Product Description

onsemi 1N4149TR is a small signal diode packaged in a 2-pin DO-35 through-hole mount, designed for general-purpose electronic switching and signal processing applications. Rated at a maximum continuous forward current of 500 mA and reverse voltage of 100 V, this diode provides reliable operation in compact form factors.

The diode features a fast recovery time of 4 nanoseconds and a low maximum forward voltage of 1 V, which is essential for high-speed switching circuits with minimal power dissipation. It supports a peak non-repetitive forward surge current of 4 A, enabling it to withstand transient surges without damage.

With its small dimensions - length 2.29 mm, diameter 1.91 mm, and height 4.56 mm - this diode is well suited for crowded PCBs and through-hole assembly. It is qualified for operation up to 175°C, making it suitable for industrial, laboratory, and consumer electronics environments requiring robust performance under thermal stress.

This high conductance fast diode is not automotive certified but widely used in power supplies, signal conditioning, switching circuits, and general semiconductor applications within the electronics and electrical industries.

High-speed diode optimized for switching applications. Compact DO-35 packaging for through-hole PCB mounting. Robust voltage and current ratings for reliable performance. Fast 4 ns reverse recovery time minimizes switching losses.

Durable operation up to 175°C ambient temperature. Applications include power supplies, signal processing, and electronic switching. Explore more semiconductors and discrete diodes at EnvMart to suit various industrial and electronic system design needs.
