Product details
Overview
PUMH18 from Nexperia is an AEC-Q101-qualified 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 bias resistors R1 = 4.7 kΩ and R2 = 10 kΩ. It serves as a compact, dual-channel digital switching element for low-current peripheral interfacing in automotive and industrial control systems.
For engineers reviewing the PUMH18 datasheet, PUMH18 pinout, PUMH18 application, or PUMH18 equivalent, this device is selected for space-constrained PCBs requiring reduced external component count, simplified base-drive logic, and automotive-grade reliability without discrete bias networks.
Technical Context
The PUMH18 integrates two matched NPN transistors with monolithically embedded base bias resistors-R1 (input resistor) and R2 (feedback resistor)-enabling direct TTL/CMOS-level input drive without external pull-up or current-limiting resistors. Each transistor operates independently with open-base VCEO = 50 V and IO = 100 mA rating.
Its internal resistor ratio R2/R1 = 2.1 typ ensures stable saturation under varying temperature (−40 °C to +150 °C junction), while built-in ESD protection and FR4-optimized thermal resistance (Rth(j-a) = 417 K/W per device) support robust operation in reflow-soldered automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage with base open; defines rail compatibility up to 48 V automotive systems. |
| IO | 100 mA - Continuous DC output current per transistor; supports driving LEDs, small relays, or logic inputs directly. |
| R1 | 4.7 kΩ ±28% - Input bias resistor enabling ~1 mA base current at 5 V logic high; sets minimum drive strength. |
| R2/R1 | 2.1 typ - Feedback-to-input resistor ratio ensuring reliable saturation and noise immunity across temperature. |
| hFE | 50 min - DC current gain at VCE = 5 V, IC = 10 mA; guarantees ≥20× overdrive margin for guaranteed switching. |
| VCE(sat) | 100 mV max - Low saturation voltage at IC = 10 mA, IB = 0.5 mA; minimizes power loss in active switching. |
| fT | 230 MHz typ - Transition frequency at VCE = 5 V, IC = 10 mA; supports fast digital edge rates up to ~30 MHz. |
Pinout & Package
SOT363-3 (SC-88/TSSOP6) plastic surface-mounted package: 1.35 mm × 2.2 mm footprint, 0.65 mm pitch, 0.95 mm max height; optimized for automated placement and reflow soldering on FR4 PCBs with single-sided 35 µm copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1; common reference for first transistor's current path. |
| 2 | I1 | Base input for TR1; accepts logic-level signals (VI(on) = 1.5–2.5 V) with internal R1 limiting base current. |
| 3 | O2 | Collector output for TR2; active-high sink output referenced to GND2. |
| 4 | GND2 | Emiter connection for TR2; independent ground node allowing dual isolated switching paths. |
| 5 | I2 | Base input for TR2; electrically identical to I1 but isolated; enables independent control of second channel. |
| 6 | O1 | Collector output for TR1; active-high sink output referenced to GND1. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET architecture | Two fully independent, resistor-equipped NPN transistors in one ultra-small SOT363-3 package-eliminates need for four external bias resistors. |
| AEC-Q101 qualification | Qualified for automotive applications per stress test standard; validated for −40 °C to +125 °C ambient operation with 150 °C max junction temperature. |
| Logic-compatible input threshold | VI(on) = 1.5–2.5 V and VI(off) = 0.3–0.9 V enable direct interface with 3.3 V and 5 V CMOS/TTL outputs without level-shifting. |
| Thermal derating support | Per-device Ptot = 300 mW at Tamb ≤ 25 °C, with linear derating to zero at 125 °C-supports sustained operation in enclosed automotive ECUs. |
| Low-output capacitance | Cc = 2.5 pF max enables fast turn-off (toff < 10 ns typical) and minimal signal distortion in high-speed digital buffering. |
Applications
| Automotive Door Module Driver | Industrial PLC Input Isolation |
|---|---|

Use Scenario: Level-shifting and galvanic isolation between 24 V field sensors and 3.3 V microcontroller GPIOs in programmable logic controllers. IC Role / Device Role / Timing Role: Digital input buffer with built-in current limiting and noise rejection via R2 feedback network. Use Value: Eliminates external pull-down and series resistors while maintaining VI(off) < 0.9 V for reliable logic-low detection under EMI. |
| USB-C Port Power Switch Control | IoT Sensor Node GPIO Expander |
|
Use Scenario: Enabling/disabling VBUS power paths and CC line terminations in USB-C receptacle circuits with tight layout constraints. IC Role / Device Role / Timing Role: Dual NPN switch controlling gate drive for load switches and termination resistors with precise on/off timing. Use Value: Achieves ton/toff < 20 ns due to low Cc and high fT, meeting USB-C specification timing margins for hot-plug detection. |
Use Scenario: Expanding MCU GPIO count to drive multiple environmental sensor enable lines (e.g., I²C peripherals, ADC references) in battery-powered edge nodes. IC Role / Device Role / Timing Role: Low-quiescent-current digital switch enabling sensors only during measurement cycles to minimize system sleep current. Use Value: Delivers <100 nA ICEO leakage at 150 °C, ensuring <1 µA total off-state current across all enabled channels in deep-sleep mode. |
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 |
|---|---|---|---|
| PUMD18 | Complementary NPN/PNP pair; same package, R1/R2 values, and ratings-but mixed polarity limits use to push-pull or level-shift topologies. | Required where bidirectional signal control or complementary switching (e.g., half-bridge pre-driver) is needed instead of dual-sink operation. | Select when circuit requires one NPN sink + one PNP source per channel rather than two independent sinks. |
| PUMB18 | PNP/PNP configuration; identical package and resistor values but inverted polarity-requires high-side switching topology and inverted logic drive. | Suitable for high-side load switching (e.g., 12 V sensor supply enable) where ground-referenced control is impractical. | Choose for applications needing two independent high-side switches with logic-compatible input thresholds. |
Compared with PUMD18 and PUMB18, the PUMH18 uniquely provides two matched NPN sink outputs with shared ground flexibility, making it optimal for low-side digital interfacing where polarity consistency, PCB routing simplicity, and minimized component count are prioritized.

FAQ
Is PUMH18 pin-compatible with other SOT363-3 RETs like PUMD18?
Yes-PUMH18 shares identical SOT363-3 (TSSOP6) mechanical dimensions and pinout numbering with PUMD18 and PUMB18. However, internal transistor polarity differs: PUMH18 is NPN/NPN, PUMD18 is NPN/PNP, and PUMB18 is PNP/PNP. Physical replacement is possible, but electrical functionality requires circuit verification.
What is the maximum operating temperature for continuous use?
The PUMH18 supports continuous operation up to 150 °C junction temperature (Tj) and −65 °C to +150 °C ambient (Tamb). At 125 °C ambient, its per-device power dissipation must be derated to ≤120 mW based on the published 417 K/W thermal resistance curve.
Can PUMH18 drive a 5 V relay coil directly?
Yes-each channel delivers 100 mA IO at VCE ≤ 100 mV saturation, sufficient for most 5 V/70 mA signal relays. Ensure coil flyback diode is placed externally across the relay terminals, as the device lacks integrated clamp diodes.
Does PUMH18 require external decoupling capacitors?
No dedicated decoupling is required for basic switching operation. However, for high-frequency (>1 MHz) or noise-sensitive applications, a 100 nF ceramic capacitor between each GND pin (1 and 4) and local system ground is recommended to suppress transient coupling between channels.
