Product details
Overview
SMB10J9.0AHM3/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 DC power rails and signal lines. It features a 9.0 V stand-off voltage (VWM), 10.0–11.1 V breakdown voltage (VBR) at 1.0 mA test current, 15.4 V clamping voltage (VC) at 64.9 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform. It is AEC-Q101 qualified and halogen-free, targeting automotive sensor interface and ECU power rail protection.
For engineers reviewing the SMB10J9.0AHM3/I datasheet, SMB10J9.0AHM3/I pinout, SMB10J9.0AHM3/I application, or SMB10J9.0AHM3/I equivalent, key selection criteria include clamping performance under 10/1000 µs surge, AEC-Q101 qualification status, unidirectional polarity for DC rail use, thermal resistance (RθJA = 72 °C/W), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamping device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold (10.0–11.1 V), limiting transient energy to protect downstream ICs. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response time (<1 ns), critical for safeguarding MOSFET gates and microcontroller I/O pins.
The SMB10J9.0AHM3/I is rated for 100 A non-repetitive forward surge current (IFSM) and operates across -55 °C to +150 °C junction temperature range. Its MSL Level 1 rating and matte tin-plated leads support lead-free reflow up to 260 °C peak, meeting J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 12 V automotive systems. |
| VBR (min/max) | 10.0 V / 11.1 V at 1.0 mA - Tight breakdown tolerance ensures predictable turn-on during transients without premature conduction. |
| VC @ IPPM | 15.4 V at 64.9 A - Clamping voltage limits stress on protected circuitry during 1000 W surge events. |
| PPPM | 1000 W (10/1000 µs) - Peak surge handling capacity suitable for ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 4 threats. |
| ID @ VWM | <1.0 µA - Ultra-low leakage preserves battery life and avoids false triggering in low-power sensor nodes. |
| TJ max. | +150 °C - Enables deployment in under-hood automotive environments and industrial motor drive control units. |
| RθJA | 72 °C/W - Thermal resistance measured on 0.2" × 0.2" copper pads; informs heatsinking requirements for sustained surge duty cycles. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ9.0AHE3/A | Same VWM (9.0 V), VBR (10.0–11.1 V), VC (15.4 V), but RoHS-compliant commercial grade (E3), not AEC-Q101 qualified or halogen-free. | Lacks automotive qualification and halogen-free certification; suitable for industrial/commercial PCBs where AEC-Q101 is not mandated. | Select SMBJ9.0AHE3/A only for non-automotive applications requiring identical electrical specs without automotive compliance overhead. |
| 1.5SMC9.0A | Same VWM (9.0 V) and VC (15.4 V), but larger SMC (DO-214AB) package (7.11 mm × 6.22 mm), higher RθJA (50 °C/W), and no AEC-Q101 or HM3 designation. | Requires more PCB area and offers inferior thermal performance; not qualified for automotive use or halogen-free requirements. | Choose 1.5SMC9.0A only if legacy SMC footprint exists and AEC-Q101/halogen-free compliance is unnecessary. |
Compared with SMBJ9.0AHE3/A and 1.5SMC9.0A, SMB10J9.0AHM3/I uniquely delivers AEC-Q101 qualification, halogen-free construction, and SMB footprint in a single solution-enabling drop-in compliance for next-gen automotive ECUs without layout or thermal redesign.

FAQ
What is the clamping voltage of SMB10J9.0AHM3/I at its rated peak pulse current?
The SMB10J9.0AHM3/I has a maximum clamping voltage (VC) of 15.4 V when subjected to its rated peak pulse current (IPPM) of 64.9 A using a 10/1000 µs waveform. This value is measured under standardized test conditions per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting for protected circuits. The SMB10J9.0AHM3/I maintains this clamping performance across its specified operating temperature range.
Is SMB10J9.0AHM3/I suitable for automotive applications?
Yes, SMB10J9.0AHM3/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction - making it suitable for automotive applications including body control modules, ADAS sensors, and infotainment power supplies. Its -55 °C to +150 °C operating junction temperature range and MSL Level 1 rating further support under-hood and cabin deployment. The SMB10J9.0AHM3/I meets all stress test requirements defined in the AEC-Q101 standard.
What does the "HM3" suffix mean in SMB10J9.0AHM3/I?
The "HM3" suffix in SMB10J9.0AHM3/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It distinguishes this variant from commercial-grade versions (e.g., E3) and confirms compliance with IPC-1752A material declarations and JEDEC J-STD-20 moisture sensitivity Level 1. The SMB10J9.0AHM3/I uses bromine- and chlorine-free molding compounds and matte tin-plated leads meeting JESD 22-B102 solderability standards.
How does SMB10J9.0AHM3/I differ from SMBJ9.0AHE3/A?
SMB10J9.0AHM3/I and SMBJ9.0AHE3/A share identical electrical parameters (VWM = 9.0 V, VBR = 10.0–11.1 V, VC = 15.4 V), but SMB10J9.0AHM3/I adds AEC-Q101 qualification and halogen-free (HM3) construction, whereas SMBJ9.0AHE3/A is commercial-grade (E3) only. The SMB10J9.0AHM3/I is intended for automotive use; SMBJ9.0AHE3/A is appropriate for non-automotive industrial or consumer applications where qualification is not required.
What is the thermal resistance of SMB10J9.0AHM3/I, and how does it affect layout?
The SMB10J9.0AHM3/I 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 minimum recommended pad layout per Vishay's datasheet; reducing pad size increases RθJA and risks thermal runaway during repetitive surges. For reliable operation, maintain the specified pad dimensions and avoid excessive trace length between the SMB10J9.0AHM3/I and ground/power planes.
