Product details
Overview
SMB10J5.0AHM3/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on 5.0 V DC power rails and signal lines. It delivers 1000 W peak pulse power (10/1000 µs), clamps transients to ≤9.2 V at 108.7 A, and features AEC-Q101 qualification for automotive electronics.
For engineers reviewing the SMB10J5.0AHM3/I datasheet, SMB10J5.0AHM3/I pinout, SMB10J5.0AHM3/I application, or SMB10J5.0AHM3/I equivalent, key selection criteria include its 5.0 V standoff voltage, 6.4–7.07 V breakdown range at 10 mA, <1000 nA leakage at VWM, low clamping ratio (VC/VBR ≈ 1.37), and halogen-free RoHS-compliant HM3 suffix with I-reel packaging.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ns) to ESD and lightning-induced surges. Its unidirectional polarity enables integration into DC-biased circuits where reverse conduction must be blocked, and its MSL Level 1 rating supports lead-free reflow up to 260 °C.
The device operates across –55 °C to +150 °C junction temperature, with thermal resistance of 72 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling reliable performance in compact PCB layouts with 5.0 mm × 5.0 mm copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 6.40 V / 7.07 V at 10 mA - Ensures reliable turn-on above normal rail noise while avoiding false triggering |
| VC @ IPPM | 9.2 V at 108.7 A - Limits downstream IC voltage stress during 1000 W surge events |
| ID @ VWM | ≤1000 nA - Negligible leakage current preserves battery life and signal integrity in low-power systems |
| PPPM | 1000 W (10/1000 µs) - Withstands IEC 61000-4-5 Level 4 surges (4 kV line-earth) on 5 V rails |
| TJ max | +150 °C - Supports under-hood automotive placement and industrial ambient conditions |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package

| Cathode | Reverse-biased terminal (marked with band) | Connected to protected line (e.g., 5 V rail); conducts surge current to ground when V > VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable VBR tolerance and long-term reliability under repeated surge stress |
| MSL Level 1 (260 °C peak) | Supports standard lead-free SMT reflow without popcorn cracking or delamination |
| Halogen-free & RoHS-compliant (HM3) | Meets automotive environmental standards and eliminates corrosive halogen emissions during soldering |
| Low incremental surge resistance | Minimizes VC rise under high di/dt, improving clamping precision for fast transients |
| 100 A IFSM (8.3 ms half-sine) | Handles inrush currents and repetitive switching surges without degradation |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 5 V supply lines feeding ADAS camera modules, body control units, or infotainment ECUs from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between 5 V rail and chassis ground to clamp positive transients only. Use Value: Maintains VWM = 5.0 V compatibility with LDO outputs while limiting VC to 9.2 V-well below typical 12 V tolerant IO thresholds. | Use Scenario: Safeguarding analog sensor inputs (e.g., pressure, temperature) connected to microcontrollers in factory automation PLCs. IC Role / Device Role / Timing Role: TVS mounted directly at connector entry point to shunt ESD (IEC 61000-4-2 ±8 kV contact) and inductive kickback from solenoid drivers. Use Value: Sub-1000 nA leakage ensures no measurable offset error in 16-bit ADC front-ends; fast response prevents latch-up in sensitive analog circuitry. |
| Consumer USB Power Delivery | Telecom Base Station DC Feeds |
Use Scenario: Overvoltage protection on 5 V VBUS lines in USB-C PD sink applications subject to hot-plug transients and adapter faults. IC Role / Device Role / Timing Role: Unidirectional TVS placed upstream of USB PD controller to prevent damage during VBUS overvoltage events. Use Value: 1000 W PPPM handles worst-case fault energy without failure; AEC-Q101 qualification adds margin for extended consumer product lifetime. | Use Scenario: Secondary-side surge suppression on -48 V DC telecom power distribution boards exposed to lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Used in parallel arrays with other SMB10J devices to share high-current surge duty across multiple paths. Use Value: Low RθJL = 20 °C/W enables effective heat spreading into copper planes, sustaining repeated 10/1000 µs surges without thermal runaway. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0AHE3/52 | Same electrical specs; RoHS-compliant E3 suffix (not halogen-free); 7" reel (52) vs. 13" reel (I) | Lacks AEC-Q101 qualification; suitable for commercial/industrial but not automotive end-equipment | Select when halogen-free requirement is absent and AEC-Q101 is not mandated. |
| SMCJ5.0A-Q | Higher PPPM (1500 W), larger SMC (DO-214AB) package, same VWM/VBR/VC | Requires larger PCB footprint; better suited for higher-energy surge environments (e.g., AC mains input stages) | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 and board space allows SMC footprint. |
Compared with SMBJ5.0AHE3/52 and SMCJ5.0A-Q, SMB10J5.0AHM3/I uniquely combines AEC-Q101 qualification, halogen-free construction, and SMB footprint-making it optimal for space-constrained automotive modules requiring full environmental compliance and high surge immunity.

FAQ
What is the clamping voltage of SMB10J5.0AHM3/I at its maximum rated surge current?
The SMB10J5.0AHM3/I clamps to a maximum of 9.2 V when subjected to its peak pulse current of 108.7 A (10/1000 µs waveform). This value is measured under standardized test conditions and ensures protected circuits remain within safe voltage margins during transient events. The SMB10J5.0AHM3/I achieves this with minimal voltage overshoot due to its low incremental surge resistance and fast junction response.
Is SMB10J5.0AHM3/I suitable for automotive applications?
Yes, SMB10J5.0AHM3/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction with automotive-grade reliability validation. It is explicitly intended for use in automotive subsystems such as body electronics, ADAS sensors, and infotainment power rails where robust transient immunity and long-term stability are required. The SMB10J5.0AHM3/I meets all stress tests defined in AEC-Q101, including temperature cycling and high-temperature reverse bias.
What does the "HM3/I" suffix mean in SMB10J5.0AHM3/I?
The "HM3" suffix denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification; "I" specifies packaging in a 13-inch diameter plastic tape-and-reel format containing 3200 units. This distinguishes SMB10J5.0AHM3/I from variants like HE3/B/H (7-inch reel, 750 units) or E3/52 (commercial-grade, non-automotive). The SMB10J5.0AHM3/I suffix confirms full compliance with automotive environmental and packaging requirements.
How does SMB10J5.0AHM3/I compare to bidirectional TVS diodes like SMB8J5.0CA?
SMB10J5.0AHM3/I is unidirectional and rated for 1000 W PPPM, whereas SMB8J5.0CA is bidirectional with 800 W PPPM and symmetric clamping. The SMB10J5.0AHM3/I offers higher surge capability and lower clamping voltage in DC-biased applications, but cannot protect AC signals or floating lines. Use SMB10J5.0AHM3/I where polarity is fixed (e.g., 5 V rail to ground); choose SMB8J5.0CA only when bidirectional protection is mandatory.
What PCB layout guidance applies to SMB10J5.0AHM3/I for optimal thermal and electrical performance?
For optimal performance, mount SMB10J5.0AHM3/I on minimum 5.0 mm × 5.0 mm copper pads per terminal, using short, wide traces to minimize inductance. Thermal relief should be minimized to maximize heat dissipation, leveraging its RθJL = 20 °C/W. Avoid vias near terminals that interrupt copper mass. The SMB10J5.0AHM3/I datasheet specifies this pad layout to sustain its 1000 W rating and prevent localized overheating during surge events.
