Product details
Overview
MPSA06RL1G 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, 100 MHz gain-bandwidth product, and TO-92 package. It serves as a signal amplification or switching element in discrete analog stages of power supplies, sensor interfaces, and industrial control logic.
For engineers reviewing the MPSA06RL1G datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, thermal performance data, package dimensions, and validated alternative parts for discrete BJT selection in cost-sensitive, non-automotive industrial designs.
Technical Context
This device operates as a silicon NPN bipolar junction transistor with DC current gain (hFE) ≥100 at both 10 mA and 100 mA collector current, supporting stable amplification across wide ambient temperature ranges (−55°C to +150°C). Its 80 V VCEO and 4.0 V VEBO ratings enable use in medium-voltage bias networks and interface circuits where moderate voltage headroom is required.
The MPSA06RL1G features low saturation voltage (VCE(sat) ≤ 0.25 V at IC = 100 mA, IB = 10 mA) and base-emitter on voltage (VBE(on) ≤ 1.2 V), enabling efficient drive in TTL-compatible switching stages and low-loss pre-driver configurations without external level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Supports operation in 48 V and 60 V system rails with safety margin against transients. |
| IC Continuous | 500 mA - Enables direct drive of small relays, LEDs, or gate resistors in MOSFET half-bridge pre-drivers. |
| hFE | ≥100 at IC = 10 mA and IC = 100 mA - Ensures predictable current amplification across two decades of operating current. |
| fT | 100 MHz - Sufficient for audio-frequency amplification and fast digital switching up to ~10–20 MHz edge rates. |
| PD | 625 mW at TA = 25°C - Allows continuous operation at ~300 mA with 2 V drop under natural convection on standard FR-4 PCB. |
| RθJA | 200 °C/W - Thermal design requires ≥1 cm² copper pour for sustained 300 mA operation above 50°C ambient. |
Pinout & Package
Package: TO-92 (3-lead molded plastic), through-hole mounting, standard straight lead configuration per JEDEC TO-92. Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector (viewed from flat side with leads down, left-to-right: E-B-C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Emitter (Pin 1) | Current sink terminal | Connected to ground or low-side reference; defines common return path for amplified output current. |
| Base (Pin 2) | Control input | Receives current-limited drive (typically 1–10 mA); bias network must ensure VBE ≤ 1.2 V and avoid reverse breakdown beyond −4.0 V. |
| Collector (Pin 3) | Output current source | Delivers amplified load current; must be isolated from high dv/dt nodes to prevent parasitic turn-on via Cob. |
Key Features
| Feature | Design Value |
|---|---|
| High VCEO rating | 80 V enables use in 48 V industrial bus interfaces and offline auxiliary supply feedback loops without derating. |
| Stable hFE over current range | Minimum gain of 100 maintained from 10 mA to 100 mA, simplifying bias design for multi-load switching stages. |
| Low VCE(sat) | ≤0.25 V at 100 mA/10 mA reduces conduction loss by >30% vs. legacy general-purpose BJTs like 2N3904. |
| Wide operating temperature | −55°C to +150°C junction range supports deployment in unheated enclosures and thermally stressed PCB locations. |

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 |
|---|---|---|---|
| 2N3904 | Lower VCEO (40 V), lower IC (200 mA), lower fT (300 MHz but with reduced gain at high current) | Suitable only for ≤24 V systems and sub-100 mA loads; not recommended for 48 V industrial rails. | Select when cost sensitivity outweighs voltage/current headroom requirements and layout space is constrained. |
| BC547B | Same VCEO (45 V), lower IC (100 mA), hFE binned (200–450), no guaranteed minimum at 100 mA | Limited to low-power signal buffering; unsuitable for relay or LED driver loads exceeding 80 mA. | Prefer for low-noise audio preamp stages where gain consistency matters more than power handling. |
Compared with 2N3904 and BC547B, the MPSA06RL1G provides superior voltage margin, higher continuous current capability, and guaranteed gain stability across its full rated current range-making it the preferred choice for industrial-grade discrete amplification and switching where reliability under sustained load is critical.

FAQ
What is the maximum collector current rating for MPSA06RL1G?
The MPSA06RL1G has a continuous collector current rating of 500 mA, verified per Absolute Maximum Ratings in the official datasheet. This rating applies at TA = 25°C with adequate PCB copper area for heat dissipation. At elevated ambient temperatures or with limited thermal relief, derating is required per the 5.0 mW/°C thermal coefficient. The MPSA06RL1G maintains functional integrity up to this limit when operated within its safe operating area (SOA) boundaries.
Is MPSA06RL1G pin-compatible with MPSA05?
No, the MPSA06RL1G is not pin-compatible with MPSA05. While both are TO-92 packaged NPN transistors, the MPSA05 has a lower VCEO rating (60 V vs. 80 V) and different hFE binning. More critically, the MPSA05 and MPSA06 share identical pinout (E-B-C), but substitution requires verification of circuit-level voltage stress and gain requirements. The MPSA06RL1G should not be assumed interchangeable without redesign validation due to its higher voltage capability and distinct SOA profile.
What is the typical DC current gain (hFE) of MPSA06RL1G at 100 mA collector current?
The MPSA06RL1G guarantees a minimum DC current gain (hFE) of 100 at IC = 100 mA and VCE = 1.0 V, as specified in the Electrical Characteristics table. This value is confirmed across production lots and remains stable from −55°C to +125°C. Unlike some general-purpose BJTs with gain degradation above 50 mA, the MPSA06RL1G sustains this minimum hFE up to its full 500 mA rating, making it suitable for consistent current amplification in switching and linear applications.
Does MPSA06RL1G support operation at −40°C ambient temperature?
Yes, the MPSA06RL1G is fully specified for operation from −55°C to +150°C junction temperature, which corresponds to reliable functionality at −40°C ambient in typical PCB-mounted configurations. Electrical characteristics-including VCEO, hFE, and VCE(sat)-are characterized down to −55°C, and thermal resistance data confirms stable performance under cold-start conditions. The MPSA06RL1G is commonly deployed in outdoor industrial controllers and unheated factory-floor equipment where such low-temperature operation is required.
What is the thermal resistance (RθJA) of MPSA06RL1G in TO-92 package?
The MPSA06RL1G in TO-92 package has a junction-to-ambient thermal resistance (RθJA) of 200°C/W when mounted on a standard FR-4 PCB (1.6 in × 1.6 in × 0.06 in). This value assumes no additional heatsinking and reflects natural convection cooling. For sustained operation near its 500 mA or 625 mW limits, designers must allocate ≥1 cm² of 2-oz copper connected to the collector lead. The MPSA06RL1G's RθJA is significantly lower than alternatives like BC547 (320°C/W), enabling higher power density in space-constrained layouts.
