Product details
Overview
PUMB2-Q from Nexperia is a PNP/PNP resistor-equipped double transistor (RET) in SOT363-3 (SC-88) package, rated for −50 V VCEO, −100 mA IO, with built-in 47 kΩ input bias resistors (R1 = R2), qualified to AEC-Q101 for automotive signal-level switching and digital interface control.
For engineers reviewing the PUMB2-Q datasheet, PUMB2-Q pinout, PUMB2-Q application, or PUMB2-Q equivalent, this device serves as a space-optimized, bias-resistor-integrated dual PNP switch for low-current peripheral drivers, IC input control, and discrete logic-level translation in constrained PCB layouts.
Technical Context
This dual RET integrates two matched PNP transistors with monolithically embedded base bias networks-each with R1 = 47 kΩ and R2/R1 ratio = 1.0-enabling direct TTL/CMOS-compatible input drive without external resistors. The configuration supports independent or cascaded switching topologies.
It operates within −65 °C to +150 °C ambient range, delivers hFE ≥ 80 at −5 V VCE and −5 mA IC, and achieves VCE(sat) ≤ −150 mV at −10 mA IC/−0.5 mA IB, ensuring low-loss switching in battery-powered and automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage with open base; enables use in 24 V automotive supply rails with margin. |
| IO | −100 mA: Continuous output current per transistor; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 / R2 | 47 kΩ / 47 kΩ: Integrated base bias resistors eliminate two external components per channel, reducing BOM count and layout area. |
| hFE | ≥ 80 at −5 V VCE, −5 mA IC: Ensures reliable saturation with modest input drive, supporting direct microcontroller GPIO interfacing. |
| VCE(sat) | ≤ −150 mV at −10 mA IC, −0.5 mA IB: Minimizes conduction loss and self-heating in always-on or pulsed control circuits. |
| AEC-Q101 | Qualified: Meets stress-test requirements for automotive discrete semiconductors, supporting under-hood and body-control module deployment. |
Pinout & Package
SOT363-3 (SC-88/TSSOP6) plastic surface-mounted package: 2.2 mm × 1.35 mm footprint, 0.65 mm pitch, 0.95 mm max height, optimized for high-density routing and reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter of TR1; common reference node for first transistor's current path. |
| 2 | I1 | Base input of TR1; accepts logic-level signals directly due to integrated R1 bias network. |
| 3 | O2 | Collector of TR2; active-low output node for second transistor's switched load. |
| 4 | GND2 | Emiter of TR2; independent ground return for second transistor, enabling isolated dual-channel operation. |
| 5 | I2 | Base input of TR2; electrically identical to I1, supporting synchronous or independent control. |
| 6 | O1 | Collector of TR1; primary active-low output, paired with O2 for complementary or cascaded switching. |
Key Features
| Feature | Design Value |
|---|---|
| Dual PNP RET architecture | Two functionally independent PNP transistors with matched internal biasing, enabling compact dual-channel switching without inter-channel coupling. |
| Integrated 47 kΩ bias resistors | Eliminates need for four external base resistors, reducing component count by ≥66% versus discrete transistor + resistor solutions. |
| AEC-Q101 qualification | Validated for automotive applications including body electronics, lighting controls, and sensor interface modules requiring extended temperature and reliability compliance. |
| Low VCE(sat) (≤ −150 mV) | Reduces power dissipation in high-duty-cycle switching, extending thermal margin on FR4 PCBs with standard copper thickness. |
Applications
| Automotive Door Module Control | Industrial PLC Input Conditioning |
|---|---|
|
Use Scenario: Driving window lift motor enable lines and mirror fold/unfold signals in vehicle door modules.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual PNP resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PUMH2-Q | NPN/NPN complement; same package, R1 = R2 = 47 kΩ, but opposite polarity and forward-biased operation. | Required where active-high switching or sourcing (vs. sinking) is needed; incompatible for direct replacement in PNP-biased circuits. | Select when designing NPN-driven loads or complementary push-pull stages requiring matched RET characteristics. |
| PUMD12-Q | NPN/PNP complement; mixed polarity pair in same SOT363-3 package, with R1 = 22 kΩ, R2 = 47 kΩ. | Enables level-shifting between positive- and negative-rail domains in single-package form; not interchangeable in dual-PNP-only topologies. | Choose for bidirectional interface circuits such as I²C bus voltage translation or mixed-signal gate driving. |
Compared with PUMH2-Q and PUMD12-Q, PUMB2-Q uniquely provides matched dual-PNP functionality with symmetric 47 kΩ biasing-critical for redundant control paths, mirrored signal conditioning, or fail-safe automotive subsystems requiring consistent sinking behavior across both channels.

FAQ
What is the maximum junction temperature and how does it affect continuous operation?
The absolute maximum junction temperature is 150 °C. At ambient temperatures up to 85 °C, the device sustains full −100 mA per transistor with appropriate PCB copper area (FR4, 35 μm, single-sided). Derating begins above 25 °C ambient, reaching 0 mW at 150 °C junction per the 417 K/W per-device thermal resistance curve.
Can PUMB2-Q be used in linear amplifier configurations?
No-it is designed and characterized exclusively for switching operation. Its hFE variation across collector current (Fig. 3), lack of linear-region specifications, and absence of small-signal parameters (e.g., fT guaranteed in linear mode) confirm its intended use as a saturated switch, not an analog amplifier.
How are the built-in resistors tested and what tolerance applies?
Resistors are measured per Table 8 test conditions: R1 = 47 kΩ (33–61 kΩ min–max), R2/R1 = 1.0 (0.8–1.2). Testing uses −55 μA and −105 μA bias currents per transistor, verified during AEC-Q101 qualification. Tolerance reflects process variation-not user-adjustable trim.
Is there crosstalk between the two transistors inside the SOT363-3 package?
No measurable electrical crosstalk occurs: each transistor has fully isolated emitter (GND1/GND2), collector (O1/O2), and base (I1/I2) terminals. Thermal coupling exists but remains within spec limits-junction temperature rise is modeled per-device using 417 K/W Rth(j-a) for the full package.
