Infineon Technologies BA595E6327HTSA1

Overview

BA595E6327HTSA1 from Infineon Technologies is a silicon PIN diode optimized as a current-controlled RF resistor for antenna switching and RF attenuation in TV-satellite tuners. It operates from 1 MHz to 2 GHz, exhibits ≤0.4 pF diode capacitance at VR = 0 V / f = 100 MHz, 22 Ω forward resistance at IF = 1.5 mA / f = 100 MHz, and supports 50 V reverse voltage with AEC-Q101 qualification.

For engineers reviewing the BA595E6327HTSA1 datasheet, BA595E6327HTSA1 pinout, BA595E6327HTSA1 application, or BA595E6327HTSA1 equivalent, key selection criteria include its low harmonic distortion, 130 µm I-region width enabling fast switching (τrr typ. 1600 ns), and SCD80 package thermal resistance of ≤95 K/W junction-to-soldering-point.

Technical Context

This PIN diode functions as a voltage-variable RF impedance element: forward bias controls series resistance (rf), while reverse bias sets shunt capacitance (CT) and isolation. Its 130 µm intrinsic region enables nanosecond-scale carrier lifetime (τrr typ. 1600 ns), critical for high-speed antenna switching in satellite tuner front-ends.

Designed for DC-biased RF signal paths, it delivers ≤0.26 pF capacitance at VR = 0 V / 100 MHz and ≥50 kΩ reverse parallel resistance at VR = 1 V / 100 MHz - parameters directly governing insertion loss, isolation, and harmonic suppression in 1–2 GHz band applications.

Key Specifications

Pinout & Package

FAQ

What is the maximum continuous forward current for BA595E6327HTSA1?

The absolute maximum DC forward current is 50 mA at TA = 25°C. Derating is required above 25°C ambient: at 85°C, maximum IF drops to ~30 mA per thermal resistance data and permissible pulse load curves in the datasheet. Pulse operation allows higher peak currents depending on duty cycle and pulse width.

Does BA595E6327HTSA1 require external bias circuitry?

Yes - it requires a DC bias network to set forward or reverse conduction state. Typical implementation uses a series resistor and RF choke to isolate DC bias from RF signal path while maintaining low insertion loss. No integrated bias controller is present; external control is mandatory for RF switching function.

Is BA595E6327HTSA1 compatible with lead-free reflow soldering?

Yes - it is Pb-free and RoHS compliant, qualified for standard lead-free reflow profiles (J-STD-020, peak temperature ≤260°C). The SCD80 package withstands three reflow cycles without degradation, and moisture sensitivity level (MSL) is rated at MSL 1 - unlimited floor life under dry storage.

How does BA595E6327HTSA1 perform at elevated temperatures?

It maintains full functionality from –55°C to +125°C operating range. At +125°C, forward resistance increases by ~25%, CT decreases by ~8%, and τrr shortens by ~30% versus 25°C - all within specified limits. Junction temperature must remain ≤150°C, enforced via RthJS ≤95 K/W and appropriate PCB copper area.
