Product details

Overview

2PC4617S,115 from Nexperia is an NPN general-purpose bipolar junction transistor in SOT416 (SC-75) package, rated for 50 V V_CEO, 150 mA I_C, and 150 mW P_tot, with DC current gain h_FE of 270–560 at I_C = 1 mA, used in low-power switching and amplification circuits in consumer electronics and EDP systems.

For engineers reviewing the 2PC4617S,115 datasheet, 2PC4617S,115 pinout, 2PC4617S,115 application, or 2PC4617S,115 equivalent, key selection criteria include its SC-75 footprint compatibility, low-voltage/low-current operation, verified h_FE range, thermal resistance of 833 K/W, and complementary PNP pairing with 2PA1774.

Technical Context

This discrete NPN transistor operates in linear and saturation regions with V_CE(sat) ≤ 200 mV at I_C = 50 mA / I_B = 5 mA and f_T ≥ 100 MHz, enabling use in RF-coupled preamplifiers and digital logic interface stages. Its 1.5 pF collector capacitance supports stable high-frequency bias networks.

Designed for surface-mount assembly on FR4 PCBs with single-sided copper, it exhibits T_j up to 150 °C and R_th(j-a) = 833 K/W under standard footprint conditions-critical for thermally constrained portable designs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - Maximum safe collector-emitter voltage with base open; defines upper rail limit in low-voltage switching stages.
I_C (DC)	150 mA - Continuous collector current handling; suitable for driving LEDs, small relays, or logic-level signal buffering.
h_FE	270–560 - DC current gain at I_C = 1 mA, V_CE = 6 V; enables predictable base drive sizing in amplifier and switch designs.
V_CE(sat)	≤200 mV - Low saturation voltage at I_C = 50 mA / I_B = 5 mA; minimizes power loss and self-heating in saturated-switch applications.
f_T	≥100 MHz - Transition frequency at I_C = 2 mA, V_CE = 12 V; supports audio and low-MHz RF amplification without gain roll-off.
R_th(j-a)	833 K/W - Junction-to-ambient thermal resistance on FR4; informs derating curves for ambient temperatures above 25 °C.

Pinout & Package

SOT416 (SC-75) plastic surface-mounted package: ultra-small outline, 3-pin, single-ended lead frame, 1.75 mm × 0.95 mm footprint, 0.45 mm height, optimized for space-constrained portable PCBs.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Current-controlled input node; requires series resistor to limit I_B ≤ 200 mA peak per datasheet limiting values.
2	Emiter	Common reference terminal in common-emitter configuration; connected to ground or low-impedance return path.
3	Collector	Output current sink node; connects to load (e.g., LED anode or relay coil) and positive supply via pull-up.

Key Features

Feature	Design Value
Low-voltage operation	V_CEO = 50 V and V_EBO = 7 V enable safe use in 3.3 V, 5 V, and 12 V logic-supplied circuits without overvoltage risk.
High DC current gain	h_FE = 270–560 reduces required base drive current, lowering MCU GPIO loading and improving system power efficiency.
Ultra-compact packaging	SOT416 (SC-75) footprint saves >60% board area vs. SOT23, critical for wearables and miniaturized consumer modules.
Controlled saturation behavior	V_CE(sat) ≤ 200 mV ensures minimal voltage drop across collector-emitter during switching, preserving output headroom.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC846B,215	V_CEO = 65 V, h_FE = 200–450, same SOT23 package (larger than SOT416)	Higher voltage rating but larger footprint; not a drop-in replacement due to package mismatch	Select when board layout allows SOT23 and higher V_CEO margin is needed
MMBT3904LT1G	V_CEO = 40 V, h_FE = 100–300, SOT23 package	Lower voltage and gain; requires recalculation of base resistor for same I_C	Choose only if cost sensitivity outweighs performance and size requirements

Compared with BC846B,215 and MMBT3904LT1G, the 2PC4617S,115 delivers superior gain consistency and smallest PCB footprint among these three, making it optimal for space-constrained, low-voltage, medium-gain switching where thermal dissipation is managed via layout.

FAQ

What is the maximum continuous collector current for the 2PC4617S,115?

The 2PC4617S,115 has a maximum DC collector current (I_C) of 150 mA, as specified in Table 4 of its datasheet under limiting values. This rating applies at T_amb ≤ 25 °C with proper PCB thermal design. Derating is required above this ambient temperature, guided by its R_th(j-a) of 833 K/W. Exceeding 150 mA risks thermal runaway or permanent degradation of the 2PC4617S,115.

Does the 2PC4617S,115 have a PNP complement, and what is its part number?

Yes, the PNP complement of the 2PC4617S,115 is the 2PA1774, explicitly stated in section 1.1 of the product profile. Both devices share matching voltage ratings, current capabilities, and SOT416 packaging, enabling balanced push-pull or differential pair implementations. The 2PA1774 is documented as a direct functional counterpart-not a generic alternative-to the 2PC4617S,115.

What is the DC current gain (h_FE) range for the 2PC4617S,115 at typical operating conditions?

The 2PC4617S,115 exhibits a DC current gain (h_FE) of 270 to 560 when measured at I_C = 1 mA and V_CE = 6 V, per Table 6 in the datasheet. This range reflects device-to-device variation within the 2PC4617S,115 production lot and must be accounted for in base resistor calculations. It is higher than the 2PC4617Q and 2PC4617R variants, confirming the 2PC4617S,115 as the highest-gain version in the family.

Can the 2PC4617S,115 be used in RF applications, and what is its transition frequency?

Yes, the 2PC4617S,115 supports RF applications up to its transition frequency (f_T) of ≥100 MHz, measured at I_C = 2 mA and V_CE = 12 V. Its 1.5 pF collector capacitance and low parasitic inductance from the SOT416 package contribute to stable high-frequency response. While not intended for power RF, the 2PC4617S,115 is suitable for low-power RF preamplifiers, oscillator biasing, and IF signal conditioning stages.

What marking code identifies the 2PC4617S,115 on the physical device?

The 2PC4617S,115 is marked with the code "ZS" on its top surface, as confirmed in Table 3 of the datasheet under Marking Codes. This laser-etched or molded marking distinguishes it from other variants: 2PC4617Q uses "ZQ", and 2PC4617R uses "ZR". Visual inspection of the "ZS" marking is a reliable method to verify authenticity and variant identity of the 2PC4617S,115.
