Overview
The Microchip Technology 1N5524B/TR is a low voltage avalanche Zener diode with a nominal breakdown voltage of 5.6 V at a test current of 3.0 mA. It operates within the 1N5518 through 1N5546 series, offering a maximum power dissipation of 0.5 W and a voltage tolerance of ±5%. The device features a hermetically sealed axial-lead glass DO-35 (DO-204AH) package and supports an operating temperature range from -65°C to +175°C.
Feature Summary
- Hermetically sealed axial-lead glass construction for environmental stability
- Qualified per MIL-PRF-19500/437 standards for JAN, JANTX, and JANTXV reliability levels
- Inherently radiation hard design suitable for harsh environments
- Minimal capacitance characteristics for high-frequency applications
Applications
- Voltage regulation over broad operating current and temperature ranges
- Reference voltage sources in precision electronic circuits
- Protection against electrostatic discharge (ESD)
- Overvoltage protection in aerospace and defense systems
Procurement Notes
Verify that the specific ordering suffix matches the required voltage tolerance and metallurgical bond configuration. Confirm whether RoHS compliance is necessary, as it applies only to commercial grade versions. Ensure the TR suffix is correctly applied for tape and reel packaging requirements. Cross-reference the part number with the manufacturer's latest datasheet to confirm availability and lead times.
Selection Notes
Select this component when a stable 5.6 V reference is required in a ruggedized environment. The B suffix guarantees a tighter ±5% voltage tolerance compared to standard JEDEC types. Consider the DO-35 package dimensions for board layout constraints. Evaluate thermal derating curves if operating near the maximum power dissipation limit.
Part Context
This device belongs to the 1N5518 thru 1N5546 series of 0.5 watt axial-leaded glass Zener Voltage Regulators. The series provides a selection of voltages ranging from 3.3 to 33 volts. The 1N5524 variant specifically targets the 5.6 V breakdown region within this comprehensive lineup.
Replacement Considerations
Equivalent parts include the 1N5524D for tighter tolerance or 1N5524A for looser tolerance. Verify compatibility with MIL-PRF-19500/437 specifications if military qualification is required.
