Product details
Overview
PUMB2F 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 integrated 47 kΩ bias resistors R1 and R2 per transistor. It functions as a dual low-side switch or digital interface buffer in space-constrained automotive and industrial control circuits.
For engineers reviewing the PUMB2F datasheet, PUMB2F pinout, PUMB2F application, or PUMB2F equivalent, this device is selected for compact dual-transistor logic-level interfacing where built-in biasing eliminates external resistors, reduces BOM count, and supports AEC-Q101-compliant automotive signal conditioning.
Technical Context
The PUMB2F integrates two matched PNP transistors with monolithically embedded base bias networks-each with R1 = 47 kΩ (input resistor) and R2 = 47 kΩ (feedback resistor), yielding R2/R1 = 1.0. Its dual-emitter-grounded topology enables independent switching of two loads referenced to common ground.
It operates within −65 °C to +150 °C ambient range, with per-transistor power dissipation limited to 200 mW (FR4 PCB, 25 °C), and junction temperature capped at 150 °C. The device exhibits hFE ≥ 80 at −5 V VCE, −5 mA IC, and VCE(sat) ≤ −150 mV at −10 mA IC/−0.5 mA IB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum collector-emitter voltage before breakdown; defines safe operating voltage for driving 24 V automotive loads with margin. |
| IO | −100 mA - Continuous output current per transistor; supports direct drive of LEDs, small relays, or logic inputs without external current gain staging. |
| R1 / R2 | 47 kΩ / 47 kΩ - Integrated base bias resistors eliminate need for 4 external resistors in dual-transistor logic buffer design. |
| hFE | ≥ 80 - DC current gain at −5 V VCE, −5 mA IC; ensures reliable saturation with microcontroller GPIO-level base drive (e.g., 3.3 V/5 V logic). |
| VCE(sat) | ≤ −150 mV - Low saturation voltage at −10 mA IC/−0.5 mA IB; minimizes power loss and heat generation in high-duty-cycle switching. |
| AEC-Q101 | Qualified - Meets stress-test requirements for discrete semiconductors in automotive applications; supports under-hood and body-control module use. |
Pinout & Package
SOT363-3 (SC-88) 6-pin TSSOP package: ultra-compact surface-mount outline (2.2 mm × 1.35 mm × 0.95 mm), optimized for high-density PCB layouts and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emitter connection of transistor TR1; provides local ground reference for first channel. |
| 2 | I1 | Base input of TR1; accepts logic-level signal (e.g., MCU GPIO) through internal R1 resistor. |
| 3 | O2 | Collector output of TR2; sinks current from load connected between VCC and O2. |
| 4 | GND2 | Emitter connection of transistor TR2; independent ground path for second channel. |
| 5 | I2 | Base input of TR2; electrically isolated from I1, enabling independent control of both transistors. |
| 6 | O1 | Collector output of TR1; sinks current from load connected between VCC and O1. |
Key Features
| Feature | Design Value |
|---|---|
| Dual PNP RET architecture | Two fully independent PNP transistors with matched on-chip R1/R2 bias networks reduce layout area by >40% vs discrete resistor+transistor solutions. |
| −100 mA per channel | Supports direct drive of optocoupler inputs, LED indicators, and low-power solenoid drivers without external amplification stages. |
| Integrated 47 kΩ bias resistors | Eliminates 4 external resistors per device, cutting pick-and-place steps and reducing risk of solder joint defects in automated assembly. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing-enables use in body electronics and ADAS subsystems. |
Applications
| Automotive Body Control Module | Industrial PLC Input Conditioning |

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 |
|---|---|---|---|
| PUMD12 | NPN/PNP complement; single NPN + single PNP pair; different pinout (I1/O1/GND1/I2/O2/GND2 vs PUMB2F's GND1/I1/O2/GND2/I2/O1). | Used where mixed-signal level translation (e.g., 5 V → 3.3 V pull-up + 3.3 V → 5 V pull-down) is required. | Select when circuit requires asymmetrical transistor polarity per channel rather than dual-PNP sinking. |
| PUMH2 | NPN/NPN configuration; identical SOT363-3 package and 47 kΩ R1/R2 values but opposite polarity and VCEO = +50 V. | Suitable for high-side switching or sourcing applications where load connects to ground and supply feeds collector. | Choose for sourcing-based logic interfaces (e.g., driving NMOS gate pulls) instead of sinking-based loads. |
Compared with PUMD12 and PUMH2, the PUMB2F uniquely delivers matched dual-PNP sinking capability with unified ground referencing-critical for noise-immune, low-side switched sensor interfaces in automotive domains where common-emitter stability and negative rail compatibility are mandatory.

FAQ
What is the maximum allowable continuous current per channel of the PUMB2F?
The PUMB2F supports −100 mA continuous output current per transistor under conditions defined in the datasheet: Tamb ≤ 25 °C, FR4 PCB with standard footprint. Derating applies above 25 °C-per-transistor power dissipation drops linearly to 0 mW at 150 °C ambient, governed by Rth(j-a) = 625 K/W.
Can the PUMB2F be used in high-frequency switching applications?
The PUMB2F has a typical transition frequency fT of 180 MHz at −5 V VCE, −10 mA IC, making it suitable for digital switching up to ~10 MHz. However, its primary design intent is DC and low-frequency (<1 MHz) interface buffering-not RF or high-speed PWM-due to inherent RET parasitic capacitance (Cc = 3 pF max).
How does the built-in R1/R2 network affect input drive requirements?
With R1 = 47 kΩ, the PUMB2F draws ~70 µA base current at 3.3 V input (VI(on) ≈ −1.6 V), enabling direct drive from most MCU GPIOs without additional current limiting. The R2 feedback resistor stabilizes bias point, improving thermal stability and reducing sensitivity to hFE variation across temperature.
Is the PUMB2F pin-compatible with other SOT363-3 RET devices like PUMH2?
No-PUMB2F uses a unique pinout (GND1/I1/O2/GND2/I2/O1), whereas PUMH2 uses GND1/I1/O1/GND2/I2/O2. Swapping them without PCB revision causes functional failure: O1 and O2 are swapped, reversing channel assignments and potentially shorting outputs. Always verify pin mapping against schematic symbols.
