Product details
Overview
MPS6724RLRAG from onsemi is an NPN silicon Darlington transistor in a TO-92 package, rated for 1.0 W total device dissipation at TA = 25°C, 40 V collector-emitter breakdown voltage (V(BR)CES), and 1000 mA continuous collector current - used in low-frequency switching and driver stages for relays, lamps, and small solenoids.
For engineers reviewing the MPS6724RLRAG datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, thermal limits, safe operating area boundaries, DC current gain behavior across temperature and current, and Pb-free tape-and-reel packaging details specific to the MPS6724RLRAG variant.
Technical Context
The MPS6724RLRAG integrates two cascaded NPN transistors in a monolithic Darlington configuration, delivering high DC current gain (hFE ≥ 25,000 at IC = 200 mA, VCE = 5 V) with low base drive requirements. Its safe operating area is constrained by thermal limit (2.5 W at TC = 25°C), second breakdown, and current limit - not rated for RF or high-speed switching above 100 MHz.
It operates across −55°C to +150°C junction temperature range, with thermal resistance RJA = 125°C/W and RJC = 50°C/W. Saturation voltage reaches 1.5 V at IC = 1000 mA / IB = 2.0 mA, and VBE(on) is up to 2.0 V under same conditions - requiring careful base resistor sizing in linear or saturated switching designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)CES | 40 Vdc - maximum allowable collector-emitter voltage before breakdown under open-base condition; defines upper rail limit in switching applications |
| IC Continuous | 1000 mAdc - sustained load current capability without derating; requires heatsinking or forced airflow above ambient >25°C |
| PD @ TA=25°C | 1.0 W - power dissipation limit with no heatsink; derates 8.0 mW/°C above 25°C ambient |
| hFE (Min) | 25,000 at IC = 200 mAdc, VCE = 5.0 V - enables microampere-level base drive for 200 mA loads, reducing driver stage complexity |
| VCE(sat) | ≤1.5 Vdc at IC = 1000 mAdc, IB = 2.0 mAdc - determines conduction loss and heat generation in saturated switch mode |
| fT | 100–1000 MHz - small-signal bandwidth limit; usable only for low-frequency switching (≤10 kHz) due to Darlington phase delay and storage time |
Pinout & Package
Package: TO-92 (Case 29-10, Style 1), Pb-free, straight-lead configuration. Dimensions comply with ON Semiconductor mechanical drawing 98AON52857E.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter | Common emitter node; connects to ground or low-side return path; carries full load current |
| 2 | Base | Control input; requires current-limited drive (IB ≤ 2 mA typical for 1 A IC); sensitive to ESD |
| 3 | Collector | High-side output node; connects to load and supply rail; must be isolated from PCB ground plane if used in high-voltage switching |
Key Features
| Feature | Design Value |
|---|---|
| High DC current gain | hFE ≥ 25,000 at 200 mA - reduces base drive circuitry complexity and power consumption in discrete logic-level drivers |
| Low saturation voltage | VCE(sat) ≤ 1.5 V at 1 A - minimizes conduction loss and self-heating in relay/solenoid interface circuits |
| Pb-free TO-92 packaging | RoHS-compliant, tape-and-reel (2000 units/reel) - supports automated SMT assembly and environmental compliance programs |
| Wide operating temperature | −55°C to +150°C TJ - suitable for industrial control enclosures and automotive under-hood auxiliary modules |
Applications
| Relay Driver Circuit | Lamp Dimming Interface |

Use Scenario: Current-source output stage for 4–20 mA analog sensor transmitter in hazardous-area loop-powered design. IC Role / Device Role / Timing Role: Linear-mode current regulator with emitter-follower configuration; sets output current via precision sense resistor. Use Value: Stable hFE over −40°C to +85°C enables ±0.5% full-scale accuracy without active temperature compensation in field instruments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Darlington transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPS6724RLRA | Pb-containing TO-92 variant; identical electrical specs and pinout; non-RoHS compliant | Not suitable for EU/China RoHS-regulated end equipment; same thermal and switching performance | Select MPS6724RLRA only when legacy compliance or cost sensitivity overrides environmental requirements |
| ULN2003A | 7-channel Darlington array in SO-16; 500 mA per channel; integrated clamp diodes and TTL-compatible inputs | Replaces discrete single-Darlington where multi-load driving or logic-level interfacing is required | Choose ULN2003A for multi-relay boards; MPS6724RLRAG remains optimal for single high-current, low-cost, space-constrained nodes |
Compared with MPS6724RLRA and ULN2003A, the MPS6724RLRAG offers lowest unit cost and smallest footprint for single-load 1 A switching, while maintaining Pb-free compliance and proven reliability in industrial temperature cycling.

FAQ
What is the maximum continuous collector current rating for MPS6724RLRAG?
The MPS6724RLRAG is rated for 1000 mAdc continuous collector current at TA = 25°C. Derating is required above ambient temperature - 8.0 mW/°C - and actual usable current depends on PCB copper area, airflow, and thermal interface to ambient. At 70°C ambient, max continuous IC drops to approximately 640 mA based on RJA = 125°C/W.
Is MPS6724RLRAG pin-compatible with MPS6724RLRA?
Yes, the MPS6724RLRAG and MPS6724RLRA share identical TO-92 pinout (Emitter-Base-Collector on pins 1-2-3), mechanical dimensions, and electrical specifications. The only difference is Pb-free plating on MPS6724RLRAG versus leaded finish on MPS6724RLRA - making them direct drop-in replacements in layout.
Does MPS6724RLRAG include built-in protection features like flyback diodes?
No, the MPS6724RLRAG is a bare Darlington transistor without integrated protection. External flyback diodes must be added across inductive loads (e.g., relays, solenoids) to suppress VCE voltage spikes during turn-off. Its safe operating area (SOA) curve in Figure 1 assumes proper external clamping.
What is the typical DC current gain (hFE) of MPS6724RLRAG at 1 A collector current?
At IC = 1000 mAdc and VCE = 5.0 V, the MPS6724RLRAG has a minimum hFE of 4,000 per datasheet Table "ON CHARACTERISTICS". Typical values range from 6,000 to 12,000 depending on unit-to-unit variation and junction temperature - sufficient to achieve full saturation with ~250 µA base current.
Can MPS6724RLRAG be used in linear (analog) amplifier configurations?
The MPS6724RLRAG is not optimized for linear amplification due to limited fT bandwidth, high VBE(on), and significant thermal drift in hFE. It is characterized and qualified for switching and driver applications. For linear gain stages, consider dedicated low-noise NPN transistors such as MMBT3904 or BC847 series instead of MPS6724RLRAG.
