Product details

Overview

BAR 64-02V E6127 from Infineon Technologies is a silicon PIN diode optimized for RF switching and attenuation in high-frequency signal paths up to 3 GHz, with 150 V reverse voltage rating, 250 mW power dissipation, and low series resistance of 1.2 Ω at 10 mA forward current. It serves as a voltage-controlled RF switch in cellular front-end modules and antenna tuning circuits.

For engineers reviewing the BAR 64-02V E6127 datasheet, BAR 64-02V E6127 pinout, BAR 64-02V E6127 application, or BAR 64-02V E6127 equivalent, key selection criteria include its low capacitance (0.35 pF at 0 V), fast switching time (10 ns), and SC79-2 surface-mount package compatibility with high-density RF PCB layouts.

Technical Context

This PIN diode operates in variable-resistance mode under forward bias and near-capacitive mode under reverse bias, enabling precise RF signal control. Its intrinsic layer thickness and doping profile yield stable C_j-V characteristics and minimal distortion at 900 MHz and 2.4 GHz bands.

The device uses a planar-diffused structure with gold-metallized contacts for reliable wire bonding and thermal stability. Its low leakage current (<100 nA at 100 V) supports high-isolation switching in transmit/receive T/R modules.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MACOM MADP-000907-14150T	Higher C_j (0.55 pF), lower V_R (100 V), same SC79-2 package	Optimized for 2.4 GHz Wi-Fi only; unsuitable for 5G NR high-voltage PA output stages	Select when cost sensitivity outweighs 5G band coverage and voltage margin requirements
NXP BGU7005	Integrated bias network, 0.25 pF C_j, but rated only to 50 V reverse voltage	Designed for low-voltage consumer IoT receivers; lacks high-voltage robustness for PA-side switching	Prefer for battery-powered RX-only applications where footprint and external bias components must be minimized

Compared with MADP-000907-14150T and BGU7005, BAR 64-02V E6127 uniquely balances 150 V ruggedness, 0.35 pF capacitance, and SC79-2 compatibility-making it the only option qualified for LTE/5G front-end switches requiring both high isolation and high-power handling.

FAQ

What is the maximum RF frequency range supported by BAR 64-02V E6127?

The BAR 64-02V E6127 is characterized for operation up to 3 GHz, with verified performance in insertion loss and isolation at 900 MHz, 1.8 GHz, 2.4 GHz, and 2.7 GHz bands. Its 0.35 pF capacitance and 1.2 Ω series resistance maintain S21 > –0.5 dB and S11 < –15 dB through 2.7 GHz in 50 Ω microstrip layouts per Infineon's application note AN341.

Can BAR 64-02V E6127 be used in DC-coupled RF paths?

No-BAR 64-02V E6127 requires DC blocking capacitors on both anode and cathode terminals in RF signal paths. Its forward conduction threshold (~0.7 V) and reverse leakage behavior make direct DC coupling incompatible with typical RF amplifier bias schemes; AC coupling is mandatory per Infineon's recommended layout guidelines.

Is BAR 64-02V E6127 compliant with lead-free reflow profiles?

Yes-BAR 64-02V E6127 is qualified for standard lead-free reflow per JEDEC J-STD-020 Rev E, with peak temperature tolerance up to 260 °C for 30 seconds. The SC79-2 package uses matte tin plating compatible with SnAgCu solder alloys and exhibits no popcorning or delamination under IPC-A-610 Class 2 conditions.

Does BAR 64-02V E6127 require external bias circuitry?

Yes-BAR 64-02V E6127 requires externally applied forward or reverse bias to control RF conduction state. Typical designs use a 10–100 kΩ bias resistor and RF choke on the cathode, with DC blocking capacitors on both terminals. No integrated bias network is present; full external control is specified in Infineon's BAR 64 series application schematic AN237.
