Product details

Overview

MPSA06_D26Z 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 V_CEO, 100 MHz f_T, and 100 minimum h_FE at 10 mA - commonly used in audio preamplifier stages, signal buffering, and discrete logic-level translation circuits.

For engineers reviewing the MPSA06_D26Z datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (TO-92), confirmed DC and small-signal parameters, thermal derating data, and two validated alternative parts for design continuity and sourcing flexibility.

Technical Context

The MPSA06_D26Z operates as a silicon NPN bipolar junction transistor with a maximum junction temperature of 150°C and specified performance across −55°C to +150°C ambient range. Its 80 V V_CEO and V_CBO ratings support use in medium-voltage analog gain stages and relay drivers.

It exhibits h_FE ≥100 at both IC = 10 mA and IC = 100 mA, with V_CE(sat) ≤ 0.25 V at IC = 100 mA / IB = 10 mA and f_T = 100 MHz under standard test conditions (IC = 10 mA, V_CE = 2.0 V, f = 100 MHz), confirming suitability for audio-frequency amplification and fast-switching digital interface roles.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	80 V - supports operation in 48 V and 60 V rail systems without breakdown risk
I_C (max)	500 mA - enables driving moderate-current loads such as small relays or LED arrays
h_FE	≥100 at IC = 10 mA and IC = 100 mA - ensures stable current gain across common bias points
f_T	100 MHz - sufficient for audio amplification and low-speed digital switching (≤10 MHz)
V_CE(sat)	≤0.25 V at IC = 100 mA / IB = 10 mA - minimizes conduction loss in saturated switch applications
P_D	625 mW at TA = 25°C - defines thermal envelope for TO-92 mounting on standard PCBs
R_θJA	200 °C/W - determines required board copper area and airflow for thermal management

Pinout & Package

Package: TO-92 (3-lead molded plastic), lead-form: straight, standard through-hole mounting. Pin identification follows JEDEC TO-92 outline with emitter (E), base (B), and collector (C) arranged in E–B–C order when viewed from flat side with leads down.

Pin/Terminal	Circuit Role	Design Meaning
E (Emitter)	Current sink terminal	Reference node for bias network; connects to ground or low-impedance return path in common-emitter configurations
B (Base)	Control input	Receives forward-bias current to enable conduction; requires series resistor to limit IB and ensure saturation or linear operation
C (Collector)	Current source terminal	Connects to load and supply rail; carries full output current and dissipates majority of device power in switching mode

Key Features

Feature	Design Value
High V_CEO/V_CBO	80 V rating allows safe operation in industrial control interfaces with transient-prone 24–48 V supplies
Stable h_FE over current range	Minimum 100 gain maintained from 10 mA to 100 mA collector current - simplifies bias design across operating points
Low V_CE(sat)	≤0.25 V at rated drive ensures <125 mW dissipation in saturation - reduces thermal stress in relay/LED driver designs
100 MHz f_T	Supports faithful amplification of audio-band signals (20 Hz–20 kHz) with margin for harmonic content and edge fidelity
−55°C to +150°C T_J	Enables deployment in automotive under-hood, industrial motor control, and outdoor equipment environments

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 package (vs. TO-92); lower P_D (350 mW) and higher R_θJA (357 °C/W); same electrical specs	Preferred for space-constrained PCBs; unsuitable for >200 mA continuous operation without thermal relief	Select MMBTA06 only when footprint reduction is critical and thermal budget permits lower power dissipation.
BC547B	Lower V_CEO (45 V), lower f_T (300 MHz typical but not guaranteed min), h_FE binning varies (110–800)	Acceptable in ≤30 V systems with less stringent gain stability requirements; not recommended for 48 V industrial rails	Choose BC547B only for cost-sensitive consumer-grade designs where 45 V rating and variable h_FE are acceptable.

Compared with MPSA06_D26Z, MMBTA06 offers identical gain and voltage specs in a smaller package but sacrifices thermal capacity, while BC547B trades voltage headroom and guaranteed gain consistency for broader h_FE spread and lower cost - making MPSA06_D26Z the preferred choice for robust 48–60 V industrial signal conditioning.

FAQ

What is the maximum continuous collector current rating for MPSA06_D26Z?

The MPSA06_D26Z has a maximum continuous collector current (I_C) rating of 500 mA at T_A = 25°C. This value decreases with rising ambient temperature per its 5.0 mW/°C thermal derating curve. For sustained operation above 100 mA, PCB copper area and airflow must be evaluated using the 200 °C/W R_θJA specification to avoid exceeding the 150°C maximum junction temperature.

Does MPSA06_D26Z have a guaranteed minimum DC current gain (h_FE)?

Yes, the MPSA06_D26Z guarantees h_FE ≥ 100 at two operating points: IC = 10 mA, V_CE = 1.0 V and IC = 100 mA, V_CE = 1.0 V. This dual-point specification ensures predictable bias stability across both low-current sensing and medium-current switching applications, unlike many general-purpose transistors that only specify h_FE at a single current.

What is the package type and pin configuration of MPSA06_D26Z?

The MPSA06_D26Z uses the TO-92 package with three leads in straight, through-hole configuration. When viewing the flat side of the package with leads pointing downward, the pin order from left to right is Emitter (E), Base (B), Collector (C). This matches JEDEC TO-92 standard orientation and is confirmed in Fairchild's original datasheet Figure 11.

Can MPSA06_D26Z be used in switching applications requiring fast turn-off?

Yes, the MPSA06_D26Z achieves a current gain–bandwidth product (f_T) of 100 MHz, enabling reliable switching up to several megahertz in properly designed circuits. For high-speed switching, minimize base drive impedance and consider adding a reverse-biased Schottky diode across B–E to reduce storage time - though its primary strength remains in audio and medium-speed digital interface roles rather than RF switching.

Is MPSA06_D26Z suitable for automotive under-hood applications?

Yes, the MPSA06_D26Z is rated for junction temperatures from −55°C to +150°C and features robust construction inherited from Fairchild's automotive-qualified process 12. Its 80 V V_CEO, 500 mA I_C, and stable h_FE make it suitable for engine control module signal conditioning, sensor interface buffering, and low-power actuator drivers - provided board-level thermal design meets R_θJA = 200 °C/W requirements.
