HMPP-389T-TR2

RF Diode Overview

The HMPP-389T-TR2 is a surface mount RF PIN switch diode from the Broadcom Limited HMPP-389x series, housed in a MiniPak 1412 leadless package. It functions as a low inductance wide band shunt switch optimized for applications up to 6 GHz. The device features a single diode configuration with a maximum breakdown voltage of 100 V and a maximum total capacitance of 0.30 pF at 5 V reverse bias. Its typical series resistance is 3.8 Ω at 1 mA forward current, with a carrier lifetime of 200 ns. The component supports a peak inverse voltage of 100 V and operates within a junction temperature range of -65°C to +150°C.

RF Diode Applications

• RF and microwave switching networks
• High isolation SPDT switches
• Wideband shunt switching applications

RF Diode Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm container type and quantity. The TR2 suffix indicates a 13-inch reel containing 10,000 devices. Ensure compatibility with standard surface mount assembly processes, noting that the maximum reflow temperature should not exceed 260°C. Confirm availability status directly with authorized distributors as supply conditions may vary.

RF Diode Selection Notes

Select this component when designing circuits requiring a shunt switch topology with minimal parasitic inductance. The MiniPak 1412 package is preferred over SOT-23 or SC-70 packages for frequencies exceeding conventional limits due to lower package parasitics. Consider the 100 V peak inverse voltage rating for robustness in high-voltage reverse bias scenarios. Evaluate the 0.30 pF maximum capacitance to ensure it meets the isolation requirements of the target frequency band.

RF Diode Part Context

The HMPP-389T-TR2 belongs to the HMPP-389x series of miniaturized PIN diodes manufactured by Broadcom Limited (formerly Avago Technologies). This series utilizes advanced semiconductor processing combined with leadless ceramic-based packaging technology. The product line includes single, anti-parallel, parallel, and shunt switch configurations, all designed to offer matched performance and high reliability through adjacent wafer site packaging.

RF Diode Replacement Considerations

The HSMP-389T is a direct functional equivalent utilizing an SC-70 package. While electrically similar, the HSMP-389T exhibits higher parasitic inductance due to its leaded construction. Designers replacing the HMPP-389T with the HSMP-389T must account for potential performance degradation at frequencies approaching 6 GHz.
