Product details

Overview

2DC4617S-7 from Diodes Incorporated is a 50V NPN small-signal transistor in SOT523 package, rated for 150mA continuous collector current, 150mW power dissipation, and featuring h_FE = 270–560 (V_CE = 6V, I_C = 1mA). It delivers high-voltage switching and amplification in space-constrained automotive sensor interfaces and portable power management circuits.

For engineers reviewing the 2DC4617S-7 datasheet, 2DC4617S-7 pinout, 2DC4617S-7 application, or 2DC4617S-7 equivalent, key selection criteria include V_CEO = 50V, h_FE binning (S-grade), ESD HBM = 4000V, thermal resistance R_θJA = 833°C/W, and AEC-Q101 qualification for automotive reliability.

Technical Context

This NPN bipolar junction transistor operates as a general-purpose amplifier or switch with fixed-emitter biasing capability. Its 7V V_EBO rating supports robust base drive margin, while f_T = 140–180MHz enables RF-coupled signal conditioning up to low-UHF frequencies.

The device uses a planar epitaxial die structure with matte tin-plated leads and conforms to J-STD-020 Level 1 moisture sensitivity. Thermal derating begins at 25°C ambient, with linear power reduction to zero at 150°C junction temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50V - Supports switching of 24V automotive rails with 100% safety margin
I_C (max)	150mA - Drives medium-current loads like LED indicators or relay coils
h_FE (min–max)	270–560 - Enables stable DC biasing across temperature without external feedback
P_D	150mW - Limits usable continuous power in SOT523 without heatsinking
f_T	140–180MHz - Suitable for IF amplification in AM/FM receivers and sensor front-ends
ESD HBM	4000V - Reduces risk of handling damage during manual assembly or test
AEC-Q101	Qualified - Meets stress-test requirements for automotive under-hood electronics

Pinout & Package

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
BC847BS,115	h_FE = 200–450 (lower max gain); SOT363 package (dual device)	Designed for dual-transistor configurations; lacks AEC-Q101 qualification	Select when dual-device integration reduces component count and automotive qualification is not required
MMBT3904LT1G	h_FE = 100–300 (narrower range); SOT23 package (larger footprint)	Higher R_θJA = 350°C/W; no AEC-Q101 or ESD HBM ≥4000V rating	Choose for cost-sensitive consumer designs where thermal performance and ESD robustness are secondary

Compared with BC847BS,115 and MMBT3904LT1G, the 2DC4617S-7 provides higher gain consistency, superior ESD immunity, and automotive-grade reliability in the smallest available footprint-making it optimal for space- and reliability-critical embedded systems.

FAQ

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

The 2DC4617S-7 has an absolute maximum junction temperature of +150°C and a storage temperature range of –55°C to +150°C. Derating begins at 25°C ambient, with power dissipation linearly reduced to zero at 150°C junction temperature per the thermal resistance curve (R_θJA = 833°C/W).

How does the h_FE binning differ between 2DC4617Q, R, and S variants?

The 2DC4617Q, R, and S suffixes denote h_FE bins: Q = 120–270, R = 180–390, S = 270–560 (measured at V_CE = 6V, I_C = 1mA). The S-grade offers highest minimum gain, enabling tighter bias stability in precision amplifier or low-current switch designs.

Is 2DC4617S-7 compatible with lead-free reflow soldering processes?

Yes. The 2DC4617S-7 features matte tin-plated leads compliant with MIL-STD-202, Method 208, and is qualified for lead-free reflow per J-STD-020 Level 1 (MSL-1). Its UL 94V-0 molding compound withstands peak reflow temperatures up to 260°C.

Can 2DC4617S-7 replace MMBT3904 in existing designs?

Direct replacement is possible only if layout accommodates SOT523 (vs. SOT23), and if h_FE ≥270 and AEC-Q101 qualification are required. Electrical parameters align closely, but thermal performance differs significantly (R_θJA = 833°C/W vs. ~350°C/W), requiring verification of power dissipation margins in the target application.
