1N5386BRL

Overview

The onsemi 1N5386BRL is a single Zener voltage regulator diode from the 1N53 Series, housed in an axial lead Surmetic 40 (Case 017AA) plastic package. It features a nominal reverse Zener voltage of 180 V with a ±5% tolerance and a maximum steady-state power dissipation of 5 W at a lead temperature of 25°C. The device operates within a junction and storage temperature range of -65°C to +200°C. Key electrical characteristics include a test current of 5 mA, a maximum Zener impedance of 430 Ohms, and a maximum reverse leakage current of 0.5 µA at 130 V.

Feature Summary

• Utilizes silicon-oxide passivated junctions for improved operating characteristics and environmental protection.
• Offers high surge capability with ratings up to 180 W for non-repetitive pulses of 8.3 ms duration.
• Provides robust electrostatic discharge (ESD) protection rated at Class 3 (>16 kV) per the Human Body Model.
• Guarantees maximum limits on multiple electrical parameters including Zener voltage, impedance, and leakage current.

Applications

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

Procurement Notes

Verify that the ordering suffix 'BRL' corresponds to the tape and reel packaging format containing 4000 units per reel, distinct from the bulk box configuration. Confirm the presence of the 'G' suffix if lead-free compliance is required by the assembly process. Ensure the procurement documentation references the correct Case 017AA mechanical outline for mounting clearance.

Selection Notes

Select this component when a stable 180 V reference is needed with a 5 W power handling capacity. The axial lead design facilitates through-hole mounting in applications requiring high thermal stability. Consider the specific Zener impedance and leakage current specifications to ensure compatibility with low-noise circuit requirements.

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, utilizing transfer-molded plastic packages designed for durability. The 1N5386 variant specifically targets the 180 V segment of this lineup, offering standardized JEDEC tolerances.

Replacement Considerations

Cross-reference with other manufacturers' DO-15 or Surmetic 40 packaged Zener diodes rated for 180 V and 5 W. Verify that substitute parts meet the same ±5% voltage tolerance and thermal resistance specifications to maintain circuit performance integrity.
