Product details
Overview
HFBR-3810Z from Broadcom is a 650 nm fiber-optic link transceiver pair with integrated transmitter and receiver, supporting DC to 10 MBaud NRZ signaling, 12 kV transient voltage suppression per IEC 60664-1, and CMOS/TTL-compatible output - used in industrial motor drives and inverter control circuits requiring galvanic isolation on a single PCB.
For engineers reviewing the HFBR-3810Z datasheet, pinout, applications, or equivalent options, key selection criteria include its 25.1 mm air-gap clearance, 5 V supply operation, 95 ns typical propagation delay, RoHS compliance, and laser Class 1 safety certification per IEC 60825:2001 Amendment.
Technical Context
The HFBR-3810Z implements a direct-coupled optical link architecture: the LED-based transmitter operates at 650 nm with peak forward current up to 90 mA, while the photodiode-based receiver delivers CMOS/TTL logic-level outputs without external digitizing circuitry. It requires no data encoding and supports true DC–10 MBaud signal transmission.
Its isolation performance is defined by physical air-gap dimensions (25.1 mm clearance, 28.7 mm creepage) and rated impulse voltage of 12 kV under IEC 60664-1 Overvoltage Category 4 conditions - enabling use in high-noise, high-voltage industrial environments where reinforced insulation is mandated.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Signaling Rate | DC to 10 MBaud NRZ - supports unencoded digital signals from static logic levels to 10 Mbit/s serial streams. |
| Air-Gap Clearance | 25.1 mm - enables 12 kV transient voltage suppression and meets IEC 60664-1 reinforced insulation requirements. |
| Supply Voltage | 4.75–5.25 V - tightly regulated 5 V rail required; noise must be <100 mVpp (DC–10 MHz). |
| Propagation Delay | Typ. 95 ns - fixed latency from input edge to output edge, critical for timing-critical feedback loops in inverters. |
| Output Logic Levels | VOH ≥ 4.2 V, VOL ≤ 0.4 V - directly interfaces standard 5 V CMOS/TTL logic without level-shifting. |
| Operating Temperature | –40°C to +85°C - qualified for industrial ambient conditions including motor drive cabinets and power converters. |
| Laser Safety Class | IEC 60825:2001 Amendment Class 1 - inherently safe; no user-accessible hazardous optical radiation. |
Pinout & Package
HFBR-3810Z uses a 8-pin DIP-style through-hole package with internal shield pins omitted (pins 9–11 not present), measuring 31.27 mm × 10.16 mm × 10.96 mm (L×W×H). The housing provides reinforced insulation via nonconductive mold compound and defined air gaps.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Transmitter Anode | LED anode connection; requires series current-limiting resistor (e.g., 2 kΩ) driven by logic-level input. |
| 2 | Transmitter Cathode | LED cathode return; connects to ground or driver low-side switch. |
| 3, 4, 5, 7 | GND | Dedicated ground terminals for transmitter, receiver, and shielding - reduce crosstalk and improve noise immunity. |
| 6 | Receiver VCC | 5 V supply for receiver IC; decoupling capacitor (0.1 µF) required near pin. |
| 8 | Receiver Data_OUT | CMOS/TTL-compatible digital output; sinks/sourcing up to ±16 mA, compatible with 74HC/ACT logic families. |
Key Features
| Feature | Design Value |
|---|---|
| DC-coupled receiver output | Eliminates need for AC coupling capacitors or data recovery PLLs - simplifies PCB layout and reduces BOM count. |
| 12 kV transient voltage suppression | Meets IEC 60664-1 overvoltage Category 4 - enables direct interface with high-voltage gate drivers without external TVS. |
| Galvanic isolation on single PCB | 25.1 mm air gap and molded housing provide reinforced insulation - avoids separate isolated boards or transformers. |
| RoHS-compliant & laser Class 1 | Complies with environmental regulations and eliminates laser safety interlocks or labeling requirements in end equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fiber-optic digital isolation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HFBR-3810MSZ | 20.1 mm clearance (vs. 25.1 mm), 23.1 mm creepage, rated for 2000 m altitude (vs. 3000 m), same signaling rate and output logic. | Approved for lower-altitude industrial deployments; not suitable where 3000 m operation or 12 kV surge margin is required. | Select HFBR-3810MSZ only if footprint compatibility and cost are prioritized over maximum surge rating and altitude range. |
| ACPL-M61T | LED+phototransistor optocoupler (not fiber-based); 10 MBaud max, 3750 Vrms isolation, 200 ns propagation delay, no air-gap specification. | Lacks fiber-optic noise immunity and standardized 12 kV surge rating; suited for lower-noise, non-safety-critical applications. | Choose ACPL-M61T when board space is constrained and full IEC 60664-1 Category 4 compliance is not mandated. |
Compared with HFBR-3810MSZ and ACPL-M61T, the HFBR-3810Z uniquely delivers certified 12 kV surge suppression via 25.1 mm air gap and 3000 m altitude rating - making it the only option among the three qualified for high-reliability inverter gate drive and safety-critical PLC I/O.

FAQ
What is the maximum signaling rate supported by the HFBR-3810Z?
The HFBR-3810Z supports a maximum signaling rate of 10 MBaud for NRZ (non-return-to-zero) data formats. This is specified across the full operating temperature range (–40°C to +85°C) and applies to both rising and falling edges without encoding. The device maintains pulse width variation within ±10 ns at 10 MBaud, ensuring reliable high-speed digital transmission in real-time control applications such as motor drives and inverters.
Does the HFBR-3810Z require external data encoding or clock recovery circuitry?
No, the HFBR-3810Z does not require external data encoding or clock recovery circuitry. Its receiver is DC-coupled and delivers native CMOS/TTL logic-level outputs, enabling direct interface with microcontrollers and logic families. This eliminates the need for PLLs, Manchester encoders, or AC-coupling capacitors - simplifying design and reducing bill-of-materials cost compared to more complex isolation solutions.
What is the meaning of "12 kV transient voltage suppression" for the HFBR-3810Z?
The "12 kV transient voltage suppression" refers to the HFBR-3810Z's rated impulse voltage per IEC 60664-1, achieved via its 25.1 mm air-gap clearance and reinforced insulation structure. It indicates the device can withstand 12 kV surge pulses (1.2/50 µs waveform) without breakdown - a critical specification for protecting downstream logic in high-voltage industrial systems like variable-frequency drives and grid-tied inverters.
Is the HFBR-3810Z pin-compatible with the HFBR-3810MSZ?
The HFBR-3810Z and HFBR-3810MSZ share identical 8-pin through-hole footprints and pin functions, but HFBR-3810Z omits pins 9–11 (shield option), whereas HFBR-3810MSZ includes them. PCB layouts designed for HFBR-3810Z will accept HFBR-3810MSZ, but not vice versa without modification. Both parts use the same recommended drive circuit and operate identically at the signal level.
What safety certifications apply to the HFBR-3810Z?
The HFBR-3810Z is certified as laser Class 1 per IEC 60825:2001 Amendment, meaning it emits no hazardous optical radiation under normal or single-fault conditions. It also meets IEC 60664-1 for reinforced insulation with 12 kV impulse voltage rating, Overvoltage Category 4, Pollution Degree 3, and Material Group II - supporting compliance with UL 61800-5-1 and EN 61800-5-1 in industrial drive applications.
