Product details
Overview
EMIF02-01OABRY from STMicroelectronics is an AEC-Q101-qualified, automotive-grade integrated low-pass EMI filter with 15 kV ISO 10605 ESD protection, designed specifically for BroadR-Reach™ Ethernet interfaces. It provides differential return loss of –20 dB at 60 MHz, 1% component matching between lines, and operates across –40 °C to +125 °C in a wettable-flank QFN (3.0 × 3.0 mm, 6-pin).
For engineers reviewing the EMIF02-01OABRY datasheet, EMIF02-01OABRY pinout, EMIF02-01OABRY application, or EMIF02-01OABRY equivalent, this device serves as a signal-integrity-preserving front-end filter for 100BASE-T1 automotive Ethernet PHY interfaces requiring robust EMC immunity and high-temperature reliability.
Technical Context
The EMIF02-01OABRY integrates matched RC low-pass filtering and bidirectional ESD protection diodes into a single monolithic structure optimized for differential BroadR-Reach™ signaling. Its internal topology supports symmetric line-to-line (pins 1–3) and line-to-transceiver (pins 4–6) paths with tightly controlled impedance and timing alignment.
It delivers defined attenuation (Sdd21 ≤ –50 dB at 100 MHz), differential return loss compliance (Sdd11/Sdd22 ≤ –20 dB from 10–60 MHz), and transient suppression per ISO 7637-3 Pulse 3a (–150 V) and 3b (+100 V), all validated across full automotive junction temperature range.

Pinout & Package
EMIF02-01OABRY uses a 6-terminal wettable-flank QFN package (3.0 × 3.0 mm, 0.5 mm pitch) with exposed thermal pad. Pin numbering follows standard QFN orientation (pin 1 marked by dot, counterclockwise).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Differential input line A (external side) | Connects to BroadR-Reach™ cable-side differential pair; carries ESD stress and RF noise |
| Pin 2 | Ground (exposed thermal pad) | Primary thermal and EMI reference plane; must be soldered to PCB ground pour |
| Pin 3 | Differential input line B (external side) | Complementary external line; matched to pin 1 for <1% imbalance over temp |
| Pin 4 | Differential output line A (transceiver side) | Connects to PHY IC differential receiver; filtered and protected signal path |
| Pin 5 | Ground (exposed thermal pad) | Shared ground terminal with pin 2; ensures low-inductance return path |
| Pin 6 | Differential output line B (transceiver side) | Complementary transceiver-side line; maintains symmetry with pin 4 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar EMI-filtered BroadR-Reach™ interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| EMIF02-02OABRY | Same footprint and function but includes solder-filled dimples for enhanced thermal dissipation | Preferred for extended high-temp operation (>110 °C ambient) or higher-power PHYs | Select when thermal margin is constrained and board-level airflow is limited |
| TPD2E001DRYR | Discrete dual-channel ESD array (no integrated filtering); RDC = 0.8 Ω; no S-parameter compliance data | Requires external RC filter design; not pre-validated for BroadR-Reach™ return loss | Use only if custom filter tuning is required and AEC-Q101 requalification is feasible |
Compared with EMIF02-02OABRY, the EMIF02-01OABRY offers identical EMC performance with lower thermal mass; versus TPD2E001DRYR, it eliminates layout-dependent filter design effort but trades off flexibility for turnkey BroadR-Reach™ compliance.

FAQ
What is the maximum recommended trace length between EMIF02-01OABRY and the PHY IC?
ST recommends keeping the trace length from pins 4/6 to the PHY differential inputs ≤ 8 mm with controlled 100 Ω differential impedance. Longer traces increase stub effects and degrade Sdd21 attenuation above 50 MHz, risking failure to meet BroadR-Reach™ mask requirements.
Does EMIF02-01OABRY require external biasing or power supply?
No. The EMIF02-01OABRY is a fully passive device containing only RC networks and ESD protection diodes. It draws zero quiescent current and requires no external voltage rails, pull-ups, or configuration pins - it operates transparently in-circuit.
Can EMIF02-01OABRY be used with 1000BASE-T1 or multi-gigabit automotive Ethernet?
No. Its S-parameter profile is validated only up to 100 MHz and optimized for 100BASE-T1 (100 Mbps). At 1000BASE-T1 frequencies (>400 MHz), Sdd21 attenuation drops below –15 dB, violating spectral mask and jitter budget requirements.
How does the wettable flank feature impact reflow soldering yield?
The wettable flanks enable reliable side-vision AOI detection of solder fillet formation, improving first-pass yield by >99.8% in high-volume automotive SMT lines. ST's recommended reflow profile (peak 240–245 °C, ramp rate ≤3 °C/s) ensures full wetting without voiding or pad lifting.
