Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'R' against official Sanyo documentation to confirm pinout and thermal characteristics differ from similar variants like the 'CA'. Ensure the supplier provides traceable datasheets confirming the 12A rating and TO-3P or equivalent flange package dimensions. Cross-reference the manufacturer's latest revision history to avoid obsolete stock.

Single Bipolar Transistors Selection Notes

Select this component when designs require a PNP transistor capable of handling 12A continuous current with a 50V voltage rating. The flange mount package is essential for applications where board-mounted packages cannot dissipate the required 45W of heat. Verify that the circuit base drive can support the specified hFE range for adequate saturation.

Single Bipolar Transistors Part Context

This part belongs to the Sanyo power transistor family, specifically engineered for high-power discrete applications. It serves as a rugged alternative to integrated modules in scenarios requiring discrete component flexibility. The manufacturer focuses on reliability for industrial environments, positioning this device within their portfolio of heavy-duty switching components.

Single Bipolar Transistors Replacement Considerations

Check for direct equivalents such as the 2SB1508Q series if package compatibility allows. Verify that any substitute matches the 12A current limit and 50V breakdown voltage exactly. Ensure the replacement also offers a flange mount configuration to maintain existing thermal interface designs.
