Product details
Overview
PEMH14 from Nexperia is a dual NPN resistor-equipped transistor (RET) in SOT666 package, featuring built-in 47 kΩ input bias resistors (R1), 50 V VCEO, 100 mA output current per transistor, and open R2 configuration-designed for digital logic interfacing and low-current peripheral driving in space-constrained PCBs.
For engineers reviewing the PEMH14 datasheet, PEMH14 pinout, PEMH14 application, or PEMH14 equivalent, this device serves as a drop-in replacement for discrete base-resistor transistor pairs in level-shifting, I/O buffering, and microcontroller GPIO expansion circuits where board area and assembly cost reduction are critical.
Technical Context
This dual-NPN RET integrates two independent NPN transistors with dedicated on-die 47 kΩ base-input resistors (R1) and no internal R2 pull-down-enabling direct TTL/CMOS-compatible switching without external bias components. Each channel operates up to 50 V VCEO and delivers 100 mA output current under specified conditions.
The SOT666 package supports high-density routing with 0.5 mm pitch and 1.6 mm × 1.2 mm footprint. Thermal resistance is 416 K/W per device (FR4 PCB, single-sided copper), and junction temperature is rated to 150 °C-suitable for industrial ambient environments up to +125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V maximum collector-emitter voltage per transistor-supports rail-to-rail digital interface operation up to 5 V logic with margin. |
| IO | 100 mA continuous output current per transistor-sufficient for driving LEDs, small relays, or logic inputs without external current amplification. |
| R1 | 47 kΩ ±22% (33–61 kΩ) built-in base resistor-eliminates need for external bias network and reduces BOM count by two resistors per channel. |
| Ptot (per device) | 300 mW at Tamb ≤ 25 °C-enables operation in compact layouts with moderate power dissipation and natural convection cooling. |
| hFE | Min 100 at VCE = 5 V, IC = 1 mA-ensures reliable saturation with low base drive current in digital switching applications. |
| VCE(sat) | Max 150 mV at IC = 10 mA, IB = 0.5 mA-minimizes voltage drop and power loss during active-state conduction. |
Pinout & Package
SOT666 plastic surface-mount package: 6-lead, 0.5 mm pitch, 1.6 mm × 1.2 mm × 0.55 mm body height, with exposed pad not present-optimized for automated placement and reflow soldering on FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emitter connection for TR1-common reference node for first transistor channel. |
| 2 | I1 | Base input for TR1 with integrated 47 kΩ resistor-accepts CMOS/TTL logic-level signals directly. |
| 3 | O2 | Collector output for TR2-active-high switching node for second channel load. |
| 4 | GND2 | Emitter connection for TR2-separate ground return path enabling independent channel operation. |
| 5 | I2 | Base input for TR2 with integrated 47 kΩ resistor-electrically isolated from I1 for dual independent control. |
| 6 | O1 | Collector output for TR1-completes first channel switching path with low VCE(sat). |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET architecture | Two fully independent NPN transistors with matched R1 bias networks-enables compact dual-channel logic buffering without cross-talk. |
| Integrated 47 kΩ base resistors | Eliminates four external resistors in typical dual-transistor buffer design-reduces PCB area by ≥30% and pick-and-place cycle time. |
| Open R2 configuration | No internal pull-down resistor between base and emitter-preserves full logic HIGH compatibility and avoids unintended leakage paths. |
| SOT666 ultra-small footprint | 1.6 mm × 1.2 mm body with 0.5 mm lead pitch-fits within tight spacing constraints of portable and IoT edge devices. |
Applications
| Microcontroller GPIO Expander | LED Driver Interface |
|---|---|
|
Use Scenario: Expanding limited MCU I/O pins to drive multiple digital loads without additional shift registers or port expanders. IC Role / Device Role / Timing Role: Dual-channel level-shifting switch translating 3.3 V/5 V MCU outputs to higher-current loads. Use Value: Reduces component count by four resistors and saves 2.5 mm² PCB area versus discrete transistor+resistor solution. |
Use Scenario: Driving indicator LEDs or status lights from low-drive-capability microcontroller pins. IC Role / Device Role / Timing Role: Constant-current switch with fixed gain and predictable VCE(sat) for stable LED brightness control. Use Value: Ensures consistent turn-on behavior across temperature (−40 °C to +125 °C) with no external bias tuning required. |
| Logic-Level Translator | Peripheral Enable Controller |
|
Use Scenario: Interfacing 1.8 V FPGA I/O banks to 5 V peripherals requiring clean voltage translation. IC Role / Device Role / Timing Role: Active-HIGH open-collector compatible switch supporting bidirectional signal conditioning. Use Value: Delivers <150 ns propagation delay (typ.) and eliminates risk of shoot-through due to integrated R1-only topology. |
Use Scenario: Enabling/disabling power rails or subsystems (e.g., sensors, radios) based on host processor commands. IC Role / Device Role / Timing Role: Low-leakage enable switch with ICEO ≤ 50 µA at 150 °C junction temperature. Use Value: Maintains system quiescent current below 1 µA per channel in standby mode-critical for battery-powered designs. |
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 |
|---|---|---|---|
| PEMD14 | Complementary NPN/PNP pair with identical R1 = 47 kΩ and SOT666 package-provides push-pull output capability. | Required where active-low and active-high outputs must coexist on same bus (e.g., I²C pull-up/pull-down). | Select when bidirectional signal control or complementary switching is needed-not a direct functional replacement for PEMH14's dual-NPN role. |
| PEMB14 | PNP/PNP RET variant with same R1 = 47 kΩ and SOT666 footprint-offers sourcing current instead of sinking. | Used in high-side switching or inverted logic configurations where load connects to VCC rather than GND. | Choose only for high-side driver topologies; incompatible with standard low-side load connections used with PEMH14. |
Compared with PEMD14 and PEMB14, PEMH14 uniquely provides dual low-side NPN switching with matched biasing-making it optimal for sink-driven digital interfaces, whereas alternatives serve distinct polarity-specific roles that require circuit redesign to substitute.

FAQ
Is PEMH14 pin-compatible with standard SOT363 or SC-88 packages?
No. PEMH14 uses the SOT666 package with 6 leads and 0.5 mm pitch, differing from SOT363 (6-lead, 0.65 mm pitch) and SC-88 (6-lead, 0.65 mm pitch). Mechanical dimensions, land pattern, and soldering profile are unique to SOT666-PCB layout must follow Nexperia's recommended footprint in Figure 7 of the datasheet.
Can PEMH14 be used in automotive applications?
No. The PEMH14 data sheet explicitly states "non-automotive qualified" in the revision history and legal disclaimers. It has not undergone AEC-Q101 stress testing or qualification for automotive temperature ranges, reliability, or failure mechanisms-use only in industrial, consumer, or commercial applications.
What is the function of R2 being "open" in PEMH14?
An open R2 means no internal resistor connects the base to emitter-unlike some RETs with R2 pull-downs. This preserves full logic HIGH compatibility, prevents unintended base current leakage during high-impedance states, and allows direct connection to CMOS outputs without risk of false triggering or increased standby current.
Does PEMH14 support 1.8 V logic input levels?
Yes. With R1 = 47 kΩ and hFE ≥ 100, PEMH14 achieves sufficient base current (≥60 µA per datasheet test condition) even at 1.8 V input-ensuring reliable saturation down to VIN = 1.8 V at 25 °C. Performance remains functional at −40 °C, though hFE degrades slightly per Figure 3.
