Product details

Overview

MPS2222ARLRMG 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 DC current gain (h_FE) of 100–300 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 MPS2222ARLRMG datasheet, pinout, applications, or equivalent options, key selection criteria include V_CEO/V_CBO ratings, h_FE consistency across temperature, saturation voltage at I_C/I_B = 10, and Pb-free TO-92 tape-and-reel packaging compliance.

Technical Context

The MPS2222ARLRMG is a discrete NPN bipolar junction transistor optimized for linear amplification and medium-speed switching. Its design emphasizes stable h_FE over −55°C to +150°C, low leakage (I_CEO ≤ 10 nA), and predictable V_CE(sat) ≤ 0.3 V at I_C = 150 mA, I_B = 15 mA.

It features f_T = 300 MHz at I_C = 20 mA, V_CE = 20 V, enabling RF amplifier stages up to VHF; C_obo = 8.0 pF and C_ibo = 25 pF support bandwidth-limited bias networks. Thermal resistance R_JA = 200°C/W confirms suitability for ambient-limited through-hole designs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	40 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V logic-level switching and 36 V supply rails.
I_C Continuous	600 mA - Sustained load drive capability; supports relay coils, LED arrays, and small solenoids without forced cooling.
h_FE @ 10 mA	100–300 - High and consistent DC current gain ensures reliable base drive sizing and reduces base resistor tolerance sensitivity.
V_CE(sat) @ 150 mA	0.3 V - Low saturation voltage minimizes power loss (P_sat ≈ 45 mW) and thermal rise in switching mode.
f_T	300 MHz - Enables stable small-signal amplification up to ~100 MHz with adequate gain margin; suitable for IF stages and oscillator buffers.
R_JA	200°C/W - Predictable junction-to-ambient thermal path allows accurate derating to 5.0 mW/°C above 25°C in open-air PCB layouts.

Pinout & Package

Package: TO-92 (Case 29-11), Pb-free, straight-lead or bent-lead configuration per tape-and-reel orientation. Dimensions: 4.45 × 4.32 × 3.18 mm (L × W × H), with 2.54 mm lead pitch.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current sink terminal	Connected to ground or low-side return path; requires low-impedance trace for stable bias and minimal V_EB error.
2 (Base)	Control input node	Receives current-limited drive; base resistor must be sized for target I_B = I_C/h_FE(min) to ensure saturation.
3 (Collector)	Current source terminal	Connected to load and positive rail; layout must minimize inductance to suppress switching overshoot during turn-off.

Key Features

Feature	Design Value
Pb-free TO-92 packaging	Complies with RoHS Directive 2011/65/EU and JEDEC J-STD-020 reflow profiles; eliminates lead-based solder compatibility concerns.
High V_CBO = 75 V	Supports inductive load flyback clamping without snubber redesign; extends safe operating area during transient voltage spikes.
Low I_CEO ≤ 10 nA	Enables ultra-low standby current in battery-powered sensor interfaces and sleep-mode control circuits.
Guaranteed h_FE ≥ 100 @ −55°C	Ensures functional gain stability in automotive under-hood and industrial outdoor environments without gain compensation.
Switching t_s ≤ 225 ns	Permits PWM operation up to ~2 MHz with <1% duty-cycle distortion; suitable for DC-DC converter gate drivers and motor commutation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN general-purpose transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
PN2222A	V_CEO = 40 V, h_FE min = 100, but C_ibo = 30 pF (vs. 25 pF) and f_T = 250 MHz (vs. 300 MHz); not Pb-free certified.	Suitable for cost-sensitive non-RoHS legacy designs; slightly lower bandwidth limits VHF-stage use.	Select PN2222A only if Pb-free compliance is not required and f_T margin > 50 MHz is unnecessary.
MMBT2222ALT1G	SOT-23 surface-mount package; identical electrical specs but R_JA = 300°C/W and max I_C = 600 mA derated to 300 mA at T_A > 70°C.	Designed for space-constrained PCBs; requires thermal pad and layout optimization for same power handling.	Choose MMBT2222ALT1G when board area is critical and reflow-compatible assembly is available.

Compared with PN2222A and MMBT2222ALT1G, the MPS2222ARLRMG offers superior high-frequency performance and guaranteed Pb-free compliance in through-hole TO-92, making it optimal for new industrial control and automotive body electronics where reliability, thermal predictability, and regulatory alignment are prioritized.

FAQ

What is the maximum junction temperature rating for the MPS2222ARLRMG?

The MPS2222ARLRMG has a specified operating and storage junction temperature range of −55°C to +150°C. This wide range supports deployment in under-hood automotive modules, industrial motor controls, and outdoor power supplies where ambient temperatures exceed 85°C. Derating of power dissipation begins above 25°C at 5.0 mW/°C.

Does the MPS2222ARLRMG meet RoHS requirements?

Yes, the MPS2222ARLRMG is explicitly marked as Pb-free in the ordering information and conforms to RoHS Directive 2011/65/EU. Its TO-92 package uses lead-free terminations and complies with JEDEC J-STD-020 moisture sensitivity and reflow profile standards.

What is the typical noise figure of the MPS2222ARLRMG and at what conditions is it measured?

The MPS2222ARLRMG has a maximum noise figure (NF) of 4.0 dB, measured at I_C = 100 µA, V_CE = 10 V, R_S = 1.0 kΩ, and f = 1.0 kHz. This low-noise performance makes it suitable for microphone preamplifiers and sensor signal conditioning where signal integrity is critical.

Yes, the MPS2222ARLRMG supports switching applications with documented parameters: t_d ≤ 10 ns, t_r ≤ 25 ns, t_s ≤ 225 ns, and t_f ≤ 60 ns at I_C = 150 mA. Its 300 MHz f_T and low V_CE(sat) enable efficient operation in low-power DC-DC converters and PWM-driven loads up to ~2 MHz.

How does the h_FE of the MPS2222ARLRMG vary with temperature and collector current?

The MPS2222ARLRMG maintains h_FE ≥ 100 at I_C = 10 mA, V_CE = 10 V, and T_J = −55°C, and h_FE reaches 300 at the same bias at 25°C. At I_C = 500 mA, h_FE drops to ≥ 30, confirming its suitability for both small-signal amplification and medium-current switching with appropriate base drive scaling.
