Overview
SMBJ90CD-M3/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 90 V standoff voltage (VWM), 102–109 V breakdown voltage (VBR) at 1 mA, 144 V maximum clamping voltage (VC) at 4.17 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the SMBJ90CD-M3/H datasheet, SMBJ90CD-M3/H pinout, SMBJ90CD-M3/H application, or SMBJ90CD-M3/H equivalent, this page delivers verified electrical parameters, bidirectional polarity confirmation, thermal resistance (RθJA = 125 °C/W), MSL Level 1 moisture sensitivity, and RoHS-compliant halogen-free construction - all critical for ESD/surge protection design-in and BOM validation.
Technical Context
This device operates as a voltage-clamping protector in bidirectional mode, responding to transient overvoltages in either polarity without requiring external polarity management. Its silicon avalanche structure enables sub-nanosecond response time and low incremental surge resistance, ensuring effective suppression of inductive switching spikes and lightning-induced surges.
Rated for -55 °C to +150 °C junction temperature, it supports industrial and telecom applications where sustained reliability under thermal stress is required. The SMB (DO-214AA) package provides 1.0 W power dissipation at 25 °C ambient and 5.0 W at 50 °C case temperature when mounted on minimum recommended pad layout.
