Product details
Overview
PUMH11/ZLX from Nexperia is a dual NPN resistor-equipped transistor (RET) in SOT363 (SC-88) surface-mount package, configured as two independent NPN transistors with integrated 10 kΩ input bias resistors (R1) and matched R2/R1 ratio of 1.0. It delivers 100 mA per transistor output current, supports 50 V collector-emitter voltage, and is AEC-Q101 qualified for automotive signal conditioning and digital interface applications.
For engineers reviewing the PUMH11/ZLX datasheet, PUMH11/ZLX pinout, PUMH11/ZLX application, or PUMH11/ZLX equivalent, this device serves as a space- and BOM-optimized replacement for discrete NPN pairs in level-shifting, GPIO buffering, and low-power logic interfacing where built-in biasing eliminates external resistors and reduces PCB footprint.
Technical Context
The PUMH11/ZLX integrates two identical NPN transistors, each with monolithically embedded R1 = 10 kΩ base-input resistors and R2 = 10 kΩ emitter-feedback resistors, enabling direct TTL/CMOS logic-level drive without external bias components. Its matched R2/R1 ratio (0.8–1.2) ensures consistent saturation behavior across temperature.
It operates with VI(on) = 1.8–2.5 V and VI(off) = 0.8–1.1 V at IC = 10 mA and VCE = 0.3 V or 5 V respectively, supporting reliable switching in 3.3 V and 5 V digital systems. Thermal resistance is 417 K/W per device on FR4 PCB, enabling stable operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V industrial control interfaces. |
| IO | 100 mA - Continuous DC output current per transistor; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 10 kΩ (7–13 kΩ) - Integrated base-input resistor; eliminates need for external pull-up/pull-down, reducing component count by ≥2 per channel. |
| R2/R1 | 1.0 (0.8–1.2) - Tight tolerance on internal feedback resistor ratio; ensures predictable turn-on/off thresholds across production lots. |
| hFE | ≥30 at IC = 5 mA, VCE = 5 V - Minimum DC current gain; guarantees robust saturation with low base drive current (≤0.5 mA). |
| VCE(sat) | ≤150 mV at IC = 10 mA, IB = 0.5 mA - Low saturation voltage; minimizes power loss and self-heating in high-duty-cycle switching. |
| fT | 230 MHz - Transition frequency of internal transistor; supports clean edge response in <10 MHz digital signal routing. |
Pinout & Package
SOT363 (SC-88) 6-pin ultra-small flat lead package, 2.2 mm × 1.35 mm × 0.95 mm body, 0.65 mm pitch, designed for reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND (emitter of TR1) | Common emitter reference for first transistor; connects to system ground or local return path. |
| 2 | Input (base of TR1) | Logic-level input node for TR1; internally biased via R1 = 10 kΩ to VIN. |
| 3 | Output (collector of TR2) | Active-low output node for second transistor; sinks current when TR2 is on. |
| 4 | GND (emitter of TR2) | Common emitter reference for second transistor; electrically isolated from Pin 1 but same potential in typical layout. |
| 5 | Input (base of TR2) | Logic-level input node for TR2; independently biased via its own R1 resistor. |
| 6 | Output (collector of TR1) | Active-low output node for first transistor; provides complementary switching channel to Pin 3. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM ≥2 kV), enabling use in infotainment and body control modules. |
| Integrated dual NPN RET topology | Two fully independent NPN channels with matched R1/R2 networks in one SC-88 package - reduces board area by >40% vs. discrete transistor + resistor solutions. |
| 100 mA per channel output capability | Supports direct drive of optocoupler inputs, small-signal MOSFET gates, or microcontroller GPIO expanders without external amplification. |
| VI(on)/VI(off) window of 1.8–2.5 V / 0.8–1.1 V | Ensures clean logic-level compatibility with 3.3 V LVTTL and 5 V CMOS families while rejecting noise below 0.8 V. |
| Thermal resistance Rth(j-a) = 417 K/W (per device) | Enables continuous 100 mA operation at ambient ≤85 °C on standard FR4 PCB without heatsinking or airflow. |
Applications
| Automotive Body Control Unit (BCU) | Industrial PLC Digital Input Module |
|---|---|
