Product details
Overview
PUMB15 from Nexperia is a dual PNP resistor-equipped transistor (RET) in SOT363 (SC-88) package, configured as two independent PNP transistors with integrated 4.7 kΩ input bias resistors (R1) and matched R2/R1 ratio of 1.0. It delivers −100 mA output current per transistor, supports −50 V collector-emitter voltage, and is AEC-Q101 qualified for automotive signal conditioning and digital logic interface applications.
For engineers reviewing the PUMB15 datasheet, PUMB15 pinout, PUMB15 application, or PUMB15 equivalent, this device serves as a space- and BOM-optimized replacement for discrete PNP pairs in level-shifting, LED driver enable control, and microcontroller I/O buffering where built-in biasing eliminates external resistors and reduces placement cost.
Technical Context
The PUMB15 integrates two identical PNP bipolar transistors with monolithically embedded base bias networks-each featuring R1 = 4.7 kΩ (input resistor) and R2 = 4.7 kΩ (base-emitter feedback resistor), yielding a precise R2/R1 ratio of 1.0 (±20%). Its dual-transistor topology enables independent switching control on six terminals with shared ground connections at pins 1 and 4.
Designed for digital switching, it operates with VI(on) = −1.9 V (typ.) at IC = −20 mA and VI(off) = −1.1 V (typ.) at IC = −100 µA, ensuring robust noise margin in 3.3 V/5 V logic environments. Thermal resistance is 417 K/W per device on FR4 PCB, supporting continuous operation up to +150 °C junction temperature.
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 DC output current per transistor; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 4.7 kΩ (3.3–6.1 kΩ) - Integrated input bias resistor; eliminates need for external pull-up/pull-down in gate/base drive circuits. |
| R2/R1 ratio | 1.0 (0.8–1.2) - Ensures consistent turn-on threshold and predictable hFE dependency across process variation. |
| Ptot (per device) | 300 mW at Tamb ≤ 25 °C - Total dissipation limit for both transistors; defines maximum combined switching load under ambient conditions. |
| hFE | ≥30 at VCE = −5 V, IC = −10 mA - Minimum DC current gain; guarantees reliable saturation with standard microcontroller GPIO drive. |
| fT | 180 MHz - Transition frequency; supports clean switching up to ~10–20 MHz digital signals without excessive delay. |
Pinout & Package
SOT363 (SC-88) surface-mount plastic package: 1.3 mm × 2.2 mm footprint, 0.65 mm pitch, 6-terminal ultra-small outline with pin 1 index marker. Moisture sensitivity level (MSL) 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND (emitter of TR1) | Common emitter reference for first transistor; connects to system ground or low-side return path. |
| 2 | Input (base of TR1) | Resistor-biased base node of TR1; accepts logic-level input directly without external RB. |
| 3 | Output (collector of TR2) | Active-low switched output of second transistor; sinks current when TR2 is on. |
| 4 | GND (emitter of TR2) | Common emitter reference for second transistor; electrically isolated from pin 1 but functionally identical. |
| 5 | Input (base of TR2) | Resistor-biased base node of TR2; independently controllable from pin 2. |
| 6 | Output (collector of TR1) | Active-low switched output of first transistor; complements pin 3 for dual-channel control. |
Key Features
| Feature | Design Value |
|---|---|
| Dual PNP RET topology | Two fully independent, resistor-equipped PNP transistors in one SC-88 package-reduces board area by >40% vs. discrete pair. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM ≥2 kV)-enables use in body control modules and infotainment I/O. |
| Matched R1/R2 network | 4.7 kΩ ±28% R1 with 1.0 ±20% R2/R1 ratio ensures consistent turn-on behavior across both channels and lot-to-lot stability. |
| Low VI(on) / VI(off) | VI(on) = −1.9 V (typ.), VI(off) = −1.1 V (typ.) - Enables direct interfacing with 3.3 V CMOS outputs without level translation. |
| High fT and low Cc | fT = 180 MHz and Cc = 3 pF - Supports fast edge rates and minimizes capacitive loading on driving logic. |
