Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'DTZ' against official Renesas documentation to confirm exact mechanical dimensions and tape-and-reel specifications, as datasheets may list 'CTZ' or generic variants. Confirm RoHS compliance status directly with the manufacturer, as historical data indicates varying environmental compliance levels for this series. Ensure the ordering part number matches the required packaging format for your assembly line.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with 80V breakdown and 1A continuous current capability is required in a compact through-hole form factor. Consider the 140MHz transition frequency for high-speed switching needs. Compare thermal resistance values if operating near the 900mW power limit. Verify that the TO-92MOD footprint aligns with the target PCB design constraints.

Single Bipolar Transistors Part Context

This component belongs to the Renesas 2SB series of small-signal PNP transistors. These devices are widely used in consumer electronics and industrial control systems. The series offers a balance of current handling and voltage ratings suitable for low-to-medium power applications. Renesas continues to support these legacy components for long-term manufacturing stability.
