1N5249B BK TIN/LEAD

Single Zener Diodes Overview

The Central Semiconductor Corp 1N5249B BK TIN/LEAD is a silicon unidirectional Zener diode with a nominal breakdown voltage of 19 V and a tolerance of ±5%. It features a maximum power dissipation of 0.5 W and operates within a temperature range of -65 °C to 200 °C. The device utilizes a DO-35 axial through-hole package with glass encapsulation and tin/lead terminal finishes.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a nominal 19 V breakdown point
• Constructed with silicon junction technology for reliable performance
• Designed for high-temperature operation up to 200 °C

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection stages
• Clipping and clamping applications

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix BK TIN/LEAD to confirm lead-free status compliance, as this variant indicates tin/lead plating which may not meet RoHS standards. Confirm the manufacturer is Central Semiconductor Corp and that the package matches the DO-35 specification. Ensure the voltage rating aligns with the 19 V requirement before procurement.

Single Zener Diodes Selection Notes

Select this component when a standard 19 V Zener voltage is required in an axial through-hole configuration. The 0.5 W power rating suits low-power regulation tasks. Verify compatibility with existing PCB footprints designed for DO-35 packages and ensure the operating environment supports the specified temperature range.

Single Zener Diodes Part Context

This part belongs to the 1N52xx series of Zener diodes manufactured by Central Semiconductor Corp. These components are widely used in general-purpose electronic circuits requiring precise voltage referencing or protection against transient overvoltages.

Single Zener Diodes Replacement Considerations

Direct substitutes include onsemi 1N5249B and Vishay MMSZ5249B-HE3-18. Verify pinout compatibility and electrical parameter equivalence before substitution.