Applications
| Automotive Door Module | Industrial PLC Input Card |
|---|---|
|
Use Scenario: Level-shifting and isolation of door lock/unlock switch signals from 12 V vehicle bus to 3.3 V MCU GPIO. IC Role / Device Role: Dual-channel active-low signal conditioner-TR1 processes lock command, TR2 handles unlock command. Use Value: Eliminates four external bias resistors and two discrete transistors; reduces component count by 67% and improves layout density. |
Use Scenario: Converting 24 V dry-contact inputs from field sensors into clean 5 V logic levels for FPGA-based input acquisition. IC Role / Device Role: Dual-channel high-side switch interface-each PNP RET acts as an open-collector inverter with internal pull-up. Use Value: Enables direct connection to mechanical contacts without external pull-ups; supports >100 kHz polling rate due to 180 MHz fT. |
| Consumer Appliance Control Board | Medical Diagnostic Instrument I/O |
|
Use Scenario: Driving bi-color LED status indicators from low-power ARM Cortex-M0+ GPIOs with minimal external components. IC Role / Device Role: Dual-sink driver-TR1 controls red segment, TR2 controls green segment via common-anode configuration. Use Value: Delivers −100 mA per channel to drive high-brightness LEDs at full intensity; thermal derating allows sustained operation at 60 °C ambient. |
Use Scenario: Isolating patient-connected sensor enable lines from main controller to meet IEC 62304 leakage current limits. IC Role / Device Role: Low-leakage digital switch-ICEO ≤ −1 µA at 25 °C and ≤ −5 µA at 150 °C ensures <100 nA system-level leakage. Use Value: Meets stringent medical safety requirements without additional guarding circuitry; validated per AEC-Q101 stress protocols. |
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 |
|---|---|---|---|
| NSVD2P0330MUTBG | Single PNP RET in SOT-563; only one channel, no dual configuration. | Requires two devices for dual-channel function; increases board area and assembly cost. | Select only if single-channel operation suffices and footprint flexibility is prioritized over integration. |
| EMX11T2R | PNP/NPN complementary RET pair in SOT-363; includes one PNP + one NPN transistor. | Enables push-pull output stages but lacks dual-PNP symmetry required for active-low parallel control. | Choose when complementary drive (e.g., half-bridge gate control) is needed-not for dual identical PNP switching. |
Compared with NSVD2P0330MUTBG and EMX11T2R, PUMB15 uniquely provides two matched PNP RETs in one SC-88 package-delivering optimal BOM reduction and signal consistency for applications requiring identical active-low switching paths without polarity inversion.

FAQ
Is PUMB15 pin-compatible with PEMB15?
No. PUMB15 uses SOT363 (SC-88) package with 0.65 mm lead pitch and 6-pin arrangement (1–6: GND/TR1, IN/TR1, OUT/TR2, GND/TR2, IN/TR2, OUT/TR1). PEMB15 uses SOT666 with 0.5 mm pitch and different pin mapping. Footprint and solder reflow profiles are not interchangeable.
What is the maximum allowable continuous current per channel?
The absolute maximum continuous output current per transistor is −100 mA, as specified in Table 6 (Limiting Values). At this current and 25 °C ambient, power dissipation reaches 150 mW per transistor (assuming VCE(sat) ≈ −150 mV), staying within the 300 mW per-device total limit.
Can PUMB15 be used in 1.8 V logic systems?
Not reliably. VI(on) is −1.9 V (typ.) at −20 mA, meaning a 1.8 V logic high cannot forward-bias the base-emitter junction sufficiently. Minimum recommended supply is 3.3 V; for 1.8 V systems, a level shifter or alternative low-VBE device is required.
Does PUMB15 require external decoupling capacitors?
No dedicated decoupling is required. The device contains no internal regulators or oscillators. However, a 100 nF ceramic capacitor between each GND pin (1 and 4) and local power rail is recommended to suppress switching transients when driving inductive loads like relays or solenoids.
