NXP Semiconductors 2PD602AQ,115

Overview

2PD602AQ,115 from Nexperia is an NPN general purpose transistor in SC-59 (SOT346) package, rated for 50 V V_CEO, 500 mA I_C, and 250 mW P_tot, with DC current gain h_FE of 85–170 at 150 mA/10 V, used in low-voltage switching and amplification circuits in consumer and industrial electronics.

For engineers reviewing the 2PD602AQ,115 datasheet, 2PD602AQ,115 pinout, 2PD602AQ,115 application, or 2PD602AQ,115 equivalent, key selection criteria include its SC-59 footprint compatibility, guaranteed h_FE binning (Q-code), 140 MHz f_T, low V_CE(sat) ≤ 600 mV at 300 mA/30 mA drive, and thermal resistance R_{th j-a} = 500 K/W on FR4.

Technical Context

This discrete NPN bipolar junction transistor operates in linear or saturated switching modes with base-controlled current amplification. Its design supports DC and low-frequency AC signal handling up to ~140 MHz transition frequency, with defined cut-off leakage (ICBO ≤ 10 nA at 25 °C) and robust thermal limits (T_j ≤ 150 °C).

It is specified for operation on standard FR4 PCBs without heatsinking, with absolute maximum ratings including 60 V V_CBO, 5 V V_EBO, and 1 A I_CM peak collector current-enabling reliable use in compact, cost-sensitive board-level designs where moderate gain and voltage headroom are required.

FAQ

What is the package type and lead count of the 2PD602AQ,115?

The 2PD602AQ,115 uses the SC-59 package, also known as SOT346 or TO-236, a 3-lead surface-mount plastic package standardized by JEDEC. Its pinout is Base (pin 1), Emitter (pin 2), Collector (pin 3), and it is compatible with automated pick-and-place and reflow soldering processes.

What does the 'Q' suffix in 2PD602AQ,115 indicate?

The 'Q' in 2PD602AQ,115 denotes the h_FE gain bin: specifically, a DC current gain range of 85–170 measured at I_C = 150 mA and V_CE = 10 V. This binning ensures consistent base drive requirements across production units of the 2PD602AQ,115.

Can the 2PD602AQ,115 replace a 2N3904 in existing designs?

The 2PD602AQ,115 is not a direct replacement for the 2N3904 due to differences in package (SC-59 vs TO-92), pinout, and electrical specs-especially lower V_CEO (50 V vs 40 V) and higher I_C (500 mA vs 200 mA). While functionally similar, PCB layout and thermal validation are required before substituting the 2PD602AQ,115.

What is the maximum operating junction temperature for the 2PD602AQ,115?

The 2PD602AQ,115 has a maximum junction temperature (T_j) of 150 °C, as specified in its Absolute Maximum Ratings table. This limit must be respected under all operating conditions, and actual junction temperature depends on ambient temperature, power dissipation, and PCB thermal design per its R_{th j-a} = 500 K/W rating.

Is there a PNP complement to the 2PD602AQ,115?

Yes-the PNP complement to the 2PD602AQ,115 is the 2PB710A, which shares the same SC-59 package and complementary voltage/current ratings. Both devices are designed for matched pair use in push-pull or differential configurations where polarity symmetry is required.
