Overview
The Central Semiconductor Corp 1N4685 TR TIN/LEAD is a unidirectional silicon voltage regulator diode housed in the DO-35 package. It features a nominal Zener voltage of 3.6 V and a power dissipation rating of 0.5 W at +50°C. The device utilizes double plug construction with metallurgically bonded elements for reliability. Electrical characteristics include a maximum forward voltage of 1.1 V at 200 mA. Operating temperatures range from -65°C to +175°C, with storage capabilities matching this span. DC power derating applies above +50°C.
Feature Summary
- Metallurgically bonded internal construction
- Double plug design for structural integrity
- Silicon unidirectional voltage regulation
Applications
- Voltage reference circuits
- Overvoltage protection
- General purpose clipping applications
Procurement Notes
Verify the specific suffix 'TR' against official datasheets to confirm tape-and-reel packaging versus bulk options. Confirm tin/lead plating compliance if RoHS requirements apply. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability before procurement.
Selection Notes
Select this component when a 3.6 V regulation point is required in a through-hole DO-35 form factor. Consider the 0.5 W power rating and thermal derating curves for high-temperature environments. Ensure the operating temperature range meets system specifications given the wide -65°C to +175°C capability.
Part Context
This part belongs to the standard 1N4685 series of Zener diodes manufactured by Central Semiconductor. It shares electrical characteristics with other manufacturers' equivalents but may differ in physical construction details such as the metallurgical bonding process. The tin/lead finish indicates a specific terminal plating option available within their product line.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Generic equivalents may vary in impedance or leakage current despite matching voltage ratings.
