Product details

Overview

FJD3076TM from ON Semiconductor is an NPN epitaxial silicon transistor designed for power amplifier and switching applications, featuring 32 V V_CEO, 2 A I_C, 10 W P_C (T_C=25°C), 0.5–0.8 V V_CE(sat) at I_C=2 A/I_B=0.2 A, and 100 MHz f_T; used in audio output stages and DC-DC converter switches.

For engineers reviewing the FJD3076TM datasheet, pinout, applications, or equivalent options, key selection criteria include saturation voltage under high-current drive, safe operating area robustness, thermal dissipation capability in D-PACK package, and DC current gain linearity across 0.5–2 A collector range.

Technical Context

This device operates as a medium-power general-purpose NPN bipolar junction transistor with epitaxial base construction enabling stable h_FE (130–390) and low V_CE(sat). It supports continuous collector currents up to 2 A with junction temperature limited to 150°C and features low output capacitance (50 pF at V_CB=10 V).

The D-PACK surface-mount package provides enhanced thermal performance over TO-252 variants, supporting PCB-mounted heat sinking via the exposed collector tab. Its 100 MHz f_T enables use in audio-frequency amplification and moderate-speed switching up to ~10 MHz.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	32 V - Maximum allowable collector-emitter voltage before breakdown under open-base condition.
I_C	2 A - Continuous DC collector current rating at T_A=25°C; derates above ambient.
V_CE(sat)	0.5–0.8 V - Low saturation voltage ensures minimal conduction loss in switching applications at full load.
h_FE	130–390 - DC current gain range at V_CE=3 V, I_C=0.5 A; supports reliable base drive design.
f_T	100 MHz - Current gain bandwidth product confirms suitability for audio amplification and fast-switching circuits.
C_ob	50 pF - Output capacitance at V_CB=10 V; impacts high-frequency response and switching speed.
P_C (T_C=25°C)	10 W - Maximum power dissipation with case temperature held at 25°C; requires heatsinking for sustained operation.

Pinout & Package

D-PACK (TO-252AA) surface-mount package with exposed collector tab for thermal management; three-terminal configuration: Pin 1 = Base, Pin 2 = Collector (tab), Pin 3 = Emitter.

Pin/Terminal	Circuit Role	Design Meaning
1 (Base)	Control input	Receives forward-biased current to enable transistor conduction; requires current-limiting resistor in driver stage.
2 (Collector)	Power output node	Connected to load or supply rail; electrically and thermally tied to exposed metal tab for efficient heat transfer.
3 (Emitter)	Reference/return path	Serves as common emitter node; typically grounded or connected to low-impedance return path for signal integrity.

Key Features

Feature	Design Value
Low V_CE(sat)	0.5–0.8 V at I_C=2 A/I_B=0.2 A reduces conduction losses and improves efficiency in Class AB amplifiers and switch-mode regulators.
High h_FE range	130–390 at I_C=0.5 A enables simplified base drive circuitry with lower gate/base driver current requirements.
100 MHz f_T	Supports stable small-signal amplification and switching up to audio frequencies without gain roll-off.
D-PACK thermal design	Exposed collector tab allows direct PCB copper pour attachment, achieving lower θ_JA than standard SOT-223 or TO-92 packages.

Alternative Part	Technical Difference	Application Difference	Selection Advice
FJD3076	Identical electrical specs and D-PACK package; underscore replaced by dash per ON Semi nomenclature update.	No functional difference; same pinout, thermal profile, and SOA curve.	Select FJD3076TM for new designs requiring traceable ON Semiconductor branding and updated ordering system compliance.
MJD3076	Same die and specs but in TO-252-2L (non-isolated) variant; identical V_CEO, I_C, V_CE(sat), and f_T.	Lacks isolated mounting option; requires different PCB footprint and thermal pad layout.	Choose MJD3076 only if legacy board reuse or non-isolated thermal interface is acceptable.

FAQ

What is the maximum continuous collector current rating for the FJD3076TM?

The FJD3076TM has a maximum continuous collector current (I_C) of 2 A at ambient temperature (T_A=25°C). This rating assumes adequate PCB copper area for heat dissipation; derating applies above 25°C ambient or when case temperature exceeds 25°C. For sustained 2 A operation, thermal design must maintain T_C ≤25°C to leverage the full 10 W power dissipation capability. The FJD3076TM datasheet specifies this limit under defined test conditions and must be validated in the final application layout.

Does the FJD3076TM have a built-in diode or protection feature?

No, the FJD3076TM is a discrete NPN bipolar junction transistor without integrated protection diodes, ESD structures, or thermal shutdown. It relies on external circuitry-such as flyback diodes across inductive loads or base-emitter clamping resistors-for safe operation. The device exhibits standard BJT characteristics including 5 V V_EB0 and 1 µA I_EBO, but no internal protection is specified in the FJD3076TM datasheet or ON Semiconductor documentation.

What is the pin configuration of the FJD3076TM in the D-PACK package?

The FJD3076TM uses a D-PACK (TO-252AA) package with three terminals: Pin 1 is the Base, Pin 2 is the Collector (connected to the exposed metal tab), and Pin 3 is the Emitter. This configuration is standardized across ON Semiconductor's D-PACK transistors and matches the mechanical outline in the FJD3076TM datasheet Rev. C1. The exposed collector tab must be soldered to a thermal pad for optimal power handling.

Can the FJD3076TM replace the older FJD3076 part in existing designs?

Yes, the FJD3076TM is functionally and mechanically identical to the FJD3076, differing only in nomenclature to comply with ON Semiconductor's post-Fairchild integration naming convention (underscore → dash). Electrical specifications, package dimensions, pinout, and thermal performance are fully aligned. The FJD3076TM is intended as the direct successor and drop-in replacement for FJD3076 in all applications supported by the original part.

What is the safe operating area (SOA) limitation for the FJD3076TM at 100 µs pulse width?

Per the FJD3076TM datasheet Figure 6, the single nonrepetitive pulse SOA at PW=100 µs supports up to ~8 A collector current at V_CE=10 V, constrained by secondary breakdown limits-not just thermal or current limits. This pulse rating assumes T_C=25°C and proper gate/base drive to avoid localized hot spots. Designers must verify transient stress in the actual circuit using the published SOA curves, as the FJD3076TM does not include internal SOA protection circuitry.
