Nexperia USA Inc. PEMH11,315

Overview

PEMH11 from Nexperia is a dual NPN resistor-equipped transistor (RET) in SOT666 package, integrating two matched 50 V V_CEO, 100 mA output transistors with built-in 10 kΩ input bias resistors (R1 = R2 = 10 kΩ) and unity R2/R1 ratio. It functions as a compact, pre-biased digital switching pair for level translation and signal buffering in space-constrained logic interfaces.

For engineers reviewing the PEMH11 datasheet, PEMH11 pinout, PEMH11 application, or PEMH11 equivalent, this device is selected for low-power digital control tasks where reduced external component count, consistent turn-on behavior across temperature, and ultra-small 1.6 mm × 1.2 mm footprint are critical - especially in portable sensor nodes and I/O expander interface circuits.

Technical Context

The PEMH11 integrates two independent NPN transistors, each with monolithically embedded base bias resistors (R1 = 10 kΩ, R2 = 10 kΩ), eliminating discrete base resistors and ensuring stable DC biasing without layout sensitivity. Its R2/R1 ratio of 1.0 ±0.2 enables predictable saturation and cutoff thresholds across -40 °C to 100 °C.

Each transistor supports 50 V collector-emitter breakdown (V_CEO) and delivers 100 mA output current with typical V_CE(sat) ≤150 mV at I_C = 10 mA / I_B = 0.5 mA. Thermal resistance is 417 K/W per device on FR4 PCB, enabling operation up to 150 °C junction temperature under reflow-soldered conditions.

FAQ

What is the maximum operating temperature for PEMH11 in continuous use?

The PEMH11 has a maximum junction temperature (T_j) of 150 °C and a storage temperature range of -65 °C to +150 °C. When mounted on a standard FR4 PCB with single-sided 35 μm copper, its thermal resistance is 417 K/W per device, allowing full 100 mA operation up to 75 °C ambient temperature before derating begins.

Can PEMH11 be used with 1.8 V logic inputs?

No - the PEMH11's VI(on) is specified from 1.8 V (min) to 2.5 V (max) at I_C = 10 mA, meaning reliable turn-on requires ≥1.8 V input. At 1.8 V, performance is marginal and highly temperature-dependent; 3.3 V or 5 V logic is recommended for robust operation across industrial temperature ranges.

Are the two transistors electrically isolated from each other?

Yes - the PEMH11 contains two fully independent NPN transistors with separate emitter (GND1 and GND2), base (I1 and I2), and collector (O1 and O2) terminals. There is no internal electrical connection between the two channels, enabling use in isolated signal paths or split-ground systems.

Does PEMH11 support PWM switching at 100 kHz?

Yes - with f_T = 230 MHz and typical V_CE(sat) ≤150 mV, the PEMH11 supports clean digital switching up to at least 20 MHz edge rates. At 100 kHz PWM, switching losses remain negligible (<5% of total power), and thermal rise is well within limits when operated below 100 mA per channel.
