Product details
Overview
BGF110E6327XT from Infineon Technologies is a wafer-level packaged ESD protection device specifically designed for SD card interface lines, featuring integrated 40 Ω series resistors on nine data/command lines, 50 kΩ pull-up/down resistors on control lines, and ESD robustness up to ±15 kV contact discharge per IEC61000-4-2. It delivers low line capacitance (11.5–13.5 pF at 0–5 V bias), <−35 dB RF attenuation above 10 MHz, and <−70 dB analog crosstalk at 100 MHz.
For engineers reviewing the BGF110E6327XT datasheet, BGF110E6327XT pinout, BGF110E6327XT application, or BGF110E6327XT equivalent, this component supports high-speed SD 2.0/3.0 digital interfaces requiring simultaneous ESD hardening, RF filtering, and signal integrity preservation without compromising timing margins.
Technical Context
The BGF110 integrates discrete ESD diodes with precision thin-film resistors in a monolithic WLP-24-2 structure, enabling co-located protection and impedance matching directly at the SD connector. Its internal topology separates external I/Os (A4–E5) - rated for ±15 kV contact discharge - from internal I/Os (A1–E2, C3) - rated for ±2 kV - using distinct resistor networks and diode clamping paths.
Line capacitance remains stable across 0–5 V bias (11.5–13.5 pF), and RF suppression is achieved via distributed RC filtering: each protected line includes a 40 Ω series resistor (R1–R9) plus parallel 50 kΩ bias resistors (R11–R14) and a 15 kΩ pull-down (R15), with R21 (470 kΩ) isolating the SDWP+CD line.
Key Specifications

| Wafer-level green packaging | RoHS-compliant SnAgCu balls and no mold compound enable ultra-thin (<0.4 mm) mounting for slim card readers |
| EMI/RF suppression | −35 dB attenuation at 100 MHz and −70 dB crosstalk reduce conducted/radiated emissions to meet CISPR 22 Class B |
| Dual ESD rating zones | Separate ±15 kV (external) and ±2 kV (internal) protection paths prevent overstress of bias circuitry during connector handling |
Applications
| SD Card Slot Protection | Portable Media Player Interface |
|---|---|
Use Scenario: SD card insertion/removal in consumer handheld devices subject to frequent human-handling ESD events. IC Role / Device Role / Timing Role: Primary ESD clamp and RC filter on all SD bus lines (DATA0–3, CMD, CLK, CD, WP), placed within 3 mm of the card edge connector. Use Value: Eliminates need for discrete 0402 TVS diodes and bias resistors, reducing layout area by >60% while maintaining 50 MHz SD timing margins. | Use Scenario: High-density PCB in MP3 players where SD interface shares space with audio codec and RF section. IC Role / Device Role / Timing Role: Simultaneous ESD hardening and RF noise suppression on SD lines to prevent coupling into sensitive analog audio paths. Use Value: −70 dB crosstalk at 100 MHz prevents audible artifacts during SD file transfers; 40 Ω series resistance damps ringing without violating SD 2.0 setup/hold requirements. |
| Industrial SD Host Controller | Automotive Infotainment SD Slot |

IC Role / Device Role / Timing Role: Temperature-stable ESD protection with minimal capacitance drift, ensuring reliable SD initialization across full industrial temperature range. Use Value: Line capacitance variation <0.5 pF from −40 °C to +85 °C avoids marginal timing failures during cold-start SD enumeration. | Use Scenario: SD card slot in automotive head unit exposed to ISO 10605 ESD pulses and wide thermal cycling. IC Role / Device Role / Timing Role: Dual-zone ESD protection: ±15 kV on exposed card lines, ±2 kV on internal WP/CD control nets tied to MCU GPIOs. Use Value: Prevents latch-up or damage to host MCU pins during card hot-swap while meeting AEC-Q200 stress test requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SD card interface ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1002-01WTG | No integrated resistors; requires external 40 Ω series and 50 kΩ bias components; 12 pF capacitance | Higher BOM count and layout area; less optimal for space-constrained SD slots | Choose when existing design uses discrete resistor networks and only ESD diode replacement is needed |
| ESD7L5.0ST5G | Single-line 5 V TVS only; no filtering resistors or multi-line integration; 30 pF capacitance | Cannot replace BGF110's full SD bus protection; limited to point-of-use clamping on individual lines | Use only for retrofitting legacy designs lacking integrated RC networks and accepting higher capacitance penalty |
Compared with SP1002-01WTG and ESD7L5.0ST5G, the BGF110E6327XT uniquely combines 10-line ESD protection, matched series resistance, and bias networks in one WLP package-reducing component count by 12× and preserving SD timing integrity where discrete solutions risk margin loss.

FAQ
What is the maximum recommended trace length between BGF110E6327XT and the SD card connector?
Trace length should not exceed 3 mm from each BGF110 ball to its corresponding SD connector pin. Longer traces degrade ESD current shunting efficiency and increase inductance, reducing the effectiveness of the 40 Ω series resistors in damping fast transients. Layout guidelines in the datasheet specify tight routing to maintain <0.3 nH inductance per line.
Does BGF110E6327XT support SDIO or only standard SD/MMC protocols?
Yes, it supports both SDIO and standard SD/MMC protocols. Its 40 Ω series resistance and 11.5–13.5 pF capacitance are optimized for 0–50 MHz signaling, covering SDIO's typical 25–48 MHz clock rates and SD 2.0's 25 MHz default mode. The dual-zone ESD rating also accommodates SDIO's additional function pins.
Can BGF110E6327XT be used with UHS-I SD cards?
No, BGF110E6327XT is not suitable for UHS-I (Ultra High Speed Mode I) due to its 13.5 pF max line capacitance and lack of impedance-controlled routing support. UHS-I requires <8 pF capacitance and controlled 50 Ω traces; this device is validated only for SD 2.0/3.0 default and high-speed modes up to 50 MHz.
How is thermal dissipation managed during 15 kV ESD events?
During a 15 kV contact discharge, peak power is absorbed by the integrated silicon diodes and dissipated through the 24 solder balls into the PCB ground plane. The datasheet specifies 1131 mA absolute maximum current for 24 hours - but ESD pulses are sub-100 ns, so thermal mass of the copper pads and internal die structure safely handles transient energy without degradation.
