Overview
The Central Semiconductor Corp 1N5306 TR TIN/LEAD is a silicon current regulator diode designed for stable current limiting applications. It features a nominal regulating current of 2.2 mA and a maximum limit voltage of 1.95 V. The device supports a maximum repetitive peak reverse voltage of 100 V and handles a maximum power dissipation of 0.5 W. Housed in an axial-leaded package, it operates within a standard temperature range typical for this component class.
Feature Summary
- Provides constant current regulation over a broad voltage range
- Functions as a counterpart to Zener diodes by regulating current rather than voltage
- Utilizes a double-plug internal bond connection for unique current limiting functionality
Applications
- Current limiting circuits
- Constant current sources
- Biasing networks for transistors or LEDs
Procurement Notes
Verify the specific suffix 'TR' against the manufacturer's official datasheet to confirm if it denotes tape-and-reel packaging or a specific lead finish variant. Ensure the tin/lead composition aligns with project compliance requirements. Cross-reference the part number with Central Semiconductor documentation to confirm availability and exact electrical tolerances before procurement.
Selection Notes
Select this component when a fixed current source is required across varying voltage conditions. Compare the 2.2 mA nominal current against circuit load requirements. Verify that the 100 V reverse voltage rating exceeds the maximum potential reverse bias in the application. Consider thermal management for the 0.5 W power dissipation capability.
Part Context
This part belongs to the 1N5283-1 through 1N5314-1 series of 0.5 watt current regulators produced by Microsemi (now part of Microchip). These devices are qualified per MIL-PRF-19500/463 for JAN, JANTX, JANTXV, and JANS levels, offering standard 10% tolerance options ranging from 0.22 mA to 4.7 mA.
Replacement Considerations
Direct substitutes include other parts from the 1N53xx series with identical 2.2 mA ratings. Verify pinout compatibility and package style (DO-7 or DO-35) when replacing. Ensure the replacement maintains the same dynamic impedance and leakage current specifications for critical applications.
