Product details

Overview

MPS2369 from onsemi is an NPN silicon switching transistor in TO-92 package, rated for 40 V_CEO, 200 mA continuous collector current, and 625 mW power dissipation at 25°C. It delivers h_FE ≥40 at I_C = 10 mA / V_CE = 1.0 V, V_CE(sat) ≤0.25 V at I_C = 10 mA / I_B = 1 mA, and switching times of t_on ≤12 ns, t_off ≤18 ns - enabling use in low-voltage logic-level interface and signal switching circuits.

For engineers reviewing the MPS2369 datasheet, pinout, applications, or equivalent options, key selection criteria include its guaranteed V_CEO = 15 V (MPS2369) vs. 40 V (MPS2369A), temperature-stable h_FE down to –55°C, low C_obo = 4.0 pF, and TO-92 mechanical compatibility with legacy through-hole PCB layouts.

Technical Context

The MPS2369 operates as a general-purpose NPN bipolar junction transistor optimized for fast-switching applications where low saturation voltage and nanosecond-scale turn-on/turn-off times are required. Its design supports DC amplification and digital switching in low-power analog and mixed-signal systems.

It features a maximum V_CEO of 15 V and V_CES/V_CBO of 40 V, allowing safe operation under transient overvoltage conditions while maintaining tight V_BE(sat) control (0.7–1.6 V across temperature). Thermal resistance R_JA = 200°C/W confirms suitability for ambient-temperature-limited board-level designs without forced cooling.

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 for logic-level switching.
I_C (continuous)	200 mA - Sustained load current capability; supports driving LEDs, small relays, or gate inputs without derating below 25°C.
h_FE @ 10 mA / 1.0 V	40–120 - DC current gain range ensures reliable base drive sizing for saturated switch operation in production designs.
V_CE(sat) @ 10 mA / 1 mA	≤0.25 V - Low saturation voltage minimizes power loss and self-heating during on-state conduction.
t_on / t_off	≤12 ns / ≤18 ns - Nanosecond switching enables use in >10 MHz digital signal routing and pulse-width modulation circuits.
C_obo	4.0 pF - Small output capacitance preserves high-frequency response and reduces capacitive loading on driving stages.

Pinout & Package

Package: TO-92 (Case 29–11, TO-226AA), through-hole, epoxy-molded plastic with 3 leads. Standard lead configuration: Emitter (lead 1), Base (lead 2), Collector (lead 3).

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current exit path for majority carriers	Connected to ground or low-side return; determines common-emitter topology and bias reference point.
2 (Base)	Control terminal for minority carrier injection	Receives TTL/CMOS-compatible drive current (≥1 mA typical); requires series resistor for current limiting.
3 (Collector)	Current entry path for majority carriers	Connected to load and positive supply; handles full switched current and must route heat via PCB copper.

Key Features

Feature	Design Value
Guaranteed V_CEO = 15 V	Enables direct replacement in legacy 12 V logic interface designs where higher-voltage variants risk overstress.
Low V_CE(sat) ≤ 0.25 V	Reduces conduction loss to <1 mW at 10 mA, supporting thermally constrained PCBs and battery-powered systems.
Fast switching (t_on + t_off < 30 ns)	Supports clean edge integrity in clock distribution, pulse shaping, and digital isolation circuits up to 30 MHz.
Specified operation from –55°C to +150°C	Validates functionality across automotive under-hood, industrial control, and outdoor embedded environments.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC547B	V_CEO = 45 V, h_FE = 200–450 (higher gain, wider spread), TO-92 package identical	Higher gain allows lower base drive but less predictable saturation behavior at low I_C	Select BC547B when higher DC gain is needed and V_CEO margin >30 V is required; verify V_CE(sat) at target I_C.
2N3904	V_CEO = 40 V, t_on/t_off = 10/15 ns (slightly faster), same TO-92 footprint and pinout	Broader industry adoption and tighter parametric consistency across manufacturers	Choose 2N3904 for new designs requiring long-term supply stability and cross-supplier second sourcing.

Compared with BC547B and 2N3904, the MPS2369 offers a defined 15 V V_CEO ceiling ideal for 12 V systems where overvoltage robustness is unnecessary - simplifying safety margin analysis and reducing risk of unintended avalanche conduction.

FAQ

What is the maximum collector-emitter voltage rating for MPS2369?

The MPS2369 has a guaranteed V_CEO rating of 15 Vdc under specified test conditions (I_C = 10 mA, I_B = 0). This distinguishes it from the MPS2369A variant, which specifies 40 V. Designers must observe this 15 V limit in all operating conditions to ensure reliability and avoid breakdown.

Does MPS2369 support operation at elevated temperatures?

Yes, the MPS2369 is characterized for operation from –55°C to +150°C junction temperature. Its h_FE and V_CE(sat) parameters are tested at –55°C and +125°C, confirming stable switching performance in automotive under-hood and industrial control environments where ambient temperatures exceed 85°C.

Is MPS2369 pin-compatible with other TO-92 NPN transistors?

The MPS2369 uses standard TO-92 (Case 29–11) mechanical dimensions and E-B-C pinout (lead 1 = emitter, lead 2 = base, lead 3 = collector), matching 2N3904, BC547, and PN2222A. Physical fit is assured, but electrical compatibility must be verified per application requirements including V_CEO, h_FE, and switching speed.

What is the typical storage time (t_s) for MPS2369?

The MPS2369 exhibits a typical storage time t_s of 5.0 ns under standard test conditions (I_B1 = I_B2 = I_C = 10 mA). This short delay contributes to its overall fast switching profile and supports clean signal transitions in high-speed digital interface applications.

Can MPS2369 be used in linear amplifier configurations?

While the MPS2369 is optimized for switching, its h_FE specification (40–120 at I_C = 10 mA) and low noise characteristics support basic Class-A small-signal amplification. However, onsemi positions it primarily for saturated switching; for precision analog gain, dedicated amplifier transistors like BC549C are recommended.
