1N5335B

Single Zener Diodes Overview

The onsemi 1N5335B is a single-channel Zener voltage regulator diode featuring a nominal reverse Zener voltage of 3.9 V with a ±5% tolerance. It operates within a maximum steady-state power dissipation of 5 W and supports an operating temperature range from -65°C to +200°C. The device utilizes silicon-oxide passivated junctions housed in a DO-15 axial lead plastic package (Case 017AA). Key electrical parameters include a test current of 320 mA, a maximum dynamic impedance of 2 Ω at the test current, and a maximum reverse leakage current of 50 μA.

Single Zener Diodes Procurement Notes

Verify that the ordered part number matches the specific suffix requirements, such as 'G' for Pb-Free packages or 'RL' for tape and reel shipping configurations. Confirm the manufacturer source directly from official documentation to ensure authenticity. Review the datasheet for handling instructions regarding soldering temperatures and mounting positions to maintain device reliability during assembly.

Single Zener Diodes Selection Notes

Select this component when a precise 3.9 V regulation point is required with tight tolerance limits. Ensure the application environment stays within the specified thermal derating curves to prevent exceeding the 5 W power dissipation limit. Consider the axial lead configuration for through-hole mounting needs and verify that the surge rating meets the transient energy requirements of the target circuit.

Single Zener Diodes Part Context

This device belongs to the 1N53 Series of 5 Watt Surmetic 40 Zener Voltage Regulators produced by onsemi. The series covers a wide voltage range from 3.3 V to 200 V, offering consistent performance across various voltage ratings. The 1N5335B specifically addresses low-voltage regulation applications within this robust family of axial lead diodes designed for general-purpose use.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N5335B variants that meet the same JEDEC specifications. Verify that alternative sources provide identical mechanical dimensions for Case 017AA and match the electrical parameters for voltage, impedance, and power dissipation.
