1N5358BRL

Overview

The onsemi 1N5358BRL is a 5 Watt Zener diode from the 1N53 Series, housed in an axial lead Surmetic 40 plastic package (Case 017AA). It features silicon-oxide passivated junctions for superior environmental protection. The nominal Zener voltage is 22 V with a tolerance of ±5%. Key electrical parameters include a maximum Zener impedance of 3.5 Ω at IZT = 50 mA and a reverse leakage current of 0.45 mA at VR = 16.7 V. The device supports a maximum DC Zener current of 216 mA and withstands surge currents up to 180 W for 8.3 ms pulses.

Feature Summary

• Utilizes silicon-oxide passivated junction technology for enhanced reliability and operating characteristics.
• Encased in void-free, transfer-molded thermosetting plastic providing corrosion resistance and solderability.
• Offers high ESD protection rated at Class 3 (>16 kV) per the Human Body Model.
• Guarantees maximum limits on multiple electrical parameters including voltage, impedance, and leakage.

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in analog circuits

Procurement Notes

Verify the specific ordering suffix 'RL' corresponds to the tape and reel packaging configuration containing 4000 units per reel. Confirm that the 'G' suffix is included if lead-free compliance is required, as standard packages may vary. Ensure the procurement documentation references the correct datasheet revision and mechanical outline Case 017AA to match physical footprint requirements.

Selection Notes

Select this component when a precise 22 V reference or regulation point is needed within a 5 Watt power dissipation envelope. The ±5% tolerance suits applications requiring moderate precision without tight binning costs. Consider the axial lead format for through-hole mounting where space allows, and verify thermal management capabilities given the junction-to-lead thermal resistance specifications under steady-state conditions.

Part Context

This part belongs to the 1N53 Series of 5 Watt Zener regulators, designed for general-purpose voltage control. The series spans voltages from 3.3 V to 200 V, offering a broad selection for various circuit needs. The 1N5358B specifically targets the 22 V range, providing a balance between low-voltage noise and high-voltage handling within the same standardized package family.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N5358B equivalents meeting the same 22 V, 5 W, ±5% specification. Verify that alternative parts maintain the same axial lead spacing and case dimensions (Surmetic 40) for direct board replacement. Ensure thermal and electrical ratings match or exceed the original device's limits for safe operation.
