Product details
Overview
PEMH9 from Nexperia is an NPN/NPN resistor-equipped double transistor (RET) in SOT666 package, rated for 50 V VCEO, 100 mA output current per transistor, with built-in bias resistors R1 = 10 kΩ and R2 = 47 kΩ. It functions as a dual digital switching element for low-current logic interfacing and peripheral control in space-constrained PCBs.
For engineers reviewing the PEMH9 datasheet, PEMH9 pinout, PEMH9 application, or PEMH9 equivalent, this device is selected for compact dual-transistor logic-level translation, IC input driving, and replacement of discrete BJT pairs where board area and assembly cost are critical.
Technical Context
The PEMH9 integrates two identical NPN transistors, each with monolithically embedded base bias resistors (R1 to base, R2 from base to emitter), enabling direct TTL/CMOS-compatible input drive without external components. Its dual configuration supports independent or cascaded switching paths.
Designed for digital signal conditioning, it operates within −55 °C to +150 °C ambient range, delivers 100 mA continuous output per channel, and maintains stable hFE ≥ 100 at IC = 5 mA, VCE = 5 V, Tamb = 25 °C - confirming suitability for reliable low-power logic interface duty.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; defines safe operating voltage headroom for 3.3 V/5 V logic systems. |
| IO | 100 mA - Continuous output current per transistor; supports driving LEDs, small relays, or logic inputs without external current boosting. |
| R1 | 10 kΩ (7–13 kΩ) - Input bias resistor value; sets base current for predictable turn-on with standard logic high levels (≥1.4 V). |
| R2/R1 ratio | 4.7 (3.7–5.7) - Ensures stable saturation and noise immunity by fixing feedback-to-input resistance ratio. |
| hFE | ≥100 - DC current gain at 5 mA collector current; guarantees sufficient drive margin for saturated switching in digital applications. |
| VCE(sat) | ≤100 mV - Low saturation voltage at IC = 5 mA, IB = 0.25 mA; minimizes power loss and heat generation during on-state operation. |
| fT | 230 MHz - Transition frequency; confirms adequate bandwidth for fast digital edge handling up to ~10–20 MHz toggle rates. |
Pinout & Package
SOT666 plastic surface-mount package: 6-pin, 0.5 mm pitch, 1.6 mm × 1.2 mm × 0.55 mm body height; ultra-small footprint optimized for high-density routing and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1; common reference node for first transistor's current path. |
| 2 | I1 | Input (base) for TR1; accepts logic-level signals directly without series resistor. |
| 3 | O2 | Collector output for TR2; active-high sink/source node when TR2 is switched. |
| 4 | GND2 | Emiter connection for TR2; isolated ground return for second transistor. |
| 5 | I2 | Input (base) for TR2; independently controllable logic input with internal R1/R2 bias network. |
| 6 | O1 | Collector output for TR1; primary switching node for first transistor, electrically separate from O2. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET topology | Two matched, resistor-equipped NPN transistors in single die; eliminates layout mismatch and reduces interconnect parasitics between paired BJTs. |
| Built-in R1/R2 bias network | R1 = 10 kΩ, R2 = 47 kΩ per transistor; enables direct connection to 3.3 V/5 V logic outputs while ensuring robust saturation and noise rejection. |
| Ultra-compact SOT666 package | 1.6 mm × 1.2 mm footprint; saves >60% board area versus two discrete SOT23 transistors plus four bias resistors. |
| 100 mA per-channel rating | Rated continuous output current supports LED drivers, buffer stages, and microcontroller GPIO expanders without derating at 25 °C. |
Applications
| LED Indicator Driver | Microcontroller GPIO Expander |
|---|---|
