Nexperia USA Inc. PQMB11Z

Overview

PQMB11 from Nexperia is a dual PNP resistor-equipped transistor (RET) in a DFN1010B-6 (SOT1216) package, configured as two independent PNP transistors each with integrated 10 kΩ input bias resistors (R1 = R2 = 10 kΩ). It delivers −100 mA output current per transistor, supports −50 V collector-emitter voltage, and is AEC-Q101 qualified for automotive signal conditioning and digital logic interfacing.

For engineers reviewing the PQMB11 datasheet, PQMB11 pinout, PQMB11 application, or PQMB11 equivalent, this device serves as a space-optimized, bias-resistor-integrated replacement for discrete PNP pairs in low-current peripheral drivers, IC input control, and mobile power management circuits where component count reduction and ultra-thin mounting are critical.

Technical Context

The PQMB11 integrates two matched PNP transistors on a single die, each with precision-built 10 kΩ base-input resistors (R1) and equal-value feedback resistors (R2), yielding an R2/R1 ratio of 1.0 ±0.2. Its dual-emitter, dual-collector topology enables independent switching control with shared ground terminals (Pin 1 and Pin 4).

Designed for digital interface applications, it operates with guaranteed VI(on) ≤ −1.8 V at −10 mA IC and VI(off) ≥ −1.1 V at −100 µA ICEO, ensuring robust noise margin in 3.3 V and 5 V logic systems. Thermal resistance is 357 K/W (per device) on FR4 PCB, supporting continuous operation up to 150 °C junction temperature.

Key Specifications

Pinout & Package

FAQ

Is PQMB11 pin-compatible with PQMH11?

Yes-PQMB11 and PQMH11 share identical DFN1010B-6 (SOT1216) packaging and pin assignment (GND1/I1/O2/GND2/I2/O1), enabling drop-in replacement in layouts designed for the NPN/NPN variant. However, polarity reversal means logic behavior inverts: PQMH11 sources current while PQMB11 sinks it, requiring firmware or schematic adjustment for functional equivalence.

What is the maximum ambient temperature for continuous operation?

The PQMB11 supports continuous operation up to +150 °C ambient temperature when mounted on an FR4 PCB with standard footprint, as confirmed by its specified Tamb range (−55 °C to +150 °C) and thermal derating curve showing usable power dissipation down to Tj = 150 °C. Derating begins above +25 °C ambient at 357 K/W.

Can PQMB11 drive a 5 V relay coil directly?

No-PQMB11 is rated for −100 mA per channel and −50 V VCEO, but typical 5 V relay coils draw 20–70 mA at turn-on and require ≥1.5 V VCE(sat) headroom for reliable release. Its −150 mV VCEsat is insufficient to guarantee full de-energization; a series current-limiting resistor or dedicated driver stage is required for safe relay control.

Does PQMB11 include ESD protection?

No-PQMB11 does not integrate on-chip ESD protection diodes. Per Nexperia's datasheet, it meets HBM Class 1B (≥2 kV) only when assembled with appropriate board-level protection (e.g., TVS diodes on I/O lines). For direct I/O exposure in handheld or connector-facing applications, external ESD clamps are mandatory.
