Procurement Notes

Verify the component authenticity by checking the manufacturer marking against official datasheet standards. Confirm the package type matches the SC-59 specification. Ensure the part number suffix aligns with the required tape and reel configuration for automated assembly processes. Cross-reference the date code with current production status to guarantee availability.

Selection Notes

Select this component when designing circuits requiring an NPN RF transistor with a 20V voltage rating. Consider the SC-59 package dimensions for PCB layout constraints. Evaluate the 150MHz operational limit against the target application frequency. Review the thermal management requirements associated with the small outline package for power dissipation limits.
