Product details

Overview

MPS2222RLRPG 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 MPS2222RLRPG datasheet, pinout, applications, or equivalent options, this discrete NPN transistor is selected for low-voltage switching, signal amplification, and interface-level logic translation in industrial controls, consumer power supplies, and embedded sensor conditioning circuits.

Technical Context

The MPS2222RLRPG operates as a standard bipolar junction transistor with fixed-emitter configuration and base-controlled current amplification. Its electrical behavior is defined by h_FE ≥ 100 at I_C = 10 mA, V_CE = 10 V, and V_CE(sat) ≤ 0.3 V at I_C = 150 mA, I_B = 15 mA - confirming suitability for saturated-switch operation.

Thermal performance is characterized by R_JA = 200°C/W and R_JC = 83.3°C/W, enabling reliable operation across −55°C to +150°C junction temperature range. Small-signal parameters include f_T = 300 MHz and C_ibo = 25 pF, supporting moderate-frequency amplification up to ~100 MHz.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	40 V - Maximum safe collector-emitter voltage before breakdown under open-base condition.
I_C (continuous)	600 mA - Sustained collector current capability without thermal derating at 25°C ambient.
P_D @ T_A = 25°C	625 mW - Power dissipation limit with free-air convection cooling; requires heatsinking above 25°C.
h_FE (min)	100 - Minimum DC current gain at I_C = 10 mA, V_CE = 10 V, ensuring predictable base drive sizing.
V_CE(sat)	0.3 V - Collector-emitter saturation voltage at I_C = 150 mA, I_B = 15 mA; enables low-loss switching.
f_T	300 MHz - Transition frequency where small-signal current gain drops to unity; supports RF amplifier use up to ~100 MHz.
R_JA	200°C/W - Junction-to-ambient thermal resistance; defines required PCB copper area for thermal management.

Pinout & Package

Package: TO-92 (Case 29-11), Pb-free, straight or bent lead options; 3-pin through-hole plastic package with standardized pin 1 = Emitter, pin 2 = Base, pin 3 = Collector.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current exit path for majority carriers	Connected to ground or low-side reference; base-emitter junction forward-biased during turn-on.
2 (Base)	Control terminal for minority carrier injection	Receives current-limited drive (e.g., via 1–10 kΩ resistor) to regulate collector current linearly or switchfully.
3 (Collector)	Current entry path for majority carriers	Connected to load and supply rail; sustains up to 40 V and 600 mA in active/saturated modes.

Key Features

Feature	Design Value
Pb-free TO-92 packaging	Complies with RoHS Directive 2011/65/EU; compatible with lead-free reflow and wave soldering processes.
High V_CEO rating	40 V enables use in 24 V industrial bus interfaces and 36 V automotive auxiliary circuits without derating.
Low V_CE(sat)	0.3 V at I_C/I_B = 10 reduces conduction loss in relay drivers and LED switches.
Guaranteed h_FE range	100–300 at I_C = 10 mA ensures consistent biasing across production lots without trim resistors.
Fast switching times	t_s ≤ 225 ns allows >100 kHz PWM control in DC-DC feedback paths and motor gate drivers.

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	Same V_CEO = 40 V, I_C = 600 mA, but h_FE min = 100 only at I_C = 150 mA (not 10 mA); higher V_CE(sat) = 0.4 V.	Less suitable for low-current switching; marginally higher conduction loss in battery-powered designs.	Select PN2222A only if legacy design compatibility or dual-source qualification is required.
MMBT2222ALT1G	SMT version in SOT-23; identical electrical specs but 200 mW P_D @ T_A; requires PCB layout change.	Not usable in through-hole prototypes or high-power (>200 mW) linear operation without derating.	Choose MMBT2222ALT1G for space-constrained PCBs where thermal management permits lower power handling.

Compared with PN2222A and MMBT2222ALT1G, the MPS2222RLRPG offers superior h_FE consistency at low I_C, lower V_CE(sat), and through-hole manufacturability - making it optimal for cost-sensitive, medium-power discrete switching where layout flexibility and thermal margin matter.

FAQ

What is the maximum operating temperature for the MPS2222RLRPG?

The MPS2222RLRPG has a specified junction temperature range of −55°C to +150°C. Its thermal resistance R_JA is 200°C/W, so sustained operation at full 600 mA requires careful PCB thermal design or ambient derating above 25°C to avoid exceeding 150°C junction temperature.

Is the MPS2222RLRPG RoHS-compliant and lead-free?

Yes, the MPS2222RLRPG 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 level (MSL) requirements for standard assembly processes.

How does the MPS2222RLRPG differ from the MPS2222 (non-A) variant?

The MPS2222RLRPG corresponds to the MPS2222A version, not the base MPS2222. Key differences include higher V_CEO (40 V vs. 30 V), higher V_CBO (75 V vs. 60 V), lower V_CE(sat) (0.3 V vs. 0.4 V), and guaranteed h_FE ≥ 100 at I_C = 10 mA - making MPS2222RLRPG the preferred choice per onsemi documentation.

Can the MPS2222RLRPG be used in linear amplifier configurations?

Yes, the MPS2222RLRPG supports linear operation with h_fe = 300 at I_C = 10 mA and f = 1 kHz, and input impedance h_ie = 8.0 kΩ. However, its f_T = 300 MHz and noise figure ≤ 4.0 dB make it suitable only for audio- and low-MHz-bandwidth amplifiers - not RF or precision op-amp replacement.

What is the pin configuration for the MPS2222RLRPG in TO-92 package?

The MPS2222RLRPG uses standard TO-92 pinout: Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector - confirmed by onsemi's marking diagram and package outline (Case 29-11). This matches industry-standard 2N2222A orientation and enables direct footprint reuse in legacy designs.
