Product details
Overview
VTVS63GSMF-HM3-18 from Vishay Semiconductors is a unidirectional 400 W TransZorb® transient voltage suppressor diode in SMF (DO-219AB) package, with 63.0 V stand-off voltage (VRWM), ±2 % breakdown voltage tolerance, and 108 A peak pulse current (IPPM) under 10/1000 μs waveform - designed for robust ESD and surge protection on automotive power rails and industrial I/O lines.
For engineers reviewing the VTVS63GSMF-HM3-18 datasheet, VTVS63GSMF-HM3-18 pinout, VTVS63GSMF-HM3-18 application, or VTVS63GSMF-HM3-18 equivalent, key selection criteria include clamping voltage (108 V), low leakage (<0.05 μA at VRWM), halogen-free construction, AEC-Q101 qualification, and compatibility with SOD-123W footprint constraints.
Technical Context
This device operates as a unidirectional avalanche diode, triggering at reverse breakdown to clamp transients above 63.0 V while maintaining <108 V clamping at 108 A. Its 1.08 mm height and 3.9 × 1.9 mm footprint enable high-density placement on space-constrained PCBs.
It delivers ±30 kV ESD immunity per IEC 61000-4-2 (contact/air), supports reflow and wave soldering up to 260 °C, and maintains stable operation from –55 °C to +175 °C junction temperature - meeting automotive-grade reliability requirements without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W (10/1000 μs waveform - sustains automotive load-dump surges) |
| Stand-off Voltage (VRWM) | 63.0 V (maximum continuous reverse operating voltage before conduction) |
| Breakdown Voltage (VBR) | 73.01–75.99 V at IT = 1 mA (±2 % tolerance ensures precise trigger threshold) |
| Clamping Voltage (VC) | 108 V at IPPM = 108 A (limits downstream IC stress during surge events) |
| Leakage Current (IR) | <0.05 μA at VRWM (minimizes standby power loss in battery-powered systems) |

FAQ
What is the maximum clamping voltage of the VTVS63GSMF-HM3-18 under surge conditions?
The VTVS63GSMF-HM3-18 has a maximum reverse clamping voltage (VC) of 108 V at 108 A peak pulse current (IPPM) using the 10/1000 μs waveform. This value is guaranteed across temperature and ensures downstream components rated for ≤120 V remain within safe operating limits during standardized surge events.
Is the VTVS63GSMF-HM3-18 qualified for automotive applications?
Yes, the VTVS63GSMF-HM3-18 is AEC-Q101 qualified, meaning it has passed stress tests including high-temperature operating life, temperature cycling, and ESD robustness required for automotive powertrain and body electronics. Its 175 °C maximum junction temperature further supports under-hood deployment.
Does the VTVS63GSMF-HM3-18 support lead-free reflow soldering?
Yes, the VTVS63GSMF-HM3-18 is rated for peak reflow temperatures up to 260 °C and complies with J-STD-020 MSL Level 1 - allowing unlimited floor life and standard Pb-free reflow profiles without pre-baking or special handling.
What is the leakage current specification for VTVS63GSMF-HM3-18 at its stand-off voltage?
The VTVS63GSMF-HM3-18 exhibits a maximum reverse leakage current (IR) of 0.05 μA at its 63.0 V stand-off voltage (VRWM) and 25 °C ambient temperature. This ultra-low leakage preserves battery life in always-on automotive modules and avoids false triggering in high-impedance sensing circuits.
How does the ±2 % breakdown voltage tolerance of VTVS63GSMF-HM3-18 improve system design?
The ±2 % VBR tolerance of VTVS63GSMF-HM3-18 enables tighter coordination with downstream overvoltage protection thresholds and reduces design margin uncertainty. For example, in a 63 V rail, it guarantees conduction begins between 73.01 V and 75.99 V - avoiding premature clamping or delayed response seen with ±5 % variants like VTVS63ASMF-HM3-18.
