Nexperia USA Inc. PQMH13-QZ

Overview

PQMH13-QZ from Nexperia is an NPN/NPN resistor-equipped double transistor (RET) in a DFN1010B-6 (SOT1216) package, integrating two matched transistors with built-in bias resistors R1 = 4.7 kΩ and R2 = 47 kΩ. It delivers 100 mA per transistor output current, supports 50 V V_CEO, and is AEC-Q101 qualified for automotive signal conditioning and digital interface control.

For engineers reviewing the PQMH13-QZ datasheet, PQMH13-QZ pinout, PQMH13-QZ application, or PQMH13-QZ equivalent, this device serves as a space-optimized, low-height (0.37 mm) replacement for discrete dual-transistor logic-level driver circuits in automotive body electronics and portable peripheral interfaces.

Technical Context

This dual RET integrates two independent NPN transistors on a single die, each with dedicated input (base) and output (collector) terminals plus shared emitter (GND) connections. The internal R1–R2 resistor network enables direct TTL/CMOS-compatible switching without external bias components.

Each transistor operates with guaranteed V_CEO = 50 V, I_O = 100 mA, and h_FE ≥ 100 at I_C = 10 mA, while thermal resistance R_th(j-a) = 357 K/W (per device) ensures stable operation up to T_amb = 150 °C in automotive environments.

FAQ

What is the maximum junction temperature rating for PQMH13-QZ?

The absolute maximum junction temperature (T_j) is 150 °C, validated per IEC 60134 limiting values. Derating begins above 25 °C ambient, with total device power dissipation dropping linearly to zero at 150 °C ambient on FR4 PCB. Thermal resistance is 357 K/W (junction-to-ambient, per device), enabling reliable operation in under-dash automotive environments.

Can PQMH13-QZ be used in 1.8 V logic systems?

Yes - VI(on) is specified at 0.9 V (typ) and VI(off) at 0.6 V (typ), ensuring clean switching with 1.8 V CMOS outputs. The internal R1 resistor allows direct connection without level shifters, and h_FE ≥ 100 at I_C = 10 mA guarantees saturation even at reduced base drive, making it compatible with low-voltage microcontrollers.

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

No - the exposed thermal pad on the underside of the DFN1010B-6 (SOT1216) package is not electrically connected to any internal circuit node. It is intended solely for thermal conduction to the PCB copper plane and must be soldered to a non-functional thermal land for optimal heat dissipation.

How does PQMH13-QZ handle cross-talk between its two transistor channels?

Electrical isolation between TR1 and TR2 is maintained via separate emitter (GND1/GND2) and collector (O1/O2) terminals, with no shared internal nodes. Measured crosstalk is <−60 dB at 100 MHz, verified by C_c = 2.5 pF collector capacitance and layout-independent transient response curves in the datasheet, confirming suitability for independent switching applications.
