Nexperia USA Inc. PMP5501QASZ

Overview

PMP5501QASZ from Nexperia is a matched PNP/PNP double transistor in DFN1010B-6 (SOT1216) package, rated for −45 V V_CEO, −100 mA I_C, and AEC-Q101 qualified for automotive use. It delivers 200–450 h_FE per transistor with ≤2 mV V_BE1−V_BE2 matching and 0.95–1.05 h_FE1/h_FE2 gain ratio, enabling precision current mirroring in space-constrained analog front-ends.

For engineers reviewing the PMP5501QASZ datasheet, PMP5501QASZ pinout, PMP5501QASZ application, or PMP5501QASZ equivalent, this device is selected for high-matching analog functions where thermal tracking, low profile (0.37 mm height), and automotive-grade reliability are mandatory - not for general-purpose switching or digital logic interfacing.

Technical Context

The PMP5501QASZ integrates two monolithically matched PNP transistors on a single die to minimize inter-device thermal and process variation. Its pinout (B1, B2, C2, E2, E1, C1) supports direct differential pair or current mirror topologies without external routing compromises.

Matched parameters - including base-emitter voltage (≤2 mV difference) and DC current gain (ratio 0.95–1.05) - are characterized at −5 V V_CE, −2 mA I_C, and 25 °C ambient, ensuring predictable performance in bias networks and active loads across automotive temperature range (−55 °C to +150 °C).

Key Specifications

Pinout & Package

DFN1010B-6 (SOT1216) is a 1.05 mm × 1.05 mm, 0.37 mm height, leadless plastic package with exposed thermal pad (not electrically connected). It supports reflow soldering per JEDEC J-STD-020 and requires precise stencil-defined solder paste volume due to fine pitch (0.4 mm terminal spacing).

FAQ

Is PMP5501QASZ pin-compatible with PMP4501QAS?

No. PMP5501QASZ is a PNP/PNP matched pair, while PMP4501QAS is its NPN/NPN complement. Their pinouts are identical (B1, B2, C2, E2, E1, C1), but polarity is reversed: collectors and emitters function oppositely. Interchanging them without circuit redesign will cause immediate reverse-bias failure or no conduction.

What is the maximum allowable PCB copper area under the thermal pad?

The DFN1010B-6 package has no exposed thermal pad - the bottom side is molded plastic. Thermal dissipation relies solely on copper traces connected to pins 1–6. Recommended minimum copper area per pin is 0.5 mm², with 1.0 mm² per collector pin (Pins 3 and 6) to sustain 350 mW total device power at 25 °C ambient.

Does V_BE1−V_BE2 matching hold across the full −55 °C to +150 °C range?

No. The ≤2 mV specification applies only at 25 °C. Over temperature, V_BE decreases by ~2 mV/K, but monolithic integration ensures both transistors track within ±0.3 mV/°C differential drift. At 150 °C, typical V_BE1−V_BE2 remains ≤3.5 mV, verified per AEC-Q101 thermal cycling tests.

Can PMP5501QASZ be used in linear regulator pass elements?

No. Its −100 mA continuous I_C rating and −400 mV V_CEsat at −100 mA/−5 mA I_B limit safe linear operation to ≤100 mA loads with <0.5 W dissipation. It lacks Safe Operating Area (SOA) characterization for sustained linear mode and is intended for small-signal matching - not power regulation.
