onsemi MPS2222ARLRP

Overview

MPS2222ARLRP from onsemi is an NPN silicon general-purpose transistor in TO-92 package, rated for 40 V_CEO, 600 mA continuous collector current, and 1.5 W total dissipation at T_C = 25°C; it delivers h_FE ≥ 100 at I_C = 10 mA and supports switching applications with t_r ≤ 25 ns and t_f ≤ 60 ns.

For engineers reviewing the MPS2222ARLRP datasheet, pinout, applications, or equivalent options, key selection criteria include V_CEO/V_CBO margin, saturation voltage at target I_C/I_B, thermal resistance (R_θJC = 83.3°C/W), and small-signal f_T = 300 MHz performance.

Technical Context

This device operates as a medium-speed, medium-current NPN bipolar junction transistor optimized for linear amplification and switching in low-voltage DC circuits. Its design supports stable h_FE across –55°C to +150°C junction temperature and exhibits low leakage: I_CBO ≤ 0.01 µA and I_CEX ≤ 10 nA at rated conditions.

The MPS2222ARLRP features defined switching timing (t_d ≤ 10 ns, t_s ≤ 225 ns) under standardized test conditions (V_CC = 30 V, I_C = 150 mA, I_B1 = I_B2 = 15 mA), and its small-signal parameters-h_ie = 0.25–1.25 kΩ, h_fe = 75–375, C_obo ≤ 8.0 pF-are specified at 1 kHz and 100 MHz respectively.

FAQ

What is the maximum continuous collector current rating for MPS2222ARLRP?

The MPS2222ARLRP has a maximum continuous collector current (I_C) rating of 600 mAdc at T_A = 25°C. Derating applies above 25°C per 5.0 mW/°C ambient or 12 mW/°C case temperature. This rating supports robust operation in relay drivers and LED array sinks without forced cooling.

Does MPS2222ARLRP have a guaranteed minimum DC current gain (h_FE)?

Yes, the MPS2222ARLRP guarantees h_FE ≥ 100 at I_C = 10 mAdc and V_CE = 10 Vdc, per the official onsemi datasheet. This minimum is confirmed across the full operating temperature range (–55°C to +150°C), enabling reliable bias network design in production hardware.

What is the thermal resistance from junction to case (R_θJC) for MPS2222ARLRP?

The MPS2222ARLRP has a thermal resistance R_θJC of 83.3°C/W, measured at T_C = 25°C. This value reflects efficient heat transfer from the silicon die to the TO-92 case, allowing up to 1.5 W dissipation with appropriate heatsinking-critical for sustained PWM or linear-mode operation.

Is MPS2222ARLRP suitable for high-frequency switching applications?

Yes, the MPS2222ARLRP supports high-frequency switching with t_r ≤ 25 ns and t_f ≤ 60 ns under standard test conditions, and f_T = 300 MHz. These characteristics make it suitable for PWM motor control up to 20 kHz and RF predriver stages below 100 MHz, provided layout minimizes parasitic inductance.

What is the pin configuration for MPS2222ARLRP in the TO-92 package?

The MPS2222ARLRP uses TO-92 Style 1 pinout: Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector. This configuration is documented in the onsemi datasheet (MPS2222/D, Rev. 1, page 7) and must be verified during PCB layout to prevent functional failure due to reversed connections.
