Diodes Incorporated DCX56-16-13

Overview

DCX56-16-13 from Diodes Incorporated is an NPN epitaxial planar silicon transistor in SOT89-3L package, rated for 80 V V_CEO, 1 A continuous collector current, and 1 W power dissipation at T_A = 25°C; it delivers h_FE = 100–250 at I_C = 150 mA, V_CE = 2.0 V, and is optimized for medium-power switching in DC-DC converters and linear regulators.

For engineers reviewing the DCX56-16-13 datasheet, DCX56-16-13 pinout, DCX56-16-13 application, or DCX56-16-13 equivalent, key selection criteria include verified V_CEO = 80 V rating, SOT89-3L thermal resistance (R_θJA = 125 °C/W), h_FE binning (−16 suffix), and RoHS-compliant matte tin plating on copper leadframe.

Technical Context

This discrete NPN bipolar junction transistor uses epitaxial planar die construction to ensure stable gain and low leakage across −55°C to +150°C operating range. Its SOT89-3L package provides enhanced thermal performance over SOT-23 while maintaining surface-mount compatibility for automated assembly.

It operates with V_BE(ON) ≤ 1.0 V at I_C = 500 mA and exhibits f_T = 200 MHz under 50 mA / 5 V conditions, supporting medium-frequency switching and analog amplification where moderate speed and robust saturation behavior are required.

FAQ

What is the meaning of the "−16" suffix in DCX56-16-13?

The "−16" suffix denotes the h_FE gain bin: devices are tested and binned to guarantee h_FE ≥ 100 and ≤ 250 at I_C = 150 mA and V_CE = 2.0 V. This ensures predictable base drive requirements in production designs and reduces variation in switching thresholds across batches.

Can DCX56-16-13 replace DCX56-13 in existing designs?

Yes - both share identical electrical specifications and SOT89-3L package. The "−13" and "−16" suffixes indicate different h_FE bins (−13: 63–250; −16: 100–250). Substitution is acceptable if the design does not rely on minimum h_FE < 100; verify base resistor values remain valid for guaranteed h_FE ≥ 100.

Is the exposed tab electrically isolated?

No - the metal tab (Pin 1) is internally connected to the collector terminal. It must be electrically isolated from other circuit nodes unless intentionally used as the collector node. Thermal anchoring to a large copper pour is recommended to meet R_θJA = 125 °C/W specification.

Does DCX56-16-13 support lead-free reflow profiles?

Yes - it features matte tin annealed over copper leadframe, qualified per J-STD-020C Level 1 moisture sensitivity, and meets MIL-STD-202 Method 208 solderability requirements. Standard Pb-free reflow profiles (peak 260°C, 10 sec max) are fully supported without degradation.
