Overview
The SM8S series TVS diodes feature an SMTO-263 package with modified leads. They protect sensitive electronic equipment from voltage transient events caused by lightning strikes and inductive load switching.
Applications
- TVS components are ideal for protecting I/O interfaces, VCC buses, and other vulnerable circuits in telecommunications, computer, industrial, and consumer electronics applications.
Key features
- 7000W peak pulse power capability at 10/1000μs waveform, repetition rate (duty cycle) 0.01%
- SMTO-263 low-profile surface mount package, minimizing PCB footprint
- Typical failure mode is short circuit due to overvoltage or overcurrent
- Whisker testing per Table 4a and 4c of JEDEC JESD201A, passing Level 1 and Level 2
- IEC 61000-4-2 ESD 30kV (air), 30kV (contact)
- Glass passivated chip junction
- Low dynamic resistance
- VBR@TJ = VBR@25°C×(1 + αT×(T - 25)) (αT: temperature coefficient, typical value 0.1%)
- UL recognized compound, meeting V-0 flammability rating
- Halogen-free and RoHS compliant
- Lead-free E3 indicates second-level interconnect lead-free, terminal plating material is tin (Sn) (IPC/JEDEC J-STD-609A.01)
- Recognized by UL 497B as an isolated loop circuit protector
