Product details
Overview
2DC4617Q-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, used in compact automotive signal switching and biasing circuits compliant with AEC-Q101.
For engineers reviewing the 2DC4617Q-7-F datasheet, 2DC4617Q-7-F pinout, 2DC4617Q-7-F application, or 2DC4617Q-7-F equivalent, key selection criteria include VCEO = 50V, hFE = 120–270 (at IC = 1mA), VCE(SAT) ≤ 0.4V (IC = 50mA, IB = 5mA), fT = 140MHz, and ESD HBM rating of 4000V.
Technical Context
This NPN transistor operates as a general-purpose amplifying and switching device with verified breakdown ratings: VCBO = 60V, VCEO = 50V, VEBO = 7V. Its DC current gain is binned per variant-Q grade offers hFE = 120–270-and it delivers fT = 140MHz at VCE = 12V, IC = 2mA, enabling mid-frequency analog and digital interface functions.
Thermally, it sustains operation from −55°C to +150°C with RθJA = 833°C/W on standard 1oz FR4 PCB layout. Its ultra-small SOT523 footprint (1.6 × 1.6 mm) supports high-density placement while maintaining 4000V HBM ESD robustness and full AEC-Q101 qualification for automotive under-hood signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage before avalanche conduction in common-emitter configuration |
| IC (max) | 150 mA - Continuous collector current handling capacity without thermal runaway on standard PCB |
| PD | 150 mW - Steady-state power dissipation limit at TA = 25°C with derating above 25°C |
| hFE | 120–270 - DC current gain range at VCE = 6V, IC = 1mA, defining base drive sensitivity |
| fT | 140 MHz - Frequency at which short-circuit current gain drops to unity, indicating usable bandwidth |
| VCE(SAT) | ≤0.4 V - Saturation voltage at IC = 50mA / IB = 5mA, determining low-loss switching efficiency |
| ESD HBM | 4000 V - Human Body Model withstand level, supporting robust handling in automotive assembly lines |
Pinout & Package
SOT523 is a 3-pin ultra-miniature surface-mount plastic package measuring 1.60 × 1.60 × 0.75 mm (L × W × H), with matte tin-plated leads solderable per MIL-STD-202 Method 208 and moisture sensitivity level 1 per J-STD-020.

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 |
|---|---|---|---|
| BC847BW,115 | Same SOT-323 package; hFE = 110–220; VCEO = 45V; not AEC-Q101 qualified | Limited to commercial-grade consumer electronics; unsuitable for automotive under-hood use | Select only if AEC-Q101 compliance is unnecessary and lower VCEO suffices |
| MMBT3904LT1G | SOT-23 package; hFE = 100–300; VCEO = 40V; AEC-Q101 qualified but larger footprint (2.9 × 1.3 mm) | Acceptable for board space-constrained industrial controls where SOT-23 is already standardized | Choose when legacy SOT-23 layout reuse outweighs size advantage of SOT523 |
Compared with BC847BW and MMBT3904LT1G, the 2DC4617Q-7-F uniquely combines AEC-Q101 qualification, 50V VCEO, and SOT523 miniaturization-enabling next-gen automotive modules where both reliability and PCB area are critical constraints.

FAQ
What is the maximum operating temperature for 2DC4617Q-7-F?
The device operates from −55°C to +150°C for both junction and storage temperatures. Its thermal resistance of 833°C/W means ambient temperature must be limited to approximately 85°C to maintain safe junction temperature at full 150mW dissipation on standard PCB layout.
Is 2DC4617Q-7-F pin-compatible with other SOT523 transistors?
Yes-it follows standard SOT523 pinout: Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector. This matches industry-standard orientation and is mechanically compatible with automated pick-and-place equipment calibrated for SOT523 footprints.
How does the hFE binning work across 2DC4617Q/R/S variants?
The Q variant has hFE = 120–270, R = 180–390, and S = 270–560, all tested at VCE = 6V and IC = 1mA. This binning allows designers to select gain consistency for specific circuit requirements-e.g., Q for moderate-gain switching, S for high-gain amplification.
Can 2DC4617Q-7-F replace a generic 2N3904 in existing designs?
No direct drop-in replacement: 2DC4617Q-7-F uses SOT523 (1.6 × 1.6 mm), while 2N3904 is TO-92. Electrical specs differ-VCEO is higher (50V vs. 40V), but IC max is lower (150mA vs. 200mA). Layout redesign and validation are required for migration.
