HMPP-3895-TR2

RF Diode Overview

The HMPP-3895-TR2 is a surface mount RF PIN switch diode from the Broadcom HMPP-389x series, housed in a MiniPak 1412 package. It features two parallel-connected diodes within a single leadless ceramic component. Key electrical specifications include a minimum breakdown voltage of 100 V and a maximum total capacitance of 0.30 pF at 1 MHz. The device exhibits a maximum series resistance of 2.5 Ω at 5 mA forward current. It supports a peak inverse voltage of 100 V and a forward current pulse of 1 A. The junction temperature rating reaches 150°C with a thermal resistance of 150 °C/W.

RF Diode Feature Summary

• Dual parallel diode configuration provides matched performance for consistent switching characteristics.
• Optimized epitaxial construction ensures low resistance at low bias currents and low junction capacitance.
• Enhanced thermal conductivity allows for higher power dissipation compared to conventional leaded packages.

RF Diode Applications

• RF and microwave switching networks
• High isolation SPDT switches using dual bias
• Battery-operated switching applications requiring low drive current

RF Diode Procurement Notes

Verify the specific ordering suffix TR2 indicates a 10,000-unit quantity on a 13-inch reel. Confirm that the HMPP-3895 variant matches the required parallel diode configuration for the circuit design. Ensure compatibility with standard surface mount assembly processes and reflow temperatures not exceeding 260°C.

RF Diode Selection Notes

Select this component when a parallel diode arrangement is required within an ultra-low profile surface mount package. The HMPP-3895 offers lower series resistance than bulk diodes while maintaining low capacitance suitable for frequencies up to several gigahertz. Consider the MiniPak 1412 footprint constraints and the need for precise PCB pad layouts to minimize parasitic effects.

RF Diode Part Context

This part belongs to the HMPP-389x series of surface mount RF PIN switch diodes manufactured by Broadcom (formerly Avago Technologies). The series utilizes advanced semiconductor techniques combined with leadless packaging technology to deliver high-performance switching solutions in a compact form factor suitable for modern electronic designs.

RF Diode Replacement Considerations

HMPP-3895-TR1 serves as a direct replacement with identical electrical characteristics but differs in packaging quantity, containing 3,000 units per 7-inch reel instead of 10,000 units.
