1N5350BRL

Overview

The 1N5350BRL is a silicon unidirectional voltage regulator diode from the 1N53 Series, manufactured by onsemi. It features a nominal Zener voltage of 13 V with a ±5% tolerance range (12.35 V to 13.65 V) at a test current of 100 mA. The device provides a maximum steady-state power dissipation of 5 W and operates within a junction temperature range of -65°C to +200°C. It utilizes an axial lead plastic package (CASE 017AA-01/DO-41) and includes a polarity band to indicate the cathode.

Feature Summary

• Utilizes silicon-oxide passivated junctions for superior operating characteristics
• Features void-free, transfer-molded thermosetting plastic packaging
• Offers high surge rating capability up to 180 W at 8.3 ms pulse width
• Includes ESD protection rated at Class 3 (>16 kV) per Human Body Model

Applications

• Voltage regulation in electronic circuits
• Surge protection applications requiring high peak current handling
• General-purpose clipping and clamping circuits

Procurement Notes

Verify that the ordering suffix 'RL' corresponds to the tape and reel shipping configuration as specified in the manufacturer's documentation. Confirm RoHS compliance status based on the specific lot marking or datasheet revision, noting that 'G' suffix explicitly denotes Pb-Free packages while standard suffixes may vary. Ensure the component matches the CASE 017AA-01 mechanical outline for proper mounting.

Selection Notes

Select this component when a precise 13 V reference is required with tight manufacturing tolerances. The 5 W power rating supports higher current loads compared to lower-power variants. Consider the thermal resistance characteristics and derating requirements above 25°C ambient temperature to ensure reliable operation under continuous DC conditions without exceeding the maximum junction temperature limits.

Part Context

This part belongs to the 1N5333B through 1N5388B JEDEC registered series of 5 Watt Zener diodes. The series covers a wide voltage range from 3.3 V to 200 V, offering various tolerance options. The 1N5350BRL specifically addresses the mid-range voltage segment, providing robust performance in axial lead packages suitable for through-hole mounting in industrial and commercial electronics.

Replacement Considerations

Cross-reference with other manufacturers' 1N5350 equivalents ensuring identical 13 V nominal voltage, 5 W power rating, and DO-41 axial package dimensions. Verify electrical parameters such as impedance and leakage current match the original specifications.
