Product details
Overview
PUMH2/DG/B3,115 from Nexperia is an NPN/NPN dual resistor-equipped transistor (RET) in SOT363 (SC-88) surface-mount package, featuring integrated 47 kΩ input bias resistors (R1 = R2 = 47 kΩ) and AEC-Q101 qualification. It delivers 100 mA per transistor output current, supports 50 V collector-emitter voltage, and simplifies digital interface design by eliminating external base resistors in low-current peripheral driver applications.
For engineers reviewing the PUMH2/DG/B3,115 datasheet, PUMH2/DG/B3,115 pinout, PUMH2/DG/B3,115 application, or PUMH2/DG/B3,115 equivalent, this device serves as a space-optimized, automotive-grade replacement for discrete NPN transistor pairs in logic-level signal translation, microcontroller I/O buffering, and LED/relay driver circuits where board area and assembly cost are critical.
Technical Context
This dual RET integrates two matched NPN transistors with identical on-chip bias networks (R1 = 47 kΩ, R2 = 47 kΩ, R2/R1 ratio = 1.0 ±0.2), enabling direct connection to CMOS/TTL logic without external pull-up or base resistors. Each transistor operates independently with open-base VCEO = 50 V and IO = 100 mA rating.
The device uses a common-emitter configuration per channel, with dedicated GND pins (Pin 1 & Pin 4) and cross-coupled base/collector assignments (Pin 2→TR1 base, Pin 6→TR1 collector; Pin 5→TR2 base, Pin 3→TR2 collector), supporting bidirectional signal routing in compact logic interface designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage under open-base condition; enables use in 24 V industrial control and 12 V automotive signal chains. |
| IO | 100 mA - Continuous DC output current per transistor; sufficient for driving LEDs, small relays, or logic inputs without external current limiting. |
| R1 / R2 | 47 kΩ ±28 kΩ - Integrated base-input resistors eliminate need for two external 47 kΩ resistors per channel, reducing BOM count and PCB footprint. |
| hFE | 80 min at IC = 5 mA, VCE = 5 V - Ensures reliable saturation with low base drive current (e.g., 62.5 µA base current yields 5 mA collector current). |
| VCE(sat) | 150 mV max at IC = 10 mA, IB = 0.5 mA - Low saturation voltage minimizes power loss and heat generation in switching applications. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing; suitable for under-hood and infotainment modules. |
Pinout & Package
SOT363 (SC-88) 6-pin ultra-small flat-lead package (2.2 mm × 1.35 mm × 0.95 mm), optimized for high-density PCB layouts and reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND (emitter of TR1) | Common emitter reference for first transistor; must be connected to system ground for proper biasing and current return path. |
| 2 | Input (base of TR1) | Logic-level input node for TR1; internal 47 kΩ resistor connects to Pin 1 (GND), enabling direct CMOS/TTL drive. |
| 3 | Output (collector of TR2) | Active-low switched output for second transistor; sinks current when TR2 is biased via Pin 5. |
| 4 | GND (emitter of TR2) | Independent emitter reference for second transistor; allows separate grounding or local decoupling if needed. |
| 5 | Input (base of TR2) | Logic-level input node for TR2; internal 47 kΩ resistor connects to Pin 4 (GND), supporting independent channel control. |
| 6 | Output (collector of TR1) | Active-low switched output for first transistor; sinks current when TR1 is biased via Pin 2. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET architecture | Two fully independent NPN transistors with matched internal bias resistors reduce layout complexity and improve channel-to-channel consistency in interface circuits. |
| 47 kΩ integrated bias resistors | Eliminates four external resistors per device, cutting pick-and-place cycle time and minimizing solder joint failure risk in high-volume SMT assembly. |
| 100 mA per-channel output | Supports direct drive of standard LEDs (20 mA), small signal relays (≤75 mA), and logic inputs without external amplification stages. |
| AEC-Q101 qualification | Validated for automotive environments including −40 °C to +125 °C operation, thermal shock, and humidity testing-enabling use in ADAS sensor interfaces and body control modules. |
| SOT363 package | 0.65 mm pitch, 2.2 mm × 1.35 mm footprint saves >60% board area vs. SO-8 equivalents while maintaining compatibility with standard 0.4 mm stencil apertures. |

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 |
|---|---|---|---|
| NSVD2T2228WT1G | Single-channel NPN RET (SOT-363), R1 = 22 kΩ, R2 = 22 kΩ; no dual topology. | Requires two devices to match PUMH2 functionality; higher BOM count and layout area. | Select when single-channel isolation is preferred or when lower bias resistance (22 kΩ) suits higher-speed switching needs. |
| EMX11T2R | NPN/PNP complementary RET pair (SOT-363); R1 = 10 kΩ, R2 = 10 kΩ; different polarity and bias values. | Enables push-pull output stages but lacks dual-NPN symmetry; unsuitable for identical-channel logic buffering. | Choose for complementary output drivers or when 10 kΩ bias supports faster edge rates in high-frequency clock distribution. |
Compared with NSVD2T2228WT1G and EMX11T2R, PUMH2/DG/B3,115 uniquely delivers matched dual-NPN functionality with 47 kΩ biasing in one SOT363 package-optimizing for space-constrained, automotive-grade digital interface applications where channel symmetry and reduced assembly steps are critical.

FAQ
What is the maximum operating temperature for PUMH2/DG/B3,115?
The device supports ambient temperatures from −65 °C to +150 °C and junction temperatures up to 150 °C. Its thermal resistance (Rth(j-a)) is 417 K/W per device on FR4 PCB, meaning it dissipates up to 300 mW at 25 °C ambient before reaching thermal limit-suitable for under-hood automotive locations with proper copper pour.
Can PUMH2/DG/B3,115 be used with 1.8 V logic inputs?
Yes. VI(on) is specified at 1.6 V typical (min 3 V at IC = 2 mA), but actual turn-on behavior shows functional switching down to ~1.2 V due to hFE >80 and low VCE(sat). For robust 1.8 V operation, verify with IC/IB ≥20 margin in final design; no external level shifter required.
Is the SOT363 package lead-free and RoHS compliant?
Yes. PUMH2/DG/B3,115 uses a lead-free, halogen-free SOT363 package qualified to JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) and compliant with EU RoHS Directive 2011/65/EU and REACH SVHC regulations.
How does the R2/R1 ratio affect circuit performance?
The R2/R1 ratio of 0.8–1.2 ensures consistent base current division between input and feedback paths, stabilizing DC bias points and improving immunity to process variation. This tight tolerance maintains predictable VI(on)/VI(off) thresholds across temperature and lot, critical for noise-immune digital interfacing.
