1N5276B-TP

Single Zener Diodes Overview

The MCC 1N5276B-TP is a single silicon Zener diode housed in a DO-35 glass axial leaded package. It provides a nominal Zener voltage of 150 V with a ±5% tolerance, indicated by the 'B' suffix. The device operates at a test current of 0.85 mA and dissipates up to 500 mW DC power. Key electrical parameters include a maximum reverse leakage current of 0.1 µA at 114 V, a Zener impedance (Zzt) of 1500 Ω, and a Zener impedance (Zzk) of 5000 Ω. The temperature coefficient is +0.110 %/°C.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix to confirm packaging format and compliance status. The '-TP' designation indicates Tape & Reel packaging containing 10,000 pieces per reel. Confirm that the 'B' suffix corresponds to the required ±5% voltage tolerance for your design specifications. Ensure the component meets environmental requirements regarding the lead-in-glass exemption if applicable to your manufacturing process.

Single Zener Diodes Selection Notes

Select this component when a precise 150 V reference is needed within a tight ±5% tolerance band. The DO-35 package suits through-hole applications where space allows. Consider the positive temperature coefficient for thermal stability analysis. Verify that the 500 mW power dissipation rating aligns with the expected operating conditions and derating curves provided in the datasheet.

Single Zener Diodes Part Context

This part belongs to the 1N5268 through 1N5276 series of 500 mW Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 82 V to 150 V. The 'B' suffix specifically denotes a tighter voltage tolerance compared to standard variants, ensuring higher precision for critical circuit applications.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 150 V Zener diodes in the DO-35 package. Ensure equivalent electrical parameters, particularly the 1500 Ω Zzt and 0.1 µA Ir limits. Verify that alternative parts support the same 500 mW power dissipation and operating temperature range.
