Product details
Overview
SMCJ100AHM3/H 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 (VWM), 162 V clamping voltage (VC) at 9.3 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 lightning-induced surges in automotive and industrial power rails.
For engineers reviewing the SMCJ100AHM3/H datasheet, SMCJ100AHM3/H pinout, SMCJ100AHM3/H application, or SMCJ100AHM3/H equivalent, key selection criteria include its AEC-Q101 qualification, halogen-free RoHS-compliant construction (HM3 suffix), 150 °C maximum junction temperature, and verified clamping performance under 10/1000 μs waveform conditions.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its 111–123 V breakdown range (VBR) at 1 mA test current. Its glass-passivated junction ensures stable leakage (<1.0 μA at 100 V) and fast response time (<1 ns), enabling effective suppression of ESD and surge events before sensitive downstream components are damaged.
Thermally, it features RθJA = 75 °C/W and RθJL = 15 °C/W, supporting reliable operation on standard 8.0 mm × 8.0 mm copper pads. The HM3 suffix confirms halogen-free, RoHS-compliant, and AEC-Q101 qualified construction - critical for automotive ECUs and industrial control modules requiring long-term reliability under thermal cycling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100AHE3/A | Lower PPPM (600 W), same VWM (100 V), SMB package (smaller footprint, lower thermal mass) | Not suitable for IEC 61000-4-5 Level 4; limited to lower-energy surges in space-constrained consumer designs | Select when board area is critical and surge threat level is ≤1 kV/2 Ω. |
| SMCJ100A-M3/57T | Same electrical specs and SMC package, but commercial-grade (non-AEC-Q101) and non-halogen-free | Lacks automotive qualification and halogen-free compliance; acceptable for industrial non-automotive use only | Choose for cost-sensitive industrial applications where AEC-Q101 and halogen-free are not mandated. |
Compared with SMCJ100AHM3/H, SMBJ100AHE3/A trades surge robustness for compactness, while SMCJ100A-M3/57T retains identical protection capability but omits automotive qualification and halogen-free materials - making SMCJ100AHM3/H the sole choice for AEC-Q101-compliant, environmentally regulated automotive deployments.

FAQ
What is the clamping voltage of SMCJ100AHM3/H and how is it measured?
The clamping voltage (VC) of SMCJ100AHM3/H is 162 V, measured at 9.3 A peak pulse current (IPPM) under the standardized 10/1000 μs double-exponential surge waveform. This value is guaranteed per Vishay's datasheet (Document Number: 88394, Rev. 09-Jan-2024) and reflects the maximum voltage seen across the device during a worst-case transient event - directly limiting stress on downstream components protected by the SMCJ100AHM3/H.
Is SMCJ100AHM3/H suitable for automotive applications?
Yes, SMCJ100AHM3/H is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction validated for automotive use. It meets requirements for under-hood and chassis-mounted modules, including temperature cycling, high-temperature reverse bias, and mechanical shock testing - making SMCJ100AHM3/H appropriate for engine control units, body electronics, and ADAS power supplies.
What does the "HM3" suffix mean in SMCJ100AHM3/H?
The "HM3" suffix in SMCJ100AHM3/H denotes halogen-free, RoHS-compliant, and AEC-Q101 qualified construction. It distinguishes this variant from commercial-grade versions (e.g., M3 or E3) and confirms compliance with automotive environmental and reliability standards - critical for OEM approvals and long-term supply chain sustainability in vehicle platforms using the SMCJ100AHM3/H.
How does SMCJ100AHM3/H differ from bidirectional SMCJ100CA variants?
SMCJ100AHM3/H is unidirectional with cathode marking and conducts only in reverse breakdown, while SMCJ100CA is bidirectional and symmetrical - conducting in both directions. The unidirectional SMCJ100AHM3/H offers lower leakage (<1.0 μA at 100 V) and is preferred for DC power rail protection; the bidirectional version suits AC-coupled or floating signal lines where polarity reversal may occur - a functional distinction confirmed in Vishay's SMCJ5.0A–SMCJ188CA datasheet.
What is the thermal resistance and mounting requirement for optimal performance of SMCJ100AHM3/H?
SMCJ100AHM3/H has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead (RθJL) of 15 °C/W. For rated surge performance, Vishay specifies mounting on minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. Deviating from this layout reduces power dissipation capability and risks thermal runaway during repetitive surges - a requirement explicitly defined in the SMCJ100AHM3/H datasheet.
