Nexperia USA Inc. PQMH11Z

Overview

PQMH11 from Nexperia is a dual NPN resistor-equipped transistor (RET) in a DFN1010B-6 (SOT1216) package, integrating two matched NPN transistors each with 10 kΩ input bias resistors (R1 = R2 = 10 kΩ) and rated for 50 V V_CEO, 100 mA output current, and AEC-Q101 qualification. It functions as a compact, low-height (0.37 mm) digital switching pair for space-constrained automotive and mobile peripheral control.

For engineers reviewing the PQMH11 datasheet, PQMH11 pinout, PQMH11 application, or PQMH11 equivalent, this device supports high-density PCB layouts requiring dual-channel logic-level switching with built-in biasing, reduced component count, and automotive-grade reliability without external base resistors.

Technical Context

The PQMH11 integrates two independent NPN transistors on a single die, each with monolithically embedded R1 (input) and R2 (base-emitter feedback) resistors-both nominally 10 kΩ with ±30% tolerance and ratio R2/R1 = 1.0 ±0.2. Its dual-transistor topology enables synchronous or independent switching of two digital loads using only input signals and ground connections.

Designed for direct interfacing with CMOS/TTL logic, it features VI(on) = 1.8–2.5 V and VI(off) = 0.8–1.1 V at 25 °C, ensuring robust noise margin and guaranteed turn-on/turn-off across temperature. The DFN1010B-6 package provides thermal resistance R_th(j-a) = 357 K/W (per device) on FR4 PCB, supporting continuous operation up to 150 °C junction temperature.

FAQ

What is the maximum operating temperature for PQMH11 in continuous use?

The PQMH11 has a maximum junction temperature (T_j) of 150 °C and an ambient operating range of −55 °C to +150 °C. When mounted on a standard FR4 PCB with single-sided copper, its thermal resistance is 357 K/W per device, allowing continuous 100 mA operation up to 85 °C ambient with full derating above that point per Figure 2 in the datasheet.

Can PQMH11 replace two separate BC847BV transistors in a design?

Yes-PQMH11 replaces two BC847BV transistors plus four external 10 kΩ base resistors, delivering identical DC current gain (h_FE ≥30 at 5 mA), V_CE(sat) ≤150 mV, and 50 V V_CEO. Its integrated biasing eliminates layout sensitivity to resistor placement and improves channel-to-channel matching in timing-critical applications.

Is the exposed pad on the DFN1010B-6 package electrically connected?

No-the DFN1010B-6 package used for PQMH11 has no internal connection to the exposed thermal pad. The pad serves only mechanical anchoring and thermal conduction to the PCB; it must be soldered to a non-powered copper pour for optimal thermal performance but requires no electrical net assignment.

How does PQMH11 handle input voltage transients during hot-swap events?

PQMH11 withstands input transients up to ±10 V (VI rating) and features VI(off) ≥0.8 V and VI(on) ≤2.5 V at 25 °C, ensuring reliable state retention during brief supply glitches. Its 100 nA ICBO and 1 µA ICEO at 30 V guarantee minimal leakage-induced false triggering even after repeated hot-insertion cycles in USB-C or docking station applications.
