Product details
Overview
MPS651RLRMG from onsemi is an NPN bipolar junction transistor (BJT) designed for medium-power linear and switching applications, with VCEO = 60 V, IC = 2.0 A, PD = 1.5 W at TC = 25°C, hFE ≥ 75 at IC = 50 mA, and TO-92 package. It serves as a general-purpose amplifier or switch in power supply control circuits, motor drivers, and relay drivers.
For engineers reviewing the MPS651RLRMG datasheet, pinout, applications, or equivalent options, key selection criteria include its 60 V VCEO, 2.0 A continuous collector current capability, low VCE(sat) of 0.3 V at IC/IB = 10, thermal resistance of 83.3 °C/W (junction-to-case), and Pb-free TO-92 packaging for lead-free assembly compliance.
Technical Context
The MPS651RLRMG operates as a silicon NPN BJT with a maximum collector-emitter breakdown voltage of 60 V and collector-base breakdown voltage of 80 V. Its DC current gain remains ≥75 up to IC = 500 mA and drops to ≥40 at IC = 2.0 A under VCE = 2.0 V bias.
It delivers VCE(sat) ≤ 0.3 V at IC = 1.0 A / IB = 100 mA and ≤ 0.5 V at IC = 2.0 A / IB = 200 mA, with VBE(on) ≤ 1.0 V and VBE(sat) ≤ 1.2 V under same conditions. Its fT is rated at 75 MHz at IC = 50 mA, VCE = 5.0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 60 V - Maximum safe collector-emitter voltage before avalanche breakdown; enables use in 48 V systems and higher-voltage DC-DC stages. |
| IC (cont.) | 2.0 A - Continuous collector current rating; supports medium-power switching loads such as solenoids and small motors. |
| PD @ TC=25°C | 1.5 W - Power dissipation limit at case temperature; requires heatsinking above ~0.8 W in ambient operation. |
| hFE | ≥75 @ IC=50 mA - Sufficient DC gain for direct base drive without additional pre-amplification in many control circuits. |
| VCE(sat) | ≤0.3 V @ IC=1.0 A - Low saturation voltage minimizes conduction loss and self-heating in switching applications. |
| fT | 75 MHz - Enables stable operation in audio-frequency amplifiers and moderate-speed switching (e.g., PWM up to ~1–2 MHz). |
Pinout & Package
Package: TO-92 (Case 29-11), straight-lead, Pb-free, tape-and-ammo packaging. Dimensions conform to JEDEC TO-226 standard: body height ~4.8 mm, lead pitch 2.54 mm, max width ~5.3 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Current exit path for majority carriers | Connected to ground or low-side return; determines common-emitter configuration reference point. |
| 2 (Base) | Control terminal for minority carrier injection | Receives current-limited drive signal; base resistor selection must ensure IB ≥ IC/hFE(min) for saturation. |
| 3 (Collector) | Current entry path and output node | Connected to load and supply rail; handles full switched current and must be routed with adequate copper area for thermal relief. |
Key Features
| Feature | Design Value |
|---|---|
| Pb-free TO-92 package | Complies with RoHS Directive 2011/65/EU and JEDEC J-STD-020 reflow profiles; suitable for lead-free SMT-compatible through-hole assembly. |
| High VCEO (60 V) | Supports operation across industrial 24–48 V DC bus systems without derating; eliminates need for higher-voltage, costlier alternatives in many controls. |
| Low VCE(sat) (0.3 V) | Reduces power loss to ≤300 mW at 1 A load, easing thermal design and improving efficiency in battery-powered or thermally constrained modules. |
| Wide TJ range (−55 to +150°C) | Enables deployment in automotive under-hood, industrial motor control, and outdoor equipment without external thermal protection circuitry. |
Applications
| Power Supply Feedback Control | DC Motor On/Off Driver |
|---|---|
Use Scenario: Regulating output voltage in isolated flyback or forward converters via optocoupler-coupled feedback loop. IC Role / Device Role / Timing Role: NPN switch amplifying error amplifier output to drive optocoupler LED with precise current control. Use Value: Stable 60 V VCEO withstands reflected transients; 75+ hFE ensures reliable LED drive across temperature without gain compensation. |
Use Scenario: Controlling 12–24 V brushed DC motors in HVAC actuators or industrial valves. IC Role / Device Role / Timing Role: Low-side switch turning motor winding on/off in response to MCU GPIO signals. Use Value: 2.0 A IC rating covers stall currents; 0.3 V VCE(sat) limits heat generation during sustained ON periods. |
