Single Bipolar Transistors Procurement Notes

Verify the specific hFE rank marking on the component body against Table 1 in the datasheet to confirm gain binning. Confirm compliance with EU RoHS Directive requirements before integration into regulated equipment. Contact Sanken Electric sales representatives to discuss suitability for applications requiring higher reliability than standard general-purpose electronics.

Single Bipolar Transistors Selection Notes

Select this component when a PNP power transistor with a -230 V rating and -15 A continuous current capability is required. Ensure the thermal design accommodates the 0.96 °C/W junction-to-case thermal resistance. Verify that the application does not involve aerospace, nuclear, or Class III medical devices, as these are excluded from the intended use scope.
