Product details
Overview
MPSA06RA from ON Semiconductor is an NPN general-purpose amplifier transistor designed for linear amplification and switching in low-to-medium power analog circuits, with VCEO = 80 V, IC = 500 mA, hFE ≥ 100 at 10 mA/1 V, fT = 100 MHz, and TO-92 package. It serves in audio preamplifier stages, signal buffering, and discrete logic-level translation where robust DC gain and moderate frequency response are required.
For engineers reviewing the MPSA06RA datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, validated TO-92 terminal mapping, real-world use cases in analog signal chains, and two confirmed alternative transistors with documented performance trade-offs - all aligned to Fairchild/ON Semiconductor Rev. 1.1.0 specification.
Technical Context
The MPSA06RA operates as a silicon NPN bipolar junction transistor optimized for general-purpose linear amplification up to 100 MHz, with guaranteed hFE ≥ 100 at both IC = 10 mA and IC = 100 mA under VCE = 1.0 V. Its VCEO and VCBO ratings of 80 V support operation in 48 V and lower industrial supply rails.
Thermal design is constrained by RθJA = 200 °C/W on FR-4 PCB (1.6″ × 1.6″), limiting continuous dissipation to 625 mW at 25 °C ambient and derating at 5.0 mW/°C above that. The device exhibits VCE(sat) ≤ 0.25 V at IC = 100 mA / IB = 10 mA, enabling efficient saturated switching in discrete gate drivers and relay interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Maximum collector-emitter voltage before breakdown; supports 48 V system rails with 67% safety margin. |
| IC (max) | 500 mA - Continuous collector current rating; enables drive capability for small relays, LEDs, and low-power solenoids. |
| hFE | ≥100 at 10 mA/1 V - Minimum DC current gain ensures predictable biasing in Class-A amplifiers and emitter-follower buffers. |
| fT | 100 MHz - Gain-bandwidth product confirms usability in RF preamp stages up to ~10–20 MHz with stable gain. |
| VCE(sat) | ≤0.25 V at IC=100 mA/IB=10 mA - Low saturation voltage reduces conduction loss in switching applications. |
| PD | 625 mW at 25°C - Total power dissipation limit defines thermal envelope for TO-92 mounting on standard PCBs. |
Pinout & Package
MPSA06RA is housed in a through-hole TO-92 3-lead molded package with straight leads and standard JEDEC outline. Package dimensions conform to Figure 11 in Rev. 1.1.0, with lead pitch of 1.27 mm and body height ≤ 4.57 mm.
| 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 configurations. |
| B (Base) | Control input | Receives current-limited drive to set operating point; requires series resistor to limit IB per hFE target. |
| C (Collector) | Current source terminal | Delivers amplified output current; connects to load and positive supply in active-load or resistive-load topologies. |
Key Features
| Feature | Design Value |
|---|---|
| General-purpose amplifier optimization | Validated hFE ≥ 100 across 10–100 mA range ensures stable biasing without gain compression in mid-current analog stages. |
| High VCEO/VCBO rating | 80 V breakdown supports use in 24–48 V industrial control inputs without external clamping diodes. |
| Low VCE(sat) | 0.25 V max at 100 mA enables <100 mW conduction loss in switching mode - critical for thermally constrained TO-92 layouts. |
| 100 MHz fT | Confirms usable bandwidth for audio band (20 Hz–20 kHz) amplification with >60 dB gain margin and RF front-end preamp feasibility. |
Applications
| Audio Preamp Stage | Discrete Logic-Level Translator |
|---|---|

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; RθJA = 357 °C/W; PD = 350 mW; same VCEO, hFE, and fT. | Requires PCB rework for space-constrained designs; unsuitable for prototyping with breadboards or through-hole test fixtures. | Select when board area is limited and thermal management uses copper pour or forced air. |
| BC548B | VCEO = 30 V; hFE = 200–450 (min 110); fT = 300 MHz; TO-92 package; lower voltage rating but higher gain and speed. | Not suitable for 48 V systems; better for low-voltage audio or RF stages where gain stability at low IC is prioritized. | Choose only if supply voltage remains ≤ 24 V and high-frequency response beyond 50 MHz is required. |
Compared with MMBTA06 and BC548B, the MPSA06RA uniquely balances 80 V breakdown, 500 mA current handling, and TO-92 through-hole compatibility - making it the preferred choice for industrial interface circuits requiring field-serviceable assembly and 48 V system resilience.

FAQ
What is the maximum collector-emitter voltage rating for MPSA06RA?
The MPSA06RA has a VCEO rating of 80 V, verified per Absolute Maximum Ratings table in Rev. 1.1.0. This rating applies at TA = 25°C with no derating, and defines the upper limit for collector-to-emitter voltage before avalanche breakdown occurs. Exceeding this value risks permanent device failure.
Does MPSA06RA support switching applications, and what is its saturation voltage?
Yes, MPSA06RA is qualified for switching use with VCE(sat) ≤ 0.25 V at IC = 100 mA and IB = 10 mA. This low saturation voltage ensures minimal conduction loss and self-heating during ON-state operation, making MPSA06RA suitable for relay drivers and digital output buffers in industrial controls.
What is the DC current gain (hFE) of MPSA06RA, and under what conditions is it specified?
The MPSA06RA guarantees hFE ≥ 100 at two operating points: IC = 10 mA, VCE = 1.0 V and IC = 100 mA, VCE = 1.0 V. These values are measured per Electrical Characteristics table in Rev. 1.1.0 and reflect minimum gain across the intended linear amplification range.
Is MPSA06RA available in surface-mount packages, and how does it compare to MMBTA06?
No - MPSA06RA is exclusively offered in TO-92 through-hole packaging. The MMBTA06 is its SOT-23 surface-mount counterpart with identical electrical specs (VCEO, hFE, fT) but lower power dissipation (350 mW vs. 625 mW) and higher thermal resistance (357 °C/W vs. 200 °C/W).
What is the thermal resistance (RθJA) of MPSA06RA, and how does it affect PCB layout?
MPSA06RA has RθJA = 200 °C/W when mounted on a 1.6″ × 1.6″ FR-4 PCB per Thermal Characteristics table. This means a 625 mW dissipation raises junction temperature by 125°C above ambient - requiring adequate copper area or airflow. Layout must avoid enclosing the TO-92 body and ensure ≥ 1 cm² of 2-oz copper connected to the collector lead.
