Product details
Overview
MPS650RLRAG from onsemi is an NPN general-purpose amplifier transistor in TO-92 package, rated for 40 VCEO, 2.0 A continuous collector current, and 625 mW power dissipation at TA = 25°C. It delivers hFE ≥ 75 at IC = 50 mA and VCE = 2.0 V, with VCE(sat) ≤ 0.5 V at IC = 2.0 A / IB = 200 mA - suited for low-voltage switching and linear amplification in industrial control interfaces.
For engineers reviewing the MPS650RLRAG datasheet, pinout, applications, or equivalent options, key selection criteria include verified DC current gain stability across temperature (−55°C to +150°C), safe operating area (SOA) compliance per Figure 7, Pb-free TO-92 packaging, and tape-and-reel delivery format (2000 units/reel).
Technical Context
The MPS650RLRAG operates as a silicon NPN bipolar junction transistor optimized for medium-current linear amplification and saturated switching. Its design supports VCB = 60 V, VEB = 5.0 V, and thermal resistance RθJA = 200°C/W - enabling use in ambient-temperature-limited PCB layouts without forced cooling. The device exhibits fT = 75 MHz at IC = 50 mA, confirming suitability for audio-frequency and low-speed digital signal buffering.
It shares the same die and electrical characteristics as the bulk-packaged MPS650G but differs exclusively in packaging format: MPS650RLRAG is supplied in Pb-free TO-92 tape-and-reel (2000 units), with bent leads and orientation per marking diagram (EMITTER–BASE–COLLECTOR, pins 1–2–3). No internal biasing, protection diodes, or integrated resistors are present.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 40 V - Maximum collector-emitter voltage before breakdown under open-base conditions; defines upper rail limit in switch-mode or amplifier stages. |
| IC (continuous) | 2.0 A - Sustained collector current capability at TA = 25°C; requires derating above 25°C (5.0 mW/°C) for ambient-limited operation. |
| hFE | ≥75 at IC = 50 mA - Minimum DC current gain ensures reliable base drive sizing for switching applications with margin. |
| VCE(sat) | ≤0.5 V at IC = 2.0 A / IB = 200 mA - Low saturation voltage minimizes conduction loss in high-current switching nodes. |
| fT | 75 MHz - Transition frequency confirms usable bandwidth up to ~10 MHz for small-signal amplification with stable gain. |
| TJ range | −55°C to +150°C - Extended junction temperature rating supports deployment in automotive engine compartments and industrial enclosures. |
Pinout & Package
Package: TO-92 (Case 29-11), Pb-free, straight or bent lead options; body dimensions per datasheet page 4 (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 sink terminal | Reference node for base-emitter biasing; connects to ground or low-side return path in common-emitter configurations. |
| 2 (Base) | Control input | Receives forward-biased current to modulate collector current; requires external series resistor to limit IB per hFE and load requirements. |
| 3 (Collector) | Current source terminal | Delivers amplified output current; connects to load and supply rail in switching or active-load amplifier topologies. |
Key Features
| Feature | Design Value |
|---|---|
| Pb-free TO-92 packaging | Complies with RoHS Directive 2011/65/EU and JEDEC J-STD-020 reflow profiles; suitable for automated SMT assembly with tape-and-reel feed. |
| High hFE consistency | Minimum hFE ≥ 75 maintained across IC = 50 mA to 2.0 A (per Fig. 1), reducing base drive variability in production designs. |
| Robust SOA | Validated safe operating area up to 2.0 A / 40 V (DC) with second-breakdown immunity per Figure 7 - enables reliable operation in inductive load switching. |
| Low VBE(on) | ≤1.0 V at IC = 1.0 A - reduces base drive voltage headroom requirement in 3.3 V or 5 V logic-controlled circuits. |
Applications
| Industrial Relay Drivers | DC Motor Control Stages |
|---|---|

Use Value: hFE ≥ 75 at IC = 50 mA guarantees stable loop gain and transient response under varying load conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN amplifier transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBT650LT1G | SOT-23 package (3-pin), 1.0 A IC, VCEO = 40 V, hFE ≥ 100 @ 10 mA - smaller footprint, lower current rating. | Not suitable for 2.0 A loads; preferred where board space is constrained and current demand ≤ 1.0 A. | Select MMBT650LT1G only when SMT density outweighs current capacity needs and thermal management permits lower PD. |
| BC547B | TO-92 package, VCEO = 45 V, IC = 100 mA, hFE = 200–450 - higher gain but 20× lower current rating. | Restricted to signal-level amplification; cannot replace MPS650RLRAG in power-switching roles. | Choose BC547B for low-noise preamp stages where gain linearity matters more than current delivery. |
Compared with MMBT650LT1G and BC547B, the MPS650RLRAG uniquely balances 2.0 A current handling, TO-92 through-hole compatibility, and validated SOA - making it irreplaceable in cost-sensitive, medium-power industrial switching where SMT thermal limits or gain-only optimization are insufficient.

FAQ
What is the maximum continuous collector current rating for the MPS650RLRAG?
The MPS650RLRAG is rated for 2.0 A continuous collector current at ambient temperature (TA = 25°C). This rating assumes free-air convection cooling; derating is required at higher ambient temperatures - 5.0 mW/°C above 25°C - and must be validated against actual PCB layout and thermal environment using the device's RθJA = 200°C/W specification.
Does the MPS650RLRAG have built-in protection features such as ESD clamping or thermal shutdown?
No, the MPS650RLRAG is a bare-die NPN bipolar transistor with no integrated protection circuitry. It lacks ESD protection diodes, thermal shutdown, or current limiting. External components - including base current limiting resistors, flyback diodes for inductive loads, and heatsinking - must be implemented per the application's voltage, current, and thermal requirements as defined in the onsemi MPS650/D datasheet.
Can the MPS650RLRAG be used as a direct replacement for the MPS650G in existing designs?
Yes, the MPS650RLRAG is electrically identical to the MPS650G and shares the same silicon die, absolute maximum ratings, and electrical characteristics. The only difference is packaging format: MPS650RLRAG is supplied in Pb-free TO-92 tape-and-reel (2000 units), while MPS650G is bulk-packed (5000 units). Pinout, marking, and mechanical dimensions are fully compatible.
What is the typical DC current gain (hFE) of the MPS650RLRAG at 1.0 A collector current?
Per the onsemi MPS650/D datasheet, the MPS650RLRAG guarantees hFE ≥ 75 at IC = 50 mA and VCE = 2.0 V. At IC = 1.0 A, the minimum hFE drops to ≥ 75 (same guaranteed value), though typical performance may vary. Designers should verify gain behavior at 1.0 A using Figure 1 and apply appropriate base drive margin to ensure saturation under worst-case conditions.
Is the MPS650RLRAG suitable for high-frequency switching applications above 10 MHz?
The MPS650RLRAG has an fT of 75 MHz, indicating usable small-signal gain up to approximately 10 MHz. However, its SOA and switching speed (limited by minority-carrier storage time) make it unsuitable for high-efficiency, high-frequency (>100 kHz) PWM power conversion. It is best applied in low-to-moderate frequency switching (e.g., relay control, motor enable/disable) or audio-band amplification where bandwidth and gain stability are prioritized over switching speed.
