Product details

Overview

MPS750 from onsemi is a PNP bipolar junction transistor (BJT) designed for general-purpose amplification and switching in low-to-medium power linear and digital circuits. It features V_CEO = 40 V, I_C = 2.0 A continuous, P_D = 625 mW at T_A = 25°C, h_FE ≥ 75 at I_C = 50 mA, and TO-92 package - commonly used in relay drivers, power supply error amplifiers, and discrete logic level translators.

For engineers reviewing the MPS750 datasheet, pinout, applications, or equivalent options, key selection considerations include its PNP polarity, saturation voltage of 0.5 V at I_C = 2.0 A / I_B = 200 mA, thermal resistance R_JA = 200°C/W, and Pb-free availability in tape-and-ammo packaging (MPS750RLRPG).

Technical Context

The MPS750 operates as a medium-power PNP BJT with fixed current gain characteristics optimized for DC amplification and hard-switching applications. Its safe operating area (SOA) is defined up to 2.0 A and −4.0 V, limited by thermal and second-breakdown boundaries, and it exhibits V_BE(sat) = 1.2 V at I_C/I_B = 10 under forced-beta conditions.

Electrical behavior is specified across −55°C to +150°C junction temperature range, with breakdown ratings of V_(BR)CBO = 80 V and V_(BR)EBO = 5.0 V. It shares layout-compatible TO-92 footprint with NPN counterparts like MPS650 but requires inverted biasing and complementary drive circuitry.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	40 V - Maximum collector-emitter voltage before avalanche breakdown under open-base condition; defines upper rail limit in PNP switch designs.
I_C (cont.)	2.0 A - Continuous collector current rating; sets maximum load-handling capability in linear regulators or driver stages.
P_D @ T_A	625 mW - Power dissipation limit at 25°C ambient; requires heatsinking or derating above 25°C (5.0 mW/°C).
h_FE	≥75 @ I_C = 50 mA - Minimum DC current gain; ensures reliable base drive sizing for low-current amplification stages.
V_CE(sat)	0.5 V @ I_C = 2.0 A, I_B = 200 mA - Saturation voltage defining conduction loss in switching applications.
R_JA	200°C/W - Junction-to-ambient thermal resistance; determines temperature rise per watt in through-hole PCB mounting without heatsink.

Pinout & Package

Package: TO-92 (Case 29-11), molded plastic, 3-lead through-hole package with standard lead spacing and orientation per ON Semiconductor specification.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Emitting terminal for majority carriers (holes)	Connected to highest potential node in PNP configuration; source of current flow into external load.
2 (Base)	Control electrode for carrier injection	Receives reverse-biased current to turn device ON; requires current-limiting resistor in most drive circuits.
3 (Collector)	Current-collecting terminal	Connected to load return path or ground reference; sinks current when device is active.

Key Features

Feature	Design Value
Pb-Free construction	MPS750RLRPG variant complies with RoHS Directive 2011/65/EU; suitable for environmentally regulated industrial assembly.
High f_T	75 MHz - Enables use in audio-frequency amplifiers and fast-switching applications up to ~10 MHz with gain margin.
Wide T_J range	−55°C to +150°C - Supports operation in automotive under-hood, industrial control, and outdoor power electronics environments.
Low V_BE(on)	1.0 V @ I_C = 1.0 A - Reduces base drive power requirement and eases compatibility with 3.3 V or 5 V microcontroller outputs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MPS751	V_CEO = 60 V, V_(BR)CBO = 80 V, same package and pinout	Higher voltage headroom for 24 V industrial systems; identical drive requirements	Select MPS751 when operating above 40 V collector-emitter stress or requiring extended SOA margin.
BC557	I_C = 100 mA max, h_FE = 110–800, TO-92, lower power (500 mW)	Not suitable for >100 mA loads; better for signal-level amplification than power switching	Choose BC557 only for low-current biasing or preamplifier roles where gain linearity matters more than current capacity.

Compared with MPS751, the MPS750 offers lower voltage rating but identical thermal and switching performance at lower cost; versus BC557, it delivers 20× higher current capability but with narrower h_FE tolerance and higher V_CE(sat), making it appropriate for robust power switching rather than precision analog functions.

FAQ

What is the maximum continuous collector current rating for the MPS750?

The MPS750 has a maximum continuous collector current (I_C) rating of 2.0 A at T_A = 25°C. This value decreases with rising ambient temperature due to its 5.0 mW/°C derating factor. At 100°C ambient, usable I_C drops to approximately 1.375 A. The MPS750 must be operated within its Safe Operating Area (SOA) curve - especially critical during transient overload or switching events - to avoid second breakdown.

Is the MPS750RLRPG variant RoHS-compliant?

Yes, the MPS750RLRPG is a Pb-free (RoHS-compliant) version of the MPS750, packaged in tape-and-ammo format with 2000 units per reel. It meets EU Directive 2011/65/EU and carries the "G" suffix per onsemi's ordering nomenclature. All electrical and thermal specifications remain identical to the standard MPS750; only the termination finish and packaging differ.

Can the MPS750 replace an MPS650 in a circuit?

No - the MPS750 cannot directly replace the MPS650 because they are complementary devices: MPS650 is NPN, MPS750 is PNP. Swapping them without inverting biasing, swapping supply connections, and redesigning base drive would cause immediate circuit failure. They share TO-92 footprint and many ratings (e.g., power, f_T), but polarity reversal makes them functionally incompatible without full schematic revision.

What is the typical DC current gain (h_FE) of the MPS750 at 1.0 A collector current?

The MPS750 specifies h_FE ≥ 75 at I_C = 50 mA, but no minimum is guaranteed at 1.0 A. Figure 2 in the datasheet shows typical h_FE ≈ 40–50 at I_C = 1.0 A and T_J = 25°C. Designers should verify gain under actual operating conditions and allow margin - especially at elevated temperatures, where h_FE degrades significantly - when sizing base drive for the MPS750.

Does the MPS750 have a documented Safe Operating Area (SOA) curve?

Yes, Figure 8 of the official onsemi MPS650/D datasheet provides the SOA curve specifically for the MPS750 and MPS751. It plots allowable collector current versus collector-emitter voltage across multiple pulse widths (100 µs to 100 ms), bounded by thermal limit, wire bond limit, and second breakdown limit. This curve is essential for designing reliable switching applications and must be consulted before using the MPS750 in pulsed or inductive load scenarios.
