Product details

Overview

MPS2369RLRA 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 (IC = 10 mA, V_CE = 1.0 V), V_CE(sat) ≤ 0.25 V, and t_on/t_off ≤ 12/18 ns - used in low-voltage digital logic interface and LED driver stages.

For engineers reviewing the MPS2369RLRA datasheet, pinout, applications, or equivalent options, key selection criteria include verified DC current gain at low V_CE, guaranteed saturation voltage under 10 mA drive, thermal resistance of 200°C/W, and TO-92 mechanical compatibility for through-hole board assembly.

Technical Context

This discrete NPN transistor operates as a saturated switch in low-power digital and analog signal routing applications. Its design emphasizes fast turn-on (t_on ≤ 12 ns) and turn-off (t_off ≤ 18 ns) with minimal storage time (t_s ≤ 13 ns), enabling reliable operation in 1–10 MHz pulse-width modulation circuits.

It supports emitter-grounded common-emitter configuration with V_BE(sat) = 0.7–0.85 V at I_C = 10 mA and I_B = 1 mA, and maintains C_obo ≤ 4.0 pF at V_CB = 5 V - critical for high-speed switching stability and reduced capacitive loading on driving gates.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	15 V - Maximum collector-emitter voltage before breakdown in common-emitter configuration; defines safe operating range for 5 V and 12 V logic-level switching.
I_C (continuous)	200 mA - Continuous collector current handling capacity; sufficient for driving LEDs, small relays, or logic-level translators.
h_FE (min)	40 at I_C = 10 mA, V_CE = 1.0 V - Ensures reliable saturation with base drive ≥ 250 µA, reducing required MCU GPIO current.
V_CE(sat) (max)	0.25 V - Low saturation voltage minimizes power loss (≤ 2.5 mW at 10 mA) and heat generation in switching mode.
t_off	18 ns - Fast turn-off enables clean signal edges in high-frequency digital interfaces up to 10 MHz.
R_JA	200°C/W - Thermal resistance confirms need for adequate PCB copper area or forced-air cooling above ~150 mW dissipation.

Pinout & Package

Package: TO-92 (Case 29–11, Style 1), through-hole, epoxy-molded plastic with 3 leads. Standard lead formation per JEDEC TO-226AA.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current sink terminal	Connected to ground or low-side return path; must be routed with low-inductance trace for fast switching.
2 (Base)	Control input	Receives TTL/CMOS-compatible drive; requires series resistor (e.g., 1 kΩ) to limit I_B and prevent overdrive.
3 (Collector)	Current source terminal	Connects to load (e.g., LED anode or relay coil); polarity-sensitive - reverse connection risks device failure.

Key Features

Feature	Design Value
Fast switching speed	t_on/t_off ≤ 12/18 ns enables use in 5–10 MHz clocked logic buffers without edge distortion.
Guaranteed h_FE minimum	h_FE ≥ 40 at I_C = 10 mA ensures predictable saturation with standard microcontroller GPIO drive capability.
Low V_CE(sat)	V_CE(sat) ≤ 0.25 V at I_C = 10 mA reduces conduction loss by >60% vs. general-purpose transistors like 2N3904.
TO-92 mechanical standardization	Compatible with legacy through-hole tooling, wave-solder fixtures, and hand-solder repair workflows across industrial PCB assembly lines.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
2N3904RLRPG	Lower h_FE min (30 vs. 40), higher V_CE(sat) (0.3 V), slower t_off (30 ns), same TO-92 package.	Suitable for lower-speed, cost-sensitive designs where gain margin is less critical.	Select when absolute minimum BOM cost is prioritized over switching speed or guaranteed saturation at low I_B.
MPS2222ARLRA	Higher I_C rating (600 mA), higher V_CEO (40 V), larger C_obo (8 pF), same pinout.	Better for 24 V industrial loads but introduces more capacitive loading on high-speed drivers.	Choose when future-proofing for higher-voltage or higher-current loads is required, accepting trade-offs in speed and layout sensitivity.

Compared with 2N3904RLRPG and MPS2222ARLRA, the MPS2369RLRA delivers optimal balance of speed, saturation performance, and thermal efficiency in 5–12 V, <200 mA switching roles - making it preferred for compact, high-reliability digital interface stages where consistent low-V_CE(sat) and sub-20 ns t_off are design-critical.

FAQ

What is the maximum continuous collector current rating for MPS2369RLRA?

The MPS2369RLRA is rated for 200 mA continuous collector current (I_C) at ambient temperature T_A = 25°C. Derating applies above 25°C at 5.0 mW/°C, limiting usable current to ~150 mA at 75°C ambient. This rating assumes proper PCB copper area for thermal dissipation and is validated per onsemi's published test conditions in the MPS2369/D datasheet.

Does MPS2369RLRA support operation at elevated temperatures such as +125°C junction?

Yes, the MPS2369RLRA is specified for operation up to +150°C junction temperature (T_J). At T_A = 125°C, its I_CBO rises to 30 µA and V_CE(sat) increases to 0.30 V - both values remain within functional limits for most switching applications. Thermal design must ensure R_JA × P_D + T_A ≤ 150°C.

Is MPS2369RLRA pin-compatible with the 2N3904 in TO-92 packages?

Yes, MPS2369RLRA uses the standard TO-92 (Case 29–11) package with identical pinout: Emitter (Pin 1), Base (Pin 2), Collector (Pin 3). Mechanical dimensions and lead spacing match JEDEC TO-226AA, enabling direct replacement in existing footprints - though electrical performance (gain, speed, saturation) differs and must be verified per circuit requirements.

What is the typical small-signal current gain (hfe) of MPS2369RLRA at 100 MHz?

The MPS2369RLRA has a minimum small-signal current gain (h_fe) of 5.0 at I_C = 10 mA, V_CE = 10 V, and f = 100 MHz. This value reflects usable RF amplification bandwidth and confirms suitability for narrowband signal switching up to ~50 MHz, though the device is optimized for DC/switching rather than linear RF operation.

Can MPS2369RLRA be used in linear amplifier configurations?

The MPS2369RLRA is characterized and qualified as a switching transistor, not a linear amplifier. While it exhibits h_FE variation across bias points, its datasheet does not specify linearity parameters (e.g., THD, f_T stability, or SOA curves) required for analog amplification. For linear applications, onsemi recommends dedicated amplifiers such as the MMBT5551 or SMMBT3904.
