GC2532-150A

Overview

The GC2532-150A is a step recovery diode from the GC2500 series, manufactured by Microsemi (Microchip Technology). It is an epitaxial silicon varactor designed for high output power and efficiency in harmonic generator applications. The device features a minimum breakdown voltage of 30V at 10μA leakage current and a junction capacitance range of 0.6 to 0.8 pF measured at -6V. Key electrical parameters include a typical transition time of 100 ps and a maximum series resistance of 0.5 Ω at 25 mA. The component supports operating temperatures from -55°C to +125°C and utilizes a Style 150 package.

Feature Summary

• Provides high output power and efficiency in harmonic generation applications
• Features low transition time (snap time) for precise pulse shaping
• Utilizes silicon dioxide passivation for reliability and low leakage currents
• RoHS compliant with gold finish

Applications

• Harmonic generators for multiplication orders X2 through X20
• Local oscillators and voltage controlled oscillators
• Frequency synthesizers and up converters
• Comb generators for broad frequency spectrum generation
• High speed pulse shaping circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm mechanical package compatibility. Ensure ESD handling precautions are strictly followed during storage and assembly due to component sensitivity. Confirm that the Style 150 package meets the thermal and spatial requirements of the target design before finalizing procurement.

Selection Notes

Select this component based on the required breakdown voltage and junction capacitance values. The GC2532 variant offers a 30V rating with 0.6-0.8 pF capacitance. Evaluate the series resistance and transition time specifications against the circuit's frequency and power requirements. Consider the operating temperature range and thermal resistance when designing the heat dissipation strategy for the application.

Part Context

The GC2532-150A belongs to the GC2500 series of step recovery diodes produced by Microsemi, now part of Microchip Technology. This series comprises various models differentiated by breakdown voltage and capacitance ranges. The devices are engineered for microwave power generation and signal processing applications requiring fast switching characteristics and high reproducibility.

Replacement Considerations

Direct substitutes within the GC2500 series include GC2531 and GC2533, which share the same 30V breakdown voltage but offer different junction capacitance ranges. Verify that any replacement maintains the required transition time and series resistance specifications for the specific harmonic generation or pulse shaping application.
