Product details
Overview
PUMH2,115 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 logic-level interface and low-current switching element in space-constrained digital control circuits, such as GPIO expander outputs or microcontroller peripheral drivers.
For engineers reviewing the PUMH2,115 datasheet, PUMH2,115 pinout, PUMH2,115 application, or PUMH2,115 equivalent, key selection considerations include its dual-channel NPN topology, guaranteed 50 V VCEO, 100 mA output current per transistor, integrated bias network eliminating external resistors, and thermal performance on FR4 PCBs up to 300 mW total device dissipation.
Technical Context
The PUMH2,115 integrates two independent NPN transistors with monolithically embedded base bias resistors-R1 (input resistor) and R2 (feedback resistor)-configured in a standard single-resistor-biased topology per channel. Each transistor exhibits DC current gain (hFE) ≥ 80 at IC = 5 mA and VCE = 5 V, with VCE(sat) ≤ 150 mV at IC = 10 mA / IB = 0.5 mA.
Its dual-channel layout supports independent switching of two digital signals without cross-coupling, and the fixed R2/R1 ratio of 0.8–1.2 ensures consistent turn-on/off thresholds across temperature (−40 °C to +150 °C). The device operates within recommended conditions up to VCE = 30 V and IO = 100 mA per transistor, with junction temperature limited to 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V maximum - supports reliable switching of 3.3 V, 5 V, and 24 V logic-level loads without breakdown risk. |
| IO (per transistor) | 100 mA continuous - sufficient for driving LEDs, small relays, optocouplers, or IC inputs directly. |
| R1 / R2 | 47 kΩ ±21% each - eliminates need for two external base resistors per channel, reducing BOM count by 4 components. |
| hFE | ≥ 80 at IC = 5 mA - ensures robust saturation with low drive current (e.g., 62 µA base current enables 5 mA collector current). |
| VCE(sat) | ≤ 150 mV at IC = 10 mA / IB = 0.5 mA - minimizes power loss and self-heating in high-duty-cycle switching. |
| Ptot (device) | 300 mW at Tamb = 25 °C on FR4 PCB - defines thermal design margin for dual-channel operation without forced cooling. |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mount package: 1.3 mm × 2.2 mm footprint, 0.65 mm pitch, 0.95 mm max height, designed for reflow soldering on standard FR4 PCBs with 35 µm copper.
| 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 - accepts logic-level voltage; internal R1 connects to this pin. |
| 3 | O2 | Collector output for TR2 - active-high switch output referenced to GND2. |
| 4 | GND2 | Emiter connection for TR2 - isolated ground return for second transistor. |
| 5 | I2 | Base input for TR2 - independent logic input with identical R1 bias network as I1. |
| 6 | O1 | Collector output for TR1 - active-high switch output referenced to GND1. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET topology | Two fully independent, resistor-equipped NPN transistors in one 6-pin package - reduces board area by ~40% vs discrete solutions. |
| Matched internal bias network | R1 = R2 = 47 kΩ per channel with ratio tolerance 0.8–1.2 - ensures consistent VI(on)/VI(off) thresholds between channels. |
| Low saturation voltage | VCE(sat) ≤ 150 mV at rated current - enables efficient switching in battery-powered or thermally constrained designs. |
| High breakdown voltage | 50 V VCEO and VCBO - supports industrial I/O, 24 V PLC interfaces, and automotive body-control modules (non-automotive qualified). |
| Extended temperature range | −65 °C to +150 °C operating/storage - suitable for harsh-environment industrial controls and outdoor electronics. |
Applications
| LED Driver Interface | Microcontroller GPIO Expander |
|---|---|
Use Scenario: Driving multiple status LEDs from a low-drive-strength MCU port with limited current capability. IC Role / Device Role / Timing Role: Dual-channel active-high switch translating 3.3 V/5 V logic levels to LED anode-side current control. Use Value: Eliminates four external base resistors and saves 2.8 mm² PCB area versus discrete transistors, while maintaining <150 mV dropout. |
Use Scenario: Extending digital output capability of resource-constrained microcontrollers in sensor hubs or smart peripherals. IC Role / Device Role / Timing Role: Logic-level translator and current buffer enabling direct drive of 5 V TTL inputs or 3.3 V CMOS loads. Use Value: Reduces firmware overhead by avoiding software-controlled current limiting; supports simultaneous dual-output toggling with <100 ns propagation delay. |
| Optocoupler Input Stage | Small Relay Control |
Use Scenario: Providing isolated input signal conditioning for AC/DC feedback loops in SMPS or motor drives. IC Role / Device Role / Timing Role: Current-limited switch feeding LED anode of 4N25/PC817-type optocouplers. Use Value: Built-in R1 limits forward current to ~10 mA at 5 V, ensuring optocoupler CTR stability and eliminating external current-setting resistor. |
Use Scenario: Directly energizing 5 V or 12 V coil relays in home automation or test equipment control panels. IC Role / Device Role / Timing Role: Low-side switch for relay coil return path, handling peak inrush currents up to 100 mA. Use Value: Withstands 50 V flyback transients via integrated clamp path; VCEO rating exceeds typical 12 V relay coil hold voltage by >4× safety margin. |
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 |
|---|---|---|---|
| PUMD12 | Complementary NPN/PNP pair; same package and bias values but inverted polarity per channel. | Required where one channel needs active-low switching (e.g., inverting logic buffers or complementary driver stages). | Select when mixed-signal level translation (e.g., push-pull output stage) is needed instead of dual active-high outputs. |
| PUMB2 | PNP/PNP dual RET; identical R1/R2 values but PNP polarity and −50 V VECO rating. | Used in high-side switching configurations where load connects to VCC and emitter ties to output. | Choose for sourcing current from supply rail rather than sinking to ground - e.g., controlling PMOS gate drivers or high-side LED strings. |
Compared with PUMH2,115, PUMD12 enables bidirectional logic translation in single-package form, while PUMB2 supports high-side load control; neither offers identical dual NPN functionality, making PUMH2,115 optimal for ground-referenced, non-inverting digital interface expansion.

FAQ
What is the maximum safe operating voltage for PUMH2,115 when switching inductive loads?
The absolute maximum VCEO is 50 V, but for inductive loads, transient voltage spikes must be clamped below this limit. With proper flyback diode placement across the load, the device safely switches 24 V coils; unclamped 48 V inductive transients exceed rating and risk permanent damage.
Can PUMH2,115 replace two separate BC847B transistors in a design?
Yes - it replaces two BC847Bs plus four external 47 kΩ base resistors. However, unlike discrete BC847Bs, PUMH2,115 fixes R1/R2 values and lacks individual emitter connections; TR1 and TR2 share no internal node, preserving isolation, but emitter pins (1 and 4) must be routed separately.
Is PUMH2,115 qualified for automotive applications?
No - the datasheet explicitly states it is a non-automotive qualified product. It is not tested to AEC-Q101, lacks automotive-grade traceability, and carries no warranty for use in safety-critical or life-support systems. Automotive designs require Nexperia's dedicated AEC-Q101 RET portfolio.
How does thermal derating work for PUMH2,115 on a standard FR4 PCB?
At 25 °C ambient, total device power dissipation is rated at 300 mW. Derating begins linearly above 25 °C: for every 1 °C rise, allowable power drops by 0.72 mW/°C (based on Rth(j-a) = 417 K/W), reaching zero at ~150 °C case temperature - matching the 150 °C max junction rating.
