FAQ

What is the maximum continuous collector current for PHPT61010PYX?

The maximum continuous collector current (I_C) is −10 A at T_amb = 25 °C with proper PCB copper area (6 cm² collector pad on FR4). Derating applies above 25 °C per Fig. 1; at 100 °C ambient, usable I_C drops to approximately −6.5 A due to thermal limits.

Is PHPT61010PYX suitable for linear-mode operation?

Yes-its stable h_FE (10–15 at −10 A), low V_CE(sat) (−530 mV typ.), and 175 °C T_j(max) make it suitable for linear regulators and constant-current sources. Thermal design must ensure junction temperature remains within limit under worst-case power dissipation.

How does the LFPAK56 package improve thermal performance over DPAK?

The LFPAK56 package reduces thermal resistance to mounting base (R_th(j-mb) = 6 K/W) versus typical DPAK (~12–15 K/W) via a larger, fully exposed copper collector pad and shorter internal thermal paths. This yields ~50 % lower junction-to-PCB temperature rise at same power.

Does PHPT61010PYX require a base resistor, and what value is recommended?

Yes-a base resistor is required to limit base current. For −10 A collector current and h_FE = 12 (min), minimum I_B = −0.83 A. With V_BE(sat) ≈ −1.3 V and drive voltage of −5 V, R_B ≈ 4.5 Ω (2 W pulse-rated). Actual value depends on drive source capability and switching speed requirements.
