1N5237B-TP

Single Zener Diodes Overview

The 1N5237B-TP is a single silicon Zener diode manufactured by Micro Commercial Components (MCC). It provides an 8.2 V nominal Zener voltage with a ±5% tolerance, designated by the 'B' suffix. The device operates in a DO-35 axial through-hole package and supports a DC power dissipation of 500 mW. Key electrical parameters include a maximum reverse leakage current of 3 µA at 6.5 V, a Zener impedance of 8 Ohms at a test current of 20 mA, and a positive temperature coefficient of +0.062 %/°C.

Single Zener Diodes Feature Summary

• Utilizes a glass encapsulation package designed for high-temperature soldering capabilities up to 260°C for 10 seconds.
• Features a wide voltage range availability across the series, supporting diverse circuit regulation requirements.

Single Zener Diodes Applications

• Voltage reference circuits requiring stable 8.2 V levels
• Overvoltage protection in electronic systems
• General-purpose voltage regulation

Single Zener Diodes Procurement Notes

Verify component authenticity by purchasing directly from MCC or authorized distributors to ensure traceability and quality standards. Confirm that the specific ordering suffix matches the required packaging format, as variations exist between tape-and-reel, ammo packing, and bulk carton configurations. Ensure compliance with RoHS directives and check for any lead-in-glass exemptions applicable to the specific manufacturing batch.

Single Zener Diodes Selection Notes

Select this component when a through-hole 500 mW Zener diode with an 8.2 V breakdown is required. The DO-35 package suits standard PCB mounting techniques. Consider the positive temperature coefficient for thermal stability analysis. Verify that the 8 Ohm dynamic impedance meets the noise and regulation specifications of the target application circuit.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5267B series of 500 mW Zener diodes produced by Micro Commercial Components. The series covers a broad spectrum of voltages from 2.4 V to 75 V. The 1N5237B specifically targets the mid-range voltage segment within this standardized product line.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N5237B variants meeting identical 8.2 V, 500 mW, and DO-35 specifications. Cross-reference datasheets to confirm matching Zener impedance and leakage current limits before implementation.

Single Zener Diodes FAQ

What does the 'B' suffix indicate for this component?

The 'B' suffix designates a 5% tolerance on the nominal Zener voltage.

Is this component suitable for surface mount applications?

No, the 1N5237B-TP utilizes a DO-35 axial through-hole package and is not designed for surface mount installation.
