Product details
Overview
SMB10J9.0AHM3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on power and signal lines. It features a 9.0 V stand-off voltage (VWM), 15.4 V maximum clamping voltage (VC) at 10 A peak pulse current, and 1000 W peak pulse power rating with 10/1000 µs waveform - used to safeguard automotive sensor interfaces, DC power rails, and industrial I/O circuits against ESD and load dump transients.
For engineers reviewing the SMB10J9.0AHM3_A/H datasheet, SMB10J9.0AHM3_A/H pinout, SMB10J9.0AHM3_A/H application, or SMB10J9.0AHM3_A/H equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance data, clamping behavior under surge, and halogen-free RoHS-compliant sourcing details - all critical for automotive-grade design-in and long-term supply assurance.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds its 10.0–11.1 V breakdown range (VBR at 1 mA), it rapidly transitions from high-impedance to low-impedance state to divert surge current away from downstream ICs. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and repeatable clamping performance across temperature.
Designed for surface-mount automated assembly, SMB10J9.0AHM3_A/H meets MSL Level 1 per J-STD-020, supports 260 °C lead-free reflow, and achieves 72 °C/W junction-to-ambient thermal resistance on standard 5.0 mm × 5.0 mm copper pads - enabling reliable operation up to +150 °C junction temperature in compact layouts.

FAQ
What is the clamping voltage of SMB10J9.0AHM3_A/H at its rated peak pulse current?
The SMB10J9.0AHM3_A/H has a maximum clamping voltage (VC) of 15.4 V at 64.9 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value represents the worst-case voltage seen by downstream circuitry during a full-rated 1000 W transient event - a key parameter for verifying safe operating margins of protected ICs and passives. The SMB10J9.0AHM3_A/H achieves this clamping performance while maintaining low leakage and stable breakdown characteristics across temperature.
Is SMB10J9.0AHM3_A/H qualified for automotive applications?
Yes, SMB10J9.0AHM3_A/H is AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code suffix "HM3" (halogen-free, RoHS-compliant, AEC-Q101). This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - validating its suitability for under-hood and cabin-mounted automotive electronics such as body control modules, ADAS camera power supplies, and infotainment system inputs. The SMB10J9.0AHM3_A/H meets these requirements in its standard SMB (DO-214AA) package without derating.
What does the "HM3" suffix mean in SMB10J9.0AHM3_A/H?
The "HM3" suffix in SMB10J9.0AHM3_A/H indicates halogen-free, RoHS-compliant construction with AEC-Q101 qualification - distinguishing it from commercial-grade variants like "E3" or "HE3". Specifically, HM3 denotes compliance with JEDEC J-STD-20 MSL Level 1, JESD 201 Class 2 whisker resistance, and UL 94 V-0 flammability rating, using molding compounds free of brominated and chlorinated flame retardants. This makes SMB10J9.0AHM3_A/H appropriate for environmentally regulated markets and safety-critical automotive programs requiring full material disclosure.
How does SMB10J9.0AHM3_A/H compare to SMBJ9.0AHE3_A/H in terms of reliability and application scope?
SMB10J9.0AHM3_A/H offers AEC-Q101 qualification and halogen-free construction, whereas SMBJ9.0AHE3_A/H is commercial-grade, RoHS-compliant but not halogen-free or automotive-qualified. Both share identical electrical specs (VWM = 9.0 V, VC = 15.4 V), but SMB10J9.0AHM3_A/H supports extended temperature operation, enhanced moisture resistance (MSL Level 1), and automotive PPAP documentation. For designs targeting Tier-1 automotive supply chains or global environmental compliance, SMB10J9.0AHM3_A/H is the technically aligned choice - while SMBJ9.0AHE3_A/H remains viable for cost-sensitive industrial applications.
What is the thermal resistance of SMB10J9.0AHM3_A/H, and how does it affect PCB layout?
The SMB10J9.0AHM3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes standard FR-4 PCB with no internal planes - so increasing copper area or adding thermal vias can reduce RθJA and improve surge endurance. For repeated transient events or elevated ambient temperatures, designers should verify junction temperature rise using I2R heating models and ensure TJ stays below +150 °C. The SMB10J9.0AHM3_A/H's low RθJA enables compact placement near protected ICs without dedicated heatsinking.
