Product details

Overview

MMBTA06-7-F from Diodes Incorporated is an NPN medium-power bipolar junction transistor in SOT23 package, rated for 80 V V_CEO, 500 mA I_C, and 350 mW P_D (on 15 mm × 15 mm PCB), optimized for low-power amplification and switching in space-constrained industrial and consumer circuits.

For engineers reviewing the MMBTA06-7-F datasheet, MMBTA06-7-F pinout, MMBTA06-7-F application, or MMBTA06-7-F equivalent, key selection criteria include its 80 V collector-emitter breakdown voltage, 100–300 DC current gain at 10 mA, 0.25 V V_CE(sat) at 100 mA/10 mA drive, 100 MHz f_T, and SOT23 thermal resistance of 357 °C/W (junction-to-ambient).

Technical Context

This NPN transistor uses epitaxial planar die construction to ensure stable gain and low leakage across temperature. Its 4.0 V V_EBO and 100 nA I_CBO at 80 V support reliable biasing in low-voltage control stages and signal conditioning paths.

The device operates over −55 °C to +150 °C and meets JEDEC Class 3A HBM ESD rating (4 kV), making it suitable for non-automotive industrial environments where transient immunity and thermal robustness are required without automotive qualification.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	80 V - Maximum safe collector-emitter voltage before avalanche conduction in switching or linear operation.
I_C	500 mA - Continuous collector current limit defining usable load drive capability in amplifier or switch mode.
P_D	350 mW - Max power dissipation on 15 mm × 15 mm 1 oz copper PCB, setting thermal design margin for steady-state operation.
h_FE	100–300 - DC current gain range at 10 mA I_C/1 V V_CE, enabling predictable base drive sizing in saturated switching.
f_T	100 MHz - Transition frequency indicating usable bandwidth for small-signal amplification up to ~10 MHz with gain >1.
V_CE(sat)	0.25 V - Collector-emitter saturation voltage at 100 mA I_C/10 mA I_B, directly determining conduction loss in digital logic interface or relay driver stages.
R_θJA	357 °C/W - Junction-to-ambient thermal resistance on specified PCB layout, used to calculate junction temperature rise under load.

Pinout & Package

Package: SOT23 - Surface-mount plastic package measuring 2.90 mm × 1.30 mm × 1.03 mm (H × C × D), UL 94V-0 rated, with matte tin-plated leads solderable per MIL-STD-202.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current sink terminal	Reference node for base-emitter bias; connects to ground or low-side return path in common-emitter configurations.
2 (Base)	Control input	Receives forward-biased current to modulate collector current; requires series resistor to limit I_B and prevent saturation delay.
3 (Collector)	Current source terminal	Delivers amplified or switched current to load; connects to supply rail in low-side switch or active load in amplifier stage.

Key Features

Feature	Design Value
Epitaxial planar die construction	Ensures tight parameter distribution and stable h_FE vs. temperature, critical for consistent gain in analog front-ends.
Complementary PNP pairing	Directly mates with MMBTA56 for push-pull output stages or differential pair designs without gain mismatch.
Lead-free & halogen-free "Green" compliance	Meets RoHS 3 (2015/863/EU) and halogen limits (<900 ppm Br/Cl, <1000 ppm Sb), supporting eco-conscious manufacturing.
JEDEC Class 3A HBM ESD rating	Withstands 4 kV human-body model discharge, reducing need for external protection in board-level handling and assembly.

Applications

LED Driver Circuit

Microcontroller GPIO Interface

Use Scenario: Driving 20 mA indicator LEDs from 3.3 V or 5 V microcontroller outputs.

IC Role / Device Role / Timing Role: Low-side switch controlling LED current path to ground via saturated NPN operation.

Use Value: 0.25 V V_CE(sat) minimizes voltage drop and power loss, preserving LED forward voltage margin and brightness consistency.

Use Scenario: Level-shifting or current boosting between MCU I/O pins and higher-current peripherals (e.g., sensors, relays).

IC Role / Device Role / Timing Role: Digital buffer/amplifier translating weak GPIO signals into robust 100 mA capable drive.

Use Value: 100–300 h_FE enables reliable turn-on with ≤1 mA base drive, reducing MCU pin loading and timing uncertainty.

Low-Voltage Signal Amplifier

Power Supply Enable Switch

Use Scenario: Small-signal preamplification of sensor outputs (e.g., thermistor, photodiode) in battery-powered devices.

IC Role / Device Role / Timing Role: Common-emitter amplifier stage providing voltage gain with minimal quiescent current.

Use Value: 100 MHz f_T supports bandwidths up to 10 MHz, sufficient for audio and sub-MHz sensor signal conditioning.

Use Scenario: Enabling/disabling auxiliary rails (e.g., 3.3 V LDO input) using a logic-controlled high-side or low-side switch.

IC Role / Device Role / Timing Role: Low-side enable switch turning on/off power path based on system control signal.

Use Value: 80 V V_CEO provides headroom above typical 24 V industrial rails, ensuring safe operation during transients.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN medium-power transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MMBT3904-7-F	Lower V_CEO (40 V), lower P_D (310 mW), same SOT23 package and pinout.	Not suitable for 24 V+ supply rails or higher-power loads requiring >310 mW dissipation.	Select when operating below 40 V and thermal budget is tighter; verify SOA fit for pulse loads.
PN2222A-AP	TO-92 package, higher P_D (625 mW), but larger footprint and different pinout (E-B-C vs. E-B-C SOT23).	Requires PCB redesign; unsuitable for automated SMT assembly or dense layouts.	Choose only if through-hole mounting is mandatory and thermal demand exceeds 350 mW on SOT23.

Compared with MMBT3904-7-F and PN2222A-AP, MMBTA06-7-F uniquely balances 80 V breakdown, SOT23 compactness, and 350 mW power handling-making it optimal for modern industrial controls where voltage headroom and board space are both constrained.

FAQ

What is the maximum continuous collector current for MMBTA06-7-F?

The maximum continuous collector current is 500 mA at T_A = +25°C, derated linearly above 25°C per the datasheet's thermal curve. At 100°C ambient, usable I_C drops to approximately 350 mA due to the 357 °C/W R_θJA and 350 mW P_D limit. Peak pulsed current reaches 1 A for ≤100 µs with 2% duty cycle.

Is MMBTA06-7-F pin-compatible with MMBTA05-7-F?

Yes-both share identical SOT23 package and pinout (Emitter-Base-Collector on pins 1-2-3). However, MMBTA05-7-F has lower 60 V V_CEO/V_CB0 ratings and 310 mW P_D, so substitution is only valid in circuits operating ≤60 V and within the lower power envelope.

Does MMBTA06-7-F support automotive applications?

No-MMBTA06-7-F is not AEC-Q101 qualified. Diodes offers the automotive-grade MMBTA06Q-7-F variant, which undergoes additional stress testing and lot traceability per AEC standards. Use MMBTA06Q-7-F for automotive body electronics or infotainment systems.

What is the typical DC current gain at 100 mA collector current?

At I_C = 100 mA and V_CE = 1.0 V, h_FE is typically 100 (minimum guaranteed), with typical values ranging 150–250 depending on unit variation and temperature. The datasheet graph shows h_FE decreases gradually above 30 mA, confirming suitability for moderate-current switching rather than high-gain linear amplification.
