Product details
Overview
MMBT2369LT1G from onsemi is an NPN silicon switching transistor in SOT-23 package, rated for 15 VCEO, 200 mA continuous collector current, and 225 mW power dissipation on FR-5 board; optimized for low-voltage digital switching in portable logic interfaces and signal routing circuits.
For engineers reviewing the MMBT2369LT1G datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed hFE ≥40 at 10 mA/1.0 V, VCE(sat) ≤0.25 V at IC/IB = 10 mA/1 mA, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device operates as a general-purpose NPN bipolar junction transistor with fixed-emitter configuration, designed for saturated switching rather than linear amplification. Its electrical behavior is defined by DC current gain (hFE) ≥40 at IC = 10 mA, VCE = 1.0 V, and VCE(sat) ≤0.25 V under identical bias conditions.
Thermal performance is specified for two PCB substrates: 225 mW max dissipation on FR-5 (derating 1.8 mW/°C above 25°C) and 300 mW on alumina (derating 2.4 mW/°C), with corresponding RJA values of 556 °C/W and 417 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 15 V - Maximum safe collector-emitter voltage before breakdown in open-base configuration; defines upper rail limit for 3.3 V and 5 V logic-level switching. |
| IC (continuous) | 200 mA - Absolute maximum DC collector current; supports driving small relays, LEDs, or logic gates without external heat sinking. |
| hFE (min) | 40 at IC = 10 mA, VCE = 1.0 V - Ensures reliable saturation with modest base drive; enables use with microcontroller GPIOs sourcing ≥1 mA. |
| VCE(sat) (max) | 0.25 V at IC/IB = 10 mA/1 mA - Minimizes conduction loss and self-heating during on-state operation in battery-powered systems. |
| toff (max) | 18 ns at VCC = 3 V, IC = 10 mA - Supports switching frequencies up to ~10 MHz in non-critical timing paths with fast turn-off response. |
| RJA (FR-5) | 556 °C/W - Indicates thermal resistance when mounted on standard epoxy-glass PCB; requires layout attention for >100 mA average loads. |
Pinout & Package
SOT-23 (TO-236) surface-mount plastic package, 2.90 mm × 1.30 mm × 1.00 mm body size, lead pitch 1.90 mm, Pb-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input terminal; accepts TTL/CMOS-compatible base current to switch collector-emitter path. |
| 2 | Emitter | Common reference node; tied to ground or low-side return path in most switching configurations. |
| 3 | Collector | Output terminal; connects to load (e.g., LED anode or relay coil) and high-side supply rail. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control modules and body electronics requiring extended temperature and reliability compliance. |
| Pb-free, halogen-free/BFR-free | Meets global environmental regulations (RoHS, ELV) without compromising solderability or long-term interconnect integrity. |
| Low VCE(sat) at 10 mA | Reduces power loss to <1 mW in typical logic interface use cases, extending battery life in portable devices. |
| Fast switching (toff ≤18 ns) | Enables clean digital waveform reproduction in clock buffering and pulse shaping circuits up to 10 MHz. |
| High VCBO/VCES = 40 V | Provides margin against transient voltage spikes in 12 V automotive and industrial supply rails. |
Applications
| Automotive Body Control Module | Portable Device Power Sequencing |
|---|---|
Use Scenario: Driving door lock actuators and interior lighting via microcontroller GPIOs in 12 V vehicle networks. IC Role / Device Role / Timing Role: Low-side switch controlling current path to resistive/inductive loads. Use Value: Guaranteed VCE(sat) ≤0.25 V ensures <2.5 mW conduction loss at 10 mA, minimizing thermal stress in sealed modules. |
Use Scenario: Enabling/disabling subsystem power rails (e.g., display backlight, sensor interface) in smartphones and wearables. IC Role / Device Role / Timing Role: Discrete load switch activated by application processor output pins. Use Value: 18 ns toff supports rapid power-state transitions required for dynamic power management firmware. |

IC Role / Device Role / Timing Role: Interface transistor converting industrial voltage levels to logic-compatible signals. Use Value: 40 V VCBO rating provides immunity to common-mode transients on factory floor wiring. |
Use Scenario: Isolating microcontroller outputs from motor drivers or solenoid coils in washing machines and HVAC controls. IC Role / Device Role / Timing Role: General-purpose switching element decoupling control logic from higher-power stages. Use Value: AEC-Q101 qualification ensures robustness against vibration, thermal cycling, and ESD events in home appliance 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 |
|---|---|---|---|
| BC846BTT1G | Higher hFE (min 200 vs. 40), same SOT-23 package and 65 V VCBO; lower IC rating (100 mA). | Better suited for low-current amplification or high-gain switching where base drive is limited. | Select BC846BTT1G when gain stability at sub-1 mA base current is critical; avoid for >100 mA loads. |
| PN2222A-AP | TO-92 through-hole package, 40 V VCBO, hFE min 75 at 10 mA, but larger footprint and no AEC-Q101 qualification. | Used in legacy designs or prototyping where manual assembly or socketing is preferred. | Choose PN2222A-AP only for non-automotive, non-volume production where SMT constraints do not apply. |
Compared with BC846BTT1G and PN2222A-AP, the MMBT2369LT1G offers the optimal balance of automotive qualification, moderate gain, and 200 mA capability in a compact SOT-23 footprint-making it preferred for space-constrained, production-grade switching in automotive and industrial edge nodes.

FAQ
What is the maximum operating temperature range for the MMBT2369LT1G?
The MMBT2369LT1G has a specified junction and storage temperature range of −55°C to +150°C. This wide range supports deployment in under-hood automotive locations and industrial enclosures exposed to ambient extremes. The device maintains parametric performance within datasheet limits across this full span when derated per thermal characteristics.
Is the MMBT2369LT1G suitable for linear amplifier applications?
No-the MMBT2369LT1G is characterized and optimized for saturated switching operation, not linear amplification. Its hFE and VCE(sat) specifications are validated only at switching-relevant bias points (e.g., IC = 10 mA, VCE = 1.0 V), and small-signal parameters like hfe (5.0 at 100 MHz) are provided for switching-edge analysis-not analog gain design.
Does the MMBT2369LT1G have built-in ESD protection?
The MMBT2369LT1G does not integrate dedicated ESD protection circuitry. It meets standard human-body model (HBM) ESD ratings per AEC-Q101 (≥2 kV), but external TVS diodes or series resistors are recommended when used in connector-facing or user-accessible circuits to prevent latch-up or permanent damage.
What does the "T1G" suffix indicate in MMBT2369LT1G?
The "T1G" suffix denotes tape-and-reel packaging (3,000 units per reel) and Pb-free (RoHS-compliant) construction. The "G" specifically confirms compliance with lead-free soldering standards and absence of hazardous substances per EU RoHS Directive 2011/65/EU and related amendments.
Can the MMBT2369LT1G replace the MMBT2222ALT1G in existing designs?
Direct replacement is not recommended: the MMBT2222ALT1G has higher VCEO (40 V vs. 15 V) and different hFE distribution. Substituting MMBT2369LT1G into a 24 V circuit risks VCEO overstress. Verify voltage margins, gain requirements, and saturation behavior before interchange-no pin-to-pin or functional equivalence is claimed.
