Product details

Overview

2DC4617R-7-F from Diodes Incorporated is a 50V NPN small-signal transistor in SOT523 package, rated for 150mA continuous collector current, 150mW power dissipation, and 833°C/W junction-to-ambient thermal resistance, with DC current gain (h_FE) of 180–390 at V_CE = 6V and I_C = 1mA, used in compact automotive signal switching and biasing circuits.

For engineers reviewing the 2DC4617R-7-F datasheet, 2DC4617R-7-F pinout, 2DC4617R-7-F application, or 2DC4617R-7-F equivalent, key selection criteria include V_CEO = 50V, I_C = 150mA, h_FE bin R, SOT523 footprint compatibility, AEC-Q101 qualification, and thermal derating behavior above 25°C ambient.

Technical Context

This NPN transistor operates as a linear amplifier or saturated switch in low-power analog and digital interface stages. Its 140–180MHz f_T supports audio-frequency amplification and medium-speed digital switching up to ~50MHz edge rates, while the 7V V_EBO rating enables safe operation with standard logic-level base drive.

The device uses epitaxial planar construction with fully lead-free, halogen- and antimony-free "Green" molding compound, qualified to AEC-Q101 for automotive underhood and infotainment applications requiring -55°C to +150°C operating range and robust ESD immunity (4kV HBM).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - Maximum collector-emitter voltage before breakdown; defines safe operating range in switching and amplifier configurations.
I_C (max)	150 mA - Continuous collector current limit; sets maximum load drive capability in active or saturated mode.
h_FE (R-bin)	180–390 - DC current gain range at V_CE = 6V, I_C = 1mA; determines base drive requirements for reliable saturation.
f_T	140–180 MHz - Transition frequency; indicates usable bandwidth for small-signal amplification and high-speed switching.
R_θJA	833 °C/W - Junction-to-ambient thermal resistance on 1oz FR4; dictates temperature rise under 150mW dissipation in still air.
V_CE(SAT)	≤0.4 V - Collector-emitter saturation voltage at I_C = 50mA, I_B = 5mA; defines conduction loss in switching applications.
ESD HBM	4000 V - Human Body Model rating; ensures robustness against handling-induced electrostatic discharge during assembly.

Pinout & Package

Package: SOT523 - ultra-small surface-mount plastic case (1.60 × 1.60 × 0.75 mm), moisture sensitivity level 1, matte tin-plated leads, weight ≈ 0.002 g.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current sink terminal	Reference node for bias network; connects to ground or low-impedance return path in common-emitter configurations.
2 (Base)	Control input	Receives current-limited drive to modulate collector current; requires series resistor to limit I_B per h_FE and V_BE ≈ 0.7V.
3 (Collector)	Current source terminal	Delivers switched or amplified output current; connects to load and supply rail in typical NPN switch topology.

Key Features

Feature	Design Value

Ultra-small SOT523 footprint	1.6mm × 1.6mm outline enables high-density PCB layouts in space-constrained modules like ADAS sensors and LED drivers.
High h_FE bin R (180–390)	Reduces required base drive current by up to 2× vs. lower-gain transistors, lowering MCU GPIO loading and improving system power efficiency.
Lead-free & "Green" compliant	Meets RoHS 3 (2015/863/EU), halogen-free (<900ppm Br/Cl), and antimony-free (<1000ppm) standards for eco-conscious manufacturing.
Low V_CE(SAT) (≤0.4V)	Minimizes conduction loss in saturated switching, enabling higher efficiency in 3.3V/5V logic-level driven loads such as relays and LEDs.

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
DXT4617R-7	Same h_FE bin (180–390), identical SOT523 package, but rated only to 100mA I_C and 100mW P_D.	Not suitable for 150mA continuous loads; limited to lower-power biasing and signal routing.	Select only when thermal budget is constrained and peak current remains below 100mA.
MMBT4401-7-F	Higher V_CEO (40V → 60V), same I_C (150mA), but h_FE bin 100–300 and larger SOT-23 package (2.9mm × 1.3mm).	Offers higher voltage headroom but occupies 2.5× more board area; not AEC-Q101 qualified.	Prefer for industrial non-automotive designs where voltage margin >50V is critical and space is less constrained.

Compared with DXT4617R-7 and MMBT4401-7-F, the 2DC4617R-7-F uniquely combines AEC-Q101 qualification, 150mA/50V ratings, tight h_FE bin, and ultra-compact SOT523-making it optimal for space- and reliability-critical automotive signal paths where alternatives trade off size, rating, or qualification.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The 2DC4617R-7-F has an operating junction temperature range of -55°C to +150°C. Under continuous DC conditions at 25°C ambient, its 150mW power dissipation limit and 833°C/W thermal resistance result in a maximum junction temperature of 139.9°C, well within the 150°C absolute maximum rating.

Is the 2DC4617R-7-F compatible with lead-free reflow soldering profiles?

Yes-the device is fully RoHS-compliant and qualified for lead-free reflow soldering. Its matte tin-plated terminals meet MIL-STD-202 Method 208 requirements, and the "Green" molding compound is rated UL 94V-0, supporting standard JEDEC J-STD-020 profile peak temperatures up to 260°C.

How does the h_FE bin R compare to Q and S variants in practical circuit design?

The R-bin (180–390) provides higher and tighter gain than Q-bin (120–270), reducing base drive uncertainty, while offering lower gain variation than S-bin (270–560). This makes R ideal for designs needing predictable saturation with moderate base current, such as 3.3V MCU-driven switches where excessive h_FE could cause unintended partial turn-on.

Can this transistor be used in linear amplifier configurations?

Yes-it supports linear operation with specified f_T ≥140MHz and typical output capacitance of 2–3.5pF. For stable small-signal amplification, use emitter degeneration and ensure V_CE remains ≥1V to avoid saturation; thermal derating must be applied above 25°C ambient due to its 833°C/W R_θJA.
