Product details
Overview
P6SMB100AHM3_B/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 100 V standoff voltage (VWM), 137 V maximum clamping voltage (VC) at 4.4 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 μs waveform). It protects sensitive ICs and MOSFETs against inductive switching transients and ESD in automotive and industrial power rails.
For engineers reviewing the P6SMB100AHM3_B/H datasheet, P6SMB100AHM3_B/H pinout, P6SMB100AHM3_B/H application, or P6SMB100AHM3_B/H equivalent, this AEC-Q101 qualified, halogen-free, RoHS-compliant TVS offers verified clamping performance, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability automotive ECUs and industrial motor drives.
Technical Context
This unidirectional TVS operates with a 100 V reverse standoff voltage (VWM) and a breakdown voltage range of 95.0–105 V at 1 mA test current, ensuring reliable blocking below threshold while triggering fast clamping during overvoltage events. Its 137 V clamping voltage at 4.4 A (10/1000 μs) limits transient energy delivered to downstream circuitry.
Designed for surface-mount assembly on standard PCB pads (0.2" × 0.2"), it delivers 600 W peak pulse power handling, 5.0 W steady-state power dissipation, and thermal resistance of 100 °C/W (junction-to-ambient), with operating junction temperature up to +150 °C - supporting under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff) | 100 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin for 12 V/24 V/48 V rail protection. |
| VBR (Breakdown) | 95.0–105 V at 1 mA - Confirmed avalanche initiation window; ensures predictable turn-on within ±5 % tolerance. |
| VC (Clamping) | 137 V at 4.4 A (10/1000 μs) - Peak voltage seen by protected device during worst-case transient; enables robust I/O and power-stage protection. |
| PPPM | 600 W - Sustains high-energy surges (e.g., ISO 7637-2 Pulse 1/2a/5a) without failure; validated per JEDEC standards. |
