1N5237B-G

Single Zener Diodes Overview

The Comchip Technology 1N5237B-G is an axial leaded glass Zener diode housed in a DO-35 package. It provides a nominal stabilizing voltage of 8.2 V at a test current of 20 mA, with a maximum dynamic impedance of 8 Ω and a maximum reverse leakage current of 3 µA. The device supports a power dissipation of 500 mW at 25°C, operating within a junction temperature range up to 175°C and a storage temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Axial leaded construction utilizing a glass DO-35 case for polarity indication via cathode band
• Provides stable voltage regulation across a wide operational temperature spectrum
• Compliant with RoHS environmental standards

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Over-voltage protection stages in electronic systems
• General-purpose clipping and clamping applications

Single Zener Diodes Procurement Notes

Verify the specific manufacturer designation when sourcing, as multiple vendors produce this standard part number. Confirm that the component meets required RoHS compliance specifications if mandated by your assembly process. Ensure the DO-35 through-hole package aligns with your PCB footprint design before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component for designs requiring a precise 8.2 V reference point with low dynamic impedance. The DO-35 package suits through-hole manufacturing processes. Evaluate thermal derating requirements carefully, as power dissipation capabilities decrease significantly as ambient temperatures exceed 50°C.

Single Zener Diodes Part Context

This device belongs to the 1N5221B-G through 1N5267B-G series of axial leaded glass Zener diodes manufactured by Comchip Technology. The series covers a broad voltage range from 2.4 V to 75 V, offering standardized packaging and electrical characteristics suitable for diverse discrete semiconductor applications.

Single Zener Diodes Replacement Considerations

Standard equivalents include the 1N5237B from manufacturers such as Microchip or NXP. Verify that substitute components maintain identical DO-35 mechanical dimensions and meet the same 500 mW power dissipation rating.
