Product details
Overview
MPSA05RLRAG from ON Semiconductor is an NPN general-purpose amplifier transistor designed for low-to-medium power linear and switching applications up to 300 mA collector current, with 60 V collector-emitter breakdown voltage, 100 MHz gain-bandwidth product, and TO-92 package. It serves as a signal amplification or switching element in discrete analog stages, bias networks, and interface circuits within industrial control modules and consumer electronics.
For engineers reviewing the MPSA05RLRAG datasheet, pinout, applications, or equivalent options, key selection criteria include its VCEO = 60 V rating, hFE ≥ 100 at IC = 10 mA, VCE(sat) ≤ 0.25 V at IC/IB = 100 mA/10 mA, thermal resistance RθJA = 200 °C/W, and compatibility with through-hole PCB assembly.
Technical Context
This device operates as a silicon NPN bipolar junction transistor optimized for DC-coupled amplification and saturated switching in non-critical timing or high-reliability analog subsystems. Its design supports continuous collector currents up to 500 mA and junction temperatures from –55 °C to +150 °C, with base-emitter on voltage of 1.2 V at IC = 100 mA.
The MPSA05RLRAG uses Fairchild's Process 12 fabrication technology and exhibits typical fT = 100 MHz at IC = 10 mA and VCE = 2.0 V, enabling use in audio preamplifier stages and low-frequency pulse shaping circuits where bandwidth beyond 10 MHz is not required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 60 V - Maximum safe collector-emitter voltage before avalanche breakdown; defines upper rail limit in amplifier or switch stage. |
| IC (continuous) | 500 mA - Continuous collector current handling capacity; supports medium-power driver and buffer designs. |
| hFE | ≥100 at IC = 10 mA, VCE = 1.0 V - Sufficient DC current gain for single-stage amplification without cascading. |
| VCE(sat) | ≤0.25 V at IC/IB = 100 mA/10 mA - Low saturation voltage enables efficient switching with minimal conduction loss. |
| fT | 100 MHz - Gain-bandwidth product suitable for audio-frequency amplification and sub-10 MHz digital signal conditioning. |
| RθJA | 200 °C/W - Thermal resistance from junction to ambient on standard FR-4 board; determines maximum power dissipation at given ambient temperature. |
Pinout & Package
Package: TO-92, 3-lead molded plastic case with straight leads. Standard through-hole mounting compatible with legacy PCB layouts and manual soldering processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| E (Emitter) | Current sink terminal | Reference node for bias network; connects to ground or negative rail in common-emitter configuration. |
| B (Base) | Control input | Receives drive current to modulate collector current; requires series resistor for current limiting in digital interface applications. |
| C (Collector) | Current source terminal | Delivers amplified output current to load; connects to positive supply via load resistor or directly to next stage input. |
Key Features
| Feature | Design Value |
|---|---|
| General-purpose NPN architecture | Enables drop-in replacement in legacy amplifier, switch, and level-shifting circuits without redesigning bias networks. |
| 150 °C max junction temperature | Supports operation in enclosed industrial enclosures or under moderate airflow without active cooling. |
| Low VBE(on) = 1.2 V | Reduces base drive requirements in microcontroller-driven switching applications, easing GPIO current sourcing constraints. |

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 |
|---|---|---|---|
| MPSA06RLRAG | VCEO = 80 V (vs. 60 V), same TO-92 package and pinout, identical hFE and fT specs. | Preferred where higher voltage margin is needed in 24 V industrial systems or transient-prone environments. | Select MPSA06RLRAG when operating VCE exceeds 60 V or when design margin against voltage spikes is critical. |
| MMBTA05LT1G | SOT-23 surface-mount package (3-pin), lower PD = 350 mW, same electrical specs except RθJA = 357 °C/W. | Used in space-constrained PCBs requiring automated assembly; unsuitable for >200 mA continuous loads without thermal relief. | Choose MMBTA05LT1G only for compact, reflow-soldered designs where thermal management includes copper pour and airflow. |
Compared with MPSA05RLRAG, MPSA06RLRAG offers higher voltage tolerance without layout change, while MMBTA05LT1G trades package size for reduced thermal performance-making the TO-92 MPSA05RLRAG optimal for cost-sensitive, medium-power through-hole applications requiring proven reliability and serviceability.

FAQ
What is the absolute maximum collector-emitter voltage rating for MPSA05RLRAG?
The absolute maximum VCEO for MPSA05RLRAG is 60 V at TA = 25 °C. This rating is based on a maximum junction temperature of 150 °C and must not be exceeded under any operating condition. Derating is required above 25 °C ambient per the device's thermal characteristics, and pulsed operation requires consultation with ON Semiconductor for duty-cycle validation. The MPSA05RLRAG datasheet specifies this value in the Absolute Maximum Ratings table.
Is MPSA05RLRAG pin-compatible with MPSA06RLRAG?
Yes, MPSA05RLRAG is pin-compatible with MPSA06RLRAG - both use the TO-92 package with identical E-B-C pinout (Emitter-Base-Collector, viewed from flat side with leads down). No PCB layout changes are required when substituting between these two parts, though designers must verify that the lower 60 V VCEO rating of MPSA05RLRAG meets system voltage requirements before replacement. The MPSA05RLRAG and MPSA06RLRAG share identical mechanical and thermal footprints.
What is the typical DC current gain (hFE) of MPSA05RLRAG at 100 mA collector current?
The typical hFE of MPSA05RLRAG is ≥100 at IC = 100 mA and VCE = 1.0 V, matching the minimum specification defined in the Electrical Characteristics table. This gain remains stable across the –55 °C to +125 °C operating range, making the MPSA05RLRAG suitable for temperature-varying environments such as factory-floor controllers. Actual hFE varies by unit and should be validated per application per ON Semiconductor's guidance.
Can MPSA05RLRAG be used in switching applications with 10 kHz PWM signals?
Yes, MPSA05RLRAG supports reliable switching at 10 kHz PWM frequencies due to its fT = 100 MHz and fast saturation characteristics (VCE(sat) ≤ 0.25 V at IC/IB = 100 mA/10 mA). Rise and fall times are typically under 100 ns, enabling clean edge fidelity. For sustained 10 kHz operation, ensure junction temperature stays below 150 °C using appropriate heatsinking or layout copper, as confirmed in the MPSA05RLRAG thermal derating curves.
Does MPSA05RLRAG meet RoHS and REACH compliance standards?
Yes, MPSA05RLRAG is RoHS-compliant and REACH-conformant per ON Semiconductor's published environmental compliance documentation. It contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE), and all substances of very high concern (SVHC) are below threshold limits. Full compliance data for MPSA05RLRAG is available in ON Semiconductor's Material Declaration Report (MDR) portal.
