Product Description
Vishay SMF18A-E3-08 is a 1-element uni-directional transient voltage suppressor (TVS) diode with high surge capability and ESD protection designed for robust semiconductor protection in automotive and industrial electronics.
This surface mount diode utilizes a DO-219 package optimized for compact PCB layouts and enhanced thermal performance. Its peak pulse power dissipation of 200W with a 10/1000μs waveform at 0.01% duty cycle provides excellent protection against voltage transients and load dump conditions.
The device offers a low clamping voltage of 26V with a minimum breakdown voltage of 17.8V and maximum reverse stand-off voltage of 18V, ensuring circuit components remain protected within safe operating voltages. The maximum reverse leakage current is limited to 100nA, contributing to energy efficiency and low quiescent power loss.
Meeting automotive standard AEC-Q101 and qualified for enhanced electrostatic discharge (ESD) protection, the diode safeguards sensitive electronics such as ICs, MOSFETs, signal lines for sensors, consumer electronics, computers, telecommunications, and industrial controls.
Its compact size, with length 2.9mm, width 1.9mm, and height 1.08mm, allows for surface mounting on densely packed circuit boards, while providing a junction temperature operating range from -55°C to 150°C for harsh environments.
200W peak pulse power capability with low incremental surge resistance. Uni-directional single diode configuration with low clamping voltage. ESD protection meeting AEC-Q101 automotive standard and human body model H3B > 8 kV.
Compact DO-219 surface mount package supporting compact PCB designs. Wide operating temperature range from -55°C to 150°C for industrial use. Applications include automotive load dump, IC and MOSFET protection, telecommunications and industrial equipment.
The Vishay SMF18A-E3-08 diode is manufactured in China and designed to meet demanding industrial, automotive, and consumer electronic transient voltage suppression needs. Explore more TVS Diodes and semiconductor devices in the Electronics & Electricals category on EnvMart.
