Overview
SMB10J7.0AHM3/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 7.0 V stand-off voltage (VWM), 7.78–8.60 V breakdown voltage (VBR) at 10 mA, 12.0 V clamping voltage (VC) at 83.3 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMB10J7.0AHM3/I datasheet, SMB10J7.0AHM3/I pinout, SMB10J7.0AHM3/I application, or SMB10J7.0AHM3/I equivalent, key selection criteria include clamping performance under 83.3 A surge, AEC-Q101 qualification status, halogen-free RoHS compliance (HM3 suffix), and compatibility with 0.2" × 0.2" copper pad layout per JEDEC standard.
Technical Context
This TVS diode operates as a unidirectional clamping device with avalanche breakdown behavior, optimized for fast response (<1 ns) to ESD and lightning-induced transients. Its glass-passivated junction ensures stable leakage (<1000 µA at VWM) and low incremental surge resistance, enabling consistent clamping across repeated surges.
The SMB10J7.0AHM3/I is rated for -55 °C to +150 °C operating junction temperature and meets MSL Level 1 per J-STD-020 (260 °C peak reflow). Its thermal resistance (RθJA = 72 °C/W, RθJL = 20 °C/W) supports reliable power dissipation in compact PCB layouts without forced cooling.

FAQ
What is the clamping voltage of SMB10J7.0AHM3/I at its rated peak pulse current?
The SMB10J7.0AHM3/I has a maximum clamping voltage (VC) of 12.0 V when subjected to its rated peak pulse current (IPPM) of 83.3 A using a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream circuitry sees no more than 12.0 V during standardized surge events - essential for protecting 12 V-tolerant interface ICs. The SMB10J7.0AHM3/I maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C).
Is SMB10J7.0AHM3/I qualified for automotive applications?
Yes, SMB10J7.0AHM3/I is AEC-Q101 qualified, as confirmed by Vishay's official documentation (Document Number: 88422, Revision: 09-Jan-2024). The HM3 suffix denotes halogen-free, RoHS-compliant construction combined with full AEC-Q101 stress testing - including HTGB, HTRB, temperature cycling, and ESD. This makes SMB10J7.0AHM3/I suitable for under-hood and cabin applications such as engine control sensors, ADAS camera modules, and body control units where automotive-grade reliability is required.
What does the "HM3" suffix mean in SMB10J7.0AHM3/I?
The "HM3" suffix in SMB10J7.0AHM3/I indicates halogen-free, RoHS-compliant construction with AEC-Q101 qualification. Specifically, "H" denotes AEC-Q101 qualification, "M" signifies halogen-free molding compound and terminations, and "3" confirms RoHS compliance per EU Directive 2011/65/EU. This triple designation distinguishes SMB10J7.0AHM3/I from commercial-grade variants (e.g., M3) and non-halogen-free automotive versions (e.g., HE3), ensuring full alignment with Tier 1 automotive material declarations and sustainability mandates.
What is the maximum peak pulse power rating for SMB10J7.0AHM3/I?
The SMB10J7.0AHM3/I has a peak pulse power rating (PPPM) of 1000 W when tested with a 10/1000 µs waveform, as specified in Vishay's datasheet (Document Number: 88422). This rating applies under standard mounting conditions: 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. Derating is required above TA = 25 °C per Figure 2 in the datasheet, with thermal resistance values RθJA = 72 °C/W and RθJL = 20 °C/W supporting accurate system-level thermal modeling for the SMB10J7.0AHM3/I.
Does SMB10J7.0AHM3/I have polarity marking, and how is it identified?
Yes, SMB10J7.0AHM3/I is a unidirectional TVS diode and features a visible cathode band on the SMB (DO-214AA) package body - located adjacent to the cathode terminal. Per Vishay's mechanical drawings and datasheet notes, this band must be aligned toward the ground or lower-potential node in the circuit. Incorrect orientation (e.g., reversed anode/cathode connection) will prevent proper clamping during positive transients and may result in catastrophic failure. The SMB10J7.0AHM3/I's polarity marking is laser-etched and verified per J-STD-020 moisture sensitivity level 1 handling requirements.
