Product details

Overview

MPS750RLRA from onsemi is a PNP general-purpose amplifier transistor in TO-92 package, rated for V_CE = 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, commonly used in low-voltage linear amplification and switching circuits.

For engineers reviewing the MPS750RLRA 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 Pb-free tape-and-reel packaging for automated assembly.

Technical Context

This device operates as a silicon planar epitaxial PNP bipolar junction transistor optimized for medium-power linear amplification and saturated switching. Its safe operating area (SOA) is defined up to 2.0 A and −40 V with thermal derating of 5.0 mW/°C above 25°C ambient, and second breakdown-limited performance confirmed per Figure 8 of the datasheet.

Electrical behavior is characterized at T_C = 25°C and T_A = 25°C, with validated parameters including V_(BR)CEO = 40 V (I_C = 10 mA), V_(BR)CBO = 60 V (I_C = 100 μA), and f_T = 75 MHz (I_C = 50 mA, V_CE = 5.0 V). Base-emitter on voltage is specified as V_BE(on) ≤ 1.0 V at I_C = 1.0 A.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE max	40 Vdc - Maximum collector-emitter voltage before breakdown; sets upper rail limit in PNP switch or amplifier stages.
I_C continuous	2.0 Adc - Continuous collector current rating; supports medium-power load driving without forced cooling.
h_FE min	75 at I_C = 50 mA - Minimum DC current gain ensures predictable base drive requirements in linear operation.
V_CE(sat)	≤ 0.5 V at I_C = 2.0 A / I_B = 200 mA - Low saturation voltage minimizes power loss and heating in switching applications.
P_D @ T_A	625 mW at 25°C - Power dissipation limit at ambient; requires thermal derating of 5.0 mW/°C above 25°C.
f_T	75 MHz - Transition frequency defines usable bandwidth for small-signal amplification up to ~10–20 MHz.

Pinout & Package

Package: TO-92 (Case 29-11), straight-lead or bent-lead configuration, Pb-free, epoxy-molded plastic housing with JEDEC-standard dimensions (A = 4.45–5.20 mm, B = 4.32–5.33 mm, C = 3.18–4.19 mm).

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current source terminal for PNP device	Connected to higher potential rail in common-emitter configurations; determines current flow direction and biasing topology.
2 (Base)	Control input for minority-carrier injection	Receives forward-biased current to modulate collector current; requires external resistor network for stable DC biasing.
3 (Collector)	Current sink terminal	Typically tied to load and ground reference; voltage swing at this node defines output signal polarity and swing range.

Key Features

Feature	Design Value
Pb-free TO-92 packaging	Complies with RoHS Directive 2011/65/EU and JEDEC J-STD-020 reflow profiles for lead-free assembly.
Wide operating temperature	−55°C to +150°C junction range enables use in automotive engine compartments and industrial control enclosures.
High f_T bandwidth	75 MHz transition frequency supports audio-frequency amplification and fast-switching digital interface buffering.
Low V_CE(sat)	0.5 V maximum at full 2.0 A load ensures <1 W conduction loss in saturated switch mode at 2 A.
Validated SOA curve	Second-breakdown-limited safe operating area documented in Figure 8 supports reliable pulsed-current design up to 2.0 A.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP medium-power amplifier transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MPS750G	Same die, TO-92 bulk-packaged (5000 units); no tape-and-reel carrier or orientation control.	Suitable for manual prototyping or low-volume hand-soldered builds; not optimized for SMT pick-and-place.	Select MPS750G for bench validation; MPS750RLRA for production automation requiring consistent lead orientation and reel handling.
BC807-40	Smaller SOT-23 package (I_C = 500 mA, V_CE = 45 V, h_FE = 250–630); lower power, higher gain, surface-mount only.	Limited to sub-amp loads; unsuitable for 2 A switching or linear regulation; requires PCB redesign for footprint and thermal relief.	Choose BC807-40 only when board space is constrained and current demand is ≤ 500 mA; not a drop-in replacement for MPS750RLRA.

Compared with MPS750G, MPS750RLRA offers verified tape-and-reel compatibility for automated assembly, while BC807-40 trades current capacity and through-hole serviceability for miniaturization and higher h_FE, necessitating layout changes and thermal reassessment.

FAQ

What is the maximum collector current rating for MPS750RLRA?

The MPS750RLRA is rated for 2.0 A continuous collector current (I_C) at T_A = 25°C. This rating assumes adequate PCB copper area for heat dissipation; derating to 1.5 A is recommended at 70°C ambient. The device also supports short-duration pulsed currents up to 2.0 A within its SOA limits, as shown in Figure 8 of the official datasheet.

Is MPS750RLRA compatible with lead-free reflow soldering processes?

Yes, MPS750RLRA is a Pb-free device compliant with JEDEC J-STD-020 moisture sensitivity level (MSL) 1 and qualified for standard lead-free reflow profiles peaking at 260°C. Its epoxy molding compound and lead finish meet RoHS Directive 2011/65/EU requirements, making it suitable for automated SMT assembly without post-process cleaning.

What is the pin configuration of MPS750RLRA in TO-92 package?

MPS750RLRA uses standard TO-92 pinout: Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector (viewed with flat side facing outward and leads pointing down). This matches the marking diagram on page 1 of the MPS650/D datasheet and is consistent across all MPS75x variants in bent-lead or straight-lead tape-and-reel formats.

How does the DC current gain (h_FE) of MPS750RLRA vary with temperature?

MPS750RLRA maintains h_FE ≥ 75 at I_C = 50 mA and V_CE = 2.0 V across its full operating junction temperature range of −55°C to +150°C, as confirmed by Figure 2 in the datasheet. Gain decreases gradually at extremes: ~100 at −55°C, ~75 at 25°C, and ~60 at 125°C, supporting stable biasing in wide-temperature environments.

Can MPS750RLRA be used as a direct replacement for MPS750G?

Yes, MPS750RLRA shares identical electrical specifications, die, and TO-92 package with MPS750G; the only difference is packaging format - MPS750RLRA is supplied in 2000-unit tape-and-reel with controlled lead orientation, whereas MPS750G is bulk-packed. No circuit or layout changes are required when substituting MPS750RLRA for MPS750G in production.
