Nexperia USA Inc. PEMH10,115

Overview

PEMH10 from Nexperia is an NPN/NPN resistor-equipped double transistor (RET) in SOT666 package, rated for 50 V V_CEO, 100 mA output current per transistor, with integrated bias resistors R1 = 2.2 kΩ and R2 = 47 kΩ. It functions as a dual low-side switching element in digital logic interface and peripheral driver circuits.

For engineers reviewing the PEMH10 datasheet, PEMH10 pinout, PEMH10 application, or PEMH10 equivalent, this device is selected for space-constrained PCBs requiring reduced external component count, simplified base drive, and guaranteed DC current gain ≥100 at 10 mA collector current.

Technical Context

The PEMH10 integrates two matched NPN transistors with on-chip base bias networks-R1 connects input to base, R2 connects base to emitter-enabling direct TTL/CMOS-level input drive without external resistors. Each transistor operates independently with open-base V_CEO = 50 V and I_O = 100 mA rating.

Its SOT666 package supports 0.5 mm pitch, 1.6 mm × 1.2 mm footprint, and thermal resistance R_th(j-a) = 417 K/W (per device), optimized for reflow-only assembly on FR4 PCBs. The built-in R2/R1 ratio of 21 ±5 ensures consistent turn-on behavior across temperature (−40 °C to +150 °C).

FAQ

Is PEMH10 suitable for 1.8 V logic-level input drive?

Yes. VI(on) is specified from 0.75 V (typical) to 1.1 V (max) at I_C = 5 mA, ensuring reliable turn-on with 1.8 V CMOS outputs. VI(off) remains below 0.6 V, providing adequate noise margin against false triggering in low-voltage systems.

Can PEMH10 replace two separate BC847B transistors with external bias resistors?

Yes-provided the application uses NPN low-side switching and does not require independent base bias tuning. PEMH10 integrates R1 = 2.2 kΩ and R2 = 47 kΩ per channel, eliminating four external resistors and reducing PCB area by ~65% versus discrete implementation.

What is the maximum ambient temperature for continuous 100 mA operation per channel?

At 100 mA per channel and Tamb = 75 °C, total power dissipation reaches ~200 mW (per device), staying within the 300 mW derated limit for FR4 PCB mounting. Operation above 75 °C requires derating per Figure 1; full 100 mA is supported up to 75 °C ambient.

Does PEMH10 support reflow soldering only, or can it be hand-soldered?

Reflow soldering is the only recommended method per Nexperia's qualification. Hand-soldering risks thermal damage due to the SOT666 package's small thermal mass and tight 0.5 mm pitch; hot-air rework tools with precise temperature profiling are required if manual repair is unavoidable.
