Product details
Overview
PUMH11 from Nexperia is a resistor-equipped double NPN transistor (RET) in SOT363-3 (SC-88) package, rated for 50 V VCEO, 100 mA output current per transistor, with integrated bias resistors R1 = R2 = 10 kΩ. It functions as a dual low-side switch or digital logic interface driver in space-constrained PCBs, commonly used to drive LED segments, GPIO expanders, and level-shifting inputs in portable microcontroller systems.
For engineers reviewing the PUMH11 datasheet, PUMH11 pinout, PUMH11 application, or PUMH11 equivalent, this page delivers verified electrical parameters, validated dual-transistor pin mapping, thermal derating curves, and direct alternatives for discrete logic-level switching designs requiring reduced BOM count and simplified base-drive circuitry.
Technical Context
The PUMH11 integrates two matched NPN transistors with on-chip base biasing: each channel includes a 10 kΩ input resistor (R1) and a 10 kΩ feedback resistor (R2), yielding an R2/R1 ratio of 1.0 (±0.2). This configuration enables direct TTL/CMOS-compatible switching without external base resistors.
Each transistor operates with VCEO = 50 V, IO = 100 mA, VCE(sat) ≤ 150 mV at IC = 10 mA / IB = 0.5 mA, and hFE ≥ 30 at VCE = 5 V and IC = 5 mA - supporting robust digital on/off control across industrial temperature range (−65 °C to +150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - maximum collector-emitter voltage before breakdown; supports 24 V rail interfacing and transient-tolerant I/O buffering. |
| IO | 100 mA per transistor - sufficient to drive small relays, LEDs, or logic inputs without external amplification. |
| R1 | 10 kΩ ±30% - built-in base input resistor; eliminates need for discrete pull-up/base resistor in standard logic-driven configurations. |
| R2/R1 | 1.0 ±0.2 - defines internal feedback ratio; ensures stable saturation and predictable turn-off behavior under varying temperature. |
| VCE(sat) | ≤150 mV at IC=10 mA/IB=0.5 mA - minimizes conduction loss and self-heating in continuous-duty digital switching. |
| fT | 230 MHz typical - enables reliable operation up to high-speed digital switching (e.g., PWM up to ~10 MHz with margin). |
| Ptot (per device) | 300 mW at Tamb = 25 °C - sets thermal design limit for dual-channel operation on FR4 PCB with standard footprint. |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mounted package: 2.2 mm × 1.35 mm × 0.95 mm body height, 0.65 mm lead pitch, gull-wing leads, tape-and-reel packaging compatible with automated placement.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1; common reference node for first transistor channel. |
| 2 | I1 | Base input for TR1; accepts CMOS/TTL logic-level signals directly via internal R1. |
| 3 | O2 | Collector output for TR2; active-low sink output when TR2 is switched on. |
| 4 | GND2 | Emiter connection for TR2; independent ground return path for second channel. |
| 5 | I2 | Base input for TR2; electrically isolated from I1; enables independent dual-channel control. |
| 6 | O1 | Collector output for TR1; provides second independent active-low sink output. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET architecture | Two fully independent, resistor-equipped NPN transistors in one ultra-small SOT363-3 package - reduces board area by >40% vs. discrete dual-transistor solutions. |
| Integrated bias network | R1 = R2 = 10 kΩ per channel with ±30% tolerance - eliminates four external resistors and associated layout routing, lowering assembly cost and test complexity. |
| Guaranteed saturation | VCE(sat) ≤ 150 mV at IC/IB = 20 - ensures reliable low-loss switching even under worst-case hFE and temperature conditions. |
| Thermal robustness | Rth(j-a) = 417 K/W (per device on FR4) - supports sustained 100 mA dual-channel operation up to +85 °C ambient with no forced airflow. |
Applications
| LED Segment Driver | Microcontroller GPIO Expander |
|---|---|
|
Use Scenario: Driving 7-segment LED displays in handheld instrumentation where PCB space and component count are constrained. IC Role / Device Role / Timing Role: Dual low-side sink driver - each transistor independently controls one segment or digit cathode. Use Value: Eliminates need for eight discrete base resistors and two transistors; reduces netlist complexity and improves solder joint reliability. |
Use Scenario: Extending limited MCU GPIOs to manage multiple peripheral enable lines (e.g., sensors, ADCs, memory chips) in battery-powered edge nodes. IC Role / Device Role / Timing Role: Digital signal buffer and level translator - translates 1.8 V/3.3 V logic outputs to 5 V-tolerant sink loads. Use Value: Enables direct connection to 5 V peripherals without level-shifter ICs; supports <10 ns propagation delay due to fT = 230 MHz. |
| Logic-Level Interface | Low-Power Relay Driver |
|
Use Scenario: Interfacing FPGA I/O banks with legacy 5 V logic systems in industrial PLC modules. IC Role / Device Role / Timing Role: Bidirectional voltage translation assistant - used as active pull-down with external pull-up for open-drain compatibility. Use Value: VI(on) = 1.8 V min and VI(off) = 1.1 V max ensure clean logic threshold discrimination across −40 °C to +100 °C. |
Use Scenario: Driving miniature 5 V/10 mA reed relays in smart home control panels with strict power budget limits. IC Role / Device Role / Timing Role: Low-power coil driver - provides controlled 100 mA sink current with <150 mV dropout to minimize relay coil heating. Use Value: Ptot = 300 mW allows dual-relay actuation simultaneously without thermal throttling on standard FR4. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PUMD3 | NPN/PNP complement; single R1 = 10 kΩ, no R2; VCEO = 50 V, IO = 100 mA | Supports complementary push-pull output stages; not suitable for dual-sink-only topologies. | Select when driving both high- and low-side loads from same control signal pair. |
| PUMB11 | PNP/PNP RET; R1 = R2 = 10 kΩ; VECO = 50 V, IO = 100 mA | Provides dual high-side sourcing; requires inverted logic drive and different bias polarity. | Choose for active-high output configurations where load connects to VCC rather than GND. |
Compared with PUMD3 and PUMB11, the PUMH11 uniquely supports dual identical NPN sink channels with matched R1/R2 networks - enabling symmetrical, non-inverting digital control without redesigning PCB layout or firmware logic polarity.

FAQ
What is the maximum safe operating current per channel of the PUMH11?
The absolute maximum output current per transistor is 100 mA, as defined in IEC 60134 limiting values. Continuous operation at this level requires adherence to the per-device 300 mW power dissipation limit and proper PCB thermal relief - e.g., minimum 1 cm² copper pour per GND pin on FR4. Derating is required above 25 °C ambient per Fig. 1.
Can PUMH11 be used in linear amplifier mode?
No - the PUMH11 is characterized and qualified only for switching operation. Its built-in resistors fix the base bias point, and hFE is specified only at DC switching conditions (IC = 5 mA). Small-signal gain (fT) is provided for switching speed validation, not analog amplification linearity or distortion performance.
How does the R2/R1 ratio affect switching behavior?
An R2/R1 ratio of 1.0 provides negative feedback that stabilizes the transistor's saturation state against hFE variation and temperature drift. This ensures consistent VCE(sat) and prevents thermal runaway during sustained conduction - critical for reliability in always-on indicator or status driver applications.
Is PUMH11 automotive-qualified?
No - the PUMH11 is not automotive-qualified. The datasheet explicitly states it is "non-automotive qualified" and lacks AEC-Q101 stress testing, extended temperature validation beyond 150 °C junction, or zero-defect manufacturing traceability required for automotive use. It is intended for industrial, consumer, and computing applications.
