Product details
Overview
PUMB3H-QX from Nexperia is a PNP/PNP resistor-equipped double transistor (RET) in SOT363 (SC-88) package, rated for −50 V VCEO, −100 mA output current per transistor, with built-in 4.7 kΩ base bias resistor (R1) and open R2 configuration. It serves as a dual high-temperature switching element for digital logic interfacing and load control in automotive-grade circuits.
For engineers reviewing the PUMB3H-QX datasheet, PUMB3H-QX pinout, PUMB3H-QX application, or PUMB3H-QX equivalent, this device offers AEC-Q101 qualification, simplified BOM reduction via integrated resistors, and validated operation up to 175 °C ambient - critical for under-hood automotive modules, industrial I/O buffers, and space-constrained digital power sequencing.
Technical Context
This dual PNP RET integrates two matched PNP transistors with independent emitter-grounded configurations and dedicated base inputs. Each transistor features a factory-trimmed 4.7 kΩ (typ.) input resistor (R1), while R2 is unconnected - enabling direct TTL/CMOS-compatible switching without external bias networks.
It operates within −55 °C to +175 °C ambient range, supports 240 mW per transistor and 360 mW per device power dissipation on FR4 PCB, and delivers hFE ≥ 200 at −1 mA IC, with VCE(sat) ≤ −100 mV at −10 mA IC/−0.5 mA IB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter voltage per transistor; 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 (typ.) - Integrated base bias resistor; eliminates need for external pull-up/pull-down, reducing footprint and assembly cost. |
| Tj(max) | 175 °C - Maximum junction temperature; supports AEC-Q101-compliant under-hood deployment without derating. |
| hFE | ≥200 @ −1 mA IC, −5 V VCE - High DC current gain ensures reliable saturation with low base drive current. |
| VCE(sat) | ≤ −100 mV @ −10 mA IC, −0.5 mA IB - Low saturation voltage minimizes conduction loss in switching applications. |
| fT | 180 MHz (typ.) - Transition frequency of internal transistors; supports fast digital switching up to ~10–20 MHz edge rates. |
Pinout & Package
SOT363 (SC-88/TSSOP6) plastic surface-mount package: 6-pin, 0.65 mm pitch, 2.1 mm × 1.25 mm × 0.95 mm body; optimized for reflow soldering on FR4 PCBs with standard footprint per Figure 12.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1; common reference node for first transistor's current path. |
| 2 | I1 | Base input for TR1; accepts logic-level signals (VI(on) ≤ −0.88 V) to activate TR1. |
| 3 | O2 | Collector output for TR2; sinks current when TR2 is active; electrically isolated from O1. |
| 4 | GND2 | Emiter connection for TR2; independent ground node enabling dual-channel isolation. |
| 5 | I2 | Base input for TR2; independently controllable input for second switching channel. |
| 6 | O1 | Collector output for TR1; provides first switched output; shares no internal connection with O2. |
Key Features
| Feature | Design Value |
|---|---|
| Dual PNP RET architecture | Two independent PNP transistors with shared package but isolated emitters (GND1/GND2) and collectors (O1/O2), enabling separate load control paths. |
| Integrated R1 bias network | Factory-trimmed 4.7 kΩ resistor per base input (I1/I2); eliminates discrete bias components and reduces layout complexity. |
| AEC-Q101 qualification | Stress-tested per Automotive Electronics Council standard; qualified for permanent installation in engine control units, body electronics, and ADAS sensors. |
| High-temperature operation | Rated for continuous operation from −55 °C to +175 °C ambient; thermal resistance Rth(j-a) = 417 K/W (per device) ensures stable performance in sealed enclosures. |
| Low VI(off) threshold | Off-state input voltage ≤ −500 mV; guarantees robust noise immunity against EMI in automotive harness environments. |
Applications
| Automotive Body Control Module (BCM) | Industrial Digital I/O Buffer |
|---|---|

IC Role / Device Role / Timing Role: Dual transistor used for motor gate drive enable and tachometer signal inversion. Use Value: Withstands 150 °C under-hood thermal cycling; VCE(sat) remains ≤ −120 mV after 1000 hrs HTOL stress. |
Use Scenario: Coordinating power-up sequence of MCU, display backlight, and sensor subsystems in smart home hubs. IC Role / Device Role / Timing Role: Dual independent switch managing reset line assertion and backlight enable timing. Use Value: Matches BC857B pinout compatibility while integrating bias resistors - drop-in replacement with zero layout change. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual PNP switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC857BDW1T1G | Discrete dual PNP pair (no built-in resistors); requires external 4.7 kΩ base resistors per channel. | Higher BOM count and PCB area; lacks AEC-Q101 qualification; max Tamb = 150 °C. | Select when legacy design reuse or fine-tuned bias adjustment is required; not recommended for new automotive designs. |
| PUMD6H-Q | NPN/PNP RET variant; includes R1 = 10 kΩ and R2 = 10 kΩ; different polarity pairing and resistor values. | Used where mixed-signal level translation (e.g., NPN input → PNP output) is needed; incompatible pinout (different GND/emitter assignment). | Choose only for NPN/PNP functional requirements; not a drop-in substitute due to polarity mismatch and pin mapping divergence. |
Compared with BC857BDW1T1G, PUMB3H-QX reduces bill-of-materials by four passive components and extends temperature rating by 25 °C; versus PUMD6H-Q, it provides matched PNP/PNP topology with lower R1 value for faster turn-on in 3.3 V logic systems.

FAQ
Is PUMB3H-QX pin-compatible with BC857 series transistors?
No - PUMB3H-QX uses a 6-pin SOT363 package with dual isolated emitters (pins 1 and 4), whereas BC857 variants are 3-pin SOT23 devices. While functionally similar as PNP switches, the pinout, package size, and integrated resistor topology differ fundamentally; board redesign is required for substitution.
What is the maximum allowable input voltage at I1 and I2 pins?
The absolute maximum input voltage at I1 and I2 is −30 V to +7 V per datasheet Table 5. This range accommodates transient spikes in automotive 12 V systems and ensures safe operation during load dump events when used with appropriate clamping diodes on upstream logic lines.
Does PUMB3H-QX support parallel operation of both transistors for higher current?
No - TR1 and TR2 share no internal current-sharing mechanism; their collectors (O1/O2) and emitters (GND1/GND2) are fully isolated. Parallel connection would cause unequal current distribution due to hFE mismatch and thermal coupling, risking premature failure of one transistor. Use per-channel loads only.
Can PUMB3H-QX be used in linear amplifier configurations?
No - it is optimized and characterized exclusively for switching operation. The datasheet specifies no linear-region parameters (e.g., output conductance, distortion metrics), and its built-in resistors prevent stable DC biasing for analog amplification; use dedicated general-purpose PNP transistors like BC857 for such applications.
