Overview
P6SMB110CAHM3_B/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 110 V standoff voltage (VWM), 152 V clamping voltage (VC) at 3.9 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 μs). It protects signal lines and power rails in automotive sensor units, industrial I/O modules, and telecom interface circuits against ESD and inductive switching transients.
For engineers reviewing the P6SMB110CAHM3_B/H datasheet, P6SMB110CAHM3_B/H pinout, P6SMB110CAHM3_B/H application, or P6SMB110CAHM3_B/H equivalent, this device delivers AEC-Q101 qualification, halogen-free RoHS compliance, MSL Level 1 moisture sensitivity, and verified bidirectional clamping performance with low incremental surge resistance and fast response time.
Technical Context
This TVS operates symmetrically in both directions, with breakdown voltage (VBR) of 105–116 V at 1 mA test current and maximum reverse leakage (ID) ≤1.0 μA at 94.0 V standoff. Its thermal resistance junction-to-ambient (RθJA) is 100 °C/W on standard 0.2" × 0.2" copper pads, supporting reliable transient energy dissipation without external heatsinking in space-constrained layouts.
The device uses glass-passivated silicon junction technology, enabling stable clamping under repetitive 0.01% duty-cycle surges and compatibility with automated SMT placement. Its SMB package meets UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance requirements.
Key Specifications
