Product details
Overview
PUMH4,115 from Nexperia is a dual NPN resistor-equipped transistor (RET) in SOT363 (TSSOP6) package, featuring integrated 10 kΩ input bias resistors (R1), 50 V VCEO, 100 mA output current per transistor, and AEC-Q101 qualification. It functions as a compact, bias-resistor-integrated digital switch for low-current peripheral driving and IC input control in space-constrained automotive and industrial PCBs.
For engineers reviewing the PUMH4,115 datasheet, PUMH4,115 pinout, PUMH4,115 application, or PUMH4,115 equivalent, this device supports simplified BJT-based logic interfacing with reduced external component count, precise input threshold control (VI(on) = 1.1–1.7 V), and validated thermal performance on FR4 PCBs.
Technical Context
The PUMH4,115 integrates two independent NPN transistors, each with a dedicated 10 kΩ base-input resistor (R1) and open R2 configuration-enabling direct TTL/CMOS-level signal switching without external bias networks. Its dual-emitter-grounded topology (GND1/GND2) supports isolated channel operation and avoids shared emitter crosstalk.
Designed for digital switching-not linear amplification-it specifies VI(off) ≤ 0.58 V and VI(on) ≥ 1.1 V at defined test conditions, ensuring reliable turn-on/off behavior across temperature. The device's 150 °C max junction temperature and AEC-Q101 qualification confirm suitability for under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with margin. |
| IO | 100 mA - Continuous output current per transistor; sufficient for LED drivers, small relays, and logic-level translation. |
| R1 | 10 kΩ (7–13 kΩ range) - Integrated base bias resistor; eliminates need for external pull-up/pull-down, reducing BOM count by 2 resistors per channel. |
| VCE(sat) | ≤150 mV @ IC=10 mA, IB=0.5 mA - Low saturation voltage minimizes power loss and self-heating in switching mode. |
| hFE | ≥200 @ VCE=5 V, IC=1 mA - High DC current gain ensures robust drive capability even with marginal base current. |
| Ptot (per device) | 300 mW @ Tamb ≤25 °C - Total dissipation limit on FR4 PCB; defines maximum simultaneous channel loading before thermal derating. |
Pinout & Package
Package: SOT363 (TSSOP6), 2.1 mm × 1.25 mm × 0.95 mm body, 0.65 mm lead pitch, surface-mount plastic package with exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emitter connection for TR1; provides dedicated ground return path to isolate TR1 from TR2. |
| 2 | I1 | Base input for TR1; internally connected to 10 kΩ resistor (R1); accepts CMOS/TTL logic high to activate TR1. |
| 3 | O2 | Collector output for TR2; open-collector node for active-low switching or wired-OR logic implementation. |
| 4 | GND2 | Emitter connection for TR2; electrically separate from GND1, enabling dual-channel isolation. |
| 5 | I2 | Base input for TR2; internally connected to 10 kΩ resistor (R1); functionally identical to I1 but independent. |
| 6 | O1 | Collector output for TR1; complements O2 for dual independent low-side switch outputs. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors (R1 = 10 kΩ) | Eliminates 4 external resistors in dual-transistor logic interface circuits, reducing layout area and assembly cost. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM ≥2 kV), supporting under-hood deployment. |
| Low VCE(sat) (≤150 mV) | Reduces conduction loss and thermal stress during sustained switching, improving efficiency in battery-powered peripherals. |
| Dual isolated emitter grounds (GND1/GND2) | Prevents current coupling between channels, enabling independent control of two loads sharing no common emitter node. |
| VI(on)/VI(off) specification | Defined input thresholds (VI(on) ≥1.1 V, VI(off) ≤0.58 V) ensure predictable logic-level compatibility with 3.3 V and 5 V microcontrollers. |
Applications
| Automotive Door Module Driver | Industrial PLC Input Isolation |
|---|---|
