Q8025NH6RP is listed in the Triacs range at ChipApex. The manufacturer field lists Littelfuse Inc.. Its product description is TRIAC ALTERNISTOR 800V 25A TO263. Review the specifications below when checking this part for your BOM.
The Littelfuse Q8025NH6RP is an Alternistor Triac rated for 800V repetitive off-state voltage and 25A RMS on-state current. It features a non-repetitive surge current capacity of 208A and maintains a low on-state voltage of 1.8V. The device operates within a temperature range of -40°C to +125°C, with a maximum holding current of 100mA. Triggering requires a gate voltage of 2.5V and current of 80mA. Leakage current is limited to 10µA at VDRM. Packaged in SMTO-263-2 (D2PAK) surface-mount format, it is supplied in reels.
Verify the specific suffix RP indicates reel packaging when sourcing. Confirm the 800V rating aligns with circuit requirements. Ensure compatibility with SMTO-263-2 footprints during layout. Check manufacturer documentation for RoHS compliance status prior to final selection.
Select this component for applications requiring high blocking voltage and moderate continuous current in a compact form factor. Compare trigger sensitivity against driver capabilities. Evaluate thermal management needs given the 25A RMS rating. Consider alternative voltage ratings if system transients exceed 800V.
This part belongs to the Qxx25xxHx series of Alternistor Triacs from Littelfuse. These devices are designed as solid-state switches for AC applications. The series offers various voltage ratings while maintaining consistent current handling and package dimensions for design flexibility across different power levels.
Q8025NH5RP is a documented substitute offering identical 25A current but higher 800V rating with different gate characteristics.
