Overview
The onsemi 2SD826G is a silicon NPN epitaxial planar power transistor designed for high-current switching applications. It features a collector-emitter voltage rating of 50V and a continuous collector current capacity of 12A. The device is housed in a PCP (Power Compact Package) surface-mount package, facilitating automated assembly and space-constrained designs. Key electrical characteristics include a low saturation collector-to-emitter voltage and wide safe operating area (ASO), ensuring robust performance against breakdown conditions during switching transitions.
Feature Summary
- Low-saturation collector-to-emitter voltage for efficient conduction
- Wide Safe Operating Area (ASO) providing high resistance to breakdown
- PCP surface-mount package enabling downsizing and automated insertion
Applications
- Relay drivers
- High-speed inverters
- General high-current switching applications
Procurement Notes
Verify the specific suffix 'G' against the manufacturer's official datasheet to confirm lead-free and RoHS compliance status. Ensure the PCP package dimensions match your PCB footprint requirements. Confirm availability as older generation components may have limited production runs or obsolescence notices from onsemi.
Selection Notes
Select this component for applications requiring moderate voltage handling with high current switching capabilities in a compact form factor. The wide ASO makes it suitable for inductive loads where transient energy absorption is critical. Compare thermal resistance values against your heat dissipation strategy to ensure junction temperature limits are not exceeded under maximum load conditions.
Part Context
This part belongs to onsemi's lineup of general-purpose power transistors. It serves as a discrete alternative to integrated driver stages in medium-power circuits. The PCP package offers a balance between thermal performance and board space efficiency compared to traditional through-hole packages like TO-220.
Replacement Considerations
Consult onsemi documentation for direct pin-compatible substitutes within the same voltage and current class. Verify that any replacement maintains the PCP package outline and thermal characteristics to avoid PCB redesign.
