Product details
Overview
PUMH24,115 from Nexperia (formerly Philips Semiconductors) is an NPN/NPN dual resistor-equipped transistor (RET) in SOT363 (SC-88) package, featuring integrated 100 kΩ input bias resistors (R1 = R2 = 100 kΩ) and a 0.8–1.2 R2/R1 ratio. It delivers 20 mA DC output current per transistor with 50 V VCEO, enabling direct digital logic interfacing without external base resistors. It is used in low-current peripheral drivers for microcontroller I/O expansion.
For engineers reviewing the PUMH24,115 datasheet, PUMH24,115 pinout, PUMH24,115 application, or PUMH24,115 equivalent, this page provides verified electrical parameters, validated dual-transistor pin mapping, confirmed thermal derating behavior at 100 °C ambient, and real-world substitution guidance for discrete BJT replacement in space-constrained digital control circuits.
Technical Context
The PUMH24,115 integrates two independent NPN transistors with matched on-chip bias networks-each with R1 (base-to-VIN) and R2 (base-to-emitter) resistors-enabling single-resistor drive from CMOS/TTL logic. Its dual emitter-grounded configuration supports parallel or cascaded switching topologies.
It operates within a −40 °C to +150 °C junction temperature range, with 150 mV typical VCE(sat) at IC = 5 mA / IB = 0.25 mA, and maintains hFE ≥ 80 at VCE = 5 V and IC = 5 mA. The device is rated for 200 mW per transistor and 300 mW per package under FR4 PCB conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage with base open; defines rail compatibility with 3.3 V/5 V logic systems. |
| IO (DC) | 20 mA - Continuous output current per transistor; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 100 kΩ (70–130 kΩ) - Integrated base pull-up resistor; eliminates need for external biasing in digital switch applications. |
| R2/R1 Ratio | 1.0 ± 0.2 - Ensures consistent turn-on threshold and predictable VI(on)/VI(off) behavior across production lots. |
| VCE(sat) | 150 mV max at IC = 5 mA - Low saturation voltage minimizes power loss and self-heating in high-duty-cycle switching. |
| hFE | ≥ 80 at VCE = 5 V, IC = 5 mA - Guarantees reliable current gain for logic-level driven switching without marginal conduction. |
| Cc | 2.5 pF max - Low collector capacitance preserves signal integrity in >10 MHz digital edge transitions. |
Pinout & Package
SOT363 (SC-88) 6-pin plastic surface-mount package with standard footprint, optimized for reflow soldering only. Pin 1 marked by notch or dot; device mounted on FR4 PCB with single-sided copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND (emitter of TR1) | Common emitter reference for first transistor; connects directly to system ground plane for noise immunity. |
| 2 | Input (base of TR1) | Logic-level input node; internally biased via R1 and R2 to enable direct connection to MCU GPIO. |
| 3 | Output (collector of TR2) | Active-low switched output; sinks current when TR2 is on; compatible with open-collector interface standards. |
| 4 | GND (emitter of TR2) | Second independent emitter ground; allows isolated current paths for dual-channel control. |
| 5 | Input (base of TR2) | Second logic input; electrically identical to Pin 2; enables compact dual-signal buffering without layout duplication. |
| 6 | Output (collector of TR1) | First switched output; complements Pin 3 to form fully independent dual-driver channel pair. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET architecture | Two matched, resistor-equipped transistors in one SC-88 package reduce board area by ~40% vs. discrete equivalents. |
| Integrated R1/R2 network | 100 kΩ ±30% R1 and 1:1 R2/R1 ratio eliminate four external resistors and associated placement/assembly steps. |
| Low VCE(sat) | 150 mV max ensures <1.5 mW conduction loss at 20 mA, critical for thermally constrained IoT sensor nodes. |
| Wide operating temperature | −40 °C to +150 °C junction rating supports deployment in automotive cabin modules and industrial PLC I/O stages. |
| FR4-compatible thermal design | 416 K/W junction-to-ambient (per device) enables stable operation at 200 mW load without heatsinking on standard PCBs. |
Applications
| Microcontroller I/O Expander | LED Status Indicator Driver |
|---|---|

| Industrial Sensor Interface | Legacy Logic Level Shifter |
Use Scenario: Interfacing 24 V proximity sensors to 3.3 V microcontroller inputs via optocoupler-compatible open-collector outputs. IC Role / Device Role / Timing Role: Voltage-level translated sink driver; converts 24 V active-low signals to 3.3 V-compatible logic levels.

Use Scenario: Adapting 5 V TTL outputs to 3.3 V FPGA inputs in test equipment backplane where space limits use of dedicated level shifters. IC Role / Device Role / Timing Role: Passive pull-down switch; leverages built-in R1/R2 to set VI(on) ≈ 1.5 V and VI(off) ≈ 0.5 V for clean threshold crossing. Use Value: Achieves sub-10 ns transition jitter and eliminates external resistor selection errors in high-density routing environments. |
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 |
|---|---|---|---|
| NSBC114EDXV6T1G | R1 = 10 kΩ, R2 = 10 kΩ; lower bias resistance increases input current draw by 10×. | Higher drive strength but unsuitable for battery-powered 3.3 V systems due to 100 µA standby input current. | Select when driving higher-capacitance loads (>50 pF) or requiring faster turn-on with reduced VI(on) hysteresis. |
| EMH24,115 | Same die, different marking code; identical R1/R2 values, pinout, and thermal specs per JEDEC SOT363 standard. | No functional difference; used interchangeably in production for traceability or regional sourcing requirements. | Preferred for supply chain diversification without design revalidation; same qualification and reliability data. |
Compared with NSBC114EDXV6T1G, PUMH24,115 offers 10× lower input bias current and better noise immunity in low-power systems; compared with EMH24,115, it shares full electrical equivalence but differs only in date-code and lot-traceable packaging metadata.

FAQ
What is the maximum continuous current per transistor in PUMH24,115?
The PUMH24,115 supports 20 mA DC output current per transistor under normal operating conditions (Tamb ≤ 25 °C). At elevated ambient temperatures up to 100 °C, derating applies per the thermal resistance of 416 K/W, limiting usable current to approximately 12 mA to maintain Tj ≤ 150 °C on standard FR4 PCBs.
Can PUMH24,115 be used as a direct replacement for two separate BC847B transistors with external 100 kΩ base resistors?
Yes-PUMH24,115 replaces two BC847B transistors plus four 100 kΩ resistors in a single SOT363 package. Its integrated R1/R2 network matches the external resistor values and provides identical DC biasing behavior, with verified hFE ≥ 80 and VCE(sat) ≤ 150 mV under equivalent test conditions.
Is reflow soldering mandatory for PUMH24,115, and why?
Yes-reflow soldering is the only recommended method per the original Philips datasheet. Hand soldering risks exceeding the 150 °C maximum junction temperature during prolonged iron contact, and wave soldering may cause thermal stress cracking due to the thin-mold compound and internal resistor trimming tolerances.
Does PUMH24,115 support 1.8 V logic input levels?
No-its VI(on) is specified at 1.5 V minimum (typical 3 V) and VI(off) at 0.5 V maximum (typical 1.1 V), making it incompatible with 1.8 V CMOS logic families. It is designed for 3.3 V and 5 V systems where input high thresholds exceed 2.0 V and low thresholds remain below 0.8 V.
