Product details

Overview

MPS2369AG 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. It delivers h_FE ≥ 40 at I_C = 10 mA/V_CE = 1.0 V, V_CE(sat) ≤ 0.25 V, and t_off ≤ 18 ns - enabling fast, low-loss switching in compact DC-DC bias networks and digital logic interfaces.

For engineers reviewing the MPS2369AG datasheet, pinout, applications, or equivalent options, key selection criteria include verified V_CEO/I_C derating behavior, guaranteed h_FE minimum at low V_CE, saturation voltage stability across –55°C to +125°C, and TO-92 thermal resistance (R_JA = 200°C/W) for board-level power density planning.

Technical Context

This discrete NPN transistor operates as a saturated switch in low-voltage, medium-speed digital and analog control paths. Its design emphasizes rapid turn-on/turn-off (t_on ≤ 12 ns, t_off ≤ 18 ns) with low base drive requirements (I_B = 1 mA for 10 mA I_C) and tight V_BE(sat) control (0.7–1.6 V range).

It supports operation from –55°C to +150°C junction temperature, with validated breakdown margins: V_(BR)CES = 40 V, V_(BR)CBO = 40 V, and V_(BR)EBO = 4.5 V. C_obo ≤ 4.0 pF ensures minimal capacitive loading in high-frequency gate-drive or pulse-amplifier stages.

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 12 V logic or sensor interface circuits.
I_C (continuous)	200 mA - Continuous collector current handling; supports relay drivers, LED arrays, and small-signal power switches without forced cooling.
h_FE min	40 @ I_C = 10 mA, V_CE = 1.0 V - Ensures reliable saturation with modest base drive; eliminates need for excessive I_B margining in microcontroller GPIO-driven stages.
V_CE(sat) max	0.25 V @ I_C = 10 mA, I_B = 1 mA - Limits conduction loss to <2.5 mW at 10 mA; critical for battery-powered signal routing and low-drop bias networks.
t_off	18 ns - Verified turn-off delay under defined test conditions; enables stable operation up to ~20 MHz square-wave switching in non-resonant loads.
R_JA	200°C/W - Thermal resistance from junction to ambient in still air; determines required PCB copper area for sustained 200 mA operation at +70°C ambient.

Pinout & Package

Package: TO-92 (Case 29–11, TO-226AA), through-hole, 3-lead plastic package with standard EBC pinout orientation (Emitter–Base–Collector, viewed from flat side with leads down).

Pin/Terminal	Circuit Role	Design Meaning
Lead 1	Emitter	Reference node for base-emitter junction; connects to ground or low-side return path; polarity-sensitive for correct biasing.
Lead 2	Base	Control input; requires current-limited drive (e.g., 1 kΩ series resistor from 3.3/5 V MCU GPIO) to achieve specified saturation.
Lead 3	Collector	Switched output node; connects to load (e.g., LED anode, relay coil, pull-up resistor); carries full I_C during conduction.

Key Features

Feature	Design Value
Guaranteed h_FE minimum	40 at I_C = 10 mA/V_CE = 1.0 V - Enables deterministic base resistor selection without worst-case overdesign.
Low V_CE(sat)	≤0.25 V - Reduces power dissipation in high-duty-cycle switching; improves efficiency in always-on bias circuits.
Fast switching	t_off ≤ 18 ns - Supports clean edge integrity in clock distribution, pulse shaping, and digital isolation interfaces.
Wide temperature range	–55°C to +150°C T_J - Validated operation in automotive under-hood, industrial motor controls, and outdoor sensor nodes.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MMBT2222ALT1G	V_CEO = 40 V, I_C = 600 mA, SOT-23 package, h_FE min = 100 @ 150 mA	Higher voltage/current rating; surface-mount only; unsuitable for through-hole legacy designs	Select when board space is constrained and higher I_C headroom is needed; requires rework of footprint and thermal layout.
PN2222A	V_CEO = 30 V, I_C = 800 mA, TO-92, h_FE min = 75 @ 10 mA	Higher breakdown and gain; slightly slower t_off (30 ns typical); same package and pinout	Drop-in replacement if V_CEO > 15 V or h_FE > 40 is required; no PCB changes needed.

Compared with MPS2369AG, MMBT2222ALT1G offers superior current capability and voltage margin but demands SMT assembly and revised thermal design, while PN2222A provides direct TO-92 compatibility with enhanced V_CEO and h_FE - making it the preferred upgrade path for existing through-hole layouts requiring higher robustness.

FAQ

What is the maximum continuous collector current rating for the MPS2369AG?

The MPS2369AG is rated for a maximum continuous collector current (I_C) of 200 mA at T_A = 25°C. Derating is required above 25°C at 5.0 mW/°C, meaning usable I_C drops to approximately 150 mA at 70°C ambient. This rating assumes proper PCB copper area for heat dissipation and applies only under DC or low-duty-cycle pulsed conditions - not repetitive high-frequency switching without thermal analysis.

Does the MPS2369AG have a guaranteed minimum DC current gain (h_FE)?

Yes, the MPS2369AG guarantees h_FE ≥ 40 when tested at I_C = 10 mA and V_CE = 1.0 Vdc. This minimum is specified across the full operating temperature range (–55°C to +150°C), though actual values may reach 120 at room temperature. Designers can rely on this minimum to size base resistors confidently without overdriving GPIO pins.

What is the collector-emitter saturation voltage (V_CE(sat)) of the MPS2369AG under standard test conditions?

The MPS2369AG specifies V_CE(sat) ≤ 0.25 V when I_C = 10 mA and I_B = 1.0 mA at T_A = 25°C. At elevated temperatures (+125°C), V_CE(sat) increases to ≤ 0.30 V. This low saturation voltage minimizes power loss and maintains voltage headroom in low-voltage logic interfaces and LED driver circuits using the MPS2369AG.

Is the MPS2369AG suitable for high-frequency switching applications?

The MPS2369AG supports switching up to ~20 MHz based on its specified t_off ≤ 18 ns and t_on ≤ 12 ns, but it is optimized for medium-speed digital switching rather than RF operation. Its C_obo ≤ 4.0 pF and f_T not specified mean it should not be used in tuned amplifier or oscillator circuits. For clean square-wave generation below 5 MHz, the MPS2369AG performs reliably in logic-level translation and pulse gating roles.

What is the package type and pin configuration of the MPS2369AG?

The MPS2369AG uses the TO-92 (Case 29–11) through-hole package with standard EBC pinout: Lead 1 = Emitter, Lead 2 = Base, Lead 3 = Collector, when viewed from the flat side with leads pointing downward. This matches JEDEC TO-226AA mechanical dimensions and is compatible with legacy socketing, wave soldering, and manual prototyping workflows requiring the MPS2369AG.
