Overview
The Microchip Technology 1N5529B/TR is a low voltage avalanche Zener diode with a nominal breakdown voltage of 9.1 V at a test current of 1 mA. It features a maximum dynamic impedance of 45 Ohms and a maximum reverse leakage current of 0.1 µA. The device operates within a temperature range of -65 °C to +175 °C and dissipates up to 500 mW. Packaged in an axial-lead DO-35 (DO-204AH) glass enclosure, the 'TR' suffix indicates tape and reel packaging.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Hermetically sealed glass package construction for environmental protection
- Minimal capacitance characteristics suitable for high-frequency applications
- Inherently radiation hard design
Applications
- Voltage reference circuits requiring stable DC levels
- Overvoltage protection networks
- Precision clipping and clamping applications
Procurement Notes
Verify that the specific ordering suffix matches the required tolerance and packaging configuration. Confirm whether the application requires the standard metallurgical bond or the enhanced reliability provided by the internal metallurgical bond option associated with military qualifications. Ensure the procurement specification aligns with the commercial grade RoHS status if applicable.
Selection Notes
Select this component when a 9.1 V regulation point is required with tight voltage tolerances. The B suffix guarantees a 5% voltage tolerance, distinguishing it from standard commercial variants. Consider the thermal resistance and power derating curves if the operating environment exceeds standard ambient conditions or if PCB mounting affects heat dissipation.
Part Context
This part belongs to the 1N5518 through 1N5546 series of 0.5 W axial-leaded glass Zener Voltage Regulators. The series offers a wide selection of voltages from 3.3 V to 33 V with various tolerance options. The 1N5529B variant specifically targets the 9.1 V breakdown region with guaranteed parameter limits for voltage, impedance, and leakage.
Replacement Considerations
Equivalent parts include JAN1N5529B-1 and JANTXV1N5529B-1, which offer military qualification levels. These substitutes maintain the same electrical specifications but require the internal metallurgical bond option (-1 suffix) and provide higher reliability standards.
