Product details

Overview

MPS750G from onsemi is a PNP general-purpose amplifier transistor in TO-92 package, rated for V_CEO = 40 V, I_C = 2.0 A continuous, and P_D = 625 mW at T_A = 25°C. It delivers h_FE ≥ 75 at I_C = 50 mA and V_CE = 2.0 V, with V_CE(sat) ≤ 0.5 V at I_C = 2.0 A / I_B = 200 mA, and is used in low-voltage linear amplification and switching circuits in industrial control modules.

For engineers reviewing the MPS750G datasheet, pinout, applications, or equivalent options, key selection criteria include its PNP polarity, TO-92 mechanical compatibility, DC current gain stability across −55°C to +150°C, saturation voltage under high-current drive, and safe operating area (SOA) limits defined up to 2.0 A and −40 V.

Technical Context

The MPS750G operates as a medium-power PNP bipolar junction transistor optimized for linear amplification and saturated-switching applications. Its design supports DC current gain (h_FE) ≥ 75 at low-to-moderate collector currents (50–500 mA), with guaranteed V_CE(sat) ≤ 0.5 V at I_C = 2.0 A and I_B = 200 mA, and V_BE(on) ≤ 1.0 V at I_C = 1.0 A.

Thermal performance is characterized by R_θJA = 200°C/W (junction-to-ambient) and R_θJC = 83.3°C/W (junction-to-case), enabling operation within −55°C to +150°C junction temperature range. The device meets Pb-free requirements and is qualified per onsemi's standard reliability testing for discrete transistors.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	40 V - Maximum collector-emitter voltage before breakdown at I_C = 10 mA, defining safe DC blocking capability in PNP switch configurations.
I_C (cont.)	2.0 A - Continuous collector current rating, setting upper limit for sustained load-driving capability in relay drivers or power stage bias networks.
P_D @ T_A	625 mW - Maximum power dissipation at ambient 25°C, requiring heatsinking or derating above 25°C at 5.0 mW/°C.
h_FE	≥ 75 - Minimum DC current gain at I_C = 50 mA and V_CE = 2.0 V, ensuring predictable base drive requirements in amplifier stages.
V_CE(sat)	≤ 0.5 V - Collector-emitter saturation voltage at I_C = 2.0 A / I_B = 200 mA, directly determining conduction loss and thermal rise in switching applications.
f_T	75 MHz - Current-gain bandwidth product at I_C = 50 mA, V_CE = 5.0 V, indicating usable small-signal amplification up to audio and low-RF frequencies.

Pinout & Package

Package: TO-92 (Case 29-11), straight-lead or bent-lead configuration, Pb-free, with Emitter (Pin 1), Base (Pin 2), Collector (Pin 3) pinout confirmed per onsemi marking diagram and package outline.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	PNP emitter terminal	Reference node for current flow; connects to higher potential rail in common-emitter switching; requires proper biasing for linear operation.
2 (Base)	Control input terminal	Accepts forward-biased current to turn on transistor; base resistor sizing must ensure I_B ≥ I_C/h_FE(min) for full saturation.
3 (Collector)	Output current terminal	Sinks load current when active; connected to load and supply return path; voltage swing limited by V_CEO and SOA boundaries.

Key Features

Feature	Design Value
Pb-free TO-92 packaging	Complies with RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for surface-mount assembly.
Guaranteed h_FE ≥ 75	Ensures consistent current amplification across production lots, reducing need for binning or feedback compensation in fixed-gain stages.
V_CE(sat) ≤ 0.5 V @ 2 A	Minimizes power loss and self-heating during high-current switching, supporting reliable operation in 24 V industrial control outputs.
−55°C to +150°C T_J	Enables deployment in automotive engine compartments, industrial motor drives, and outdoor power supplies without thermal derating penalties.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MMBT750LT1G	SOT-23 package (3-pin), lower I_C = 1.0 A, P_D = 350 mW, same V_CEO = 40 V and h_FE ≥ 75.	Surface-mount only; unsuitable for through-hole PCBs or >1.0 A loads; preferred for space-constrained consumer electronics.	Select when board real estate is critical and peak current stays below 1.0 A; verify thermal pad layout for SOT-23 power handling.
BC807-40	SOT-23 package, V_CEO = 45 V, I_C = 500 mA, h_FE = 250–630 (wide gain spread), P_D = 300 mW.	Higher gain variability requires design margining; insufficient for >500 mA continuous loads; best for low-power signal inversion.	Choose for low-current logic-level translation where gain tolerance is acceptable; avoid for power switching or precision current sourcing.

Compared with MMBT750LT1G and BC807-40, the MPS750G provides higher current capacity (2.0 A vs. ≤1.0 A), through-hole TO-92 compatibility, and tighter h_FE consistency-making it optimal for industrial-grade relay drivers and linear regulators where mechanical robustness and thermal headroom are essential.

FAQ

What is the maximum collector-emitter voltage rating for the MPS750G?

The MPS750G has a maximum collector-emitter voltage (V_CEO) rating of 40 Vdc, specified at I_C = 10 mA and I_B = 0. This defines the absolute upper limit for DC voltage applied between collector and emitter while maintaining safe non-breakdown operation. Exceeding this value risks irreversible avalanche failure. Designers should apply appropriate derating-typically 20%-in safety-critical applications.

Does the MPS750G support operation at elevated temperatures?

Yes, the MPS750G is rated for junction temperatures from −55°C to +150°C. Its thermal resistance values-R_θJA = 200°C/W and R_θJC = 83.3°C/W-enable reliable operation in environments such as industrial motor control cabinets or automotive under-hood locations, provided PCB copper area or chassis mounting satisfies thermal dissipation requirements per the device's power dissipation curve.

What is the typical DC current gain (h_FE) of the MPS750G at 50 mA collector current?

The MPS750G guarantees a minimum DC current gain (h_FE) of 75 at I_C = 50 mA and V_CE = 2.0 V, per onsemi's Electrical Characteristics table. Typical h_FE may exceed 100 under these conditions, but designs must use the 75 minimum for worst-case base drive calculations to ensure saturation across process and temperature variation.

Can the MPS750G be used in switching applications?

Yes, the MPS750G is explicitly characterized for saturated switching, with V_CE(sat) ≤ 0.5 V at I_C = 2.0 A and I_B = 200 mA. Its safe operating area (SOA) graph confirms stable operation up to 2.0 A and −40 V, making it suitable for relay drivers, lamp ballasts, and half-bridge high-side switches-provided base drive is sufficient and thermal limits are observed.

Is the MPS750G RoHS-compliant and lead-free?

Yes, the MPS750G is a Pb-free device, as indicated by the "G" suffix and confirmed in the Ordering Information table. It complies with EU RoHS Directive 2011/65/EU and meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for reflow soldering. The TO-92 package uses matte tin plating on leads and conforms to onsemi's Pb-free manufacturing standards.
