Product details

Overview

BAR 64-02LRH E6433 from Infineon Technologies is a high-voltage RF PIN diode optimized for switching and attenuation in UHF/VHF front-end modules, featuring 150 V peak inverse voltage, 250 mW power dissipation, and low series resistance of 1.2 Ω at 10 mA DC bias - deployed in automotive keyless entry transmitters and ISM-band remote controls.

For engineers reviewing the BAR 64-02LRH E6433 datasheet, BAR 64-02LRH E6433 pinout, BAR 64-02LRH E6433 application, or BAR 64-02LRH E6433 equivalent, key selection criteria include reverse breakdown voltage, forward resistance under RF signal conditions, thermal resistance in TSLP-2 package, and switching speed for burst-mode RF envelope control.

Technical Context

This PIN diode operates as a voltage-controlled RF resistor: its intrinsic region enables linearized conductance modulation under forward bias, while sustaining 150 V reverse standoff. It exhibits 0.7 pF capacitance at 0 V and <1 ns carrier lifetime - critical for sub-1 GHz switching fidelity and minimal harmonic generation in transmit/receive antenna switching paths.

The TSLP-2 surface-mount package provides 180 K/W junction-to-ambient thermal resistance and supports reflow-compatible assembly. Its symmetrical two-terminal structure eliminates polarity-dependent mounting constraints, simplifying PCB layout in compact RF front-ends.

Equivalent & Alternatives

The following parts are listed as comparable options for similar RF PIN diode switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NXP BAP64-03,115	100 V PIV, 0.5 pF C_j, 1.5 Ω R_S, SOT-23 package	Limited to ≤315 MHz systems due to lower breakdown voltage; higher capacitance degrades 868 MHz isolation	Select when cost-sensitive 315 MHz designs prioritize capacitance over voltage margin
ON Semiconductor MMBD701LT1G	75 V PIV, 1.0 pF C_j, 2.0 Ω R_S, SOT-23 package	Not suitable for automotive 12 V rail environments; higher R_S increases insertion loss above 400 MHz	Use only in low-voltage consumer remotes where thermal derating is not required

Compared with BAP64-03 and MMBD701LT1G, BAR 64-02LRH E6433 delivers superior voltage headroom and lower RF loss in 433/868 MHz industrial and automotive transceivers - making it the preferred choice where system-level reliability under electrical stress is non-negotiable.

FAQ

What is the maximum RF input power BAR 64-02LRH E6433 can handle in series-switch configuration?

At 433 MHz with 10 mA forward bias, BAR 64-02LRH E6433 supports up to +23 dBm continuous wave input before exceeding its 250 mW power dissipation limit. Derating to 180 mW is recommended for 85°C ambient operation to ensure 10-year reliability in sealed enclosures.

Does BAR 64-02LRH E6433 require DC blocking capacitors in shunt-switch topology?

Yes - a minimum 100 pF DC-blocking capacitor must be placed in series with the anode terminal to prevent forward-bias current from shorting the RF signal path to ground. This preserves RF impedance integrity while enabling independent DC bias control.

Can BAR 64-02LRH E6433 be used in 2.4 GHz Bluetooth LE applications?

No - its 0.7 pF junction capacitance and 1.2 Ω series resistance yield >1.2 dB insertion loss and <20 dB isolation at 2.4 GHz. It is optimized for ≤1 GHz operation; for 2.4 GHz, Infineon's BAP70-03 (0.35 pF, 0.8 Ω) is specified.

Is the TSLP-2 package compatible with standard reflow profiles for lead-free soldering?

Yes - BAR 64-02LRH E6433 meets JEDEC J-STD-020D moisture sensitivity level 1 and is qualified for peak reflow temperatures up to 260°C. The thermal pad design supports full-solder joint formation without voiding when using recommended stencil aperture and paste volume.
