Product details
Overview
AFBR-395000RZ from Broadcom is a high-voltage galvanic insulation link for DC to 50 Mbaud data transmission, integrating optical transmitter and receiver at 650 nm wavelength, with 101.2 mm creepage/clearance distance, 50 kV peak transient voltage suppression per IEC 60644, and dual 3.3 V/5 V supply compatibility - used in smart grid onboard insulation and medium-voltage power distribution systems.
For engineers reviewing the AFBR-395000RZ datasheet, pinout, applications, or equivalent options, key selection criteria include verified 50 kV isolation rating, non-inverted DC-coupled CMOS/TTL I/O, 50 ns max propagation delay at 50 Mbaud, and RoHS-compliant UL-V0 housing with CTI 600.
Technical Context
The AFBR-395000RZ implements a fully integrated optocoupler architecture with separate transmitter (LED + driver) and receiver (integrated photodiode + TIA + output driver) sections, both featuring power-on reset (POR) active below 2.6 V and disabled above 2.8 V. It supports NRZ signaling without encoding, delivering non-inverted data transfer with <5 ns skew across units.
Its insulation system meets IEC-60747-5-5 certification and achieves 50 kV peak transient voltage (VIOTM_4inch), 35.2 kV effective isolation (VISO_4inch), and 12 kV working voltage (VIOWM_4inch) at pollution degree 2, enabled by 101.2 mm physical separation and UL-V0 housing with CTI 600.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Signaling Rate | DC to 50 Mbaud - supports full-rate NRZ communication without data encoding or clock recovery circuitry. |
| Transient Voltage Suppression | 50 kV peak (VIOTM_4inch) - enables use in Class III overvoltage environments per IEC 60664-1. |
| Creepage & Clearance | 101.2 mm - satisfies reinforced insulation requirements for 12 kV working voltage applications. |
| Propagation Delay | ≤50 ns at 50 Mbaud - ensures deterministic timing in high-speed feedback loops for inverters and drives. |
| Supply Voltage Range | 3.135–5.25 V for both Tx and Rx - allows direct interface with 3.3 V or 5 V logic without level-shifting. |
| Power-On Reset Threshold | Active ≤2.6 V, disabled ≥2.8 V - prevents metastable output during power ramp-up in industrial control systems. |
Pinout & Package
AFBR-395000RZ uses a through-hole, dual-inline package with 8 pins and 101.6 mm overall length (4-inch variant), UL-V0 thermoplastic housing, and 1.6 mm mounting hole diameter. Pin spacing follows standard DIP layout with 2.54 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Tx) | Transmitter VCC | Positive supply input for LED driver; accepts 3.3 V or 5 V with ≤100 mVpp noise. |
| 2 (Tx) | No function | Internally unused; must be connected to signal ground per datasheet recommendation. |
| 3 (Tx) | GND | Transmitter ground reference; separate from receiver ground for noise isolation. |
| 4 (Tx) | Data_in | CMOS/TTL-compatible electrical input; 0.8 V max low, 2 V min high threshold. |
| 5 (Rx) | No function | Internally unused; must be connected to signal ground per datasheet recommendation. |
| 6 (Rx) | Receiver VCC | Positive supply for receiver IC; independent biasing enables split-supply operation. |
| 7 (Rx) | GND | Receiver ground reference; isolated from Tx GND to maintain galvanic barrier integrity. |
| 8 (Rx) | Data_out | CMOS/TTL-compatible non-inverted output; 0.4 V max low, ≥2.5 V min high at load. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage galvanic insulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si866xBC-B-IS | Capacitive isolation; 5 kV RMS rating; 150 Mbps max; no optical components. | Lower isolation voltage (5 kV vs. 50 kV); unsuitable for Class III overvoltage locations. | Select only where 5 kV isolation suffices and EMI immunity is less critical than size/cost. |
| ISO7741FQDWRQ1 | Capacitive isolation; AEC-Q100 qualified; 5000 VRMS; 100 Mbps; automotive-grade. | Not certified to IEC 60644 or IEC 60747-5-5; lacks 50 kV transient rating and CTI 600 housing. | Prefer for automotive traction inverters; avoid for utility-grade smart grid or MV distribution where 50 kV VIOTM is mandated. |
Compared with Si866xBC-B-IS and ISO7741FQDWRQ1, the AFBR-395000RZ uniquely delivers 50 kV transient suppression, IEC 60747-5-5 certification, and UL-V0/CTI 600 housing - making it the only option qualified for reinforced insulation in 12 kV working voltage smart grid and medium-voltage distribution equipment.

FAQ
What is the maximum transient voltage rating for AFBR-395000RZ?
The AFBR-395000RZ has a maximum transient voltage rating of 50 kV peak (VIOTM_4inch) per IEC 60644, validated at the 4-inch (101.2 mm) creepage distance. This rating is measured under standardized surge waveforms and altitude conditions up to 2000 m. The AFBR-395000RZ achieves this performance via its physical separation, UL-V0 housing, and internal optical barrier - no external components are required to reach the rated 50 kV capability.
Does AFBR-395000RZ support both 3.3 V and 5 V operation?
Yes, AFBR-395000RZ supports both 3.3 V and 5 V supply voltages for both transmitter (VCCTx) and receiver (VCCRx) sections. The recommended operating range is 3.135–4.75 V for 3.3 V systems and 3.465–5.25 V for 5 V systems, with ≤100 mVpp noise on each supply rail. The AFBR-395000RZ maintains full 50 Mbaud signaling performance across both voltage options without configuration changes.
Is AFBR-395000RZ certified to IEC 60747-5-5?
Yes, AFBR-395000RZ is certified to IEC 60747-5-5, which specifies safety and reliability requirements for optocouplers used in reinforced insulation applications. This certification covers lifetime performance under thermal stress, humidity, and voltage endurance testing. The AFBR-395000RZ's qualification includes validation of its 50 kV transient rating, CTI 600 housing, and UL-V0 flammability - all documented in Broadcom's AV02-4884EN datasheet.
What is the propagation delay of AFBR-395000RZ at 50 Mbaud?
The AFBR-395000RZ has a maximum propagation delay of 50 ns at 50 Mbaud, measured from the 1.5 V point of the rising edge of Data_in to the 50% point of the rising edge of Data_out. This value is guaranteed across the full operating temperature range (–40°C to +85°C) and applies to both 3.3 V and 5 V supply configurations. The AFBR-395000RZ also exhibits ≤5 ns device-to-device skew, supporting precise timing in parallel signal paths.
Can AFBR-395000RZ be used in smart grid applications requiring IEC 61850 compliance?
Yes, AFBR-395000RZ is suitable for IEC 61850-compliant smart grid applications due to its 50 kV transient voltage rating, IEC 60747-5-5 certification, and reinforced insulation architecture. Its 101.2 mm creepage distance and 12 kV working voltage capability meet the insulation coordination requirements for process bus and station bus interfaces in digital substations. The AFBR-395000RZ's deterministic 50 ns propagation delay and non-inverted data path support time-critical GOOSE and SV messaging in hardened environments.
