Procurement Notes

Verify the specific ordering suffix 'TIN/LEAD' when requesting plated devices from Central Semiconductor, as this designation indicates the required terminal finish. Confirm availability status directly with the manufacturer or authorized distributors, as lead times and stock levels vary. Ensure the reel packaging format matches your automated assembly requirements. Cross-reference the datasheet parameters against your circuit design constraints before finalizing procurement.

Selection Notes

Select this component when a precise, low-current regulation value near 0.38 mA is required within a 100 V potential range. The DO-35 package suits applications needing through-hole mounting. Consider the high dynamic impedance for stability in sensitive biasing roles. Evaluate thermal management capabilities given the 600 mW dissipation rating and extended temperature range for robust operation in demanding environments.
