Product details
Overview
PUMB11 from Nexperia is a PNP/PNP resistor-equipped double transistor (RET) in SOT363-3 (SC-88) package, rated for −50 V VCEO, −100 mA IO, with integrated R1 = 10 kΩ and R2 = 10 kΩ bias resistors. It functions as a dual low-side switch or logic-level translator in compact digital interface circuits, commonly used in I/O buffering and peripheral control on space-constrained PCBs.
For engineers reviewing the PUMB11 datasheet, PUMB11 pinout, PUMB11 application, or PUMB11 equivalent, this device supports simplified BOM reduction in discrete logic interfacing, offers verified thermal performance up to 150 °C junction temperature, and delivers consistent −1.8 V typical VI(on) and <100 mV VCE(sat) at −10 mA load - critical for 3.3 V/5 V mixed-voltage system design.
Technical Context
The PUMB11 integrates two matched PNP transistors with monolithically embedded base bias resistors, eliminating external pull-up networks. Each transistor features independent emitter-grounded configuration (GND1/GND2), enabling isolated channel operation without shared emitter nodes.
Its R2/R1 ratio of 0.8–1.2 ensures stable current gain control across temperature (−40 °C to +150 °C), while the 3 pF collector capacitance and 180 MHz fT support reliable switching up to ~10 MHz in digital enable/disable applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage with open base; enables use in 36 V industrial bus interfaces. |
| IO | −100 mA: Continuous output current per transistor; sufficient for driving LED indicators or small relays. |
| R1 | 10 kΩ ±30%: Integrated input bias resistor; sets base current without external components. |
| VCE(sat) | ≤ −100 mV at IC = −10 mA, IB = −0.5 mA: Ensures low conduction loss in active-low switching paths. |
| hFE | ≥30 at VCE = −5 V, IC = −5 mA: Guarantees adequate current amplification for logic-level signal inversion. |
| fT | 180 MHz typical: Supports fast edge transitions in clock gating or pulse-width modulation control signals. |
| Ptot (per device) | 300 mW at Tamb = 25 °C: Enables dual-channel operation within thermal limits on standard FR4 PCBs. |
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-J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emitter connection for TR1; provides dedicated low-impedance return path for first transistor. |
| 2 | I1 | Base input for TR1; internally connected to R1 and R2; accepts TTL/CMOS-compatible logic levels. |
| 3 | O2 | Collector output for TR2; active-low switching node; requires external pull-up for open-collector behavior. |
| 4 | GND2 | Emitter connection for TR2; electrically isolated from GND1 to support dual independent loads. |
| 5 | I2 | Base input for TR2; identical bias network as I1; enables synchronous or independent channel control. |
| 6 | O1 | Collector output for TR1; complements O2 for dual-signal routing; shares same electrical specs as O2. |
Key Features
| Feature | Design Value |
|---|---|
| Dual PNP RET architecture | Two fully isolated PNP transistors with matched R1/R2 networks reduce layout area by >40% vs. discrete solutions. |
| Integrated 10 kΩ bias resistors | Eliminates four external resistors per channel, cutting pick-and-place cycles and BOM cost in high-volume consumer PCBs. |
| −100 mA per channel rating | Supports direct drive of optocoupler inputs, small solenoids, or status LEDs without additional driver stages. |
| Low VCE(sat) (≤ −100 mV) | Minimizes power dissipation in always-on control lines, extending battery life in portable instrumentation. |
| 150 °C maximum junction temperature | Enables deployment in under-hood automotive modules or enclosed industrial enclosures without forced cooling. |
Applications
| LED Status Indicators | Microcontroller GPIO Expanders |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual PNP RET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PUMD3 | NPN/PNP complement; single NPN + single PNP pair; different pinout (I1/O1/GND1/I2/O2/GND2). | Required where mixed-signal logic translation (e.g., 5 V → 3.3 V level shift) is needed alongside sinking. | Select when circuit requires one NPN and one PNP channel with shared ground reference. |
| PUMH11 | NPN/NPN version; identical package and bias resistor values but opposite polarity; VCEO = +50 V. | Suitable for high-side switching or sourcing applications where positive rail control is required. | Choose for sourcing loads from VCC rather than sinking to GND, e.g., driving NMOS gate drivers. |
Compared with PUMD3 and PUMH11, the PUMB11 uniquely supports dual independent PNP sinking with separate emitter returns - essential for isolated load control in fault-tolerant industrial I/O modules where channel crosstalk must be avoided.

FAQ
What is the maximum allowable continuous current per channel?
The PUMB11 supports −100 mA continuous output current per transistor under Tamb ≤ 25 °C with proper PCB copper area. Derating is required above 25 °C ambient: power dissipation drops linearly to zero at 150 °C junction temperature, per the 417 K/W per-device thermal resistance specification.
Can PUMB11 be used in 5 V logic systems with 24 V loads?
Yes - the −50 V VCEO rating allows safe operation with 24 V loads when used as a grounded-emitter switch. An external current-limiting resistor must be placed between the 24 V rail and the collector (O1/O2), sized to limit IC to ≤ −100 mA under worst-case VCE(sat) conditions.
Are the two transistors electrically isolated from each other?
Yes - GND1 and GND2 are separate terminals with no internal connection; each transistor operates with its own emitter reference. This enables true galvanic isolation between channels, supporting differential signaling or independent load grounding schemes.
Does PUMB11 require external base resistors?
No - R1 and R2 are monolithically integrated (10 kΩ each). External base resistors are unnecessary for standard logic-level drive; however, a series resistor may be added to I1/I2 if driving from high-voltage sources (>5 V) to limit input current per VI absolute maximum rating of −40 V.
