Product details
Overview
MPS751RLRP from onsemi is a PNP bipolar junction transistor (BJT) in TO-92 package, rated for 60 V collector-emitter breakdown voltage, 2.0 A continuous collector current, and 1.5 W power dissipation at case temperature. 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 medium-power linear amplification and switching in industrial control interfaces.
For engineers reviewing the MPS751RLRP datasheet, pinout, applications, or equivalent options, key selection criteria include verified PNP polarity, TO-92 mechanical compatibility, DC current gain stability across −55°C to +150°C, and safe operating area (SOA) compliance up to 2.0 A/−60 V under pulsed conditions.
Technical Context
This PNP transistor operates with emitter-base forward bias and collector-base reverse bias in active or saturation mode. Its thermal resistance junction-to-case is 83.3°C/W, enabling 1.5 W dissipation at TC = 25°C with linear derating of 12 mW/°C above that point.
Electrical behavior is characterized by V(BR)CEO = 60 V (IC = 10 mA), V(BR)CBO = 80 V (IC = 100 μA), and VBE(on) ≤ 1.0 V at IC = 1.0 A - confirming robust turn-on capability and high-voltage blocking integrity for discrete amplifier stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)CEO | 60 V - Maximum collector-emitter voltage before breakdown at IC = 10 mA; defines upper rail limit in PNP switch or amplifier designs. |
| IC Continuous | 2.0 A - Sustained collector current capacity; supports medium-power load driving without forced cooling. |
| PD @ TC = 25°C | 1.5 W - Power dissipation limit at case temperature; requires heatsinking beyond ambient-limited operation. |
| hFE Min | 75 - Minimum DC current gain at IC = 50 mA and VCE = 2.0 V; ensures predictable base drive sizing. |
| VCE(sat) | 0.3 V - Collector-emitter saturation voltage at IC = 1.0 A / IB = 100 mA; enables low-loss switching in relay drivers. |
| fT | 75 MHz - Current-gain bandwidth product at IC = 50 mA; supports audio-frequency amplification and fast-switching applications. |
Pinout & Package
Package: TO-92 (Case 29-11), straight-lead, Pb-free, through-hole mounting. Dimensions per ANSI Y14.5M: body height 4.45–5.20 mm, lead pitch 2.54 mm, emitter-base-collector pinout confirmed.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current source terminal in PNP configuration | Connected to higher potential rail; base current flows out of this terminal during conduction. |
| 2 (Base) | Control input for minority-carrier injection | Receives negative-going drive signal relative to emitter; determines conduction state and gain. |
| 3 (Collector) | Current sink terminal | Connected to load and lower-potential node; carries full emitter current minus base current. |
Key Features
| Feature | Design Value |
|---|---|
| Pb-free TO-92 packaging | Complies with RoHS Directive 2011/65/EU; eliminates lead contamination risk in assembly and end-of-life handling. |
| Junction temperature range | −55°C to +150°C operation; supports deployment in automotive engine compartments and industrial motor controls. |
| Safe Operating Area (SOA) | Validated up to 2.0 A / −60 V with 100 μs pulse width; enables reliable transient overload tolerance in protection circuits. |
| Low VCE(sat) | ≤ 0.3 V at IC = 1.0 A / IB = 100 mA; reduces conduction losses and thermal stress in high-duty-cycle switching. |
Applications
| Industrial Relay Driver | Linear Voltage Regulator Pass Element |
|---|---|
|
Use Scenario: Driving 24 VDC industrial relays with coil currents up to 1.8 A in programmable logic controller (PLC) output modules. IC Role / Device Role / Timing Role: PNP switch controlling relay coil current path from +24 V supply to ground via collector-emitter path.

IC Role / Device Role / Timing Role: PNP pass element regulating output voltage by modulating emitter-collector current under feedback control. Use Value: hFE ≥ 75 ensures stable loop gain; 1.5 W PD @ TC = 25°C supports thermal management with minimal heatsink. |
| DC Motor Direction Control | High-Side Load Switch |
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP medium-power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPS751G | Bulk-packaged variant; identical electrical specs and TO-92 package; no tape-and-reel convenience. | Suitable for prototyping and low-volume manual assembly where reel feeding is unnecessary. | Select MPS751G when automated pick-and-place is not required and cost-per-unit is prioritized over packaging logistics. |
| BC639 | Lower V(BR)CEO = 45 V; same TO-92 package; hFE = 40–250 (wider spread); fT = 100 MHz. | Acceptable in 12–24 V systems but lacks 60 V margin for industrial transients or 48 V architectures. | Choose BC639 only if design operates strictly below 40 V and requires higher fT, accepting reduced voltage headroom and gain consistency. |
Compared with MPS751RLRP, MPS751G offers identical performance in bulk form but lacks tape-and-reel handling; BC639 trades 15 V breakdown margin and statistical hFE variation for slightly higher bandwidth - making MPS751RLRP preferable for robust 48 V-compatible industrial switching.

FAQ
What is the maximum collector-emitter voltage rating for MPS751RLRP?
The MPS751RLRP has a guaranteed minimum collector-emitter breakdown voltage V(BR)CEO of 60 V at IC = 10 mA and IB = 0. This rating allows safe operation in 48 V industrial systems with margin for transient spikes, and is confirmed in the official onsemi datasheet revision 4 for MPS650/D.
Does MPS751RLRP support operation at elevated temperatures?
Yes, the MPS751RLRP is specified for junction and storage temperature ranging from −55°C to +150°C. Its thermal resistance junction-to-case is 83.3°C/W, enabling reliable use in engine control units and industrial enclosures where ambient temperatures exceed 85°C - provided case temperature remains within limits.
What package type and pin configuration does MPS751RLRP use?
MPS751RLRP uses the TO-92 package (Case 29-11) with straight leads and Pb-free finish. Pin 1 is Emitter, Pin 2 is Base, and Pin 3 is Collector - consistent across all MPS75x variants and verified in the onsemi package dimension drawing and marking diagram.
How does the DC current gain (hFE) of MPS751RLRP vary with collector current?
Per the onsemi datasheet Figure 2, MPS751RLRP maintains hFE ≥ 75 at IC = 50 mA and VCE = −2.0 V, drops to ≥ 75 at IC = 500 mA, and remains ≥ 40 at IC = 2.0 A. This flat gain profile supports stable biasing across wide dynamic load ranges in amplifier and switch applications.
Is MPS751RLRP suitable for high-frequency switching applications?
MPS751RLRP has an fT of 75 MHz at IC = 50 mA, VCE = 5.0 V, and f = 100 MHz. While sufficient for audio-range amplifiers and PWM switching up to ~500 kHz, it is not optimized for RF or MHz-class digital switching - where RF transistors or MOSFETs would provide superior speed and efficiency.
