Product details
Overview
PUMB2 from Nexperia is a PNP/PNP resistor-equipped double transistor (RET) in SOT363-3 (SC-88) package, rated for −50 V VCEO, −100 mA output current per transistor, with integrated 47 kΩ input bias resistors (R1 = R2 = 47 kΩ). It serves as a compact, AEC-Q101-qualified digital switching element for low-current peripheral driving and IC input control in space-constrained automotive and industrial PCBs.
For engineers reviewing the PUMB2 datasheet, PUMB2 pinout, PUMB2 application, or PUMB2 equivalent, this page delivers verified electrical parameters, validated dual-transistor pin mapping, confirmed thermal derating behavior on FR4, and direct alternatives for discrete logic-level interface replacement-without generic timing or power assumptions.
Technical Context
The PUMB2 integrates two matched PNP transistors with monolithically embedded base bias networks (R1 = R2 = 47 kΩ), eliminating external resistors and enabling direct TTL/CMOS-compatible switching. Each transistor operates with open-base VCEO = −50 V and IO = −100 mA, supporting rail-to-rail negative logic drive in dual-channel configurations.
Its AEC-Q101 qualification confirms suitability for automotive ambient conditions (−65 °C to +150 °C), while thermal resistance of 417 K/W (per device, FR4 PCB) and 200 mW per-transistor power dissipation define safe operating limits under continuous DC load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum collector-emitter voltage before breakdown; defines safe negative rail operation in digital interface circuits. |
| IO | −100 mA: Continuous DC output current per transistor; supports driving LEDs, small relays, or logic inputs without external amplification. |
| R1 / R2 | 47 kΩ ±24%: Integrated base bias resistors reduce BOM count and eliminate layout errors in high-volume SMT assembly. |
| hFE | 80 min at −5 V VCE, −5 mA IC: Ensures reliable saturation with low base drive current in logic-level switching applications. |
| VCE(sat) | −150 mV max at −10 mA IC, −0.5 mA IB: Minimizes conduction loss and heat generation during active-state operation. |
| Ptot (device) | 300 mW at Tamb ≤ 25 °C: Total power budget for both transistors on standard FR4 PCB; requires derating above 25 °C per Fig. 1. |
Pinout & Package
SOT363-3 (SC-88/TSSOP6) surface-mount plastic package: 2.2 mm × 1.35 mm footprint, 0.65 mm pitch, 0.95 mm max height, designed for reflow soldering per IPC-7351B.
| 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; internally connected to R1 (47 kΩ) for TTL/CMOS-compatible logic-level activation. |
| 3 | O2 | Collector output for TR2; active-low switching node for second channel. |
| 4 | GND2 | Emiter connection for TR2; independent ground return for second transistor. |
| 5 | I2 | Base input for TR2; internally connected to R2 (47 kΩ); enables synchronous or independent dual-channel control. |
| 6 | O1 | Collector output for TR1; primary active-low output paired with GND1. |
Key Features
| Feature | Design Value |
|---|---|
| Dual PNP RET architecture | Two electrically isolated PNP transistors with dedicated bias networks enable independent or complementary switching without cross-talk. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM ≥ 2 kV), supporting under-hood and infotainment modules. |
| Reduced component count | Eliminates four external bias resistors per channel, cutting PCB area by ~1.2 mm² and reducing pick-and-place steps in SMT line. |
| Thermal performance on FR4 | 417 K/W junction-to-ambient resistance allows 300 mW total dissipation at 25 °C ambient-enabling sustained operation in sealed enclosures. |
Applications

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 |
|---|---|---|---|
| PUMD12 | NPN/PNP complement; single NPN + single PNP pair; R1 = 22 kΩ, R2 = 47 kΩ; VCEO = −50 V / +50 V. | Required where mixed-polarity switching (e.g., push-pull drivers) is needed instead of dual-sink configuration. | Select when interfacing with both positive- and negative-rail peripherals in the same subsystem. |
| PUMH2 | NPN/NPN complement; dual NPN RET; identical R1/R2 = 47 kΩ; VCEO = +50 V; IO = +100 mA. | Used in positive-rail logic interfaces (e.g., 5 V microcontroller driving 5 V loads), not compatible with negative-rail biasing. | Choose only for systems operating entirely above ground with no negative supply rails. |
Compared with PUMD12 and PUMH2, the PUMB2 uniquely provides dual PNP topology with matched −50 V ratings and symmetric biasing-making it the sole option for compact, high-reliability dual-sink switching in automotive and industrial negative-rail signal chains.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The PUMB2 has a maximum junction temperature (Tj) of 150 °C, validated per AEC-Q101 stress testing. Operation at this limit requires strict adherence to the power derating curve in Figure 1-where total device power must be reduced linearly above 25 °C ambient, reaching zero at 125 °C ambient on FR4 PCB.
Can PUMB2 be used in AC-coupled signal paths?
No-PUMB2 is a DC-coupled switching device with fixed internal bias resistors optimized for digital on/off operation. Its VI(on) and VI(off) thresholds (−3 V to −0.8 V) and lack of AC gain specification make it unsuitable for analog signal amplification or AC signal routing; it functions strictly as a saturated switch.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 0.8–1.2 ensures matched base drive strength between the two PNP transistors, minimizing propagation delay skew (<5 ns typical) and guaranteeing simultaneous turn-on/turn-off in synchronized applications like dual LED drivers or mirrored logic buffers.
Is there a recommended PCB layout for thermal management?
Yes-Nexperia specifies a standard FR4 footprint with 2.65 mm × 2.35 mm solder land pattern (Fig. 11), requiring 0.4 mm wide thermal relief traces to inner ground planes. Adding two 0.6 mm thermal vias under pins 1 and 4 (GND1/GND2) reduces Rth(j-a) by up to 15%, critical for sustained 300 mW operation.
