Product details
Overview
PUMB11 from Nexperia is a PNP/PNP resistor-equipped double 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 dual digital switching element for low-current logic interfacing and peripheral control in space-constrained PCBs.
For engineers reviewing the PUMB11 datasheet, PUMB11 pinout, PUMB11 application, or PUMB11 equivalent, this device is selected for compact dual-PNP switching where built-in biasing eliminates external resistors, reduces BOM count, and supports fast digital signal translation in industrial I/O and microcontroller interface circuits.
Technical Context
The PUMB11 integrates two matched PNP transistors with monolithically embedded base bias networks-each featuring R1 = 10 kΩ (input resistor) and R2 = 10 kΩ (feedback resistor), yielding an R2/R1 ratio of 1.0. Its dual-emitter-grounded topology enables independent control of both transistors while sharing thermal and layout symmetry.
Designed for DC-coupled digital switching-not linear amplification-it operates with guaranteed VI(on) = −1.8 V (typ.) at IC = −10 mA and VCE(sat) ≤ −100 mV under IC/IB = 20, supporting reliable TTL/CMOS-level input compatibility and low-loss output drive.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage with open base; defines off-state blocking capability in digital switch applications. |
| IO | −100 mA per transistor: Continuous DC output current rating; supports driving LEDs, small relays, or logic inputs without external current limiting. |
| R1 | 10 kΩ (7–13 kΩ): Integrated input bias resistor; sets base current for predictable turn-on without discrete components. |
| R2/R1 | 1.0 (0.8–1.2): Matched feedback-to-input resistor ratio; stabilizes operating point against temperature and process variation. |
| VCE(sat) | ≤ −100 mV at IC = −10 mA, IB = −0.5 mA: Low saturation voltage ensures minimal power loss and high logic-low fidelity in switching mode. |
| fT | 180 MHz (typ.): Transition frequency confirms suitability for digital signals up to ~10–20 MHz edge rates without significant delay distortion. |
| Ptot (per device) | 300 mW at Tamb = 25 °C on FR4 PCB: Total dissipation limit determines maximum simultaneous switching duty across both transistors. |
Pinout & Package
SOT363-3 (SC-88/TSSOP6) is a 6-pin, 2.2 mm × 1.35 mm surface-mount plastic package with gull-wing leads and exposed pad-compatible footprint. Pin 1 is marked by index notch or dot; device orientation follows standard transparent top view.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emitter connection of TR1; common reference node for first transistor's current path. |
| 2 | I1 | Base input of TR1; accepts logic-level voltage (e.g., MCU GPIO) through internal R1. |
| 3 | O2 | Collector output of TR2; active-low switched output tied to load (e.g., LED cathode). |
| 4 | GND2 | Emitter connection of TR2; independent ground return for second transistor. |
| 5 | I2 | Base input of TR2; electrically isolated from I1 but identical bias network structure. |
| 6 | O1 | Collector output of TR1; primary switched output used in complementary pair configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Dual PNP RET architecture | Two fully independent PNP transistors with matched R1/R2 networks enable synchronous or separate digital control without cross-talk. |
| Integrated 10 kΩ bias resistors | Eliminates four external resistors per device, reducing PCB area by ≥1.5 mm² and eliminating solder joint reliability risks. |
| −100 mV VCE(sat) @ IC = −10 mA | Ensures <0.5 mW conduction loss per transistor, critical for battery-powered or thermally constrained I/O expansion modules. |
| 180 MHz fT | Supports clean switching of 5–10 MHz clocked control signals (e.g., SPI chip selects, PWM dimming) without rise/fall time degradation. |
| −50 V VCEO rating | Allows direct interface with 24 V industrial control rails or 3.3/5 V logic with margin against transient overshoot. |
Applications
| Industrial I/O Expansion | Microcontroller GPIO Buffering |
|---|---|
|
Use Scenario: Driving optocoupler inputs or 24 V PLC input modules from 3.3 V microcontrollers. IC Role / Device Role / Timing Role: Dual PNP level shifter and current amplifier; each transistor switches one channel independently. Use Value: Eliminates need for discrete base resistors and pull-up networks, cutting BOM cost by $0.015/unit and reducing layout complexity. |
Use Scenario: Isolating and strengthening weak MCU GPIO outputs controlling LED indicators or small solenoids. IC Role / Device Role / Timing Role: Active-low digital buffer with built-in biasing; provides 100 mA sink capability per channel. Use Value: Enables direct drive of 20 mA LEDs without external components, reducing layer count and assembly steps in wearable sensor nodes. |
| Low-Power Sensor Interface | Digital Logic Translation |
|
Use Scenario: Enabling/disabling analog sensor power rails using MCU-controlled PNP switches. IC Role / Device Role / Timing Role: Dual high-side switch controller; GND1/GND2 tied to system ground, O1/O2 connected to sensor VCC lines. Use Value: Achieves <1 µA shutdown leakage (ICEO ≤ −5 µA at 150 °C), extending battery life in remote environmental monitors. |
Use Scenario: Converting 1.8 V LVTTL logic outputs to −5 V compatible levels for legacy industrial bus receivers. IC Role / Device Role / Timing Role: Inverting level translator with fixed gain; VI(on)/VI(off) thresholds ensure noise-immune switching at 100 kHz data rates. Use Value: Delivers consistent −1.8 V turn-on threshold across −40 to +100 °C, avoiding timing skew in multi-channel serial interfaces. |
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 | NPN/PNP complement; single NPN + single PNP pair instead of PNP/PNP; R1 = 10 kΩ, R2 = 10 kΩ, same package. | Required where one channel needs sourcing (NPN) and another sinking (PNP); not suitable for dual-sink or dual-high-side use cases. | Select when mixed polarity drive is needed-e.g., half-H-bridge pre-driver or bidirectional level shifters. |
| PUMH11 | NPN/NPN version; identical R1/R2 values and SOT363-3 package; VCEO = 50 V, IO = 100 mA. | Used where both channels must source current (e.g., driving NMOS gates or active-high logic loads); lacks high-side switching capability. | Choose for dual low-side switch applications with positive logic control, especially in 3.3 V/5 V digital systems. |
Compared with PUMD3 and PUMH11, PUMB11 uniquely supports dual high-side or dual active-low configurations with matched PNP characteristics, making it optimal for redundant I/O buffering, dual-channel LED matrix row drivers, and fail-safe shutdown circuits requiring symmetrical negative-rail switching.

FAQ
What is the maximum continuous current per transistor in PUMB11?
The PUMB11 is rated for −100 mA continuous output current per transistor under Tamb ≤ 25 °C with proper PCB copper area. Derating applies above 25 °C per the 417 K/W per-device thermal resistance; at 70 °C ambient, max current drops to approximately −65 mA to maintain Tj ≤ 150 °C.
Can PUMB11 be used in linear amplifier mode?
No-PUMB11 is characterized and qualified exclusively for digital switching operation. Its built-in resistors fix the base bias point, and parameters like hFE and VCE(sat) are specified only under saturated switching conditions. Linear gain is neither guaranteed nor tested per datasheet.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 1.0 (±0.2) ensures stable base current division and prevents latch-up during fast transitions. A ratio near unity minimizes sensitivity to process variation, maintaining consistent VI(on) and VI(off) thresholds across temperature and voltage-critical for noise-immune digital interfacing.
Is PUMB11 automotive-qualified?
No-PUMB11 is not automotive-qualified. The datasheet explicitly states "Non-automotive qualified products" in Section 15, and no AEC-Q101 stress test data or automotive-grade screening is included. It is intended for industrial, consumer, and computing applications only.
