1N5354BG

Overview

The onsemi 1N5354BG is a silicon-oxide passivated Zener voltage regulator diode from the 1N53 Series. It provides a nominal reverse Zener voltage of 17 V with a tolerance of ±5%. The device operates in an axial lead Surmetic 40 (CASE 017AA) plastic package and supports a maximum steady-state power dissipation of 5 W at a lead temperature of 25°C. It features a junction-to-lead thermal resistance of 25 °C/W, a maximum operating junction temperature of 150 °C for DC conditions, and an ESD rating exceeding 16 kV per the Human Body Model.

Feature Summary

• Utilizes silicon-oxide passivated junctions to ensure tight electrical limits and superior operating characteristics.
• Features a void-free, transfer-molded thermosetting plastic case that offers corrosion resistance and environmental protection.
• Includes polarity indication via a cathode band and allows mounting in any position.

Applications

• Voltage regulation circuits requiring stable reference voltages
• Overvoltage protection systems utilizing surge current handling capabilities
• Temperature compensation networks leveraging specific voltage coefficients

Procurement Notes

Verify the ordering suffix 'G' confirms Pb-Free packaging availability as specified in the datasheet. Confirm the package type matches the Axial Lead CASE 017AA outline. Ensure the component meets the required JEDEC registration standards for the 1N53 series. Validate that the application environment remains within the specified thermal and voltage ratings.

Selection Notes

Select this component when a precise 17 V regulation point is required with high reliability. The 5 W power rating accommodates significant heat dissipation when adequate lead length is maintained. Consider the ±5% tolerance for applications demanding strict voltage accuracy. Evaluate the thermal resistance characteristics against the expected ambient temperatures and duty cycles.
