Product details

Overview

MPS2369ARLRP from onsemi is an NPN silicon switching transistor in TO-92 package, rated for V_CEO = 15 V, I_C = 200 mA, and P_D = 625 mW at T_A = 25°C, with h_FE ≥ 40 (I_C = 10 mA, V_CE = 1.0 V), used in low-voltage digital logic interface and signal switching applications.

For engineers reviewing the MPS2369ARLRP datasheet, pinout, applications, or equivalent options, key selection criteria include saturation voltage (V_CE(sat) ≤ 0.25 V at I_C = 10 mA/I_B = 1 mA), fast switching (t_on ≤ 12 ns, t_off ≤ 18 ns), thermal resistance (R_JA = 200°C/W), and ESD-safe handling per JEDEC JESD22-A114.

Technical Context

The MPS2369ARLRP operates as a general-purpose NPN bipolar junction transistor optimized for saturated-switching operation in DC–100 MHz small-signal circuits. Its design emphasizes low V_CE(sat), high h_FE consistency across temperature (–55°C to +150°C), and tight parameter distribution for reliable digital gate driving and load control.

It features a TO-92 (CASE 29–11) through-hole package with emitter-base-collector pinout (Pin 1 = E, Pin 2 = B, Pin 3 = C), validated for use in 3.3 V/5 V logic-level interfacing where base drive current ≤ 10 mA and collector load ≤ 200 mA are required.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	15 V - Maximum safe collector-emitter voltage under open-base conditions; defines upper rail limit in 3.3 V/5 V logic systems.
I_C (cont.)	200 mA - Continuous collector current capability; supports driving LEDs, relays, or small MOSFET gates without external heat sinking.
V_CE(sat)	≤ 0.25 V @ I_C/I_B = 10 mA/1 mA - Ensures minimal power loss and voltage drop in saturated switch mode.
h_FE	40–120 @ I_C = 10 mA, V_CE = 1.0 V - Provides predictable base current sizing for robust turn-on margin in TTL/CMOS-driven stages.
t_off	≤ 18 ns @ V_CC = 3.0 V, I_C = 10 mA - Enables clean switching up to ~20 MHz square-wave signals in timing and pulse generation.
R_JA	200°C/W - Specifies thermal derating of 5.0 mW/°C above 25°C ambient; requires PCB copper area or airflow for >100 mW sustained dissipation.

Pinout & Package

Package: TO-92 (CASE 29–11), through-hole, epoxy-molded plastic body with 3 leads. Dimensions conform to JEDEC TO-226AA standard (A = 4.45–5.20 mm, B = 4.32–5.33 mm, C = 3.18–4.19 mm).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Emitter)	Current sink terminal	Connected to ground or low-side return path; sets reference for base-emitter bias and collector current flow direction.
Pin 2 (Base)	Control input	Receives TTL/CMOS-compatible drive (0.7–1.6 V V_BE(sat)) to enable conduction; requires series resistor for current limiting.
Pin 3 (Collector)	Current source terminal	Connected to load (e.g., LED anode, relay coil) and positive supply; carries full switched load current up to 200 mA.

Key Features

Feature	Design Value
Low saturation voltage	V_CE(sat) ≤ 0.25 V ensures <1.5 mW conduction loss at 10 mA load, critical for battery-powered logic interfaces.
High DC current gain	h_FE ≥ 40 at I_C = 10 mA enables single-stage CMOS output (I_OH/I_OL ≤ 20 mA) to directly drive the base without amplification.
Fast switching speed	t_on/t_off ≤ 12/18 ns allows clean edge transitions in clock buffering, pulse shaping, and PWM dimming circuits.
Wide operating temperature	Junction range –55°C to +150°C supports deployment in automotive engine compartments and industrial control enclosures.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN switching transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC337-40	V_CEO = 45 V, h_FE = 250–630, R_JA = 200°C/W, same TO-92 package	Higher voltage headroom but wider h_FE spread; less suitable for precision base-current-limited designs	Prefer when higher V_CEO margin is needed and gain variation is acceptable.
PN2222A	V_CEO = 30 V, I_C = 600 mA, V_CE(sat) = 0.3 V @ 150 mA/15 mA, TO-92	Higher current capacity but 20% higher saturation voltage; larger base drive requirement	Choose when driving >200 mA loads or when legacy PN2222A footprint compatibility is mandatory.

Compared with BC337-40 and PN2222A, the MPS2369ARLRP offers tighter h_FE control (40–120 vs. 250–630 or 100–300), lower V_CE(sat) at low I_B, and optimized switching speed for 3.3 V logic interfacing-making it preferred for space-constrained, low-power digital switching where gain predictability matters.

FAQ

What is the maximum continuous collector current rating for MPS2369ARLRP?

The MPS2369ARLRP has a maximum continuous collector current (I_C) rating of 200 mA at T_A = 25°C. Derating applies above 25°C at 5.0 mW/°C, and actual usable current depends on PCB thermal design and ambient temperature. For sustained 200 mA operation, ensure junction temperature remains below 150°C using adequate copper pour or forced air cooling.

Does MPS2369ARLRP support operation at elevated temperatures like +125°C?

Yes, the MPS2369ARLRP is qualified for operation from –55°C to +150°C junction temperature. At +125°C ambient, its V_CE(sat) increases to ≤ 0.30 V and h_FE drops to ≥ 20 (I_C = 10 mA, V_CE = 1.0 V), maintaining functional switching behavior in automotive under-hood or industrial motor-control environments.

What is the pin configuration of MPS2369ARLRP in the TO-92 package?

The MPS2369ARLRP uses standard TO-92 pinout: Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector (viewed with flat side facing outward and leads pointing down). This matches JEDEC TO-226AA mechanical specification and is identical to BC547, PN2222A, and MPS2222A footprints.

How does the switching speed of MPS2369ARLRP compare to standard general-purpose transistors?

The MPS2369ARLRP delivers t_on ≤ 12 ns and t_off ≤ 18 ns under specified test conditions (V_CC = 3.0 V, I_C = 10 mA), outperforming legacy parts like PN2222A (t_off ≈ 250 ns). This enables reliable operation up to 20 MHz in pulse applications, making MPS2369ARLRP suitable for high-speed digital interfacing where timing integrity is critical.

Is MPS2369ARLRP suitable for driving inductive loads such as relays or solenoids?

Yes, the MPS2369ARLRP can safely drive inductive loads up to 200 mA, provided an external flyback diode (e.g., 1N4148) is placed across the coil to clamp inductive kickback. Its V_CES = 40 V rating provides sufficient margin against voltage spikes, and its 625 mW power dissipation accommodates typical relay hold currents without thermal runaway.
