onsemi MPS2369ARLRPG

Overview

MPS2369ARLRPG from onsemi is an NPN silicon switching transistor in TO-92 package, rated for V_CEO = 15 V, I_C = 200 mA, and P_D = 625 mW at T_A = 25°C. It delivers h_FE ≥ 40 at I_C = 10 mA/V_CE = 1.0 V, V_CE(sat) ≤ 0.25 V, and switching times (t_on/t_off/t_s) under 12/18/13 ns - used in low-voltage digital logic interface and signal switching circuits.

For engineers reviewing the MPS2369ARLRPG datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed V_CEO headroom, verified saturation voltage at 10 mA drive, thermal resistance (R_JA = 200°C/W), and documented switching performance at 100 MHz f_T.

Technical Context

This device operates as a general-purpose NPN bipolar junction transistor optimized for fast-switching applications with low V_CE(sat) and tight h_FE distribution. Its V_BRCES = 40 V and V_BREBO = 4.5 V define safe operating limits for base-emitter reverse bias and collector-emitter blocking in open-collector configurations.

The MPS2369ARLRPG supports DC and pulse operation up to 150°C junction temperature, with validated t_on ≤ 12 ns and t_off ≤ 18 ns under standardized test conditions (V_CC = 3.0 V, I_C = 10 mA). Its C_obo = 4.0 pF and f_T ≥ 100 MHz confirm suitability for high-speed digital switching below 10 MHz.

FAQ

What is the maximum continuous collector current rating for MPS2369ARLRPG?

The MPS2369ARLRPG has a maximum continuous collector current (I_C) of 200 mA at T_A = 25°C. Derating applies above 25°C at 5.0 mW/°C. This rating supports common low-power switching loads such as indicator LEDs, small relays, and logic buffers. Always verify actual junction temperature using R_JA = 200°C/W and measured power dissipation in the final design before deploying MPS2369ARLRPG.

Does MPS2369ARLRPG meet automotive-grade reliability requirements?

The MPS2369ARLRPG is not qualified to AEC-Q101 or other automotive reliability standards. Its specified operating junction temperature range is –55°C to +150°C, but onsemi does not publish automotive-specific qualification data (e.g., HTOL, ESD, or temperature cycling) for this part. For automotive applications, engineers should select onsemi's AEC-Q101-qualified NPN transistors instead of relying on the MPS2369ARLRPG.

What is the guaranteed minimum DC current gain (h_FE) for MPS2369ARLRPG at 10 mA collector current?

The MPS2369ARLRPG guarantees h_FE ≥ 40 at I_C = 10 mA and V_CE = 1.0 Vdc, per its official datasheet. This minimum value is tested and binned during production. At lower V_CE (e.g., 0.35 V), h_FE drops to ≥20. Designers must use the 40 minimum to ensure saturation with standard 1 mA base drive when implementing MPS2369ARLRPG in switching circuits.

Can MPS2369ARLRPG be used as a direct replacement for PN2222A in existing TO-92 designs?

Yes, the MPS2369ARLRPG shares the same TO-92 package and pinout (E-B-C) as PN2222A and can be used as a functional upgrade. However, it offers higher guaranteed h_FE (40 vs. 35), faster t_off (≤18 ns vs. ~25 ns), and lower V_CE(sat) (≤0.25 V vs. ≤0.3 V). No PCB changes are required, but verify base resistor values to maintain optimal saturation given the improved gain of MPS2369ARLRPG.

What is the thermal resistance (R_JA) of MPS2369ARLRPG and how does it affect power handling?

The MPS2369ARLRPG has a thermal resistance R_JA of 200°C/W, meaning junction temperature rises 200°C per watt dissipated in still air. At its rated 625 mW maximum power, this yields a 125°C rise above ambient - limiting practical continuous operation to ~250 mW at 75°C ambient. To sustain higher power, use PCB copper pour or forced airflow. This R_JA value directly constrains thermal design margins when applying MPS2369ARLRPG in enclosed or high-temperature environments.
