Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm lead-free status and packaging type. Ensure compatibility with standard SOT-23 footprint requirements during procurement planning. Confirm that the requested quantity aligns with distributor reel specifications. Cross-reference datasheet revision dates to ensure access to the most current electrical parameters and mechanical outlines before finalizing orders.

Selection Notes

Select this component when designing circuits requiring a programmable unijunction transistor in a compact surface-mount form factor. Consider the 167 mW power dissipation limit and thermal resistance of 450 °C/W when determining heat sinking needs on FR-4 PCBs. Evaluate the maximum voltage ratings of 40 V for both gate-cathode and anode-cathode terminals to ensure adequate margin for the intended application voltage levels.