Use Scenario: Driving window lock/unlock solenoids and mirror position LEDs in vehicle door modules where board space and component count are constrained. IC Role / Device Role / Timing Role: Dual low-side switch providing isolated 100 mA sink capability per channel, directly controlled by MCU GPIOs. Use Value: Replaces discrete BJT + resistor pairs, cutting PCB area by >30% and eliminating solder joint risks from four passive components. |
Use Scenario: Level-shifting and isolating 24 V field sensor inputs into 3.3 V PLC controller ADC or GPIO pins. IC Role / Device Role / Timing Role: Digital input conditioner converting industrial voltage levels to logic-compatible signals with built-in noise immunity. Use Value: VI(on)/VI(off) specs guarantee clean transition at 24 V input via voltage divider, avoiding false triggering in noisy factory environments. |
| USB-C Port Power Switch Control | IoT Sensor Node Wake-Up Interface |
Use Scenario: Enabling/disabling VBUS power paths in USB-C receptacles based on CC line detection logic. IC Role / Device Role / Timing Role: Dual-channel enable switch controlling back-to-back MOSFET gates or load switches in USB PD power routing. Use Value: Independent GND1/GND2 allows separate grounding of upstream/downstream power domains, meeting USB-C isolation requirements. |
Use Scenario: Waking ultra-low-power MCUs from deep sleep using mechanical switch or reed sensor inputs in battery-operated environmental sensors. IC Role / Device Role / Timing Role: Debounced, resistor-biased digital input buffer with low leakage (ICEO ≤5 µA @ 150 °C) preserving battery life. Use Value: 100 nA ICBO and 5 µA ICEO at max junction temperature minimize standby current drain over full automotive temperature range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN RET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSVDU2D12TZ | Same SOT363 package; R1 = 4.7 kΩ (lower input impedance); VCEO = 40 V; not AEC-Q101 qualified. | Limited to non-automotive industrial use due to lower voltage rating and absence of automotive qualification. | Select when lower VI(on) threshold (~0.8 V) is needed and 40 V rail margin suffices; avoid in automotive or 48 V systems. |
| PUMD4,115 | NPN/PNP complement; identical pinout and package; shares same R1 value and AEC-Q101 status; enables push-pull output stages. | Required for complementary output configurations (e.g., level-shifting with active-high/active-low pairs). | Choose when designing bidirectional signal interfaces or H-bridge pre-driver logic requiring matched NPN+PNP characteristics. |
Compared with NSVDU2D12TZ, PUMH4,115 offers higher voltage safety margin and automotive qualification; versus PUMD4,115, it provides matched dual-NPN topology ideal for parallel load switching rather than complementary drive.

FAQ
Is PUMH4,115 pin-compatible with PUMD4,115?
Yes-PUMH4,115 and PUMD4,115 share identical SOT363 (TSSOP6) pinout and mechanical footprint. Both have GND1/I1/O2/GND2/I2/O1 assignments. This enables drop-in substitution in layouts designed for either part, though electrical behavior differs due to NPN/NPN vs. NPN/PNP topology.
What is the maximum ambient temperature for continuous 100 mA operation per channel?
At 100 mA per channel (200 mA total device current), PUMH4,115 requires derating. With 300 mW total Ptot and Rth(j-a) = 416 K/W on FR4, junction temperature exceeds 150 °C above ~75 °C ambient. For continuous 100 mA/channel, limit ambient to ≤60 °C or reduce load current per channel.
Can R2 be externally connected, or is it permanently open?
R2 is permanently open (unconnected) inside the PUMH4,115 die-no internal connection exists. The datasheet explicitly states "R2 = open", and the internal schematic shows only R1 tied between I1/I2 and GND1/GND2. External connection to R2 is physically impossible and electrically undefined.
Does PUMH4,115 support 1.8 V logic input control?
No-VI(on) is specified as ≥1.1 V minimum, but typical turn-on occurs at 1.7 V. At 1.8 V supply, margin is insufficient for guaranteed activation across voltage tolerance, temperature, and process variation. Use ≥3.0 V logic sources or add external level-shifting for reliable operation.
