Product details
Overview
VS-10BQ100HM3/5BT from Vishay Semiconductors is a high-performance surface-mount Schottky rectifier rated for 1 A average forward current and 100 V reverse voltage, featuring low 0.59 V forward drop at 1 A and 125 °C junction temperature. It serves as a freewheeling or reverse-battery protection diode in compact DC/DC converters, automotive battery management systems, and industrial power supplies.
For engineers reviewing the VS-10BQ100HM3/5BT datasheet, VS-10BQ100HM3/5BT pinout, VS-10BQ100HM3/5BT application, or VS-10BQ100HM3/5BT equivalent, key selection criteria include its AEC-Q101 qualification, SMB (DO-214AA) package thermal resistance of 36 °C/W (junction-to-lead), 1.0 mJ non-repetitive avalanche energy rating, and 10,000 V/μs dV/dt capability for fast-switching environments.
Technical Context
This Schottky rectifier employs a planar silicon die with guard ring structure to enhance ruggedness and long-term reliability under repetitive surge and thermal stress. Its low VF and 65 pF junction capacitance at 5 V enable high-frequency operation in synchronous rectification and flyback snubber circuits.
The device operates across -55 °C to +175 °C junction temperature range and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow peak, supporting automotive-grade assembly requirements without derating at board-level mounting.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS1H100S | Same SMB package, 1 A/100 V rating, but VF = 0.72 V @ 1 A/125 °C; no AEC-Q101 qualification | Not approved for automotive under-hood use; limited to commercial-grade power supplies | Select when cost sensitivity outweighs automotive compliance and thermal performance |
| ON Semi SB1100-T3 | SMB package, 1 A/100 V, VF = 0.63 V @ 1 A/125 °C; RthJL = 45 °C/W; not AEC-Q101 qualified | Larger thermal resistance increases junction temperature rise by ~30 % at same power dissipation | Choose only if legacy design uses this part and qualification recertification is impractical |

FAQ
What is the maximum junction temperature rating for VS-10BQ100HM3/5BT?
The VS-10BQ100HM3/5BT has a maximum junction temperature (TJ max.) of +175 °C, enabling reliable operation in under-hood automotive environments and sealed industrial enclosures without active cooling. This rating is validated per AEC-Q101 stress testing and supported by its 36 °C/W junction-to-lead thermal resistance, allowing sustained 1 A conduction at elevated ambient temperatures when properly mounted.
Is VS-10BQ100HM3/5BT suitable for automotive applications?
Yes, the VS-10BQ100HM3/5BT is AEC-Q101 qualified and explicitly designed for automotive use, including battery protection, body control modules, and DC/DC converters in passenger vehicles and commercial fleets. Its guard ring construction, MSL Level 1 reflow compatibility, and operation up to +175 °C junction temperature meet stringent automotive reliability and manufacturability requirements.
What does the 'M3' suffix mean in VS-10BQ100HM3/5BT?
The 'M3' suffix in VS-10BQ100HM3/5BT indicates halogen-free, RoHS-compliant construction with lead (Pb)-free terminations-fully aligned with EU ELV Directive and China RoHS standards. This ensures compatibility with lead-free reflow soldering processes peaking at 260 °C and supports environmentally responsible manufacturing without compromising electrical or thermal performance.
How does the forward voltage of VS-10BQ100HM3/5BT compare at different temperatures?
At 25 °C, VS-10BQ100HM3/5BT exhibits VF = 0.75 V at 1 A; at 125 °C, VF drops to 0.59 V due to Schottky barrier physics. This negative temperature coefficient improves thermal stability in high-current applications, reducing conduction loss as temperature rises-unlike PN diodes whose VF increases with temperature.
What is the avalanche energy rating of VS-10BQ100HM3/5BT and how is it applied?
The VS-10BQ100HM3/5BT is rated for 1.0 mJ non-repetitive avalanche energy (EAS) at TJ = 25 °C with IAS = 0.5 A and L = 8 mH. This rating allows safe clamping of inductive turn-off transients in relay drivers, solenoid controls, and motor gate drivers-absorbing stored magnetic energy without failure, provided single-event conditions remain within specified limits.
