Product details

Overview

MPS6513_D74Z from Fairchild Semiconductor is an NPN general-purpose bipolar junction transistor (BJT) designed for amplification and switching applications, with a 30 V V_CEO, 200 mA I_C, and 100 MHz f_T bandwidth, commonly used in low-power audio preamplifiers, signal conditioning stages, and discrete logic-level switching circuits.

For engineers reviewing the MPS6513_D74Z datasheet, pinout, applications, or equivalent options, key selection criteria include DC current gain (h_FE = 90–180 at I_C = 2 mA), V_CE(sat) ≤ 0.5 V at I_C = 50 mA/I_B = 5 mA, thermal resistance (R_θJA = 200 °C/W), and TO-92 package compatibility in space-constrained analog designs.

Technical Context

The MPS6513_D74Z operates as a silicon NPN BJT fabricated using Process 23, supporting dual-mode use: linear amplification up to 100 MHz and saturated switching up to 100 mA DC collector current. Its base-emitter junction is rated for 4 V reverse bias, and it maintains stable h_FE across I_C = 2–100 mA at V_CE = 10 V.

Thermal performance is defined for mounting on a standard FR-4 PCB (1.6" × 1.6" × 0.06"), with R_θJC = 83.3 °C/W and R_θJA = 200 °C/W. Maximum junction temperature is 150 °C, and operating ambient range spans −55 °C to +150 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	30 V - Maximum safe collector-emitter voltage before breakdown under open-base conditions.
I_C (DC)	200 mA - Continuous collector current rating; supports moderate-power switching without forced cooling.
h_FE	90–180 - DC current gain range at V_CE = 10 V, enabling predictable base drive sizing for amplifier or switch biasing.
V_CE(sat)	≤ 0.5 V - Low saturation voltage at I_C = 50 mA/I_B = 5 mA, minimizing conduction loss in switching applications.
f_T	100 MHz - Transition frequency indicating usable small-signal amplification bandwidth up to RF front-end or wideband analog stages.
C_ob	3.5 pF - Output capacitance at V_CB = 5 V, influencing high-frequency stability and impedance matching in tuned circuits.

Pinout & Package

Package: TO-92 - Three-lead through-hole plastic package with standard lead spacing (0.1" pitch), optimized for manual assembly and prototyping in low-voltage analog boards.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current sink terminal	Reference node for bias network; connects to ground or low-impedance return path in common-emitter configurations.
2 (Base)	Control input	Receives current-limited drive signal; requires series resistor to limit I_B and ensure proper h_FE-based I_C scaling.
3 (Collector)	Current source terminal	Connects to load or supply rail; carries amplified/saturated output current with minimal V_CE(sat) drop.

Key Features

Feature	Design Value
General-purpose NPN architecture	Enables reuse across amplification, switching, and level-shifting functions without redesigning bias networks.
100 MHz transition frequency (f_T)	Supports audio and low-RF signal amplification without external compensation in single-stage CE topologies.
Low V_CE(sat) (≤ 0.5 V)	Reduces power dissipation during on-state operation, improving efficiency in battery-powered or thermally constrained switches.
Wide h_FE range (90–180)	Allows robust circuit operation across process variation and temperature drift without active feedback stabilization.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN general-purpose amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC547B	V_CEO = 45 V, h_FE = 200–450 (higher gain, wider spread), R_θJA = 200 °C/W (same)	Better suited for higher-voltage amplification; less consistent gain control in switching due to wider h_FE range	Select BC547B when V_CEO margin > 15 V is required and tighter V_CE(sat) tolerance is not critical
2N3904	V_CEO = 40 V, I_C = 200 mA, f_T = 300 MHz (higher bandwidth), C_ob = 4.0 pF	Superior high-frequency response but higher output capacitance; slightly lower V_CE(sat) (0.2 V typical)	Choose 2N3904 for RF amplifier stages > 100 MHz or where faster switching edges are prioritized over thermal margin

Compared with BC547B and 2N3904, the MPS6513_D74Z offers balanced trade-offs: mid-range f_T and h_FE stability ideal for cost-sensitive, thermally constrained audio and logic interfaces where predictable saturation behavior and manufacturability in TO-92 are essential.

FAQ

What is the maximum continuous collector current rating for the MPS6513_D74Z?

The MPS6513_D74Z has a maximum DC collector current (I_C) rating of 200 mA, verified per its Absolute Maximum Ratings table at T_C = 25 °C. This rating assumes adequate PCB copper area for heat dissipation; derating applies above 25 °C at 5.0 mW/°C. The MPS6513_D74Z must not exceed this limit in sustained operation to avoid thermal runaway or permanent degradation.

Does the MPS6513_D74Z support high-frequency amplification, and up to what frequency?

Yes, the MPS6513_D74Z supports small-signal amplification up to 100 MHz, as specified by its transition frequency (f_T) in the Electrical Characteristics table. This makes it suitable for audio band and low-RF applications such as IF amplifiers or oscillator buffer stages, provided layout parasitics are minimized. The MPS6513_D74Z achieves this while maintaining stable h_FE and low output capacitance (C_ob = 3.5 pF).

What is the typical saturation voltage of the MPS6513_D74Z under switching conditions?

The MPS6513_D74Z exhibits a typical collector-emitter saturation voltage (V_CE(sat)) of ≤ 0.5 V when operated with I_C = 50 mA and I_B = 5 mA, per the datasheet's Electrical Characteristics table. This low V_CE(sat) ensures minimal conduction loss in switching applications. The MPS6513_D74Z maintains this performance across its specified temperature range, supporting efficient discrete switch design.

Is the MPS6513_D74Z packaged in a TO-92 case, and are pin assignments standardized?

Yes, the MPS6513_D74Z uses the industry-standard TO-92 package with lead configuration: Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector. This pinout is confirmed in the device's mechanical drawing and absolute maximum ratings section. The MPS6513_D74Z shares identical footprint and soldering requirements with other TO-92 NPN transistors, enabling direct board-level substitution where electrical specs align.

What is the operating junction temperature range for the MPS6513_D74Z?

The MPS6513_D74Z supports an operating and storage junction temperature range of −55 °C to +150 °C, as stated in its Absolute Maximum Ratings. This wide range enables deployment in automotive under-hood, industrial control, and outdoor equipment environments. The MPS6513_D74Z achieves this with a maximum junction temperature limit of 150 °C, enforced via thermal resistance values (R_θJA = 200 °C/W) under defined PCB mounting conditions.
