Nexperia USA Inc. PMBT2907AQAZ

Overview

PMBT2907AQAZ from Nexperia is a PNP bipolar junction transistor optimized for high-speed switching in space-constrained automotive and portable electronics. It delivers −60 V V_CEO, −600 mA I_C, and 300 ns storage time in a 1.1 mm × 1.0 mm × 0.37 mm DFN1010D-3 (SOT1215) package, supporting low-voltage load switching in battery-powered control circuits.

For engineers reviewing the PMBT2907AQAZ datasheet, PMBT2907AQAZ pinout, PMBT2907AQAZ application, or PMBT2907AQAZ equivalent, key selection criteria include its AEC-Q101 qualification, ultra-thin thermal-enhanced package, −1.6 V V_CE(sat) at −500 mA, and compatibility with automated optical inspection (AOI) of solder joints.

Technical Context

This PNP transistor operates as a saturated switch in low-side driver configurations, with DC current gain (h_FE) ranging from 100 at −150 mA to 50 at −500 mA under V_CE = −10 V. Its −5 V V_EBO and −60 V V_CBO support robust base-emitter and collector-base voltage margins in 12 V and 24 V automotive subsystems.

Switching performance is defined by 15 ns delay, 30 ns rise, and 365 ns turn-off time under IC = −150 mA, IB_on = −15 mA, and IB_off = 15 mA conditions. Thermal resistance R_th(j-a) reaches 133 K/W when mounted on a 4-layer FR4 PCB with 1 cm² collector pad - critical for sustained pulsed operation.

FAQ

What is the maximum allowable junction temperature for PMBT2907AQAZ?

The absolute maximum junction temperature (T_j) is 150 °C, as specified in the limiting values table. Operation above this threshold risks permanent degradation of h_FE and increased leakage. Derating is required above 25 °C ambient per the power derating curve - e.g., maximum P_tot drops to 525 mW at 75 °C ambient on a 4-layer PCB.

Can PMBT2907AQAZ be used in linear amplifier configurations?

Yes - its h_FE stability (100–300 at −150 mA, 50 min at −500 mA) and low V_BE(sat) (−2.6 V) support Class-A biasing in low-noise preamplifier stages. However, thermal limitations require careful heatsinking; linear operation above 100 mW demands the 4-layer PCB thermal pad configuration to maintain T_j < 125 °C.

How does the DFN1010D-3 package affect PCB layout for thermal performance?

The DFN1010D-3 requires a dedicated 1 cm² copper pour connected to Pin 3/4 (collector) on the bottom layer, with ≥4 thermal vias to inner ground/power planes. The footprint in Figure 16 specifies 0.75 mm pitch and 0.4 mm solder mask openings - undersizing the pad or omitting vias increases R_th(j-a) by >50%, risking thermal runaway at rated current.

Is there a complementary NPN device with matching package and qualification?

Yes - the PMBT2222AQA is the designated NPN complement, sharing identical DFN1010D-3 packaging, AEC-Q101 qualification, −600 mA I_C, and −60 V V_CEO. Both devices are optimized for matched pair usage in push-pull drivers or differential sensing front-ends where thermal and dimensional symmetry is critical.
