MA4P4301F-1091T

RF Diode Overview

The MA4P4301F-1091T is a high power PIN diode from the MACOM MA4P MELF & HIPAX series, designed for switch and attenuator applications requiring high power handling and low distortion. It features a fully passivated PIN diode chip with a thick I-region and long carrier lifetime while maintaining low series resistance and capacitance values. The device is enclosed in a rugged ceramic package (MELF SMQ) and is full face bonded to metal pins on both the anode and cathode, resulting in low loss and low thermal resistance due to symmetrical thermal paths. Key electrical specifications include a maximum reverse voltage of 100 VDC, a maximum total capacitance of 2.0 pF, a maximum series resistance of 1.0 Ω at 100 mA forward current, and a minimum parallel resistance of 50 kΩ at 100 V reverse bias.

RF Diode Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. The 'F' designation indicates a MELF surface mount package, while the '1091T' suffix specifies tape and reel quantities. Ensure compatibility with standard reflow and vapor phase soldering processes as tin-plated surfaces are utilized. Cross-reference the exact part number with the manufacturer's latest datasheet to confirm availability and any potential updates to specifications or environmental compliance status.

RF Diode Selection Notes

Select this component when designing circuits that require high power handling combined with low distortion performance. The 100 V reverse voltage rating and 1.0 Ω series resistance make it suitable for various switching and attenuation tasks. Consider the MELF package for automated assembly processes. Evaluate the thermal management requirements based on the specified thermal resistance values under different heatsink conditions. Ensure the application frequency range aligns with the diode's capacitance and carrier lifetime characteristics for optimal signal integrity.
