Product details
Overview
PUMH10Z from Nexperia is a dual NPN resistor-equipped transistor (RET) in SOT363-3 (SC-88) package, rated for 50 V VCEO, 100 mA output current per transistor, with integrated R1 = 2.2 kΩ and R2 = 47 kΩ bias resistors; used for low-current digital signal buffering and IC input control in space-constrained logic interfaces.
For engineers reviewing the PUMH10Z datasheet, PUMH10Z pinout, PUMH10Z application, or PUMH10Z equivalent, this page delivers verified electrical parameters, validated dual-transistor pin mapping, confirmed thermal derating behavior on FR4 PCB, and direct alternatives for discrete logic-level translation and peripheral driver replacement.
Technical Context
The PUMH10Z integrates two matched NPN transistors with monolithically embedded base bias networks-R1 connects input to base, R2 connects base to emitter-enabling single-resistor drive without external components. Each transistor operates independently with open-base VCEO = 50 V and IO = 100 mA rating.
It functions as a digitally controlled switch with VI(on) = 0.75 V (typ) at IC = 5 mA and VCE(sat) ≤ 100 mV (max), supporting TTL/CMOS-compatible input thresholds and low-loss switching in 3.3 V and 5 V logic domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V maximum collector-emitter voltage per transistor; supports rail-to-rail switching up to 5 V logic with margin for transient spikes. |
| IO | 100 mA continuous output current per transistor; sufficient for driving LED indicators, small relays, or logic inputs without external current gain staging. |
| R1 | 2.2 kΩ ±30% input bias resistor; sets base current directly from logic-high source, eliminating need for discrete pull-up/base resistor. |
| R2/R1 ratio | 21 (typ), range 17–26; defines internal feedback ratio for stable saturation and predictable turn-off behavior under varying temperature. |
| Ptot (per device) | 300 mW at Tamb = 25 °C on FR4 PCB; enables dual-transistor operation within thermal limits without heatsinking in compact consumer PCB layouts. |
| fT | 230 MHz typical transition frequency; ensures adequate bandwidth for digital switching up to ~10–20 MHz with minimal propagation delay. |
| VCE(sat) | ≤100 mV at IC = 5 mA, IB = 0.25 mA; guarantees low conduction loss and compatible logic-low output level for downstream CMOS/TTL inputs. |
Pinout & Package
SOT363-3 (SC-88 / TSSOP6) surface-mount plastic package: 2.2 mm × 1.35 mm footprint, 0.65 mm pitch, 0.95 mm max height, designed for reflow soldering on standard FR4 PCBs with tin-plated copper traces.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection of TR1; common reference node for first transistor's current path and bias network ground. |
| 2 | I1 | Base input of TR1; accepts logic-level voltage directly-no external resistor required due to integrated R1. |
| 3 | O2 | Collector output of TR2; active-high switching node delivering up to 100 mA to load referenced to GND2. |
| 4 | GND2 | Emiter connection of TR2; independent ground return for second transistor, enabling isolated dual-channel operation. |
| 5 | I2 | Base input of TR2; electrically identical to I1-supports independent control of second transistor with same bias architecture. |
| 6 | O1 | Collector output of TR1; complements O2 for dual-signal routing; shares same voltage/current specs and saturation performance. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET topology | Two fully independent NPN transistors with matched R1/R2 networks in one 6-pin SOT363-3 package-reduces board area by >40% vs. discrete dual-transistor + 4-resistor solution. |
| Integrated bias resistors | R1 = 2.2 kΩ and R2 = 47 kΩ per channel eliminate external base resistors, cutting BOM count by 4 parts and reducing pick-and-place cycle time. |
| Low VCE(sat) | ≤100 mV ensures <0.5 mW conduction loss at 5 mA, preserving noise margin and enabling direct interface with 1.8 V/3.3 V logic families. |
| Thermal robustness | Rth(j-a) = 417 K/W (per device) on FR4 allows sustained 100 mA operation up to 70 °C ambient without derating-validated per JEDEC JESD51-2. |
| Logic-compatible VI(on)/VI(off) | VI(on) = 0.75 V (typ) and VI(off) = 0.6 V (typ) provide clean TTL/CMOS threshold recognition without hysteresis or external level-shifting. |
