Product details
Overview
PEMH19 from Nexperia is a dual NPN resistor-equipped transistor (RET) in SOT666 package, integrating two independent NPN transistors each with a 22 kΩ input bias resistor (R1) and open R2. It supports 50 V VCEO, 100 mA output current per transistor, and operates across −65 °C to +150 °C ambient. Used for low-current digital logic interfacing and IC input control in space-constrained consumer and industrial PCBs.
For engineers reviewing the PEMH19 datasheet, PEMH19 pinout, PEMH19 application, or PEMH19 equivalent, this page delivers verified electrical specs, validated dual-transistor pin mapping, thermal derating curves, real-world driver use cases, and direct alternatives with documented R1/R2 and gain differences - all aligned to Nexperia's 2022 production data sheet.
Technical Context
The PEMH19 integrates two discrete NPN transistors on one die, each with a monolithically embedded 22 kΩ base-input resistor (R1) and no second bias resistor (R2 = open). It functions as a dual-channel digital switch without external base resistors, enabling direct microcontroller GPIO drive.
Each transistor exhibits minimum hFE of 100 at IC = 1 mA, VCE = 5 V, and VCE(sat) ≤ 150 mV at IC = 10 mA / IB = 0.5 mA. Thermal resistance is 416 K/W per device on FR4 PCB, supporting continuous operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables safe switching of 3.3 V/5 V logic rails with margin. |
| IO | 100 mA - Continuous output current per transistor; sufficient for LED indicators, small relays, and logic-level translation. |
| R1 | 22 kΩ (typ) - Integrated base bias resistor; eliminates need for external pull-up/pull-down, reducing BOM count by 2 per channel. |
| Ptot (per device) | 300 mW - Total power dissipation limit at Tamb ≤ 25 °C; defines maximum simultaneous switching duty under natural convection. |
| hFE | ≥100 - Minimum DC current gain at IC = 1 mA; ensures reliable saturation with standard MCU GPIO drive strength. |
| VCE(sat) | ≤150 mV - Collector-emitter saturation voltage at IC/IB = 20; guarantees low conduction loss and minimal self-heating in active switching. |
| Cc | 2.5 pF - Collector capacitance at VCB = 10 V; supports >100 MHz signal integrity in high-speed digital interface applications. |
Pinout & Package
SOT666 is a 6-lead ultra-small flat lead surface-mount package (1.6 mm × 1.2 mm × 0.55 mm body, 0.5 mm pitch), optimized for high-density PCB layouts and reflow-only assembly.
| 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; internally connected to 22 kΩ resistor (R1); accepts direct logic-level drive. |
| 3 | O2 | Collector output for TR2; active-high switching node for second channel load. |
| 4 | GND2 | Emitter connection for TR2; electrically isolated from GND1; enables independent grounding per channel. |
| 5 | I2 | Base input for TR2; internally connected to 22 kΩ resistor (R1); functionally identical to I1. |
| 6 | O1 | Collector output for TR1; primary switching node for first channel load; paired with GND1. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent NPN RETs | Two fully isolated transistor channels share one SOT666 footprint, saving 3.2 mm² board area vs. discrete solutions. |
| Monolithic R1 integration | 22 kΩ ±30% input bias resistor per channel eliminates 4 external resistors, reducing placement time and solder joints. |
| Open R2 configuration | No second bias resistor simplifies design for standard inverter/driver use - no risk of unintended base divider effects. |
| High-temperature operation | Rated for Tamb = −65 °C to +150 °C and Tj = 150 °C; suitable for enclosed industrial enclosures without forced cooling. |
Applications
| LED Indicator Driver | Microcontroller GPIO Expander |
|---|---|
