1N5246CRL

Single Zener Diodes Overview

The Motorola 1N5246CRL is a silicon unidirectional Zener voltage regulator diode designed for through-hole mounting. It features a DO-35 (DO-204AH) glass axial-leaded package with a total power dissipation of 500 mW. The device provides a nominal Zener voltage of 16 V with a tight tolerance of ±2%. Key electrical characteristics include a maximum reverse leakage current of 100 nA and a Zener impedance of 17 Ohms at a test current of 7.8 mA. It operates within a junction temperature range of -65 °C to +200 °C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction for environmental stability
• Epitaxial planar silicon design for consistent regulation
• High thermal stability across extended operating temperatures

Single Zener Diodes Applications

• Precision voltage reference circuits
• Overvoltage protection in sensitive electronics
• Voltage clamping applications

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as the 1N5246CRL suffix may indicate a specific tape-and-reel or legacy distribution format distinct from standard bulk packaging. Confirm RoHS compliance status and lead finish specifications against the latest datasheet from the current supplier, as historical Motorola parts may vary in regulatory adherence depending on the production era and subsidiary handling the inventory.

Single Zener Diodes Selection Notes

Select this component when a 16 V regulation point with tighter than standard 5% tolerance is required. The 2% tolerance variant ensures higher precision compared to the 1N5246B series. Ensure the circuit design accommodates the 500 mW power limit and that the DO-35 package dimensions fit the available PCB real estate for axial leads.

Single Zener Diodes Part Context

This part belongs to the JEDEC-registered 1N52xxB/C series of 500 mW Zener diodes. Originally developed by Motorola Semiconductor Products Inc., these components are widely recognized standards in the industry. The 'C' suffix typically denotes a tighter voltage tolerance band compared to the standard 'B' suffix, offering improved accuracy for critical analog applications requiring stable reference voltages.

Single Zener Diodes Replacement Considerations

Direct functional equivalents include the 1N5246B (±5% tolerance) and 1N5246D (±10% tolerance). Surface-mount replacements such as the MVMLL5246A or BZX55C16V offer similar electrical performance in compact packages. Verify pinout compatibility and thermal derating requirements when substituting.
