Product details
Overview
PUMB11-Q from Nexperia is a dual PNP resistor-equipped transistor (RET) in SOT363-3 (SC-88) package, rated for −50 V VCEO, −100 mA output current per transistor, with integrated 10 kΩ input bias resistors (R1 = R2 = 10 kΩ). It functions as a compact, AEC-Q101-qualified digital switching pair for low-current peripheral driving and IC input control in space-constrained automotive and industrial PCBs.
For engineers reviewing the PUMB11-Q datasheet, PUMB11-Q pinout, PUMB11-Q application, or PUMB11-Q equivalent, this page delivers verified electrical parameters, validated dual-transistor pin mapping, automotive-grade thermal derating curves, and direct alternatives for discrete logic-level interface consolidation.
Technical Context
The PUMB11-Q integrates two matched PNP transistors with on-die base bias networks-each featuring R1 = 10 kΩ (input resistor) and R2 = 10 kΩ (feedback resistor), yielding an R2/R1 ratio of 1.0 (±0.2). Its dual-emitter-grounded topology supports independent switching of two loads referenced to common ground.
It operates under −50 V collector-emitter breakdown voltage and −10 V emitter-base rating, with guaranteed hFE ≥ 30 at −5 mA IC, −5 V VCE, and VCE(sat) ≤ −100 mV at −10 mA IC/−0.5 mA IB. Thermal resistance is 417 K/W (per device, 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 automotive supply rails with margin. |
| IO | −100 mA - Continuous DC output current per transistor; sufficient for LED drivers, relay coils, and logic-level MOSFET gate control. |
| R1 / R2 | 10 kΩ / 10 kΩ - Integrated base bias resistors eliminate external components; reduces BOM count and layout area by ~4 passives per channel. |
| hFE | ≥30 - Minimum DC current gain at −5 mA IC; ensures reliable saturation with standard microcontroller GPIO drive (e.g., 3.3 V/5 V logic). |
| VCE(sat) | ≤ −100 mV - Low saturation voltage at −10 mA IC/−0.5 mA IB; minimizes power loss and self-heating in high-duty-cycle switching. |
| Ptot (device) | 300 mW @ Tamb = 25 °C - Total power dissipation limit on FR4 PCB; supports sustained operation up to ~85 °C ambient with derating. |
Pinout & Package
SOT363-3 (SC-88) 6-pin TSSOP package: 1.3 mm × 2.2 mm footprint, 0.65 mm pitch, 0.45 mm max height; optimized for reflow soldering with defined land pattern (2.65 mm × 2.35 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1; provides local ground reference and thermal path for first transistor. |
| 2 | I1 | Base input for TR1; internally connected to R1 (10 kΩ) - accepts TTL/CMOS logic-level signals directly. |
| 3 | O2 | Collector output for TR2; active-low switching node - sinks current when TR2 is biased on. |
| 4 | GND2 | Emiter connection for TR2; independent ground terminal enabling dual-load isolation or split grounding. |
| 5 | I2 | Base input for TR2; identical bias network to I1 - allows synchronous or independent control of second channel. |
| 6 | O1 | Collector output for TR1; complements O2 for dual-sink configuration - supports parallel or cascaded logic interfacing. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Stress-tested to automotive reliability standards; suitable for under-hood and body-control modules without additional qualification. |
| Dual PNP RET architecture | Two fully independent PNP switches with matched R1/R2 networks - eliminates need for 4 external resistors and simplifies routing. |
| Low VCE(sat) | ≤ −100 mV ensures <10 mW conduction loss at 100 mA - critical for thermally constrained modules and battery-powered systems. |
| High VCEO rating | −50 V withstand capability supports 24 V nominal systems with load-dump immunity (ISO 7637-2 Pulse 5a) when used with clamping. |
| Small-outline SOT363-3 | 1.3 × 2.2 mm footprint saves >60% board area vs. SO-8 discrete pairs - ideal for wearables, sensor nodes, and compact ECUs. |
Applications
| Automotive Body Control Module | Industrial PLC Input Conditioning |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-PNP switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PUMD3-Q | NPN/PNP complement - single NPN + single PNP channel; R1 = 10 kΩ, R2 = 10 kΩ; same package. | Required where mixed-signal level translation (e.g., 5 V → 3.3 V pull-up + pull-down) is needed. | Select when circuit requires one sourcing and one sinking channel in same footprint. |
| PUMH11-Q | NPN/NPN version - both channels NPN; identical R1/R2 values and SOT363-3 package. | Used where active-high drive (e.g., NMOS gate control, LED anode switching) dominates the design. | Choose for designs relying on low-side switching only and requiring consistent NPN behavior across both channels. |
Compared with PUMD3-Q and PUMH11-Q, the PUMB11-Q uniquely delivers matched dual-PNP behavior - essential for complementary load control in grounded-emitter configurations, such as dual LED cathode drivers or redundant safety interlocks requiring identical turn-on thresholds.

FAQ
What is the maximum operating temperature for PUMB11-Q in continuous use?
The PUMB11-Q has a maximum junction temperature (Tj) of 150 °C and specified ambient operating range of −65 °C to +150 °C. On a standard FR4 PCB, its power derating curve shows usable dissipation down to 0 mW at 125 °C ambient - confirming suitability for under-dash automotive environments with proper thermal layout.
Can PUMB11-Q be used with 3.3 V microcontroller GPIOs?
Yes. With VI(on) = −1.8 V (typical) at −10 mA IC, the PUMB11-Q reliably saturates when driven by 3.3 V GPIOs through a series resistor or directly - its −1.1 V to −0.8 V VI(off) threshold ensures solid cutoff with 0 V logic low, eliminating unintended conduction.
Is there crosstalk between the two transistors inside PUMB11-Q?
No measurable functional crosstalk exists. Electrical isolation between TR1 and TR2 is maintained via separate emitter terminals (GND1/GND2) and independent base-collector paths. Characterization data shows no coupling in switching waveforms or leakage (<100 nA ICBO) under worst-case bias conditions.
How does the built-in resistor network affect switching speed?
The 10 kΩ R1 resistors limit base charging current, resulting in ton ≈ 150 ns and toff ≈ 80 ns (typical at IC = −50 mA). This is adequate for <500 kHz digital switching but not for RF or high-speed PWM; external base resistors are unnecessary but may be added to fine-tune speed if required.
