Product details
Overview
MMBTA06WT1 from ON Semiconductor is an NPN silicon small-signal driver transistor in SC-70 (SOT-323) package, rated for 80 VCEO, 500 mA continuous collector current, and 460 mW power dissipation at TA = 25°C. It delivers hFE ≥ 100 at IC = 10 mA, VCE = 1.0 V, and fT = 100 MHz, supporting high-speed switching in low-voltage interface and signal amplification circuits.
For engineers reviewing the MMBTA06WT1 datasheet, pinout, applications, or equivalent options, key selection criteria include its 80 V breakdown rating, 100 MHz fT, ESD robustness (HBM 4 kV), AEC-Q101 qualification, and SC-70 footprint compatibility with space-constrained PCB layouts.
Technical Context
The MMBTA06WT1 operates as a general-purpose NPN amplifier/switch with verified DC current gain of ≥100 at 10 mA and ≥100 at 100 mA, and VCE(sat) ≤ 0.25 V at IC = 100 mA, IB = 10 mA. Its fT = 100 MHz enables stable operation in audio preamp stages and digital logic interfacing up to ~10–20 MHz.
Thermal resistance RJA = 272°C/W on FR-5 board confirms suitability for low-power, thermally unmanaged applications. Junction temperature range of −55°C to +150°C and Pb-free, RoHS-compliant construction support automotive and industrial deployments requiring reliability under thermal stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Supports rail voltages up to 60 V with 20 V margin for transients in 24 V industrial control systems. |
| IC (continuous) | 500 mA - Drives medium-current loads such as LED arrays, relay coils, or gate resistors for MOSFETs without external heat sinking. |
| hFE | ≥100 @ IC = 10 mA - Ensures reliable base drive with low input current in discrete amplifier or switch configurations. |
| fT | 100 MHz - Enables use in broadband signal conditioning, pulse shaping, and clock buffer applications below 30 MHz. |
| VCE(sat) | ≤0.25 V @ IC/IB = 10 - Minimizes conduction loss and self-heating in saturated-switch mode, improving efficiency in digital output stages. |
| RJA | 272°C/W - Limits junction rise to <14°C above ambient at 460 mW dissipation on standard FR-5 PCB, enabling passive thermal design. |
Pinout & Package
MMBTA06WT1 uses the SC-70 (SOT-323) surface-mount package (Case 419, Style 3), measuring 2.1 mm × 1.24 mm × 0.9 mm with gull-wing leads. Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Base) | Control input terminal | Receives forward-biased current to turn on the transistor; requires series resistor to limit IB per hFE and load requirements. |
| 2 (Emitter) | Current return path | Connected to ground or low-side reference; provides common node for biasing and feedback in emitter-follower or common-emitter topologies. |
| 3 (Collector) | Output current terminal | Sinks load current from VCC; must be routed with adequate trace width to handle 500 mA peak without excessive IR drop or heating. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics including body control modules and sensor interfaces where reliability across temperature and vibration is mandatory. |
| HBM ESD rating: 4 kV | Withstands electrostatic discharge during handling and assembly without protection diodes, reducing BOM count in ESD-prone environments. |
| Moisture Sensitivity Level 1 | Zero bake requirement before reflow; compatible with standard JEDEC J-STD-020 moisture-sensitive device (MSD) handling protocols. |
| Pb-free, Halogen-free, RoHS compliant | Meets global environmental compliance mandates for consumer, industrial, and automotive end equipment without lead or brominated flame retardants. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN small-signal transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBT2222ALT1G | VCEO = 40 V (vs. 80 V); hFE min = 100 @ IC = 10 mA; same SC-70 package. | Limited to ≤30 V systems; unsuitable for 48 V industrial or 60 V automotive supply rails where MMBTA06WT1 provides headroom. | Select when lower voltage operation suffices and legacy design reuse is prioritized over breakdown margin. |
| BC846BW | VCEO = 65 V; hFE = 110–220 @ IC = 10 mA; same SC-70 footprint but different marking and tape/reel packaging. | Lower breakdown margin than MMBTA06WT1; tighter hFE distribution may simplify bias design but reduces worst-case gain assurance. | Prefer for cost-sensitive consumer applications where 65 V rating is sufficient and higher hFE improves noise immunity. |
Compared with MMBTA06WT1, MMBT2222ALT1G trades 40 V lower breakdown for broader legacy support, while BC846BW offers higher hFE spread and 15 V less VCEO-making MMBTA06WT1 optimal for 48–60 V systems needing guaranteed 80 V margin and AEC-Q101 compliance.

FAQ
What is the maximum collector-emitter voltage rating for MMBTA06WT1?
The MMBTA06WT1 has a maximum collector-emitter voltage (VCEO) rating of 80 VDC, verified per ON Semiconductor's datasheet under test conditions of IC = 1.0 mA and IB = 0. This rating ensures safe operation in 48 V and 60 V nominal systems with transient margin, and is confirmed by both absolute maximum ratings and breakdown voltage testing in the Electrical Characteristics table.
Is MMBTA06WT1 suitable for automotive applications?
Yes, MMBTA06WT1 is AEC-Q101 qualified and PPAP capable, with S-prefix variants (e.g., SMMBTA06WT1G) explicitly designated for automotive use. Its −55°C to +150°C junction temperature range, 4 kV HBM ESD rating, and moisture sensitivity level 1 make it appropriate for body control modules, lighting drivers, and sensor interfaces in passenger vehicles and commercial fleets.
What package type does MMBTA06WT1 use, and what are its dimensions?
MMBTA06WT1 uses the SC-70 (SOT-323) package (Case 419, Style 3), with nominal dimensions of 2.10 mm × 1.24 mm × 0.90 mm and gull-wing leads. Pin 1 is Base, Pin 2 is Emitter, and Pin 3 is Collector. The package drawing and soldering footprint are fully specified in the ON Semiconductor datasheet revision 5, September 2018.
Does MMBTA06WT1 have a guaranteed minimum DC current gain (hFE)?
Yes, MMBTA06WT1 guarantees hFE ≥ 100 at IC = 10 mA and VCE = 1.0 V, and also ≥ 100 at IC = 100 mA and VCE = 1.0 V, per the Electrical Characteristics table. This dual-point specification ensures consistent gain performance across both low- and medium-current operating regions critical for robust switching and amplification.
What is the thermal resistance (RJA) of MMBTA06WT1, and how does it affect PCB layout?
The MMBTA06WT1 has a thermal resistance RJA of 272°C/W when mounted on an FR-5 board at TA = 25°C. This value assumes standard 1 oz. copper, 100 mm² pad area. To maintain junction temperature within −55°C to +150°C limits, designers must limit power dissipation to ≤460 mW and avoid enclosing the SC-70 package in thermally insulating enclosures or adjacent to high-power components without thermal relief.
