SMA6080

Overview

The SMA6080 is a PNP + NPN Darlington transistor array designed for three-phase motor drive applications. It integrates six complementary transistors with internal base resistors (R1: 4kΩ, R2: 100Ω, R3: 4kΩ, R4: 150Ω). The device features a maximum collector-emitter voltage of ±60V and a continuous collector current of ±2A. Peak collector current reaches ±4A with a pulse width under 1ms. Electrical characteristics include a DC current gain (hFE) ranging from 2000 to 12000 at ±1A. The component operates within a junction temperature range up to 150°C and utilizes a 12-SIP package.

Procurement Notes

Verify the specific manufacturer source document when sourcing this component. Confirm that the part status aligns with project timelines, as availability may vary. Ensure the procurement channel provides original manufacturer documentation to validate authenticity and technical specifications before integration into designs.

Selection Notes

Select the SMA6080 for applications requiring integrated high-gain switching in three-phase topologies. Evaluate thermal management requirements based on the specified junction-to-case thermal resistance. Verify that the internal resistor values match the driving circuit's output capabilities to ensure proper saturation and switching performance.

Part Context

This component belongs to Sanken Electric's lineup of power transistor arrays. It is functionally similar to other models in the series designed for motor control. The device consolidates multiple discrete components into a single package to reduce board space and assembly complexity in power electronics designs.

Replacement Considerations

Consult official datasheets for cross-reference data. Potential substitutes include other Sanken electric Darlington arrays such as SLA6020 or SLA6022, provided pinouts and electrical ratings are compatible.
