Product details
Overview
VS-10BQ030HM3/5BT from Vishay Semiconductors is a surface-mount AEC-Q101-qualified Schottky rectifier with 30 V reverse voltage rating, 1.0 A average forward current, and ultra-low 0.30 V forward voltage at 1.0 A and 125 °C. It features SMB (DO-214AA) package, 3.0 mJ non-repetitive avalanche energy, and is designed for reverse battery protection and freewheeling in automotive power modules.
For engineers reviewing the VS-10BQ030HM3/5BT datasheet, VS-10BQ030HM3/5BT pinout, VS-10BQ030HM3/5BT application, or VS-10BQ030HM3/5BT equivalent, key selection criteria include low VF at high temperature, MSL Level 1 solderability, halogen-free RoHS-compliant construction, and validated ruggedness for automotive-grade transient stress.
Technical Context
This Schottky rectifier employs a planar guard-ringed die structure to suppress edge breakdown and improve long-term reliability under repetitive surge and thermal cycling. Its low junction capacitance (200 pF at 5 V) and high dV/dt capability (10,000 V/μs) support fast-switching DC/DC converter topologies.
The device operates across –55 °C to +150 °C junction temperature range with RthJL = 25 °C/W (junction-to-lead), enabling direct PCB thermal coupling without heatsinks in space-constrained automotive modules where thermal runaway risk must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 30 V maximum DC reverse voltage - supports 24 V automotive systems with 2× safety margin against load dump transients |
| IF(AV) | 1.0 A average forward current - rated for continuous conduction in buck converter freewheel paths at TL = 106 °C |
| VF | 0.30 V at 1.0 A, 125 °C - reduces conduction loss by >40% vs. standard silicon diodes in high-temp battery charging circuits |
| EAS | 3.0 mJ non-repetitive avalanche energy - withstands inductive kickback from solenoid drivers without failure |
| RthJL | 25 °C/W junction-to-lead - enables efficient heat transfer to PCB copper pour, critical for compact engine control unit layouts |
| CT | 200 pF at 5 V - minimizes switching losses and EMI in 500 kHz–1 MHz SMPS designs |
| dV/dt | 10,000 V/μs - prevents false turn-on during fast voltage transients in motor drive gate driver supplies |
Pinout & Package
SMB (DO-214AA) surface-mount package with cathode band marking; 0.220" × 0.130" footprint, 0.086" height, and 0.10 g mass. Designed for reflow soldering per J-STD-020 MSL Level 1 (260 °C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to switched high-side node (e.g., buck converter switch node); must handle 430 A surge pulses |
| Cathode | Forward current exit / reverse blocking terminal | Connected to output rail or ground return; marked by molded band; carries full load current and absorbs avalanche energy |
Key Features
| Feature | Design Value |

| Guard ring structure | Prevents edge-initiated breakdown under high dv/dt and high temperature, extending lifetime in automotive under-hood environments |
| AEC-Q101 qualification | Validated for automotive applications including engine control, body electronics, and ADAS power rails per stress test requirements |
| Halogen-free, Pb-free, RoHS-compliant (M3) | Meets global environmental regulations and enables compatibility with lead-free reflow profiles without compromising reliability |
| Low thermal resistance (RthJL = 25 °C/W) | Allows direct thermal path to PCB copper, eliminating need for external heatsinks in space-constrained modules |
| High surge robustness (IFSM = 430 A) | Survives short-circuit events and inductive load disconnection in 12 V/24 V vehicle electrical systems |
Applications
| Reverse Battery Protection | Automotive DC/DC Converter Freewheeling |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS1L30A | Same SMB package, 30 V VR, but higher VF = 0.49 V @ 1 A, 125 °C; no AEC-Q101 qualification | Not qualified for automotive under-hood use; suitable only for industrial or consumer power supplies | Select when AEC-Q101 compliance is not required and cost is prioritized over thermal performance |
| SS13-E3/5AT | 1.0 A, 30 V, SMB package, but lower EAS = 1.5 mJ and no guard ring; RoHS-compliant but not halogen-free | Limited surge endurance in solenoid or motor driver applications; not recommended for engine bay deployment | Choose for cost-sensitive consumer adapters where avalanche robustness is secondary |

FAQ
What is the maximum junction temperature rating for the VS-10BQ030HM3/5BT?
The VS-10BQ030HM3/5BT has a maximum junction temperature (TJ) of +150 °C, verified per AEC-Q101 stress testing. This rating allows reliable operation in under-hood automotive environments where ambient temperatures exceed 105 °C, provided thermal design maintains junction temperature below this limit using the specified RthJL = 25 °C/W path to PCB copper.
Is the VS-10BQ030HM3/5BT compatible with lead-free reflow soldering processes?
Yes, the VS-10BQ030HM3/5BT is rated MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C. Its halogen-free, Pb-free terminations and robust SMB package ensure compatibility with standard lead-free reflow profiles without delamination or solder joint integrity issues.
Does the VS-10BQ030HM3/5BT have AEC-Q101 qualification documentation available?
Yes, the VS-10BQ030HM3/5BT is explicitly AEC-Q101 qualified, as confirmed in its Vishay datasheet (Document Number: 95740) and ordering code suffix 'H'. Full qualification reports-including temperature cycling, HTRB, and ESD testing-are available upon request from Vishay's automotive support team.
What is the reverse leakage current of the VS-10BQ030HM3/5BT at 125 °C?
The VS-10BQ030HM3/5BT exhibits a maximum reverse leakage current (IRM) of 15 mA at rated VR = 30 V and TJ = 125 °C. This value is measured under steady-state conditions and is critical for evaluating standby power loss in always-on automotive modules such as telematics control units.
Can the VS-10BQ030HM3/5BT replace a standard silicon rectifier in an existing 24 V power supply?
Yes, the VS-10BQ030HM3/5BT can directly replace silicon rectifiers in 24 V power supplies where low forward voltage and fast recovery are beneficial. Its 0.30 V VF at 125 °C reduces conduction loss significantly, but layout must verify SMB footprint compatibility and thermal relief design to manage its 25 °C/W RthJL.
