Nexperia USA Inc. PIMP32PAX

Overview

PIMP32PA from Nexperia is a PNP/PNP resistor-equipped double transistor (RET) in a DFN2020-6 (SOT1118) leadless SMD package, rated for −50 V V_CEO, −500 mA output current per transistor, with integrated bias resistors R1 = 2.2 kΩ and R2 = 10 kΩ. It serves as a compact, dual-channel level-shifting and load-switching device in digital control circuits, replacing discrete BJT + resistor combinations in space-constrained PCBs.

For engineers reviewing the PIMP32PA datasheet, PIMP32PA pinout, PIMP32PA application, or PIMP32PA equivalent, this part is selected for high-density digital switching where reduced component count, simplified base drive, and thermal performance on FR4 PCBs are critical - especially in industrial I/O modules and logic-level interface stages.

Technical Context

This dual PNP RET integrates two matched PNP transistors with monolithically embedded base bias networks: R1 (2.2 kΩ) connects input to base of each transistor, while R2 (10 kΩ) ties base to emitter, forming a fixed-current-input configuration. The structure enables direct TTL/CMOS-compatible switching without external base resistors.

Each transistor operates independently with verified −50 V collector-emitter breakdown, −500 mA DC output capability, and low −100 mV V_CE(sat) at −50 mA/−2.5 mA drive. Thermal resistance ranges from 125 K/W (4-layer PCB, enhanced pad) to 348 K/W (standard single-layer layout), confirming its suitability for thermally constrained environments.

FAQ

What is the maximum operating temperature for PIMP32PA?

The junction temperature limit is 150 °C, and the ambient operating range is −55 °C to +150 °C. Derated power dissipation must be applied above 25 °C ambient - for example, total device power drops to 500 mW at 75 °C ambient on a standard FR4 PCB (Table 5, condition [1]). Thermal design should reference Fig. 1 curves for precise derating.

Can PIMP32PA drive inductive loads directly?

Yes, it can switch inductive loads up to −500 mA, but an external flyback diode is mandatory across the load to clamp inductive kickback. The −50 V V_CEO rating provides margin for typical 24 V systems, but transient spikes exceeding this require suppression - confirmed by Nexperia's application note AN10272 on RET inductive switching.

Is the DFN2020-6 package compatible with standard reflow profiles?

Yes, PIMP32PA is qualified for JEDEC J-STD-020D-compliant lead-free reflow, with peak temperature up to 260 °C. The recommended solder land pattern matches Fig. 15 (0.49 mm × 0.49 mm pads, 0.65 mm pitch), and thermal pad exposure improves heat transfer - critical for achieving the 125 K/W R_th(j-a) spec on 4-layer boards.

How does the R2/R1 ratio affect switching behavior?

The fixed R2/R1 = 4.55 ratio ensures stable base current division, resulting in consistent VI(on) = −0.95 V and VI(off) = −0.65 V thresholds across temperature (Fig. 8–9). This eliminates variability seen in discrete designs and guarantees reliable turn-on/turn-off margins for 3.3 V logic, even at −40 °C or +100 °C.
