Product details
Overview
MPSA05_D75Z from ON Semiconductor is an NPN general-purpose amplifier transistor rated for 60 V VCEO, 500 mA IC, and 625 mW PD in TO-92 package, designed for linear amplification and switching at collector currents up to 300 mA in discrete analog stages of power supplies, signal conditioning circuits, and interface drivers.
For engineers reviewing the MPSA05_D75Z datasheet, pinout, applications, or equivalent options, key selection criteria include its 100 MHz fT, 100 minimum hFE at 10 mA, VCE(sat) ≤ 0.25 V at IC/IB = 100 mA/10 mA, and −55°C to +150°C operating temperature range - all critical for stable low-to-mid-power amplification and saturated switching designs.
Technical Context
The MPSA05_D75Z is a silicon NPN bipolar junction transistor fabricated using Fairchild's Process 10, optimized for general-purpose linear amplification with guaranteed DC current gain (hFE) ≥100 at both 10 mA and 100 mA collector current, supporting consistent biasing across wide dynamic ranges.
It features a 60 V breakdown rating for both VCEO and VCBO, 4.0 V VEBO, and ultra-low leakage (ICEO ≤ 0.1 μA), enabling reliable operation in medium-voltage analog front-ends and discrete driver stages where voltage margin and thermal stability are essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 60 V - supports operation in 48 V and lower rail systems with safety margin against transients |
| IC | 500 mA - enables driving moderate loads such as relay coils, LED arrays, or pre-driver stages |
| fT | 100 MHz - sufficient for audio amplification and low-speed digital switching up to ~10 MHz |
| hFE | ≥100 at IC = 10 mA and IC = 100 mA - ensures predictable DC bias stability across operating current range |
| VCE(sat) | ≤0.25 V at IC/IB = 100 mA/10 mA - minimizes conduction loss in saturated switch applications |
| PD | 625 mW at TA = 25°C - defines maximum continuous power dissipation on standard FR-4 PCB without heatsink |
Pinout & Package
Package: TO-92 (3-lead molded plastic), straight or bent lead form, compatible with through-hole assembly and manual prototyping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current exit path from transistor | Connected to ground or low-side reference; determines emitter-follower or common-emitter configuration |
| 2 (Base) | Control terminal for minority carrier injection | Receives drive current to modulate collector current; requires current-limiting resistor in most applications |
| 3 (Collector) | Current entry path into transistor | Connected to load and supply rail; carries full switched/amplified current and dissipates majority of heat |
Key Features
| Feature | Design Value |
|---|---|
| High DC current gain consistency | hFE ≥100 at both 10 mA and 100 mA - simplifies bias network design across load variations |
| Low saturation voltage | VCE(sat) ≤ 0.25 V - reduces power loss and self-heating during switching duty cycles |
| Wide operating temperature range | −55°C to +150°C - supports deployment in industrial environments without derating penalties |
| Low leakage performance | ICEO ≤ 0.1 μA at VCE = 60 V - maintains off-state integrity in high-impedance bias networks |
Applications
| Audio Pre-Amplifier Stage | DC Motor Speed Control Driver |
|---|---|
|
Use Scenario: Amplifying line-level signals before op-amp buffering or ADC input in consumer audio equipment. IC Role / Device Role / Timing Role: Discrete NPN amplifier in common-emitter configuration with fixed bias or emitter degeneration. Use Value: 100 MHz fT and ≥100 hFE ensure flat frequency response up to 20 kHz and minimal distortion at 1–10 mA quiescent current. |
Use Scenario: Switching PWM-controlled current to small brushed DC motors in robotics or actuator modules. IC Role / Device Role / Timing Role: Saturated switch controlling motor winding current via base-driven on/off control. Use Value: VCE(sat) ≤ 0.25 V at 100 mA reduces conduction loss, while 60 V VCEO accommodates back-EMF spikes up to 40 V. |

|
Use Scenario: Constant-current drive for indicator or status LEDs in industrial HMIs and panel meters. IC Role / Device Role / Timing Role: Emitter-follower configured transistor regulating LED current via base voltage reference.

Use Scenario: Level-shifting and current boosting for microcontroller GPIO pins driving higher-load peripherals. IC Role / Device Role / Timing Role: Low-side switch translating 3.3 V or 5 V logic outputs to 12 V/500 mA loads. Use Value: 500 mA IC rating and TO-92 mechanical robustness support repeated switching cycles without degradation in embedded control interfaces. |
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 | Lower VCEO (45 V), same hFE range (200–450), TO-92 package | Not suitable for 48 V rail systems; better for low-voltage battery-powered designs | Select BC547B only when supply voltage remains ≤36 V and higher hFE improves bias stability at microampere base currents |
| MPSA13 | Higher hFE (50–250), same VCEO (60 V), same TO-92 package | Preferred for Darlington-like gain requirements but exhibits slower fT (~50 MHz) and higher VCE(sat) | Choose MPSA13 when circuit demands >200 hFE at low IC, accepting trade-offs in speed and saturation loss |
Compared with BC547B and MPSA13, the MPSA05_D75Z delivers balanced performance: superior voltage margin over BC547B and faster switching with lower saturation loss than MPSA13 - making it optimal for mid-range analog and switching tasks requiring reliability across 5–48 V domains.

FAQ
What is the maximum collector current rating for MPSA05_D75Z?
The MPSA05_D75Z has a maximum continuous collector current (IC) rating of 500 mA at TA = 25°C. Derating is required above 25°C at 5.0 mW/°C, meaning usable current decreases linearly with ambient temperature rise. This rating allows the MPSA05_D75Z to reliably drive moderate loads such as relays, small solenoids, and LED arrays without thermal runaway under proper PCB layout and ventilation.
Does MPSA05_D75Z support switching applications?
Yes, the MPSA05_D75Z supports switching applications due to its low VCE(sat) of ≤0.25 V at IC/IB = 100 mA/10 mA and fast fT of 100 MHz. It is commonly used in saturated-switch configurations for PWM-driven loads like fans, LEDs, and small motors. Its TO-92 package provides adequate thermal mass for intermittent duty cycles, though continuous 500 mA switching requires careful thermal design.
What is the pin configuration of MPSA05_D75Z in TO-92 package?
The MPSA05_D75Z uses standard TO-92 pinout: Pin 1 is Emitter, Pin 2 is Base, and Pin 3 is Collector - verified per Fairchild's official datasheet Rev. 1.3 and ON Semiconductor's updated documentation. This configuration applies to both straight-lead and bent-lead variants and is consistent across all MPSA05-marked devices, including MPSA05_D75Z.
How does MPSA05_D75Z compare to MMBTA05?
The MPSA05_D75Z is the TO-92 packaged version of the same NPN amplifier die used in the SOT-23 MMBTA05. Key differences include higher power dissipation (625 mW vs. 350 mW), lower thermal resistance (RθJA = 200°C/W vs. 357°C/W), and through-hole mounting. The MPSA05_D75Z offers better thermal handling and ease of prototyping, while MMBTA05 suits space-constrained PCBs.
Is MPSA05_D75Z suitable for automotive applications?
No, the MPSA05_D75Z is not qualified for automotive applications. Per Fairchild's Authorized Use policy and ON Semiconductor's documentation, it is designated as a commercial-grade device intended for industrial and consumer use only. It lacks AEC-Q101 qualification, extended temperature validation beyond −55°C to +150°C, and automotive-specific reliability testing - making it unsuitable for vehicle subsystems.
