1N3035B-1/TR

Overview

The Microchip Technology 1N3035B-1/TR is a 43 V Zener diode with ±5% voltage tolerance, housed in a hermetically sealed DO-41 glass package. It features a maximum DC power dissipation of 1 W and operates within a junction temperature range of -55 °C to +175 °C. The device exhibits a maximum dynamic impedance of 70 Ohms at a test current of 6.0 mA and maintains a reverse leakage current of no more than 10 µA at 32.7 V. This component provides stable voltage regulation across broad operating conditions.

Feature Summary

• Hermetically sealed glass construction for high-reliability environments
• Stable voltage regulation over wide temperature ranges
• Low reverse leakage current characteristics

Applications

• Voltage reference circuits
• Overvoltage protection systems
• Precision voltage regulators

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm tape-and-reel packaging availability. Confirm RoHS compliance status as it varies by grade. Ensure the requested quantity matches factory reel specifications. Validate that the JAN, JANTX, or commercial qualification level meets project requirements before finalizing procurement orders.

Selection Notes

Select this component when a 43 V breakdown voltage with tight tolerance is required. Consider the DO-41 through-hole package for standard board layouts. Evaluate thermal derating curves if operating near maximum power limits. Verify radiation hardness requirements against MIL-PRF-19500/115 qualifications if applicable to the mission profile.

Part Context

This part belongs to the established 1N3016B-1 through 1N3045B-1 series of 1 Watt Zener diodes. The series offers JEDEC registered numbers with options for JAN, JANTX, and JANTXV military qualifications. The 1N3035B-1 specifically targets applications requiring a 43 V nominal breakdown with robust environmental sealing.
