Product details

Overview

MPSA06_D27Z from ON Semiconductor is an NPN general-purpose amplifier transistor designed for low-to-medium power linear and switching applications up to 500 mA collector current, with 80 V collector-emitter breakdown voltage and 100 MHz gain-bandwidth product, commonly used in audio preamplifier stages, signal buffering, and discrete logic interface circuits.

For engineers reviewing the MPSA06_D27Z datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, TO-92 package mapping, thermal derating data, and validated alternative transistors for amplifier design, BOM replacement, and legacy Fairchild migration scenarios.

Technical Context

The MPSA06_D27Z operates as a silicon NPN bipolar junction transistor optimized for general-purpose amplification with DC current gain (h_FE) ≥100 at both 10 mA and 100 mA collector currents, and exhibits low saturation voltage (V_CE(sat) ≤ 0.25 V at I_C = 100 mA, I_B = 10 mA) and moderate input capacitance for stable small-signal performance.

Its thermal design supports 625 mW total dissipation at 25°C ambient with 5.0 mW/°C derating, and junction temperature range spans −55°C to +150°C - enabling use in industrial control modules and automotive under-hood auxiliary circuits where ambient temperatures exceed 85°C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	80 V - Maximum safe collector-emitter voltage before avalanche breakdown; enables use in 48 V supply rails and flyback snubber circuits.
I_C Continuous	500 mA - Sustained collector current capability; supports driver-stage operation for relays, LEDs, and small solenoids.
h_FE	≥100 at I_C = 10 mA and I_C = 100 mA - Predictable DC gain across two decades of operating current; simplifies bias network design.
f_T	100 MHz - Current gain–bandwidth product; suitable for audio amplification (≤20 kHz) and low-speed digital signal conditioning.
V_CE(sat)	≤0.25 V at I_C = 100 mA, I_B = 10 mA - Low saturation voltage reduces conduction loss and self-heating in switching applications.
P_D	625 mW at T_A = 25°C - Power handling on standard FR-4 PCB; requires thermal relief for sustained >300 mA operation.
R_θJA	200 °C/W - Junction-to-ambient thermal resistance in TO-92 package; informs heatsinking requirements for continuous duty.

Pinout & Package

Package: TO-92 3L molded plastic case with straight leads; standardized mechanical footprint per JEDEC TO-92 specification; lead finish is matte tin over nickel.

Pin/Terminal	Circuit Role	Design Meaning
E (Emitter)	Current sink terminal	Reference node for base biasing; connected to ground or low-impedance return path in common-emitter configurations.
B (Base)	Control input	Receives forward-biased current to modulate collector current; requires series resistor to limit drive current and prevent thermal runaway.
C (Collector)	Current source terminal	Delivers amplified output current; connected to load and positive supply; must be rated for full V_CEO and I_C stress.

Key Features

Feature	Design Value
General-purpose amplifier optimization	Validated h_FE ≥100 across 10–100 mA range ensures consistent gain in both small-signal and medium-current stages without re-biasing.
High V_CEO / V_CBO	80 V rating allows direct interfacing with 24 V and 48 V industrial control buses without external clamping components.
Low V_CE(sat)	0.25 V max at 100 mA enables <100 mW conduction loss in switching mode - critical for thermally constrained PCB layouts.
Wide operating temperature range	−55°C to +150°C junction range supports deployment in unheated outdoor enclosures and engine bay electronics.
TO-92 compatibility	Standardized pinout (E-B-C, viewed from flat side) ensures drop-in replacement for legacy MPSA06 variants in existing through-hole designs.

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
MMBTA06	SOT-23 surface-mount package; lower P_D (350 mW) and higher R_θJA (357 °C/W); same V_CEO, h_FE, and f_T.	Used in space-constrained PCBs where automated assembly and board density outweigh thermal margin needs.	Select MMBTA06 when migrating to SMT layout and thermal management is handled via copper pour or airflow.
PZTA06	SOT-223 package with integrated heat tab; higher P_D (1000 mW) and lower R_θJA (125 °C/W); identical electrical specs.	Preferred in thermally demanding environments like motor control feedback paths or high-duty-cycle switching.	Choose PZTA06 when continuous collector current exceeds 300 mA and board-level heatsinking is limited.

Compared with MPSA06_D27Z, MMBTA06 offers footprint reduction at the cost of thermal headroom, while PZTA06 delivers superior power handling in a larger surface-mount format - all three share identical gain, voltage, and frequency characteristics, enabling functionally aligned selection based on mechanical and thermal constraints.

FAQ

What is the pin configuration of the MPSA06_D27Z?

The MPSA06_D27Z uses a TO-92 package with Emitter–Base–Collector (E-B-C) pinout when viewed from the flat side with leads pointing downward. Pin 1 is Emitter, Pin 2 is Base, and Pin 3 is Collector - matching JEDEC-standard orientation for direct compatibility with legacy MPSA06 footprints and schematics.

Does the MPSA06_D27Z support switching applications?

Yes, the MPSA06_D27Z supports switching applications due to its low V_CE(sat) of ≤0.25 V at I_C = 100 mA and fast transition times enabled by its 100 MHz f_T. It is routinely used to drive relays, LEDs, and small solenoids in industrial control systems where moderate speed and robust saturation are required.

What is the maximum operating temperature for the MPSA06_D27Z?

The MPSA06_D27Z has a specified junction temperature range of −55°C to +150°C. Its thermal resistance (R_θJA = 200 °C/W) means that at 25°C ambient and 500 mW dissipation, junction temperature reaches approximately 125°C - well within safe limits for continuous operation in most industrial environments.

Is the MPSA06_D27Z RoHS compliant?

Yes, the MPSA06_D27Z is RoHS compliant and meets the EU Directive 2011/65/EU requirements. ON Semiconductor confirms lead-free matte tin plating on TO-92 leads and halogen-free molding compound, with full compliance documentation available upon request for production traceability.

How does the MPSA06_D27Z differ from the original Fairchild MPSA06?

The MPSA06_D27Z is the ON Semiconductor–branded continuation of the Fairchild MPSA06 after the 2016 acquisition. Electrical specifications, TO-92 package dimensions, pinout, and absolute maximum ratings are identical; only branding, part numbering convention (underscore → dash), and documentation branding have changed - ensuring full functional and mechanical interchangeability.
