Product details
Overview
PUMH9/ZLX from Nexperia is an NPN/NPN resistor-equipped double transistor (RET) in SOT363-3 (SC-88) package, rated for 50 V VCEO, 100 mA output current per transistor, with integrated R1 = 10 kΩ and R2 = 47 kΩ bias resistors. It functions as a dual digital switching element for level translation and IC input control in space-constrained automotive and industrial PCBs.
For engineers reviewing the PUMH9/ZLX datasheet, PUMH9/ZLX pinout, PUMH9/ZLX application, or PUMH9/ZLX equivalent, this device serves as a drop-in replacement for discrete base-resistor transistor pairs-reducing BOM count, simplifying layout, and lowering assembly cost in low-voltage digital interface circuits.
Technical Context
The PUMH9/ZLX integrates two matched NPN transistors with monolithically embedded bias networks: R1 (input resistor) and R2 (base-emitter feedback resistor), forming a self-biased switch topology per channel. Each transistor operates independently with open-base VCEO = 50 V and IO = 100 mA rating.
Its R2/R1 ratio of 4.7 enables stable saturation under varying temperature (−40 °C to +150 °C ambient), while built-in 2.5 pF collector capacitance and 230 MHz fT support reliable switching up to ~10 MHz in digital logic interfacing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage before breakdown; defines rail compatibility with 3.3 V/5 V/12 V digital systems |
| IO | 100 mA - Continuous DC output current per transistor; sufficient for driving LEDs, small relays, or logic inputs |
| R1 | 10 kΩ ±30% - Input bias resistor; sets base current for predictable turn-on at standard logic-high voltages (e.g., 3.3 V) |
| R2/R1 | 4.7 - Feedback resistor ratio; ensures deep saturation (VCE(sat) ≤ 100 mV @ IC = 5 mA) across temperature |
| fT | 230 MHz - Transition frequency; supports fast edge rates in digital switching without oscillation risk |
| VCE(sat) | ≤100 mV @ IC = 5 mA, IB = 0.25 mA - Low saturation voltage minimizes power loss and heat generation in active-switching mode |
| Cc | 2.5 pF - Collector capacitance at 10 V; limits high-frequency signal coupling and ensures clean digital transitions |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mounted package: 2.2 mm × 1.35 mm footprint, 0.65 mm pitch, 0.95 mm max height, designed for reflow soldering on FR4 PCBs with standard 0.5 mm pad width.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1; common reference node for first transistor's current path |
| 2 | I1 | Base input for TR1; accepts logic-level signals through internal R1 resistor |
| 3 | O2 | Collector output for TR2; active-low switching node referenced to GND2 |
| 4 | GND2 | Emiter connection for TR2; independent ground return for second transistor |
| 5 | I2 | Base input for TR2; isolated logic input with dedicated R1–R2 network |
| 6 | O1 | Collector output for TR1; primary switching output referenced to GND1 |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET architecture | Two independent, resistor-equipped transistors in one SOT363-3 package-eliminates need for four external resistors in discrete implementations |
| Thermal robustness | Rth(j-a) = 417 K/W (per device); enables 300 mW total dissipation at Tamb ≤ 25 °C on standard FR4 PCB |
| Wide operating temperature range | −55 °C to +150 °C ambient; qualified for under-hood automotive and industrial control environments |
| Low VI(on)/VI(off) hysteresis | VI(on) = 0.8–1.4 V, VI(off) = 0.5–0.7 V at 25 °C; ensures noise-immune logic-level recognition with TTL/CMOS compatibility |
| ESD tolerance | HBM > 2 kV (per JESD22-A114); protects against handling damage during SMT assembly and board handling |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input Stage |
|---|---|
Use Scenario: Level-shifting and isolation of 12 V sensor signals into 3.3 V microcontroller GPIOs in door module ECUs. IC Role / Device Role / Timing Role: Dual-channel digital switch providing galvanic separation and voltage translation between higher-voltage sensors and low-voltage logic. Use Value: Reduces component count by replacing two BC847 + four resistors per channel; improves layout density and long-term reliability in vibration-prone environments. |
Use Scenario: Interfacing 24 V field actuators to FPGA-based control logic in modular I/O cards. IC Role / Device Role / Timing Role: Input conditioning element converting industrial-standard 24 V ON/OFF signals into clean 0 V/3.3 V logic levels for FPGA input banks. Use Value: Enables direct connection without external pull-ups or level shifters; R2/R1 ratio ensures consistent turn-on even with aging or temperature drift in factory-floor conditions. |
| Consumer Appliance Power Sequencing | Medical Diagnostic Equipment Interface |
Use Scenario: Controlling sequential enable lines for multiple DC-DC converters in smart HVAC control boards. IC Role / Device Role / Timing Role: Dual low-side switch managing power-up sequencing of subsystem rails (e.g., analog front-end before digital core). Use Value: Provides precise timing margin via matched transistor characteristics and integrated biasing-no timing skew between channels due to resistor matching. |
Use Scenario: Isolating patient-connected sensor outputs from main processing unit in portable ECG monitors. IC Role / Device Role / Timing Role: Signal gating element enabling/disabling analog sensor paths during calibration or standby modes. Use Value: Low VCE(sat) (<100 mV) preserves signal integrity in µV-level analog paths; SOT363-3 footprint allows placement near sensitive analog traces with minimal parasitic inductance. |
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 |
|---|---|---|---|
| BC847BPDW1T3G | Discrete dual NPN pair (no built-in resistors); requires external R1/R2 network per transistor | Higher BOM count and layout area; less suitable for ultra-dense designs | Select when fine-tuned biasing or adjustable gain is required beyond fixed RET ratios |
| PUMD9 | NPN/PNP complement; same package and bias values but mixed polarity configuration | Enables push-pull or complementary switching topologies not possible with NPN/NPN-only PUMH9 | Select for bidirectional signal control or level inversion where both sourcing and sinking capability is needed |
Compared with BC847BPDW1T3G, PUMH9/ZLX reduces design effort and assembly cost by integrating biasing; compared with PUMD9, it provides identical switching polarity for parallel load control-critical in synchronized digital enable applications.

FAQ
What is the maximum continuous current per transistor in PUMH9/ZLX?
The PUMH9/ZLX supports 100 mA DC output current per transistor under Tamb ≤ 25 °C with proper PCB thermal relief. Derating applies above 25 °C: at 75 °C ambient, maximum usable current drops to ~60 mA per transistor based on its 417 K/W junction-to-ambient thermal resistance and 300 mW total device power limit.
Can PUMH9/ZLX be used in place of BC847 series transistors?
Yes-PUMH9/ZLX serves as a functional drop-in alternative to BC847-based dual-transistor circuits in digital switching applications. Its integrated 10 kΩ/47 kΩ resistor network replicates typical BC847 biasing, eliminating four external resistors and reducing layout area by >40% in SOT363-3 footprint.
Is PUMH9/ZLX automotive-qualified?
No-PUMH9/ZLX is not AEC-Q101 qualified. While it operates across −55 °C to +150 °C and is widely used in automotive body electronics, Nexperia explicitly states in its legal disclaimers that non-automotive-qualified products like PUMH9/ZLX are not warranted for safety-critical or life-support systems.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 = 4.7 ratio ensures strong base drive relative to leakage, forcing deep saturation (VCE(sat) ≤ 100 mV) even at elevated temperatures. This prevents partial turn-on states that could cause excessive heating or logic ambiguity-particularly critical in noisy industrial environments where marginal base currents may occur.
