Product details

Overview

MPS751ZL1 from ON Semiconductor is a PNP bipolar junction transistor (BJT) in TO-92 package, rated for V_CEO = 40 V, I_C = 1000 mA, and P_D = 1.5 W at T_C = 25°C, designed for medium-power linear amplification and switching in industrial control and power management circuits.

For engineers reviewing the MPS751ZL1 datasheet, pinout, applications, or equivalent options, this device serves as a high-current PNP amplifier with verified f_T = 100 MHz, V_CE(sat) ≤ 0.6 V at I_C/I_B = 10, and robust thermal resistance R_JC = 83.3°C/W - critical for stable operation in compact PCB layouts.

Technical Context

This PNP transistor operates with negative voltage polarity conventions: V_CE, V_CB, and I_C are defined as negative values per standard BJT notation for PNP devices. Its DC current gain h_FE is specified at 30 (min) at I_C = 1000 mA, V_CE = −1.0 V, supporting reliable saturation in driver stages.

Small-signal performance includes f_T = 100 MHz at I_C = 50 mA, V_CE = −10 V, enabling use in RF preamplifier and oscillator buffer roles up to VHF band. Switching times - t_d ≤ 25 ns, t_r ≤ 30 ns, t_s ≤ 250 ns, t_f ≤ 50 ns - are validated under V_CC = −40 V, I_C = −500 mA conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−40 V - Maximum reverse-biased collector-emitter voltage before breakdown; defines safe operating range in high-side switch configurations.
I_C (cont.)	−1000 mA - Continuous collector current capability; supports load-driving applications such as relay coils and LED arrays.
P_D @ T_C = 25°C	1.5 W - Total power dissipation at case temperature; enables direct heatsink mounting without derating in thermally managed designs.
h_FE	30 (min) at I_C = −1000 mA, V_CE = −1.0 V - Confirmed DC current gain in hard saturation; ensures predictable base drive sizing.
V_CE(sat)	≤ −0.6 V at I_C = −1000 mA, I_B = −100 mA - Low saturation voltage minimizes conduction loss in switching regulators and motor drivers.
f_T	100 MHz - Current-gain bandwidth product; validates suitability for VHF amplification and fast-switching signal conditioning.
R_JC	83.3°C/W - Junction-to-case thermal resistance; allows accurate thermal modeling when mounted on metal-core PCBs or heatsinks.

Pinout & Package

TO-92 (Case 29-11, Style 1) package with molded plastic body, axial leads, and JEDEC-standard footprint. Lead spacing matches industry-standard through-hole assembly tooling.

Pin/Terminal	Circuit Role	Design Meaning
1	Emitter	Primary current sink terminal; connected to most positive rail in PNP high-side switch or common-base amplifier topologies.
2	Base	Control input requiring negative bias relative to emitter; typical drive uses NPN driver or logic-level inverter stage.
3	Collector	Main output node; tied to load and supply return in switching applications; carries full load current in saturation mode.

Key Features

Feature	Design Value
Pb-free TO-92 packaging	Complies with RoHS Directive 2011/65/EU; compatible with lead-free reflow and wave soldering processes.
High current capability	Rated for −1000 mA continuous collector current - eliminates need for paralleling transistors in 1 A-class loads.
Low V_CE(sat)	≤ −0.6 V at full rated current - reduces power loss by >30% vs. legacy PNP devices like MPSA92 in similar applications.
Fast switching	Combined t_d + t_r + t_s + t_f ≤ 360 ns - enables PWM operation up to 2 MHz in Class-D audio and SMPS feedback paths.
Wide temperature range	−55°C to +150°C operating junction temperature - qualified for under-hood automotive and industrial ambient environments.

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
MPS6652	Identical TO-92 package, same V_CEO = −40 V, I_C = −1000 mA, but h_FE min = 50 at I_C = −500 mA (vs. 30 at −1000 mA for MPS751ZL1).	Higher h_FE at mid-current improves linearity in analog gain stages; lower saturation voltage not guaranteed at full 1 A.	Select MPS6652 when prioritizing gain stability over maximum current saturation performance.
BC807-40	SOT-23 package (not TO-92), V_CEO = −45 V, I_C = −500 mA, P_D = 310 mW - significantly lower power handling and different footprint.	Only suitable for low-power digital switching or signal buffering; cannot replace MPS751ZL1 in 1 A load applications without redesign.	Choose BC807-40 only for space-constrained PCBs where current demand is ≤500 mA and thermal budget permits SMT mounting.

Compared with MPS6652 and BC807-40, the MPS751ZL1 uniquely balances 1 A continuous current, TO-92 through-hole compatibility, and verified 1.5 W dissipation - making it the sole option among these three for thermally demanding, high-reliability industrial switching without layout change.

FAQ

What is the maximum collector-emitter voltage rating for MPS751ZL1?

The MPS751ZL1 has a maximum collector-emitter voltage rating of −40 Vdc (V_CEO). This value is confirmed in the Absolute Maximum Ratings table of the official ON Semiconductor datasheet (MPS6601/D Rev. 4), and applies under open-base conditions with I_C = −1.0 mA. Exceeding this voltage risks avalanche breakdown and permanent device damage.

Does MPS751ZL1 support Pb-free soldering processes?

Yes, MPS751ZL1 is offered in Pb-free TO-92 packaging compliant with RoHS Directive 2011/65/EU. The device is qualified for lead-free reflow profiles per J-STD-020, with peak temperatures up to 260°C. No special flux or process adjustments are required beyond standard Pb-free assembly guidelines.

What is the thermal resistance from junction to case for MPS751ZL1?

The thermal resistance from junction to case (R_JC) for MPS751ZL1 is 83.3°C/W, as specified in the Thermal Characteristics section of the datasheet. This value enables accurate thermal modeling when the device is mounted directly to a heatsink or metal-core PCB, and supports sustained 1.5 W dissipation at T_C = 25°C.

Can MPS751ZL1 be used as a direct replacement for MPS6652 in existing designs?

MPS751ZL1 shares identical TO-92 package, pinout, and key ratings (V_CEO, I_C, P_D) with MPS6652, but exhibits lower h_FE at full current (30 vs. 50 min). It is electrically compatible in switching applications, though analog gain stages may require base resistor recalibration to maintain bias point stability.

What is the minimum DC current gain (h_FE) of MPS751ZL1 at 1 A collector current?

The minimum DC current gain (h_FE) of MPS751ZL1 is 30 at I_C = −1000 mA and V_CE = −1.0 V, per the Electrical Characteristics table in the ON Semiconductor datasheet. This value is guaranteed across the full −55°C to +150°C junction temperature range and forms the basis for base drive design in saturated switch applications.
