Product details
Overview
MPS2222RLRAG from onsemi is an NPN silicon general-purpose transistor in TO-92 package, rated for 40 VCEO, 600 mA continuous collector current, and 625 mW power dissipation at TA = 25°C. It delivers DC current gain (hFE) of 100–300 at IC = 10 mA, VCE = 10 V, and supports switching applications with td ≤ 10 ns, tr ≤ 25 ns, and ts ≤ 225 ns.
For engineers reviewing the MPS2222RLRAG datasheet, pinout, applications, or equivalent options, this page provides verified electrical specs, thermal behavior, switching timing data, TO-92 terminal mapping, and validated alternative transistors for low-voltage amplification and digital switching designs.
Technical Context
This device operates as a discrete NPN bipolar junction transistor optimized for linear amplification and saturated-switching roles in low-power analog and digital circuits. Its fT of 300 MHz enables RF-capable small-signal amplification up to VHF bands, while its low VCE(sat) (0.3 V at IC = 150 mA, IB = 15 mA) ensures efficient on-state conduction in logic-level driven switches.
The MPS2222RLRAG shares identical electrical characteristics and pinout with the MPS2222A variant, including V(BR)CEO = 40 V, V(BR)CBO = 75 V, and ICBO ≤ 0.01 µA - confirming its suitability for noise-sensitive preamplifier stages and robust industrial control I/O buffering where leakage and breakdown margin are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 40 V - Maximum safe collector-emitter voltage before avalanche breakdown; enables use in 24 V rail systems with margin. |
| IC Continuous | 600 mA - Sustained collector current handling without thermal runaway at 25°C ambient; supports relay drivers and LED arrays. |
| hFE @ 10 mA | 100–300 - Predictable DC current gain range for stable bias design in Class-A amplifiers and emitter-follower buffers. |
| VCE(sat) | 0.3 V @ IC/IB = 10 - Low saturation voltage minimizes power loss and self-heating in switching mode. |
| fT | 300 MHz - Unity-gain frequency confirms usable bandwidth for 10–50 MHz signal amplification and oscillator stages. |
| RJA | 200 °C/W - Thermal resistance from junction to ambient defines heatsinking requirements for sustained 500 mW operation. |
| ts (Storage) | ≤ 225 ns - Critical storage time parameter limiting maximum switching frequency in saturated logic interfaces. |
Pinout & Package
Package: TO-92 (Case 29-11), Pb-free, straight or bent lead options; 4.45 × 5.20 × 4.19 mm body with 2.54 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current sink terminal | Reference node for base bias network; connects to ground or low-impedance return path in common-emitter configurations. |
| 2 (Base) | Control input | Receives current-limited drive to modulate collector current; requires series resistor to limit IB and prevent overdrive. |
| 3 (Collector) | Current source terminal | Connects to load (e.g., relay coil, LED anode); must be decoupled from supply when used in switching to suppress inductive kickback. |
Key Features
| Feature | Design Value |
|---|---|
| Pb-free TO-92 packaging | Complies with RoHS Directive 2011/65/EU; eliminates lead contamination risk in reflow soldering and end-of-life recycling. |
| Low VCE(sat) at high IC | 0.3 V at IC = 150 mA ensures <100 mW conduction loss per switch event, reducing thermal stress in high-duty-cycle drivers. |
| High fT and low Cobo | 300 MHz fT and 8 pF output capacitance enable stable small-signal amplification up to 30 MHz without peaking or instability. |
| Wide TJ range | −55°C to +150°C junction operation supports deployment in automotive under-hood modules and industrial PLC I/O cards. |
| Low leakage ICBO | ≤ 0.01 µA at 50 V ensures minimal standby current in battery-powered sensor nodes and always-on interface circuits. |
Applications
| LED Driver Circuit | Microcontroller GPIO Expander |
|---|---|
|
Use Scenario: Driving 20 mA indicator LEDs from 3.3 V or 5 V MCU outputs via single-transistor switch. IC Role / Device Role / Timing Role: NPN switch operating in saturation region; acts as current-controlled current source between VCC and LED cathode. Use Value: VCE(sat) ≤ 0.3 V ensures >95% LED forward voltage utilization; hFE ≥ 100 allows 200 µA base drive to switch 20 mA load reliably. |
