Overview
The Microchip Technology 1N5532A is a single Zener diode with a nominal voltage of 12 V and a maximum power dissipation of 500 mW. It features a tolerance of ±5% and operates within a temperature range of -65°C to +175°C. The device utilizes a DO-35 axial through-hole package. Key electrical parameters include a maximum Zener impedance (Zzt) of 90 Ohms, a reverse leakage current of 50 nA at 10.8 V, and a forward voltage of 1.1 V at 200 mA.
Feature Summary
- Provides stable voltage regulation via avalanche breakdown characteristics
- Features low reverse leakage current for improved circuit efficiency
- Utilizes metallurgically bonded construction for enhanced reliability
Applications
- Voltage reference circuits in precision measurement systems
- Overvoltage protection in sensitive electronic components
- Clamping applications in signal processing paths
Procurement Notes
Verify the specific suffix designation against official Microchip documentation to confirm exact tolerance and qualification levels. Ensure compatibility with MIL-PRF-19500/437 requirements if military-grade performance is mandated. Confirm RoHS status as non-compliant for legacy applications requiring this specific component variant.
Selection Notes
Select the 1N5532A when a 12 V Zener voltage with 500 mW power handling is required in an axial leaded package. Consider the ±5% tolerance and high operating temperature range for harsh environments. Evaluate the 90 Ohm impedance for dynamic regulation needs in the target application circuit.
Part Context
This component belongs to the 1N5532 series of low voltage avalanche Zener diodes manufactured by Microchip Technology. It shares functional similarities with other variants in the 1N55xx family but is distinguished by its specific voltage rating and through-hole packaging configuration suitable for general-purpose discrete semiconductor applications.
Replacement Considerations
JAN1N5532A is a parameter-equivalent alternative from Microchip Technology offering similar specifications.
