1N5388BRLG

Overview

The onsemi 1N5388BRLG is a single-channel Zener voltage regulator diode from the 1N53 Series, designed for high-power applications. It features a nominal reverse Zener voltage of 200 V with a ±5% tolerance and a maximum steady-state power dissipation of 5 W at 25°C. The device utilizes an axial lead DO-15 (Surmetic 40) plastic package suitable for through-hole mounting. Electrical characteristics include a test current of 5 mA, a maximum dynamic impedance of 480 Ω, and a maximum reverse leakage current of 500 nA at 152 V. It operates within a temperature range of -65°C to +200°C.

Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics and environmental protection.
• Features a void-free, transfer-molded thermosetting plastic package that is corrosion resistant and offers solderable leads.
• Provides robust surge handling capabilities with ratings up to 180 W for 8.3 ms pulses.
• Guarantees maximum limits on multiple electrical parameters including voltage, impedance, and leakage.

Applications

• Voltage regulation circuits requiring stable reference voltages in industrial equipment.
• Overvoltage protection stages for power supplies and transient suppression.
• High-reliability systems where tight voltage tolerances are required.

Procurement Notes

Verify the specific ordering suffix 'RLG' corresponds to the tape and reel packaging format containing 4000 units per reel, distinct from the bulk box configuration. Confirm RoHS compliance status as indicated by the 'G' suffix in official documentation. Ensure the procurement specification matches the exact 200V nominal voltage rating and 5W power dissipation requirements for the target application environment.

Selection Notes

Select this component when a precise 200V regulation point is needed with high power handling. The 5W dissipation capability requires adequate thermal management via lead length or heatsinking. Consider the 480Ω dynamic impedance for load regulation performance. Verify that the axial lead form factor fits the PCB layout constraints compared to surface mount alternatives.

Part Context

This part belongs to the 1N53 Series of 5 Watt Surmetic 40 Zener Voltage Regulators manufactured by onsemi. The series covers a wide voltage range from 3.3V to 200V, offering consistent mechanical and electrical specifications across all variants. The 1N5388BRLG specifically addresses the upper end of this voltage spectrum, providing a standardized solution for high-voltage regulation tasks.

Replacement Considerations

Direct substitutes include other manufacturers' 1N5388B devices meeting the same JEDEC outline and electrical specifications. Cross-reference with generic 1N5388 equivalents ensuring they support 5W power dissipation and 200V breakdown. Verify that any replacement maintains the axial lead package dimensions for mechanical compatibility.
