Overview
The Panjit International Inc. 1N4733A_R2_00001 is a silicon Zener diode from the 1N4728A series, designed for voltage regulation and clipping applications. It features a nominal Zener voltage of 5.1 V with a tolerance range of 4.8 V to 5.4 V at a test current of 49 mA. The device has a maximum power dissipation of 1 W and operates within a temperature range of -55°C to +150°C. Electrical characteristics include a maximum dynamic impedance of 7 Ω at the test current and a maximum leakage current of 10 µA at 1 V reverse voltage. It utilizes a DO-41 molded plastic case with axial leads.
Feature Summary
- Utilizes a low-inductance design suitable for standard voltage regulation tasks
- Constructed with UL 94V-O rated flame-retardant epoxy in a DO-41 package
- Supports high-temperature soldering conditions at 260°C for ten seconds
Applications
- Voltage stabilization circuits
- Signal clipping and limiting applications
- General-purpose discrete semiconductor protection
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details, as suffixes may indicate variations in reel or bulk quantities. Confirm RoHS compliance status and lead-free terminal specifications directly with the manufacturer's latest datasheet revision before finalizing procurement orders.
Selection Notes
Select this component when a 5.1 V reference point is required with a 1 W power rating. Ensure the application environment remains within the specified -55°C to +150°C junction temperature limits. Verify that the 7 Ω dynamic impedance meets the circuit's stability requirements under varying load currents.
Part Context
This part belongs to the 1N47xxA series of 1 Watt Zener diodes manufactured by Panjit International Inc. The series covers a wide voltage range from 3.3 V to 68 V, all sharing the same DO-41 axial leaded package and general mechanical construction standards defined in the 1N4728A series datasheet.
Replacement Considerations
Cross-reference with other manufacturers' 1N4733A parts for pin-compatible replacements. Verify that substitute components meet the identical 5.1 V nominal voltage, 1 W power dissipation, and DO-41 package dimensions to ensure physical and electrical interchangeability.
