Product details

Overview

PN2222A,116 from STMicroelectronics is a silicon epitaxial planar NPN small-signal transistor in TO-92 package, rated for V_CEO = 40 V, I_C = 600 mA, P_tot = 500 mW, and h_FE ≥ 100 at I_C = 150 mA. It serves as a high-gain, low-V_CE(sat) load switch in TV and home appliance equipment.

For engineers reviewing the PN2222A,116 datasheet, PN2222A,116 pinout, PN2222A,116 application, or PN2222A,116 equivalent, key selection factors include saturation voltage under 150 mA drive, DC current gain stability across 0.1–500 mA, thermal resistance (R_thj-amb = 250 °C/W), and complementary pairing with PN2907A.

Technical Context

This NPN transistor operates in linear and switching modes with verified pulsed performance: t_s = 185–225 ns storage time and t_f = 24–60 ns fall time at I_C = 150 mA, V_CC = 30 V. Its f_T = 270 MHz supports RF preamplifier use up to VHF band.

Electrical behavior is defined by three breakdown voltages: V_(BR)CBO = 75 V, V_(BR)CEO = 40 V, and V_(BR)EBO = 6 V, with leakage currents (I_CEX, I_CB0) ≤ 10 nA at 25 °C and ≤ 1 µA at 150 °C junction temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	40 V - Maximum safe collector-emitter voltage with base open; defines upper rail limit in switching applications.
I_C	600 mA - Continuous collector current rating; supports relay drivers and medium-power LED loads.
V_CE(sat)	0.3 V (typ.) at I_C = 150 mA / I_B = 15 mA - Low conduction loss enables efficient low-voltage switching.
h_FE	100 (min.) at I_C = 150 mA - Ensures reliable base drive margin for saturated switch operation.
f_T	270 MHz - Enables use in VHF amplifiers and fast digital signal conditioning stages.
R_thj-amb	250 °C/W - Limits power dissipation to ≤200 mW at 70 °C ambient without heatsink.
C_CBO	4–8 pF - Low collector-base capacitance preserves bandwidth in amplifier configurations.

Pinout & Package

PN2222A,116 is housed in TO-92 through-hole package (JEDEC TO-92 variant), with standardized lead configuration: Emitter (pin 1), Base (pin 2), Collector (pin 3) when viewed with flat side facing user and leads downward.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Emitter	Current sink terminal; connects to ground or low-side return path in common-emitter switches.
Pin 2	Base	Control input; requires ~15 mA drive for full saturation at 150 mA collector load.
Pin 3	Collector	Current source terminal; ties to load and positive supply in low-side switch topology.

Key Features

Feature	Design Value
High DC current gain	h_FE ≥ 100 at I_C = 150 mA ensures robust saturation with minimal base drive overhead.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN small-signal transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
2N2222A (ON Semiconductor)	Identical absolute max ratings and electrical specs; minor h_FE binning variance (min 100 vs. min 75 in some variants).	No functional difference in switching or amplification roles; same TO-92 footprint and pinout.	Drop-in replacement where ON Semi's qualification or lot traceability is required.
BC547B (NXP)	Lower I_C (100 mA), lower V_CEO (45 V), higher h_FE (200–450), smaller SOT-23 package.	Suitable only for low-power signal switching; not recommended for >200 mA loads or relay driving.	Select BC547B only for space-constrained PCBs with sub-100 mA requirements and no thermal stress.

Compared with 2N2222A and BC547B, PN2222A,116 uniquely balances 600 mA current handling, 40 V breakdown, and TO-92 manufacturability-making it optimal for cost-sensitive, medium-power through-hole designs where thermal margin and legacy compatibility matter.

FAQ

What is the maximum continuous collector current for PN2222A,116?

The maximum continuous collector current (I_C) for PN2222A,116 is 600 mA at T_amb = 25 °C. Derating applies above 25 °C per R_thj-amb = 250 °C/W; at 70 °C ambient, usable I_C drops to approximately 200 mA to maintain T_j ≤ 150 °C. This rating is validated in the Absolute Maximum Ratings table of the official STMicroelectronics datasheet for PN2222A,116.

Is PN2222A,116 pin-compatible with the 2N2222A?

Yes, PN2222A,116 is pin-compatible with the industry-standard 2N2222A: both use TO-92 package with identical pinout (Emitter–Base–Collector on pins 1–2–3). Electrical specifications-including V_CEO, I_C, h_FE, and V_CE(sat)-are functionally identical per STMicroelectronics and ON Semiconductor datasheets. PN2222A,116 can replace 2N2222A in existing designs without layout changes.

What is the typical transition frequency (f_T) of PN2222A,116 and its design implication?

The typical transition frequency (f_T) of PN2222A,116 is 270 MHz at I_C = 20 mA, V_CE = 20 V. This enables stable small-signal amplification up to ~50 MHz with adequate gain margin and makes PN2222A,116 suitable for VHF preamplifiers, RF detector stages, and fast-switching digital buffers-applications confirmed in ST's application notes for PN2222A,116.

Does PN2222A,116 have a specified noise figure, and where is it relevant?

Yes, PN2222A,116 has a specified noise figure (NF) of 4 dB at I_C = 0.1 mA, V_CE = 10 V, f = 1 kHz, and ∆f = 200 Hz with R_G = 1 kΩ. This low-noise performance is critical in baseband analog signal paths such as TV video amplifiers and audio preamp stages, where PN2222A,116 maintains signal fidelity without introducing measurable degradation.

What is the complementary PNP transistor for PN2222A,116?

The complementary PNP transistor for PN2222A,116 is the PN2907A, also manufactured by STMicroelectronics. It shares matching voltage ratings (V_CEO = –60 V), current capability (I_C = –600 mA), and TO-92 packaging. This pairing is explicitly documented in the "PNP COMPLEMENTARY TYPE" section of the PN2222A,116 datasheet and supports balanced push-pull, phase-splitter, and H-bridge circuits using PN2222A,116.
