Product details
Overview
PUMB24 from Nexperia is a dual PNP resistor-equipped transistor (RET) in SOT363 (SC-88) package, featuring integrated 100 kΩ input bias resistors (R1 = R2 = 100 kΩ) per transistor, −50 V VCEO, −20 mA IO, and AEC-Q101 qualification for automotive use in low-current digital switching applications such as IC input control and peripheral driver circuits.
For engineers reviewing the PUMB24 datasheet, PUMB24 pinout, PUMB24 application, or PUMB24 equivalent, this device supports simplified digital logic interfacing with built-in biasing, reduced BOM count, and validated thermal performance on FR4 PCBs - critical for space-constrained automotive and industrial control designs.
Technical Context
The PUMB24 integrates two matched PNP transistors with monolithically embedded base bias resistors (R1 and R2), eliminating external pull-up/pull-down components. Each channel operates with open-base VCEO = −50 V and output current capability up to −20 mA under DC conditions.
Its dual-channel configuration enables independent control of two digital loads with identical biasing topology (R1 = R2 = 100 kΩ, R2/R1 ratio = 1.0 typ), supporting direct interface to microcontroller GPIOs or logic gates without discrete resistor networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum collector-emitter voltage before breakdown; defines safe operating range for 24 V automotive supply interfaces. |
| IO | −20 mA: Continuous DC output current per transistor; sufficient for driving LED indicators or small-signal logic inputs. |
| R1 | 100 kΩ (typ): Integrated base input resistor; sets input current threshold for turn-on at ~−5 µA with −0.7 V VBE. |
| R2/R1 | 1.0 (typ): Unity bias resistor ratio; ensures symmetric saturation behavior and predictable VI(on)/VI(off) thresholds. |
| Ptot (per device) | 300 mW @ Tamb ≤ 25 °C: Total power dissipation limit on standard FR4 PCB; supports stable operation without heatsinking in low-duty-cycle apps. |
| hFE | 80 (min @ IC = −5 mA, VCE = −5 V): Minimum DC current gain; guarantees reliable saturation with modest base drive. |
| VCE(sat) | −150 mV (max @ IC = −5 mA, IB = −0.25 mA): Low saturation voltage; minimizes power loss and voltage drop in active-switching mode. |
Pinout & Package
SOT363 (TSSOP6) plastic surface-mount package: 6-pin, 0.65 mm pitch, 2.1 mm × 1.25 mm × 0.95 mm body; designed for reflow soldering on FR4 PCBs with standard footprint per Figure 9.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1; common reference node for first transistor channel. |
| 2 | I1 | Base input for TR1; internally connected to R1 (100 kΩ) to GND1. |
| 3 | O2 | Collector output for TR2; active-low switching node for second channel. |
| 4 | GND2 | Emiter connection for TR2; isolated reference node for second transistor channel. |
| 5 | I2 | Base input for TR2; internally connected to R1 (100 kΩ) to GND2. |
| 6 | O1 | Collector output for TR1; active-low switching node for first channel. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors (R1 = R2 = 100 kΩ) | Eliminates need for 4 external resistors in dual-transistor logic buffer design, reducing layout area by >30%. |
| AEC-Q101 qualified | Validated for automotive temperature range (−40 °C to +150 °C) and reliability stress tests, enabling use in body electronics modules. |
| Low VCE(sat) (−150 mV max) | Reduces conduction loss in always-on or pulsed switching modes, improving efficiency in battery-powered sensor interfaces. |
| SOT363 package footprint | Enables high-density placement in space-limited applications like infotainment button arrays or ADAS camera module PCBs. |
| Matched dual PNP topology | Ensures consistent timing and drive strength across both channels, simplifying timing-critical enable/disable sequencing. |
Applications
| Automotive Door Module Driver | Industrial PLC Input Buffer |
|---|---|
Use Scenario: Driving LED status indicators and small solenoid enable lines in vehicle door control units.

IC Role / Device Role / Timing Role: Safe, current-limited interface protecting MCU pins from ESD and overvoltage events on patient-connected peripherals. Use Value: Integrated bias network eliminates floating base conditions, preventing unintended turn-on during system reset or brown-out events. |
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 |
|---|---|---|---|
| PUMH24 | NPN/NPN complement; same package and bias values but opposite polarity; requires inverted logic drive. | Used where active-high switching or sourcing (vs sinking) is required, e.g., driving N-channel MOSFET gates. | Select when interfacing with open-collector outputs or needing source-mode current delivery. |
| PUMD24 | NPN/PNP configuration; asymmetric channel types; shares same R1/R2 values but different transistor pairing. | Suitable for level translation between mixed-polarity logic domains, e.g., 3.3 V MCU to 5 V peripheral buses. | Choose when one channel must sink and the other source current simultaneously in bidirectional signal paths. |
Compared with PUMH24 and PUMD24, the PUMB24 provides matched dual-sink capability ideal for redundant or parallel load control, while its PNP-only structure avoids cross-conduction risks in synchronous switching topologies.

FAQ
What is the maximum ambient temperature for continuous operation of PUMB24?
The PUMB24 supports continuous operation from −65 °C to +150 °C ambient temperature, with junction temperature limited to 150 °C. Derating begins above 25 °C ambient per the 416 K/W per-device thermal resistance curve in Figure 1, requiring power reduction to maintain safe Tj.
Can PUMB24 be used in 5 V logic systems?
Yes - PUMB24's VI(on) ranges from −3 V to −1.6 V (typ) and VI(off) from −1.2 V to −0.5 V, making it compatible with 5 V TTL and CMOS logic families when driven through appropriate level-shifting or pull-up configurations; no additional biasing is needed due to integrated R1/R2.
Is the SOT363 package lead-free and RoHS compliant?
Yes - the PUMB24 in SOT363 package uses lead-free terminations and complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, as confirmed in Nexperia's official compliance documentation and material declarations.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 0.8–1.2 (typ 1.0) directly determines the internal feedback path that stabilizes base voltage during saturation. A ratio near unity ensures balanced VI(on)/VI(off) hysteresis and prevents latch-up in noisy environments, unlike asymmetric ratios which may cause inconsistent turn-off thresholds.
