Product details
Overview
MPS751RLRAG from onsemi is a PNP general-purpose amplifier transistor in TO-92 package, rated for 60 VCEO, 2.0 A continuous collector current, and 1.5 W power dissipation at TC = 25°C. It delivers hFE ≥ 75 at IC = 50 mA and VCE = 2.0 V, with VCE(sat) ≤ 0.3 V at IC = 1.0 A / IB = 100 mA - suitable for linear amplification and switching in low-voltage industrial control circuits.
For engineers reviewing the MPS751RLRAG datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed DC current gain across temperature, low saturation voltage under high-current drive, thermal resistance (83.3°C/W junction-to-case), and Pb-free TO-92 packaging compliance for automated assembly.
Technical Context
The MPS751RLRAG is a silicon PNP bipolar junction transistor optimized for medium-power linear and switching applications. Its design supports stable hFE ≥ 75 up to IC = 500 mA and maintains VCE(sat) ≤ 0.5 V at IC = 2.0 A / IB = 200 mA, enabling efficient operation in Class-A amplifiers and relay drivers.
It features a maximum V(BR)CBO of 80 V and V(BR)CEO of 60 V, with EBO breakdown at 5.0 V. Thermal performance is defined by RθJC = 83.3°C/W and RθJA = 200°C/W, supporting operation from −55°C to +150°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)CEO | 60 V - Ensures safe operation in 48 V rail systems with margin against transients |
| IC Continuous | 2.0 A - Supports load switching up to ~24 W at 12 V with adequate heatsinking |
| hFE @ 50 mA | ≥ 75 - Provides predictable base drive requirements for biasing in amplifier stages |
| VCE(sat) @ 1 A | ≤ 0.3 V - Minimizes conduction loss and self-heating in saturated switch mode |
| fT | 75 MHz - Enables use in audio-frequency amplification and low-speed digital switching |
| RθJC | 83.3°C/W - Allows direct mounting to small metal heatsinks for thermal management |
| TJ Range | −55°C to +150°C - Qualified for industrial and automotive under-hood ambient conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP medium-power amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPS751G | Bulk-pack variant; identical electrical specs and TO-92 package; no tape-and-reel handling features | Suitable for manual prototyping or low-volume hand-soldered assemblies | Select MPS751G for engineering samples or small-batch builds where reel automation is unnecessary |
| BC807-40 | Smaller SOT-23 package; lower IC (500 mA); hFE 250–630 (wider spread); V(BR)CEO = 45 V | Limited to low-power signal switching; not suitable for 2 A loads or 48 V transient environments | Choose BC807-40 only for space-constrained PCBs with sub-500 mA requirements and no high-voltage stress |
Compared with MPS751G and BC807-40, the MPS751RLRAG offers tape-and-reel compatibility for automated placement, guaranteed 2 A capability, and 60 V breakdown margin - making it optimal for volume-manufactured industrial controls requiring robustness and process efficiency.

FAQ
What is the maximum continuous collector current rating for the MPS751RLRAG?
The MPS751RLRAG is rated for 2.0 A continuous collector current at TC = 25°C. Derating applies above 25°C at 12 mW/°C. This rating assumes proper heatsinking; operation at full current without thermal management will exceed the 150°C maximum junction temperature limit.
Does the MPS751RLRAG have Pb-free construction?
Yes, the MPS751RLRAG is a Pb-free device compliant with RoHS Directive 2011/65/EU. The "RLRA" suffix denotes tape-and-reel packaging, and the "G" in the full part number (MPS751RLRAG) confirms Pb-free termination per onsemi's standard marking convention.
What is the DC current gain (hFE) of the MPS751RLRAG at 1.0 A collector current?
The MPS751RLRAG guarantees hFE ≥ 75 at IC = 50 mA and VCE = 2.0 V. At IC = 1.0 A, hFE drops to ≥ 40 per the datasheet's "ON CHARACTERISTICS" table - a critical value for designing base drive networks in high-current switching applications.
Can the MPS751RLRAG be used as a direct replacement for the MPS750 series?
No - the MPS751RLRAG has higher voltage ratings (V(BR)CEO = 60 V vs. 40 V for MPS750) and identical pinout but different Safe Operating Area limits. Substituting into an MPS750-designed circuit may cause overstress under transient conditions unless layout and protection are revalidated.
What is the thermal resistance junction-to-case (RθJC) for the MPS751RLRAG?
The MPS751RLRAG has a specified thermal resistance of 83.3°C/W from junction to case. This value enables accurate calculation of junction temperature rise when mounted to a heatsink, assuming low thermal interface resistance between the TO-92 tab and heatsink surface.
