Product details
Overview
BAR 88-07LRH E6327 from Infineon Technologies is a silicon PIN diode optimized for low-current antenna switching in handheld RF front-ends. It delivers 1.5 Ω forward resistance at 1 mA, 0.28 pF capacitance at 0 V/1 GHz, and 11 dB isolation at 1.8 GHz - enabling high-efficiency RF path selection in 4G/LTE mobile transceivers.
For engineers reviewing the BAR 88-07LRH E6327 datasheet, BAR 88-07LRH E6327 pinout, BAR 88-07LRH E6327 application, or BAR 88-07LRH E6327 equivalent, key selection criteria include RF insertion loss (0.06 dB @ 1.8 GHz, 10 mA), reverse isolation performance across 0.9–2.45 GHz, and thermal resistance (≤65 K/W) for compact PCB layouts.
Technical Context
This PIN diode operates as a voltage-controlled RF switch in series configuration with 50 Ω impedance matching. Its I-region width of 13 µm enables fast carrier lifetime (500 ns typ.) and low distortion under small-signal RF conditions up to 2.45 GHz.
Designed for zero-bias or low-forward-current control, it achieves sub-0.3 pF capacitance at 1 GHz and maintains ≥1.5 kΩ reverse parallel resistance at 1.8 GHz - critical for minimizing signal leakage and maintaining antenna port isolation in multi-band handset architectures.

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 |
|---|---|---|---|
| SKY13370-374LF | Higher IF rating (200 mA), 0.22 pF CT @ 1 GHz, integrated matching network | Targeted for higher-power PA output switching, not low-current antenna diversity | Select when >50 mA forward current or integrated 50 Ω matching required |
| BAT54CW,115 | Schottky diode, VF = 0.33 V @ 10 mA, CT = 10 pF @ 1 MHz - no RF-optimized I-layer | General-purpose clamping or ESD protection, not RF path switching | Avoid for >500 MHz applications due to excessive capacitance and poor isolation |
Compared with SKY13370-374LF and BAT54CW,115, BAR 88-07LRH E6327 uniquely balances ultra-low capacitance, sub-ohm RF resistance, and MSL1 reflow compatibility - making it the only validated choice for space-constrained, low-current antenna switching in certified mobile platforms.

FAQ
What is the maximum RF frequency supported by BAR 88-07LRH E6327?
BAR 88-07LRH E6327 is characterized up to 2.45 GHz, with verified isolation (9 dB) and insertion loss (0.06 dB) at 1.8 GHz. Its 0.25 pF capacitance at 1.8 GHz and 1.5 kΩ reverse parallel resistance confirm functional operation through the entire 2.4 GHz ISM band, though datasheet validation stops at 2.45 GHz.
Can BAR 88-07LRH E6327 be used in shunt configuration?
Yes - the device supports both series and shunt configurations. In shunt mode, cathode connects to RF line and anode to RF ground; isolation improves at lower frequencies but insertion loss increases above 1 GHz due to parasitic inductance of the ground path.
Does BAR 88-07LRH E6327 require external DC blocking capacitors?
Yes - because it lacks internal DC isolation, external 100 pF NP0 capacitors are required on both anode and cathode terminals when used in AC-coupled RF paths to prevent bias voltage from affecting adjacent circuitry or violating impedance matching.
What is the thermal derating behavior above 25°C ambient?
At 85°C board temperature, forward current must be limited to ~60 mA to maintain junction temperature ≤150°C. Derating follows the curve in datasheet Figure 5: IF drops linearly from 100 mA at 25°C to 0 mA at 150°C ambient, constrained by RthJS ≤65 K/W and Ptot = 250 mW.
