Product details
Overview
SMCJ100AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 100 V standoff voltage, 162 V clamping voltage at 9.3 A peak pulse current, and 1500 W peak pulse power rating. It protects MOSFETs, ICs, and sensor signal lines in automotive power systems and industrial motor drives.
For engineers reviewing the SMCJ100AHM3/I datasheet, SMCJ100AHM3/I pinout, SMCJ100AHM3/I application, or SMCJ100AHM3/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, halogen-free RoHS compliance, and thermal resistance of 75 °C/W junction-to-ambient under standard pad layout.
Technical Context
This TVS diode operates as a clamping device triggered by reverse-biased avalanche breakdown above its 100 V stand-off voltage, delivering sub-nanosecond response to transients induced by inductive switching or ESD events. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM).
Rated for 1500 W peak pulse power (10/1000 μs waveform), it sustains 200 A non-repetitive forward surge current and maintains operation across -55 °C to +150 °C junction temperature range, with thermal resistance optimized for PCB copper pad cooling per JESD51-7 standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR min / max | 111 V / 123 V - breakdown occurs within this range at 1 mA test current, defining turn-on threshold |
| VC @ IPPM | 162 V - clamped voltage seen by protected circuit during full 9.3 A surge, limiting stress on downstream components |
| PPPM | 1500 W - peak transient energy absorption capability using standardized 10/1000 μs waveform |
| ID @ VWM | <1.0 μA - ultra-low reverse leakage ensures minimal standby power loss and signal integrity |
| TJ max | +150 °C - maximum junction temperature enabling use in under-hood automotive and high-temperature industrial environments |
| RθJA | 75 °C/W - thermal resistance from junction to ambient air on recommended 8 mm × 8 mm copper pads |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100AHE3/A | Lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 110 °C/W) | Not suitable for 1500 W surge events; limited to low-energy ESD or board-level transients | Select only if space-constrained and surge energy is verified ≤400 W |
| SMCJ100A-M3/57T | Same electrical specs and SMC package, but commercial-grade (non-AEC-Q101) and standard RoHS (not halogen-free) | Lacks automotive qualification and halogen-free certification required for Tier 1 OEM programs | Acceptable for industrial/commercial designs where AEC-Q101 and halogen-free are not mandated |
Compared with SMCJ100AHM3/I, SMAJ100AHE3/A offers smaller size but insufficient surge capacity for load-dump protection, while SMCJ100A-M3/57T matches performance but omits automotive qualification and halogen-free compliance needed for regulated automotive production.

FAQ
What is the clamping voltage of SMCJ100AHM3/I at its rated peak pulse current?
The SMCJ100AHM3/I has a maximum clamping voltage (VC) of 162 V when subjected to its rated peak pulse current of 9.3 A using the standard 10/1000 μs waveform. This value is measured under specified test conditions with 0.31" × 0.31" copper pads per terminal and defines the upper voltage limit imposed on protected circuitry during surge events. The SMCJ100AHM3/I maintains this clamping performance across its operational temperature range.
Is SMCJ100AHM3/I qualified for automotive applications?
Yes, SMCJ100AHM3/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HM3" indicating halogen-free, RoHS-compliant, and automotive-grade qualification. It meets stress tests including temperature cycling, high-temperature operating life, and mechanical shock per JESD22 standards. The SMCJ100AHM3/I is intended for use in engine control units, body electronics, and ADAS modules where automotive reliability is required.
What does the "HM3" suffix signify in SMCJ100AHM3/I?
The "HM3" suffix in SMCJ100AHM3/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Per Vishay's ordering nomenclature, "H" indicates AEC-Q101 qualification, "M" signifies halogen-free material, and "3" confirms RoHS compliance. This distinguishes SMCJ100AHM3/I from commercial variants like SMCJ100A-M3/57T, which lack automotive qualification despite sharing electrical specs.
How does the thermal resistance of SMCJ100AHM3/I affect PCB layout?
The SMCJ100AHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. To achieve this rating, PCB layout must provide minimum copper area per pad and avoid excessive thermal isolation. Reducing pad size or adding thermal relief increases RθJA, risking junction overheating during repeated surges. The SMCJ100AHM3/I requires adherence to Vishay's recommended pad layout for reliable thermal performance.
Can SMCJ100AHM3/I be used in bidirectional configurations?
No, SMCJ100AHM3/I is a unidirectional TVS diode, as indicated by the "A" (not "CA") suffix and cathode band marking. Bidirectional operation requires the "CA" variant (e.g., SMCJ100CA), which lacks polarity marking and conducts symmetrically in both directions. Using SMCJ100AHM3/I in reverse-biased signal paths may cause unintended conduction or failure. For AC-coupled or differential signal protection, select the appropriate CA-series part instead of SMCJ100AHM3/I.
