1N5369BRL

Overview

The onsemi 1N5369BRL is a 5 Watt Zener voltage regulator from the 1N53 Series, housed in an axial lead Surmetic 40 (CASE 017AA) plastic package. It features silicon-oxide passivated junctions for superior environmental protection and tight electrical limits. The nominal Zener voltage is 51 V with a ±5% tolerance range of 48.45 V to 53.55 V at a test current of 25 mA. Maximum DC Zener current is 93 mA, with a maximum surge current rating of 230 A for 8.3 ms pulses. The device operates within a junction temperature range of -65°C to +200°C.

Feature Summary

• Silicon-oxide passivated junctions provide enhanced reliability and protection against common environmental conditions.
• Axial lead transfer-molded plastic package offers corrosion-resistant external surfaces and readily solderable leads.
• Guaranteed maximum limits on up to six electrical parameters ensure consistent performance across the series.

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage sources in measurement equipment

Procurement Notes

Verify the specific ordering suffix 'RL' corresponds to the tape and reel packaging configuration as defined in the official datasheet. Confirm that the 'G' suffix is included if lead-free compliance is required for the assembly process. Ensure the component marking matches the 1N5369B designation to validate the correct voltage rating and tolerance class before integration into production.

Selection Notes

Select this component when a 51 V Zener reference with 5 W power dissipation capability is required. The axial lead format suits through-hole mounting applications where mechanical stability is needed. Consider the thermal resistance characteristics and derating requirements above 25°C to ensure the junction temperature remains within safe operating limits during continuous operation.

Part Context

This part belongs to the 1N53 Series of 5 Watt Zener diodes manufactured by onsemi. The series covers a wide voltage range from 3.3 V to 200 V, all utilizing the same Surmetic 40 case outline. The 'B' suffix indicates a ±5% tolerance, distinguishing it from other tolerance variants within the broader 1N53 family.

Replacement Considerations

Direct substitutes must match the 51 V nominal voltage, 5 W power rating, and axial lead package dimensions. Verify equivalent Zener impedance and leakage current specifications to maintain circuit performance. Cross-reference with other manufacturers offering JEDEC-compliant 1N5369 equivalents ensuring identical thermal and electrical characteristics.
