Overview of SMF24A by Littelfuse Inc.
The SMF24A by Littelfuse Inc. is a unidirectional Transient Voltage Suppressor (TVS) Diode, designed to protect electronic circuits against transient voltage spikes. Part of the SMF Series, it is specified with a 200W peak pulse power dissipation, a reverse stand-off voltage (Vrwm) of 24V, and a maximum clamping voltage (Vc Max) of 38.9V. This diode’s case style is SOD-123Fl, featuring 2 pins for connections. With its silicon diode element material, the SMF24A offers excellent clamping capability, ensuring the protected circuitry remains safe from voltage transients.
Included features such as a breakdown voltage range from 26.7V to 29.5V, with a nominal value of 28.1V, singles out this component for its precise response to over-voltage conditions. It is notable for its compliance with IEC-61000-4-2 and 4-4 standards, UL recognition, and its capability to handle a non-repetitive peak reverse power dissipation of 1000 W momentarily. Its operational temperature range is wide, from -65 °C to 150 °C, accommodating various environmental conditions. Moreover, the SMF24A is designed for surface mount and features a moisture sensitivity level of 1, signifying its resilience in humid environments. The diode’s lead finish is matte tin, which is desirable for preventing oxidation and ensuring longevity.