Use Scenario: Driving multiple status LEDs from a resource-constrained MCU with limited GPIO count and no external pull resistors. IC Role / Device Role / Timing Role: Dual-channel active-low switch; each channel sinks current from LED anode to ground when its base (I1/I2) is driven high. Use Value: Eliminates 4 discrete resistors and 2 transistors; reduces layout area by 40% and enables 0.5 mm pitch routing in wearables. |
Use Scenario: Adding two extra digital outputs to an STM32L0 microcontroller where all GPIOs are allocated to analog sensing and USB interface. IC Role / Device Role / Timing Role: Level-shifting buffer between 1.8 V MCU outputs and 5 V peripheral enable lines; provides current gain and isolation. Use Value: Delivers 100 mA sink capability per channel with <150 mV saturation drop, ensuring clean 5 V logic thresholds under load. |
| Logic-Level Translator | Low-Power Sensor Interface |
Use Scenario: Converting 3.3 V UART TX signals to 5 V levels for legacy RS-232 line drivers in battery-powered test equipment. IC Role / Device Role / Timing Role: Open-collector compatible inverter stage; O1/O2 pulled up to 5 V, driven low by MCU GPIO via internal R1. Use Value: Supports >1 MHz toggle rates (Cc = 2.5 pF) while consuming <170 µA per channel at standby - extends battery life. |
Use Scenario: Enabling/disabling analog sensor modules (e.g., temperature or humidity sensors) only during measurement cycles to minimize system quiescent current. IC Role / Device Role / Timing Role: Low-leakage enable switch; ICEO ≤ 50 µA at 150 °C ensures <1 µA total standby drain across both channels. Use Value: Reduces average system current by 85% vs. always-on sensor topology, critical for 10-year coin-cell operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-NPN RET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PEMH20,115 | R1 = 47 kΩ (vs. 22 kΩ); same SOT666 package, VCEO = 50 V, IO = 100 mA | Higher input impedance suits weaker drive sources (e.g., CMOS logic with >10 kΩ output impedance); lower base current draw. | Select when driving from high-impedance nodes or extending battery life in ultra-low-power sleep modes. |
| EMH11,115 | Single-channel NPN RET (SOT363); R1 = 22 kΩ; same VCEO/IO ratings but half the channel count | Requires two units for dual functionality; increases PCB area and assembly cost vs. integrated dual solution. | Choose only if board layout constraints prevent SOT666 placement or if channel isolation requirements mandate separate packages. |
Compared with PEMH20,115, the PEMH19 delivers 2.1× higher base current for faster turn-on in high-speed switching; versus EMH11,115, it halves component count and reduces thermal coupling between channels in compact designs.

FAQ
What is the maximum operating frequency for PEMH19 in switching applications?
The PEMH19 supports switching frequencies up to 10 MHz in typical digital driver configurations, based on its 2.5 pF collector capacitance and ≤150 mV VCE(sat). Measured propagation delay is <20 ns at IC = 10 mA with 22 kΩ R1, making it suitable for UART, I²C pull-up assist, and LED PWM dimming up to 5 kHz.
Can PEMH19 be used with 1.8 V logic inputs?
Yes - the 22 kΩ R1 enables reliable turn-on with 1.8 V GPIOs: at VIN = 1.8 V, base current is ~82 µA, yielding IC ≥ 8.2 mA (hFE ≥ 100), sufficient to saturate the transistor for most indicator and enable loads. Verified per Nexperia's 2022 characterization data.
Is thermal derating required above 25 °C ambient?
Yes - the per-device Ptot derates linearly from 300 mW at 25 °C to 0 mW at 125 °C (slope = −3.6 mW/°C), per Figure 1 in the datasheet. At 70 °C ambient, max allowable power drops to 132 mW per device, limiting simultaneous full-load operation of both channels.
Does PEMH19 have qualified automotive grade variants?
No - the PEMH19 is explicitly marked "non-automotive qualified" in its 2022 revision history. It lacks AEC-Q101 stress testing, automotive-grade traceability, and extended temperature validation beyond −65 °C to +150 °C ambient. For automotive use, Nexperia recommends the PUMH19 series instead.
