1N5366BRL

Overview

The onsemi 1N5366BRL is a 5 Watt Zener voltage regulator diode belonging to the 1N53 series. It features a nominal Zener voltage of 39 V with a ±5% tolerance, tested at a current of 30 mA. The device exhibits a maximum Zener impedance of 14 Ω and a reverse leakage current of 500 nA. Housed in an axial lead DO-15 (Case 017AA) plastic package, it supports a maximum steady-state power dissipation of 5 W and operates within a temperature range of -65°C to +200°C.

Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics and tight electrical limits.
• Provides high surge capability rated up to 180 W for 8.3 ms pulses.
• Features robust ESD protection meeting Class 3 standards exceeding 16 kV per the Human Body Model.

Applications

• Voltage regulation across broad operating currents and temperatures
• Protection against transient overvoltage events
• Reference voltage generation in electronic circuits

Procurement Notes

Verify that the ordering suffix 'RL' corresponds to the tape and reel packaging format containing 4000 units per reel. Confirm the presence of the 'G' suffix if lead-free compliance is required, as standard packages may differ. Ensure the specific part number matches the exact voltage rating and impedance requirements for the target application circuit design.

Selection Notes

Select this component when a 39 V reference point is required with a 5 W power handling capacity. The axial lead configuration facilitates through-hole mounting. Consider the thermal resistance characteristics and derating curves above 25°C ambient temperature to ensure reliable operation under continuous load conditions without exceeding junction temperature limits.

Part Context

This device is part of the 1N53 series of 5 Watt Surmetic 40 Zener Voltage Regulators manufactured by onsemi. The series offers a wide selection of voltages ranging from 3.3 V to 200 V. These components are designed for applications requiring high reliability and protection in common environmental conditions using transfer-molded plastic packages.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N5366B equivalents or generic 5W Zener diodes with matching 39V nominal voltage and ±5% tolerance. Verify that replacement parts meet the same 14 Ω impedance and 500 nA leakage specifications to maintain circuit performance integrity.
