概述

Description

ACPL-K376-500E is Broadcom/Avago’s ACPL family high-speed optically isolated digital optocoupler. It provides galvanic isolation between a low-voltage input and a high-voltage output, enabling safe signal transfer across an isolation barrier. The K376-500E variant targets higher-speed, industrial-grade performance with an extended temperature range and a multi-kV isolation rating (typical several kilovolts RMS). Input is an LED; output is a logic-compatible (TTL/CMOS) stage on the isolated side. Common uses include driving IGBTs/MOSFETs in motor drives and switch-mode power supplies, as well as isolated digital interfaces. Benefits: fast switching, good common-mode transient immunity, compact package, and robust isolation. For exact electrical specs (propagation delay, CTR, input current, VOH/VOL, isolation voltage), consult the official datasheet.

Features

Here are the typical features of ACPL-K376-500E (optically isolated gate/driver style device):
- Reinforced isolation: up to 5 kV RMS between input and output
- High-speed optocoupler with a fast, totem-pole style output suitable for IGBT/MOSFET gate drive
- Logic-compatible LED input with guaranteed CTR over temperature
- High common-mode transient immunity (CMTI) for rugged EMI environments
- Wide operating temperature range (typically -40°C to +125°C)
- Small package options (8-pin SOIC/DIP) and RoHS-compliant
- Designed for direct use in gate-drive and signal-isolation applications
- Safety/qualification support (UL/CE/VDE style safety approvals depending on variant)
Note: Please consult the exact datasheet for precise electrical specifications (CTR ranges, propagation delays, input/output current, sensitivity, and package variants) for your specific lot.

Package

8-pin DIP (DIP-8) through-hole package.

Pinout

- Pin count: 8 pins (DIP-8/SOIC-8)
- Function: Single‑channel optically isolated amplifier (ACPL series). It provides galvanic isolation between input and output via an LED input and an isolated, amplified output.
