onsemi MPS2222ARLRAG

Overview

MPS2222ARLRAG from onsemi is an NPN silicon general-purpose transistor in TO-92 package, rated for 40 V_CEO, 600 mA continuous collector current, and 625 mW power dissipation at T_A = 25°C; it delivers h_FE ≥ 100 at I_C = 10 mA, V_CE = 10 V, and supports switching applications with t_d ≤ 10 ns, t_r ≤ 25 ns, and t_s ≤ 225 ns.

For engineers reviewing the MPS2222ARLRAG datasheet, pinout, applications, or equivalent options, this part serves as a Pb-free, tape-and-reel packaged variant of the MPS2222A family optimized for cost-sensitive linear amplification and medium-speed switching in consumer and industrial control circuits.

Technical Context

The MPS2222ARLRAG operates as a discrete NPN bipolar junction transistor with fixed emitter-base and collector-base junction structures, supporting both analog amplification (via h_FE = 100–300) and digital switching (with V_CE(sat) = 0.3 V at I_C = 150 mA, I_B = 15 mA). Its f_T = 300 MHz enables RF-capable small-signal gain up to ~100 MHz.

Thermal design relies on R_JA = 200°C/W (ambient) and R_JC = 83.3°C/W (case), with operating junction temperature spanning −55°C to +150°C. Cutoff leakage is tightly controlled: I_CEX ≤ 10 nA at V_CE = 60 V and I_CBO ≤ 0.01 μA at V_CB = 50 V.

FAQ

What is the maximum collector-emitter voltage rating for MPS2222ARLRAG?

The MPS2222ARLRAG has a guaranteed V_CEO rating of 40 Vdc, verified per onsemi's datasheet Rev. 3 (2007). This exceeds the 30 V rating of the standard MPS2222 and allows safe operation in 36 V nominal systems with transient margin. The device must not be operated beyond this limit to avoid junction breakdown.

Is MPS2222ARLRAG pin-compatible with the original 2N2222A?

Yes, MPS2222ARLRAG uses the same TO-92 package with identical E-B-C pinout (Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector) as 2N2222A. It is a direct physical and electrical replacement with improved V_CEO (40 V vs. 30 V) and higher minimum h_FE (100 vs. 75), requiring no PCB changes.

What is the typical DC current gain (h_FE) of MPS2222ARLRAG at 10 mA collector current?

The MPS2222ARLRAG guarantees h_FE ≥ 100 at I_C = 10 mA, V_CE = 10 V, and T_A = 25°C, with typical values reaching 300. This is confirmed in the "ON CHARACTERISTICS" table of the official datasheet and supports stable biasing in amplifier and switch driver circuits without gain-dependent instability.

Does MPS2222ARLRAG support high-frequency signal amplification?

Yes, the MPS2222ARLRAG has an f_T of 300 MHz, enabling effective small-signal amplification up to ~100 MHz. Its C_ibo = 25 pF and C_obo = 8.0 pF contribute to stable high-frequency response, making it suitable for RF detector stages, oscillator active devices, and broadband preamplifiers within its voltage and current limits.

What packaging format does MPS2222ARLRAG ship in, and is it RoHS-compliant?

MPS2222ARLRAG ships in Pb-free TO-92 tape-and-reel format (2000 units per reel), explicitly marked "G" in the ordering code and certified RoHS-compliant per EU Directive 2011/65/EU. The "R" denotes tape-and-reel, "L" indicates low-profile lead form, and "AG" confirms Pb-free finish and packaging.
