Product details
Overview
SMCJ5.0AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients up to 1500 W peak pulse power with 9.2 V maximum clamping voltage at 163 A peak pulse current. It features 5.0 V stand-off voltage, 6.40–7.07 V breakdown voltage at 10 mA test current, and operates across –55 °C to +150 °C junction temperature range. It is used to protect MOSFETs, ICs, and sensor signal lines from inductive switching surges in automotive and industrial power electronics.
For engineers reviewing the SMCJ5.0AHM3_A/I datasheet, SMCJ5.0AHM3_A/I pinout, SMCJ5.0AHM3_A/I application, or SMCJ5.0AHM3_A/I equivalent, key selection criteria include unidirectional polarity, 1500 W 10/1000 µs surge rating, 9.2 V clamping performance at rated IPPM, AEC-Q101 qualification status, and halogen-free RoHS-compliant construction per HM3 suffix.
Technical Context
This TVS diode employs a glass-passivated silicon junction optimized for fast response (<1 ps) to transient overvoltages and low incremental surge resistance. Its unidirectional configuration provides cathode-banded polarity with reverse-biased operation during surge events, enabling precise clamping above 5.0 V stand-off while maintaining <1000 µA leakage at rated VWM.
The device is thermally characterized with RθJA = 75 °C/W and RθJL = 15 °C/W, supporting reliable operation on standard 8.0 mm × 8.0 mm copper pads. It meets MSL Level 1 per J-STD-020 and is qualified to AEC-Q101 for automotive underhood applications when ordered with HM3 suffix.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0AHE3/A | Lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 110 °C/W) | Suitable for lower-energy transients in space-constrained consumer designs; not AEC-Q101 qualified | Select when board space is critical and surge threat level is ≤400 W; verify thermal margin at 50 °C ambient |
| SMCJ5.0AHE3_A/I | Same electrical specs but E3 suffix: RoHS-compliant commercial grade, non-halogen-free, no AEC-Q101 qualification | Applicable in non-automotive industrial or telecom systems where halogen-free and automotive qualification are not mandated | Choose for cost-sensitive commercial applications requiring identical clamping performance without HM3-specific compliance |
Compared with SMCJ5.0AHM3_A/I, SMAJ5.0AHE3/A offers smaller size but reduced surge capacity and thermal robustness, while SMCJ5.0AHE3_A/I matches all electrical parameters but lacks halogen-free content and AEC-Q101 validation-making SMCJ5.0AHM3_A/I the sole choice for automotive-grade, environmentally compliant 1500 W clamping.

FAQ
What is the clamping voltage of SMCJ5.0AHM3_A/I at its rated peak pulse current?
The SMCJ5.0AHM3_A/I has a maximum clamping voltage (VC) of 9.2 V when subjected to its rated 10/1000 µs peak pulse current of 163 A. This value is measured under standardized test conditions per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting for protected circuits. The clamping performance is guaranteed across the full operating temperature range and forms the basis for safe margin design in 5 V systems.
Is SMCJ5.0AHM3_A/I qualified for automotive applications?
Yes, SMCJ5.0AHM3_A/I is AEC-Q101 qualified, as confirmed by the HM3 suffix in its ordering code. This qualification covers stress tests including temperature cycling, high-temperature operating life, and mechanical shock-validating its suitability for underhood automotive applications such as engine control units and body electronics. The device's –55 °C to +150 °C junction temperature range further supports this use case.
How does the HM3 suffix differ from the HE3 suffix in SMCJ5.0A variants?
The HM3 suffix on SMCJ5.0AHM3_A/I denotes halogen-free, RoHS-compliant, and AEC-Q101 qualified construction, whereas HE3 indicates RoHS-compliant and AEC-Q101 qualified but not halogen-free. Both meet automotive reliability standards, but HM3 adds compliance with halogen-free material requirements (e.g., IEC 61249-2-21), making it suitable for stricter environmental mandates in Tier 1 automotive supply chains.
What is the thermal resistance from junction to ambient for SMCJ5.0AHM3_A/I?
The typical thermal resistance from junction to ambient (RθJA) for SMCJ5.0AHM3_A/I is 75 °C/W when mounted on the recommended 8.0 mm × 8.0 mm copper pads per terminal. This value assumes free-air convection and is critical for calculating maximum power dissipation at elevated ambient temperatures. Derating curves in the Vishay datasheet (Fig. 2) must be applied for operation above 25 °C ambient.
Can SMCJ5.0AHM3_A/I be used in bidirectional configurations?
No, SMCJ5.0AHM3_A/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., SMCJ5.0CA), which has symmetrical breakdown in both directions. Using SMCJ5.0AHM3_A/I in bidirectional applications would result in forward conduction on one half-cycle, potentially damaging the device or failing to suppress transients.