Use Scenario: Extending limited GPIO count of ARM Cortex-M0+ microcontrollers to control external relays or solenoids. IC Role / Device Role / Timing Role: Digital interface buffer providing level-shifted, current-amplified output for 12 V/24 V loads. Use Value: ts ≤ 225 ns and tf ≤ 60 ns support 10 kHz PWM control of inductive loads without shoot-through or excessive switching loss. |
| Audio Preamp Stage | Industrial Sensor Signal Conditioning |
|
Use Scenario: First-stage low-noise amplification of electret microphone output (1–10 mV AC) into ADC input of audio codec IC. IC Role / Device Role / Timing Role: Common-emitter amplifier biased at IC = 1 mA; provides 20–30 dB voltage gain with minimal distortion. Use Value: NF ≤ 4.0 dB at 1 kHz and IC = 100 µA ensures clean signal capture; hie = 2.0 kΩ matches typical mic impedance for optimal power transfer. |
Use Scenario: Converting 4–20 mA current-loop sensor outputs to 0–3.3 V analog signals for industrial PLC analog inputs. IC Role / Device Role / Timing Role: Transimpedance amplifier configured with emitter-degeneration resistor for linear I/V conversion. Use Value: hFE stability across −55°C to +125°C ensures ±0.5% full-scale error drift; V(BR)CEO = 40 V withstands transient surges on factory floor wiring. |
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 VCEO (40 V), IC (600 mA), and TO-92 package; hFE min = 100 at IC = 10 mA but no guaranteed fT spec. | Lacks published fT and switching time data; suitable only for DC/low-frequency (<1 MHz) amplification and switching. | Select PN2222A only when RF performance or precise timing is not required; verify hFE binning if gain consistency is critical. |
| BC547B | VCEO = 45 V, IC = 100 mA, hFE = 200–450 at IC = 2 mA; smaller TO-92 footprint but lower current rating. | Not suitable for 500 mA loads; preferred in space-constrained PCBs where gain linearity at low IC matters more than power handling. | Choose BC547B for compact low-current signal paths; avoid in relay/solenoid driver roles due to 100 mA IC limit. |
Compared with PN2222A and BC547B, the MPS2222RLRAG uniquely combines 600 mA current capability, 300 MHz fT, and documented nanosecond-scale switching times - making it the only option among the three qualified for both high-current digital interfacing and VHF small-signal amplification in a single TO-92 device.

FAQ
What is the maximum continuous collector current rating for the MPS2222RLRAG?
The MPS2222RLRAG is rated for 600 mA continuous collector current at TA = 25°C. Derating applies above 25°C at 5.0 mW/°C for ambient operation or 12 mW/°C when mounted on a heatsink (TC = 25°C). This rating supports driving small relays, LED arrays, and logic-level loads without forced cooling in most applications.
Does the MPS2222RLRAG have a specified current-gain bandwidth product (fT)?
Yes, the MPS2222RLRAG has a guaranteed minimum fT of 300 MHz at IC = 20 mA, VCE = 20 V, and f = 100 MHz. This value is confirmed in the official onsemi datasheet and enables reliable use in VHF amplifiers, crystal oscillator buffers, and RF detector stages up to 30 MHz.
Is the MPS2222RLRAG pin-compatible with the original 2N2222 transistor?
No - the MPS2222RLRAG follows the standard TO-92 pinout (Emitter-Base-Collector on pins 1-2-3), matching the 2N2222A and PN2222A, but differs from early 2N2222 variants that used Collector-Base-Emitter ordering. Always verify pinout using the onsemi marking diagram: "MPS2222" with pin 1 marked by dot or notch orientation.
What is the thermal resistance junction-to-ambient (RJA) for the MPS2222RLRAG in free air?
The MPS2222RLRAG has a maximum RJA of 200°C/W when mounted in still air on a standard FR-4 PCB with no copper pour. This means a 625 mW power dissipation will raise the junction temperature by 125°C above ambient - requiring derating or heatsinking for continuous operation above 25°C ambient.
Can the MPS2222RLRAG be used in linear amplifier configurations?
Yes, the MPS2222RLRAG supports linear operation with hFE = 100–300 at IC = 10 mA and VCE = 10 V, and exhibits low noise figure (NF ≤ 4.0 dB) at 1 kHz. Its hie = 2.0 kΩ and hfe = 300 at 10 mA make it well-suited for common-emitter preamplifiers, emitter followers, and active filters in audio and sensor signal chains.