| Relay Coil Driver | Linear Voltage Regulator Pass Element |
Use Scenario: Driving 5–24 V DC relay coils requiring 20–150 mA holding current in PLC I/O modules. IC Role / Device Role / Timing Role: General-purpose NPN switch interfacing microcontroller outputs to inductive relay loads. Use Value: 80 V VCBO safely clamps coil flyback spikes; TO-92 mechanical robustness supports high-cycle industrial operation. |
Use Scenario: Serving as pass transistor in adjustable linear regulators delivering up to 1.5 A output current. IC Role / Device Role / Timing Role: Series-pass element dissipating excess input-output differential voltage as heat. Use Value: 1.5 W PD at TC = 25°C allows ~1.2 W usable dissipation with modest heatsink; wide TJ range accommodates ambient drift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN medium-power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MPS651G | Bulk-packaged variant; identical electrical specs and TO-92 footprint; no tape-and-ammo convenience. | Suitable for manual prototyping or low-volume hand-soldered builds where reel/ammo handling is unnecessary. | Select MPS651G when automated placement is not required and lower per-unit cost justifies bulk handling. |
| STMicroelectronics BU508A | Higher VCEO (1500 V), higher IC (10 A), larger TO-220 package; significantly higher thermal mass and dissipation (125 W). | Targeted at horizontal deflection and high-energy switching; overqualified for low-power control, adds PCB area and cost. | Choose BU508A only if system-level surge immunity >600 V or continuous current >2 A is required-otherwise MPS651RLRMG offers optimal size/performance balance. |
Compared with MPS651G, MPS651RLRMG provides identical performance in a tape-and-ammo format ideal for automated assembly; versus BU508A, it trades extreme ruggedness for compact TO-92 integration, lower cost, and sufficient margin for 48 V-class industrial control.

FAQ
What is the maximum operating junction temperature for MPS651RLRMG?
The MPS651RLRMG has a specified operating and storage junction temperature range of −55°C to +150°C. This allows deployment in demanding environments such as automotive engine compartments or industrial motor drives. Thermal design must ensure that actual TJ stays within this limit under worst-case power dissipation and ambient conditions-using the 83.3 °C/W junction-to-case thermal resistance to calculate required heatsinking.
Is MPS651RLRMG pin-compatible with MPS650RLRMG?
No, MPS651RLRMG is not pin-compatible with MPS650RLRMG in terms of electrical ratings-though both share the same TO-92 package and pinout (Emitter-Base-Collector). The MPS651RLRMG has higher voltage ratings (VCEO = 60 V vs. 40 V, VCBO = 80 V vs. 60 V) and identical pin assignment. Substitution requires verification that the higher voltage capability is needed and that system-level stress margins remain valid.
Does MPS651RLRMG support surface-mount assembly?
MPS651RLRMG is supplied in TO-92 straight-lead tape-and-ammo packaging, intended for through-hole mounting. While it can be adapted to surface-mount via specialized carriers or wave-solder tooling, it is not designed for standard reflow soldering due to lead geometry and thermal mass mismatch. For true SMT compatibility, consider onsemi's SOT-23 or DPAK alternatives like NSS12201MR6T1G.
What is the typical DC current gain (hFE) of MPS651RLRMG at 1 A collector current?
The MPS651RLRMG guarantees hFE ≥ 40 at IC = 1.0 A, VCE = 2.0 V, and TA = 25°C. This value reflects minimum gain under high-current saturation conditions-designers should size base drive accordingly (e.g., IB ≥ 25 mA for 1 A collector current) and verify gain stability across temperature using Figure 1 from the datasheet.
Can MPS651RLRMG be used in linear amplifier configurations?
Yes, MPS651RLRMG supports linear amplifier use, with fT = 75 MHz and hFE ≥ 75 at IC = 50 mA. However, its SOA (Safe Operating Area) limits linear operation to low-voltage, low-current regions-Figure 7 shows second breakdown constraints below 10 V and 1 A. For sustained linear gain, ensure VCE × IC remains within thermal and wire-bond limits, and implement appropriate bias stabilization.
