Product details
Overview
PEMH16 from Nexperia is a dual NPN resistor-equipped transistor (RET) in SOT666 package, integrating two matched NPN transistors each with built-in bias resistors R1 = 22 kΩ and R2 = 47 kΩ, rated for 50 V VCEO and 100 mA output current per transistor, used for digital logic interfacing and low-current peripheral driving in space-constrained PCBs.
For engineers reviewing the PEMH16 datasheet, PEMH16 pinout, PEMH16 application, or PEMH16 equivalent, this page delivers verified pin functions, exact resistor values, thermal resistance (416 K/W per device), junction temperature limit (150 °C), and validated alternatives for discrete transistor replacement in 3.3 V/5 V logic-level control circuits.
Technical Context
The PEMH16 integrates two independent NPN transistors on a single die, each with dedicated base-input resistors (R1) and base-collector feedback resistors (R2), enabling direct connection to CMOS/TTL outputs without external biasing. Its R2/R1 ratio of 2.1 ensures stable saturation under varying temperature conditions.
Designed for digital switching-not linear amplification-the device specifies VI(on) = 1.1 V (typ) at IC = 2 mA and VI(off) = 0.8 V (typ) at IC = 100 µA, confirming robust noise immunity and clean logic-level translation between microcontroller GPIOs and load-side circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V maximum - supports reliable switching in 24 V industrial I/O and 5 V/3.3 V logic systems with margin |
| IO | 100 mA per transistor - sufficient for LED drivers, small relays, and gate control of power MOSFETs |
| R1 | 22 kΩ ±30% - sets base current for predictable turn-on with standard MCU output voltages |
| R2/R1 | 2.1 (1.7–2.6) - provides internal feedback to stabilize operating point across temperature and process variation |
| Ptot (per device) | 300 mW at Tamb ≤ 25 °C - enables operation without heatsinking in compact consumer and IoT PCB layouts |
| Rth(j-a) | 416 K/W - defines thermal derating curve when mounted on FR4 with standard reflow footprint |
| VCE(sat) | 150 mV max at IC = 10 mA, IB = 0.5 mA - minimizes conduction loss in low-power switching applications |
Pinout & Package
SOT666 plastic surface-mount package: 6-pin, 0.5 mm pitch, 1.6 mm × 1.2 mm × 0.55 mm body height, designed for high-density routing and automated assembly.
| 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 signal directly from MCU or buffer |
| 3 | O2 | Collector output for TR2 - drives load connected between O2 and VCC |
| 4 | GND2 | Emiter connection for TR2 - independent ground return for second transistor |
| 5 | I2 | Base input for TR2 - electrically isolated from I1, enabling dual independent switching |
| 6 | O1 | Collector output for TR1 - configured as low-side switch with GND1 as emitter reference |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET topology | Two fully independent NPN transistors with matched internal R1/R2 networks - eliminates need for 4 external bias resistors |
| Standardized SOT666 footprint | Compatible with JEDEC MS-012AC outline - enables drop-in replacement and automated optical inspection |
| Guaranteed R2/R1 ratio | 2.1 ±24% - ensures consistent gain stabilization and reduces sensitivity to supply voltage drift |
| Low VI(on)/VI(off) thresholds | VI(on) = 1.1 V (typ), VI(off) = 0.8 V (typ) - compatible with 1.8 V, 3.3 V, and 5 V logic families without level shifting |
Applications
| LED Driver Interface | Microcontroller GPIO Expander |
|---|---|
Use Scenario: Driving multiple status LEDs from limited GPIO pins on an ARM Cortex-M0+ MCU. IC Role / Device Role / Timing Role: Dual low-side switch translating logic-high signals into controlled current paths through LEDs.

Use Value: Supports 100 mA sink capability per channel while maintaining <150 mV saturation voltage - preserves timing integrity in fast-switching indicator control. |
| Logic-Level Signal Translator | Small Relay Driver |
Use Scenario: Interfacing 1.8 V FPGA I/O banks to 5 V legacy control logic in test equipment. IC Role / Device Role / Timing Role: Bidirectional DC-coupled level shifter using saturated switching mode for unidirectional signal translation.

IC Role / Device Role / Timing Role: Low-side driver providing 100 mA coil current with integrated base biasing. Use Value: Built-in R1/R2 eliminates risk of transistor damage due to incorrect external resistor selection - improves field reliability over discrete solutions. |
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 |
|---|---|---|---|
| PEMD16 | NPN/PNP complementary pair - different polarity configuration per channel | Required where one channel must source current (e.g., high-side LED drive) while the other sinks | Select PEMD16 only when mixed-polarity switching is needed; not interchangeable with PEMH16 in same-circuit roles |
| PEMB16 | PNP/PNP RET - both transistors are PNP, with inverted logic polarity | Suitable for high-side switching or active-low enable circuits requiring sourcing capability | Choose PEMB16 when driving loads referenced to VCC; requires inverted control signals versus PEMH16 |
Compared with PEMD16 and PEMB16, the PEMH16 uniquely supports dual low-side switching with identical NPN polarity and positive-logic compatibility - simplifying firmware design and eliminating level inversion logic in GPIO-constrained embedded systems.

FAQ
Is PEMH16 suitable for analog amplification applications?
No. The PEMH16 is characterized and specified exclusively for digital switching operation. Its datasheet provides no hFE curves beyond 5 mA, no linearity specifications, and no small-signal parameters. It lacks bias stability for linear regions and is not intended for amplifier use.
What is the maximum allowable input voltage at I1 or I2 pins?
The absolute maximum input voltage is +40 V for positive signals and −7 V for negative transients, per the VI specification in Table 5. Operation above 5.5 V is not recommended unless externally clamped, as internal R1/R2 networks are optimized for 1.8–5 V logic levels.
Can PEMH16 be used in automotive applications?
No. The 29 December 2022 datasheet explicitly states "Product(s) changed to non-automotive qualification" in the revision history. PEMH16 is not AEC-Q101 qualified, has no automotive-grade screening, and carries no warranty for automotive use per Nexperia's legal disclaimers.
Does PEMH16 require external decoupling capacitors?
No. As a DC-coupled digital switch with no RF or high-speed requirements, PEMH16 does not require decoupling. However, local 100 nF ceramic capacitors are recommended at VCC nodes of driven loads (e.g., relay coils or LED strings) to suppress inductive kickback and ensure stable switching behavior.
