Nexperia USA Inc. 2PC4617QMB,315

Overview

2PC4617QMB from Nexperia is an AEC-Q101 qualified NPN general-purpose transistor in a leadless DFN1006B-3 (SOT883B) package, rated for 50 V V_CEO, 100 mA I_C, and DC current gain (h_FE) of 120–270 at I_C = 1 mA. It serves as a compact switching and amplification device in space-constrained mobile power management circuits.

For engineers reviewing the 2PC4617QMB datasheet, 2PC4617QMB pinout, 2PC4617QMB application, or 2PC4617QMB equivalent, this page delivers verified package dimensions, thermal resistance (R_th(j-a) = 500 K/W on FR4), binary marking code (0000 1111), and AEC-Q101 qualification status - all critical for automotive-grade PCB layout and reliability validation.

Technical Context

This NPN transistor operates with open-base V_CEO up to 50 V and supports continuous collector current up to 100 mA, with peak pulse capability of 200 mA. Its low-profile 0.37 mm height and 1.0 × 0.6 mm footprint enable integration into ultra-thin mobile modules where SOT23-level power dissipation (590 mW with 1 cm² collector pad) is required in minimal board area.

The device exhibits V_CE(sat) ≤ 200 mV at I_C = 50 mA / I_B = 5 mA, f_T ≥ 100 MHz at V_CE = 12 V, and C_c = 1.5 pF at V_CB = 12 V - confirming suitability for medium-speed digital switching and RF-coupled biasing in portable audio and sensor interface stages.

FAQ

What is the maximum allowable junction temperature for 2PC4617QMB?

The absolute maximum junction temperature (T_j) is 150 °C, as defined in the Absolute Maximum Ratings table. Operation beyond this limit risks permanent degradation of h_FE and increased leakage currents. Thermal design must ensure T_j remains below 150 °C under worst-case ambient and power dissipation conditions, using R_th(j-a) = 500 K/W (free air) or 212 K/W (with 1 cm² collector pad) for calculation.

Is reflow soldering the only recommended assembly method?

Yes - the datasheet explicitly states "Reflow soldering is the only recommended soldering method" due to the DFN1006B-3 package's leadless construction and thermal sensitivity. Hand soldering or wave soldering is not supported and may cause delamination, voiding, or intermetallic failure. Reflow profiles must comply with JEDEC J-STD-020 moisture sensitivity level (MSL) requirements.

How does the binary marking code '0000 1111' identify 2PC4617QMB?

The 8-bit binary code '0000 1111' is laser-marked on the top surface of the DFN1006B-3 package and uniquely identifies the 2PC4617QMB variant per Nexperia's marking convention. It distinguishes QMB from RMB (0001 0000) and confirms the device belongs to the 2PC4617xMB family, enabling automated optical verification during SMT line setup and post-placement inspection.

Can 2PC4617QMB replace traditional SOT23 transistors in existing designs?

Direct replacement is feasible only with PCB layout revision: the DFN1006B-3 (1.0 × 0.6 mm) has different pad geometry, solder land pattern, and thermal pad requirements than SOT23 (2.9 × 1.3 mm). While electrical specs align (50 V, 100 mA), mechanical compatibility requires updated footprint, stencil design, and reflow profile validation - not a drop-in swap.
