HMPP-3890-TR1

RF Diode Overview

The Broadcom HMPP-3890-TR1 is a single PIN diode switch in the MiniPak 1412 surface mount package. It features a maximum breakdown voltage of 100 V, a maximum series resistance of 2.5 Ω at 5 mA forward current, and a maximum total capacitance of 0.30 pF at 5 V reverse bias. The device operates within a junction temperature range of -65°C to +150°C and supports a peak inverse voltage of 100 V. Typical parameters include a carrier lifetime of 200 ns and a typical total capacitance of 0.20 pF at 5 V.

RF Diode Feature Summary

• Ultra-miniature leadless MiniPak 1412 ceramic-based package designed for reduced parasitics and lower thermal resistance compared to conventional leaded diodes.
• Optimized epitaxial construction providing low resistance at low currents and low junction capacitance for high-frequency switching applications.
• Manufacturing techniques ensure matched diodes when packaged in pairs, guaranteeing consistent performance across devices.

RF Diode Applications

• RF and microwave switching networks
• Cellular communication systems (e.g., 930 MHz)
• RFID applications (e.g., 1.8 GHz PCS, 2.45 GHz)

RF Diode Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm packaging quantity and reel specifications. Confirm that the component matches the MiniPak 1412 footprint dimensions and pin configuration required by the design. Ensure static discharge precautions are observed during handling due to ESD sensitivity.

RF Diode Selection Notes

Select this component for designs requiring low parasitic inductance and capacitance in a compact surface-mount form factor. Consider the 100 V breakdown rating and 2.5 Ω series resistance limits when designing bias circuits. Evaluate the trade-off between switching speed and isolation based on the 200 ns carrier lifetime specification for the target frequency band.
