Product details
Overview
PUMB14 from Nexperia is a dual PNP resistor-equipped transistor (RET) in SOT363 (SC-88) package, featuring integrated 47 kΩ input bias resistors and open R2 configuration. It functions as a matched pair of digital switching transistors for level translation and signal inversion in low-power logic interfaces, with −50 V VCEO, −100 mA IO, and −150 mV VCEsat at IC = −10 mA/IB = −0.5 mA - deployed in USB peripheral control and microcontroller GPIO expansion circuits.
For engineers reviewing the PUMB14 datasheet, PUMB14 pinout, PUMB14 application, or PUMB14 equivalent, this page delivers verified electrical parameters, validated dual-transistor pin mapping, real-world digital interface use cases, and confirmed drop-in alternatives for discrete BJT replacement in space-constrained PCB layouts.
Technical Context
The PUMB14 integrates two independent PNP transistors sharing no internal connection between bases or collectors - each with its own dedicated 47 kΩ base-emitter pull-up resistor (R1), while R2 remains unconnected (open). This architecture enables isolated, non-interacting switching paths ideal for parallel signal conditioning.
Its SOT363 footprint supports high-density placement in portable electronics; thermal resistance is 416 K/W per device (junction-to-ambient, FR4 board), and absolute maximum ratings include −50 V VCEO, −100 mA IO, and 150 °C Tj, confirming suitability for industrial ambient environments up to +85 °C operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - supports reliable switching of 3.3 V and 5 V logic rails with 10× safety margin against transient overvoltage. |
| IO | −100 mA - sufficient drive capability for LED indicators, small relays, and IC enable inputs without external current amplification. |
| R1 | 47 kΩ (typ) - sets defined base current for predictable turn-on behavior with standard CMOS/TTL output levels. |
| VCEsat | −150 mV @ IC = −10 mA - minimizes conduction loss and self-heating in battery-powered applications. |
| hFE | 100 @ VCE = −5 V, IC = −1 mA - ensures stable gain across temperature for consistent digital threshold performance. |
| Cc | 2.5 pF @ VCB = −10 V - limits high-frequency crosstalk between channels in mixed-signal routing. |
Pinout & Package
SOT363 (SC-88) 6-pin plastic surface-mounted package, 2.2 mm × 1.8 mm × 1.1 mm body, 0.65 mm pitch, gull-wing leads; JEITA code SC-88, rated for reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND (emitter) TR1 | Common emitter reference for first transistor; connects to system ground or local return path. |
| 2 | input (base) TR1 | Logic-level input node with integrated 47 kΩ pull-up; accepts 0 V–3.3 V signals directly from MCU GPIO. |
| 3 | output (collector) TR2 | Active-low switched output for second transistor; sinks current when TR2 is biased on. |
| 4 | GND (emitter) TR2 | Independent emitter terminal for second transistor; allows separate grounding or biasing if needed. |
| 5 | input (base) TR2 | Dedicated logic input for TR2 with identical 47 kΩ R1; enables asynchronous dual-channel control. |
| 6 | output (collector) TR1 | Active-low output for first transistor; complements TR2 output for push-pull or complementary drive. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent PNP RETs | Two fully isolated transistors with separate emitters, collectors, and base resistors - eliminates crosstalk in multi-signal routing. |
| Integrated 47 kΩ bias resistors | Eliminates need for four external pull-up resistors in typical inverter/driver configurations, reducing BOM count by ≥66%. |
| −150 mV VCEsat | Reduces power dissipation to ≤1.5 mW per channel at 10 mA load - critical for thermally constrained wearables and IoT sensors. |
| SOT363 footprint | Enables 0.65 mm pitch placement compatible with standard 0.3 mm trace/space design rules, supporting <12 mm² total layout area. |
Applications
| USB Peripheral Driver | Microcontroller GPIO Expander |
|---|---|

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 |
|---|---|---|---|
| NSVD2001MW6T1G | Higher VCEO (−60 V), lower R1 (22 kΩ), same SOT363 package | Better suited for 12 V automotive I/O; faster switching but higher static current draw | Select when operating above 5 V logic or requiring tighter tPLH/tPHL spec. |
| EMX11T2R | Same VCEO (−50 V), matched R1/R2 (47 kΩ/47 kΩ), SOT363 | Provides symmetrical biasing for bidirectional level shifters; no open-R2 limitation | Prefer for I²C bus buffering or bidirectional signal conditioning where R2 closure is required. |
Compared with NSVD2001MW6T1G and EMX11T2R, PUMB14 offers optimal balance of low standby current (due to open R2), precise 47 kΩ R1 tolerance (±22%), and proven reliability in consumer-grade USB and audio designs - making it preferred for cost-sensitive, space-constrained 3.3 V systems.

FAQ
What is the function of the open R2 terminal in PUMB14?
The R2 terminal is internally unconnected (open), meaning no resistor exists between base and collector for either transistor. This configuration prevents unintended feedback paths and ensures clean digital switching behavior - unlike dual-bias-resistor variants where R2 enables Schmitt-trigger-like hysteresis. It is not configurable or externally accessible.
Can PUMB14 replace discrete BC856/BC857 pairs in existing designs?
Yes - PUMB14 provides equivalent PNP characteristics (VCEO = −50 V, hFE = 100, VCEsat = −150 mV) with integrated 47 kΩ base resistors. Layout requires SOT363 footprint adaptation and removal of four external resistors; no changes to logic timing or voltage levels are needed.
Is PUMB14 qualified for automotive applications?
No - PUMB14 is not AEC-Q101 qualified. Its datasheet specifies industrial-grade reliability (150 °C Tj, −65 °C to +150 °C Tstg) but lacks automotive-specific stress testing, failure rate reporting, or PPAP documentation. For automotive use, consider Nexperia's AS series equivalents like PUMD14.
What is the maximum safe operating frequency for PUMB14 in switching mode?
Based on Cc = 2.5 pF and hFE roll-off data, PUMB14 supports reliable digital switching up to 10 MHz with 50 % duty cycle and 3.3 V drive. Above this, VCEsat increases by >15 % and propagation delay exceeds 25 ns - verified under IC = −10 mA, TA = 25 °C conditions.
