Product details
Overview
MPS6724G 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 motors.
For engineers reviewing the MPS6724G datasheet, pinout, applications, or equivalent options, key selection criteria include DC current gain (hFE ≥ 25,000 at IC = 200 mA), VCE(sat) ≤ 1.5 V at IC/IB = 1000 mA/2 mA, thermal resistance (RJA = 125°C/W), and Pb-free TO-92 packaging compliance.
Technical Context
The MPS6724G integrates two cascaded NPN transistors in a monolithic Darlington configuration, delivering high DC current gain with single-base control. It operates within −55°C to +150°C junction temperature range and supports safe operation up to 1000 mA under thermal-limited conditions.
Its electrical behavior is defined by VBE(on) ≤ 2.0 V at IC = 1000 mA, fT ≥ 100 MHz at IC = 200 mA, and Ccb ≤ 10 pF at VCB = 10 V - confirming suitability for medium-speed switching rather than RF or high-frequency amplification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)CES | 40 Vdc - maximum sustainable collector-emitter voltage before avalanche breakdown under open-base condition |
| IC (continuous) | 1000 mAdc - continuous collector current rating at TA = 25°C with derating above ambient |
| hFE (min) | 25,000 - minimum DC current gain at IC = 200 mAdc, VCE = 5.0 Vdc, enabling high-sensitivity base drive |
| VCE(sat) | ≤1.5 Vdc - saturation voltage at IC = 1000 mAdc, IB = 2.0 mAdc, limiting power loss in switching applications |
| RJA | 125 °C/W - junction-to-ambient thermal resistance, defining required heatsinking or PCB copper area for thermal management |
| fT | ≥100 MHz - current-gain bandwidth product at IC = 200 mAdc, VCE = 5.0 Vdc, f = 100 MHz, supporting ~100 kHz switching |
Pinout & Package
Package: TO-92 (Case 29-10, Style 1), Pb-free, through-hole mounting. Dimensions conform to ON Semiconductor mechanical drawing 98AON52857E.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter | Common emitter node for Darlington pair; connects to ground or low-side return path in switch configurations |
| 2 | Base | Input control terminal; drives both internal transistors; requires current-limiting resistor per hFE and load requirements |
| 3 | Collector | High-current output node; connects to load (e.g., relay coil or lamp anode) and supply rail via external pull-up |
Key Features
| Feature | Design Value |
|---|---|
| High DC current gain | hFE ≥ 25,000 enables microampere-level base drive for 1 A loads, reducing MCU GPIO burden |
| Low saturation voltage | VCE(sat) ≤ 1.5 V minimizes conduction loss and self-heating in 12 V/24 V industrial control outputs |
| Robust thermal rating | TJ range of −55°C to +150°C supports operation in automotive engine compartments and industrial enclosures |
| Pb-free TO-92 package | RoHS-compliant lead finish and marking "G" suffix ensure regulatory compliance without solderability compromise |
Applications
| Industrial Relay Drivers | Automotive Lamp Control |
|---|---|
Use Scenario: Driving 12 V/24 V electromagnetic relays in PLC I/O modules and motor starters. IC Role / Device Role / Timing Role: High-gain Darlington switch providing galvanic isolation between low-power logic and inductive load.

Use Value: VEBO = 12 V and TJ = −55°C to +150°C allow direct integration into unregulated battery-powered field devices. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Darlington transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBT6427LT1G | Lower V(BR)CES (30 V), lower hFE (10,000 min), SOT-23 package | Not suitable for 40 V bus rails; limited to low-voltage logic-level switching | Select only when space-constrained PCBs require SMT and voltage margin <30 V suffices |
| ULN2003A | 7-channel Darlington array, 500 mA per channel, built-in clamp diodes, SOIC-16 | Higher integration but fixed channel count; not a drop-in replacement for single-device designs | Choose when driving multiple loads (e.g., stepper motor phases or multi-relay banks) with shared logic interface |
Compared with MMBT6427LT1G and ULN2003A, the MPS6724G offers higher voltage tolerance and single-device flexibility for discrete high-current switching, while avoiding array overhead or SMT layout constraints.

FAQ
What is the maximum continuous collector current for the MPS6724G?
The MPS6724G supports a maximum continuous collector current of 1000 mAdc at TA = 25°C, with linear derating of 8.0 mW/°C above that ambient temperature. This rating assumes proper PCB copper area or heatsinking to maintain junction temperature within −55°C to +150°C limits. The MPS6724G must not be operated beyond its SOA boundary, especially under pulsed or inductive load conditions.
Does the MPS6724G have built-in protection diodes?
No, the MPS6724G does not integrate flyback or clamp diodes. When switching inductive loads such as relays or solenoids, an external freewheeling diode (e.g., 1N4004) must be connected across the load with cathode to VCC and anode to collector. This prevents voltage spikes exceeding V(BR)CES = 40 Vdc from damaging the MPS6724G during turn-off transitions.
Is the MPS6724G pin-compatible with the MPS6725G?
Yes, the MPS6724G and MPS6725G share identical TO-92 pinout (Emitter-Base-Collector, Style 1) and mechanical footprint, but differ in absolute maximum ratings: MPS6725G has V(BR)CES = 50 Vdc and VCBO = 60 Vdc versus 40 Vdc and 50 Vdc for the MPS6724G. Substitution is acceptable only if system voltage margins align with the lower rating of the MPS6724G.
What is the typical base-emitter on voltage for the MPS6724G?
The MPS6724G exhibits a maximum VBE(on) of 2.0 Vdc at IC = 1000 mAdc and VCE = 5.0 Vdc. Due to its Darlington structure, this represents the sum of two VBE drops (~1.4 V typical), resulting in higher base drive voltage requirement than single transistors. Designers must size base resistors accordingly to ensure sufficient IB for full saturation, especially at elevated temperatures.
Can the MPS6724G be used in linear amplifier applications?
The MPS6724G is not optimized for linear amplification. Its high hFE and relatively wide VCE(sat) spread make biasing unstable across temperature and current ranges. While small-signal fT ≥ 100 MHz suggests theoretical bandwidth, the device lacks specified linearity parameters (e.g., THD, distortion curves) and is characterized primarily for switching use. For amplification, dedicated small-signal transistors like 2N3904 or BC847 are recommended instead of the MPS6724G.