Use Scenario: Level-shifting and isolation of 24 V sensor signals into 3.3 V microcontroller GPIOs. IC Role / Device Role / Timing Role: Dual-channel active-low signal conditioner with built-in biasing, replacing two discrete transistors and four resistors. Use Value: Reduces BOM count by 6 components per channel and improves long-term stability by eliminating resistor drift and solder joint variance. |
Use Scenario: Buffering and debouncing of mechanical switch inputs in DIN-rail mounted controllers. IC Role / Device Role / Timing Role: High-immunity digital input front-end with controlled VI(on)/VI(off) thresholds and fast turn-off (toff < 100 ns). Use Value: Eliminates need for external RC filters and Schmitt triggers, cutting input stage design time by ~3 days per I/O channel. |
| Consumer Appliance Control Board | Medical Diagnostic Device Interface |
Use Scenario: Driving LED status indicators and relay coils from low-power MCU outputs. IC Role / Device Role / Timing Role: Dual low-side switch with integrated base resistors, operating from 3.3 V supply with 100 mA per channel sink capability. Use Value: Enables single-chip control of up to 4 LEDs or 2 relays with no external passive components, saving 2.1 mm² PCB area per channel. |
Use Scenario: Isolating patient-connected analog sensor signals from digital processing circuitry. IC Role / Device Role / Timing Role: Galvanically isolated digital enable/disable gate for analog multiplexers and ADC drivers. Use Value: Provides creepage/clearance-compliant signal gating using only internal biasing - avoids risk of capacitor aging or resistor tolerance drift affecting safety margins. |
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 |
|---|---|---|---|
| NSVD2N1000MZT5G | Higher VCEO = 60 V, lower R1 = 4.7 kΩ, SOT-563 package (smaller, 5-pin, single-channel). | Requires two devices for dual-channel function; better suited for 48 V industrial bus monitoring. | Select when higher voltage margin or tighter R1 tolerance (±1%) is required, accepting doubled footprint and assembly cost. |
| EMX11T2R | Same SOT-363 package, but NPN/PNP complement pair; R1 = 22 kΩ, R2/R1 = 0.5. | Provides push-pull output capability instead of dual low-side switching; unsuitable for parallel channel buffering. | Choose only if complementary drive (e.g., half-bridge gate control) is needed - not a functional substitute for PUMH11/ZLX's dual-NPN topology. |
Compared with NSVD2N1000MZT5G and EMX11T2R, PUMH11/ZLX uniquely delivers matched dual-NPN channels with 10 kΩ biasing and 1.0 R2/R1 ratio in SC-88, making it optimal for space-constrained, cost-sensitive digital interface consolidation where channel symmetry and logic-level compatibility are critical.

FAQ
What is the maximum allowable ambient temperature for continuous 100 mA operation per channel?
At 100 mA per channel and Tamb ≤ 85 °C on standard FR4 PCB with single-sided copper, PUMH11/ZLX remains within its 150 °C max junction temperature limit due to its 417 K/W per-device thermal resistance. Derating begins above 85 °C ambient; full 100 mA is not sustainable at 125 °C ambient without forced cooling or enhanced copper pour.
Can PUMH11/ZLX be used as a level shifter between 1.8 V and 5 V logic domains?
No - its VI(on) minimum is 1.8 V and VI(off) maximum is 1.1 V, creating insufficient noise margin for reliable 1.8 V input recognition. It is validated for 3.3 V and 5 V CMOS/TTL inputs only. For 1.8 V systems, a dedicated level translator like NXSA1012GW is recommended.
Is wave soldering supported for PUMH11/ZLX in SOT363 package?
No - the datasheet explicitly states "reflow soldering is the only recommended soldering method." Wave soldering risks thermal damage to internal resistors and die attach, and the SOT363 footprint (Fig 14) is provided only for reference; no qualification data exists for wave process compatibility.
Does the R2/R1 ratio tolerance affect switching speed consistency between the two channels?
Yes - the 0.8–1.2 R2/R1 tolerance directly impacts base current distribution and thus ton/toff matching. At extremes, channel-to-channel propagation delay variation can reach ±15 ns under identical load conditions. For timing-critical dual-edge applications, post-layout simulation with worst-case resistor corners is advised.
