD9-Q application, or PUMD9-Q equivalent, this device offers verified dual-polarity switching with integrated biasing-reducing external component count, simplifying layout, and supporting high-reliability automotive signal conditioning and load switching without discrete base resistors.
Technical Context
The PUMD9-Q integrates two complementary transistors-TR1 (NPN) and TR2 (PNP)-each with monolithically embedded bias networks. TR1 features hFE ≥ 100 at IC = 5 mA, VCE = 5 V; TR2 delivers comparable gain under negative polarity conditions with V(BR)CEO = 50 V and IC = −10 mA.
Its internal R1–R2 network enables direct logic-level drive: VI(on) = 0.8–1.4 V for TR1 and −0.8 to −1.4 V for TR2, while VI(off) remains ≤ ±0.7 V. Thermal resistance is 417 K/W (per device, FR4 PCB), supporting operation up to Tj = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 24 V automotive rail switching with margin. |
| IO | 100 mA - Continuous output current per transistor; sufficient for driving LED indicators, small relays, or logic inputs. |
| R1 | 10 kΩ ±30% - Integrated base-input resistor; eliminates need for external pull-up/down in standard TTL/CMOS interfacing. |
| R2/R1 ratio | 4.7 - Sets stable base current division; ensures consistent saturation across temperature (−40 °C to +150 °C). |
| fT (TR1) | 230 MHz - Transition frequency at VCE = 5 V, IC = 10 mA; enables fast digital switching up to ~10 MHz. |
| Ptot (device) | 300 mW - Total power dissipation at Tamb ≤ 25 °C on FR4; derates linearly above 25 °C per Fig. 1. |
| VCE(sat) | ≤ 100 mV at IC = 5 mA, IB = 0.25 mA - Low saturation voltage minimizes conduction loss in active switching. |
Pinout & Package
Package: SOT363-3 (TSSOP6), 1.3 mm × 2.2 mm × 0.95 mm, surface-mount plastic package with gull-wing leads and pin 1 index mark.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1 (NPN); common reference node for first transistor's current path. |
| 2 | I1 | Base input for TR1 (NPN); driven directly by 0–3.3 V/5 V logic without external resistor. |
| 3 | O2 | Collector output for TR2 (PNP); sinks current when TR2 is active (e.g., low-side switch control). |
| 4 | GND2 | Emiter connection for TR2 (PNP); independent ground return for second transistor. |
| 5 | I2 | Base input for TR2 (PNP); accepts negative-going or inverted logic signals for complementary switching. |
| 6 | O1 | Collector output for TR1 (NPN); sources current when TR1 is active (e.g., high-side interface to MCU inputs). |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Qualified for automotive applications per stress test standard; supports 15-year vehicle lifecycle reliability. |
| Integrated R1/R2 bias network | Eliminates 4 external resistors per pair; reduces BOM count and PCB footprint by >2 mm² vs. discrete BC847/BC857 solutions. |
| Dual-polarity topology (NPN+PNP) | Enables push-pull or complementary switching in single package; avoids cross-conduction risk in level-shifting circuits. |
| Low VCE(sat) and VI(on) | Ensures full logic-level compatibility with 1.8 V, 3.3 V, and 5 V MCUs without level shifters or additional drivers. |
| Thermal performance | Rth(j-a) = 417 K/W on FR4; allows sustained 100 mA operation at ambient ≤ 85 °C with no heatsink. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Input Conditioning |
|---|---|

|
Use Scenario: Controlling enable/disable sequencing of display backlight and audio amplifier rails. IC Role / Device Role / Timing Role: Complementary NPN/PNP pair managing staggered power-up timing between subsystems using shared GPIO. Use Value: Single-package solution prevents timing skew between high- and low-side control paths, improving system startup robustness. |
Use Scenario: Interfacing microcontroller PWM outputs to brushed DC motor H-bridge gate drivers. IC Role / Device Role / Timing Role: Logic-level translator and current booster ensuring clean gate turn-on/turn-off edges for MOSFET drivers. Use Value: 230 MHz fT supports PWM frequencies up to 10 MHz, enabling precise speed control without edge distortion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PUMH9-Q | NPN/NPN configuration; identical R1/R2 values and package; lacks PNP complement. | Suitable only where dual-NPN logic is required (e.g., open-collector bus termination), not for complementary switching. | Select when both outputs must source current or interface to wired-OR buses. |
| PUMB9-Q | PNP/PNP configuration; same bias network and thermal specs; no NPN element. | Applicable in dual-sinking topologies (e.g., negative-rail load control), but cannot replicate PUMD9-Q's push-pull behavior. | Choose for redundant sinking paths or negative-voltage domain interfaces only. |
Compared with PUMH9-Q and PUMB9-Q, the PUMD9-Q uniquely provides matched NPN+PNP functionality in one die-enabling true complementary switching, bidirectional level translation, and reduced interconnect complexity where both sourcing and sinking are required.

FAQ
What is the maximum operating junction temperature for PUMD9-Q?
The absolute maximum junction temperature (Tj) is 150 °C, as specified in Table 5. Operation at this limit requires strict thermal management: derate total power dissipation linearly above 25 °C ambient per Fig. 1, and ensure PCB copper area meets Nexperia's FR4 single-sided footprint guidelines (35 μm, tin-plated).
Can PUMD9-Q replace BC847B and BC857B in existing designs?
Yes-PUMD9-Q provides functional equivalence to BC847B (NPN) and BC857B (PNP) plus their four external bias resistors. Pin mapping differs (6-pin SOT363-3 vs. two SOT23s), so layout revision is required, but schematic netlist changes are minimal: connect I1/I2 to logic sources and O1/O2 to loads, with GND1/GND2 tied to local ground planes.
Is the R1/R2 ratio fixed or adjustable in PUMD9-Q?
The R1/R2 ratio is fixed at 4.7 (10 kΩ / 47 kΩ), with tolerance ±20% per Table 7. This ratio is laser-trimmed during wafer fabrication and cannot be modified externally. It is optimized for reliable saturation across automotive temperature ranges and standard logic voltage levels.
Does PUMD9-Q support 1.8 V logic input drive?
Yes-VI(on) is specified from 0.8 V (typical) to 1.4 V (max) for TR1 and −0.8 V to −1.4 V for TR2 at IC = 1 mA. At 1.8 V supply, the internal R1 ensures sufficient base current for full saturation, confirmed by Fig. 6 showing VI(on) < 1.2 V across −40 °C to +100 °C.
