Product details

Overview

MMDT3906V-7 from Diodes Incorporated is a dual PNP small-signal transistor in SOT-563 package, rated for V_CEO = −40 V, I_C = −200 mA, and P_D = 150 mW. It delivers h_FE = 60–300 (at I_C = −100 µA to −100 mA), V_CE(SAT) ≤ −0.40 V (I_C = −50 mA), and f_T = 250 MHz, enabling low-power switching and amplification in space-constrained automotive and industrial control circuits.

For engineers reviewing the MMDT3906V-7 datasheet, MMDT3906V-7 pinout, MMDT3906V-7 application, or MMDT3906V-7 equivalent, key selection criteria include dual-PNP configuration, AEC-Q101 qualification, SOT-563 footprint compatibility, −40 V breakdown ratings, and verified h_FE vs. I_C performance across −100 µA to −100 mA.

Technical Context

This dual PNP transistor uses epitaxial planar die construction for stable gain and low leakage. Its symmetric structure supports independent channel operation with matched V_(BR)CEO, V_CE(SAT), and h_FE characteristics across both transistors under identical bias conditions.

Designed for high-reliability surface-mount applications, it operates from −55 °C to +150 °C and meets J-STD-020C Level 1 moisture sensitivity. The SOT-563 package features matte tin-plated Alloy 42 leads and UL 94V-0 mold compound, supporting automated assembly and automotive-grade thermal cycling.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−40 V: Maximum safe collector-emitter voltage before avalanche conduction in switching or linear mode.
I_C (max)	−200 mA: Continuous DC collector current limit per transistor; defines maximum load drive capability.
P_D	150 mW @ T_A = 25 °C: Power dissipation limit on standard FR-4 PCB; derates linearly above 25 °C per Fig. 1.
h_FE	60–300: DC current gain range across I_C = −100 µA to −100 mA; enables predictable base drive sizing.
f_T	250 MHz: Transition frequency at V_CE = −20 V, I_C = −10 mA; supports RF amplification up to ~100 MHz.
V_CE(SAT)	≤ −0.40 V @ I_C = −50 mA, I_B = −5 mA: Low saturation voltage ensures minimal power loss in digital switching.
NF	≤ 4.0 dB @ V_CE = −5 V, I_C = −100 µA: Noise figure suitable for low-level analog preamplifier stages.

Pinout & Package

Package: SOT-563 - ultra-small 6-pin surface-mount plastic package (1.60 mm × 1.20 mm × 0.60 mm), UL 94V-0 rated, lead-free and RoHS compliant, qualified to AEC-Q101.

Pin/Terminal	Circuit Role	Design Meaning
1	Emitter of Transistor 1	Common emitter connection point for first PNP; tied to local ground reference in switch configurations.
2	Base of Transistor 1	Control input for first transistor; requires current-limited drive to avoid exceeding I_B(max).
3	Collector of Transistor 1	Output node for first transistor; connects to load or next stage; reverse-biased during cutoff.
4	Collector of Transistor 2	Output node for second transistor; electrically isolated from Pin 3; supports dual independent loads.
5	Base of Transistor 2	Independent control input for second PNP; enables synchronous or separate switching control.
6	Emitter of Transistor 2	Second emitter terminal; may be tied to same or separate ground plane depending on circuit topology.

Key Features

Feature	Design Value
Dual PNP configuration	Two matched, isolated PNP transistors in one SOT-563 package-reduces board area by ~40% vs. discrete SOT-23 solutions.
AEC-Q101 qualification	Validated for automotive applications including engine control modules and body electronics requiring −40 °C to +125 °C operation.
Low V_CE(SAT)	≤ −0.40 V at I_C = −50 mA ensures <10 mW conduction loss per transistor-critical for battery-powered logic interfaces.
High f_T	250 MHz transition frequency supports signal amplification in IR receivers, sensor front-ends, and low-noise preamps up to 100 MHz.
Moisture Sensitivity Level 1	No bake required prior to reflow; compatible with standard SMT assembly lines without special handling protocols.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual PNP switching and amplification applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMT3906W-7	SOT-363 package (larger footprint); identical electrical specs but higher R_θJA = 900 °C/W.	Less suitable for ultra-dense layouts; better thermal margin only if board copper area is limited.	Select when existing SOT-363 land pattern must be reused and AEC-Q101 compliance is not required.
NSVT3906MUTBG	Same SOT-563 package; h_FE min = 100 @ I_C = −10 mA (tighter bin); no AEC-Q101 qualification.	Preferred for consumer-grade high-gain amplifiers; not approved for automotive safety-critical functions.	Choose for cost-sensitive non-automotive designs needing guaranteed minimum h_FE at mid-current levels.

Compared with DMT3906W-7 and NSVT3906MUTBG, MMDT3906V-7 uniquely combines AEC-Q101 qualification, SOT-563 miniaturization, and verified −40 V breakdown in a single device-making it the only option qualified for space-constrained automotive switching where reliability and footprint are jointly critical.

FAQ

Is MMDT3906V-7 pin-compatible with SOT-23 dual transistors?

No. MMDT3906V-7 uses the 6-pin SOT-563 package with pinout E1-B1-C1-C2-B2-E2, whereas standard dual SOT-23 variants (e.g., MMBT3906) use 6-pin SOT-363 with different pin mapping. Direct replacement requires PCB layout revision and verification of thermal performance due to differing R_θJA.

What is the maximum operating temperature for continuous use?

The MMDT3906V-7 is rated for junction and storage temperatures from −55 °C to +150 °C. For continuous operation, ambient temperature must be limited to ensure junction temperature remains ≤150 °C-derating begins at 25 °C per the 833 °C/W R_θJA, reaching zero power at ~140 °C ambient on standard FR-4.

Does the "Green" designation affect electrical performance?

No. The "Green" designation refers solely to halogen-free molding compound used in date codes UO (2007 week 40) and newer. Electrical parameters-including V_(BR)CEO, h_FE, and f_T-are identical between Green and non-Green versions; only environmental compliance differs.

Can MMDT3906V-7 be used in linear amplifier configurations?

Yes. With h_FE specified from −100 µA to −100 mA and NF ≤ 4.0 dB at low currents, it supports Class-A common-emitter amplifiers. Designers must ensure V_CE remains ≥ −1.0 V and power dissipation stays within 150 mW derated for ambient temperature to avoid thermal runaway.
