Single Zener Diodes Procurement Notes

Verify the manufacturer origin, as the datasheet identifies Microsemi Scottsdale Division while the brand is listed as Microchip Technology. Confirm the specific suffix requirements if RoHS compliance or internal metallurgical bonding is required for the application. Ensure the ordering part number matches the exact voltage tolerance needed, as the B suffix denotes the standard 5% tolerance.

Single Zener Diodes Selection Notes

Select this component when a stable reference voltage near 13 V is required in through-hole designs. The wide operating temperature range supports harsh environments. Consider the low capacitance for applications sensitive to signal integrity. Verify that the 500 mW steady-state power rating aligns with the thermal management capabilities of the target PCB layout.

Single Zener Diodes Part Context

This component belongs to the 1N957B through 1N992B series of 0.5 W Zener Voltage Regulators. The series offers a selection from 6.8 to 200 volts with various tolerance options. These devices are JEDEC registered and utilize a DO-35 package, providing flexible axial-lead mounting terminals for standard printed circuit board assembly.

Single Zener Diodes Replacement Considerations
