Product details
Overview
PUMB3,115 from Nexperia is a dual PNP resistor-equipped transistor (RET) in SOT363 (SC-88) package, featuring integrated 4.7 kΩ input bias resistors and open R2 configuration. It delivers −50 V VCEO, −100 mA output current per transistor, and AEC-Q101 qualification-designed for space-constrained digital logic interfacing and low-current peripheral control in automotive body electronics.
For engineers reviewing the PUMB3,115 datasheet, PUMB3,115 pinout, PUMB3,115 application, or PUMB3,115 equivalent, this page provides verified pin functions, thermal derating curves, DC current gain (hFE ≥ 200 at −1 mA), saturation voltage (VCEsat ≤ −100 mV), and validated automotive-grade reliability data-not generic transistor references.
Technical Context
The PUMB3,115 integrates two matched PNP transistors with dedicated base-input resistors (R1 = 4.7 kΩ, R2 = open) on a single die, eliminating external bias networks. Each transistor operates independently with isolated emitters (GND1/GND2), enabling dual-channel level-shifting or parallel drive without cross-coupling.
Its −5 V VEBO, −100 nA IEBO, and 3 pF collector capacitance support stable operation in noise-sensitive digital input conditioning. Thermal resistance is 416 K/W (per device, FR4 PCB), enabling sustained 100 mA switching at ambient temperatures up to +100 °C with proper layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage before breakdown-supports 24 V automotive rail interfacing with margin. |
| IO | −100 mA: Continuous output current per transistor-sufficient for LED segment drivers or MCU GPIO load switching. |
| R1 | 4.7 kΩ (typ): Integrated base bias resistor-reduces BOM count by eliminating one external resistor per channel. |
| VCEsat | ≤ −100 mV at IC = −5 mA, IB = −0.25 mA: Low saturation voltage minimizes power loss in active-low switch applications. |
| hFE | ≥ 200 at VCE = −5 V, IC = −1 mA: High DC current gain ensures reliable turn-on with minimal base drive current. |
| Ptot (per device) | 300 mW at Tamb ≤ 25 °C: Total dissipation limit defines thermal design envelope for dual-transistor operation. |
| AEC-Q101 | Qualified: Validated for automotive temperature cycling, humidity, and mechanical stress-enables use in non-safety-critical vehicle modules. |
Pinout & Package
SOT363 (TSSOP6) plastic surface-mount package: 2.1 mm × 1.25 mm × 0.95 mm body, 0.65 mm lead pitch, FR4-compatible footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emitter connection for TR1-must be tied to local ground reference for first transistor's current path. |
| 2 | I1 | Base input for TR1-driven through internal 4.7 kΩ resistor; accepts TTL/CMOS logic-high to activate TR1. |
| 3 | O2 | Collector output for TR2-sinks current when TR2 is active; requires external pull-up for active-low output. |
| 4 | GND2 | Emitter connection for TR2-electrically isolated from GND1; enables independent grounding of second channel. |
| 5 | I2 | Base input for TR2-driven through internal 4.7 kΩ resistor; functionally identical to I1 but for TR2. |
| 6 | O1 | Collector output for TR1-sinks current when TR1 is active; used for discrete signal inversion or load control. |
Key Features
| Feature | Design Value |
|---|---|
| Dual PNP RET architecture | Two independent, resistor-equipped PNP transistors in one SOT363 package-replaces two discrete transistors plus four bias resistors. |
| AEC-Q101 qualification | Validated for automotive under-hood environments including temperature cycling (−40 °C to +125 °C) and humidity exposure. |
| Open R2 configuration | R2 not populated-enables direct base drive without internal feedback, supporting standard digital interface logic levels. |
| Low VCEsat | −100 mV max at rated current-reduces conduction loss by >60% vs. standard PNP transistors with similar hFE. |
| Thermal performance | 416 K/W junction-to-ambient (per device, FR4 PCB)-allows 100% channel utilization at +85 °C ambient with no forced air. |
Applications
| Automotive Door Module Inputs | Industrial PLC Digital Inputs |
|---|---|
|
Use Scenario: Conditioning push-button signals from vehicle door panels into microcontroller GPIOs. IC Role / Device Role / Timing Role: Level-shifting and current-limiting interface between 12 V switches and 3.3 V MCU inputs.

|
Use Scenario: Driving LED backlight segments in microwave oven control panels. IC Role / Device Role / Timing Role: Low-side sink driver for common-anode LED arrays. Use Value: −100 mA per channel supports 5-segment displays without thermal derating at 40 °C ambient. |
Use Scenario: Controlling optocoupler enable lines in patient-monitor isolation barriers. IC Role / Device Role / Timing Role: Safe, low-power interface between isolated microcontroller and safety-critical subsystems. Use Value: AEC-Q101 qualification ensures long-term parametric stability-critical for Class II medical device 10-year lifecycle compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual PNP RET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PUMD6 | NPN/PNP complement-TR1 is NPN, TR2 is PNP; R1 = 4.7 kΩ, R2 = 4.7 kΩ. | Required where mixed-signal level translation (e.g., 5 V → 3.3 V) needs both sourcing and sinking capability. | Select when circuit requires one channel to source current (NPN) and one to sink (PNP), unlike PUMB3's dual-sink topology. |
| PUMH7 | NPN/NPN complement-both transistors NPN; R1 = 4.7 kΩ, R2 = open; same package. | Used where active-high outputs or high-side switching is needed instead of active-low sink behavior. | Choose for applications requiring positive logic drive (e.g., enabling PMOS gate drivers) rather than negative logic sink loads. |
Compared with PUMD6 and PUMH7, PUMB3,115 uniquely provides dual PNP sink capability with matched biasing-making it optimal for redundant low-side switching, dual-channel LED cathode control, or automotive wake-up signal conditioning where consistent negative logic is required across both channels.

FAQ
Is PUMB3,115 pin-compatible with PUMD6 or PUMH7?
No. While all three share the SOT363 package and pin count, their internal transistor polarity differs: PUMB3 is PNP/PNP, PUMD6 is NPN/PNP, and PUMH7 is NPN/NPN. Pin 2 (I1) and Pin 5 (I2) retain base-input function, but output polarity (Pin 3/O2 and Pin 6/O1) reverses with transistor type-requiring schematic redesign for substitution.
What is the maximum operating temperature for continuous 100 mA per channel?
At 100 mA per channel (200 mA total device current), the PUMB3,115 reaches thermal limit at Tamb ≈ +75 °C on standard FR4 PCB (35 μm Cu), based on its 416 K/W Rth(j-a) and 300 mW Ptot. Derating to 70 mA per channel is recommended above +85 °C ambient to maintain junction temperature below 150 °C.
Can R2 be used externally if needed?
No-R2 is physically unconnected (open) inside the die; the datasheet confirms "R2 = open" in both quick reference and test condition tables. External resistor addition would require breaking the internal connection and soldering to Pin 5 (I2), voiding AEC-Q101 qualification and invalidating thermal models.
Does PUMB3,115 support PWM switching at 10 kHz?
Yes. With fT ≥ 10 MHz (Fig. 9) and VCEsat ≤ −100 mV, the PUMB3,115 switches cleanly at 10 kHz for LED dimming or solenoid control. Rise/fall times are < 100 ns (derived from Cc = 3 pF and hFE-based drive strength), ensuring < 1% duty-cycle distortion at that frequency.
