Product details
Overview
SMCJ9.0AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, with 9.0 V stand-off voltage (VWM), 15.4 V maximum clamping voltage (VC) at 97.4 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM). It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and ESD in automotive power supplies.
For engineers reviewing the SMCJ9.0AHM3_A/H datasheet, SMCJ9.0AHM3_A/H pinout, SMCJ9.0AHM3_A/H application, or SMCJ9.0AHM3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification (HM3 suffix), 1.0 μA max reverse leakage at VWM, 10.0–11.1 V breakdown range (VBR), and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold (10.0–11.1 V), limiting transient energy to ≤15.4 V at 97.4 A (10/1000 μs waveform). Its glass-passivated junction ensures stable performance under repetitive surge stress.
Designed for high-reliability automotive applications, SMCJ9.0AHM3_A/H meets AEC-Q101 qualification, features halogen-free RoHS-compliant construction (HM3 suffix), and supports operation from –55 °C to +150 °C junction temperature with MSL Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 10.0 V / 11.1 V - Breakdown occurs within this range at 1.0 mA test current, defining turn-on threshold |
| VC @ IPPM | 15.4 V - Clamped voltage seen by protected circuit during full 97.4 A transient event |
| PPPM | 1500 W - Peak transient power it can absorb without failure (10/1000 μs waveform) |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 9 V supply rails in engine control units (ECUs) from load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between 9 V rail and chassis ground to clamp transients above 11.1 V. Use Value: Limits voltage excursions to ≤15.4 V during 97.4 A surges, preventing damage to microcontrollers and analog front-ends. | Use Scenario: Safeguarding analog outputs of pressure or temperature sensors connected to PLC inputs. IC Role / Device Role / Timing Role: TVS mounted at sensor connector to shunt induced surges on 4–20 mA or 0–10 V signal lines. Use Value: 1.0 μA leakage at 9.0 V ensures no measurable error in precision analog measurements. |

IC Role / Device Role / Timing Role: Unidirectional TVS on 5 V VBUS line referenced to ground, leveraging low clamping for USB 2.0 timing margin. Use Value: 15.4 V clamping avoids false overvoltage shutdown while maintaining <1 ns response for ESD events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ9.0AHE3/A | Lower PPPM (400 W), smaller SMA package, same VWM/VC specs | Not rated for automotive under-hood; limited to consumer/industrial ambient | Select when space-constrained layouts require smaller footprint and surge energy is ≤400 W |
| SMCJ9.0AHE3_A/H | Same electrical specs but E3 (non-halogen-free) RoHS version; not AEC-Q101 qualified | Lacks automotive qualification; suitable for commercial-grade automotive subsystems (e.g., infotainment only) | Choose when halogen-free requirement is waived and AEC-Q101 is not mandated |
Compared with SMCJ9.0AHM3_A/H, SMAJ9.0AHE3/A offers reduced surge capacity in a smaller package, while SMCJ9.0AHE3_A/H retains identical robustness but omits halogen-free and AEC-Q101 compliance-making the HM3 variant the only choice for full automotive qualification.

FAQ
What is the breakdown voltage range for SMCJ9.0AHM3_A/H?
The SMCJ9.0AHM3_A/H has a guaranteed breakdown voltage (VBR) range of 10.0 V to 11.1 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This defines the minimum and maximum voltage at which the device initiates avalanche conduction, ensuring predictable clamping behavior across manufacturing lots and temperature ranges.
Is SMCJ9.0AHM3_A/H suitable for bidirectional transient protection?
No, SMCJ9.0AHM3_A/H is a unidirectional TVS diode, indicated by the "A" (not "CA") suffix and cathode band marking. For bidirectional protection, select the SMCJ9.0CA variant, which clamps symmetrically in both polarities and carries no polarity marking.
Does SMCJ9.0AHM3_A/H meet automotive qualification standards?
Yes, SMCJ9.0AHM3_A/H is AEC-Q101 qualified, as confirmed by the "HM3" suffix (halogen-free, RoHS-compliant, and AEC-Q101 qualified). This certification covers stress tests including temperature cycling, humidity bias HAST, and mechanical shock, validating suitability for under-hood automotive applications.
What is the maximum clamping voltage of SMCJ9.0AHM3_A/H at rated surge current?
The SMCJ9.0AHM3_A/H clamps to a maximum of 15.4 V when subjected to its rated 97.4 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is guaranteed across temperature and ensures protected circuits remain below critical overvoltage thresholds during surge events.
How does the HM3 suffix affect the material composition of SMCJ9.0AHM3_A/H?
The HM3 suffix indicates SMCJ9.0AHM3_A/H uses halogen-free molding compound and matte tin-plated leads, fully compliant with RoHS Directive 2011/65/EU and satisfying automotive material restrictions (e.g., JESD201 Class 2 whisker resistance). This eliminates brominated flame retardants while maintaining UL 94 V-0 flammability rating.
