Product details

Overview

MMSTA06Q-7-F from Diodes Incorporated is an AEC-Q101-qualified 80V NPN small-signal bipolar junction transistor in SOT323 package, rated for 500mA collector current and 200mW power dissipation, with DC current gain (h_FE) ≥100 at 10mA/1V, used in automotive load switching and signal amplification circuits.

For engineers reviewing the MMSTA06Q-7-F datasheet, MMSTA06Q-7-F pinout, MMSTA06Q-7-F application, or MMSTA06Q-7-F equivalent, key selection criteria include V_CEO = 80V, I_C = 500mA, h_FE ≥100 @ 10mA, V_CE(SAT) ≤ 0.25V @ 100mA/10mA, and AEC-Q101 qualification for under-hood automotive use.

Technical Context

This NPN BJT employs epitaxial planar die construction for stable high-voltage operation and thermal robustness across −55°C to +150°C ambient range. Its 80V V_CEO and 4V V_EBO support high-side switching in 24V automotive systems, while f_T = 100MHz enables RF-coupled preamplifier stages.

The device delivers V_CE(SAT) ≤ 0.25V at I_C = 100mA/I_B = 10mA and maintains h_FE ≥100 over 0.1–100mA collector current range, enabling predictable biasing in linear and saturated-mode applications without external compensation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	80V - supports switching in 24V automotive power rails with 3× safety margin
I_C	500mA - handles peak loads in body control modules and LED drivers
P_D	200mW - limits thermal rise on 1oz FR-4 PCB with R_θJA = 625°C/W
h_FE	≥100 @ 10mA/1V - ensures reliable base drive in low-power logic interface circuits
f_T	100MHz - enables use in IF amplifiers and fast-switching sensor signal conditioning
ESD HBM	4000V - meets automotive ESD immunity requirements per JESD22-A114

Pinout & Package

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC846B,215	V_CEO = 65V, I_C = 100mA, non-AEC-Q101	Limited to 12V consumer electronics; not qualified for automotive under-hood use	Select only for cost-sensitive non-automotive designs where 80V rating and AEC-Q101 are unnecessary
MMBT3904LT1G	V_CEO = 40V, I_C = 200mA, AEC-Q101 qualified	Insufficient voltage margin for 24V load-dump environments; lower current capability	Acceptable only in 12V systems with strict thermal management and derated voltage operation

Compared with BC846B,215 and MMBT3904LT1G, MMSTA06Q-7-F uniquely combines 80V breakdown, 500mA current, and AEC-Q101 qualification-enabling single-part compliance for 24V automotive switching without voltage derating or secondary protection.

FAQ

What is the maximum continuous collector current for MMSTA06Q-7-F?

The absolute maximum continuous collector current is 500mA at T_A = +25°C. Derating applies above 25°C ambient: linear reduction to zero at +150°C case temperature, governed by R_θJA = 625°C/W and P_D = 200mW limit. Operation above 300mA requires thermal pad design per Diodes' SOT323 layout guidelines.

Is MMSTA06Q-7-F suitable for linear amplification applications?

Yes-its h_FE ≥100 over 0.1–100mA and f_T = 100MHz support low-noise, medium-gain amplification in sensor front-ends. However, V_CE(SAT) and thermal resistance make it less optimal than dedicated RF transistors for >10MHz analog signal paths.

Does MMSTA06Q-7-F have a complementary PNP part?

Yes-the MMSTA56Q is the AEC-Q101-qualified complementary PNP transistor, sharing identical SOT323 packaging, 80V ratings, 500mA current capability, and automotive qualification. Both are marked with K1G code and support matched pair design in H-bridge or differential amplifier topologies.

What does the "-7-F" suffix indicate in MMSTA06Q-7-F?

The "-7-F" denotes tape-and-reel packaging: 7-inch reel diameter, 8mm tape width, and 3,000 units per reel. The "F" confirms full RoHS compliance and halogen-free ("Green") status per Diodes Incorporated's specification, distinct from non-"F" variants that may lack antimony/bromine/chlorine restrictions.
