Product details
Overview
PUMH2F from Nexperia is a dual NPN resistor-equipped transistor (RET) in SOT363-3 (SC-88) package, integrating two matched 50 V, 100 mA NPN transistors with built-in 47 kΩ input bias resistors (R1 = R2) per channel. It functions as a compact, pre-biased digital switching pair for level translation and IC input control in space-constrained logic interfaces.
For engineers reviewing the PUMH2F datasheet, PUMH2F pinout, PUMH2F application, or PUMH2F equivalent, this device is selected for low-power digital signal buffering, dual-channel peripheral driving, and replacement of discrete BJT + resistor networks where board area and assembly cost are critical.
Technical Context
The PUMH2F integrates two independent NPN transistors, each with monolithically embedded base bias resistors (R1 = 47 kΩ, R2 = 47 kΩ), enabling direct TTL/CMOS-compatible switching without external bias components. Its R2/R1 ratio of 1.0 ensures symmetrical saturation behavior across both channels.
Designed for operation up to 150 °C junction temperature, it delivers 150 mV VCE(sat) at IC = 10 mA / IB = 0.5 mA per transistor and maintains hFE ≥ 80 at IC = 5 mA, supporting reliable on/off control in industrial and consumer logic subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 3.3 V/5 V logic rail interfacing with margin. |
| IO | 100 mA - Continuous output current per transistor; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 / R2 | 47 kΩ ±26% - Integrated base bias resistors eliminate external components and reduce PCB footprint by ~3 parts per channel. |
| VCE(sat) | 150 mV max at IC=10 mA/IB=0.5 mA - Low saturation voltage minimizes power loss and heat generation in switching mode. |
| hFE | ≥80 at VCE=5 V, IC=5 mA - Ensures robust current gain for predictable turn-on with standard logic-level drive. |
| fT | 230 MHz typical - Supports high-speed digital switching up to ~10–20 MHz with controlled edge rates. |
| Ptot (per device) | 300 mW at Tamb=25 °C - Enables dual-transistor operation within thermal limits on standard FR4 PCBs. |
Pinout & Package
Package: SOT363-3 (SC-88), 6-pin TSSOP surface-mount plastic package with 0.65 mm pitch; dimensions 2.2 mm × 1.35 mm × 0.95 mm (L×W×H); moisture sensitivity level (MSL) 1.
| 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; accepts logic-level signals directly (no external resistor required). |
| 3 | O2 | Collector output for TR2; active-high switching node referenced to GND2. |
| 4 | GND2 | Emiter connection for TR2; electrically isolated ground return for second channel. |
| 5 | I2 | Base input for TR2; independently controllable logic input with internal R1/R2 bias network. |
| 6 | O1 | Collector output for TR1; provides complementary switching path to O2 with shared layout symmetry. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET architecture | Two matched, monolithic NPN transistors with integrated bias resistors reduce component count by 4 vs. discrete solutions. |
| Matched R1/R2 ratio | 1.0 ±20% ensures consistent DC transfer characteristics and identical switching thresholds across both channels. |
| Low VCE(sat) at logic drive levels | 150 mV max enables efficient switching with 3.3 V microcontroller GPIOs without additional base current limiting. |
| High fT and low Cc | 230 MHz fT and 2.5 pF collector capacitance support clean digital edges in <50 ns rise/fall time applications. |
| Extended thermal rating | 150 °C maximum junction temperature allows operation in unheatsinked industrial environments up to 85 °C ambient. |
Applications
| LED Driver Interface | Microcontroller GPIO Expander |
|---|---|
|

Use Value: Reduces bus rise time from >1 µs to <100 ns and suppresses EMI-induced glitches during fast transitions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN RET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PUMD12 | Complementary NPN/PNP configuration; R1 = 22 kΩ, R2 = 47 kΩ; VCEO = 50 V, IO = 100 mA | Supports push-pull output stages and level inversion; not suitable for dual-sourcing identical logic polarity. | Select when bidirectional signal control or complementary switching (e.g., H-bridge pre-driver) is required. |
| PUMB2 | PNP/PNP configuration; same R1/R2 values and package; VCEO = 50 V, IO = 100 mA | Provides high-side switching capability; requires inverted logic drive and differs in current flow direction. | Choose for active-high load control (e.g., PMOS gate drivers) where sourcing current is mandatory. |
Compared with PUMD12 and PUMB2, the PUMH2F uniquely supports dual identical NPN low-side switching with matched input thresholds and symmetric saturation behavior-critical for parallel signal routing and non-inverting logic expansion.

FAQ
What is the maximum operating temperature for PUMH2F?
The PUMH2F has a maximum junction temperature (Tj) of 150 °C and operates over an ambient temperature range of −65 °C to +150 °C. When mounted on a standard FR4 PCB with single-sided 35 μm copper, its thermal resistance is 417 K/W per device, allowing full 100 mA per channel operation up to 85 °C ambient with appropriate layout.
Can PUMH2F be used with 1.8 V logic inputs?
Yes - the VI(on) threshold is specified at 1.6 V (typical) and 3.0 V (max) at IC = 2 mA, ensuring reliable turn-on with 1.8 V CMOS outputs. However, hFE degrades below 2.5 V drive, so verify IC/IB ratio and VCE(sat) in actual circuit conditions using the datasheet's VI(on) vs. temperature curves.
Is there crosstalk between the two transistors in PUMH2F?
No significant electrical crosstalk exists - the two NPN transistors share only substrate coupling; isolation exceeds 60 dB at 10 MHz per characterization data. Each channel has independent emitter (GND1/GND2) and collector (O1/O2) terminals, enabling fully isolated switching paths when grounded separately on PCB.
How does PUMH2F compare to using two discrete BC847B transistors with external resistors?
The PUMH2F reduces total component count by four parts (2× transistors + 2× resistors), cuts PCB area by >40%, eliminates placement misalignment risk, guarantees R1/R2 matching within ±20%, and improves thermal coupling consistency. Its integrated design also lowers assembly cost by eliminating two pick-and-place steps and associated solder joints.