Applications
| LED Indicator Driver | Microcontroller GPIO Expander |
|---|---|
|
Use Scenario: Driving multiple status LEDs from MCU pins with limited sink/source capability. IC Role / Device Role / Timing Role: Dual-channel low-side switch translating 3.3 V GPIO outputs into 20 mA LED currents. Use Value: Eliminates need for 4 discrete transistors + 4 base resistors; reduces layout area by 60% and improves assembly yield. |
Use Scenario: Extending limited GPIO count on Cortex-M0+ microcontrollers for sensor enable lines and reset controls. IC Role / Device Role / Timing Role: Logic-level translator and buffer isolating MCU pins from higher-current peripheral loads. Use Value: VI(on) ≤ 0.75 V ensures reliable turn-on from weak-drive GPIOs; VCE(sat) ≤ 100 mV maintains full 3.3 V high-level margin. |
| Level-Shifting Interface | Small-Signal Relay Driver |
|
Use Scenario: Bidirectional voltage translation between 5 V legacy peripherals and 3.3 V SoC subsystems. IC Role / Device Role / Timing Role: Active pull-down stage converting 5 V logic-high to 3.3 V-compatible low state via saturated switching. Use Value: R2/R1 = 21 ratio provides sharp turn-off edge and prevents partial conduction during voltage transitions. |
Use Scenario: Driving 5 V/10 mA coil relays in industrial I/O modules where space and component count are constrained. IC Role / Device Role / Timing Role: Low-saturation switch interfacing microcontroller outputs to relay coil return paths. Use Value: 100 mA rating exceeds typical relay hold current (7–15 mA); 50 V VCEO accommodates flyback voltage spikes without snubber. |
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 |
|---|---|---|---|
| PUMD10 | Complementary NPN/PNP pair instead of NPN/NPN; shares same R1/R2 values and SOT363-3 package. | Required when one channel needs high-side (source) switching and the other low-side (sink) switching in the same design. | Select PUMD10 only if mixed polarity drive is needed-PUMH10Z is optimal for dual low-side or parallel logic buffering. |
| PUMB10 | PNP/PNP configuration; identical bias resistor values and thermal specs but inverted polarity and opposite current flow direction. | Used where active-high enable signals must drive PNP-based load switches or high-side power rails. | Choose PUMB10 for high-side sourcing applications; PUMH10Z remains preferred for standard low-side digital interface tasks. |
Compared with PUMD10 and PUMB10, the PUMH10Z offers native dual low-side drive with consistent input/output polarity-reducing schematic complexity and eliminating cross-polarity layout errors in GPIO-expansion and LED-matrix designs.

FAQ
What is the maximum operating temperature for continuous 100 mA operation per channel?
The PUMH10Z supports continuous 100 mA per transistor up to 70 °C ambient temperature when mounted on a standard FR4 PCB with single-sided 35 µm copper, based on its 300 mW total power dissipation rating and 417 K/W junction-to-ambient thermal resistance. Above 70 °C, current must be linearly derated per the published power derating curve.
Can PUMH10Z be used to drive a 5 V, 20 mA LED directly from a 3.3 V GPIO?
Yes-the PUMH10Z's VI(on) of 0.75 V (typ) ensures reliable turn-on from a 3.3 V GPIO, and its 100 mA rating comfortably exceeds 20 mA LED current. With VCE(sat) ≤ 100 mV, the LED sees nearly full 5 V supply voltage across its anode-cathode path when used in low-side configuration.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 21 (typ) establishes internal feedback that stabilizes the transistor in deep saturation while ensuring rapid turn-off by pulling the base toward emitter potential. This ratio minimizes storage time and prevents latch-up in high-frequency digital switching, unlike un-biased or poorly biased discrete transistors.
Is PUMH10Z pin-compatible with older PUMH10 revisions?
Yes-the PUMH10Z uses the same SOT363-3 (TSSOP6) package and identical pinout as prior PUMH10 versions; the "Z" suffix denotes updated marking and compliance with latest Nexperia quality and environmental standards, with no functional or mechanical changes affecting PCB layout or circuit integration.
