概述

Description

1N4448HLP-7 is a variant of the 1N4448 fast-switching silicon diode. The 1N4448 family is a small, high‑speed switching diode commonly used for fast rectification, clipping, and protection in logic and RF circuits. A typical 1N4448 device has a reverse voltage rating around 100 V and a forward current capability on the order of a few hundred milliamps, with a fast recovery time suitable for high‑speed switching applications. The “HLP-7” suffix identifies a specific manufacturer’s packaging/lead form and mechanical variant; exact dimensions, lead style, and mounting options depend on the vendor, so consult the datasheet for that version.
Key points:
- Function: fast-switching silicon diode
- VR≈100 V; IF(AV) ≈ few hundred mA (check exact value for the HLP‑7 variant)
- Applications: high-speed rectification, switching, clamping/protection
- Check datasheet for package details and exact electrical ratings before design.

Features

Here are the key features of the 1N4448HLP-7:
- Fast switching diode (high-speed) for digital and switching circuits
- VR (reverse voltage): 100 V
- IF(AV) (average forward current): 200 mA
- Forward voltage drop: ≈0.9–1.1 V at typical operating current
- Reverse recovery time: a few nanoseconds (very fast)
- Glass-passivated junction for reliability and stability
- Wide operating temperature range (typical -65°C to +150°C)
- Package: HLP-7 (SMD/leadless style as specified by the vendor)
Applications: high-speed switching, rectification in signal circuits, clipping/limiting, logic circuitry, and protection diodes in moderate-current paths.

Package

Axial, through-hole diode in a DO-35 style package (axial lead).

Pinout

Pin count: 2 (anode and cathode).
Function: small‑signal, high‑speed switching diode (used for signal switching, clipping, protection and general low-current rectification). Polarity: cathode is indicated by a band.

Manufacturer

Manufacturer: Diodes Incorporated.
What kind of company: Diodes Inc. is a global semiconductor manufacturer that designs and produces discrete semiconductor components (diodes, transistors, rectifiers), logic and analog ICs, and power-management devices for industrial, consumer, computing and automotive markets.

Application

1N4448HLP-7 is a fast-switching diode. Common application areas include:
- High-speed switching in logic and timing networks
- RF demodulation and envelope detection
- Peak detection and small-signal rectification in power supplies
- Pulse shaping, clipping, and limiter circuits
- Snubber and protection networks in switch-mode power supplies
- RF switching and probe protection in test equipment
- Detectors in sampling and mixer circuits
Note: suitable for low-to-moderate current, high-frequency signal handling.

Equivalent

1N4448HLP-7 is a small-signal fast switching diode equivalent to the common 1N4148/1N914 family. Direct equivalents: 1N4148, 1N914, MMBD4148, LL4148 and other 4148-series SMD variants (SOD523, SOD323 packages). Check package and voltage/current ratings (Vr, If, reverse recovery) to confirm interchangeability.
