Product details

Overview

2DC4617S-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 thermal resistance. It delivers h_FE = 270–560 at V_CE = 6V, I_C = 1mA, with f_T = 140–180MHz and V_CE(SAT) ≤ 0.4V at I_C = 50mA/I_B = 5mA - used in compact automotive signal switching and low-power amplifier stages.

For engineers reviewing the 2DC4617S-7-F datasheet, 2DC4617S-7-F pinout, 2DC4617S-7-F application, or 2DC4617S-7-F equivalent, key selection criteria include AEC-Q101 qualification, ultra-small SOT523 footprint, DC gain binning (S-grade), ESD robustness (4kV HBM), and thermal derating behavior above 25°C ambient.

Technical Context

This NPN transistor operates as a general-purpose amplifying and switching device with verified breakdown ratings: V_CEO = 50V, V_CBO = 60V, V_EBO = 7V. Its gain-bandwidth product spans 140–180MHz depending on bias and frequency test conditions, supporting RF front-end and high-speed digital interface applications up to ~100MHz.

Thermal performance is defined by R_θJA = 833°C/W on 1oz FR4, with linear power derating above 25°C ambient. ESD protection meets JEDEC Class 3A (4000V HBM, 400V MM), confirming suitability for automated assembly and automotive module environments.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - Maximum safe collector-emitter voltage before avalanche conduction in common-emitter configuration.
I_C (max)	150 mA - Continuous collector current limit defining usable drive capability in switching or amplification.
P_D (T_A=25°C)	150 mW - Steady-state power handling on standard PCB layout; derates linearly above 25°C.
h_FE (S-grade)	270–560 - DC current gain range at V_CE = 6V, I_C = 1mA; enables predictable biasing in linear circuits.
f_T	140–180 MHz - Frequency where small-signal current gain drops to unity; sets upper bound for RF amplification.
V_CE(SAT)	≤ 0.4 V - Saturation voltage at I_C = 50mA/I_B = 5mA; determines on-state power loss in switch mode.
ESD HBM	4000 V - Human Body Model rating per JESD22-A114; supports robust handling in production lines.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Emitter terminal	Reference node for current flow; connects to ground or low-impedance return path in common-emitter topology.
2 (Base)	Control input	Receives bias current to modulate collector current; requires series resistor for stable DC operation.
3 (Collector)	Output current node	Delivers amplified or switched current to load; connected to supply rail via pull-up or active driver.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive temperature (-55°C to +150°C) and reliability stress testing per JESD47.
SOT523 footprint	1.6mm × 1.6mm body size enables high-density PCB layouts in space-constrained modules.
Green compound	Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb) compliant with RoHS 3.

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
2DC4617R-7-F	Lower h_FE range (180–390) and same package/ratings.	Suitable where gain tolerance >±30% is acceptable and cost optimization is prioritized.	Select when circuit gain stability requirements are relaxed and BOM cost reduction is critical.
MMBT3904-7-F	Same SOT23 package (not SOT523); h_FE = 100–300; lower f_T (300MHz typical but not guaranteed at 100MHz).	Requires PCB redesign due to larger footprint; less suitable for ultra-dense automotive modules.	Choose only if SOT23 layout exists and higher thermal resistance (R_θJA ≈ 300°C/W) is acceptable.

Compared with 2DC4617R-7-F, the S-grade offers tighter h_FE control for precision biasing; versus MMBT3904-7-F, it provides smaller footprint and guaranteed high-frequency performance at 100MHz, critical for modern compact designs.

FAQ

What is the maximum operating temperature for 2DC4617S-7-F?

The device supports junction and storage temperatures from –55°C to +150°C per datasheet DS30252 Rev. 10–2. Its thermal resistance (R_θJA = 833°C/W) defines how much ambient temperature rise occurs per milliwatt dissipated on a standard 1oz FR4 PCB. Derating begins immediately above 25°C ambient.

Is 2DC4617S-7-F pin-compatible with other SOT523 transistors?

Yes - all SOT523-packaged NPN transistors share identical pinout (Emitter-Base-Collector on pins 1-2-3). However, electrical parameters like h_FE, V_CE(SAT), and f_T vary significantly between part numbers; direct substitution requires validation against circuit bias and frequency requirements.

Does 2DC4617S-7-F support lead-free reflow soldering?

Yes - it features matte tin-plated leads qualified per MIL-STD-202, Method 208, and is fully RoHS 3 compliant (EU Directive 2015/863/EU). The "Green" molding compound meets UL 94V-0 flammability rating and is halogen/antimony free per Diodes' specification.

How does the S-grade h_FE bin differ from Q and R variants?

The S-grade guarantees h_FE = 270–560 at V_CE = 6V, I_C = 1mA - a wider but higher minimum than R-grade (180–390) and Q-grade (120–270). This enables more predictable DC bias in amplifier stages where gain consistency across temperature and unit variance is critical.