Use Scenario: Driving multiple status LEDs from limited MCU I/O pins with minimal external components. IC Role / Device Role / Timing Role: Dual low-side switch providing independent current-sinking paths for red/green dual-color indicators or multi-segment displays. Use Value: Eliminates need for eight discrete resistors and two transistors; reduces BOM count by 6 parts and PCB area by 2.5 mm² per channel pair. | Use Scenario: Extending digital output capability of resource-constrained MCUs (e.g., ARM Cortex-M0+, PIC16F) for sensor enable lines or peripheral reset control. IC Role / Device Role / Timing Role: Level-shifting and current-boosting buffer for open-drain or weak-drive GPIOs, supporting 5 V tolerant loads from 3.3 V cores. Use Value: Enables direct 3.3 V logic control of 5 V peripherals with guaranteed VCE(sat) ≤ 100 mV, minimizing voltage drop and timing skew. |
| Logic-Level Translator | Low-Power Sensor Interface |
Use Scenario: Bidirectional level shifting between 1.8 V FPGA I/O banks and 3.3 V sensor subsystems using push-pull configurations. IC Role / Device Role / Timing Role: Active pull-up/pull-down switch implementing voltage-domain bridging without direction control pins or external biasing. Use Value: Achieves <10 ns propagation delay with R1/R2-defined hysteresis, supporting 10 MHz data rates while consuming <5 µA quiescent current per channel. | Use Scenario: Enabling/disabling analog sensors (e.g., temperature, humidity) via microcontroller-controlled power gating to reduce system standby current. IC Role / Device Role / Timing Role: Low-leakage (ICEO ≤ 5 µA at 150 °C) high-side or low-side load switch managing sensor VDD rail. Use Value: Cuts sensor supply leakage by >99% vs. passive resistive pull-down; supports industrial-grade thermal operation up to 150 °C junction temperature. |
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 |
|---|---|---|---|
| PEMB9 | PNP/PNP complement; same SOT666 package, identical R1/R2 values, but inverted polarity. | Required for high-side switching or complementary logic where sourcing current is needed instead of sinking. | Select PEMB9 only when circuit topology demands PNP-based active-high output or rail-to-rail inversion. |
| PEMD9 | NPN/PNP configuration; shares SOT666 footprint and bias resistor values, but channels differ in polarity. | Suitable for push-pull driver stages or differential input buffering requiring matched turn-on/off characteristics across polarities. | Choose PEMD9 when building complementary output stages or interfacing with differential receivers needing matched threshold behavior. |
Compared with PEMB9 and PEMD9, the PEMH9 provides matched NPN/NPN switching symmetry ideal for parallel load driving or duplicated logic paths - whereas PEMB9 suits high-side control and PEMD9 enables true push-pull operation, making selection dependent on required current direction and output logic polarity.

FAQ
What is the maximum operating temperature for PEMH9?
The PEMH9 has a specified junction temperature limit of 150 °C and an ambient operating range of −55 °C to +150 °C. Its thermal resistance is 417 K/W (per device on FR4 PCB), allowing sustained operation at full 100 mA load up to +85 °C ambient with proper layout - verified per IEC 60134 limiting values.
Can PEMH9 be used in automotive applications?
No - the PEMH9 is explicitly marked as non-automotive qualified in its revision history and legal disclaimers. It lacks AEC-Q101 qualification, automotive-grade screening, and extended reliability testing. For automotive use, Nexperia offers qualified alternatives such as the PUMH9 family, which undergoes full automotive qualification.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 4.7 ensures stable base bias feedback that prevents thermal runaway and improves noise immunity. With R1 = 10 kΩ and R2 = 47 kΩ, the effective base current is regulated to maintain VBE ≈ 0.7 V under typical drive conditions, guaranteeing consistent saturation across process and temperature variations.
Is there crosstalk between the two transistors in PEMH9?
No measurable functional crosstalk exists - the transistors share only substrate and thermal coupling, not electrical nodes. Electrical isolation between channels is confirmed by independent pinning (separate GND1/GND2, O1/O2, I1/I2) and characterization showing no signal coupling in switching transient tests per Nexperia's application notes and SPICE models.
